Title: Generators of combustion products
IPC: F02C5/12
Filed: 1944-07-17
Abstract: 653,490. Air and gases compressing. ARMSTRONG WHITWORTH & CO. (ENGINEERS), Ltd., Sir W. G., MANSFIELD. W. P.. and WHITE, J. July 17, 1944,. No. 13634. [Class 8(i)] [Also in Groups XII and XXVI] Apparatus for generating combustion products under pressure for use in driving a turbine or other machine or as a jet for direct propulsion purposes comprises a combustion chamber in which an explosive combustion of a fuelair mixture is effected associated with a wave duct along which a pressure wave is propagated and which is so constructed that a part of the energy of the wave is first reflected as a " negative " wave to cause or assist the induction of a fresh charge and subsequently another part of the energy of the wave is reflected as a "positive " wave to compress the new charge prior to ignition, means being provided for leading away the gases produced to store or directly for doing work. As shown in Fig. 1, the combustion chamber has a water-cooled end cover 1 fitted with four automatic valves 2, serving for the admission of a fuel-air mixture from a carburettor jet 5, and a sparking plug 6 which is controlled by a contact breaker 8 actuated in accordance with the pressure prevailing in the combustion chamber by a plunger 14. Starting is effected by the detonation of a cartridge 17 fired by a pin 18 attached to a manually-operated striker 20. To the outer end 24 of the combustion chamber is attached a wave duct 25 which may be of any desired cross section and may comprise a divergent duct with a partly closed end, Fig 6, or separate closed and open ducts, Figs. 7 and 8, the closed duct being longer than the open one. When a divergent duct is used, the taper may be constant or vary along the length or it may be provided with steps. Fig 3 shows a modification in which the fuel nozzle 14a is supplied by a pump 11a through a pipe 12a, the air supply through ports 2a being controlled by a piston valve 1a subject, on its outer surface, to gas pressure transmitted through a conduit 7a connected to the main wave duct 8a. The operation of the fuel pump 11a is controlled by a plunger 15a subject to combustion chamber pressure. The generator may be arranged as a producer of high pressure combustion gases by completely closing the outer end of the wave duct and providing a discharge valve in the combustion chamber or at any point along the length of the duct. In a further embodiment, shown in Fig. 5, in which the generator is combined with an air compressor, a duct 1b is arranged in axial alignment with and on the opposite side of the combustion chamber 3b to the main wave duct 2b, this duct 1b being provided with inlet and discharge valves 4b, 5b for the induction and discharge of air. In this construction, reflection of the " negative " wave induces, through the inlet valve 4b, air of which only a small part is utilized in the combustion process, the remainder being compressed by the reflected " positive " wave and delivered through the discharge valve 5b to a suitable container or reservoir.

Filed: 1952-05-29
Abstract: 730,389. Casting concrete structures in situ. LIND & CO., Ltd., P., and HOLLAND, H. A. May 15, 1953 [May 29, 1952], No. 13719/52. Class 20 (2). Shuttering for concrete walls, more particularly walls of structures such as a cooling tower wherein the perimeter of the wall varies gradually as the height increases, comprises rectangular panels 11 retained in position by vertical members 1 supported solely by a previously built part of the wall 7, a gap between adjacent vertical edges of neighbouring panels 11 being filled by sheet metal strips 2 running the length of the inner faces of the vertical members and overlapping the inner faces of the panels 11, thus enabling the horizontal distance between neighbouring vertical members to vary as required by the shape of the structure. The strips 2 may be bent slightly in plan, Fig. 2, to be tangential to the curvature of the wall at the centre of the panels 11. The shuttering of a lift being concreted, is supported by the shuttering immediately below, which is left in place for this purpose, the vertical members of two such stages of shuttering being joined by a cleat 4 which permits the vertical members to be set at a small angle as seen in side view to enable the wall to curve in vertical profile. The lower edge of a panel 11 of a lift being concreted, is supported by the upper edge of a panel 11 immediately below and is located thereon by an upwardly projecting horizontal cleat 12 which is provided along the upper edge of each panel. The upper edges of the panels 11 of the lift being concreted, are held in place by wedges 14 driven downwards between the cleats 12 and crosspieces 9 secured to the vertical members 1. The shuttering may be used on both sides of the wall with the bolts 8 passing through vertical members 1 on opposite sides of the wall and through precast concrete distance pieces 10. The shuttering may be used on only one face of the wall. As an alternative to providing precast concrete distance pieces 10 the vertical members 1 on both sides of the wall may have cleats or vertical extensions bolted to them and be held apart in any suitable way. An alternative form of panel can be formed of vertical boards held together by the cleat 12 along the top and by a second horizontal cleat a short distance from the bottom. When the diameter of the tower decreases sufficiently, these cleats can be sawn through and a board removed.

