Abstract: ABSTRACT OF THE DISCLOSURE        The disclosure relates to apparatus for center punching a hot metal billet preparatory to a piercing operation, in the production of seamless tubing.  The apparatus provides a simple, reliable, mechanical arrangement effective to automatically com-pensate for normal variations in the diameter of successive hot metal billets, such that the center punching operation is carried out with greater accuracy than has heretofore been attained in regular production operations.  The apparatus includes means for mechanically clamping a hot metal billet preparatory to center punching, and means for axially advancing a center punching tool into the end of hte clamped billet.  The center punching tool itself is mounted for linited transverse movement in relation to its advancing means, and is mechanically coupled to the clamp-0 ing means by a compensating mechanism.  Minor transverse adjust-ment of the position of the center punching tool in relation to the nominal axis of the apparatus, in order to obtain greater accuracy of alignment with the actual center line of a billet, is achieved by moving the center punching tool as a function of move-ment of the clamping mechanism.  The clamping mechanism serves inherently to sense the actual diameter of the billet which is being clamped.

Abstract: COLOR TELEVISION RECEIVING SYSTEM UTILIZING INFERRED HIGH FREQUENCY SIGNAL COMPONENTS TO REDUCE COLOR INFIDELITIES IN REGIONS OF s-2338     COLOR TRANSITIONS                         ABSTRACT OF THE DISCLOSURE             A color television receiving system for NTSC-type signals is provided with signal processing circuitry and methods for reducing the visibility of color infidelities, such as incorrect highs, polarity reversals, and errors in visual luminance,    which are visible in regions of sharp color transitions.   Such infidelities are substantially reduced by effectively supplementing either the chrominance or the primary color signals with inferred high-frequency chrominance components which components are, respectively, processed from signal information discovered to be inherently available in NTSC-type signals and their implicit constraints.  Specifically, it has been found that in regions of sharp color transitions, high frequency chrominance components can be scaled from the high frequency portion of the received monochrome signal in accordance with the respective ratios of the time rate of change of the received reduced bandwidth chrominance signal to the time rate of change of a comparable low frequency component of the received monochrome video signal.  Alternatively, inferred high frequency primary color components can be analogously derived.   A variety of specific circuit embodiments and methods can be used to process suitable inferred high frequency components.

Abstract: Abstract of the Disclosure A secure communication system for transmitting and receiving an encoded information signal.  The system generates at transmitting and receiving locations a predetermined unique pseudorandom code.  A synchronized tracking signal is imposed on the information to be transmitted and added to the informa-tion to form an intermediate signal.  The pseudorandom code is then multiplied by the intermediate signal directly so that the ultimate result appears to assume the character of pseudorandom noise, which is then transmitted to the receiving location. The synchronization and transmitted encoded portion is decoded at the receiver and used to generate a base signal for a pseudo-random generator at the receiving location, as well as initiate initial clocking pulse time for operation of the receiver pseudorandom generator.  The receiver then generates the pre-determined pseudorandom code and divides the same against the encoded signal being received to form an intermediate signal having no pseudorandom signal component, which is them filtered to removed the tracking and masking signal and thereby generat-ing the original information signal desired.
