Abstract: TITLE OF THE INVENTION:            APPARATUS FOR APPLYING A LOAD TO A STRAIN GAGE TRANSDUCER BEAM            ABSTRACT OF THE DISCLOSURE       In a platform scale in which the strain gage transducer beams are preferably formed as an integral part of a platform it is important that any distortions such as horizontal or angular force components that could fal-sify the reading of the weight, are prevented from af-fecting the transducers.  For this purpose, the verti-cal load or weight representing force components are transmitted to each strain gage transducer beam through at least two cooperating curved, preferably spherical, surfaces.  One curved surface has a larger curvature than the other so that a sufficient motion in any horizontal direction is permitted.  The horizontal yielding pre-vents the transmission of a horizontal or angular force component to the sensing strain gages of the respective transducer beam but does not adversely affect the ver-tical force transmission to the transducer beams.   1400/ar                          - 1 -

Abstract: ABSTRACT           A bottle closure cap stampable from sheet metal as a shallow cylindrical inverted dish having a rounded juncture, foming a fillet, between its crown and its cylindrical wall; a layer of elastomeric material being disposed in the fillet and engageable with the axial end of the bottle when the cap is attached.  A generally radially extending rip tab is integral with the cylindrical wall at the bottom edge thereof and is adapted to tear through the cylindrical wall by a generally circumferential pull of the user to gain access to the container.  A rip line is provided commencing at a corner defined by the bottom edge of the cylindrical wall where it meets the rip tab.  The rip line extends at a shallow angle across the cylindrical wall to a level which is spaced below the crown, continuing parallel to the crown circumferentially about half-way around the closure cap. The installed closure cap can relieve excessive interior pressure and reseal itself, the closure cap pressure in the container being relievable gradually while the rip tab is being pulled to gain access to the container. Installation of the closure cap requires much less axial pressure than conventionally required.

Abstract: ABSTRACT          TITLE: RIGID BUILDING FRAME WITH INFLATABLE MEMBER            The invention describes a method of constructing a building involving the assembly of a rigid skeletal framework of struts defining the contours of the desired building which is for example domed, or part-barrel shaped.  A membrane or envelope of plastics material is inflated within the framework to lift the struts from a state of compression under their own weight into a state of tension.  The membrane is then coated on at least one side with settable material such as concrete or other glass fibre reinforced material and the membrane deflated when the material has set.   In an example of the invention, support zones at the junctions of the struts support the set material.

Abstract: ABSTRACT OF THE DISCLOSURE         The method comprises applying a braze material to a sleeve in a manner so that the sleeve may be attached to a tube so as to bridge the defective region of the tube.  The sleeve is constructed to have a groove on the outside surface thereof that extends  around the  entire circumference.  The groove is filled with braze material and a flux is applied to the braze material in a manner to prevent the braze material and flux from becoming removed.          Once such a sleeve has been inserted into the defective tube, the sleeve is internally expanded in the area of the sleeve wherein the groove is  located.  The expansion of the  sleeve  in the  area wherein the  groove  is  located causes the braze material to closely contact the  inside surface of the tube.  The other end of the sleeve can then be either similarly placed in contact with the tube or welded to the tube.  Next,  the area of the tube wherein the braze material is located is internally heated so as to create a brazed joint between the sleeve and the tube.          When the joint has cooled,  a leaktight joint is formed between the sleeve and the tube.

Abstract: Apparatus for introducing sweep gas through a baffle system adapted for use with glow discharge deposition apparatus in which successive amorphous semiconductor layers are deposited on a substrate. The deposition apparatus includes at least a pair of adjacent dedicated deposition chambers into each of which different process gases are intro-duced, the chambers being operatively connected by a gas gate.  Inert gases introduced into a first one of the adjacent chambers are unidirectionally swept through the gas gate to minimize back diffu-sion of process gases from the other of the cham-bers.  The baffle system is adapted to prevent said sweep gases from entering into turbulent flow when traveling through the gas gate passageway. Further, a sufficient volume per unit time of sweep gas is introduced to insure that some sweep gas flows into the cathode region of the first chamber, thereby substantially preventing process gases and plasma from escaping from the cathode region and forming silane powder.

Abstract: DIFFERENTIAL PRESSURE ACTUATED VENT ASSEMBLY                   ABSTRACT OF THE DISCLOSURE      A differential  pressure  actuated  vent  assembly is connected into an oil well tool string.  In one form of the invention,  the tool  string  includes  a  packer  device, a perforating gun attached to the lower end of the tubing string, with the vent assembly being interposed between the gun and the packer device.  Fluid pressure within the tubing string is effected on one face of a piston associated with the vent assembly, which reciprocates the piston and commu-nicates the interior of the tubing string with the annulus around the tubing string while carrying out the step of perforating the formation.  Movement of the piston and the subsequent detonation of the gun preferably are both accom-plished sequentially in response to the dropping of a bar down through the tool string.  The bar opens a passageway leading to the piston, and immediately thereafter, before the pressure differential between the interior of the tubing string and the annulus is equalized, the gun is detonated, thereby obviating damage to the formation.
