Abstract: Abstract A frequency synthesized transceiver capable of tuning to a plurality of communication channels is disclosed. The transceiver includes a receiver section and a transmitter section which are coupled to the synthesizer which generates the appropriate injection signals to achieve tuning. The frequency synthesizer includes a multiposition switch which accesses various addressable memory locations in a programmable read-only memory where the appropriate divisors are stored to cause tuning of the synthesizer to the appropriate communi-cation channel.  A zone selector switch enables grouping and easy retrievability of channels.  The divisors are supplied to a single synchronous binary swallow counter which works in conjunction with a dual modulus prescaler to monitor the frequency output of the voltage controlled oscillator.  A programmable divider coupled to a reference oscillator source is compared with the output of the synchronous counter in a digital and analog phase detector.  The phase detector supplies signals through loop filter to apply the appropriate voltage to the voltage controlled oscillator. The phase detector effects rapid advance of the voltage controlled oscillator to cause frequency tuning.

Abstract: Abstract of the Disclosure A stud driver for  the insertion of studs into a work-piece.   The stud driver automatically grasps the stud once the stud is inserted into the stud driver. Once the stud is inserted into the workpiece, the stud driver automatically releases the stud.  The stud driver employs a set of jaws to grasp the stud.          The jaws, which are biased open by a plunger means, are enclosed with a carriage.   In the peripheral wall of the carriage,  two sets of balls are held.  The balls prevent the jaws from sliding out of the carriage  and  from  rotating in the  carriage.   The carriage  is driven by a driven head which is connected to the driving means. The carriage and driven head are held in an un-complicated hollow cylinder which is the body.   Grooves in the faces of the jaws cooperate with the balls and allow Q limited amount of reciprocation of the jaws within the carriage.  Move-ment of  the carriage within the body is not essential,  so that the body serves to hold the balls in the carriage and to provide structural support.

Abstract: ABSTRACT OF THE DISCLOSURE      A series inverter, high voltage capacitor charging circuit includes current sensors for sensing the current through each SCR in the cir-cuit.  The sensed current is used to vary the gat-ing frequency of the SCRs and to preclude firing of an SCR until the other is in a stable off con-dition.  The gating of each SCR is delayed by an amount of time determined by a control capacitor charging circuit.  That charging circuit is inhib-ited as long as one of the SCRs is conducting and once the load voltage has reached a predetermined level.  The time constant of that charging circuit can be changed as the desired level is approached.

Abstract: ABSTRACT OF THE DISCLOSURE     An AGC gate signal generating circuit for a television receiver comprises a series RC circuit having a time constant for developing a charging current at a relatively slow rate in relation to a horizontal scanning line of a video signal and at a relatively fast rate in relation to a field of the video signal.  The AGC gate signal is developed at the collector of a transistor whose base is coupled for receiving the video signal and whose emitter is coupled to the node formed between the resistor and capacitor of the RC circuit.  The transistor is responsive to a nominal level video signal for assuming a non-conductive state during horizontal scanning lines for charging the capacitor to a level below the video black level and for assuming a conductive state during horizontal sync intervals for discharging the capacitor to produce the collector current AGC gate signal. The transistor further assumes a conductive state for producing the AGC gate signal in response to a number of horizontal scanning liens of a reduced level video signal substantially less than a full field.
