Abstract: ABSTRACT OF THE DISCLOSURE            A power saving circuit for a gaseous discharge lamp includes a power circuit and a control circuit.  The power circuit is connectable to an AC power supply and to at least one lamp and has a bilateral current conducting power switch with control electrode means.  The control circuit has a control switch with control electrode means, and timing means operable to apply a signal to the control electrode means of the control switch to render the control switch conducting at a predetermined time during each half cycle of the AC power supply, the control switch conducting current until zero crossover at the end of each half cycle.  Opto-coupler means are associated with the control switch on the one hand and with the control electrode means of the power switch on the other hand to cause actuation of the control electrode means of the power switch and subsequent current conduction by the power switch when the control switch is conducting.  The control electrode means of the power switch is connected through the opto-coupler means to the power circuit to cause, while the opto-coupler means is actuated by current conduction  through the control switch, adequate power switch actuating current to flow therethrough when the power switch is not conducting and substantially re-duced or no current to flow therethrough when the power switch is conducting.

Abstract: GEROTOR GEAR SET DEVICE WITH INTEGRAL, ROTOR AND COMMUTATOR                         Abstract A hydraulic device with fluid pockets formed by a gerotor gear set, including a rotatable and orbital rotor, has a special commutation valve structure for valving fluid flow to and from the fluid pockets in timed relation to the movement of the rotor.  The gear set is disposed between a pair of housing members.  One end face of the rotor and the face of the adjacent housing member cooperate to define separate pressure areas which are continuously communicated with high and low fluid pressures, respectively.  The other end face of the rotor has a circular array of openings which number twice the number of teeth of the rotor.  A series of passages extending through the rotor communicate all of the openings of the circular array with the separate pressure areas, alternate openings being communicated with areas at different pressures.  The face of the housing member adjacent the other end face of the rotor has radially extending, generally T-shaped recesses facing the fluid pockets.  The circular array of openings in the rotor and the recesses in the housing member cooperate to valve flow and direct flow to and from the pockets at the interface of the rotor and housing member as the rotor rotates and orbits.

Abstract: Case 5066 ABSTRACT OF THE DISCLOSURE         IMPROVED METHOD OF PRODUCING ETHANOL-WATER               AZEOTROPE FROM CRUDE ETHANOL    This invention relates to a process for purifying crude ethanol, whether produced by fermentation or by the synthetic route, to produce a pure ethanol-water azeotrope.  The process uses only two distillation columns for fermentation ethanol or synthetic ethanol eventhough the latter has diethyl ether as impurity.  The inventive concept lies in the design and specification of the columns and the specific high pressure and low reflux ratio distillation conditions which enable each of the impurities in ethanol to be reduced below ppm.  Ethanol of such purity is most desirable when used for potable or pharmaceutical purposes.

Abstract: A B S T R A C T            A frame recovery circuit for a pulse code multiplexed signal receiver is provided.  Simple and reliable decoding of T-1 type pulse code information is achieved by combining a fast-acting recirculating frame recovery circuit with a simplified signal output register. The frame re-covery circuit uses a recirculating 386-bit control word in which all positions which cannot be the main-frame bit position are continuously recorded by the continuous comparison of pairs of incoming data bits spaced 386 bits apart.          Following a sufficient number of  iterations of the control word to statistically identify all 385 non-main-frame-bit positions with a high degree of probability, the remaining unidentified position is read out as the main-frame bit position, and is used to reset the frame clock generator.
