Abstract: ABSTRACT An improved high speed cast process for fusing fasteners, with strips of film at their base, to separately extruded film or sheet stock for making con-tainers with integral closure means. The process makes available multiple sets of male and female fastener elements, with variable spacing, in a single extrusion operation. The apparatus is configured so that adhesion between the fastener elements and the film or sheet occurs very closely to the die lips before significant cooling of the extrudate occurs. Containers with improved profiles are obtained because the base permits the profiles to remain relatively rigid during closing and opening. 27,173-F

Abstract: L'on décrit une fournaise qui brûle les déchets de bois, plus particulièrement le bran de scie et/ou les écorces. La fournaise est munie d'un brûleur à l'huile qui sert à partir le feu. Le courant d'air créé par l'éventail du brûleur à l'huile est dirigé dans une boîte perforée, située dans la chambre de combustion de la fournaise, et le bran de scie ou les écorces ou autres particules de bois tombent, selon un débit contrôlé, au-dessus de la boîte perforée. Le bran de scie est d'abord allumé par la flamme du brûleur à l'huile et ensuite la combustion se continue par le courant d'air provenant de la boîte perforée. Ce courant d'air a une composant verticale vers le haut pour allumer les particules de bois avant qu'elles ne tombent sur la boîte, et une composant horizontale vers l'intérieur de la fournaise pour éloigner les particules enflammées de la paroi latérale de la fournaise. Le système comporte un système d'alimentation du bran de scie et/ou écorce de bois à un débit contrôlé et une paire de trappes pour empêcher la fumée de s'échapper de la fournaise.

Abstract: METHOD OF CUTTING GLASS WITH A LASER AND      AN ARTICLE MADE THEREWITH                 Abstract of the Disclosure A method is disclosed for cutting glass with a laser.  The glass is superposed a suitable support and a laser beam is directed onto the glass.  The laser beam is focused to a point disposed at or about the surface of the glass.  The focused laser beam vaporizes a first thickness of glass, less than the entire thickness, and simultaneously heats the remaining thickness above the annealing temperature of the glass. A jet of gas incident upon the laser focal point removes the heated and vaporized glass proximate the focal point to create a hole through the glass.  By effecting movement between the glass and the laser and gas jet at a predetermined rate, the glass is cut. Also disclosed is an article including a unitary first sheet of glass having at least one complimental opening of predetermined configuration that does not extend to the edge of the glass and is cut by a laser.  One or more complimentary glass inserts coplanar with the first glass are disposed within the opening of the first glass, defining a groove therebetween.  A securing means is disposed in the groove to secure the compli-mentary pieces of glass in fixed edge to edge relationship.

Abstract: SHEAR TYPE PRESSURE RELIEF DEVICE FOR    HYDRAULIC ENERGY ABSORPTION UNIT            Abstract of the Disclosure An improved shear-type pressure relief device is provided which is useful in conjunction with pressure chambers requiring relief when system pressures exceed a predetermined level, such as in the shock absorbing piston and cylinder assemblies of present day vehicle bumpers.  The relief device is preferably in the form of an integral, metallic body including a flange in engagement with a pressure chamber wall adjacent a relief opening, with a projection extending into the opening.  The juncture between the flange and projection is advantageously very sharp (having a radius of less than about 0.020 inches) and the device is designed to shear upon experiencing high system pressures for relief purposes. The flange should be of sufficient thickness to provide stability across its unsupported dimension. However, if the shear and yield relationship of the material from which a relief device of preferred configuration is formed are such that yield could take place before shear, then it is desirable that the flange of the device be of a lesser sized cross sectional area adjacent to the sharp juncture between the flange and projection to assure shearing before significant yield occurs at a predetermined pressure level.  In the case of vehicle bumpers the shear device is located on the shiftable, bumper-mounted piston thereof, and circumscribes the usual station-ary, tapered, frame-mounted, flow-restricting rod. In this manner the normal operation of the bumper under moderate impact loads remains unaffected, whereas in the case of high impact loads the system pressures shear the device and provide a degree of shock absorption not found in conventional bumpers.

Abstract: ABSTRACT    A method for production of lined gaskets or gasket inserts is described, with which a pasty substance is arranged between the sealing surfaces (or correspondingly developed forms) and separated from these by two external layers, and hardened between the form-producing sealing surfaces.  The pasty substance preferably contains a filler of quartz powder whose void fraction is filled with a 2-component artificial resin.  The pasty substance can be applied with the assistance of a spray gun. preferred form of construction of such a gasket contains a hardened material layer and a corrugated ring adjoining it, which, along an inner peripheral area are surrounded by a band-shaped shell and are arranged between two gasket insert rings, which for their part are surrounded by a customary shell of polytetraf1uoroethylene or such-like. The production of gaskets of this type can take place at the point of use with the aid of simple means, so that costly operational interruptions can be shortened without expensive fitting operations or a re-ordering from a manufacturer being necessary.

Abstract: ABSTRACT OF THE DISCLOSURE      An useful dry battery driven liquid pump for pumping liquid such as kerosene or the like into a tank for an oil heater or the like very conveniently is disclosed which comprises a combination of a motor and a liquid pump disposed at the lower end part of a suction tube, a plurality of dry cells contained in a dry battery casing, a liquid surface level detector disposed at the lower end part of a delivery tube and a control circuit for controlling operation of the liquid pump properly in response to an output from the liquid surface level detector.  The liquid surface level detector includes a prism formed at the lower end of a cylindrical detector body, a light beam generating element and a light beam receiving element.  Control is effected in such a manner that the liquid pump is driven as long as the prism does not get wetted with liquid and thus light beam is reflected from the inner optical surface of the prism toward the light beam receiving element, while the liquid pump stops its operation when liquid is filled upto the level where the prism becomes wetted with liquid and thereby light beam passes through the optical surface of the prism without any reflection therefrom.  To prevent liquid from flowing further through the pump after its operation is stopped a communication groove is formed at the upper part of the suction tube through which the interior of the latter is communicated with the atmosphere.
