Title: Manufacture of polyvinyl resins in powder form
Inventor: PETERS HEINRICH
IPC: C08J3/12
Filed: 1957-07-01
Abstract: Polymers of vinyl esters of fatty acids are obtained in powder form by spray-drying an aqueous dispersion of the polymer containing a plasticizer and a dissolved cellulose ether or salt of a water-soluble cellulose ether acid.  The powders are non-sticky and can easily be reconverted to aqueous dispersions. The cellulose ether compound may be introduced during polymerization of the vinyl ester. Specified cellulose compounds are methyl cellulose, hydroxyethyl cellulose and sodium cellulose glycollate.  The preferred proportions of these compounds is 0,1 to 5% of the weight of resin and plasticizer.  Polyvinyl acetate and propionate are specified resins with dibutyl phthalate as plasticizer.  In one of the examples, the polymerization is described of vinyl acetate in aqueous dispersion containing methyl cellulose, sodium persulphate and sodium phenyl phenolate, the dispersion then being plasticized and spray-dried at 90 DEG C. Spray-drying may also be effected at lower temperatures under reduced pressures, and in an atmosphere of protective gas.

Filed: 1975-05-16
Abstract: 1515862 Cross-linked polyimide coatings GENERAL ELECTRIC CO 16 May 1975 [3 June 1974] 20864/75 Heading C3R A polymeric coating is formed on a substrate by applying thereto a thin film coating of a heat-curable diamide-diacid-diamine monomeric material which is formed as the reaction product of 2 moles aromatic diamine with 1 mole aromatic dianhydride in a solvent system at below imidization temperature and then curing the coating to form a highly cross-linked polymer. It is postulated that (for the reaction product of 4,4<1>-diaminophenyl methane and benzophenone tetracarboxylic dianhydride) the cross-linking may result from a reaction giving a product of the structure of from one giving a product of the structure and that the actual product is one resulting from a combination of both reactions taking place together. The diamide-diacid diamine monomer may be converted to its nitrogen base salt allowing the coating to be formed from an aqueous medium.

Title: Improvements for driving and stopping mechanism
IPC: D05B69/16
Filed: 1920-07-17
Abstract: 149,305. Reece Shoe Machinery Co., (Assignees of Schoenky, A. R.). July 28, 1919, [Convention date]. Sewing - machines; driving; starting and stopping gear.- High and low speed driving- gears are arranged in the foot of the pedestal of a tootstitcher. The low-speed gear includes a worm-gear and a oneway ball ratchet clutch and the high-speed gear includes a friction clutch controlled by a pedal. Both gears drive on to a cross. pulley shaft from which the operating-shaft of the stitcher is driven by usual belt-gear and positive stopping clutch. A band brake surrounds the dr.ven member of the high-speed clutch, and is applied by the pedal gear when the high-speed clutch is opened. With the pedal 27 in the position a, Fig. 2, the machine is stopped. When the pedal is depressed to the position b, the pedal rod 28, through the tooth engagement 71 of sliding members 68, 72, draws the pedal rod 29 downwards and the clutch on the stitcher shaft is closed. Further movement of the treadle to the position c, removes the brake from the driven member of the high-speed clutch and closes that clutch. This further movement is not transmitted to the pedal rod 29 since a cam slot 76 causes the sliding member 72 to move laterally out of engagement with the tooth 71. Movement of the treadle from c to b disconnects the high speed gear but does not move the pedal rod 29. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a positive stopping clutch on the stitcher shaft. This includes a cone clutch 81, 117, Fig. 7 (Cancelled), a positive stop cam 80 and a follower 100 which is pivoted upon a spring-pressed plunger 93. During running, the follower 100 is in the dotted-line position. When the pedal rod 29 is free to rise, toggles 107, 108 and a lever 109 are used to urge the follower into the full-line position and it moves into that position when the low part of the cam comes up to it. Thereafter in the continued rotation of the cam, the follower and the plunger 93 are depressed and, by connexions 90, 87 and 86, the clutch members 81, 117 are separated. A band brake 116 surrounding the member 117 is at the same time tightened by means of toggle levers pivoted to a part 112 of the plunger 93 and the machine is brought to rest with the follower 100 on the highest part of the cam. Dog clutch teeth 118 prevent slipping in the clutch when the clutch is closed. The toggle arm 107 is integral with a lever arm 119 which has a connexion with the thread tension release gear. This subject-matter does not appear in the Specification as accepted.
