Title: Improvements in the production of vinyl chloride polymers
IPC: C11D1/10

Abstract: Vinyl chloride polymers containing free carboxyl groups are prepared by copolymerizing vinyl chloride and a monoethylenically unsaturated carboxylic acid, or an anhydride or acid chloride of such an acid, or a partial ester of a monoethylenically unsaturated polycarboxylic acid, alone or together with other copolymerizable monomers in the presence of a dispersing agent and a polymerization catalyst and in an aqueous medium containing from 5 to 25% by weight of a water-miscible organic solvent or mixture of solvents based on the weight of water. Suitable monoethylenically unsaturated carboxylic acids include maleic, fumaric, acrylic, methacrylic, crotonic, itaconic and aconitic acids and the proportion of said acid, acid anhydride, acid chloride or partial ester is preferably between 0,3% and 10% of the total weight of polymerizable compounds employed. Suitable water-miscible organic solvents are low molecular weight alcohols, glycols, esters of low molecular weight, e.g. methyl acetate, and ketones, e.g. acetone methyl ethyl ketone. Mixtures of two or more of these solvents may be used and other organic solvents which are normally substantially immiscible with water may also be added in small quantities to the water-miscible solvent or solvents. Dispersion agents mentioned are gelatine, polyvinyl alcohol, starch, methyl cellulose, glycol cellulose and other high molecular weight water-soluble polymers such as polyalkylene oxides. Polymerization catalysts which may be used include organic peroxides and hydroperoxides, e.g. acetyl peroxide, tertiary butyl peroxide, lauroyl peroxide and succinyl peroxide, hyponitrous esters, e.g. benzyl hyponitrile and azo compounds having molecules containing the group >C-N=N-C< in which the two carbon atoms are non-aromatic in character, e.g. a , a 1-bis-(a , g -dimethyl valeronitrile) and azo di-isobutyronitrile. The catalyst may be added to the monomeric materials as a solution in an organic solvent. Chain-transfer agents, e.g. chloroform and tetrachloroethylene, may be added. Small proportions of other polymerizable compounds may be included, e.g. vinyl esters of saturated monocarboxylic acids, acrylonitrile and methacrylonitrile the proportion employed should not exceed 40% of the total weight of polymerizable compounds employed. The products of the invention may be used as heat-sealable coatings on aluminium foil, lacquers for beer cans and for coating glass and wood surfaces.

Patent ES-373663-A1 (ES)
Title: Fuel feed devices for internal combustion engines
IPC: F02D41/34
Filed: 1969-11-11
Abstract: A fuel feed device for internal combustion engines has a main throttle operated by the driver and an auxiliary throttle which opens automatically and progressively as the air flow rate in the induction pipe increases. A pressurized liquid fuel injection means is located in the pipe downstream of the main throttle and controlled by an electromagnetic valve. A flat, opaque disc containing one or more ports is mounted on a shaft rotated by the engine. The ports pass a light beam between a light source and a photocell mounted on a displaceable common support coupled to the auxiliary throttle. When illuminated the cell energizes the electromagnetic valve. Each port has a spring-urged lever mounted adjacent to it so as to mask or expose part of the port, according to the centrifugal force due to the speed of the disc and hence of the engine. The shape of the port and displacement of the support are arranged so that more light passes, hence more current flows and the fuel flow is reduced or eliminated on deceleration of the engine. The levers are of sheet-metal pivoted between their center of gravity and their masking nose.

Patent ES-405203-A1 (ES)
Title: Method and apparatus for producing a flat fan paint spray pattern
IPC: B05B7/04
Filed: 1972-07-27
Abstract: A method and apparatus for spraying a coating material such as paint, in a flat fan pattern. In the gun a stream of paint under a relatively low pressure is caused to flow in an annular film. Streams of gas at a slightly higher pressure are directed against the paint film so that the gas is sheared into microbubbles which are entrained in the paint stream to form a froth. The froth flows through a chamber in which the bubbles disperse uniformly in the paint and is then discharged through a narrow slit nozzle effective to give it a fan shape. As the froth is released to atmospheric pressure, the microbubbles of air expand rapidly and rupture, causing the paint to disintegrate into finely atomized drops. The apparatus includes a cooperating orifice plate and collar which define a thin annular paint flow channel and a plurality of air injection channels which intersect the paint flow channel. Air is introduced through these channels and is directed against the paint film. In the preferred gun, the nozzle includes a hemispherical endwise portion provided with an elongated discharge slot. A protuberance or ball is disposed within the nozzle and deflects the froth so that the froth passes through a relatively narrow passageway between the ball and nozzle. A modified gun includes a conventional airless flat fan orifice and does not utilize an internal ball.

Abstract: An electrical circuit for digitally displaying an input electrical signal to minimize fluctuations in the output and maximize the speed of response to changes in the input signal whereby the input signal is applied to a first low pass filter and a second low pass filter having both a lower threshold frequency and a slower response time to changes in the input signal than the first filter.
