Abstract: A circuit for providing an adjustable period of delay in a vehicle which is started by engaging the engine of the vehicle and a brake means, then disengaging the brake means after the period of delay, has a relay for selectively engaging and disengaging the brake. A variable time delay provides the period of delay. A switch selectively causes the relay to engage the brake and then to disengage the brake after the period of delay. A safety activation means prevents the relay from engaging the brake means in the absence of the switch selected to cause the relay to engage the brake means.

Abstract: A control system for automatically maintaining a predetermined water level in a swimming pool includes a multi-contact water level sensor unit mounted on an exposed sidewall of the pool. The sensor unit is vertically adjustable within a stationary mounting bracket to enable user adjustment of a selected normal water level. A single sensing contact on the sensor unit senses the presence or absence of water at the selected normal level. A monitoring circuit associated with the sensor unit interrupts operation of the control system in the event that the sensor unit is disconnected. Additional water level sensing contacts open a dump valve to preclude overflow of the pool in the event of a high water condition, and interrupt operation of recirculation pump apparatus associated with the pool in the event of a low water level.

Abstract: The invention concerns a system for keeping windshield wiper blades free of ice or snow accumulation. A rectangular strip of transparent material is either affixed to or formed integrally with the windshield to extend outwardly from the surface thereof for a distance of 1/16". The strip is about the same length as the wiper blade and one inch wide. It is positioned with the longitudinal edges parallel to and the lower edge spaced 2" from the rest position of the wiper blade, whereby the blade wipes over both longitudinal edges of the strip in each direction on every cycle of reciprocating blade movement. The dimensions of 1/16" in thickness, 1" in width, and 2" spacing from the blade have been found to provide superior results in optimum blade cleaning with minimal wear on the blade edges, and are therefore considered critical dimensions.
