Title: Process for producing Cationic Carbamoyl Polymers
Inventor: WISNER RALPH LESLIE
IPC: C08F8/00
Filed: 1966-10-18
Abstract: 1,153,207. Cationic carbamoyl polymers. DOW CHEMICAL CO. 18 Oct., 1966 [19 Oct., 1965], No. 46528/66. Heading C3P. Water-soluble cationic polymers are prepared by dispersing an aqueous solution of a watersoluble polymer composed of monoethylenically unsaturated monomer units, at least 20 mole per cent of which are units containing a carbamoyl group of the formula -CO-NH-R 1  (R 1  being H or C 1 -C 4  alkyl), in droplet form in a water-immiscible organic liquid, which is a non-solvent for the polymer, at 20-70‹ C. and then adding to the dispersion a watersoluble secondary amine and formaldehyde, or an adduct of these two compounds, so as to aminomethylate at least some of the amide groups of the polymer. The polymer product can be recovered by azeotropic distillation of the water present, and sedimentation or filtration to separate the polymer from the organic liquid; recovery can also be effected by extraction with a water-miscible solvent. The carbamoyl polymer may be derived from acrylamide, methacrylamide, N-methyl- or N-propyl-acrylamide, or an amide of maleic or fumaric acid; the amide component may be copolymerized with a monomer such as vinyl alcohol, alkali metal salts of acrylic or methacrylic acid, alkali metal styrene sulphonates, alkali metal maleates, N-vinyloxazolidinone, N-vinylpyrrolidone, 2-aminoethyl acrylate, trimethyl vinylbenzyl ammonium chloride, acrylonitrile, methacrylonitrile, ethyl acrylate, vinyl acetate, vinyl methyl ether and styrene. The amine reactant may be one having the formula R 2 -NH-R 3  where R 2  and R 3  are independently selected from C 1 -C 5  alkyl or hydroalkyl radicals (the total number of C atoms not exceeding 8) or R 2  and R 3  may together form a divalent hydrocarbon or oxahydrocarbon radical. The formaldehyde reactant may be used in the form of formalin, trioxymethylene or paraformaldehyde. Saturated aliphatic hydrocarbons and aromatic hydrocarbons are suitable as the water-immiscible organic liquid. Examples illustrate the aminomethylation of polyacrylamides which, in some cases, are stated to have a small proportion of the amide groups hydrolysed to carboxylate groups in the starting polymer.

Abstract: 1,119,770. Making copper wire. SOUTH WIRE CO. 19 Oct., 1966 [20 Oct., 1965], No. 46684/66. Heading B3A. A method of making a hot formed copper-base product having only uniformly dispersed copper-oxide inclusions comprises the steps of continuously solidifying molten copper-base metal in a closed wheel-type casting machine mould to obtain cast metal and initiating the hot-forming of the cast metal while it is in the condition in which it solidified, by maintaining the temperature of the cast metal at the solidifying temperature, which is within a range of temperatures for hot-forming the metal. Metal of a composition suitable for the production of tough pitch copper wire is continuously cast in a wheel and belt machine 13 and the solidified metal 14 is passed directly into a rolling mill 25. A furnace 15 may be provided to maintain the wire at its solidifying temperature. With this arrangement there is no set surface or surface concentration of copper oxide and photo-micrographs of transverse and longitudinal cross-sections are given, Figs. 2, 5, 8 and 11 (not shown) to illustrate the even dispersion of the copper oxide throughout the material, and the uniform fine-grained structure.

Abstract: 1,151,110. Regulating I. C. engines; gas turbine engine fuel systems. GOTAVERKEN A.B. Oct.28, 1966 [Nov.2, 1965], No.48356/66. Headings F1B and F1G. Delayed acceleration of prime movers as obtained through the limitation of maximum fuel delivery by a stop connected to a piston-in-cylinder device 4, Fig. 1 acted on by a pressure medium, and by an engine-driven metering member 7 which governs the outflow in a conduit 8 whereby the piston is brought back to an inactive position. Operation. On starting pressure air from manoeuvring member A and valve 18 pressurizes the oil in receptacle 10. Oil flows via a check valve 12 to the cylinder 5 to move piston 4 to its operative position. When starting is finished valve 18 is closed and receptacle 10 is relieved of pressure. For each revolution the metering member 7 allows the return of a fixed quantity of oil from the cylinder 5 back to receptacle 10 thereby altering the position of the stop engaged by arm 3 of the fuel control shaft 2, the setting of the latter being varied by a speed-responsive governor 1. In emergencies the two-way valve 14 is opened by pressure air admitted from a manuallyoperated valve 16 thereby relieving the cylinder 5 back to receptacle 10 to allow unrestricted engine acceleration. In one embodiment of the metering member a cylindrical body 19, Fig. 2 is rotated by enginedriven transmission 35, 28 and also moved axially by engagement of a cam 30 with a roller 32 or an adjustable stroke-limiting stop 33. Pressure oil is admitted from passage 22 to chamber 36 when slot 24 is registered with passage 22. When slot 24 is rotated into register with passage 23 the oil in chamber 36 passes to the outlet. In a modification of the transmission the axial elongation 38 is driven directly by the engine. In another embodiment of the metering member oil passes from the inlet (22, Fig. 4, not shown) along an axial passage (41) of a rotating cylindrical body (19) into an end chamber 42 containing a spring-loaded piston (43). When a radial passage in the body (19) is aligned with an outlet (40) the piston (43) forces out the metered quantity of oil in the end chamber 42.

The intention is to prevent the escape of generated dust into the ambient air whilst minimizing air turbulence within the booth. The rate of air withdrawal from the booth (e.g. through ducting 46) may be controlled by means of dampers or by regulating the fan speed, the control being effected either manually by the operator, or automatically using an air pressure differential or air flow meter at one or more of the booth openings. Accumulated dust is removed from within the booth periodically (e.g. by vacuum cleaners) such as when the reels 2, 3 and 4 of paper are being changed.

The polymer may be a homopolymer or copolymer of ethylene.  Processes are described and exemplified in which polyethylene is chlorinated in a single stage in the presence of oxygen, in two stages to the second of which oxygen is added, and in three stages of which the second is effected at a temperature above 130 DEG  C. and oxygen is added either to the third stage or to both the first and third stages.
