Abstract: ABSTRACT OF THE DISCLOSURE:         This disclosure relates to a sealant laminate to be primarily used in pneumatic tires to seal punctures made by external  objects, such as nails.  The laminate of the invention comprises a puncture sealing layer and at least one other layer, the puncture sealing layer containing a polymeric material that has been at least partially degraded by exposure to irradiation or to heat in the presence of a peroxide to yield its sealant properties; the degraded polymeric material is selected from the group consisting of polyisobutylene, copolymers containing polyisobutylene and polyethylene oxide.  The laminate may be in sheet or strip form with various cross-sectional shapes. The layers in the laminate comprise rubber compounds, some of which may contain agents which either assist or retard cure by irradiation so that the layers will have different physical characteristics during the manufacture of end products containing the laminate.  The laminate may be cured by any known method, either irradiation or thermal, after its assembly into the final product.

Abstract: Abstract of the Disclosure A large, 2 wire, 2-1/2D core memory includes four, 1K          (1024) by 1280, core frames with 1280 Y conductors each stringing and inductively coupling a column of 1024 cores in each of the four frames and 4K orthogonal X conductors each stringing and inductively coupling one row of 1280 cores.  A word position within the memory is defined by 5 pairs of Y conductors, a corresponding X conductor from each frame, and selection of relative current directions in the Y conductors.  Reading of a 20 bit word is accomplished with 5 sense amplifiers in four rapid succession read sub-operations.  Writing is accomplished in two sub-operations by separately controlling partial select digit currents in each of the 5 pairs of Y conductors.  A bidirectional X drive and switching arrangement utilizes overlapping X drive currents and shared circuitry to maximize memory speed and reduce electronic components costs.

Abstract: A B S T R A C T                 A machine tool high speed spindle assembly and draw bar assembly, wherein the spindle assembly includes a hollow, rotary spindle shaft, and the draw bar assembly is nonrotational relative to the spindle shaft. The draw bar assembly is axially movable within the hollow rotary spindle shaft, and it includes a tool holder gripping means. The draw bar assembly rotates with the hollow rotary spindle shaft during a machining operation. The draw bar assembly with its tool holder gripping means is moved by an actuator means between an operative position for retaining a tool holder or the like in the spindle shaft, and an inoperative position to permit a tool holder or the like to be removed from or inserted into the spindle shaft. A spindle shaft holding or gripping means retains the hollow rotary spindle shaft in a stationary position when the draw bar actuator means moves the draw bar assembly between said operative and inoperative, positions. The draw bar assembly actuator means and spindle shaft holding means each comprise collet means having relatively movable collet members and collet clamp ring members. The draw bar assembly actuator means and spindle shaft holding means are free from the spindle shaft and have no physical contact with said shaft during a machine tool operation.

Abstract: DISHWASHER ADDITIVE DISPENSING APPARATUS  ABSTRACT           A dishwashing apparatus having a dispenser operable at a pre-selected time in the dishwashing cycle for dispensing a treating addi-tive such as detergent.  The dispenser is arranged so that in response to a timer controlled cam a spring biased shaft to which the dispenser cover is mounted is released and the cover swings away from the dis-penser container opening.  The shaft is integral with a handle used to close the dispenser cover, and the handle and cover are interconnected by a camming device so that the cover is drawn into sealing engagement with the perimeter of the detergent container by the operator. The camming device further serves to break the seal by moving the cover in an axial direction away from the detergent cup in response to the timer controlled cam.  The detergent cup cover utilizes a highly effective rubber seal to compensate various tolerance conditions.

Abstract: Abstract of the Disclosure A flexible, modular communications processor is disclosed comprised of a plurality of microprocessors.  A demand assigned bus is provided to couple the microprocessors through an arbitra tor to an information storage and retrieval device.  Each of the microprocessors comprises a conventional integrated circuit microprocessor, associated local memory, transmitters and re-ceivers for coupling information to and from the bus and bus access circuitry, cooperating with the arbitrator to allocate the bus resource.  Communication input/output is handled by a plurality of microprocessors configured as line processors, each coupled to its associated interface switch, which, in turn, is coupled to modems or other input/output devices.  A background or executive microprocessor is included to manage system con-figuration and react to failures.  The common bus actually com-prises a pair of buses and modularity is provided by allowing the number of line processors to be changed by inserting or deleting circuit cards without affecting the operation of other line processors.  The communications processor may be redundantly configured by providing an additional arbitrator and additional executive or background processor and information storage and retrieval device such that all common equipment is redundant.  O the other hand, the processor can be configured for load sharing wherein a plurality of line processors and one of the executive or background processors operate on one bus under control of an arbitrator operating to and from one of the information stor?? and retrieval devices, while the other executive or background processor cooperates with a different group of line processors over the other bus under control of the other arbitrator to and from the other information storage and retrieval device.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention discloses a process for producing chloride dioxide which comprises (1) feeding hydrochloric acid and an excess on a stoichiometric basis of sodium chlorate produced in an electro-lytic cell for producing sodium chlorate into a reaction zone for producing chlorine dioxide;          (2) reacting the hydrochloric acid and the sodium chlorate in the reaction zone to form a gaseous reaction product containing chlorine dioxide and chlorine and so that sodium chloride produced is precipitated to form a slurry-like residual reaction mixture containing the precipitated sodium chloride;          (3) continuously removing the chlorine dioxide and the chlorine as the gaseous reaction product;          (4) simultaneously withdrawing the slurry-like residual reaction mixture containing the precipitated sodium chloride continuously from the reaction zone;          (5) feeding water to the withdrawn residual reaction mixture to dissolve the sodium chloride and form a solution containing sodium chloride;          (6) blowing air or an inert gas through the solution containing sodium chloride to remove any residual chlorine dioxde and chlorine from the solution;          (7) recycling the chlorine dioxide and chlorine removed from the solution to the reaction zone through an equalizing line; and (8) then recycling the solution to an electrolytic cell for the production of sodium chlorate.  This process is superior to the prior art processes in terms of equipment used and economy achieved and has also eliminated the risk of explosion caused by the reaction of hydrogen and chlorine in the electrolytic cell which is present in the prior art processes.

Abstract: FN 914,644 LOW FRICTION, ABRASION RESISTANT COATING          FOR TRANSPARENT FILM   Abstract of the Disclosure The use of abrasion resistant coatings on imaged transparent film which is carried by apparatus, such as motion picture film, causes frictional drag in the apparatus which in turn causes flickering of the images.          Conventional methods of reducing motion picture friction problems, coating with wax, do not work on the abrasion resistant coating.  The inclusion of particulate filler and/or oligomeric additives reduces the friction without mottling or reducing abrasion resistance significantly.
