Abstract: 1375867 Valves; electrically-controlled brake - pressure - reducing valves GIRLING Ltd 30 May 1972 [25 June 1971] 29825/71 Headings F2F and F2V A valve for use in an hydraulic braking system, comprises inlet, vent and working ports 15, 31 and 41, respectively, two interconnected stem members 21, 26 the terminal portions of which are formed into tapered valving members, a permanent magnet 12, and a cup-shaped member 36, 37, the latter being coupled to move with the stem members and having a coil, not shown, wound around its skirt portion 37. The two stems have their adjacent portions 23, 24 so dimensioned and so secured relative to each other that the stems are allowed a relative radially directed displacement but are restrained against any relative axial displacement. This is said to remove the requirement of having bores 17 and 27 perfectly aligned. When incorporated in the braking system, the valve attains the position shown if the brakes are applied normally. Accordingly, the working port 41 is fed from port 15. However, when the deceleration of a braked wheel exceeds a predetermined value, a sensor sensing such deceleration emits a signal which is fed to the coil carried by skirt 37. Thus, the coil becomes energized and so the valve attains its opposite operative state wherein port 15 is isolated and ports 31 and 41 are in communication with one another. As a result, the braking pressure supplied to the actuator is initially cut-off and subsequently the braking pressure is relieved by a drain-back to the vent 31. Upon the braked wheel deceleration being reduced, the signal supplied to the moving coil is cut-off and the valve reverts to the state shown. In a modification, envisaged but not shown, the stem members 21, 26 act as push rods which project through their respective bores 20, 30 and which are selectively engageable with valve members in the form of balls spring-urged into engagement with the outermost portions of bores 20 and 30.

Title: Improvements in and relating to a method of and device for producing laminated materials
IPC: B29C48/91
Filed: 1946-10-07
Abstract: 624,716. Compound sheet materials. BARNARD, R. H. Oct. 7, 1946, No. 29911. [Class 140] A method of making laminated materials comprises the steps of melting material adapted to be drawn into fibres, passing it through a plurality of serially-arranged groups of small apertures and collecting the exuded material in a continuous process by placing the exuded material of one group as a layer on the layer from the preceding group. The layers may then be subjected to pressure. Referring to the drawings, a melting chamber 10 has the lower portion subdivided into a number of drawing chambers 11, 11a, 11b and 11c. The material 11, e.g. glass, is maintained at a level above these chambers by a feeding mechanism which starts up when a circuit is broken by the level of the molten material dropping out of contact with the lower end of an electrode 19 and feeds material via hopper 17 over wiers 16 into main chamber 12. Any standard feeding mechanism may be used, but that described in Specification 610,564, [Group XXIII], is preferred. The melting chamber is heated by coils 23 and each drawing chamber by coils 24. Each of the drawing chambers is provided with a plurality of small apertures 13, 13a, 13b and 13c through which the molten material is exuded, the apertures may be of the same or different sizes, Figs. 2 and 4. Pressure may be applied to chamber 18 through conduit 22. Beneath and to each side of each row of apertures are high-pressure air conduits 25 and 26 provided with discharge outlets 27 and 28 directed towards one another. The air streams from these pick up the molten material and draw it into fine fibres which are collected in chambers 29, 29a, 29b and 29c, and then discharged on to a conveyer belt 20. The first layer may be delivered directly on to the belt or on to a collection sheet, e.g. a sheet of paper or felt, and a similar sheet may be placed on the topmost layer. The laminated mats 35 may each pass between hoods 36 and 37 which slightly heat it to cause the lamina to adhere together more firmly. Fig. 3 illustrates a modification on which the heating means 46, 46a, 46b may be applied in between formation of each layer and in which moisture-proof material, e.g. coated paper or cellophane supplied from rolls 54 may be placed between the laminµ. Spray heads 55 may supply adhesive materials to cause the laminµ to adhere to the vapour-proof material and synthetic resins may be sprayed on the mat from spray head 53. Fig. 5 illustrates a modification in which 61 and 61a are the melting chambers, 62 and 62a the heating hoods and in which rolls 63 and 63a are provided to compress the layers after they have been heated. A knife 64 cuts the sheets into lengths. The fibrous materials may be laid on a sheet 65 treated with adhesive 66 from head 67.

