Title: Improvements in or relating to machines organised for applying pressure to the bottoms of shoes
IPC: A43D25/06
Filed: 1952-05-16
Abstract: 727,048. Shoe-bottom presses. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). May 18, 1953 [May 16, 1952], No. 12385/52. Addition to 623,295. Class 17 (1). A machine in accordance with claim 3 of the parent Specification has means operable automatically to cause the pressure of the fluid acting on the relatively large area to be relieved after a predetermined time. The means for initiating the shoe bottom 'pressing operation includes two manually operated members which must be operated simultaneously. In a machine having a pair of work pressing stations the work may be pressed concurrently in the two stations, and the predetermined time after which the pressure is automatically relieved may be of different extent at one station from the other. The machine shown has two sole attaching stations each including a pad box 12, toe and heel abutments 20, 22, a fluid pressure operated motor having small and large interconnected pistons 42, 38, 42<SP>1</SP>, 38<SP>1</SP> in cylinders 44, 40, 44<SP>1</SP>, 40<SP>1</SP>, a treadle 24, 24<SP>1</SP>, a cylinder control valve 108, 108<SP>1</SP>, a pressure selector valve 110, 110<SP>1</SP>, a timing control valve 112, 112<SP>1</SP>, a timing valve 114, 114<SP>1</SP>, and a treadle controlled valve 116, 116<SP>1</SP>. A pump 68, low pressure reducing valve 74, pressure regulating valve 76, relief valve 78 adjusted by screw 94, valve 34, valves 26, 28, accumulator 194, and station selector valve 206 are common to the two systems. A lasted shoe on a last on a pad box 12 is raised to engage the toe and heel abutments 20, 22, by operation of the associated treadle 24, 24' which causes fluid to pass to cylinder 44, 44', and substantial pressure is thereafter applied to the work by the simultaneous operation of the two knobs 30, 32 of valves 26, 28 by the two hands of the operator, thus ensuring that a hand of the operator cannot be pressed between the pad box and abutments. The duration of the pressing operation is determined by an adjustable needle valve in the timing valve 114, 114<SP>1</SP> which regulates the flow of fluid from that valve. The operator may cause the pad box to descend immediately without waiting for the action of the timing valve, e.g. if he wishes to readjust the work, by actuating valve 34 through the knob 36. Members 190, 190<SP>1</SP> of valves 26, 28 must be held down for a sufficient time for piston 198 of the accumulator and member 130 of valve 110 to be moved in order to obtain heavy pressure on the work and, to prevent rapid return of members 190, 190<SP>1</SP>, valve members 226, 226<SP>1</SP>, having small ports therethrough, and springs 228, 228<SP>1</SP>, are fitted to the ends of the valve chambers to apply a dash-pot effect. One station may be operator while the work at the other station is under pressure. Specification 703,274 is referred to.

Abstract: 1,135,238. Drying. CRYODRY CORP. 22 March, 1966, No. 12611/66. Heading F4G. [Also in Divisions A2 and H5] Energy is radiated into a microwave heating chamber from substantially the whole length of a waveguide extending along the chamber. The waveguide has a number of slots, e.g. slots 57 in waveguides 54, forming an aperiodic array. The waveguide may be circular (as shown) or rectangular and, in the latter case, the slots may be in a broad or a narrow wall. Axial, transverse or oblique slots may be used. The slots may contain dielectric, hermetic seals or may be open, in which case the waveguide may be used to introduce a controlled atmosphere into the heating space. In the example shown, a product to be dried (e.g. onions, wood-chips, potato flakes, citrus powders, apples or chemicals) falls from inlet 39 to outlet 41 past slotted waveguides 54. In a further example (Fig. 1, not shown), products (18) to be heated pass on a conveyer (19) through a conductive microwave heating tunnel (12) along the top of which a slotted waveguide (23) extends parallel to the axis of the tunnel. Transverse wave reflectors (28) extend from the top of the tunnel between the slots. Each end of the tunnel has an annular water conduit (17) with a dielectric inner wall (14) for preventing escape of wave energy.

Abstract: 514,686. Thermionic valves. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. April 28, 1938, No. 12661. Convention date, April 28, 1937. [Class 39 (i)] In a mixer valve imperforate, positivelybiassed electrodes are placed between the signal control grid and the oscillator control grid, these electrodes receiving electrons from the main stream or streams which may be repelled when the oscillator grid swings negative ; this prevents signal control grid current. As shown in Fig. 1, between the first control grid 11 and the second control grid 13 and in line with the support rods is disposed a pair of auxiliary electrodes 17, at a higher positive potential than the intermediate screen grid 12. An outer screen grid 14 and a suppressor grid 16 are disposed between the control grid 13 and anode 15. In a modification, the auxiliary electrodes may comprise channel-shaped members 42 enclosing the ends of and electrically connected to the screen grid 37. The cathode 35 is rectangular with emissive material only on the sides from which the electron streams depart. The wires of the control grid 36 are parallel to these faces. The valve may have a metal envelope. In a further modification, the second control grid has two additional support rods 45 opposite the coated faces of the cathode; these assist in the repulsion of the electrons towards members 42. Specification 439,082 and U.S.A. Specification 1,896,780, are referred to. Reference has been directed by the Comptroller to Specification 471,411.
