Title: Rotary cylinder for stretching textile fibres
IPC: D02J1/22
Filed: 1972-02-23
Abstract: 1363361 Heating strands EMILE BLASCHKE & CO GmbH 23 Feb 1972 [25 Feb 1971] 8326/72 Heading D1F [Also in Divisions B5 and F2[ A roller for use in stretching textile fibres, has its cylindrical surface divided into a working zone 3, around which the fibres 6 pass, and an adjacent heating zone 4 which is heatable by, for example, a heater 7. The roller contains liquid 9 which is evaporated by the heat supplied to the heating zone. The resulting vapour condenses on the underside of the working zone and heats it to a uniform temperature. The liquid may be water or, more preferably, mercury. Temperatures of from 80‹ to 500‹C may be attained. Transfer of condensed liquid back to both the area where it is evaporated may be assisted by capillary ducts 16 or by a grid mesh on the interior of the cylindrical surface.

Title: Improvements in automatic slack adjusters for vehicle brake linkages
IPC: F16D65/60
Filed: 1965-02-26
Abstract: 1,025,398. Brake-adjusting devices. SVENSKA A.B. BROMSREGULATOR. Feb. 26, 1965 [Feb. 27, 1964], No. 8334/65. Heading F2E. An automatic slack adjuster for a vehicle brake linkage comprises means for automatic slack adjustment characterized by a clutch adapted to be disengaged when the braking force exceeds a predetermined amount to avoid excessive adjustment during heavy braking. A lever 3 actuates the brake by rotation in the direction of the arrow about the axis of a worm gear 4 which is splined to a brake-actuating shaft (not shown) and driven by the lever through a worm 6 which can be turned with a shaft 7 to adjust the slack. On operation of the brake a gear ring 46 turns with the lever until a key 50 attached to the ring reaches the end of a slot 51 in a stationary sleeve 47. The gear ring 46 is then stopped causing a rack 43 to move upwards against the action of a spring 45, turning a gear 41 which is free to rotate in one direction on the shaft 7. When the brake is released the spring 45 returns the rack 43 and the gear 41 which then turns the shaft 7 and the worm 6 through a one-way coupling 42 to reduce the slack. When the braking force exceeds a predetermined amount the force transmitted through the worm 6 causes the shaft 7 to move to the right against the action of a spring 35, disengaging a cone clutch 36, 37 and rendering the automatic slack adjuster inoperative. In another embodiment, Figs. 1, 2 (not shown), the shaft 7 is turned by a member 19 which is attached to a cover 17 forming part of the one-way coupling and which has an inclined slot 23 engaging with the brakeoperating rod 1 to turn the shaft. In another embodiment, Figs. 3, 4 (not shown), the shaft 7 is turned by an inclined slot in a sliding guiding member 28 which engages a pin 26 eccentrically attached to a cover 17 forming part of the oneway coupling.

Title: Improvements in automatic coupling devices for railway vehicles
IPC: B61G3/04
Filed: 1921-03-17
Abstract: 174,029. Soc. Usines E. Henricot. Jan. 11, 1921, [Convention date]. Couplings, automatic.-In an automatic coupling of the Janney type in which a knuckle-block is kept in the closed position by a key, the key is arranged to be raised either from above or below by means of one control member which can occupy two different positions of operation. The knuckle-block 4 is locked by means of a key 6, which is pivoted on a pin 9 in an elongated hole 11 in a rod 8. The rod 8 may either be operated from above the coupler head, as shown in full lines, by means of a rod or chain or may be reversed, as shown in dotted lines, and operated by means of a transverse lever 7. In uncoupling, the rod 8 is pulled or pushed upwards, the pin 9 rides along to the other end of the slot 11 and raises the key 6, which tilts and allows the horns 15 to rest on the ledge 14 of the coupler head, the knuckle-block being then free to open. When the key 6 is further raised a recess engages the end of a lever pivoted to the coupler head, the opposite end of which strikes the end 32 of the knuckle-block and revolves it to the open position. In the coupled position accidental displacement of the key is prevented by the end of the rod 8 being obstructed by a projection 12 on the coupler head.

Abstract: 307,850. Naamlooze Vennootschap Maatschappij voor Uitvindingen van Dikkers en Bargeboer. March 14, 1928, [Convention date]. Heating water.-The gas supply to a water heater is reduced or cut off after the water has been at boiling point for a time by the collection of condensate from the steam generated in a vessel into which dips a pipe conveying gas to the burner. In the example, Tig. 1, the gas supply to burners 4 at the lower end of a n-shaped flue 3, passes through a chamher 16 supplied with gas through a. tube 18 and connected to the burners by a tube 17 having a notch 19 at its lower open end. Steam generated in a vessel 11, which may be a compartment of the main water heater, passes by the syphon 13 to a collector 15 and thence to the chamber 16. A bye-pass passage 20 may lead gas to a pilot burner. The condensate-level tube 22 has a cock at its other end, to reset the apparatus, which may be inter-connected with the draw-off tap 10. In Fig. 3 the steam from a kettle 25 is condensed and collected in a chamber 16 carried by the hot-plate 26.

Abstract: 132,828. Vacuum Oil Co., (Vacuum Oil Co.). May 21, 1918. Straight tubes between headers.-A combined fractional condenser and preheater for use in distiliing oil consists of superposed sections each comprising a tubular condensing-unit 9, Fig. 1<a>, and a condensate-collecting pan 20, so arranged that the oil to be preheated flows downwards in a zigzag course through the units 9, and the vapours flow in a zigzag course in the opposite direction. In each condensing-unit, the oil entering by a pipe 5 passes from one compartment 7 of the header 8 through the upper bank of tubes 9 to the header 10, and back through the lower bank of tubes to the other compartment 12 of the header 8, finally flowing by a pipe 13 to the next condensing-unit. The vapour space of each unit is divided into compartments by a partition 23 between the upper and lower banks of tubes, and transverse partitions 36, 37 are provided in each compartment of the vapour space. The condensate flows along the partition 23 and the base plate 25, passing through apertures in the baffles 36, on to a baffle 26 which delivers it in the pan 20. The tubular condensing-units and the pans are arranged so as to be easily removed from opposite sides of the casing.

Patent GB-754385-A (GB)
Title: A process for producing porous products from unsaturated fatty oils and their derivatives
Filed: 1954-03-30
Abstract: A porous factice is prepared by mixing an unsaturated fatty oil or a derivative of such oil with water or an alcohol and with a substance which forms a gas with hydrochloric acid, and reacting the oil mixture with sulphur monochloride.  100 parts of dry linseed oil, 30 parts of sodium bicarbonate and 2 parts of ethanol are emulsified together, and 45 parts of sulphur monochloride are added with violent agitation.  Carbon dioxide is evolved to produce a porous mass, which stiffens into a resilient material. A pentaerythritol ester of an unsaturated fatty acid may be used instead of linseed oil.  A non-inflammable porous factice may be obtained by treating cod liver oil, water, sodium bicarbonate and ammonium phosphate with sulphur monochloride.  Fillers such as cellulose, wood meal, lignin, talcum, fuller's earth, or asbestos may be incorporated in the fatty oil before the treatment, and the oil may be polymerized or halogenated or a mineral oil may be added thereto.
