Title: Electric transducer
IPC: H01J17/30
Filed: 1956-11-06
Abstract: 822,574. Electric indicating systems. LION, K. S. Nov. 6, 1956 [Dec. 7, 1955], No. 33860/56. Class 40 (1). [Also in Group XL (a)] Sputtering of the internal principal electrodes in the discharge tubes of transducer systems as described in Specification 762,914, is avoided by positioning the auxiliary electrodes so as not to overlap the principal electrodes so that the principal electrodes are not immersed in the plasma of the discharge. In one arrangement, Fig. 1, the gas-filled glass tube 1 contains two internal principal electrodes 3 and 5 connected to output terminals 2 and 4. External auxiliary electrodes 6 and 7, spaced from the tube 1 by small air spaces 8 and 9, are connected to a source 10 of alternating current, preferably of radio frequency, which maintains in the tube 1 an ionized region (shown shaded in the Figure). The ionized region remains substantially localized to the left of the dotted line A-A. Relative movement between the tube 1 and the electrodes 6 and 7 produces a D.C. output at the terminals 2 and 4. In a modified arrangement, Fig. 2, the electrodes 6 and 7 are disposed on the tube envelope and a capacitor 11 or other variable impedance element is connected between electrodes 3 and 6 to vary the A.C. potential on electrode 6 relative to that on electrode 7. The variable capacitor 11 may be controlled by any desired physical change (e.g. a change in humidity) or movement to produce an output signal at terminals 2 and 4. A further variable capacitor may be connected between electrodes 4 and 6. The electrodes 6 and 7 are preferably shaped as part-cylinders, each surrounding about one-third of the periphery of the tube 1, but may alternatively be single wires or may be in the form of conductive paint painted or sprayed on the tube wall. In further modified arrangements the electrodes 6 and 7 are in the form of plates positioned inside the tube so that the electric field between them is at right angles to the plane formed by electrodes 3 and 5, and each electrode 6 and 7 is connected through a variable capacitor to each of the electrodes 3 and 5, or alternatively electrode 6 is connected to the movable plate of a differential capacitor connected between electrodes 3 and 5. In some applications one or more of the variable capacitors may be omitted or may be replaced by the stray capacitance between electrodes.

Abstract: 805,722. Change-speed control. BLOXWICH LOCK & STAMPING CO. Ltd. Feb. 15, 1957 [Nov. 7, 1956], No. 33957/56. Class 80 (2). [Also in Group XXXVII] In a vehicle gear control the gear lever is provided with a rockable knob, normally held in a central position by a resilient means, whereby movement of the knob causes wiping engagement of electrical contacts which close a circuit energizing means for disengaging a clutch. A gear change fitting coupled to the linkage for controlling a gear-box carries a tube 10 having a convex surfaced collar 16 secured thereto. A handle 13, of insulating material moulded on to a re-inforcing metal liner 14, pivotally engages the collar 16 at its inner end and is closed at its outer end by an insulating plug 26 carrying a slidably mounted convex faced metal button 28 with a secondary sliding contact plunger 30 in the button 28, both urged by springs 29, 31 into engagement with an insulated live contact 23 in the outer end of the tube 10. Rocking movement of the handle in any direction relative to the tube 10 wipes the button 28 and the plunger 30 transversely across the live contact 23 to engage an annular contact 20, connected to earth through the tube 10, and complete a circuit. The wiping action under spring pressure keeps the electrical contacts clean. Spring fingers 19 normally maintain the handle in a central position. In an alternative construction the plunger 30 is omitted and the button 28 is solid with an annular convex rib for engagement with the live contact on the earth contact.

Title: Shaping of upper components
Inventor: HAWKES SIDNEY
IPC: A43D11/00
Filed: 1962-09-05
Abstract: 1,001,583. Boots &c. F. HAWKES, C.N.V. ENGINEERS Ltd. Aug. 21, 1963 [Sept. 5, 1962], No. 33958/62. Heading A3B. Upper components, e.g. counters, vamps and whole shoe backs, are shaped by clamping the upper material around the area intended to be shaped, leaving this area unclamped and applying a controlled thrust to the unclamped area to stretch it to a desired contour. As described, a counter blank 100 is shaped by clamping it between two pairs of clamping plates 6, 7 and 8, 9. Plate 6 is fixed, plates 7, 9 are mounted together with a separator 14 between them and are pivoted to the machine frame at 15 and plate 8 is pivoted to the machine at 12. The plates are clamped together by flanges 25 on arms 27 engaging rollers 23 mounted on the top plate 8, clamping pressure being applied by a spring 32 through a bolt 30 screwed into a block 29 upon which the arms 27 are mounted. When the counter blank 100 is clamped in the machine a contoured head 18 on a stem 17 is moved forward by a piston and cylinder 4 to stretch and shape the end of the counter. Recesses 33 may be cut in the clamping plates 7, 9 to allow a differential stretching of the counter blank. The counter blank may be pre-conditioned e.g, by mulling or may undergo liquid- or heat-treatment during the stretching operation and for this reason the clamping plates on the contoured head 18 may contain heaters (not shown). In a modification (not shown) several such shaping devices are mounted on an intermittently rotating table, the stem 17 being moved forward by engagement with a stationary cam at the centre of the table.

