Abstract: The present invention relates to the removal of grease collected in a hydro-mechanical grease interceptor via a pump which may be activated by a programmable timer. In an embodiment, a hydro-mechanical grease interceptor includes a tank having a tank inlet and a tank outlet; a tray positioned inside the tank; and a pump located inside the tank, the pump having a pump inlet and a pump outlet, wherein the pump inlet is located within the tray at a level below the tank outlet. The interceptor may include a timer coupled to the pump to control operation of the pump.

Abstract: An interceptor for removing grease from an effluent stream containing grease and water may be queried remotely to check its status. An output signal indicative of the amount of grease is transmitted over a telephone line to a telephone or computer or other remote station, or wirelessly to a remote receiver. The status is preferably also indicated locally with visual and/or audible signals. The grease depth level sensor is preferably a capacitive level sensor operative to sense the amount of water in the body of effluent thereby to determine the amount of grease in the body of effluent. The interceptor may include electric circuitry for effecting manual or automatic calibration of the sensor. The sensor may be adapted to be retrofitted to an existing tank made from either metal or plastic.

Abstract: The present invention relates to apparatus for removing grease from an effluent stream containing grease and water. A separation tank defines a separation chamber. An effluent inlet connected with the separation tank permits flow of the effluent stream into the chamber to form a body of effluent in the separation chamber. A grease depth level sensor is used in determining the amount of grease in the body of effluent. The interceptor may be queried remotely to check its status. In one embodiment, an output signal indicative of the amount of grease is transmitted over a telephone line to a telephone or computer or other remote station. Alternatively, the output signal is transmitted wirelessly to a remote receiver. The status is preferably also indicated locally with visual and/or audible signals. The sensor is preferably a capacitive level sensor operative to sense the amount of water in the body of effluent thereby to determine the amount of grease in the body of effluent.

Abstract: A lock and release mechanism is disclosed which includes an elongated bendable member which engages a lock tab such that when the lock tab is disengaged with the chassis an electronics module can be moved into a plurality of positions, including a service position, a closed position and a removal position. Such a mechanism advantageously provides latch and release functionality using a single part.

Abstract: An apparatus for providing heat dissipation and electromagnetic shielding for an integrated circuit, such as a CPU, in a computer system includes a first surface thermally coupling the apparatus to an integrated circuit (IC). The apparatus, including the first surface, is of a material, such as some alloys of beryllium copper, with a yield strength of at least 80,000 pounds per square inch and with a thermal conductivity of at least 220 watts/meter*degree (Kelvin). The material is electrically conductive.
