Abstract: This invention relates to a hot water system which utilizes heat from the refrigerant of a refrigeration system to produce hot water. A condenser as part of the hot water system is especially designed with greater heat exchange surface than would normally be provided with the refrigeration system so that water at convection flow and at a higher temperature than normal can be used in the condensing unit and yet achieve the necessary absorption of heat from the refrigerant passing through the condenser as required for proper operation of the refrigeration system.In one embodiment of the condenser unit a de-superheating coil is located at the top of the housing to overlie the top of an inverted can arrangement within the housing. Between the sides of the housing and the inverted can is located a sheet type heat exchange surface which is preferably pillowed.

Abstract: A massage unit used for therapeutic purposes such as to loosen and mobilize bronchial secretions in humans; to improve blood circulation, and; to relax muscles, has a motor unit which transmits rotary motion to a cable engaged to an applicator unit. The applicator unit has a lower gripping portion which rotatably mounts an eccentric drive assembly which is drivingly coupled to the cable so as to be oscillated by cable rotation. An elbow-shaped tube extends upwardly and outwardly from the eccentric assembly so that an application pad mounted on the outer end of the elbow is moved in a circular path around an axis extending parallel to the surface of a patient's body and also parallel to the surface of an application pad, which allows the pad to impart a percussive and a directional massage stroke when it is applied to the body.
