List of Items in this Volume Air Purifier Air purifiers evolved in response to people's reactions to allergens like pollen, animal dander, dust, and mold spores. Reactions (sneezing, runny nose, scratchy eyes, and even more severe consequences such as asthma attacks) are the result of antigens found in the home. Amber Although considered a gem, amber is a wholly-organic material derived from the resin of extinct species of trees. In the dense forests of the Middle Cretaceous and Tertiary periods, between 10 and 100 million years ago, these resin-bearing trees fell and were carried by rivers to coastal regions. Aneroid Barometer Earth's atmosphere weighs about 6.5 × 1021 (5.98 × 1024). Spread out across Earth's entire surface area, it exerts an air (barometric) pressure of about 14.7 pounds per square inch (psi) (101 kilopascals [kPa]) at sea level. Bank Vault A bank vault is a secure space where money, valuables, records, and documents can be stored. Vaults protect their contents with armored walls and a tightly fashioned door closed with a complex lock. Binocular Modern binoculars consist of two barrel chambers with an objective lens, eyepiece, and a pair of prisms inside. The prisms reflect and lengthen the light, while the objective lenses enhance and magnify images due to stereoscopic vision. Brandy The name brandy comes from the Dutch word brandewijn, meaning "burnt wine." The name is apt as most brandies are made by applying heat, originally from open flames, to wine. The heat drives out and concentrates the alcohol naturally present in the wine. Breath Alcohol Tester There is a serious need to ensure that alcohol-impaired drivers stay off the roads. It is estimated that one person is killed every 32 minutes and another person is injured every 26 seconds in alcohol-related accidents.Bullet A bullet is a projectile, often a pointed metal cylinder, that is shot from a firearm. The bullet is usually part of an ammunition cartridge, the object that contains the bullet and that is inserted into the firearm. Cash Register The cash register is an essential business tool that is often overlooked as one of the transforming mechanizations of the industrial age. A cash register records the amount of a sale, supplies a receipt to the customer, and keeps a permanent journal of daily transactions. Catheter A catheter is a flexible tube made of latex, silicone, or Teflon that can be inserted into the body creating a channel for the passage of fluid or the entry of a medical device. For many years, the epidermal catheters used were plain tubes made of available industrial compounds, and design was largely based on current need. Corset The corset is an undergarment traditionally made of stiffened material laced tight to the body in order to slim a woman's waist. Evidence shows that some type of waist-cinching garment was worn by Cretan women between 3000 and 1500 B.C., but narrow waists became the fashion among women in Europe during the Middle Ages. Cyclotron The modern cyclotron uses two hollow D-shaped electrodes held in a vacuum between poles of an electromagnet. A high frequency AC voltage is then applied to each electrode. Diving Bell Commercial divers doing underwater construction or salvage often use a diving bell for transportation to the underwater site. Use of a diving bell (also known as a Personal Transfer Capsule, PTC) and a pressure chamber extends the amount of time a diver can safely stay underwater. Dry Ice Dry ice is the name given to carbon dioxide when it is in a solid state. Carbon dioxide is found in the earth's atmosphere; it is a gas that humans exhale and plants use for photosynthesis.EEG Machine An electroencephalogram (EEG) machine is a device used to create a picture of the electrical activity of the brain. It has been used for both medical diagnosis and neurobiological research. Electric Guitar Developed in the early part of the twentieth century, the electric guitar has become one of the most important instruments in popular music. Today's solid-body electric guitar derives from the acoustic guitar, an instrument first introduced in America as the Spanish-style guitar. Electric Tea Kettle The sole purpose of the tea kettle is to boil water. Water for coffee and for many cooking uses does not have to be boiled, but fresh, cool water that is brought fully to a boil is essential for tasty tea. External Defibrillator An external defibrillator is a device that delivers an electric shock to the heart through the chest wall. This shock helps restore the heart to a regular, healthy rhythm. Fabric Softener A fabric softener is a liquid composition added to washing machines during the rinse cycle to make clothes feel better to the touch. These products work by depositing lubricating chemicals on the fabric that make it feel softer, reduce static cling, and impart a fresh fragrance. Felt Most fabrics are woven, meaning they are constructed on a loom and have interlocking warp (the thread or fiber that is strung lengthwise on the loom) and weft (the thread that cuts across