Abstract: ABSTRACT OF THE DISCLOSURE     This invention relates to a frequency converter for use in a receive-transmit ground station in a satellite communication system, having improved frequency control characteristics and reduced cost.  The converter is comprised of apparatus for generating a first local oscillator signal, and adding the first signal to a transmit baseband signal to form a first sum signal. A second local oscillator signal is generated, and the second signal is added to the first sum signal to form a second sum signal.  A third local oscillator signal is generated and the third signal is added to the second sum signal to form a third sum transmission frequency signal.  A signal is received at a receive frequency which is different from the transmit frequency, and the receive frequency signal is subtracted from the third local oscillator signal to form a first difference signal.  The second local oscillator signal is subtracted from the first difference signal to form a second difference signal, and the first local oscillator signal is added to the second difference signal to obtain a receive baseband signal.  The receive baseband signal includes a pilot frequency signal component.  It is preferred that the apparatus should include a filter for filtering the receive baseband signal to obtain a pilot frequency signal.  A reference oscillator having a normal frequency similar to that of the pilot frequency signal has its frequency compared with that of the pilot frequency in a frequency comparator and provides a control signal representative of the frequency difference, which is applied to the first or third local oscillator signal generator for controlling its frequency in response or frequency drift of the pilot frequency signal relative to that of the reference oscillator.

Abstract: MAGNETIC MEMBER DETECTOR WITH COMPENSATION FOR PROXIMATE FERROMAGNETIC MEMBER     ABSTRACT   A detector for detecting a moving ferromagnetic member irrespective of its speed. An output signal is produced by a bi-stable ferromagnetic device which is pulsed between its stable states in a zero flux field between the faces of pole pieces, when no member is present.  Moveable soft iron pole pieces are provided for convenient flux adjustment to compensate for flux distortion due to nearby magnetic structures. The presence of the moving ferromagnetic member introduces a net flux between the pole faces and terminates output signals. A timing circuit is provided to assure member presence before a signal is given and a further timing circuit assures that a member present signal is maintained for a predetermined minimum duration irrespective of member speed. A typical application is to detect wheels of a moving train.

Abstract: ABSTRACT       A liquifying pump includes two pairs of oppositly wound flights mounted on a rotatable shaft that acts as an impeller of the centrifugal pump with upper and lower orifices.   The impeller extends through these orifices to draw liquid-solid mixtures into the pump housing and for conveying the material out  of  the  housing  through  a  discharge  orifice  that communicates  into  a  downstream  conduit.    The  downstream conduit has a flow diverter for diverting the flow down to the ultimate discharge orifice of the conduit or back into the pool of solid-liquid materials so as to cause in this later condition circulation of the materials and hence to puree them.    This assists in breaking down the solid components therein so that the material that is to be pumped may be pumped  more  efficiently.    Such  pump  device  is  extremely convenient  for  pumping  and  conveying  a  liquid  manure.

Abstract: A ROTARY POSITIVE DISPLACEMENT MACHINE     Abstract of the Disclosure The invention concerns the formation of the high pressure port in a rotary, positive displacement ma-chine, such as a gas compressor, with an extension which is traversed by the plane on which the parallel axes of the rotors are commonly positioned.  A given portion of the port extension is constantly occluded by the gating rotor and, consequently does not add to the effective area of the port.  However, the remaining portion of the extension is exposed by the gating rotor, effectively defining a port opening which reaches to the common plane.  Thus, in gas compressor use of the machine, the port extension insures that all the com-pressed gas product is delivered through the exhaust port.

Abstract: ABSTRACT OF THE DISCLOSURE         Both a method of producing an image in accordance with an input signal having a location and brightness information and an apparatus for displaying such image are disclosed in the present application. The method comprises activating an energy source which emits photons in accordance with the brightness information of the input signal and processing the emitted photons for selected transmission along a predetermined path and in a manner to form a region of high photon energy at a location on the predetermined path in accordance with location information of the input signal.  This method can be enhanced by allowing for production of a coloured image when the input signal additionally includes colour information.  The colour is achieved by selectively passing the emitted photons through coloured filters in accordance with the colour information to thereby impart the colour.  The apparatus for reproducing an image in accordance with the input signal comprises a plurality of light conduits parallel to the screen which collectively define an area for displaying the image.  A light source is provided for the light conduits and the emitted light is processed for selective transmission in the light conduits having a brightness in accordance with the brightness information of the input signal and in a manner to produce regions of concentrated emitted light in the conduits in accordance with the location information.

Abstract: ABSTRACT OF THE DISCLOSURE          A rigid mount coupler in which all movement required for connecting and disconnecting the nipple occurs within the coupler housing.   A body member which receives the valved nipple  slides  within  the  housing  to  actuate a  locking mechanism to retain the nipple.  The body member supports the coupler valve in a spring loaded retainer so that coupler and nipple valves engage and are balanced in valve open positions.          A second spring loaded device supports the coupler valve at the  open  position  and  resists  further  opening movement, thereby preventing flow checking at the nipple.  Seals between the body member and housing isolate a stepped chamber there-between in fluid communication with an inner chamber closed by the coupler valve.  The volume of the stepped chamber changes upon movement of the body member and is dimensioned to corre-spond inversely to changes in volume of the inner chamber to prevent a fluid lock condition.

Abstract: LOOK-BACK DIGITAL-TO-ANALOG CONVERTER     ABSTRACT     In an analog-to-digital converter implemented in logic operating on the multiple lobes of a threshold curve, such as Josephson SQUIDs, two sampling registers are provided with sufficient offset to guarantee stability at sampling in one or the other regardless of other factors.  Knowledge of bit value of the next lower bit order position permits determination of which sampling is valid.  Encoder logic selects the valid sampling register retroactively.     Each sampling register bit order position has two sampling SQUIDs and latching self-gated ANDs.  Bias values are profided at higher orders to increment the phase offset so as to ensure low-to-high order readout.     The lowest two bit orders may be implemented in simplified logic, effectively giving two bit order positions for logic and SQUIDs equal to that of one higher order bit position.
