Title: Improvements in device for upsetting metal
IPC: B21D11/08
Filed: 1944-02-28
Abstract: 575,086. Upsetting and stretching machines. ENGINEERING & RESEARCH CORPORATION. Feb. 28, 1944, No. 3632 Convention date, Oct. 28, 1943. [Class 83 (iv)] In a machine for upsetting sheet metal having two pairs 2, 4 of pivoted jaws and means for closing the jaws on the work, the upper jaws each hang from a pivot 6 freely and have a convex working face 8 whereof the lowest part is nearer the other jaw 2 than is its pivot 6 and the lower jaws 4 support the work and are each free to move towards and away from the other. The upper jaws 2 are mounted by parallel pivots 6 on a head 5 which can be rapidly reciprocated by a crank 12a. They are pressed apart by an adjustable spring 9 to a position limited by plates 11. The lower jaws 4 may be similarly mounted on a bed 30 which is vertically adjustable by a wedge 34 and screw 36. The gripping pressure causes jaws A to move towards the jaws B. The faces of the lower jaws are similar, but they are flat at the parts the work C rests on. In a modification, the lower jaws, instead of being pivoted, rest on anti-friction rollers 44, Fig. 4, and are pressed apart by a spring 46. The Specification as open to inspection under Sect. 91 comprises the statement that the invention may also be used for stretching. This subject-matter does not appear in the Specification as accepted.

Title: Apparatus for automatically weighing and bagging material such as coal
IPC: B65B1/32
Filed: 1948-02-09
Abstract: 657,418. Filling-machines. NATIONAL COAL BOARD, GREEN, W. A., and HILTON, F. E. Feb. 9, 1948, No. 3667. [Class 94(i)] [Also in Groups I, XVIII and XXX] In a coal bagging plant, an automatic feed weigher, of the kind in which the bulk feed is made volumetrically'by a measuring box, located at the top end of a shoot the lower end of which carries means for holding the open mouth of a bag. Coal is fed down a shoot 24, Fig. 2, into a hopper 28 located above the automatic feed weigher 33, part of the supply of coal being diverted through a screen 25 into a shoot 26 which terminates in a vibrating shoot 35 forming the dribble feed. The main charge is measured in a box 29 having top and bottom gates which are operated by pneumatic cylinders 58 and 65 through a valve 97 which also controls a bag clamping mechanism and is operated by a fool pedal 86 and hand-lever 90 through a linkage 91, 92, 93, 94 95. This linkage also controls the weigh beam relieving mechanism 99. The top gates of the measuring box comprise a pain of reciprocable elements 43, Fig 4, the trunnions 55 of which are engaged by links 56 which are operatively connected to a pivoting link 57 connected to the piston rod 60 of the pneumatic cylinder 58. These gates have rigid fingers 52, and spring- loaded fingers 53 so arranged that a rigid finger in one gate is opposite a spring finger in the other thus ensuring that the gates are not held open by large lumps of coal. The lower gates which are of the normal hinged type and are operated by the pneumatic cylinder 65, have the curved cutoff plates arranged eccentrically with the pivotal axis of the gates so that coal held above the gates tends to force them apart. After fitting a bag to spout 37 pedal 86 is depressed and, sequentially, the weigher is unlocked, the vibrator on shoot 35 is energized, the bag clamps are closed, gates 32 are closed, gates 43 are opened and the box fills. On attainment of the predetermined weight of material in the receptacle of weigher 33 the vibrator stops and the weigher discharges into the bag which is then transported on a conveyer 38 to a neck stitching machine (not shown), and thence by further conveyers to a loading station. Next the operator raises lever 90 so sequentially resetting pedal 86, locking the weigher, opening the bag clamps, closing the gates 43, opening the gates 32 and dumping the next bulk feed into the weigher ready for the next cycle of operations. Bag clamping means. - The bags are clamped on the bottom of the outlet spout 37, Fig. 12, by arms 68 which are pivoted at 67 and carry rollers 83 contacting cams 82 which move the arms from the position shown on the right of Fig. 12 to that shown on the left. The cams are reciproocated by a pneumatic cylinder 80, Fig. 11 (not shown). Guards (not shown) are provided to prevent injury to the operator.

