  • Patent number: 4706557
    Abstract: An improvement is made to continuous chip fryers by introducing means of control to the flow of oil in the fryer. The disclosure is most applicable to the type of fryers where heat is added externally in a separate heat exchanger. The controlled oil flow allows an increased loading of the fryer, thus reducing equipment size and oil resident time.

  • Patent number: 4237730
    Abstract: A fluid velocity measurement system includes a thermal generation means operated for short durations of time and disposed within a conduit suitable for guiding at least a portion of a fluid whose velocity is to be determined. Disposed downstream in the fluid guide means is at least one of a first and second thermal sensing means. The sensing means are spaced from each other. The first and second thermal sensing means are differentially coupled. The time period starting with the thermal generation means being turned on and heating a slug of fluid and extending to the generation of a differential electrical signal from the sensing means detecting the heated slug of fluid is the flight time of the heated slug of fluid. In one embodiment of the invention circuitry is provided to measure the actual flight time and divide it into a predetermined period of time resulting in a quotient which is proportional to the fluid velocity.

  • Patent number: 4219316
    Abstract: A pumping or compressing geometry is being disclosed. Several turns of deformable spiral are fitted in a curved housing to form line contacts between turns of the spiral by allowing it to bend. These line contacts separate the inlet and the outlet ports in a pump or form the compressing chamber in a compressor.
