An electronic control for an automatic filling beverage dispensing valve is shown. The dispensing valve includes a valve body, a flow control mechanism and a solenoid. The valve further includes an electrically conductive cup actuated lever for operating a micro-switch that is operatively connected to the electronic control of the present invention. The valve body includes a nozzle and a stainless steel electrical contact for providing electrical connection between the electronic control and the beverage as it flows through the nozzle into a cup. The electronic control of the present invention is microprocessor controlled and includes an internal signal generator which generates a signal independent of the input line frequency supplying the power to the control. This generated signal is buffered and applied to the dispensing cup lever while simultaneously being applied to a reference input of a phase-locked loop detector circuit. When beverage fills a cup to the rim thereof the beverage can flow over the rim and thereby provide an electrical continuity between the electrically conductive lever and the stainless steel contact within the nozzle.

In a large refrigeration system comprising a screw compressor of controllably variable output, compressor lubricating oil, discharged from the compressor in a mixture with compressed refrigerant, is separated from the refrigerant at an oil separator from which it is returned to the compressor. Compressed refrigerant flows from the separator, through a condenser, to a high pressure receiver, where it is held for circulation through an evaporator and thence back to the compressor. Through a bypass conduit in which a small liquid refrigerant pump is connected, condensed refrigerant from the receiver is delivered to a duct communicating the compressor discharge outlet with the oil separator inlet, to cool the oil-refrigerant mixture before it enters the separator. A thermostat senses temperature of that mixture near the separator inlet and so controls a throttling valve in the bypass conduit as to maintain that temperature substantially constant.

A method and apparatus for centrally controlling a hybrid furnace, heater, and boiler system installation which increases the operational cost efficiency of the hybrid installation by computing the operational efficiency and fuel costs of the individual furnace(s), heater(s), and boiler(s) and signaling the most advantageous choice. The apparatus may further embody thermostatic control functions.

A sensing system is disclosed. The sensing system includes a capacitive sensing pad comprising a first conductive layer and a second conductive layer. A clip is engageable with the pad and comprises a first conductor and a second conductor. The first conductor is configured to conductively engage the first conductive layer and the second conductor is configured to conductively engage the second conductive layer when the clip is engaged with the pad.