Title: Improvements in or relating to cathode-ray or the like apparatus for reproducing television images
IPC: H01J29/00
Filed: 1947-02-07
Abstract: 648,823. Cathode-ray tubes. COMPAGNIE GENERALE DE TELEGRAPHIC SANS FIL. Feb. 7, 1947, No. 3718. Convention date, Feb. 9, 1946. [Class 39 (i)] In a cathode-ray tube for the reproduction of a television image, the electron beam is scanned over a gas-tight diaphragm F, Fig. 6, separating the tube from a compartment V filled with a gas. Such an acceleration is imparted to the beam, and the diaphragm is made of a metallic or semi-insulating material of such thickness that the beam traverses the diaphragm and directly produces a glow by impact on the gas. The gas is at a relatively high pressure, for example exceeding one atmosphere in order that the luminous glow is confined to the point at which the beam penetrates the diaphragm. The diaphragm is realized so as to mechanically withstand the gas pressure. The gas chamber V is provided with a light-transparent glass G. A first electric system L1, L2 gives by scanning through the fields M1, M2 an intermediate image I<SP>1</SP>. The lens system V0, V1 accelerates the electrons to give the final image I2. The diaphragm may be of aluminium or of plastic material reinforced by a metal grid consisting of steel strips or wires. The grid may comprise a mesh or parallel wires. The plane of the bars of the metal grid may be directed towards the axis of the tube, Fig. 3d, so that the beam is not too greatly intercepted as the angle of the beam increases. The diaphragm may be goffered on one or both sides, and may be moulded on to the reinforcing grid so as to cover the grid wires, Fig. 4b. The diaphragm may be metallized on the face directed towards the electron beam or more particularly on the thicker parts of the goffering. The gas may be hydrogen at a pressure of five atmospheres, and examples of the thickness of the diaphragm and dimensions of the reinforcing grid are given. U.S.A. Specification 1,907,507 is referred to in connection with the construction of the diaphragm. For colour television, several cathoderay tubes, each employing a gas luminous with a different colour, may be used by superposing their projections on a common screen. Four gas compartments side by side, may comprise the screen of a single cathode-ray tube.

Title: Improved hydrodynamic torque converter
IPC: F16H61/56
Filed: 1958-02-05
Abstract: 814,112. Controlling vehicles. GENERAL MOTORS CORPORATION. Feb. 5, 1958 [March 6, 1957], No. 3744/58. Class 79(5) [Also in Groups XXIV and XXIX] The blades of the axial flow reaction member of a hydrodynamic torque converter for a vehicle are angularly adjusted by means dependent on the position of the accelerator. Each blade 30 can be rotated about a shaft 92 whose inner end forms a crank shaft 226 located in groove 228 in piston 230. Chamber 234 is open to the pressure in the converter circuit, and a restricted passage 238 admits liquid to chamber 232. The pressure in chamber 232 together with the force on the reactor blades 30 due to the movement of liquid in the converter chamber is normally sufficient to overcome the pressure in chamber 234, and piston 230 is maintained in its left-hand end position, so that the blades 30 are in the position in which torque conversion is least. The chamber 232 may be exhausted by movement to the right of tube 240 when liquid may flow via tube 240 and lines 242, 244, 246 to exhaust. The piston 230 then moves to the right until it again blocks the opening of tube 240. The position of tube 240 is determined by the pressure in chamber 262, which depends on the position of the accelerator 356 (Fig. 4). When accelerator 356 is depressed, spring 354 causes valve 350 to move to the right and admit pressure liquid from line 280 to chamber 262 via lines 268, 266 and 264. Chamber 360 is also connected to line 268, when sufficient pressure has built up, the pressure in chamber 360 moves valve 350 to the left against spring 354, blocking line 280. Specification 750,788 is referred to.
