Abstract: A solid state, static power supply control mechanism for coordinated transfer of a load from a preferred source of AC power to an alternate source of AC power should the level of power transmitted from the preferred source fall below a set, adjustable level and thereafter, upon re-establishment of the proper level of operating power of the preferred source, re-transfer of the load from the alternate source to the preferred source. A unique method of current interlock prevents the alternate power source from connecting to the load until the current from the preferred source is absolutely interrupted, with the same criteria required for re-transfer from the alternate to the preferred source of power. This mechanism and associated switching technique insures supply of power to the load regardless of the preferred power source failure mode and regardless of the phase relation of the preferred and alternate sources of power.

Abstract: A meter for determining flow rates and total volume of fluids normally mixed with a gas and delivered with a pulsating rather than a uniform flow rate, such as milk being delivered from a milking machine. The unit includes a housing having an upper, baffled, receiving chamber which initially reduces flow velocity and a second, lower chamber, having baffles or weirs for turbulence reduction prior to passage of the fluid through a particularly designed, double tapered orifice, to a measuring chamber. Within the second chamber, air and foam is separated from the milk prior to flow measurment. A plurality of electrically operated, vertically arranged probes are provided within the measuring chamber and these probes are rapidly monitored to determine the level of milk as passed through the orifice. The pulsating but relatively laminar flow causes the liquid level to oscillate between probes and the processing of the rapidly scanned probes provides data to determine the true flow rate.

Abstract: A camera system for the simultaneous and substantially exact capturing of images of a subject on separate image reproduction mediums wherein an optical member is interposed between a lens group and a pair of separate, discrete image receiving mediums. One of the mediums is a photographic film and the other is a viewing screen for personal viewing or, alternatively, an electronic system for electronic signal generation, electronic viewing and electronic capture of the image. The optical member allows light rays emanating from the object to pass therethrough to impinge upon one of the mediums while simultaneously reflecting light rays to the second medium. This system allows for the simultaneous transfer and reproduction of the object image onto more than one medium without degradation of the image or depth of field. The system accomplishes the multiple image transfer through a stationary device, thereby eliminating the necessity of moving parts.