Working-fluid supply ; motor power plant.-Separate or interconnected pairs of internal-combustion engines supply combustion products and steam either at different points on the circumference of the first stage of a turbine or at different stages. Each combustion chamber 2, Fig. 2, contains a piston 1 which actuates a piston 52 of an air compressor 5, from which air is delivered to a valve 11 controlling the inlet port 9 and actuated either by the air pressure or by a cam-shaft 17 which is driven from a bracket 19, Fig. 5, fixed to a rocking beam 8 connecting the pair of piston-rods 51, Fig. 2. Water is circulated through the turbine and the cylinder jackets and regenerators 24, 28, Fig. 7, through which the exhaust gases pass, by pumps 6 actuated from the piston-rods 51. The steam generated passes to a drum 25, which may be replaced by a boiler, and thence by pipes 14, 14a to inlet passages 141, controlled by a piston 111 on the shaft of the valve 11 and to a separate turbine nozzle 26, Fig. 2. Fuel pumped into the cylinder by a pump 21 actuated from the shaft 17 is exploded and forces the piston 1 downwards ; at the end of the stroke the gases pass through the port 3 to the turbine 41, compressed air enters through the port 9 while steam, admitted beneath the piston, assists the return of the piston by the rocking beam 8 due to the explosion in the second cylinder. At the end of the upstroke, the steam passes through the passage 3 to the turbine. When separate cylinders 2 are used, the instroke of the piston may be obtained by connecting the piston rod to a crank on a fly-wheel shaft or by having two cylinders in line, the pistons being connected by a rod.

Abstract: 836,661. Type-bar-making machines. FAIRCHILD CAMERA & INSTRUMENT CORPORATION. Nov. 8, 1957 [Dec. 24, 1956], No. 34895/57. Class 100(3) Driving-mechanism. Apparatus for controlling a typographical line-casting machine by means of a coded tape comprises first and second mechanisms responsive to special code signals in the tape before and after a sequence of unrequired signals not to be used for controlling the machine, said mechanisms actuating means to prevent the code bars from being set in accordance with the unrequired signals and means to speed up the advance of the tape while the unrequired signals are being sensed. In control apparatus of the general construction disclosed in Specification 747,233, the drive to the record-reader shaft 45. Figs. 1 and 6 is through the normal clutch 65 and one of two additional clutches 55, 56 on a shaft 57, respectively for normal and highspeed operation of the tape feed and record-reader. The timing shaft 176, Figs. 1, 6 and 8, carries two additional timer sections 181, 182. On sensing of the first special signals, the bars 115 are so set that an additional bail in the series 142 actuates contacts 151 and 154. The universal contact 154 causes energization of the magnet 186 to stop the record-reader and tape feed and of the relay 187 to lock the magnet 186 and disable the magnet 202 for the transfer cam shaft 50. The contact 151 causes energization of a magnet 172 to rotate timer section 182, whereupon closing of a contact 208 causes energization of a magnet 81, swinging a lever 73 to move the shaft 57 to the left and engage the high-speed clutch 56, and opening a contact 84 in the circuit of the magnet 202. Opening of a contact 195 causes de-energization of magnet 186 and relay 187, whereupon the tape is advanced at high speed, but the shaft 50 is not rotated because of contact 84 being open. On sensing of the second special signal, the setting of the levers 118 is such that a bail 91 having coded projections 89 is allowed to swing under the action of a spring 139, when permitted by a roller 138 on a lever 133 co-operating with a cam 137 on the shaft 45, so as to close contacts 94 and 95. Closing of contact 95 causes energization of magnet 186 and relay 187 to stop the record-reader and tape feed. Closing of contact 94 causes energization of a magnet 171 to rotate timer section 181, whereupon closing of a contact 216 causes energization of a magnet 82, swinging the lever 73 to move the shaft 57 to the right and engage the normal-speed clutch 55, and closing the contact 84. Opening of a contact 194 causes de-energization of the magnet 186 and relay 187, whereupon the tape is advanced at normal speed, and the shaft 50 is normally rotated. Reference has been directed by the Comptroller to Specification 703,870.
