Abstract: ABSTRACT      A portable duplex radio telephone system includes base station transmitters having a predetermined base transmission range, and a plurality of portable or mobile units each having a predetermined maximum transmission range shorter than the base transmission range.  Satellite receivers are deployed about each base station for receiving transmissions from the portable units.  The base station transmitters transmit signals on a signalling channel and on at least one communications channel.  The portable receivers have means for scanning the base station transmitter signalling frequencies and for tuning to the signalling frequency associated with the strongest signalling signal received from the base transmitter.          When communication is initiated, the portable transmitter and receiver are automatically retuned to one of the communications channels as determined by the strongest received signalling frequency and by channel availability.  Means are also pro vided to continuously locate a portable unit and switch the operating frequency thereof as the portable unit moves between base station transmitter coverage areas.  Further means are provided to reduce the output power of each portable transmitter to the minimum satisfactory level in order to reduce battery drain and interference.

Abstract: ABSTRACT OF THE INVENTION           The present invention relates to a solid state imaging system in which pattern noise is cancelled both] electrically and visually.  Pattern noise takes the form of a succession of variable amplitude pulses occurring as each light sensing element in a row of elements is read out.  The pattern noise is duplicated from row to row. Since pattern noise is initially many times larger than the video signal, it must be reduced to a fraction of the video signal for satisfactory imager operation. In accordance with the invention. a first video signal is formed in which each row of sensors is first scanned with video and pattern noise present followed by a second scanning with video absent and pattern noise present. The first video signal, delayed one hoirzontal line, is then combined subtractively with an undelayed first video signal to form a second video signal in which the video information in the first member of the line pair is of one polarity and of opposite polarity in the second member while the pattern noise is cancelled to a small residue of like polarity in both members of the line pair.  A Third video signal is formed with the video in each line pair of like polarity and the pattern noise residues of opposite polarity.  The third video signal is now in a form suitable for visual cancellation of the pattern noise residues.  This is accomplished by causing the third video signal to be displayed with the pattern noise of one polarity on odd lines of the monitor and of opposite polarity on even lines of the monitor.

Abstract: ABSTRACT OF THE DISCLOSURE         In accordance with the present invention, there is provided herein improved glass fiber dispersions for making uniform glass fiber mats by the wet-laid process.  The well dispersed glass fiber compositions of this invention usually are prepared by mixing chopped glass fibers in water with a small amount of a select group of cationic quaternary ammonium compounds which have at least two long chain groups as part of the molecule.  As features of the invention, the dispersions may be formed at relatively high glass fiber consistencies, in neutral or slightly alkaline solutions, and without generation of a high degree of foams.  The resultant dispersions then are used to make very high quality glass fiber mats at high rates of production.

Abstract: TITLE:  TOY VEHICLE HAVING REVERSING MECHANISM      ABSTRACT           A toy vehicle having a base section and a turret section is movably supported on a plurality of wheels. Located in the interior of the vehicle is a motor which is suitably connected to at least one of the wheels of the vehicle.  Included in the connecting mechanism between the motor and the wheels is a reversing mechanism for reversing the direction of rotation of the driving of the wheels and thus the direction of the travel of the vehicle.  The reversing mechanism also incorporated a trip switch having a position corresponding to movement of the vehicle in one direction and a second position corresponding to movement of the vehicle in the other direction.  The trip mechanism is tripped by an outside stimulus, e.g. a metal ball. Operatively connected to the trip mechanism is an exposure mechanism which alternately extends and then retracts a portion of the trip mechanism in and out of the body of the vehicle.  This results in the trip mechanism only being exposed to the outside stimulus when the trip mech-anism is extended outside of the body of the vehicle. The vehicle can also include an indicating mechanism which in-dicates the status of the trip mechanism, that is it would tell an observer whether or not the trip mechanism is exposed from the vehicle body and thus whether or not the direction of the vehicle can be reversed.

Abstract: ABSTRACT OF THE DISCLOSURE     The present invention relates to a shock absorbing apparatus for connection in a drilling string and capable of transmitting the axial drilling work loads and the torsional forces required for rotating a drill bit at the bottom of the drill string.  The apparatus includes an elongated housing and a mandrel extending longitudinally within the housing. The housing interior and the mandrel have mutually co-operating formations thereon for transmitting the axial and torsional forces.  The mutually co-operating formations have substantial clearance spaces therebetween such that the mandrel has a substantial degree of axial and torsional freedom relative to said housing.  A matrix of resiliently deformable material is disposed in the clearance spaces between the mutually co-operating formations so that under the influence of shock loadings on the drill string, the matrix of material deforms and flows to take up and reduce the shocks and vibrations transmitted between the mandrel and the housing.

Abstract: FLOW DEVICE AND METHOD          Abstract of the Disclosure A flow device and method delivers a gaseous medium to utilization equipment having variable pressure conditions at its intake.  A gaseous medium intake zone connects with structure defining a variable area throat zone for con-stricting the flow of the gaseous medium to increase the velocity thereof to sonic.  The throat zone is adjustably varied in correlation with operating demands imposed upon the utilization equipment.  Wall structure downstream from the throat zone provides a gradually diverging zone for efficiently recovering the kinetic energy of the high velocity gaseous medium as static pressure.  Through such efficient recovery the velocity of gaseous medium through the throat zone is sonic over a wide range of pressure conditions at the intake of the utilization equipment.  A flow splitter is spaced from the adjustable throat zone and the splitter is arranged to divide the downstream end portion of gradually diverging zone into multiple zones of reduced divergence.  The multiple zones have reduced divergence compared to the divergence of the upstream end portion of the gradually diverging zone and also the down-stream end portion if the splitter were not present.
