A clutch is a mechanical device that allows an output shaft to be disconnected from a rotating input shaft. The clutch's input shaft is typically attached to a motor, while the clutch's output shaft is connected to the mechanism that does the work.
A centrifuge is a device that uses centrifugal force to subject a specimen to a specified constant force, for example to separate various components of a fluid. This is achieved by spinning the fluid at high speed within a container, thereby separating fluids of different densities or liquids from solids. It works by causing denser substances and particles to move outward in the radial direction. At the same time, objects that are less dense are displaced and moved to the centre. In a laboratory centrifuge that uses sample tubes, the radial acceleration causes denser particles to settle to the bottom of the tube, while low-density substances rise to the top. A centrifuge can be a very effective filter that separates contaminants from the main body of fluid.
A washing machine is a machine designed to launder clothing. Modern-day home appliances use electric power to automatically clean clothes. The term is mostly applied to machines that use water as opposed to dry cleaning or ultrasonic cleaners. The user adds laundry detergent, which is sold in liquid, powder, or dehydrated sheet form, to the wash water.
A power take-off or power takeoff (PTO) is one of several methods for taking power from a power source, such as a running engine, and transmitting it to an application such as an attached implement or separate machine.
The Honda XR series is a range of four-stroke off-road motorcycles that were designed in Japan but assembled all over the world.
Rendering is a process that converts waste animal tissue into stable, usable materials. Rendering can refer to any processing of animal products into more useful materials, or, more narrowly, to the rendering of whole animal fatty tissue into purified fats like lard or tallow. Rendering can be carried out on an industrial, farm, or kitchen scale. It can also be applied to non-animal products that are rendered down to pulp. The rendering process simultaneously dries the material and separates the fat from the bone and protein, yielding a fat commodity and a protein meal.
A dynamometer or "dyno" for short, is a device for simultaneously measuring the torque and rotational speed (RPM) of an engine, motor or other rotating prime mover so that its instantaneous power may be calculated, and usually displayed by the dynamometer itself as kW or bhp.
A bench grinder is a benchtop type of grinding machine used to drive abrasive wheels. A pedestal grinder is a similar or larger version of grinder that is mounted on a pedestal, which may be bolted to the floor or may sit on rubber feet. These types of grinders are commonly used to hand grind various cutting tools and perform other rough grinding.
The phrase speeds and feeds or feeds and speeds refers to two separate velocities in machine tool practice, cutting speed and feed rate. They are often considered as a pair because of their combined effect on the cutting process. Each, however, can also be considered and analyzed in its own right.
"Dem Bones" is a spiritual song. The melody was composed by author and songwriter James Weldon Johnson (1871–1938) and his brother, J. Rosamond Johnson. It was first recorded by The Famous Myers Jubilee Singers in 1928. Both a long and a shortened version of the song are widely known. The lyrics are inspired by Ezekiel 37:1–14, in which the prophet Ezekiel visits the Valley of Dry Bones and prophesies that they will one day be resurrected at God's command, picturing the realization of the New Jerusalem.
The Bone Valley is a region of central Florida, encompassing portions of present-day Hardee, Hillsborough, Manatee, and Polk counties, in which phosphate is mined for use in the production of agricultural fertilizer. Florida currently contains the largest known deposits of phosphate in the United States.
Bone meal is a mixture of finely and coarsely ground animal bones and slaughter-house waste products. It is used as a dietary supplement to supply calcium and phosphorus to monogastric livestock in the form of hydroxyapatite. As a slow-release organic fertilizer, it supplies phosphorus, calcium, and a small amount of nitrogen to plants.
Rokon is an American Rochester, New Hampshire-based motorcycle manufacturer that builds two-wheel-drive off-road motorcycles which are marketed either under the company's name, or as the "Trail Breaker". Robert Korpi was also owner of Rokon International from about 1976 to 1990
Fish meal, sometimes spelt fishmeal, is a commercial product made from whole wild-caught fish, bycatch, and fish by-products to feed farm animals, e.g., pigs, poultry, and farmed fish. Because it is calorically dense and cheap to produce, fishmeal has played a critical role in the growth of factory farms and the number of farm animals it is possible to breed and feed.
Formula 1000 (F1000) is a class of open wheel formula racing with professional and amateur series worldwide. Formula 1000 gets its name from the 1000 cc super-bike engine used to power a single seat, open wheel race car with fully adjustable wings and suspension.
Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. Every gravitational method uses gravity as the primary force for separation. One type of gravity separator lifts the material by vacuum over an inclined vibrating screen covered deck. This results in the material being suspended in air while the heavier impurities are left behind on the screen and are discharged from the stone outlet. Gravity separation is used in a wide variety of industries, and can be most simply differentiated by the characteristics of the mixture to be separated - principally that of 'wet' i.e. - a suspension versus 'dry' -a mixture of granular product. Often other methods are applied to make the separation faster and more efficient, such as flocculation, coagulation and suction. The most notable advantages of the gravitational methods are their cost effectiveness and in some cases excellent reduction. Gravity separation is an attractive unit operation as it generally has low capital and operating costs, uses few if any chemicals that might cause environmental concerns and the recent development of new equipment enhances the range of separations possible.
Wasanbon (和三盆) is a fine-grained Japanese sugar, traditionally made in the Shikoku prefectures of Tokushima and Kagawa, centered to the towns of Kamiita-cho and Donari-cho in Tokushima, where it has been made since about the 1770s. The sugar is often used for Japanese sweets. The sugar is made from thin sugarcane plants grown locally in Shikoku, called taketō (竹糖) or chikusha (竹蔗).
Meat and bone meal (MBM) is a product of the rendering industry. It is typically about 48–52% protein, 33–35% ash, 8–12% fat, and 4–7% water. It is primarily used in the formulation of animal feed to improve the amino acid profile of the feed. Feeding of MBM to cattle is thought to have been responsible for the spread of BSE ; therefore, in most parts of the world, MBM is no longer allowed in feed for ruminant animals. However, it is still used to feed monogastric animals.
A gristmill grinds cereal grain into flour and middlings. The term can refer to either the grinding mechanism or the building that holds it. Grist is grain that has been separated from its chaff in preparation for grinding.
Hidden Cave is an archaeological cave site located in the Great Basin near Fallon, Nevada, United States. It got its name from Mark Harrington, who first excavated the cave and had a hard time finding the entrance, who said at the time, "This is one hidden cave!" It was excavated originally in the 1930s by Harrington and then excavated twice more before being returned to for the final time in 1978 by David Hurst Thomas for a more in depth excavation. The site dates back to the early Desert Archaic Culture from c. 4000 to 2000 years ago. Thousands of Archaic artifacts have been found here, and the site "provides important, if unusual clues about Desert Archaic lifeways". Hidden Cave was not lived in, but used as storage site for goods and tools for the 2000 years of its survival.
