Abstract: FLUID SEALING ARRANGEMENT                 Abstract of the Disclosure A pair of housings include fluid passages for communicating pressurized fluid therethrough.  First and second bores in the housings each have one end open to fluid passages and have their other ends open at mating surfaces of the housings.  A hollow, cylindrical bushing is press-fitted into the first bore.  A hollow, cylindrical rubber packing is placed in the second bore. The bushing is axially longer than the second bore so that the outer end of the packing engages a corresponding end of the bushing.  As the housings are drawn together, the packing is axially compressed between the bushing and the annular bottom of the second bore.  Compression of the packing causes it to seal against the bushing and against the wall and bottom of the second bore so that fluid is confined to the interior of the bushing and packing as it flows between the passages.

Abstract: TITLE OF THE INVENTION:                               Umbrella ABSTRACT OF THE DISCLOSURE:         The inner ends of cover-supporting ribs of an umbrella are pivotally connected to a rib carrier which is longitudinally slidable in a hollow shaft by means of a projection extending out through a longitudinal slot in the shaft.  The rib carrier is slidable between a closed position in which the rib carrier is near the lower end of the shaft and the rib members together with the cover are in the shaft and an open position in which the rib carrier is at the upper end of the shaft and the rib members radiate out from the rib carrier so as to support the cover.         Each of the ribs comprises inner and outer tubular sections which are telescopically slidable one in the other.  When the umbrella is in open position, the telescopic ribs are extended so as to support a larger cover.  When the umbrella is in closed position the telescopic ribs are contracted so as to be received in a shorter shaft.  The ribs are biased to extended [position by an internal spring and latch means is provided for releasably holding the ribs in contracted condition.  A handle portion which is telescopically received in the lower end portion of the shaft releases the retaining latches of the ribs so that the ribs are extended when the handle portion is pulled out of the shaft to a single piece of two-way stretch material having inwardly opening pockets at its periphery to receive outer ends of the ribs.  The cover is stretched when the ribs are in extended open position and contracts with the ribs when the ribs are contracted.

Abstract: DIRECTED BEAM FUSION REACTION    WITH ION SPIN ALIGNMENT          ABSTRACT    In a fusion reaction where ions from two sources are forced by passage through magnetic fields to travel helically towards each other in opposite senses of rotation and directions at a common radius in an annular reaction zone defined by two coaxial spaced apart electrodes, a low velocity beam of gaseous ions from each source is established.  The spins of the ions are aligned while at said low velocity to produce polarized ion beams.  The ions in the polarized ion beams are accelerated to fusion velocities for injection into the reaction zone. Magnetic fields are applied to cause opposite directional travel of the ions in the polarized ion beams.  A D.C. radially directed electrostatic field is established between the coaxial electrodes for confining the beams to helical paths and compressing the ion beams.  The D.C. electrostatic field is applied as the confining field in the annular reaction zone.  Each of the two oppositely directed polarized ion beams are injected into the reaction zone wherein collisions occur.

Abstract: ABSTRACT OF THE DISCLOSURE             This invention relates to plastic tamper-evident closures which include a frangible portion which breaks upon removal of the top of the closure from a bottle, thus leaving a lower depending portion on the bottle as evidence that the closure has been opened. In such closures in which separate bridge members connect the upper portion to the lower portion there is the danger that the stresses developed during applica-tion of the closure to the bottle will break or fracture the bridge members. The present invention provides means for absorbing at least some of the forces incurred during applica-tion of a closure, which forces would otherwise have to be absorbed by the bridge members.

Abstract: ABSTRACT OF THE DISCLOSURE    In the manufacture of welded pipes, edge buckling or waving of the strip is prevented by heating.  In one method, during the process for bending the strip into a tubular form, the edges of the strip are heated so that tensile stress exerted thereon is reduced to a minimum and, thereafter, before the edges are abutted against each other, the strip is wholly heated so that the compres-sive stress exerted on the edges is reduced to a minimum. According to another mode, during the process for bending the strip gradually into a tubular form or during the process in which the edges of the strip are held in abutment against each other, the strip except its portions of the edges is substantially or partially heated so that the strip except its portions of the edges is subjected to compressive stress while the portions of the edges are subjected to tensile stress, and under these conditions the edges are welded together.
