Abstract: A process for the production of a sterile composition containing lecithin and polyvinyl pyrrolidone is disclosed in which the lecithin and polyvinyl pyrrolidone, optionally with one or more preservative powders are admixed in a solvent comprising about 75% to 90% methyl isobutyl ketone and about 10% to 25% isopropyl alcohol, and the solution passed through a millipore filter in order to render the ingredients sterile. The process is usefully employed in the production of injectable compositions of amoxycillin and ampicillin.

Abstract: A connection system for interconnecting a heat exchanger and a pipe union, in which the pipe union (5) opens out into a connection tube (4) of a heat exchanger water box (3), with the pipe union being fixed to a flexible pipe (6) via a permanent connection and being fixed to the connection tube via an easily-released resilient connection. The resilient connection is constituted by a locking device comprising two diametrically opposite fingers (19) carried by a ring (18) fixed inside the water box (3) and disposed coaxially with the connection tube (4). The fingers (19) slope towards the axis of the connection tube and they are resilient in the radial direction, with two notches (22) being provided in the leading end (7) of the pipe union (5) in order to receive the locking resilient fingers (19) by snap-fastening when the pipe union (5) is engaged in the connection tube (4). The invention is applicable to providing rapid connections in the automobile industry.
Abstract: A one piece elongated shoulder pad comprised of a rubbery material for use with a shoulder strap, which comprises a base having a top, a bottom, and opposed first and second longitudinally extending sides, said first side being narrower than said second side, and at least one pair of opposed flexible cooperating tab means for retaining said shoulder strap on said pad, said tab means being integrally attached to and extending away from said base, said tab means each including cooperating fastening means for detachably fastening said tab means together, whereby said shoulder strap is retained under said tab means and on said top when said tab means are detachably fastened together.
Abstract: The process for producing a plastic-like cured woody molding, which comprises applying a pressure necessary for plasticizing at least a woody component at temperature of from 120.degree. C. to 180.degree. C. to a composition comprising (A) an oligoesterified woody material obtained by alternately adding a polybasic acid anhydride and a monoepoxy compound having unsaturated double bond to the hydroxy groups of a woody material and (B) an oligomer obtained from a polybasic acid anhydride and a monoepoxy compound having unsaturated double bond with the addition of (C) a radical polymerization initiator to simultaneously perform the plasticization and crosslinking by the polymerization of the unsaturated double bonds. The plastic-like cured woody moldings thus obtained have dense and glossy surfaces and are particularly excellent in dimensional stability, mechanical properties and heat distortion temperature.

Abstract: A connection system for interconnecting a heat exchanger and a pipe union, in which the pipe union (1) opening out into an opening (6) of the water box (2) of the heat exchanger is fixed firstly to a flexible pipe in permanent manner and secondly to the water box (2) by an easily released resilient connection. First axially projecting guide means (3) fixed to the pipe union (1) slide over second guide means (4) fixed to the inside surface of the water box (2), with said first and second means being configured to co-operate with each other. The invention is applicabhle to providing rapid action connections in the automobile industry.
Abstract: A connection system for interconnecting a heat exchanger and a pipe union, in which the pipe union (7) that opens out into a connection tube (4) of the heat exchanger water box (3) is permanently fixed to a flexible pipe (31) and is releasably connected to the tube (4). The leading end of the pipe union (7) has a neck (6) which is divided into a plurality of axial fingers (11) which are resilient in a radial direction and which carry snap-fastening catches (8). The catches (8) are circumferentially spaced apart and they alternate with cylindrical portions of the pipe union. The inside surface of the tube (4) has two sets of axially extending grooves (12, 13). The first set of grooves (12) are catch-receiving grooves for engaging the catches (8) when the union (7) is thrust axially into the tube (4).

Abstract: A compound, or a solvate or salt thereof, of formula I: ##STR1## in which: R.CO-- is an acyl group containing a substituted or unsubstituted carbocyclic aromatic or heterocyclic aromatic group;R.sub.1 and R.sub.2 are independently hydrogen, C.sub.1-6 alkyl, C.sub.1-6 alkenyl, C.sub.1-6 cycloalkyl or C.sub.1-12 cycloalkylalkyl or together form a C.sub.2-6 polymethylene or C.sub.2-6 alkenylene group, optionally substituted with a hetero-atom, provided that R.sub.1 and R.sub.2 are not simultaneously hydrogen;Rx is C.sub.1-6 alkyl or phenyl, or Rx together with R.sub.1 form a --(CH.sub.2).sub.3 -- or --(CH.sub.2).sub.4 -- group, is useful for the treatment of pain.
Abstract: This open support has the configuration of a "C" shaped sleeve (1) provided along the free ends of the "C" with two opposed lateral shapes (3) connected by weakened zones (2); each shape being provided with an inwards directed upper thin triangular projection (4) and a lower convex projection (5) so that during the assembly of the support (1) on the cable (6) the sleeve (1) is subjected to elastic strain and the shapes (3) begin to oscillate around the weakened zones (2) so that, due to an elastic thrust of the shapes (3) acting on the external lower semicircumference of the cable (6), the latter is pushed inwards and will snap into the sleeve (1) causing a further oscillation of the shapes (3) until they reach their end position while pushing the cable (6) inwards by boundary pressure.