[Class 19]  A mop of the self-wringing type comprises a rod-like handle, a stem carried by a bracket member and arranged transversley to said handle at its lower end and connected to said handle by said bracket member, sponge rubber or like soft resilient liquid-absorbent material surrounding said stem and means by which the absorbent material can be compressed along said stem to express the liquid absorbed therein. The device, Figs 1 and 3, comprises a housing 10 having a top wall, a rear wall, and two end walls 13 and 14. A rear projection 15 has a bore for a handle 17 or the projection could be shaped as a spigot to engage within a bore of a tubular handle. The wall 13 has a hole through which extends a tubular stem 19 fitted with a knob 20 at its outer end, while its other end is flared to form an abutment for a metal washer 22 fitted on to the stem. Another washer 23, on the stem, is disposed against the end wall 13. The stem is surrounded by blocks 24 of sponge rubber each having a hole enabling it to be slid on to the stem. The blocks may be moulded or otherwise formed with an impervious skin (not shown) extending around the top and sides. A guide rod 31 fastened to the end wall 14 extends within the stem thus supporting the latter. When wringing, the knob 20 is pulled outwards thus causing the stem 19 and washer 22 to move axially so that the blocks are compressed together. On releasing the knob the blocks resume their original shape and the stem returns to its normal position. The transverse stem may be connected by a linkage or Bowden wire with a lever or knob disposed at the top of the handle so as to effect the wring- ing operation without stooping. According to the Provisional Specification the guide rod may be attached firmly to one end wall of the housing and disposed within a hole in the other end wall, the stem being slidable on the rod and fitting snugly within the end hole.

Abstract: 707,580. Linear-dimension gauges. WALLEY, W. S. June 20, 1952 [June 15, 1951], No. 14237/51. Class 106 (2) A gauging appliance for indicating the desired positions at which sheets should be withdrawn from bales of wood pulp for inspection purposes, comprises a plurality of rules A of different lengths hingedly connected along their long sides B, each rule having a length one fifth of the predetermined height of the bales with which it is to be used, each scale being divided by markings indicating the positions at which the top sheet in successive bales of that height should be taken. Thus, for example, suppose that sample sheets are to be selected for removal from a number of bales of wood pulp all of height 24 inches. For this, the rule marked 4.8/24 inches is used. From the first bale the top sheet is selected as a sample for removal and the rule is then used by placing its upper edge D level with the upper face of this top sheet. At the position indicated by the numeral 6 a further sheet is selected for removal. The upper edge D of the rule is then placed on a level with the upper face of this second sheet and at the position indicated by the numeral 6 a third sample sheet is selected for removal. This procedure is repeated until five sample sheets have been selected for removal. On the next bale, the upper edge D of the rule is placed level with the top face of the bale and at the position indicated by the numeral 2 a first sample sheet is selected for removal. Measurements are then made as before, commencing from the surface of this initially selected sheet in the second bale, until five sheets have been selected. The process is carried on for other bales. If the bales were all of height 23 inches, then the rule marked 4.6/23 inches would have been used. In Fig. 1, the dark lines indicate the positions at which samples would be taken by the above method from six similar bales.
