Abstract: ABSTRACT In a stereophonic reproduction system,especially for a cinema, a centre channel signal is derived by combining left and right channel signals.  In order to harden the centre image, particularly in speech, the left and right channel signals are compared and, when they include significant amount of correlated information, the relative gain of the centre channel is enhanced by boosting the gain of that channel and/or cutting the gain of the left and right channels.  The test for correlation of information is preferably restricted to speech frequencies and the enhancement of relative gain may be performed only at middle frequencies.

Abstract: D-502(MCO) ABSTRACT OF THE DISCLOSURE       A multipole circuit breaker is constructed with a single rod pivotally mounting all of the movable contact arms to a common one piece molded insulating carrier.  Individual torsion springs engage each of the contact arms to provide contact pressure when the circuit breaker is closed.  The construction of the contact arms and carrier are such that under severe overcurrent conditions electrodynamic blowoff forces  acting on the contact arms may bring about contact separation that is substantially as great as the contact separation that takes place when the circuit breaker is opened normally by its contact operating mechanism.

Abstract: ABSTRACT           An instrument for determining the complex mechani-cal response of samples incorporates two parallel sample arms each pivotally mounted at their central portion by flexure pivots of precisely known spring constants.  The sample is mounted on one end of each.  An electromechanical driver acts on the other end of one arm to maintain the arms and sample in mechanical oscillation on about the pivots. A displacement transducer senses the mechanical motion.  A feedback amplifier between the displacement transducer and the driver maintains the oscillation at a constant amplitude and at a resonant frequency determined primarily by the sample.  With this arrangement the driver and displacement sensor are removed from the sample and its usual thermal chamber.  This improves the stability of the instrument.  At the same time the arms are dynamically balanced about the pivots and hence are re-latively insensitive to vibrational upset.

Abstract: Abstract of the Disclosure A sheet metal can end or cover comprises a largely or wholly removable panel bounded by a peripheral tear line, and an integral closure within the panel, the closure being defined by a generally arcuate groove or depression formed at one side therof with a coterminous, rupturable weakening line having a mid-locality extending nearer to but spaced from the panel tear line to provide a lifting lip therefor and a defiectable tongue portion extending toward the center of the panel.  The weakening line and the tear line are preferably of the fractured but intergral type fully disclosed in our U.S. Patent 3,681,630 and extend on opposite sides of the panel.  On depressing the locality of the mentioned weakening line with a tool, such as the tip of a spoon, the closure opens then permitting the tip to bear upwardly on the inside of the lifting lip as the bowl of the spoon is pivoted upon the tongue portion.  Consequently the panel tear line is progressively ruptured and the panel may be readily tilted upwardsly or fully removed by bearing downwardlyon the tool handle.

Abstract: MESSAGE VERIFICATION AND TRANSMISSION    ERROR DETECTION BY BLOCK CHAINING   ABSTRACT OF THE DISCLOSURE       A message transmission system for the secure transmis-sion of multi-block data messages from a sending station to a receiving station.     The sending station contains cryptographic apparatus operative in successive cycles of operation during each of which an input block of clear data bits is ciphered under control of an input set of cipher key bits to generate an output block of ciphered data bits for transmission to the receiving station.  Included in the cryptographic apparatus of the sending station is means providing one of the inputs for each succeeding ciphering cycle of operation as a func-tion of each preceding ciphering cycle of operation.  As a result, each succeeding output block of ciphered data bits is effectively chained to all preceding cycles of operation of the cryptographic apparatus of the sending station and is a function of the corresponding input block of clear data -bits, all preceding input blocks of clear data bits and the initial input set of cipher key bits.

Abstract: SELECTIVE INTERMODULATION DISTORTION             MEASUREMENT     Abstract of the Disclosure An improved noise loading arrangement and method are disclosed capable of measuring low intensity inter-modulation distortion products, such as introduced in the operation of individual wideband transmission repeaters.          The improved arrangement and method also have the further capability of resolving individual orders of distortion products.  The arrangement utilizes a noise signal generator that produces a pseudorandom signal made of several spectral components providing high spectral density throughout a large bandwidth to simulate a broad-band message load obtained by frequency multiplexing several independent signal sources.  The noise signal is shifted in frequency before a quiet band is produced in the signal applied to the transmission apparatus to be tested.  The orders of intermodulation distortion products appearing in the quiet band of the output signal of the transmission apparatus are individually measured to evaluate same.  Automation of the test sequence is provided by a computer which acts as a general controller.          The computer also processes the test data obtained by using a conventional signal averaging technique.                             - i -
