Patent CA-1126446-A (CA)
Title: Polymeric light stabilisers for plastics
Inventor: RODY JEAN
IPC: C08G71/00
Filed: 1977-05-09
Granted: 1982-06-22
Abstract: Abstract of the Disclosure Condensation polymers or addition polymers which contain sterically hindered polyalkylpiperidine groups are proposed as light stabilizers for plastics. The polymers concerned are relatively low-molecular polymers and a difunctional derivative of a polyalkylpiperidine is additionally used for the manufacture of these. The piperidine radical can be present in the main chain or as a side group of the polymeric stabiliser. Polymeric stabilisers of this type do not tend to migrate out of the plastic or to be removed by extraction; they are therefore very permanent in use.

Abstract: ABSTRACT     A method of applying foamed insulation to pipe in contemplated by the present invention.  The pipe is moved longitudinally while being rotated about its longitudinal axis.          A sprayable, foamable liquid is directed onto the surface of the pipe from a stationary location and is allowed to partially rise before a protective outer jacket is wrapped around the rising foam.  The wrapping step includes application of sufficient pressure to the foam to increase the final density thereof, at the outer surface, by from 10% to 25% above the density if the foam was allowed to rise uninhibited.         The invention also contemplates a method of marking the line of juncture between two lengths of pipe which have been coupled together for coating purposes.  A marking liquid characterized by undergoing vaporization at a temperature below the maximum temperature reached during the exothermic reaction occurring between the foamable liquid and its blowing agent is applied to the pipe in conjunction with application of the foamable liquid.  The foamable liquid is allowed to rise and the area in contact with the marking liquid will rise to a greater degree than the remaining liquid as a result of vapor-ization of the marking liquid during formation of the foam.          This provides a ring of larger diameter foam in the location of the line of juncture.          The invention further includes a method and apparatus for handling pipe coated with foam insulation wherein an inflatable member having a casing formed from yieldable rubber-like material and presenting a rounded surface is used to support the coated but not fully cured foam insulated pipe.          The inflatable member is adapted to be inflated to a pressure sufficient to support at least a portion of the weight of the length of pipe without damaging the roam insulation or outer coating.  A series of the inflatable members may be positioned to receive the pipe as it comes off of the coating line with the first inflatable members which contact the pipe being inflates to a lower pressure than the subsequent inflatable members which contact the pipe.

Abstract: ABSTRACT      Apparatus is described for fibrillating a woven fabric comprising warp and weft tapes of polypropylene, such as is currently used as a primary carpet backing, by repeated needling of the fabric.  The apparatus includes a needle board on parts of which needles of generally rounded cross-section, preferably circular cross-section, are mounted to a density, preferably of the order of 120 needles per square centimetre with the tips of all the needles in substantially the same plane.  During the reciprocation of the needle board to fibrillate the warp and weft in the woven fabric, the fabric is maintained in a planar configuration by a support which accommodates the tips of those needles which penetrate the fabric without damage to the needles.

Abstract: ABSTRACT OF THE DISCLOSURE         A system and method is disclosed for fractionating at least one component from a gaseous mixture by pressure swing adsorption.  The system operates with at least one adsorption bed having a gas inlet and a gas outlet and a conduit for connecting the gas outlet with a product gas conduit at the end of the system.  A reservoir is inter-posed in the system such that its discharge can be selectively communicated with the product gas conduit at the end of the system, while the inlet of the reservoir can be selectively communicated with the gas outlet of the bed.  Accordingly, the gas from the reservoir can be discharged to the product gas conduit on interruption of the flow from the adsorption bed.  The advance in the art is in an improved uniformity of supply of the product gas due to the maintaining of a reserve of the product gas.
