Patent GB-880408-A (GB)
Title: Pressure relief valve
IPC: E21D15/51
Filed: 1957-11-05
Abstract: 880,408. Hydraulic pit-props. BECORIT GRUBENAUSBAU G.m.b.H. Nov. 5, 1957 [Nov. 7, 1956; May 15, 1957], No. 34488/57. Class 20(2) [Also in Group XXIX] A spring loaded pressure relief valve includes a storage chamber having a restricted inlet for the pressure fluid to be controlled and an outlet controlled by the valve element. In the first example, Fig. 1, the ball valve 8 is loaded by an adjustable spring 10 into a conical seating 7 in the outlet passage 6 from a storage chamber 2 one wall of which is formed by a flexible plate spring 3 and which is connected through a restriction 4 and a passage 5 to the pressure line, e.g. a pit prop compression chamber. In operation, when the valve 8 is closed the pressure in the chamber 2 is the same as that in the pressure line. As the pressure increases the wall 3 flexes upwardly until the pressure within the chamber 2 is sufficient to open the ball valve 8 against the force of the spring 10 and the frictional force between the ball and seat. The sudden disappearance of the frictional force gives the valve a high lift characteristic. The pressure within the chamber 2 falls and the wall 3 flexes inwardly and the valve re-seats. The ball 8 may be magnetic so that magnetic action tends to maintain it in its seat. In another example, Fig. 4, the ball valve 18 is loaded by a coiled spring 21 and by flexible plate spring 20 to seat on a member 19 carried by a flexible plate spring 17. As the pressure in the chamber 16 increases the plate spring 17 flexes upwardly taking with it the valve seat 19 and the spring 21 and causing upward flexing of the spring 20. When the spring 20 snaps over its dead centre position the ball valve is opened by the fluid pressure in the chamber 16 whereupon the spring 17 returns to its initial position. In another example, Fig. 6, the storage chamber 28 has a flexible wall 29, a restricted inlet 30 and is connected by a passage 31 to a cylinder bore 32 containing a piston 33 from which extends a rod 34 into a passage 36 having a seat 35 for a ball 37 loaded by a spring 38 which acts through a plunger 41. The bore 32 has an enlarged portion 32a and the piston has a flow passage 43 extending part way along its length. When the pressure in the chamber 32a is sufficient to raise the valve the resulting pressure drop across the piston causes upward movement of the piston and the rod 34 raises the ball 37 fully and allows direct flow of fluid via piston flow passage 43.

Title: Improvements in or relating to the manufacture of separable fasteners
IPC: B29D5/02
Filed: 1934-11-30
Abstract: 448,124. Sliding - clasp fastenings. CORNER, G. H. C., Mauber, Monmouth Drive, Sutton Coldfield, and LIGHTNING FASTENERS, Ltd., Imperial Chemical House, Millbank, London. Nov. 30, 1934, No. 34507. Addition to 391,146. [Class 44] The method of securing non - metallic elements to the tapes of sliding-clasp fasteners by cementing, gluing, or temporarily softening the jaw surfaces of the elements as set out in the parent Specification is modified by applying pressure during the affixing operation and preferably also heat. A tape with elements 1 frictionally held thereon is placed upon a slotted plate 10 to allow the lower edge of the tape 8 to dip into a solvent bath 9 and steam or water heated pressure members 12, 13 are moved against the legs of the elements ; a top presser bar 16 maintains the elements in position during this operation. For elements of synthetic resin the jaws are faced with celluloid by cementing an insert between the legs and then cutting out the middle portion. The elements may be secured by an adhesive containing rubber which is thus pressed into the material of the tape and vulcanized; the vulcanization is completed by heating in an oven.

Title: Improvements in or relating to a method of treating the surface of a semi-conductive body consisting of a selenide or a telluride of a bivalent metal
IPC: H01L21/06
Filed: 1955-12-02
Abstract: A noble metal layer is applied to a semi-conductive body of a selenide or telluride of a bivalent metal (noble metal is defined as a metal which is higher in the electromotive series than the bivalent metal) by contacting the body with a solution of a salt of a noble metal so that the noble metal precipitates on the body and the bivalent metal is dissolved.  The noble metal may subsequently be removed and a different noble metal applied as by evaporation. Bivalent metals referred to are Zn, Cd, Hg, Sn and Pb, and the noble metal may be Ag, Au, Hg, Pt or Rh.  The examples disclose the coating of CdTe and HgSe bodies, and salts used are AgNO3, AuCl3, PtCl4 and RhCl3: one example refers to the removal of an Au layer from CdTe by treatment with a KCN solution, and then coating with Ir by evaporation.  The semi-conductive body may be used to provide a rectifier, transistor, photo-conductive or photo-voltaic cell.

