Abstract: A METHOD AND APPARATUS FOR WELDING GIRTH JOINTS IN PIPE           LINES ABSTRACT OF THE DISCLOSURE       A method for welding girth joints in pipelines using two welding heads comprises the steps of moving each of the welding heads upwards around the pipeline along the respective section of the girth joint, feeding a welding wire to each of the welding heads so that the welding wire is fed substantially tangentially with respect to the surface of the pipe, and for-ming a circumferential weld by moulding it to hold the molten metal of the welding bath in the welding zone.      An apparatus for carrying out the method for welding girth joints in pipelines comprises an annular track struc-ture having at least two carriages mounted thereon which are connected with drives adapted to impart a translatory motion to the carriages. Each of the carriages carries a welding head provided with a welding wire feeder and a weld moulding member arranged opposite to the joint being welded. The welding wire feeder includes a guiding nozzle extending under the weld moulding member, with its axis being oriented tangentially to the surface of the pipe to feed the welding wire into the welding zone through the groove of the joint.      The moulding of the weld prevents the molten metal of the welding bath from flowing out of the groove of the joint, which makes it possible to considerably reduce the number of passes required and thus to increase the quality and efficiency of the welding.

Abstract: ABSTRACT OF THE DISCLOSURE          A high voltage capacitive drive circuit for coupling a dc or pulsed dc input voltage from a control input to a relay having a high volt-age output circuit is described in which the output of the high voltage re-lay circuit is electrically isolated from the control input thereto without the use of optical couplers.  The combined capacitive drive circuit and high voltage switch circuit of the present invention may be integrated on a single silicon chip using conventional isolation fabrication techniques to provide good isolation between the control input and the output of the high voltage relay circuit.  A pair of matched capacitive couplers are driven in a push-pull mode to pump electrical charge to a floating control circuit which turns on the high voltage relay contact.  An exclusive OR circuit pre-vents high voltage signals on the contact terminals from inadvertently turning the contact ON or OFF by being responsive only to out of phase in-puts.  The described high voltage switch and capacitively coupled drive cir-cuit is suitable for fabrication on a single semiconductor chip.

Abstract: ABSTRACT    A generating circuit for producing atrial and ventricular timing signals for a pacemaker which allows independent control of ventricular rate and atrial-ventricular delay.  A voltage ramp signal is generated and compared to a reference voltage signal by a voltage comparator which produces an output signal when the ramp voltage reaches the reference voltage.  A second voltage comparator compares the reference voltage with a second ramp voltage signal which is generated by offsetting the first voltage ramp signal so that the second ramp signal parallels and leads the first voltage ramp signal by an offset voltage difference.  The second voltage comparator produces a second output signal when the second ramp signal equals the reference voltage.     Alternatively, the second output signal can be produced by offsetting the reference voltage signal and comparing it to the voltage ramp signal in the second comparator.  The first and second output signals provide atrial and ventricular timing signals.  The ventricular rate is controlled by adjusting the relationship of the reference voltage and the first voltage ramp signal.     The atrial-ventricular delay is independently controlled by adjusting the amount of the offset voltage.

Abstract: PHN. 9548               22 ABSTRACT:         A method by which code words in a received digi-tal bit stream can be detected in a reliable manner, without word synchronization, in an environment where the bit error rate is high. The bit stream is divided into data blocks having a number of bits equal to the number of bits of the code word. The number of times that the same bit state is detected in a plurality of blocks in the same relative position in the data block is accumulated. For each bit position the accumulated value is compared with a threshold value and when the threshold value for each bit position is exceeded, the code word is detected from the digital state of the accumulated value. The cyclic permutation of the bits of the code word and the code word itself represent one an the same message. In a device using this method, bit counter feeds a word counter with the bit stream applied at an output, a shift register receiving each data block as effectively formed by the word counter. Counters count the "1" and "0" occurrences in each shift register section in successive data blocks. Threshold devices pro-vide outputs when their thresholds as given by generators are exceeded. The outputs are gated by combinational o logic gates to record a detected code word in a register which addresses a store to find the associated message.

Abstract: Abstract A semiconductor integrated circuit using charged coupled device (CCD) technology for performing demodulation of time-varying signals which have been phase or amplitude modulated.  The CCD circuit performs a sampling of the time-varying signal at a suitable sampling frequency depending upon the frequency of the phase or amplitude modulation of the carrier.  The CCD device converts the sample into an equivalent charge packet which is used to control the control electrode of a field effect transistor in an amplifier circuit.  The magnitude of the sample is representative of the amplitude of the carrier so that the output of the field effect transistor represents a demodulated signal.  The circuit is a braod spectrum device, operable with a signal frequency from the audio into the gigaHertz (GHz) frequency range.