the warp fiber and interlocks with it) fibers that create a flat piece of fabric. Felt is a dense, nonwoven fabric and without any warp or weft. Fluoride Treatment A fluoride treatment is a mineral solution applied to teeth in order to strengthen them and help prevent cavities. Fluoride containing products include commercially available toothpaste and mouth rinse, as well as more concentrated liquids and gels used professionally by dentists. Fountain PenHumans have used various instruments to convey thoughts and feelings. Man's first writing instrument was his finger, using it to form symbols in the dirt. Furnace A furnace is a device that produces heat. Not only are furnaces used in the home for warmth, they are used in industry for a variety of purposes such as making steel and heat treating of materials to change their molecular structure. Glucometer Test Kit Diabetes mellitus effects an estimated 16 million people in the United States. An additional five million people have the disease and do not realize it. Grenade Grenades come in a variety of sizes and shapes depending on their function, but all have two things in common. First, they are hollow to allow filling with explosive or chemical filler. Guillotine The guillotine evokes images of horrifying and bloody public executions during the French Revolution in the eighteenth century. Many historians consider this device the first execution method that lessened the victim's pain and the first step in raising public awareness of the morality of the death penalty. Hair Dryer A hair dryer, also known as a blow dryer, is an electrical device used to dry and style hair. It uses an electric fan to blow air across a heating coil; as the air passes through the dryer it heats up. Handcuffs Handcuffs are standard law enforcement and security industry tools used for restraining and controlling dangerous or unreasonable people. Police officers routinely use handcuffs in their work. Insulin Insulin is a hormone that regulates the amount of glucose (sugar) in the blood and is required for the body to function normally. Insulin is produced by cells in the pancreas, called the islets of Langerhans.Kerosene Kerosene is an oil distillate commonly used as a fuel or solvent. It is a thin, clear liquid consisting of a mixture of hydrocarbons that boil between 302°F and 527°F (150°C and 275°C). Laser Pointer The laser pointer is a low cost portable laser that can be carried in the hand. It is designed for use during presentations to point out areas of the slide or picture being presented, replacing a hand held wooden stick or extendable metal pointer. Lawn Sprinkler The lawn sprinkler is a mechanism through which water is distributed in a spray so that a residential lawn or garden is irrigated. Sprinklers may take extraordinarily large forms, such as the irrigation systems used by professional farmers to water crops in the field. Lighter The discovery of tobacco in the New World in the sixteenth century and the opening of a worldwide market created the need for a portable way to make fire. Pieces of flint and steel struck against each other and modified pistols were early devices. Maracas One of the most recognizable of the percussion instruments is the maracas, a pair of rattles made from gourds. Maracas are essential to Latin and South American orchestras and bands, and other musical forms that have adopted the rhythm of the maracas. Microphone A microphone is a device that converts mechanical energy waves or sound into electrical energy waves. Speaking into a microphone excites (moves) a diaphragm that is coupled to a device that creates an electrical current proportional to the sound waves produced. Movie Projector The inspiration for the development of motion pictures and projectors can be traced to a variety of sources including theaters, circuses, and magic shows. Another important factor was the understanding of the phenomenon of persistence of vision. Night ScopeNight scopes, or night vision devices, are used to intensify human sight under very low light conditions. There are several types of night vision scopes. Oxygen Tank Oxygen (atomic number, 8; atomic weight, 16) is essential for all living things and has the ability to combine with almost all other elements. When elements fuse with oxygen, they are labeled as being oxidized. Pizza A pizza is a round, open pie made with yeast dough and topped with tomato sauce, cheese, and a variety of other ingredients. Pyrex Pyrex glass is a borosilicate glass first produced by The Corning Glass Works company. It is made by heating raw materials like silica sand and boric oxide to extremely high temperatures for extended periods of time. Radio The radio receives electromagnetic waves from the air that are sent by a radio transmitter. Electromagnetic waves are a combination of electrical and magnetic fields that overlap. Revolving Door A revolving door is used to control traffic or heating and air conditioning in a building. The revolving door structure consists of individual door panels (or wings), a