Abstract: A self-disinfecting drain trap system designed to automatically clean and disinfect drain traps in drainage channels. Cleaning and disinfection occur automatically during normal usage without interrupting the functions of the drainage trap. The new drain trap works according to a novel combination of electromechanical oscillation, preferably ultrasound, heating of the interio r of the drain trap and sealing liquid, and prevention of fouling on the inner wall by means of an effective antifouling antimicrobial coating. The risk of aftergrowth on sanitary equipment, fittings and in ambient air due to micro- organisms from drainage channels is thus effectively combated.

Title: Method for producing aqueous resin dispersion composition
Inventor: SANAI YASUYUKI
IPC: C08F2/26
Filed: 2000-07-06
Granted: 2010-05-11
Abstract: A method for producing a stable aqueous resin dispersion composition. In the method, a monomer mixture containing a carboxyl monomer having a carboxyl group and a hydrophobic monomer is first prepared. The monomer mixture contains 10 to 75% by mole of the carboxyl monomer. Then, the monomer mixture is subjected to radical polymerization at 180 to 350°C to produce a macromonomer. The macromonomer is neutralized. The neutralized macromonomer has an ethylenically unsaturated bond at least at one end. Using the neutralized macromonomer as an emulsifier, a vinyl monomer is subjected to emulsion polymerization in an aqueous solvent. Thus, a substantially uniform aqueous resin dispersion composition is produced. Even when a solvent is added to this aqueous resin dispersion composition, the emulsion state of the dispersion is maintained.

Abstract: A tibia fixturing device comprises a metal tray formed with annularly spaced recesses in its underside at a depth of at least about 1.5 mm and from which a stem depends for axial insertion into a tibia conical cavity. The stem has a circular cylindrical portion proximal the tray and a conical portion distal the tray. Fins radially extend from the stem cylindrical portion and penetrate the tibia to provide some torsional resistance. Axially extending channels are formed about the stem periphery which channels have bottom surfaces parallel to the stem axis to provide further torsional resistance. The channels are arranged to not interlock with the cement in the axial direction to permit the cement to separate first from the device during axial removal of the device from the bone. The fins have inclined edges distal the tray and inclined radial outer edges to align and center the stem to the bone cavity edge. Cement in the tray recesses bends the tray to a tibia resected surface to provide major torsional resistance of the tray about the cavity longitudinal axis.

Abstract: A drive mechanism (20) for delivery of infusion medium including an electrically coil (38). The coil (38) surrounds a piston channel (35) extending in an axial direction. The piston channel (35) provides a passage for communication of infusion medium to an outlet chamber located at one end of the piston channel (35). A piston (44) is located within the piston channel (35) and is moveable axially within the channel (35) to a forward position, in response to movement of an armature (42) to its forward position. The armature (42) and piston (44) are moved toward retracted position, when the coil (38) is not energized. In the retracted position of the piston (44), a piston chamber (65) is formed. As the piston (44) is moved to its forward position, the piston chamber (65) volume is reduced and pressure increased to move a valve member (66) into an open position.
