Patent number: 5205954Abstract: The application is directed to an automatic dishwasher powder detergent composition with improved anti-filming and anti-spotting properties and to a method of using the detergent composition. The detergent composition comprises silica anti-filming agent, a water soluble polyacrylate antispotting agent, inorganic builder salts, chlorine bleach and bleach-stable detergent. The compositions provide reduced filming and spotting on dishware, glassware, china and the like, particularly in hard water at low temperature. The powder compositions are dry, free flowing and are highly soluble and readily dispersed in the wash bath.Type: GrantFiled: July 15, 1991Date of Patent: April 27, 1993Assignee: Colgate-Palmolive Co.Inventors: Fahim U.

Patent number: 5108642Abstract: A solid detergent composition for cleaning hard surfaces comprises an active detergent constituent which also serves as a carrier material, and a cleaning constituent. The cleaning constituent can comprise an acidic material, which is effective to remove soap scum from hard surfaces, or a bleach functional at a basic pH which is effective to bleach mildew. The detergent constituent comprises the essentially anhydrous neutralization product of an anionic surfactant such as a linear alkylbenzene sulfonic acid and a solid neutralizing material, such as a salt, oxide, or hydroxide of an alkali or alkaline earth metal, including sodium carbonate. The cleaning constituent, along with a filler material, is added to the detergent constituent during the course of and prior to the termination of the neutralization reaction. Also disclosed is a reusable scrubber pad incorporating the solid detergent composition.Type: GrantFiled: March 28, 1990Date of Patent: April 28, 1992Assignee: Colgate-Palmolive CompanyInventors: Harry W.

Patent number: 4263363Abstract: A water-in-oil emulsion at a ratio of 80/20 or less when incorporated into a water absorbing material (such as a polyurethane sponge) will aid in retaining water that may be subsequently added to the absorbing material. The effect is believed due to the increased viscosity of the emulsion when water is added. The effect is particularly useful for improving urine retention of diapers, such as disposable diapers or similar articles.Type: GrantFiled: December 20, 1979Date of Patent: April 21, 1981Assignee: Colgate-Palmolive CompanyInventors: Charles E.

Patent number: 4161665Abstract: A sensor for engine vibrations at a predetermined frequency characteristic of detonation comprises a housing adapted at one axial end for attachment to an internal combustion engine, a magnetostrictive element axially compressed in said housing with a source of permanent magnetic flux and a pickup coil on a spool around the magnetostrictive element. The spool engages the magnetostrictive element in a force fit characterized by a predetermined push-out force. The sensor housing comprises a first resonant assembly having a first resonant frequency slightly higher than the predetermined frequency. The spool and coil are coupled to the magnetostrictive element by the force fit to comprise a second resonant assembly having a second resonant frequency slightly lower than the predetermined frequency. The overall output characteristic of the sensor thus has a single resonant peak at substantially the predetermined frequency.Type: GrantFiled: December 27, 1977Date of Patent: July 17, 1979Assignee: General Motors CorporationInventors: Charles E. Buck, James M. Johnson, Paul A. Joseph

Patent number: 4096735Abstract: A detonation sensor adapted for mounting on a vehicle engine component has a cylindrical outer case with an open end. An inner cylindrical case has an open end facing in the opposite direction as that of the outer case and is so disposed coaxially within the outer case that it is held slightly axially separated therefrom by at least one rod of a magnetostrictive material and a magnet axially in line therewith. The edges of the open end of the outer case are crimped over a washer which abuts the closed end of the inner case to exert an axial stress on the magnetostrictive rod. Axial mounting means are provided on the outer case; and a pickup coil surrounds the magnetostrictive rod within the inner case. Both inner and outer cases are formed from a magnetic material to shield the coil from external electromagnetic signals.Type: GrantFiled: September 1, 1977Date of Patent: June 27, 1978Assignee: General Motors CorporationInventors: Gerald O. Huntzinger, Charles E. Buck, Robert E. Campbell
