,079 for the invention of the torque wrench.1918 Crystal oscillator A crystal oscillator is an electronic circuit that uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a very precise frequency. This frequency is commonly used to keep track of time as used in quartz wristwatches, to provide a stable clock signal for digital integrated circuits, and to stabilize frequencies for radio transmitters and receivers. The first crystal-controlled oscillator, using a crystal of Rochelle Salt, was invented by Alexander M. Nicholson. However, it is generally accepted that Dr. Walter Guyton Cady was the first to use a quartz to control the frequency of an oscillator circuit. Nevertheless, Nicholson is still regarded as the inventor of the crystal oscillator.1918 Grocery bag Shopping bags are medium-sized bags, typically around 10–20 litres (2.5 to 5 gallons) in volume, that are often used by grocery shoppers to carry home their purchases. They can be single-use (disposable), used for other purposes or designed as reusable shopping bags. The grocery bag with handles was invented in 1918 by Walter Deubener of St. Paul Minnesota. U.S. patent #1,305,198 was issued to Deubener on May 27, 1919.1918 Hydraulic brake The hydraulic brake is an arrangement of braking mechanism which uses brake fluid, typically containing ethylene glycol, to transfer pressure from the controlling unit, which is usually near the operator of the vehicle, to the actual brake mechanism, which is usually at or near the wheel of the vehicle. In 1918, the hydraulic brake was invented by Malcolm Loughead, which replaced the mechanical brake which was used previously on automobiles.1919 Blender A blender is an upright, stationary kitchen appliance used to mix alcoholic beverages and puree food. Blenders are also used to prepare emulsions, such as mayonnaise, and cream soups. In 1919, Polish-American Stephen J. Poplawski of Racine, Wisconsin invented, designed, and manufactured beverage mixers used in preparation for malted milk served at soda fountains. It consisted of a spinning blade on a long rod extending down into a cup. Poplawski patented his invention of the blender in 1922.1919 Silica gel Silica gel is a granular, porous form of silica made from sodium silicate. Silica gel is a solid.
