Title: Improvements in or relating to servo-assisted brake-operating apparatus
Inventor: EDGE STANLEY HOWARD
IPC: B60T13/24
Filed: 1954-03-19
Abstract: 752,370. Fluid-pressure brakes. CLAYTON DEWANDRE CO., Ltd. Feb. 23, 1965 [March 19, 1954; June 21, 1954], Nos. 8154/54 and 18182/54. Class 103 (1). In order to make the air control valves more sensitive to low hydraulic pressures in pneumatic servo units for hydraulic brakes of the kind described in Specifications 687,658, 693,842, and 709,017, the valve is provided with large and small pistons 1 and 2, such that initially the hydraulic pressure acts on the whole face of piston 1 and moves the piston 2 by thrust through the spring 11, but when such pressure has increased sufficiently to compress spring 11, the valve 16 is raised off its seat and the pressure acts directly on the small piston 2. The passage 10 leads through the intermediate hydraulic cylinder to the brake cylinders. In an alternative embodiment, shown in Fig. 3, pressure from piston 1 is applied to piston 2 mechanically, the spring 24 for valve 23 in the piston 1 taking abutment on a ring 20. Specification 751,375 also is referred to.
Patent GB-1041172-A (GB)
Title: Wound healing compositions and methods
IPC: A61K35/32
Filed: 1963-02-28
Abstract: Cartilage preparations for use in healing wounds are obtained by subjecting cartilage to a proteolytic treatment and grinding the cartilage, before or after the proteolytic treatment, in the substantial absence of oxygen or in the presence of an antioxidant to a finely divided state.  Preferably, the cartilage is defatted before the grinding step.  The cartilage is preferably obtained from animals not over six months old, the most effective source generally being foetal skeletons.  The proteolytic treatment can be effected with a proteolytic enzyme such as an acid-pepsin solution.  The final product generally has a particle size not exceeding 40 microns. Active woundhealing extracts may be obtained from the cartilage product by treating the latter with aqueous solutions of ammonia, urea or various salts having a pH of 6.5 to 10, preferably in the absence of oxygen or in the presence of an antioxidant.  The aqueous extracts may be concentrated in vacuum or spray-dried or freeze-dried.  The activity of the prepared cartilage is increased by exposing it to irradiation of wavelength not greater than 4000  , e.g. UV light.  A synergistic effect is obtained by admixing the cartilage product with growth hormone or tung oil.  The product may be administered in the form of tablets, capsules, suppositories, ointments, salves (based on aqueous gels, for example, of aluminium hydroxide, kaolin, silica, methylcellulose, alginates, gum tragacanth, gelatin, gluten, casein, polyvinyl pyrrolidone or dextran), solutions, aqueous suspensions, oily suspensions, emulsions, sprays or incorporated with surgical gauze.  Blood, blood plasma or a plasma substitute, e.g. polyvinylpyrrolidone or dextran, may be used as an extending agent.  In one Example (No. 14), pepsin-treated, ground cartilage is held, in powder form, between layers of surgical gauze and held through bandages to an unsutured wound.  In another Example (No. 22), the cartilage is put into the form of enterically coated tablets.

Title: Improvements relating to apparatus and methods for constructing underground concretepipes or land drains in situ
Inventor: EDE AINSLEY NEVILLE
IPC: E02F5/10
Filed: 1951-04-09
Abstract: 713,256. Land drains. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 9, 1952 [April 9, 1951], No. 8193/51. Classes 6 (1) and 33. [Also in Group X] To form land drains in situ, there is mounted on a mobile frame 11, to be moved vertically and about a transverse axis by jacks 36 and 50, an apparatus comprising a mole plough, an extruder carried or towed at the rear of the plough, and means for forcing concrete under pressure through the extruder and around the vibrated core thereof to form an extruded concrete pipe lining the tunnel made by the plough. Concrete is raised by a screw conveyer from a hopper 62 into a hopper 13 from which it is gravity-fed down through the hollow coulter 12 supporting the plough to a helical screw positioned behind the plough. The concrete is urged rearwards by the screw 17 and is extruded through the annular space 23 between the enlarged end 22 of the tubular body 15 of the plough and a longitudinal vibrating core 21 to form a continuous pipe. To prevent clogging of the concrete as it passes down the coulter, a vibrator unit is connected to the walls of the coulter or to an elongated plate extending down the inside thereof. The core is hollow and contains a mechanically, electrically or fluid-operated vibrator. Continuous or discontinous openings in the concrete lining are formed by various forms of perforating tool mounted on or in the core 21, and a helix of reinforcing steel wire can be incorporated in the lining, the wire emerging from an aperture in the core 21. The wire is automatically paid out at a rate depending upon the rate of advancement of the machine by feed means within the core which may tow a second core behind it. The depth of the mole can be altered to meet any variation of ground contour by a control cam mounted on a wheel of the vehicle frame. When one drain crosses the bore of another drain its bore is reduced by a temporary increase in the rate of extrusion of the concrete with which may be combined a wetting agent, a cement dispersing agent, a gas-forming material or compressed air.

