  • Publication number: 20160081894
    Abstract: An alcohol based hand surgical scrub, which includes cationic anti-microbial agent preservatives, cationic polymer film-forming agents and a skin emollient, and provides a long term residual, anti-microbial “invisible glove” on the skin. The composition provides an immediate reduction in bacterial microbes. The polymer system creates an invisible film on the skin following solvent evaporation. This invisible film provides a lasting anti-microbial barrier on the skin which acts to prevent microbial growth.

  • Patent number: 8343525
    Abstract: An antiseptic cleaning agent, generally, comprising chlorhexidine acetate and a solvent, such as an alcohol and/or water. The chlorhexidine acetate acts as a highly effective biocide. Additionally, the chlorhexidine acetate allows the cleaning agent to dry without leaving a tacky residue. Where the cleaning agent comprises one or more alcohols, the alcohols may comprise any suitable alcohols, including lower alcohols having from 1 to 6 carbon atoms, such as ethanol and isopropanol. Where the ratio of ethanol to isopropanol may be from between about 1:1000 to about 1000:1. In addition to chlorhexidine acetate, the cleaning agent optionally comprises another non-alcohol biocide, such as triclosan. The cleaning agent can be used in any suitable manner. For instance, the cleaning agent may be impregnated in an absorbent material, such as a towelette, swabstick, or gauze. Additionally, the absorbent material may comprise a positively charged or a non-ionic substance, such as polypropylene or polyester.

  • Patent number: 4946107
    Abstract: An electromagnetically operable fuel injection valve for use with an internal combustion engine. The injection valve includes a non-magnetic housing having a fuel passage therethrough and a fixed magnetic core therein. A magnetic movable armature is floatably movable within a sleeve member within the housing. The movable armature has a nozzle portion of reduced diameter which carries at the exit end thereof a ball valve. A nozzle seat having a fuel discharge orifice is adapted for reception of the ball valve and means are provided for guiding said ball valve into sealing engagement with the discharge orifice.

  • Patent number: 4492210
    Abstract: A serviceable valve is provided for controlling the recirculation of exhaust gases within an internal combustion engine. The valve includes a housing having a first section provided with an interior chamber and a second section secured to and subtending said first section. A diaphragm is affixed to and interposed the housing sections and is in communication with the chamber. In response to a predetermined chamber pressure, the diaphragm is distorted in one direction from a predetermined rest position. The housing is mounted on a fitting, which subtend the housing second section, whereby said housing and the diaphragm are rotatable as a unit about an axis of the fitting to selected positions of adjustment. The fitting is removably mounted on the engine. Carried on the diaphragm is a stem assembly which is movable longitudinally in response to the distortion of the diaphragm. A portion of the stem assembly extends through and protrudes from the fitting and has a valve piece mounted thereon.
