Abstract: RCA 71,140 WIDEBAND ELECTROMECHANICAL RECORDING SYSTEM                 Abstract of the Disclosure A system for recording signals in a disc master comprises an electromechanical cutterhead responsive to the signals and a signal processing means interposed between the cutterhead and a signal source.  The signals applied to the cutterhead are of the encoded type such that most of the signal energy is contained in signal components occupying a band of frequencies about one octave wide or less. The cutterhead is so constructed that its response to the signal components varies with frequency in substantial correspondence with the energy distribution of the maximum signal components over the afore-mentioned band.  The signal processing means serves dual purposes.  On the one hand, it cooperates with the cutterhead to provide a combined frequency response which is relatively uniform.  On the other hand, it serves to reduce the energy level of high energy level signal components applied to the cutterhead.  The reduction of the applied energy makes possible the use of a smaller cutterhead than would otherwise be the case.  The smaller cutterhead structure, in turn, results in a relatively wide cutterhead bandwidth.

Abstract: METHOD AND APPARATUS FOR KNITTING SLIVER LOOP KNIT FABRIC, AND THE RESULTING PRODUCT                              Abstract A sliver loop knit fabric comprising a base fabric formed of knitted courses and wales and anchoring a plurality of tufts of sliver fibers, the free ends of which are incor-porated into at least two courses and two wales of the fabric to provide a generally loop pile fabric.  The fabric is knit on a circular jersey fabric knitter equipped with a plurality of fiber feeding cards.  The knitter also is equipped with pneumatic means for directing jets of compressed air generally radially outward of the needles of the knitting machine.  The jets of compressed air blow the free ends of the tufts of sliver fibers on the needles outwardly of the needle circle, and onto the tops of the sinkers, preparatory to incorporating the ends of the tufts into the fabric during knitting.  The bulk of the free ends are incorporated into the fabric in the form of knitted stitches.  Stray ends or "tailings" of the tufts are pushed back between the needles inwardly of the needle circle by reciprocal sinkers, whereby those ends are interlaced about the needles preparatory to their interlace-ment in the form of floats into plural courses and wales of the fabric.

Abstract: ABSTRACT OF THE INVENTION Circuitry directed to the rapid de-ionization of ultraviolet detectors by increasing the mobility of the ionized gases within the tubes which will enable the tubes to more effectively operate at low temperatures. The circuitry includes connecting circuitry for shorting the elements of the tube such that they will be at the same potential immediately after firing and also includes circuitry for the shunting of the tube immediately after firing to limit the number of ions generated in the discharge process.  The shorting of the elements increases the surface area of negative electrodes for the recapture of the ions and the distance through which the ions must travel is reduced by a factor of one-half.

Abstract: Case 22 - Svala ENCODER/DECODER SYSTEM EMPLOYING    PULSE CODE MODULATION     Abstract A codec is disclosed for encoding analog signals into compressed PCM (CPCM) and conversely for decoding CPCM information into analog signals.  The signal to be encoded is compared with the decaying voltage on a capaci-tor, initially charged to a fixed voltage E, and being discharged through a fixed resistor to another fixed voltage - dE, the time being measured by a binary digital counter from the start of the discharge until the voltage  at the capacitor terminal equals the absolute value of the analog signal to be encoded.  With proper choice of constants and clock frequency, the content of the binary counter at the time of coincidence represents the desired pulse code in complementary binary form of the analog signal sample to be encoded.  Only the sign bit has to be added, which can be easily obtained from the polarity of the signal sample.  Conversely, at the receiving end, the CPCM signal may be decoded into analog signal samples by timing the discharge of a similar or identical RC-circuit in accordance with the received code.

A sidewall blank feeder sequentially feeds blanks to the mandrels before each respective mandrel moves into a wrapping station wherein the sidewall blank is wrapped about the respec-tive mandrel. The mandrel having a wrapped sidewall then moves to a station for receiving a formed bottom closure member after which the bottom closure member and the sidewall carried by the respective mandrel are moved to a sta-tion for heating a portion of the bottom closure member and the sidewall blank. After passing through the heating station the mandrel carrying the sidewall blank and bottom closure member moves through a bottom crimping station wherein a portion of the bottom closure member is bonded to a portion of the sidewall blank to form a container. After passing through the crimping station, the mandrel carrying the container moves to a finishing station which is operable for finishing the open end of the container and then removing the container from the mandrel. A conveying means is also provided for carrying the finished container away from the finishing station. The stripped mandrel then returns to pick up a new sidewall blank.

Abstract: ABSTRACT OF THE DISCLOSURE     Disclosed is a digital multifrequency signalling receiving system in which a first operation device executes an operation to multiply multifrequency signals composed of N samples as input signals by a window function including co-efficients required for fast Fourier transformation.  An out-put produced at the first operation device, as a sample signal, is subjected to fast Fourier transformation at a second operation device which includes a subtractor and a logic circuit.  In the subtractor, the sample signals are delayed ? samples to halve the number of sample signals.  The logic circuit executes an operation for the sample signals, taking advantage of the fact that some frequencies of the outputs of the Fourier transformation are represented as the conjugate complex of the other outputs of the Fourier transformation.          The sample signals fast-Fourier-transformed and produced at the second operation device are subjected  to discrete Fourier transformation in a processor, where an output for detecting the multifrequency signals is obtained.            .
