Abstract:
A water-sensing protection device for use with home appliances such as washing machines and dishwashers, incorporating a water-sensing probe that detects high water levels in a sink basin, wall discharge receiver or a stand pipe. The protection device also has a sensor that can be placed on the floor to detect the presence of water from the failure of the above-described appliances or the drainage system of the sink basin or the sink basin itself. The signal from the sensing probes may be used to deactivate the power to the appliance, resulting in the activation of an auditable alarm and warning light that a water overflow condition exists due to an obstruction in the drainage system, or the failure of the appliance or drainage system has occurred. An optional vibration sensor is also disclosed, since excessive vibration due to load imbalance could be indicative of a potential water problem.
Abstract:
The invention is an alignment device, method and system for use in conjunction with a conveyor system to assure the proper desired alignment and positioning of items being transported on a conveyor belt system in relation to the direction of travel of the said conveyor belt system. The said alignment device, method and system is comprised of a series of resistibly deflectable roller baffle assembly which are positioned along the sides of the said conveyor belt system, and extend pivotally over and into the path of travel of the said conveyor belt, but are deflected toward the edge of the said conveyor belt when contacted items on the conveyor belt, which baffles press against the edges of the items on the conveyor belt and thereby cause the rotational movement of the said items to the desired alignment and positioning. The said alignment device, method and system is particularly applicable to the handling of checked-in baggage in an airport security environment.
