Laboratory Equipment
A laboratory (; ; colloquially lab) is a facility that provides controlled conditions in which scientific or technological research, experiments, and measurement may be performed. Laboratories are found in a variety of settings such as schools, universities, privately owned research institutions, corporate research and testing facilities, government regulatory and forensic investigation centers, physicians' offices, clinics, hospitals, regional and national referral centers, and even occasionally personal residences. Overview The organisation and contents of laboratories are determined by the differing requirements of the specialists working within. A physics laboratory might contain a particle accelerator or vacuum chamber, while a metallurgy laboratory could have apparatus for casting or refining metals or for testing their strength. A chemist or biologist might use a wet laboratory, while a psychologist's laboratory might be a room with one-way mirrors and hidden cameras in ...

Rubbers
Rubber, also called India rubber, latex, Amazonian rubber, ''caucho'', or ''caoutchouc'', as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds. Types of polyisoprene that are used as natural rubbers are classified as elastomers. Currently, rubber is harvested mainly in the form of the latex from the Pará rubber tree (''Hevea brasiliensis'') or others. The latex is a sticky, milky and white colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called "tapping". Manufacturers refine this latex into the rubber that is ready for commercial processing. Natural rubber is used extensively in many applications and products, either alone or in combination with other materials. In most of its useful forms, it has a large stretch ratio and high resilience and also is buoyant and water-proof. Industrial demand for rubber-like materials began to outstrip natural rubber ...

Melvin Mooney
Melvin Mooney (1893–1968) was an American physicist and rheologist. Life Mooney was born in Kansas City, Missouri.J. H. Dillon (1948) J. Colloid Sci. 4 (3) 187-8 "Introduction of Melvin Mooney as E. C. Bingham Medallist" He achieved an A.B. degree from the University of Missouri in 1917 and a PhD in physics from the University of Chicago in 1923. He worked for the United States Rubber Company. He developed the Mooney viscometer (used to measure viscosity of rubber compounds during curing) and other testing equipment used in the rubber industry. He also proposed the Mooney-Rivlin solid constitutive law describing the hyperelastic stress–strain behavior of rubber. He was the first recipient of the Bingham Medal from the Society of Rheology in 1948. He received the Charles Goodyear Medal in 1962. He is the namesake of the Melvin Mooney Distinguished Technology Award of the American Chemical Society The American Chemical Society (ACS) is a scientific society based ...

Spindle (tool)
In machine tools, a spindle is a rotating axis of the machine, which often has a shaft at its heart. The shaft itself is called a spindle, but also, in shop-floor practice, the word often is used metonymically to refer to the entire rotary unit, including not only the shaft itself, but its bearings and anything attached to it ( chuck, etc.). Spindles are electrically or pneumatically powered and come in various sizes. They are versatile in terms of material it can work with. Materials that spindles work with include embroidery, foam, glass, wood, etc. A machine tool may have several spindles, such as the headstock and tailstock spindles on a bench lathe. The main spindle is usually the biggest one. References to "the spindle" without further qualification imply the main spindle. Some machine tools that specialize in high-volume mass production have a group of 4, 6, or even more main spindles. These are called multispindle machines. For example, gang drills and many screw m ...

Die (manufacturing)
A die is a specialized machine tool used in manufacturing industries to cut and/or Forming (metalworking), form material to a desired shape or profile. ''Stamping (metalworking), Stamping dies'' are used with a machine press, press, as opposed to ''Draw plate, drawing dies'' (used in the manufacture of wire) and ''Die casting, casting dies'' (used in Molding (process), molding) which are not. Like molds, dies are generally customized to the item they are used to create. Products made with dies range from simple paper clips to complex pieces used in advanced technology. Continuous production, Continuous-feed laser cutting may displace the analogous die-based process in the automotive industry, among others. Die stamping Blanking and piercing are two Shearing (manufacturing), die cutting operations, and Bending (metalworking), bending is an example of a die forming operation. Die forming Forming operations work by deforming materials like sheet metal or plastic using force (Compre ...
