Abstract: A beverage container pressurizer and more particularly to a screw threaded cap that replaces the screw threaded cap normally provided on large beverage containers and a manually operated reciprocating piston-type pump sealingly and releaseably connected with the screw threaded cap for pressurizing the beverage container to keep the carbonation suspended in a liquid state for sustaining the quality of a carbonated beverage for an extended life before "going flat". The replacement cap includes a valve assembly which permits entry of pressurized air from the pump but prevents egress of pressurized air from the container when the pump is removed. This arrangement enables a single pump to pressurize a number of beverage containers since the pump is separable from the replacement screw threaded cap which remains with the beverage container until all of the beverage has been consumed.

Abstract: A bio-medical injector apparatus comprising a base unit having a skin engaging portion disposed at an angular orientation with respect to the longitudinal axis of the base unit for supporting and maintaining a hypodermic needle at an optimum angular orientation for effecting an injection procedure, a carriage assembly reciprocally mounted on the base unit and carrying the hypodermic needle simultaneously therewith, a motor drive unit operably connected with the hypodermic needle for the preloading thereof with a suitable medication, a solenoid secured to the base unit and operably connected with the carriage assembly for a controlled reciprocation thereof for effecting the injection operation of the needle, and an electronic circuitry operably connected between a power supply and the motor drive and the solenoid for creating the logic necessary to perform the functions of the injector apparatus.
