Abstract: PULSE WIDTH PROCESSING CIRCUIT     ABSTRACT OF THE DISCLOSURE     A pulse signal processing circuit includes a NAND circuit that accepts periodic input pulses and an upper-limit detection signal from an upper limit detector and, when both an input pulse and the upper-limit detection signal are present, provides a setting signal to a flip-flop, When the flip-flop is set, it provides a discharging signal to activate a constant discharging current source.  A capacitor is discharged by the discharging current source until the potential across the capacitor reaches a lower reference potential, when a lower-limit detection signal from a lower limit detector resets the flip-flop to terminate the discharging signal.          The discharging signal also comprises the output pulse of the processing circuit.  Resetting the flip-flop initiates a charging signal to activate a constant charging current source to charge the capacitor until it reaches an upper reference potential, when the upper-limit detection signal is provided to the NAND circuit to condition it to receive the next input pulse.  Meanwhile, until the upper-limit detection signal is initiated, noise on the input line cannot provide an output pulse because that noise will not provide the setting signal from the NAND circuit to initiate the discharging signal.

Abstract: ABSTRACT OF THE DISCLOSURE:         The present invention relates to new, biologically active nonapeptides of the general formula (I) pGlu-His-Trp-Ser-Tyr-D-Tle-Leu- -Pro-NH-Et    (I) wherein X represents a hydrogen atom or a protective group, preferably a p-toluenesulfonyl (tosyl) radical.  These new substances are synthetic analogs of the luteinizing and follicle-stimulating hormones releasing factor and have high gonadotropic activity.  The substances are expected to find use in human and veterinary medicine, especially for the control of the estral cycle, for the treatment of estral disturbances or as a nonsteroidal contraceptive.  The nona-peptide compounds of the formula (I) can be prepared by processes which comprise reactions of combining the respec-tive amino acid or lower peptide radicals with the use of preparative methods of the peptide chemistry.  Preferable original methods for the elimination of the protective tosyl group in the position 8 and for the isolation and purifica-tion of the successive products are described.

Abstract: A SELF-ADJUSTING BRAKE DEVICE  Abstract of the Disclosure A self-adjusting brake device is disclosed for maintaining a predetermined clearance between a movable member of a disc brake and a tubular member frictionally positioned in a bore formed in a fixed member of the brake.  The brake device includes a screw which is fixed at one end to the movable member and which passes through the tubular member.  The screw has a head formed on its free end which is sized to contact an end of the tubular member.  As the movable member is displaced away from the tubular member a distance greater than a predetermined value, the screw head contacts the tubular member and incrementally forces its axial withdrawal from the bore.  This assures that a predetermined clearance is always maintained between the movable member and a rotating brake disc even as the brake liner on the movable member wears.

Abstract: ABSTRACT         A double-channel planar buried-heterostructure laser diode (DC-PBH LD) differs from the prior art structure by the provision of a third blocking layer which is disposed between the two conventional blocking layers. The third layer has a smaller carrier concentration than that of each of the other two layers.  The third blocking layer serves to reduce the junction capacity of the device which results in a greatly improved high frequency response.

Abstract: Abstract CRT Lensing electrodes having tapered apertures.           The invention pertains to an improved lensing means employed in compact plural beam in-line CRT electron gun assemblies resulting in small round spot sizes on the screen. This is effected by forming co-operating tapered apertures in a low potential lensing electrode and similar facing apertures in an adjacent high potential lensing electrode.          The larger openings of the two sets of facing tapered apertures provide lenses of larger than normal dimensions. Additionally, partial over-lapping of the apertures permits even larger lenses in the available electrode  areas, thereby effecting further improved lensing of the beams.

Abstract: ABSTRACT OF THE DISCLOSURE This disclosure relates to improved methods and apparatus for vertically stacking seismic-trace data col-lected by a digital field recorder during seismic pro-specting utilizing plural initiations of a low energy sur-face seismic source.  Seismic-trace data generated by consecutive seismic source initiations and acquired at a common detector location is weighted and summed together, and the sum is normalized prior to being recorded.          Accordingly, the signal-to-noise ratio of the seismic-trace data is improved.  The methods and apparatus by which the weighting values are calculated and applied pro-vides computational simplifications which reduce the pro-gram storage requirements and increase the computation speed of the microcomputer circuit preferably used to per-form the calculations and leads to savings in hardware power, size, and complexity.

Abstract: Abstract of the Disclosure An annulus pressure responsive downhole tool includes a housing having a power piston slidably disposed therein.          First and second pressure conducting passages communicate a well annulus with first and second sides of the power pis-ton.  A retarding device is disposed in the second pressure conducting passage for delaying communication of a suffi-cient portion of an increase in well annulus pressure to the second side of the power piston for a sufficient time to allow a pressure differential across the power piston to move the power piston from a first position to a second position relative to the housing.  The retarding device is an annular floating shoe having a large number of O-rings frictionally engaging inner and outer tubular members of said housing.  A pressure relief valve is communicated with the second pressure conducting passage between the power piston and the retarding device for relieving from the second pressure conducting passage a volume of fluid suffi-cient to permit the power piston to travel to its second position.  A spring biased pin disposed in the housing engages an indentation in an actuating mandrel attached to said power piston to releasably hold the power piston in its second position.

Abstract: Abstract of the Disclosure:       In an encoder operable in response to a discrete pattern signal divisible into a succession of segments to produce an output code sequence, a pitch parameter and a spectral parameter are extracted in a parameter calculator from each segment and from a spectral interval.          In an excitation pulse producing circuit, each spectral interval is divided into a plurality of subframes, namely, pitch periods with reference to the pitch parameter to divide each segment.  A minor group of excitation pulses is calculated from the segment at every subframe to form a major group of the excitation pulses in the spectral interval.  The excitation pulses of the major group are reduced in number with reference to adjacent ones of the minor groups in each spectral interval and are modified into a succession of modified excitation pulses.  The modified excitation pulses are combined with the spectral parameter into the output code sequence.          In a decoder, the modified excitation pulses and the spectral parameter are extracted from the output code sequence.  The pitch parameter is recovered by the use of the extracted and modified excitation pulses and is used to produce a reproduction of the discrete pattern signal  Alternatively, the pitch parameter may be sent from the encoder together with the spectral parameter and the modified excitation pulses as the output code sequence and extracted from the output code sequence in the decoder.
