Abstract: ABSTRACT OF THE DISCLOSURE     In a straight side press having a bed, a reciprocal slide, a power drive for the slide and apparatus for feeding a stock strip into the dies, the improvement of modifying the press to function as a transfer press by replacing the conventional die set with a plurality of longitudinally spaced sequential dies upon a die shoe secured to the bed to define a series of stations. A plurality of corresponding sequential punches are mounted upon a die shoe secured to the slide, and a pair of slide bars are reciprocally mounted upon the bed outwardly of the dies mounting pairs of opposed workpiece gripping fingers adapted for engagement with the respective workpieces at each station. A slide bar translator is mounted upon a sub-plate and has a reciprocal end plate connected to the slide bars for transferring the workpieces from station to station. The translator is adapted for alternately moving the slide bars towards and away from each other.

Abstract: OXIDE ISOLATION PROCESS FOR STANDARD RAM/PROM                AND LATERAL PNP CELL RAM     ABSTRACT An oxide-isolated RAM and PROM process is disclosed wherein a RAM cir-cuit includes a lateral PNP transistor formed in the same island of silicon material as a vertical NPN device and further wherein contact is made to the base of the lateral PNP and to the collector of the vertical NPN through a buried contact region accessed through a sink region formed in an adjacent island of semiconductor material.  A field implantation beneath the isolation oxide avoids implanting impurity along the sidewalls of the semiconductor mate-rial adjacent the field oxidation and therefore provides both vertical and lateral isolation from one silicon island to another.  Substantial reductions in sink sizes and cell sizes are obtained by eliminating the field diffusions from the sidewalls of the semiconductor islands.  The lateral PNP transistor serves as an active load for a memory circuit constructed using the structure of this invention.  The process also can be used to manufacture PROMs from vertical NPN transistors.  An LVCEO implant is used to increase the breakdown voltage of each vertical transistor from its collector-to-emitter thereby allow-ing junction avalanching of selected emitter-base junctions to program selected PROMs in the array even though the programming voltage is only a few volts beneath the breakdown voltage of the oxide isolated structure.

Abstract: ABSTRACT OF THE DISCLOSURE     Dental bridge or crown caps are removed by drilling a hole in the crown for inserting the end of a bolt to contact the tooth stub.  The bolt is in a metal stabiliz-ing bar member which rests in balanced and aligned position upon the cap structure and is connected thereto as a unit that moves together by means of wire or equivalent flexible means wrapped thereabout and tight-ened so that the bolt pressure on the tooth stub will apically lift the crown without shear stresses.  A porcelain crown is non-destructively removed by exerting an upward force on a noose about the neck of the crown from a balanced bar-body resting on the tooth by means of a screw threaded through the bar-body.  Balancing is achieved by connecting the noose to the bar-body with a plurality of special straps spaced about the crow circumference and passed over pegs on which cylindrical bushings of various diameters may be placed for changing the effective lengths of the straps.  Special light-weight tooling is made feasible for tightening the noose about the crown and clamping it in place so that hands are freed to thereby effect a simpler more efficient crown removal process.

Abstract: CONTROL CIRCUIT FOR A SOLENOID     DRIVER FOR A DISPENSER          ABSTRACT OF THE DISCLOSURE         A control circuit for a solenoid driver for a dis-penser having inherent pull-in and drop-out delays.  The circuit includes a tachometer that generates pulses representative of the speed of a conveyor that conveys a substrate upon which the dispenser dispenses fluid.  A sensor generates a trigger signal indicating that the substrate is at a preselected location.          Delay counter circuitry, enabled through the trigger signal, generates an enabling signal after receiving a preselected number of pulses.  Duration counter circuitry, enabled by the enabling signal, generates an initial driving signal of a pre-selected signal duration.  Compensator circuitry receives the initial driving signal and modifies it so as to compensate for the pull-in and drop-out delays so that fluid is deposited for the dispensing duration upon the substrate commencing at the preselected position.

Abstract: ABSTRACT This concerns a circuit for generating a desired two terminal impedance at two terminals which involves guiding analog signals appearing at the two terminals into an analog digital converter, supplying the output there-from to a digital processing circuit, leading the outputs therefrom to a digital analog converter, and connecting the output therefrom to the two terminals to form a feed-back loop, so that the digital processing circuit processes with a desired transfer function.  The circuit of the invention is characterized in that an analog processing circuit is provided which receives the analog signals appearing at the two terminals as input and which passes frequencies higher than the frequencies processed in the digital processing circuit.  The output of the analog processing circuit is connected to the two terminals to form another feed-back loop, and the higher frequency is led to pass through the analog processing circuit instead of the digital processing circuit to lower the frequencies to be processed in the digital processing circuit, thus permitting use of a less costly digital processing circuit.

Abstract: PERFORATED PITA BREAD       Abstract After pita dough has been rolled and prior to baking of  the dough  to form pita bread,  the flat pancake-like dough form is weakened along a perforation or score line on at least one side of the dough form.   In the baking process  the dough  form seals  and  inflates  to form the central   void   characteristic   of   pita  bread. The perforation or score line forms a weakened section in the inflated skin of the baking dough so that the rupture of the   pita   skin   during   the   baking  process   occurs preferentially at the perforation or score line.  The pita bread which results  from this baking process is easily torn  at  the  perforation  or  score  line.    Since  the perforations cause the baking-caused rupture to be located at the tear line, the pocket formed by the pita bread when it  is  torn  and  opened by  the user  will not include a baking-caused rupture.

Abstract: SIMULTANEOUS TRANSMISSION OF SPEECH AND DATA OVER                     AN ANALOG CHANNEL            Abstract The present invention relates to a technique for transmitting an entire analog speech signal and a modulated data signal over a transmission channel such as a common analog telephone speech channel.  The present technique multiplexes the entire modulated data signal within the normal analog speech signal frequency band where the speech is present and its signal power density characteristic is at a low level.  Separation of the speech and data signals at the receiver is effected by recovering the modulation carrier frequency and demodulating the received signal to recover the data signal.  The data signal is then remodulated with the recovered carrier and is convolved with an arbitrary channel impulse response in an adaptive filter whose output signal is subtracted from the received composite data and speech signal to generate the recovered speech signal.  To improve the recovered speech signal, a least mean square algorithm is used to update the arbitrary channel impulse response output signal of the adaptive filter.
