Abstract: A METHOD FOR PRESS-BONDING A REINFORCEMENT TAPE TO A SLIDE FASTENER WITH A SEPARABLE END STOP AND AN APPARATUS THEREFOR                 ABSTRACT OF THE DISCLOSURE A method and an apparatus are proposed for press-bonding a reinforcement tape of a plastic film on to a space section of a continuous length slide fastner chain to be finished into individual slide fasteners with a separable end stop so as to impart increased rigidity to the carrier tapes of the fastener chain at the end.  The method comprises positioning the space section of the fastener chain between an upper presser and a lower presser and, on the other hand, transferring a continuous length reinforcement tape by a predetermined distance in a direction perpendicular to the movement of the fastener chain, the reinforcement tape having been provided with a cut-out to fit the element rows of the fastener chain, so    that the cut-out is located just on the space section of the fastener chain between the pressers followed by closing of the pressers to effect press-bonding of the reinforcement tape to the space of the fastener chain either by heat melting or by high-frequency welding with simultaneous cutting of the reinforcement tape with a cutter blade.

Abstract: ABSTRACT OF THE DISCLOSURE           A plurality of capacitive touch pad sensors are multiplexed to the input of a common charge transfer analog-to-digital converter (CTAD) under the control of a control logic circuit. The no-touch digital output of each touch pad is stored in a memory.  The touch pads are then sequentially addressed and their output level is digitized in the CTAD and the digital output of each touch pad is compared to its no-touch value stored in the memory.  If the digital value read is sufficiently different from the no-touch memorized value, a touch-detection signal is given.  The no-touch digital reading in the memory is periodically updated, by a count of only one at most, if the updated no-touch value differs from the no-touch value in the memory.

Abstract: APPLICATION                           OF                 ERIK PERSSON                            AND                      JOHNNY SUNDIN                 FLUX CONTROL IN TAPE WINDINGS                 ABSTRACT OF THE DISCLOSURE         Disclosed are improved constructions for power transformers and reactors having windings of tape-formed conductor material which tend to reduce additional losses in the windings.  In the improved construction for a power transformer or reactor comprising a core containing magnetic material and having legs and a yoke and comprising windings including a tape-formed conductor material arranged concentrically around the core legs, the innermost of the windings has a first portion located nearest the core leg which has an axial length greater than the length of the portion of the winding located radially outside said first portion.  The first portion thereby forms a cylindrical shield for controlling the magnetic leakage flux appearing outside the ends of the winding.

Abstract: TITLE          CRYPTO MICROPROCESSOR FOR EXECUTING ENCIPHERED PROGRAMS          ABSTRACT OF THE DISCLOSURE         A microprocessor for executing computer programs which are stored in cipher to prevent software piracy.  Such a crypto-microprocessor deciphers the enciphered program piecemeal as it executes it, so that a large enciphered program can be securely executed without disclosing the deciphered program or associated data to persons who have access to the wiring of the computer in which the crypto-microprocessor is a component. Various methods of decipher-ing may be used including methods which result in the cipher of a byte being a complex function of the byte's address in memory.  Each crypto-microprocessor chip may use a unique cipher key or tables for deciphering the program, so that a program that can be executed in one chip cannot be run in any other microprocessor.

Abstract: Abstract of the Disclosure The disclosed case is of the type integrally molded from thermo-plastic resin.  At least one separator column is subdivided into partial pillars rising from the floor of the case for separating bottles in the case sufficiently to prevent  breakage in handling and transportation.  The respective column is subdivided by a gap so that bottles can be accep-ted together with a carrier or minicase, with one internal wall of one carrier or minicase or one external wall each of two carriers or mini-cases being slid into the gap of the column.  The improvements in the case include that the pillars have singlewebbed profiled walls, the one surface of said profiled wall facing the side walls of the box structure being part of said side faces of said column and the other surface of said profiled wall being part of said gap configuration; the upper mouth of the gap can be shaped as a slot so as to facilitate insertion of the carrier or minicase and to locate and adjust its walls; there are verti-cal reinforcement corrugations for stabilizing the pillars; a web of material of reduced length fills the gap between the facing edges of the pillars adjacent the floor; the pillars are anchored to a floor lattice by anchoring points which include at least points located on the outside of the pillars directly opposite inner reinforcement ribs.  These features stabilizing the spacing between the pillars, so that they do not pull toward each other as a result of stresses developing after removal from the mold.

Abstract: ABSTRACT OF THE DISCLOSURE     There is disclosed a method and composition for improving the fluidization characteristics and alleviating or inhibiting stickiness in a supported copper catalyst used as fluid bed catalyst in oxyhy-drochlorinations reactions.  The method involves the in situ preparation of the supported copper catalyst by addition of bare support on which no copper is deposited to the supported copper catalyst in the fluidized bed, or the use in the bed as the initial charge or as addition to the bed as makeup, of a composition which is a mixture of supported copper catalyst and bare support.  In either event, as the oxyhydrochlorination proceeds, a portion of the copper compound supported catalyst becomes released therefrom and deposited in situ on the bare support, and stickiness of the copper containing catalyst particles to one another in the fluid bed is alleviated or inhibited.

Abstract: ABSTRACT OF THE DISCLOSURE         Quantity production of friction nuts prepared for subsequent fusion of thermoplastic resin particles deposited in thread grooves therein, in which the nuts are supported with their axes vertical, a fluid slurry of the particles in a liquid carrier is introduced into the threaded interior of the nuts to fill the threaded opening, including the thread grooves therein, to a predetermined level from the bottom of the nuts. Excess slurry is then drained from the bottom ends of the openings.  In order to leave the threads clear of ob-struction at the bottom of the nut, the deposited slurry, after partially drying, is removed from the bottom thread convolutions by repeatedly inserting and withdrawing a sponge-like material directly into and out of the lower end of the thread opening, or by strongly agitating a small quantity of water in the lower part of the threaded opening.
