Abstract: ABSTRACT OF THE DISCLOSURE           A beat frequency interference rejection circuit oper-ative in an electronic security system to inhibit the provision of an alarm indication for the duration of beat interference caused by an interfering transmitter.  A high pass filter is employed having a cut-off frequency which substantially blocks all frequency components produced by a resonant tag circuit while passing frequency components caused by the beat processing.          The high pass filter signal is processed to produce an inhibit signal to inhibit alarm production in the presence and for the duration of the beat interference.

Abstract: Title of the Invention SSB TRANSCEIVER            ABSTRACT OF THE DISCLOSURE    Two pilot signals transmitted at the beginning of transmission from a transmitting station are demodulated in the receiving station and one of the demodulated pilot signals is phase compared with a reference signal generated by the transceiver.  A phase comparator generates a control signal having a voltage corresponding to the difference between the compared signals. The control signal is input to a local oscillator of the transceiver which generates a signal to automatically tune the transceiver to the incoming signal frequency.

Abstract: Abstract of the Disclosure It is a feature of the invention to provide a label printing and applying apparatus having a brake member for applying a braking force to a composite web upstream of a printing zone, a feed roll which cooperates with a supporting material web of the composite web and a feed wheel for advancing the composite web, and an edge guide for guiding the composite web at its one side edge.  The brake member, the feed roll, and the edge guide are operable by a deactivating and activating mechanism.  This mechanism enables the brake member, the feed roll, and the edge guide, which are normally in their effective positions throughout the operating cycle of the apparatus, to be moved to their respective ineffective positions.  Thus, there is no interference with the threading of the composite web through the apparatus.  When the mechanism is operated, the brake member, the feed roll and the guide are simultaneously moved to their ineffective positions.  The mechanism includes an overcenter arrangement for releasably holding the brake member, the feed roll, the guide in either their effective or their ineffective positions until the mechanism is operated.

Abstract: DISPOSABLE CENTRIFUGAL BLOOD PROCESSING SYSTEM                      Herbert M. Cullis Abstract of the Disclosure A continuous flow centrifugal processing system for separating whole blood into fractional components in-cludes a centrifugal separator unit having a molded bowl shaped outer shell dimensioned to fit within a rotatably-driven casing on an associated centrifuge apparatus.  A bowl-shaped inner shell disposed within the outer shell forms therewith a thin separation channel radially spaced from the axis of ro-tation wherein fractions are separated from the whole blood under the influence of centrifugal force.  A rotating seal carried on the processing chamber between ports in the chamber and the non-rotating portions of the system.  The outer shell includes a relatively thin side wall portion which is inwardly biased toward a side wall portion on the inner shell when seated in the casing.  A plurality of projections on the side walls limit inward deformation of the outer shell to maintain a very close concentric spacing between the shell members to facilitate rapid separation of blood flowing through the chamber.          By reason of the shell members being molded, the processing chamber can be economically produced in large quantities for disposable one-time use.

Abstract: METHOD AND MEANS FOR REGULATING     SLIVER DRAFT UNIFORMITY     Abstract of the Disclosure The draft imparted to sliver during regular operation of a sliver drafting apparatus is correctively varied in propor-tion to uniformity variations then detected in the sliver.  Dur-ing at least part of each period of start-up of the apparatus, the sliver is subjected to a prescribed correction draft approxi-mately equal to an average of the draft corrections applied to the sliver over a relatively long time interval during the last-ensuing regular operation of the apparatus.  During that initial part of each start-up period required for the apparatus to accelerate to substantially full operating speed, the prescribed correction draft is either not applied or, alternatively, is scaled in proportion to the speed of the apparatus.  Preferably the correction draft applied to the sliver during transition from start-up to regular operation of the apparatus is approximately equal to the sum of the prescribed correction draft applied during the start-up period, and any additional correction draft resulting from uniformity variations then detected in the sliver.

Abstract: INVENTION:  DIRECT OXIMATION OF KETONES          INVENTOR:  JOHN N. ARMOR                             ABSTRACT         Ammonia, oxygen e.g., as air, and a ketone react in contact with a catalyst such as porous, amorphous silica or alumina which may or may not have a coating to form an oxime, at temperatures such as 50°-500°C.  The oximes have known utilities, including uses as oxidation inhibitors and as intermediates for production of amides.  In particular, when the ketone is cyclo-hexanone, the cyclohexanone oxime in the reaction product can further be converted to the cyclic amide, caprolactam, e.g. by contacting the product with an aluminosilicate catalyst having average pore diameter of at least 7 angstroms, especially a molecular sieve, suitably downstream in the same reaction vessel.          Caprolactam is the monomer starting material for nylon 6.