Title: Improvements in method of producing compacted folded stacks of paper tape and the product thereof
IPC: B65H45/20
Filed: 1934-12-04
Abstract: 439,391. Manifolding sheets. HAND, L. T., 6924, Ridge Boulevard, Brooklyn, New York, U.S.A. Dec. 4, 1934, No. 34815. [Class 16] [See also Group XVI] A stack of continuous, uninterrupted paper tape for use in recording machines is formed from a paper web by folding the web in zigzag fashion into equal coextensive folds, the edges of all of which are in alignment, the folds being delivered stacked and compacted by applied pressure to such a degree as to provide a substantially solid rectangular block having a hard edgewise surface on all four sides thereof. The web 8 passes from a roll 29, Fig. 2, over guide rollers to a roller 32 with which co-operates a circular cutter 33 which divides the web longitudinally into several strips, the severance being either complete or partial. The web then passes over further guide rollers, and, in the case of completely severed strips, the strips are separated somewhat by collars 53 on a shaft 36 and by longitudinally extending guides, before passing to indenting means 9 carried by rollers 6, 7, which are oppositely rotated and serve to indent the web so that it folds in zigzag upon a table 16. The table is slidable upon a guide 18 and its height is adjusted by rotating a worm 25 which turns a sprocket 23 over which passes one of a pair of chains 19, the other ends of which are attached to the table 16 and which also pass over sprockets 21 carried by a common shaft. The paper folds are compressed into a hard block on the table 16 by rotating helicoidal members 51, Fig. 3, which engage the two folded edges of the web and press each new fold down upon the pack. When the web is only partially severed, the tape widths can be detached after the complete block has been made. A plurality of webs including a carbon, wax, or other duplicating web may be formed into a block by passing the three webs in superimposed relation through the machine, the webs in this case being completely severed.

Title: The manufacture of wetting, sudsing, emulsifying and detergent agents
IPC: F21V21/02
Filed: 1936-12-18
Abstract: Wetting, emulsifying, and detergent agents are manufactured by treating saturated alcohols having at least eight carbon atoms in the molecule with a solid reagent prepared by reacting chlorsulphonic acid with a chloride or sulphate of ammonium or of a metal which forms a water soluble salt with the resulting alcohol sulphuric ester.  Both the formation of the solid reagent and the esterification of the alcohols may be effected in a ball mill or other mixing vessel provided with means for removal of hydrochloric acid and for cooling.  The product, if in acid condition is neutralized and may be purified to free it both from unesterified alcohols and from inorganic salts.  In examples, (1) sodium chloride or sulphate is reacted with chlorsulphonic acid and the product after being ground to powder reacted with alcohols obtained by hydrogenation of coconut oil or tallow; neutralization is effected with sodium carbonate; (2) the ester obtained by treating coconut oil alcohols with the chlorsulphonic acid-sodium chloride reaction product is freed from organic impurities by means of petroleum ether and is crystallized from ethyl alcohol. The use of the chlorides or sulphates of potassium, magnesium, cobalt, manganese, and nickel is mentioned.  Specification 479,553 is referred to.ALSO:Emulsifying-agents are manufactured by treating saturated alcohols having at least eight carbon atoms in the molecule with solid reagents, which are probably metal chlorsulphonates prepared by reacting chlorsulphonic acid with a chloride or sulphate of ammonium or of a metal which forms a water soluble salt with the resulting alcohol sulphuric ester.

Abstract: 467,586. Variable - speed epicyclic gearing. McGILL, H. Dec. 19, 1935, Nos. 35196/35, 2692/36, and 4845/36. [Class 80 (ii)] A speed-reducing train, including stepped planets 18, 18A and a final driven sun - wheel 9, is combined with a single planetary train such as 4, 2, 2A, 3, 17, controlled by mechanical or fluid speed-responsive means 4, adapted gradually to connect together two elements of the planetary train, so as to create the whole of the torque-reaction for producing drive from zero to synchronous speed. The trains are interconnected by a pair of freely-floating sunwheels 17, 17A permanently connected together. The speed-responsive means 4 may constitute a centrifugal friction or fluid clutch, but, as shown, is the inertia device described in Specification 422,432, wherein centrifugallyinfluenced masses in the driving planet-carrier 4, gradually clutch the planet-spindles 10 to the carrier, thereby restraining the planets 2, 2A from free rotation. The sun-wheel 3 is rigidly connected to the second planetcarrier 14, and this carrier may, as shown, be provided with a manual brake-band 13, which yields a positive reduced speed, or, if the planet-wheels 2, 2A are inverted, a reversed drive. In a modification, the stepped planets 18, 18A are freely mounted on the planetspindles 10, the sun-wheel 3 and planets 2 being omitted, and in a modification of this construction, the speed-responsive planetcarrier 4 freely floats on a shaftinterconnecting the sun-wheels 17, 17A, the planets 2A being driven by an annulus on the driving shaft. The first and second Provisional Specifications state that both the driving and the driven members are annuli, and the first Provisional Specification refers also to Specifications 438,987 and 449,784.

Abstract: 1,029,167. Hydrodynamic brakes. CATERPILLER TRACTOR CO. Aug. 28, 1964 [Sept. 13, 1963], No. 35299/64. Headings F2E and F2F. In an hydrodynamic retarder system for tractor-trailer vehicles a load cylinder 12 is in circuit with the hydrodynamic retarder 10 associated with the tractor vehicle such that when air under pressure is admitted through a line 15 via a valve 14 through a time delay and pressure valve means 18 pressure is increased in the hydrodynamic retarder circuit, the valve means 18 being closed when the pressure in the tractor hydrodynamic retarder circuit attains a predetermined value. Air from the valve 14 also passes through a line 19 to a relay valve 20 and through pressure valves 22 to control the load cylinders associated with the hydrodynamic retarders on the trailer vehicle. The valve 18 on the tractor vehicle is provided with a time delay mechanism in the form of a spring 28 which opposes movement to the left of a piston 27 to ensure a delay before the spool 24 is actuated, whereas the valves 22 associated with the trailer hydrodynamic retarders do not include a delay mechanism, thereby ensuring that the trailer hydrodynamic retarders are actuated a fraction of a second before the hydrodynamic retarder on the tractor vehicle to prevent jack-knifing of the tractor trailer combination.