Title: Improvements in or relating to press-button devices
IPC: G05G7/08
Filed: 1964-02-27
Abstract: 1,016,945. Press-button devices. PHILIPS ELECTRONIC and ASSOCIATED INDUSTRIES Ltd. Feb. 27, 1964 [March 1, 1963], No. 8218/64. Heading E2A. [Also in Division B4] A press-button device for moving an element 2 from an inoperative to an operative position and locking it in the latter comprises a pressbutton 1 for moving the element 2 between the two positions, a spring 12 for biasing the element 2 in the inoperative position, a second spring 13 for returning the press-button, a locking member 4 which engages the element 2 in the operative position, and a pawl 7 pivotally mounted on the locking arm 4 so as to project in the path of the press-button, the pawl being free to pivot out of this path when engaged by the press-button on its return movement but being restricted from pivoting when engaged on the forward movement thereof, and the press-button and the pawl being constructed to co-operate with one another with a cam action during the latter engagement so that the pawl is lifted by the press-button thus moving the locking arm 4 out of engagement with the element 2. The element 2 is moved to the operative position by pushing the press-button 1 inwards and on reaching this position, the element 2 is engaged by an abutment 6 on the locking member 4, the locking member being held in this position by a spring 14. During the return movement of the press-button, a projection 3 thereon engages the pawl 7 which pivots out of its path. When the button 1 is pressed again, the projection 3 engages the pawl in a direction in which it cannot pivot due to an abutment 9. Due to the inclined surface of the pawl, the abutment slides down this surface causing the locking arm to pivot about the axis 5 against the action of the spring 14 and thus releasing the abutment 6 from the element 2. The element 2 can thus return to the inoperative position under the action of the spring 12.

Abstract: 1,098,922. Continuous casting. UNITED STATES STEEL CORPORATION. Feb. 25, 1965 [March 6, 1964], No. 8234/65. Heading B3F. A starter bar 26 is withdrawn from a mould 20 and descends through guide rolls 30, water sprays from nozzles 34 and pinch roll stands 40, 42 before detachment from the casting which is then deflected by a bending roll mechanism 60 and, with its core still molten, passes into a curved guide frame 90 for further deflection by rolls and cooling by sprays, Figs. 4, 5 (not shown), to solidify the core. The starter bar 26 descends through the assembly 60, after detachment from a chill plate (which remains attached to the casting) by an air-operated striker-arm 54 set off by an operator or automatically by a feeler arm 58 abutting the edge of the starter bar and operating a switch 59. A carriage 80 lowers the bar 26 to a conveyer 84 for re-use. The casting passes between rolls and spray nozzles, Figs. 2, 3 (not shown), of the bending assembly 60 while a part 64 of the mechanism, pivoted at 66, is swung slightly to bend the casting which then enters the frame 90. This guide frame 90 has at the top a portion 92 movable to allow the detached starter bar to be lowered before the casting is received. In modifications of the guide frame, Figs. 6-8 (not shown), the whole top portion or one side of it can be translated laterally, or the top is formed by a flexible string (of sections bearing pairs of rolls and linked together) which can be allowed to dangle vertically, to allow lowering of the starter bar. The starter bar (26), Figs. 9-11 (not shown), has a slot (366) of T-section across its breadth and a plate (376) slides in it with a keel portion (384) in the upright of the T. Keyhole slots in the plate (376) coacts with flattened necks (354) of pins welded to the chill plate (24) and passing through holes in the top of the bar so that in one position the plate (24) is retained and in another it is released. The heads of the pins are embedded in the end of the casting. The pinch rolls 40, 42 may be driven at different speeds to aid release of the bar and to convey it away quickly from the casting. The bar described in Specification 1,088,597 may be used. Specification 1,088,598 is referred to.