center shaft with the hardware needed to support the door wings, a circular structure called a "rotunda" or "drum" that is usually fitted with glass, and the ceiling (supported by the rotunda) that contains either a mechanical braking device (used to control the speed of the doors) or an electronic device that uses a motor to drive the doors automatically. Rubik's Cube Rubik's cube is a toy puzzle designed by Erno Rubik during the mid-1970s. It is a cube-shaped device made up of smaller cube pieces with six faces having differing colors. ScaleThe traditional bathroom scale is used to measure a person's body weight. It is based on a spring system that uses the weight of the person to depress a lever, which in turn rotates a sprocket attached to the dial. Shrapnel Shell There has always been a high demand among military strategists for economical means of killing enemy soldiers. Economy is required not so much to save money, but to allow outnumbered soldiers the opportunity to win battles. Sleeping Pill A sleeping pill, also commonly called a sleep aid, is a drug that helps a person fall asleep or remain sleeping. Disorders such as insomnia (inability to sleep) are widespread, and drugs to induce sleep have been used since ancient times. Speedometer A speedometer is a device used to measure the traveling speed of a vehicle, usually for the purpose of maintaining a sensible pace. Its development and eventual status as a standard feature in automobiles led to the enforcement of legal speed limits, a notion that had been in practice since the inception of horseless carriages but had gone largely ignored by the general public. Spinning Wheel A spinning wheel is a machine used to turn fiber into thread or yarn. This thread or yarn is then woven as cloth on a loom. Spray Paint Spray paint is an aerosol product designed to be dispensed as a fine mist. Compared to conventional brush methods of painting, spray painting is faster and provides a more uniform application. Stereo Speaker A loudspeaker or speaker is a device that converts electrical energy waves into mechanical energy waves or audible sounds. Sound is produced by the vibration of an object. Stirling Cycle EngineAn engine is a machine that converts energy into useful work: burning coal to turn the drive shaft of a power plant generator, for example. The most common engine in production today is the gasoline-powered automobile engine. Sushi Roll A sushi roll is a food of Asian origin that features rice and seafood wrapped in seaweed (nori). Until the end of the twentieth century, sushi rolls were only available in restaurants. Suture A surgical suture is used to close the edges of a wound or incision and to repair damaged tissue. There are many kinds of sutures, with different properties suitable for various uses. Tattoo A tattoo is a design that is permanently etched in the skin using needles and ink. The word tattoo is derived from the Tahitian term "tatua," which means "to mark." Tattoos have been displayed by people of all cultures for centuries, but they have only recently gained social acceptance in the United States. Teflon Teflon is the registered trade name of the highly useful plastic material polytetrafluoroethylene (PTFE). PTFE is one of a class of plastics known as fluoropolymers. Tiara Tiaras are marks of distinction and style worn by women of royalty and for special events such as pageants, proms, and weddings. Revivals of interest in romantic ensembles, like those seen in movies and in period costumes, make tiaras fascinating headdresses. Titanium Titanium is known as a transition metal on the periodic table of elements denoted by the symbol Ti. It is a lightweight, silver-gray material with an atomic number of 22 and an atomic weight of 47.90. Toaster A toaster is a small appliance that uses heat to brown and harden bread.Tuxedo The tuxedo is a man's tailored suit used for semi-formal or formal wear. It may be sewn from a wide variety of colors and fabrics; increasingly, brighter colors and unconventional designs are pervasive in tuxedo styling. Typewriter Typewriters fall into five classifications. The standard typewriter was the first kind manufactured. Unicycle A unicycle is a single-wheeled vehicle traditionally used during circus performances. It consists of a spoke wheel, pedals, and a tube shaped body attached to a seat. Vending Machine From humble single-cent beginnings, vending operations in the United States have evolved into a $36.6 billion industry. Canned cold drinks were the industry's top sellers in 1999, posting $15.7 billion in sales and accounting for 42.9% of the industry's gross sales volume. Vinegar Vinegar is an alcoholic liquid that has been allowed to sour. It is primarily used to flavor and preserve foods and as an ingredient in salad dressings and marinades. Windmill A windmill is a structure or machine that converts wind into usable energy through the rotation of a wheel made up of adjustable blades. Traditionally, the energy generated by a windmill has been used to grind grain into flour.
