Abstract: A pair of superimposed panels are heat sealed together to define a reservoir in a dispenser pouch, adapted to contain a liquid therein. A spout is formed in offset relationship on a lower end of the pouch and defines a charging chamber that communicates with the reservoir to retain a pre-measured charge of the liquid therein. The spout terminates at a normally closed valve that opens when a predetermined external and downward pumping pressure is applied to the spout. A retention band may be secured transversely across on outer side of one of the panels to retain the spout when it is reverse-bent and slipped thereunder. The pouch is adapted for mounting in a dispensing unit having a dual-action pressure plate for pumping and dispensing the pre-measured charge of liquid from the spout.

Abstract: A method and system for augmenting penile erection in a human male is disclosed. An inflatable cuff is placed circumferentially around the corpora carvernosa, the deep dorsal vein, and the cavernous veins, adjacent to the hilum of the penis. Selective compression of the cuff will function to restrict venous drainage to augment penile erection. The cuff is adapted to have opposite ends thereof attached together and at least one inflatable vesicle is formed on the inner side of the cuff. A pump, including an attandant control system, is sized for implantation in a scrotum whereby the pump can be selectively squeezed to inflate and fluid pressurize the vesicle to compress the cuff around the penis. A control circuit, connected between the cuff and the pump, functions to automatically deflate the cuff after a predetermined period of time has elapsed.

Abstract: Ion content of the atmosphere at a particular location is controlled by generating ions during repetitive period that are initiated by timing signals which reoccur at a predetermined rate. An ion sensor produces feedback signals indicative of the ion content of the air and a feedback circuit varies the duration of the recurring periods of ion generation, if necessary, to maintain the ion content within a predetermined range. Positive and negative ions may be generated during alternate ones of the repetitive periods in which case the feedback circuit inversely varies the periods of positive and negative ion generation to maintain the relative proportions of the two types of ion within a predetermined range. The method and apparatus may be used to suppress accumulation of electrostatic charge by objects, such as in a clean room where electronic components are manufactured, or for other purposes requiring control of the ion content of air.
