Title: Treatment of fibres and the fibres thus treated
IPC: C08L71/02
Filed: 1970-07-02
Abstract: 1358836 Polyether polythiol textile-treating compositions CIBA-GEIGY (UK) Ltd 14 June 1971 [2 July 1970] 32240/70 Heading C3R [Also in Division D1] Compositions for application to cellulosic fibres comprise polyether polythiols obtained by end-capping polyol-alkylene oxide condensation products with mercapto-carboxylic acids or with epihalohydrin and sodium hydrosulphide, in admixture with aminoplasts free from ethylenic unsaturation. The aminoplast preferably contains at least two -CH 2 OR<SP>4</SP> groups linked to amidic or thioamidic nitrogen, where R<SP>4</SP> is hydrogen, C 1 -C 4  alkyl or acetyl, and may be based on urea, thiourea, or cyclic ureas of Formula I in which Y denotes either a group of Formula II or a C 2 -C 4  divalent group which may be substituted by methyl, methoxy and hydroxy groups, and may be interrupted by -CO-, -O-, or where R<SP>5</SP> denotes an alkyl or hydroxy alkyl group (1-4 C), Q denotes oxygen or sulphur. Further aminoplasts may be based on carbamates and dicarbamates of aliphatic monohydric and dihydric alcohols, and melamine. Curing may take place spontaneously or in the presence of catalysts and under conditions of elevated temperature, which accelerate the curing process. Curing catalysts for the polythiol include: siccatives, e.g. metal naphthenates, oxidizing agents; sulphur; sulphurcontaining compounds, e.g. mercaptobenzothiazoles, dithiocarbamates, thiuram sulphides, thioureas, alkyl xanthates, alkyl xanthogen disulphides and other disulphides; organic bases, e.g. mono- and polyamines; inorganic bases, e.g. sodium hydroxide, phosphate, tetraborate or carbonate; free radical catalysts, e.g. azodiisobutyronitrile, peroxides and hydroperoxides; and heavy metal salts and chelates. Curing catalysts for the aminoplast include latent acid compounds in the form of metal or ammonium salts, strong acids in solution or gaseous form, and organic or inorganic bases. Curing of the polythiol is assisted by high humidities and a pH in the range 7À5-12.

Abstract: 723,857. Lift trucks. RANSOMES, SIMS & JEFFERIES, Ltd., and RAYMENT, E. W. Dec. 15, 1953 [Dec. 22, 1952], No. 32473/52. Class 78 (3). In a lift truck provided with hydraulicallyactuated grab arms 20, 22 the cylinder 15 of the ram which effects raising and lowering of the arms acts as an accumulator for the grab arm actuating rams 18, 19 so that the arms continue to grip the load if a leak develops in the hydraulic circuit feeding rams 18, 19. The rams are fed from a reservoir 10 via a pump 9, a pressure relief and non-return valve 12 and a pair of manually-operated rotary valves 7, 31; whilst fluid is returned to the reservoir by pipes 16 and 37. A by-pass 41 connects the ram 15 with the inner ends of rams 18, 19 through a non-return valve 42 which, when ram 15 is under load and the pressure in rams 18, 19 is less than the pressure in ram 15, allows fluid to flow from pipe 14 to the rams 18, 19 sustaining the grip on the load; but which closes whenever the reverse condition arises and so prevents raising of the load by operation of the grab arm control valve 31. Figs. 2-6 (not shown), illustrate the construction and mounting of the valves which are arranged coaxially on a fixed part on the truck.

Title: Improvements in or relating to motor operated valves
IPC: F16K31/04
Filed: 1935-11-28
Abstract: 459,002. Motor actuated valves. PAYNE, M., 50, Hook Road, Surbiton, Surrey, and BRITISH THERMOSTAT CO., Ltd., Windmill Road, Sunbury, Middlesex. Nov. 28, 1935, No. 33032. [Class 135] A valve 1 is actuated in one direction by hydraulic pressure produced by a motor-driven pump and in the other direction by a spring or weight when the pressure is released. The pump 13 is mounted on a partition 6 between a liquid reservoir 7 and a pressure or working chamber 4, constituted in this instance by a bellows 8, and is driven by an electric motor 16. A fixed leakage path 14 in the partition 6, Fig. 1, is provided for the escape of liquid back to the reservoir 7 to relieve the pressure in the pressure chamber 4 when the motor 16 is stopped and so allow the spring 9 to close the valve. When the motor is running, however, the pressure is maintained against this leakage to keep the valve fully open. Instead of using a fixed leakage path the leakage may be controlled by a valve 17, Fig. 3, which may be thermostatically or pressure controlled to regulate the position of the valve 1 in accordance with a desired temperature or pressure condition, for example, the temperature of a cold storage chamber to which a cooling fluid is supplied under control of the valve 1. Under extreme conditions the valve 17 will open to its fullest extent and may also operate switch contacts to stop the motor, a subsequent return to normal conditions closing these contacts and restarting the motor. The actual working chamber for actuating the valve may be arranged remote from the motor and pump unit, being connected to the pressure chamber thereof by a suitable conduit.

Abstract: <PICT:0366585/IV/1> <PICT:0366585/IV/2> Means for applying liquids to travelling yarns, filaments, &c. comprises a pair of opposing surfaces of yielding absorbent material adapted to be supplied with liquid and means for pressing the surfaces together, the apparatus being adapted to permit passage of the yarn &c. between the surfaces and to preclude motion transverse to the yarn between the yarn and the surfaces. One form of apparatus comprises two pairs of arms, 8, 9, Fig. 1, each pair being pivoted together at their mid-points, corresponding arms being connected at their upper ends by blocks 10 and at their lower ends by platforms 11 provided with pegs 12 on which weights are placed in order to cause the blocks to be pressed together with a constant force.  The assembly is mounted over a container 5 for the liquid, and the absorbent material between which the yarn is pressed is constituted by wicks 15 folded over the blocks 10 and dipping into the liquid.  Guides 22 for the yarn are provided. In a modification, a spring 18, Fig. 4, is used to cause the blocks to be pressed together.  The apparatus may be applied to the treatment of artificial materials made from cellulose acetate or other derivatives of cellulose, continuously with their production or otherwise.  The treatment may comprise the application of lubricants, dyes, liquids intended to prepare the material for dyeing, or liquids intended to render the material sticky, so that, e.g. powders or fibres may be caused to adhere thereto.  Sizes or waxes may also be applied.  The liquid may be supplied to the absorbent material by drip tubes, or by wicks not forming the absorbent material themselves.  The apparatus may also be employed in the production of straws, tapes or bristles from artificial materials.  In this operation a bundle of filaments is passed through the device, which is used to apply a solvent or softening liquid which causes the filaments to adhere together; this adhesion may be followed by pressure between rollers to form a flat straw or tape.
