Abstract: ROLL TRANSFER MECHANISM FOR WEB MATERIAL DISPENSER          ABSTRACT      A dispenser for multiple rolls of web material such as paper toweling that is provided with dispensing mechanism to lead a web of material out of the dispenser to the user has supports for rotatably supporting rolls in primary and reserve positions, respectively, with transfer mechanism interactive with such roll supports and the dispens-ing mechanism to automatically transfer web feed from one roll to the other under predetermined sensed conditions. The transfer mechanism includes a pivotally mounted transfer frame swingable to be out of the way to facilitate dispenser loading with the dispenser cabinet cover open, the transfer frame being releasibly retained out of the way in conjunction with dispenser loading, and movable to a sensing location upon closure of the cabinet cover whereat depletion of web material supplied from the roll in the primary position is sensed whereafter the frame again shifts for tucking fingers on the transfer frame to press a web end portion of the reserve roll web material into the dispensing mechanism to therafter feed web material from such reserve roll. A keeper bracket loosely receives this web end portion incident dispenser loading with the action of cabinet cover closing causing the bracket to firmly grip such portion until the transfer mechanism coacts with the dispensing mechanism to thereafter feed web material supplied from the reserve roll.

The shank has a cold-pressed recess near the tapering end portion.  The tapering end portion is in the shape of a pyramid with its tip end disposed off the axis of the shank toward the recess so that the tapering end portion is bendable about the recess as its tip end is forced against the inner side of a cap of the button body during insertion of the shank into a hollow hub of the button body, during which time the stem portion opposes bending or other deformation.

Abstract: TITLE Preparation of Glycols from Ethylene Oxide INVENTORS Vijay S. Bhise Harold Gilman ABSTRACT A process for preparation of glycols in which the vapor remaining after the partial condensation of a conventional ethylene oxide stripper overhead vapor stream is contacted with an aqueous solution of ethylene carbonate to recover ethylene oxide.  No water need be removed from the enriched ethylene carbonate stream. Carbon dioxide is added and ethylene carbonate is formed by reaction at about 50 to 200°C and 5 to 150 kg/cm2 gauge in the presence of a suitable catalyst, preferably about 0.5-20 wt % of an organic phosphonium halide. After stripping off unreacted components, the ethylene carbonate is hydrolyzed to glycols in the presence of the same carbonation catalyst and at temperatures in the range of about 100 to 200°C and pressures of about 5 to 150 kg/cm2 gauge.  Optionally, ethylene oxide and ethylene carbonate may be co-produced.

Abstract: ABSTRACT           POLYMERIC ELECTRODE COATED WITH REACTION PRODUCT OF ORGANOSULFUR COMPOUND      Conjugated backbone polymer electrodes such as polyacetylene anodes are coated with the reaction product of the reduced polymer with a sultone or sulfonate.  Such coating may have occurred by using a sultone such as propane sultone in the electrolyte of a battery with such an anode, or in electrode prepara-tion.  The coating improves the stability of the elec-trode, especially when the polymer is highly reduced during battery use, whether the sultone remains as all or part of the electrolyte, or the sultone is replaced by a solvent such as propylene carbonate in the electro-lyte for the battery containing coated electrode.

Abstract: ABSTRACT       A venturi section or cone for a lightweight firearm such as a recoilless gun which is subjected to high transient pressures and temperatures on firing is formed from a resin impregnated multi-filament fibre material. The material in the form of an elongated tow is wound on a mandrel, cured, and then removed from the mandrel for subsequent operations such as machining or assembly.  During manufacture, a hot gas erosion preventing layer is first formed on the mandrel and a plurality of layers of tow are helically wound thereon at a helix angle selected to provide adequate axial and hoop strengths for resisting axial thrust and hoop loads produced on firing.  Lightweight recoilless guns using such venturi cones are lighter and cheaper to fabricate than conventional guns and will fire more rounds before excessive erosion causes them to be unusable.

Abstract: IMPROVED EPOXIDATION PROCESS  USING MOLYBDENUM CATALYSTS      (D#80, 313-F) ABSTRACT OF THE DISCLOSURE       A method of preparing an epoxide compound by re-acting an olefinically unsaturated compound with an organic hydroperoxide in the presence of a molybdenum catalyst is described.  Selectivity to the epoxide is at least 96%, con-version of the hydroperoxide is at least 96%, yield to the epoxide is at least 94% and recovery of the catalyst is at least 90%.  These excellent results are accomplished by using a molybdenum catalyst, such as a molybdenum complex of 2-ethyl-1-hexanol,  at a concentration of 100 to 1000 ppm based on total charge, preferably 200 to 600 ppm.  The mole ratio of olefinically unsaturated compound to organic hydro-peroxide is preferably in the range of 0.9:1 to 3.0:1 and the reaction temperature is preferably in the range of 50 to 180°C.   It was further surprisingly discovered that the method of this invention works much better with t-butyl hydroperoxide as the organic hydroperoxide than with other hydroperoxides, such as cumene hydroperoxide.
