Abstract: ABSTRACT           A sub-munition warhead contains several flechettes arranged in a circumferential pattern.  A canister with a length less than that of the flechettes surrounds the rear ends of the flechettes.  A frangible fairing joins the canister to a small diameter nose cone.  An indexer adjacent the nose cone and a sabot for each flechette retain the flechettes in position on a piston joining the canister and the nose cone.  The warhead is normally launched with a rocket motor.  It is spun so that on burnout, the warhead is travelling at high speed and spinning.  On burnout, a fuze is ignited and the piston is propelled down the canister.          This drives the flechettes forwardly, rupturing the fairing and allowing the flechettes to separate for independent flight to a target.

Abstract: DISTILLATION  PROCESS  WITH  HIGH  THERMO-DYNAMIC  EFFI-CIENCIES     ABSTRACT OF THE DISCLOSURE         A process for distillation of two materials of differing boiling points particularly propane, ethane or carbon dioxide from natural gas is described in which the conventional distillation tower is divided into a first tower (102) at higher pressure than a conventional tower and a second tower (104) at lower pressure.  Liquid drawn from the first  is expanded to the lower pressure through two or more stages (111,112) with cool extracted (65,62) at each stage and used to cool (65,62) gas (51) withdrawn from the top of the first tower to keep the top tray at a required temperature.  Gas (19) withdrawn from the second tower (104) is compressed and cooled for return to the first tower as a reflux.   The use of the cool from the expanded liquid and the use of the two towers provides an improved thermo-dynamic efficiency and avoids the use of costly turbo-expanders.

Abstract: Abstract of the Disclosure A hollow, tubular light conduit including a wall of a transparent polymeric material, and the wall having a structured surface and an opposite, smooth, glossy surface, and at least a portion of the cross-section of the wall lying in a smooth arcuate curve, wherein light striking the inner surface, within an acceptable angular range, is contained by total internal reflection.  The structured surface includes a linear array of substantially right angled isosceles prisms arranged side-by-side to form grooves.  In addition, the perpendicular sides of the prisms make an angle of approximately 45° with the tangent to the smooth surface. Because of the flexibility of the light conduit and its ability to totally internally reflect light, a manipulated light conduit may be utilized in a variety of ways, for example, as a light fixture whereby some of the light directed into the light conduit is emitted from the light conduit for illumination or for use as a secondary light source.  A suitable light source may include artificial or solar energy.  However, when the light fixture operates as a warning light it is preferred that a strobe light be used.

Abstract: This invention provides organopolysiloxane materials having cone penetration between about 100 and about 350 (10- <sup>1</sup>mm) and ultimate elongation of at least 100% and having reduced surface tack. This invention provides three methods of obtaining said materials with reduced surface tack. The first method comprises applying to the surface of such material an organic peroxide or a photoinitiator and irradiating the surface with ultraviolet light to further crosslink the surface to reduce or eliminate the tack of the surface. The second method comprises mixing a photoinitiator, such as benzophenone, in an organopolysiloxane fluid, thermally crosslinking the organopolysiloxane fluid to produce the material with the above cone penetration and ultimate elongation then irradiating the surface of the material with ultraviolet light to reduce or eliminate the tack of the surface. The third method comprises mixing a photoinitiator, such as benzophenone, in an organopolysiloxane fluid, crosslinking the fluid by irradiating a layer of the fluid with ultraviolet light to produce the above cone penetration and ultimate elongation properties then further irradiating the crosslinked material to reduce or eliminate the surface tack; this method can be carried out by simultaneous irradiation with ultraviolet light from two sides of a layer of the organopolysiloxane wherein one surface is irradiated at a higher intensity than the other surface. The materials produced by this invention are useful as tapes and sealants.
