Abstract: ABSTRACT OF THE DISCLOSURE An improved substantially leak-proof button cell, particularly adapted for use in hearing aids, comprising an outer cathode can and an inner anode can containing a zinc electrode material, preferably a zinc paste, the inner can being positioned within the outer can, with the outer wall of the inner can spaced from the inner wall of the outer can, a polymeric seal, preferably a polypropylene seal, positioned between the outer wall of the inner can and the inner wall of the outer can, the outer wall of the inner can having a coating of an alkali resistant elastomer or elastomeric adhesive, e.g. a self-curing butyl elastomer modified by a phenolic resin, which is pressure sensitive and having the property of deforming when subjected to pressure without cracking or forming voids, a catalyst electrode on a. flexible and permeable, preferably polytetrafluoroethylene, membrane and including a current collector, positioned between the polymeric seal and the inner wall of the outer can, and a separator between the zinc electrode material and the catalyst electrode.  The outer wall of the inner can preferably is provided with a locking means such as a flange, to lock the seal onto such wall, and the seal, also coated with the above elastomeric adhesive, is preferably tapered downward and forms a leak-proof seal with the inner wall of the outer can, a collector mesh or wire from the catalyst electrode being exposed in contact with the inner wall of the outer cathode can.        The button cell is fabricated by pressing the assembly of the inner anode can containing the zinc paste and the polymeric seal containing the coating of alkali or KOH resistant elastomeric adhesive, the separator and the flexible membrane with the catalyst electrode material thereon, by means of a plunger, down into the outer cathode can, until the flexible membrane of the catalyst electrode is disposed adjacent the bottom of the outer can.  During this operation, the tapered seal increases the pressure along the vertical part of the inner wall of the outer can, to aid in sealing the assembly within the outer can, and the elastomeric coating deforms under pressure without cracking, resulting in a leak-proof seal.  The tapered seal has a sharp upper edge which automatically trims the cathode, exposing the current collector to contact with the cathode can, and the upper edge of the outer cathode can is then crimped over the upper portion of the seal to provide the assembled button cell.

Abstract: BACKGROUND SUBTRACTION SYSTEM FOR PULSED NEUTRON LOGGING OF EARTH BOREHOLES            Abstract of the Disclosure.  Neutron generator in well logging instrument is pulsed 100 times having a time between pulses of 1400 microseconds.  This is followed by an off period of four cycles wherein 2800 microseconds is allowed for capture radiation to decay to an insignificant level and the remaining 2800 microseconds is used to measure background radiation.  This results in the neutron source being disabled four pulses after every hundred pulses of operation, or approximately a 4% loss of neutron output.  A first detector gate is open from 400 to 680 microseconds and a second detector gate is open from 700 to 980 microseconds.  During the 100 cycles, each of the gates is thus open for 280 microseconds times 100 for a total of 28,000 micro-seconds.  By scaling the gate count rate by a factor of 10, the background is subtracted directly.     -1a-

Abstract: METHOD AND APPARATUS FOR PRODUCING FIBER PULP IN A STEAM-PRESSURIZED GRINDING APPARATUS          ABSTRACT OF THE DISCLOSURE Method and apparatus for producing pulp from moisture-con-taining lignocellulosic material, such as wood chips, which is ground in a grinding space defined between a pair of grinding discs which rotate relative to one another in an environment of pressurized steam generated during the grinding process, in a clos-ed housing.  The grist discharged from the grinding housing is pro-pelled by the accompanying steam into a cyclone, where the grist is separated from the steam for further treatment, while the steam is recycled for further use in the pulping process.  The pressure in the cyclone is so controlled that a pressure is maintained therein which is substantially equal to a pressure drop which is sufficient merely to maintain the propellant force of the steam to convey the grist from the grinding housing to the cyclone while discharging the separated steam and recycling it for further use in the pulping process.

Abstract: ABSTRACT OF THE DISCLOSURE:         A method of condensing and/or polymerising sulfonated lignin containing materials to substantially water soluble products.          The method comprises adjusting the pH of the material such that a 3 % aqueous solution of the material has a pH below 7, adjusting the moisture content of the pH adjusted material to a value from 1 to 15%, and subjecting the resulting material to a heat treatment at a temperature range from 80 to 225°C in a manner to maintain the moisture content of the material at a value sufficient to allow the conversion to proceed, but less than 15%, and for a time period sufficient to form products having a viscosity at least 25% higher than the viscosity of the starting material, the vis-cosities being measured in a 50% aqueous solution at room tem-perature. Polymers based on sulfonated lignins are thus produced in a substantially dry state and at relatively low temperature and the end products obtained exhibit remarkably increased viscosities.

Abstract: ABSTRACT OF THE DISCLOSURE          A single barrel puffer circuit interrupter is taught.  The single barrel accomplishes the multiple pur-poses of electrical insulation between terminals, basic support and puffer gas containment.  The circuit interrupter has a movable nozzle-piston arrangement fixedly attached to a movable cylindrical hollow arcing contact.  The nozzle slidably engages a second cylindrical, hollow arcing contact and is disposed in slidable but sealed relationship there-with at all times, thus providing a shield between the arcing contact and the barrel of the circuit interrupter. In addition, one of the arcing contacts overlaps the other in telescoping relationship when the contact  are closed. This provides a lost motion feature for the puffer.  The lost motion feature allows the puffer gas to be compressed for a short period of time by the piston during a contact opening operation in a completely enclosed region before the gas is provided to the region of an electric arc between the opening contacts.
