Title: Improvements in or relating to brakes
IPC: F16D65/08
Filed: 1933-12-20
Abstract: 432,194. Internal-expanding brakes. BENDIX AVIATION CORPORATION, 105, West Adams Street, Chicago, U.S.A. Dec. 20, 1933, No. 35894. Convention date, Dec. 21, 1932. [Class 103 (i)] Internal shoe brake comprises floating shoes 1, 2, Fig. 1, engaging anchors 6 on one of which is pivoted an operating lever 10 connected by a link 9 to toggle links 7 connected to the shoes. The shoes are pivoted on toggle links 3 connected by a link 4 to an adjustable eccentric 5. The lining of shoe 1 is in two parts and the lining of shoe 2 has transverse slots to collect the dust. An annular chamber 151 on the drum is filled with ethyl chloride for cooling purposes. In a modified form a single link 7 is connected to one shoe and cams on the end of the other shoe. The drum is formed with an annular air chamber having an inwardly opening check valve through which air is drawn when the brake cools and outwardly opening check valve through which air is expelled when the drum is again heated by braking, this latter valve may be connected to the tyre valve to maintain the tyre inflated. One shoe is in two parts joined by a hinge and also by a strut of the material known under the Registered Trade Mark "Invar " which changes the curvature of the shoe to compensate for expansion of the brake drum. The other shoe has a sliding part 32, Fig. 7, carrying part of the friction lining which is held against a stop 35 by a spring 36. When the brake is applied in the forward direction of the vehicle the friction against the drum draws the part 32 away from the stop and the toe of the shoe towards the other part 31 of the lining lessening the self energizing effect.

Abstract: 366,194. Packing cases. JARVIS, G., 58, Sullington Road, Shepshed, Leicestershire. Nov. 29,1930, No. 36078. [Class 18.] In a collapsable packing case of the type comprising connected side walls capable of being folded together to lie flat and two separate end closure members one of which is releasably connected to the side walls, the lower edges of the side walls are bent inwardly into a U-section 1c, Fig. 2, to receive downwardly directed flanges 3a on the edges of the bottom 3 which is located wholly within the interior of the side walls. The edges of the bottom 3 may be bent into a #-section with the outer limb constituted by the flange 3a, and this limb may be longer than the other so that the bottom 3 is raised off the floor. The top 2 has upstanding flanges 2a down over which the upper edges 16 of the side walls can be turned, and the whole may be connected together by staples, stitching, lacing, &c. Creases 8 in the side walls enable various depths of the edges 16 to be turned down to adjust the size of the case. The side walls and their lower upturned edges may be connected together by staples 5, and portions 3b, Fig. 3, are cut in the flanges 3a to accommodate the staples. The portions 3b are cut sufficiently deeply to ensure that the bottom 3 rests on the bottom of the U-section 1c and not on the staples. To enable the various folds to be made, the upper and lower portions of the corner creases of the case are slit and squares are cut out of the corners of the closure members. The various flanges preferably extend right round the case. One or more wooden boards may be positioned adjacent the top and/or bottom to reinforce the case which is of fibre &c. board. Reference has been directed by the Comptroller to Specification 324,383, [Class 18, Boxes &c.].

Title: Apparatus for the underwater deposition of liquid bituminous material
IPC: E02B3/12
Filed: 1960-10-26
Abstract: <PICT:0903980/III/1> An apparatus for the underwater deposition of liquid bituminous material on the bottom of a waterway comprises a supply conduit provided at the end with at least one narrowed outlet nozzle, wherein the diameter of the largest circle that can be fitted within the cross-section perpendicular to the longitudinal axis of the nozzle is smaller than the diameter of the largest circle that can be fitted within the cross-section perpendicular to the longitudinal axis of that part of the supply conduit without the nozzle, but the diameter of the largest circle that can be fitted within the cross-section of the nozzle is at least 5 cm., the length of the nozzle measured along the direction of flow is at least 3 times the diameter of the largest circle that can be fitted within the cross-section of the nozzle, but not more than one-fifth of the length of the supply conduit, including the nozzle, which during operation is situated beneath the surface of the water and #q2 tot \sE 0,6fO1 wherein #q2tot = the total cross-sectional area of the nozzle or nozzles perpendicular to the longitudinal axis of the nozzle or nozzles; O1 = the cross-sectional area perpendicular to the longitudinal axis of that part of the supply conduit without the nozzle or nozzles; f = a shape factor.  This factor is 1 when the outlet nozzle or nozzles has or have a circular cross-section, and is derived from the formula <FORM:0903980/III/1> when the nozzle or nozzles has or have a rectangular or square cross-section, h being the short and b the long side of the rectangle or h and b being the side of the square, or, when the nozzle or nozzles has or have other cross-sections, is derived from the definition: 1/f = the quotient of the quantity of water at 15 DEG  C. passing under the influence of a pressure gradient causing laminar flow conditions through a nozzle of the relevant dimensions, and the quantity of water at 15 DEG C. passing under the influence of the same pressure gradient causing laminar flow conditions through a circular nozzle having the same cross-sectional area.  As shown, as the supply conduit 1 is moved along as indicated by arrow 6, so that the narrowed outlet nozzle 3 is close to the bottom 7 of the waterway the liquid bituminous material, fed into supply conduit 1 through funnel 2, flows from the nozzle 3 to form a dense coating layer 9 on the bottom 7.

Abstract: 1,040,096. Valves. FRANKENSTEIN GROUP Ltd. July 20, 1965 [Sept. 9, 1964], No. 36840/64. Heading F2V. A liferaft inflation valve has a cylindrical metallic body 1 housing a spring-loaded piston 3 with a rubber disc 5 which co-operates with a nozzle 6 to control flow from a supply hose 20 to a flaked outlet 8a; the inner end 8 of the latter is of small flow area in relation to the body 1. The body 1 has a moulded rubber covering 10 which penetrates holes 11 in a body flange 9 and is bonded to the inner surface of a gunwale 13. A vent hole 15 is provided behind the piston. The nozzle 6 is connected to the hose 20 by an elbow 19. The dimensions of the flow passages are such that the greater part of the expansion and cooling of the carbon monoxide supply gas takes place downstream of the piston 3 so mitigating against the formation of " snow " in the valve body during inflation at low temperatures.

Abstract: 1,177,875. Plastics bottles. APL CORP. 8 Aug., 1968 [6 Oct., 1967], No. 37926/68. Heading B8D. A bottle formed of flexible plastics material for storing beverages or the like under pressure, has a bottom wall 16 which is at least partly concave as seen from outside the bottle and an annular rim or heel 14 which integrally connects the side wall 12 of the bottle to the bottom wall 16, the bottom wall 16 being formed with reinforcing ribs 18 which project from the outside surface of the bottom wall 16. The ribs 18 are arranged to cover the bottom wall 16 symmetrically to define a concavity at the centre 20 (Fig. 1, not shown) thereof, at least some of the ribs extending in a direction substantially towards the centre. Outward flexing of the bottom wall under pressure of the contents is thus eliminated. The ribs 18 may be arranged in a formation of regular polygons, e.g. hexagons, or alternatively may extend radially from the centre to the periphery of the bottom wall (Fig. 5, not shown). The surface profile of the ribs may be formed with undulations (Fig. 9, not shown), and the ribs may extend into the side wall of the bottle. These ribs (24d) which extend into the bottle side wall may be replaced by similarly situated grooves 70e (Fig. 11, not shown). The bottle is adapted to be made by conventional injection and injection-blow moulding apparatus and methods.
