  • Patent number: 5803227
    Abstract: An improved bill stacker is described that effectively rolls incoming bills onto the stack. In one aspect of the invention, the bill stacker includes a housing that encloses a stacking plate that is arranged to support a stack of bills. A gripper is typically provided to grab the leading edge of an incoming bill and a stack roller is arranged to travel longitudinally relative the stacking plate to "roll" a newly received bill onto a top end of the bill stack (if present) or the stacking plate when the first bill is being received. A variety of methods of stacking bills in a cash box using the concept of rolling an incoming bill onto the top of a stack are also described.

  • Patent number: 5350112
    Abstract: A tempered water mixing system for applications such as emergency drench shower and eyewash stations, wherein the mixing system includes back-up control valves to ensure a substantial water flow without risk of user scalding in the event of malfunction of a main thermostatic mixing valve. The main mixing valve thermostatically blends cold and hot water supplies to provide a tempered discharge outflow at a selected temperature. A temperature limit control valve detects the discharge outflow temperature and responds to an excess temperature condition to modulate hot water flow in a manner reducing discharge temperature. A flow limit control valve detects the pressure differential between the discharge outflow and the cold water supply, and responds to a low flow condition represented by a high pressure differential to permit a make-up bypass flow of cold water past the main mixing valve.

  • Patent number: 5008963
    Abstract: An improved emergency wash station is provided for flushing irritants from the eyes or face of an individual, particularly such as a person working in an industrial or laboratory environment. The wash station includes a spray manifold having a large plurality of spray ports disposed above the upper rim of a drain bowl, with the spray manifold being connected to a water supply via a single inlet fitting located externally of the drain bowl. A pressure control member at the inlet fitting insures a relatively gentle yet substantially full face flush spray throughout a range of water supply pressures. In addition, the spray ports are formed with an outwardly expanding taper to minimize clogging by ice or other debris.
