Abstract: HIGH EFFICIENCY PUSH-PULL INVERTERS                  ABSTRACT OF THE DISCLOSURE            High efficiency push-pull inverters minimize undesirable energy losses usually resulting from simultaneous conduction and imperfect switching of the transistor switching means.  In each of the disclosed circuits, a saturable inductor and a diode are connected in parallel and across the base-emitter junction of each transistor.  Voltage on the base of each transistor  causes its associated saturable inductor to saturate, and the saturated inductor then terminates the flow of base current and provides a path for rapid evacuation of the charge carriers stored in the transistor base-emitter junction in order to render the transistor rapidly non-conductive.          Each diode provides a drain path for current continuing to flow through its associated saturable inductor after junction evacua-tion.  A novel triggering means initiates oscillation of the inverters.  Also disclosed are feedback means operable to prevent premature transistor conduction and a capacitor connected between the collectors of the inverter transistors operable to restrain the rate of change of transistor collector voltage, both of these features also serving to minimize energy dissipa-tion.

Abstract: Abstract of the Disclosure An improved liquid jet producing device for cleaning a swimming pool where the device is of the type which includes a housing located beneath the bottom surface of the pool and a mechanism for producing a liquid jet inserted in the housing. The mechanism includes a hollow plunger closed at the top capable of moving between open and closed positions in the housing.  The plunger is urged toward the closed position by a spring and includes an opening located so that it is blocked from the pool when the plunger is in the closed position and open to the pool when liquid introduced into the plunger over-comes the force of the spring and pushes the plunger toward the open position.  The plunger is turned between each movement between the open and closed positions for producing a jet which is capable of intermittently sweeping the pool through 360°. The improvement includes the housing including a solid bottom wall, a liquid inlet opening being located between the top and bottom of the housing, the bottom end of the plunger being located near the closed bottom of the housing when the plunger is in its closed position.  The plunger includes a plurality of openings along its length to allow liquid to enter the plunger from the inlet opening.

Abstract: ABSTRACT Disclosed is a clock recovery circuit which improves the S/N of recovered clocks and improves line efficiency.  The circuit comprises an oscillator having a frequency substantially equal to the clock frequencies of bursts issued by more than one station.  A phase difference detection circuit detects phase differences between the clock extracted from each of the bursts and the output from the oscillator.  An averaging circuit averages the phase differences detected during an interval designated by a first control signal. A memory circuit stores the averaged phase difference in response to a second control signal and reads out the stored phase difference in response to a third control signal.  A control circuit generates the first to third control signals in response to the output from the oscillator.  A phase shift circuit phase-shifts the output from the oscillator based on the phase difference read out from the memory circuit and thereby generates a recovery clock.  The clock of the first burst corresponding to the stored phase difference is used as the clock for a second burst from the station which is the same as the station of the first burst and occurring after at least one burst after said first burst.

Abstract: ABSTRACT A plurality of rotatable card holders are disposed end-to-end on a horizontal fixed shaft supported at its ends by a tubular frame.  Each of the card holders comprises two coaxial sections each of which is generally cylin-drical with a peripheral web for holding the cards. Each of the cards has two notches for receiving the webs of the card holder so as to mount the card removably and hingedly on the card holder.  At one end of each card holder there is provided a capstan having radially projecting spokes which extend out beyond the cards to provide means for manually rotating the card holder on the shaft.  Between the two sections of each card holder there is provided a brake device comprising two H-shape members disposed respectively on opposite sides of the shaft and connected by two screws.  The brake members have later-ally projecting flange portions which engage radial spoke-like webs of the card holder sections so as to cause the brake device to rotate with the card holder and narrower central portions which frictionally engage the shaft be-tween the two sections of the card holder.  The screws are rotatable by means of a screwdriver inserted between the two card holder sections to adjust the force with which the brake members grip the shaft so as to permit rotation of the card holder by the capstan and yet retain the card holder in whatever position it has been turned by the capstan.

HOUVIG              SENSOR OUTPUT CORRECTION CIRCUIT                          ABSTRACT   A sensor correction circuit uses a programmable read only memory (PROM) for storing characterizing information for an associated sensor or transducer.  The information is stored in the 1 x 2048 bit configuration.  The programmable read-only memory (PROM) has its parallel outputs connected to corresponding inputs of a 2048 bit shift register.  The programmable read-only memory and the shift register are located in an electronic circuit housing, along with a power supply and sensor signal handling electronics, attached to the sensor structure to form an integral package therewith.  An isolation interface is mounted on the housing and is connected between the circuit within the housing and an external data processing and interrogating system which may include a microprocessor.  The programmable read-only memory is used to store sensor characterizing information for providing sensor correction data to the microprocessor controlled data processing system and to supply this information upon demand by the data processing system to the shift register for read-out through the isolation interface to the interrogating data processing system.          The isolation interface may include signal isolators used to transmit the signals for controlling the programmable read-only memory and the shift register and for suppling power to the power supply to energize the shift register and the sensor signal handling electronics.
