Abstract: ABSTRACT          The repair of a reinforced elastomer article having a hollow therein relates to utilizing an amine curable polymer or prepolymer and a cured elastomer patch.  The hollow in the elastomer as well as the areas juxtaposition to the patch is coated with a treating agent.  The amine curable polymer or pre-polymer which may have rubber particles therein is then applied to the hollow as well as to the area between the patch and the elastomer and cured at am-bient temperature.  Alternatively, gum rubber is directly applied to the hollow and also to the treated patch area.  One area of use is in the repair of tires.

Abstract: TITLE OF THE INVENTION                    DRAWBAR SWAGING APPARATUS WITH SEGMENTED CONFINEMENT STRUCTURE     ABSTRACT OF THE DISCLOSURE           A swaging apparatus includes a drawbar to be inserted in a tubular structure that is to be expanded radially.  Two confinement structures define the axial boundaries of an annular pressure zone within which one or more elastically deformable pressurization rings are confined.          One or both of these structures includes a plurality of arcuate segments elastically held together and presenting a cam surface.  A cam ring interacts with that cam surface to radially expand a cylinder formed by the segments in response to swaging pressure, thereby preventing inelastic deformation of the pressurization rings.

Abstract: ABSTRACT OF THE DISCLOSURE            A  mounting arrangement for a windscreen glass is shown.          Around  the top and sides of the windscreen  opening,  a rubber  section is mounted on a bodywork flanged  joint, the  rubber having embedded in it a metal carrier  which has an extension which emerges outside the  plastics  to provide  an  exposed  stiff metal  lip  which  partially embraces  a recess holding mastic.   The section of  the mounting arrangement along the bottom of the  windscreen opening  differs in that its metal carrier does not have such  extension  or  the  exposed  metal  lip,  and  the plastics immediately beneath the recess has a slot  into which a stiffening member can be clipped. The windscreen is mounted in position by sliding it  upwardly in to the sides and  top  of  the windscreen opening. The glass is thus trapped  in  position  behind the exposed metal lip and sealed and adhesively secured by  the mastic.  It is then  fixed  in  position in the section along the lower part  of  the  windscreen opening by bending the base of the recess in that section downwards,  pushing the glass into  the  mastic  and allowing  the  rubber  to  resile upwards  with  a flap thereof making  contact  with  the outside  of  the glass.  The stiffening member  is  then replaced into position in the slot mentioned above.

Abstract: Abstract The invention provides a method for making fur bearing strands from hides of fur bearing animals and a yarn from such strands suitable for producing a fur garment.  The yarn has low stretch characteristics by virtue of treatment of the hide portions used to make it.  Strands are made from hide portions joined side by side at abutting longitudinal edges and slit transversely of the joined portion.  A yarn is made from the strands, which may be joined end to end, by longitudinally twisting them so that the fur is substantially about the exterior thereof.

Abstract: ABSTRACT       The  present  invention  relates  to  an  arrange-ment for the omnidirectional orientation of an antenna. The arrangement comprises a housing mounted on a fixed mast so that it can rotate around the axis of the latter, and an antenna support mounted on the housing so that it can rotate around an axis perpendicular to the mast. Two  adjustments  assemblies  comprising  a  toothed  ring integral with one of the elements of the said articula-tions and a worm engaged on the said toothed ring and mounted  immovable  in  translation on the other element of each articulation, allow the antenna to be adjusted finely in elevation and in the azimuth.  The arrangement also  comprises  locking means  for  locking  each of the articulations.    In the  event  of  the deterioration of the adjustment arrangements associated with the fixing means,  the  effectiveness  of the immobilization is not prejudiced.

Abstract: PROCESS FOR REDUCING THE HYDROXYL CONTENT OF OPTICAL WAVEGUIDES                     ABSTRACT OF THE DISCLOSURE           The inert or oxidizing auxiliary gases used in the manufacture of optical waveguides often contain traces of water which can be the cause of disruptive OH groups in the glass fiber.  According to the invention, this disruption is overcome by reducing the hydroxyl content of optical waveguides by treating the auxiliary gases with heavy water (D20), so as to replace the hydrogen atom in the OH groups with deuterium, and then subjecting the gases to a drying step.  Preferably, the auxiliary gases are subjected to a preliminary drying prior to treatment with D20.

Abstract: ABSTRACT     A gas-permeable element of a refractory material for flowing gases into a metal treatment vessel through its lining comprises a refractory body having longitudinal sides, a free inner end surface at which a refractory material of  the  refractory body is exposed,  and an opposite outer end surface. At least one local opening provided with a metal insert  extends  through  the refractory body  to form a gas passage between the inner and outer end surfaces, the metal insert being formed as at least   one laterally closed thin metal channel arranged in the local opening of the refractory body.  A gas-distributing chamber is separated from the re-fractory material of the refractory body by a metal sheet plate.  The channel  is tightly mounted in   the metal sheet plate so that the refractory material of the refractory body is maintained  free  from loading with a gas pressure,  the metal channel having an outer side. A coating coats the outer side of  the metal channel so as to be located between the metal  channel  and  the  refractory body,  the coating being composed of a refractory material having elastic properties so that it absorbs expansions which take place in the gas permeable  element  and  therefore mechanically protects  the metal channel.

Abstract: A B S T R A C T            An implantable blood pump.      Inside a flexible shell (10), a deformable pocket (20) is connected to blood circulation via an inlet valve (30) and an outlet valve (40).  The pocket is compressed by a floating assembly comprising a drum (50), and a bracket (60) rotatable about the axis thereof.  One of the edges (21) of the pocket (20) is fixed to the drum (50); the opposite edge (22) is connected to the bracket (60) by a traction link (70), for example an inextensible sheet.          Relative rotation between the drum and the bracket over a fraction of a turn enables the pocket (20)  to be wrapped around the drum (50) and the assembly returns to its starting position under the effect of venous pressure.          The disposition of the various components provides a self-adapting lever which limits mechanical losses to rolling friction between the drum and the pocket.

Abstract: Abstract A propellant configuration for a solid propellant rocket motor A propellant configuration has a generally cylindrical housing (14) containing a generally cylindrical main grain (12) having a central cavity (16) and a plurality of interior flutes (24) formed in the main grain (12) about said central cavity (16). At the time an air launched vehicle is being fired, it is desirable for the rocket motor to quickly accelerate the missile from the launch rack as well as to minimize the effects of the rocket exhaust on the launching means. This is accomplished by an igniter assembly (20) supported in the central cavity (16) having means there-in for bringing about combustion. At the time of actua-tion of the igniter assembly (20), hot gases are direc-ted along flutes (24) formed in the interior of the main grain (12), to cause burning thereof to take place, with the burn surface area of an igniter grain (64) being in a pre-established relationship to the burn surface area of the fluted main propellant grain (64), such that the igniter grain (64) will be totally consumed at the time that the flutes (24) of the main propellant grain (12) are consumed. In this way the total burn area of the main grain (12) is reduced to a value which produces a distinct and highly desirable reduction in the total mass flow rate, this preferably occuring adjacent the end of the launch mechanism.
