Abstract: PLASTIC CONTAINER WITH INTERNAL RIB RE-INFORCED BOTTOM AND METHOD OF FORMING SAME                  ABSTRACT OF THE DISCLOSURE          This disclosure relates to an unexpected increase in the strength of a bottle bottom of the champagne type by the addition of ribs internally of the preform when the pre-form is axially stretched prior to the blowing thereof within the blow mold.  Most particularly, by adding internal ribs to the interior surface of the bottom defining portion of the preform, the preform has the bottom forming portion unduly strengthened against shrinkage in wall thickness when the preform is axially lengthened through the use of a stretch rod.  The net result is that the stretching of the preform and the thinning of the wall is held to a minimum in the bottom forming portion of the preform and is trans-ferred primarily to the body forming portion of the preform where lesser wall thickness does not unduly detract from the strength of the bottle.

Abstract: "SOLID ELECTROLYTE OXYGEN SENSOR    AND METHOD OF MAKING SAME"                          ABSTRACT            Oxygen sensor with a disc type solid electrolyte has the disc sealed in a shrinkable ceramic tube by the pressure which is developed and the surface glazing which takes place as the tube is fired.  The tube is preferably formed of forsterite which can shrink about 25% during firing, thus causing the tube to become slightly bulged out in the region of the disc due to the interference fit produced by the shrinkage.  The porous electrodes on the top and bottom surfaces of the disc are prefer-ably omitted from a small region near one edge of the top and bottom sur-faces but are continued as a stripe or band down the edge from a diametri-cally opposite portion of each surface, the stripes and unelectroded areas associated with the respective surfaces being spaced to prevent electrical shorting.  The disc stripes are pressure bonded during firing of the tube to a pair of spaced lead stripes on the inside tube surface.

Abstract: ABSTRACT OF THE DISCLOSURE An improved rock-bolt grouting composition based on a cross-linkable unsaturated polymerizable polyester resin formulation in one component and a peroxide catalyst in a separate component, contains diffused water, preferably in the catalyst component, in an amount sufficient to provide a weight ratio of resin formulation to water no greater than about 6.0, and a particulate solid filter in both components in an amount sufficient to provide a weight ratio of filler to resin formulation of at least about 3Ø  The filled, water-extended composition generally expands during the cross-linking of the polymer, and greater interfacial strength in smooth-walled boreholes has been found.  Compositions in which water is the catalyst vehicle are preferred because their shelf life is better than those containing an oil-based catalyst.

Abstract: ABSTRACT OF THE INVENTION                     Flow Control Valve A valve device to control fluid flow through a passageway under a pressure head which may vary, has at least one vane (12) which lies in the passageway to restrict the fluid flow.  The vane (12, 18) is effectively flexible and resilient to deflect under fluid flow and so increase its restricting effect on increase in the pressure head and decrease its restricting effect on decrease in the pressure head so as to maintain a substantially constant flow output through the passageway (13).      The valve device may be incorporated in a nozzle (10) for insertion as one of a series along the length of an irrigation pipe (11), and the nozzle may be provided with a pointed head part (31, 46) and an outlet tube (26) or cap (27).

Abstract: D-23,02 TITLE: METHOD OF MAKING ELECTRICALLY-ACTIVATED PHOTOFLASH          LAMP WITH IMPROVED SEALED END PORTION                ABSTRACT A method of making an electrically-activated photoflash lamp which includes an ignition structure consisting of a pair of metallic lead wires and primer material disposed on terminations thereof. The structure is hermet-ically sealed within the end of the lamp's glass envelope by firstly applying heat (e. g. by gas-oxygen burners) to the open end portion of the tubing member (which eventually comprises the lamp's envelope) sufficiently to cause the heated glass to flow about the conductors. The final configuration of this end is achieved by introducing a gas within the tubing member's remaining open end to cause the heated end to expand to the desired shape, whereupon the end is permitted to cool. The hermetic seal, as achieved during the initial heating stage, is retained. The desired internal components (e. g., primer, combustible material, and combustion-supporting gas) are then added to the tubing member and the member's remaining open end sealed using a tipping off technique.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to an improved rechargeable metal-hydrogen electrochemical battery.  Each hydrogen electrode comprises a porous sheet of carbon particles catalyzed by plat-inum or palladium and bonded together with a hydrophobic binder, preferably Teflon, a registered U.S. trademark of E.I. du Pont de Nemours & Co. for polytetrafluoroethylene, so that the sheet is wetproofed.  A conductive metallic screen coated on one side with a hydrophobic binder is laminated on that coated side to the sheet.  The improved hydrogen electrode functions as an anode, with a cathode such as porous sintered nickel or silver plaque facing the screen-free side of the anode sheet and separated therefrom by a bibulous separator contacting both the anode and the cathode and containing sufficient liquid electrolyte to sub-stantially fill the pores of the cathode and anode.  Also included are sealing means, including peripheral gasket means, to prevent undesired leakage of electrolyte and gases.  The sealing means provides controlled access of hydrogen only to the screen covered side of the anode.  The conductive means joining the anode and cathode comprises the metallic screen with or without the metallic spacer present.  The cells in the stack are series connected.  No external connections are required for current flow through the stack.  Terminal end plates are provided to help seal the stack.          The improved battery exhibits improved performance, durability, reliability and compact construction.
