Abstract: The present application relates to devices for the vitrification of biological samples, including embryos, oocytes and biological tissues. Suitably, the devices are automated devices which require little if any operator intervention or sample handling, thereby reducing contamination, improving success rates and increasing efficiency. Also provided are methods of vitrifying a biological sample, suitably using the disclosed devices.

Abstract: This invention is a titanium plate developed for the temporary support of dental implant fixtures during alveolar ridge bone regeneration. When the alveolar ridge bone where the implant fixture is to be applied is very weak or damaged, this invention enables implant operation on the weak bone by temporarily supporting the implant fixture during the bone recovery time. This invention is characterized by a flat plane shape, a body section with one or more pass-through holes formed along its length, multiple arms extending from each side of the body section with a pass-through hole at the terminal of each arm for fixture to the alveolar ridge bone or facial bone with a micro screw. The body section is designed to be placed between the cover screw that passes through the hole and the implant fixture to hold the implant fixture firmly in place. The plate provides space for bone regeneration and can be readily removed after the completion of the implant-bone integration.

Abstract: Food Storage and Preservation System with a plurality of food storage containers each with a gasketed door, each the food storage container having an air inlet port and an air outlet port, the air outlet port terminating in a solenoid valve and a vacuum limit switch, a central air treatment module in a housing, the air treatment module consisting of a vacuum pump, an ozone generator, a microprocessor and a power supply, a wire and hose harness set, said wire and harness set capable of connecting said food storage container to said air treatment module, a switch sensor that activates when said container door opens or closes, a sliding food holding tray that resides inside said food storage container, a food storage and preservation system that, when the user closes said door, first ozonates the interior of said container and then evacuates the air from said container as controlled by said microprocessor, said evacuation automatically maintained by the monitoring of said vacuum limit switch, said air treatment

Abstract: A joystick device to be used in video games or the like having an improved construction to prolong the life of the switches used in the joystick device. The improved construction includes a conical spring located between a diaphragm and an actuator which reduces the force ultimately applied to the switches by the user of the video game. The actuator and the diaphragm surround portions of the shaft, and the actuator has a tapered inner wall which allows pivotal movement of the shaft which further reduces the force ultimately applied to the switches.

Abstract: This invention relates to water insoluble copolymer aqueous dispersions stabilized by multiple carboxylic acid functional comonomer residues against shear-induced coagulation. These copolymer dispersions are useful as pressure sensitive adhesives, and as binders for textiles, paper, non-woven materials, and coatings.

Abstract: Print pastes are thickened by a thickener concentrate containing about 5-50% by weight of a nonionic polyurethane having a molecular weight of at least 10,000 and at least 3 hydrophobic branching groups linked through hydrophilic polyether segments, a surfactant in an amount providing a thickener to surfactant weight ratio of about 1:0.01 to about 1:10, about 5-35% by weight of a non-aqueous organic diluent, and 0-65% by weight of water.

Abstract: Bis-ketimine esters of the general formula ##STR1## wherein, for example, R and R.sup.1 are alkyl groups,X is alkylene, andY is the non-carboxyl moiety of a dicarboxylic acid, are disclosed. Said compound is mixed with an acid polymeric anhydride to form an ambient moisture-curable adhesive composition.
