Spray-on hair was one of the products pioneered by Ronco in the 1980s, under the name "GLH-9" (Great Looking Hair Formula #9). [2] The product "was popular in the 1990s with 30-minute infomercials for the product on late-night cable TV", [ 3 ] and the Ronco version sold over a half million cans. [ 3 ]
Cryogenic grinding, also known as freezer milling, freezer grinding, and cryomilling, is the act of cooling or chilling a material and then reducing it into a small particle size. For example, thermoplastics are difficult to grind to small particle sizes at ambient temperatures because they soften, adhere in lumpy masses and clog screens.
The cryogenic treatment process was invented by Ed Busch (CryoTech) in Detroit, Michigan in 1966, inspired by NASA research, which later merged with 300 Below, Inc. in 2000 to become the world's largest and oldest commercial cryogenic processing company after Peter Paulin of Decatur, IL collaborated with process control engineers to invent the world's first computer-controlled "dry" cryogenic ...
A cryogenic processor is a device engineered to reduce the temperature of an object to cryogenic levels, typically around −300°F (−184.44°C), at a moderate rate in order to prevent thermal shock to the components being treated. The inception of commercial cryogenic processors dates back to the late 1960s, pioneered by Ed Busch. [1]
Early hair tongs. A hair iron is a tool used to change the structure of the hair with the help of heat. There are three general kinds: curling tongs, also known as curling irons, [2] used to make the hair curly; straighteners, also known as flat irons, [3] used to straighten the hair; and crimpers, [4] used to create small crimps in the hair.
A woman with dyed pink hair. Hair coloring, or hair dyeing, is the practice of changing the color of the hair on humans' heads.The main reasons for this are cosmetic: to cover gray or white hair, to alter hair to create a specific look, to change a color to suit preference or to restore the original hair color after it has been discolored by hairdressing processes or sun bleaching.
Cryogenic hardening is a cryogenic treatment process where the material is cooled to approximately −185 °C (−301 °F), typically using liquid nitrogen. It can have a profound effect on the mechanical properties of certain steels , provided their composition and prior heat treatment are such that they retain some austenite at room temperature.
Determining the fineness of a paint's grind is important, because too coarse a grind may reduce the paint's color uniformity, gloss, and opacity. [7] The Hegman gauge is widely used for this purpose because it requires minimal skill and only a few seconds' work.
