Abstract: 299,665. Bie, O. S. March 9, 1928. Exhaust silencers; pumps. - In an exhaust silencer for aircraft and like motors, comprising an exterior shell the front part of which is of approximate stream-line form and has exhaust outlets at its rear end, the shell towards the rear end is given a form which deviates in such a manner from stream line form that there is created, by the passage of the silencer through the air, zones with reduced air pressure and turbulence surrounding the outlet openings near the rear end of the shell. Referring to the upper half of the Figure which shows one form of silencer, the gases flow through tubes 1 into a collecting chamber 2 in a tangential direction. From chamber 2 they pass through a throat 3 to a distributing chamber 4 which tapers towards the rear end and has outlet openings distributed over the walls thereof. From these openings the gases flow forwardly through a chamber 5 and then rearwardly through a narrow channel 7, which is cooled by the surrounding air, to outlet openings 9. The rear end deviates from the stream-line form indicated by dotted lines and a zone of low pressure is created. In the modification illustrated in the lower half of the Figure the collecting chamber is provided with only one inlet 1 for the exhaust, and has a central air duct 10 for increasing the cooling action.

Title: Graft polymers and materials coated therewith
IPC: C08F257/02
Filed: 1959-03-05
Abstract: A process for preparing graft interpolymer latices from 45 to 65% by weight of methyl acrylate and 55 to 35% by weight of a monovinylidene aromatic hydrocarbon comprises adding an aqueous composition containing a polymerization catalyst at a substantially constant rate to an aqueous medium containing anionic or non-ionic emulsifying agent over a period of at least 140 minutes, during at least the first 50 minutes of such addition simultaneously adding a part of the hydrocarbon which part constitutes 50 to 30% of the total weight of monomers employed and during the remainder of said addition adding at a substantially constant rate the remaining 5 to 25% of the hydrocarbon and the whole of the methyl acrylate.  Specified monovinylidene aromatic hydrocarbons include styrene, nuclear alkyl, dialkyl- and trialkyl-styrenes, a -alkyl styrenes, vinyl naphthalene and vinyl toluenes, many examples being listed. Specified emulsifying agents are alkaryl polyether alcohols, sulphonates such as the sodium salts of sulphosuccinic acid esters, and ethylene-maleic anhydride interpolymers.  A portion of the catalyst may be retained and added after the addition of monomers is completed, the reaction mixture thereafter being allowed to reflux.  The latices may be made alkaline with ammonia, stabilized by the addition of the butyl half esters of styrenemaleic anhydride interpolymers, and used for coating paper, e.g. paper cups.

Title: New translucent panels having selective transmission and their manufacture
IPC: G02B5/20
Filed: 1961-03-02
Abstract: 915,217. Coated fabrics. RHONE-POULENC S.A. March 2, 1961 [March 12, 1960], No. 7738/61. Class 140. Panels having an infra-red action comprise a base coated with a layer of polyester resin and a metal layer of such nature and thickness that it is capable of selective transmission of radiation. The base of the panel may be a film of, for example, regenerated cellulose, cellulose acetate, cellulose acetobutyrate, nitrocellulose, vinyl chloride-acetate, stretched polystyrene or polyethylene terephthalate. This may be metallized by deposition of metal vapours under high vacuum, using aluminium, copper or a noble metal. The polyester resin may be formed in contact with the metallized face of the base film or with the other face. The metal layer may also be transferred on to the polyester resin by choosing a base to which the metal does not adhere firmly or by covering the film before metallisation with an anti-adhesive material, e.g. beeswax. After the polymerization of the polyester the film may be freed from the metal layer and the panels covered only with the metal coating are obtained. If polymerization is carried out on the unmetallized surface, the adhesion of the polyester may be improved by coating the base with say a varnish based on a vinyl copolymer or an acrylic resin. The polyester resin may be made from esters of unsaturated dibasic acids such as maleic and fumaric acid,-and if desired, esters of saturated dibasic acids such as phthalic acid with di- and polyalcohols. They may be copolymerized with monomers such as styrene, allyl phthalate or vinyl acetate, and reinforced by, e.g. glass fibres.

Filed: 1947-03-22
Abstract: 642,724. Bunch-building motions for textile ring spinning or like machines. ASHTON BROS. & CO., Ltd., and SMALLSHAW, F. E. March 22, 1947, No. 7891. [Class 120(ii)] A building mechanism for textile ring spinning or like machines of the kind in which the " chase " is effected by a cam and follower and the ring rail is simultaneously and progressively raised by pick mechanism has the cam movement for effecting the chase motion produced by two cam surfaces which give throws of different lengths, the surfaces being engaged by a single cam follower, so as to give a different chase during the formation of a bunch than during the main cop-building operation. A cam follower 14 is freely mounted for rotary and axial movement on a shaft 13 carried by a framework 10 pivoted on a shaft 11. A cam block having cam surfaces 19, 20 is fixed to a shaft 15 driven by a worm wheel 17 from a shaft 18. The cam surface 19 comprises a helical groove 21 cut in the surface of a block of generally square crosssection. The groove 21 leads into a groove 22 in the cam surface 20, which is formed by a block of heart-shaped cross-section. The minimum radius of the heart-shaped cam block is the same as the minimum width of the square block, but the maximum radius of the former is greater than the maximum width of the latter, so that the cam surface 19 may cause the framework 10 to oscillate and, through chains 25, 30, effect the rise and fall of the ring rail 41 necessary for forming a "bunch," but the greater throw of the framework 10 given by the cam surface 20 effects rotation of a ratchet wheel 44 on a shaft 45, by a ratchet 46, on each downward movement of the framework 10. The shaft 45 is connected to rotate the drum 24 and wind up the chain 25 so as to raise the ring rail 41. The pitch of the helical groove on the cam block may be varied or the cam block may be constructed without a groove and other means of moving the cam follower axially may be arranged. According to the Provisional Specification the cam surfaces may be formed on separate blocks.