Abstract: 652,146. Making belts. GOODRICH CO., B. F. Nov. 26, 1948, No. 30710. Convention date, Dec. 18, 1947. [Classes 83 (ii) and 83 (iv)] [Also in Group XXIV] Jointing by stamping.-A spliced transmission or conveyer-belt comprises a number of tension-resisting members 12, 13 extending longitudinally in pairs therein and with the opposed ends of each longitudinally-aligned pair inserted in a ferrule 25, the members being of substantially equalized tautness in the belt by virtue of a preliminary slippage while under tension in frictional-engagement with the ferrules and being attached permanently to the ferrules in the equalized condition. Opposed ends 10, 11 of the belt to be spliced are secured in clamps 15, 16 connected by screws 20, 21 which have threads of opposite hand on opposite ends thereof so as to permit adjustment of the distance between the clamps. The overlapping ends of the members 12, 13 are cut to length at points staggered along the length of the splice so that interference does not occur when the ferrules 25 are swaged tem-. porarily by means of the hand tool 26 shown in Fig. 2. The ends of the belt are then tensioned in the clamps 15, 16 by operating the screws 20, 21 so as to effect equal tension in the members 12, 13 before being released from the clamps and applied to a press, Fig. 5, for swaging the ferrules 25 into non-slipping engagement with the members 12, 13. A support 38 locates the ferrules 25 in relation to swaging jaws 34, 35 in the press which has pistons 30, 31 connected to the jaws and operated by an explosive cartridge fired by a pin 37. The latter operation may be replaced or supplemented by welding, brazing, or soldering the ferrules to the members 12, 13.

Title: Fluid control valve actuating structure
IPC: F15B17/00
Filed: 1960-09-06
Abstract: 902,652. Fluid-pressure brakes. BENDIX CORPORATION. Sept. 6, 1960 [Sept. 28, 1959], No. 30732/60. Class 103 (1). [Also in Group XXIX] A fluid-pressure servomotor, e.g. used in vehicle braking systems, has a control valve B and hydraulic actuating means A therefor which control the position of a spring-loaded piston C connected to a fluid piston D that displaces fluid into the brake cylinders. In the inoperative position the parts are in the position shown, the piston C being vacuum suspended. Upon an increase in hydraulic pressure at a port 10 and hence in a chamber 66 a diaphragm 78 is deflected and moves rightwardly on inner and outer pistons 60, 64, respectively, in the actuating means A whereupon a supported closure 44 on a diaphragm 40 in the control valve B is seated upon a member 50 A further pressure increase in chamber 66 results in unseating of a closure 52 which is rigid with member 50; atmospheric air can then enter a chamber 26, via a filter 30 and a chamber 28, and act upon the left side of the piston C to move the latter. Air pressure in the chamber 26 resists further movement of diaphragm 40 and inner piston 60 connected thereto. Any further increase in pressure in the chamber 66 causes the outer piston 64 to abut a stop 72 and the diaphragm 78 to fold up against the end of this piston and so gradually diminish the effective area of the diaphragm 78 which force upon the inner piston 60. The force exerted by the diaphragm 78 is divided into two parts, one of which is transmitted to the inner piston 60 and the other to the outer piston 64. The manner in which this face is divided depends upon the unsupported area of the diaphragm out of engagement with the piston 64, the end of which is provided with an annular raised portion 76. As the diaphragm is pressed into engagement with the whole of the end surface of the piston 64, the force exerted on the control valve B is gradually reduced to that due to the pressure in chamber 66 acting only over the part of the diaphragm 78 which is directly abutting the end of the inner piston 60. In a modification, the outer piston is dispensed with. Specification 788,587 is referred to.
