Title: Hydro-massage tub control system
Inventor: RIST BRUNO A
IPC: A61H37/00
Filed: 1992-02-25
Abstract: HYDRO-MASSAGE TUB CONTROL SYSTEM     ABSTRACT OF THE DISCLOSURE    A control system for hydro-massage tub systems in which water is circulated through a pump and heater from the tub back to a plurality of jets in the tub to create a turbulent massaging action.  The system is comprised of an activating device, a pump, a switch activating circuit, a heater with proportional control and a water level sensing safety system.          The pump is controlled by a switching and timing circuit that limits the time the pump is on which is slaved to a heater control circuit to prevent operation of the heater unless the pump is circulating waker.  The proportional heater control circuit maintains the water temperature within a degree or two of a preset temperature by proportionally reducing power as the temperature approaches the preset limit.  The activating device transmits a signal to the switching and timer circuit when a mechanical plunger isolated from electrical circuits is operated.  The level sensing device monitors the water level in the tub and interrupts or prevents operation of the switching and timing circuit unless water is at a level which activates the level sensing signal transmission circuit.

Filed: 1992-06-30
Abstract: TAPE DUPLICATING SYSTEM                 Abstract of the Disclosure A master tape moves between first supply and take-up reels over a pinch roller.  A slave tape moves between second supply and take-up reels over a capstan.  First and second guides are respectively constructed and positioned to regulate the movement of the master and slave tapes to aligned positions on the pinch roller and the capstan.  A heater between the pinch roller and the second guide heats essentially only a thermomagnetic layer on the slave tape to at least the Curie temperature.  The heater is adjustably positioned to facilitate the movement of the slave tape to the aligned position on the capstan.  Brake shoes respectively between the first guide and the first supply reel, and between the second guide and the second supply reel, control master and slave tape tensions and damp any variations in tensions.          The pinch roller is movable to a first position, locked in position relative to the capstan, to abut the capstan and facilitate the transfer of magnetic information from the master tape to the slave tape.  In this disposition, the pinch roller locks the heater in a fixed position relative to the capstan.  The pinch roller and the associated guide are movable to a second position displaced from the capstan to facilitate the disposition of the master tape on the pinch roller.  The heater is pivotable relative to the capstan to facilitate the disposition of the slave tape on the capstan.          The rotational axis of the capstan, preferably of a unitary construction, is fixed.
