  • Magnetron sputtering method and apparatus for compound thin films
    Patent number: 5405517
    Abstract: An apparatus is described for depositing a thin film (9) of compound materials on selected substrates (48) in an evacuable coating chamber. This apparatus includes a rotating primary surrogate magnetron cathode surface (19) which acts to receive, in-situ, material to be sputtered. Vapor crucibles (2) expose the rotating cathode surface (19) to material vapors (8) which condense on the thermally cooled cathode surface (19) to combine with other coatings on the cathode and are thence rotated through the associated plasma sputter zone (26P) to sputter deposit desired film (9). Auxiliary rotating magnetron cathodes (32) can deposit additional material onto rotating primary cathode (19). Molten material crucible assemblies (31) having coating rollers (34) can convey molten material onto rotating auxiliary thermally cooled cathode surfaces (32) which sputter coat primary cathode.

  • Shampoo compositions
    Patent number: 5393519
    Abstract: A hair shampoo composition comprising a cleansing surfactant; a water-insoluble hair treating compound, like a hair conditioner or an antidandruff agent; a suspending agent comprising an amine including at least one long carbon chain and a suitable acid; and a suitable carrier, and a method of treating hair are disclosed. The shampoo compositions effectively suspend the water-insoluble hair-treating compound, effectively cleanse the hair and effectively deliver the water-insoluble hair-treating compound to the hair or scalp.

  • Opacifier for water-based compositions
    Patent number: 5384114
    Abstract: An opacifier comprising an amine including at least one carbon chain of at least 16 carbon atoms or a fatty amidoamine having an alkyl group including at least about thirteen carbon atoms, and a suitable acid is disclosed. The opacifier is a salt of the long-chain amine and effectively opacifies, or pearlizes, water-based compositions, such as hair treating compositions, like shampoos, conditioners, conditioning shampoos and antidandruff shampoos; and skin treating compositions, like conditioners, moisturizers and topical medicaments.

  • Cysteamine permament wave composition and method
    Patent number: 5382426
    Abstract: A single formula, mild permanent wave reducing composition and method of permanently waving or reshaping human hair that provides a strong, long lasting curl and leaves the hair soft while minimizing further damage to already damaged hair. The composition contains a cysteamine reducing agent compound selected from the group consisting of cysteamine, a cysteamine salt, and mixtures thereof. The cysteamine compound should be present in an amount of about 7.8% to about 9.0% by weight; and sufficient additional alkali, if necessary, to bring the pH of the composition to about 7.8 to about 8.5. Optionally, a hair softening and/or moisturizing agent, such as glycerine is included in the composition in an amount of about 0.1% to about 15% by weight of the composition.

  • Electric motor controller
    Patent number: 5374881
    Abstract: A motor controller comprises a plug detect circuit which detects "continuous" plug diode conduction during plug braking. The plug detect circuit detects "continuous" plug braking by detecting when a plug diode is or is not conducting current throughout substantially the entire time that a power MOSFET controlling the plug braking is conductive in one pulse width modulated MOSFET switching cycle. Continuous plug detection facilitates the motor controller's controlling a vehicle so that the vehicle has a more constant and smooth plug braking deceleration and subsequent powered acceleration in the opposite direction. According to another aspect of the invention, a motor controller comprises a POT HI and a POT LO driver circuit. The POT HI and POT LO driver circuits allow the detection of faults in throttle devices and the connections of the throttle devices to the POT HI and POT LO driver circuits.

  • Cysteamine permanent wave composition and method
    Patent number: 5362487
    Abstract: A single formula, mild permanent wave reducing composition and method of permanently waving or reshaping human hair that provides a strong, long lasting curl and leaves the hair soft while minimizing further damage to already damaged hair. The composition contains a cysteamine reducing agent compound selected from the group consisting of cysteamine, a cysteamine salt, and mixtures thereof; and a second reducing agent selected from the group consisting of a monothioglycolate; an alkanolamine salt of thioglycolic acid; a thiolactic acid; a thioglycolic acid; thioglycerin; salts of thiolactic acid; cysteine; a salt of cysteine; a sulfite; a hyposulfite; and a bisulfite. The cysteamine compound should be present in an amount of about 7.8% to about 9% by weight; and sufficient additional alkali, if necessary, to bring the pH of the composition to about 7.8 to about 8.8.

  • In-situ polymerization of oligomers onto hair
    Patent number: 5362486
    Abstract: An aqueous, alcoholic or hydroalcholic composition containing one or more oligomers or prepolymers that are polymerized in-situ, while the oligomer(s) is in contact with the hair, for in-situ formation (polymerization) of a polymer. The oligomer compositions contain essentially no toxic, hazardous or harmful monomer(s), such as resorcinol.
