Abstract: 410,549. Valve circuits for wireless reception. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and SMYTH, C. N., c/o General Electric Co., Wembley, Middlesex. Dec. 22, 1932, No. 36312. [Class 40 (v).] A muting device in a super-heterodyne receiver comprises a circuit so sharply tuned to the intermediate frequency that the set is inoperative unless the frequency about which the frequencies in the output of the first detector are centred differs by less than 1000 cycles from the intermediate frequency for which the set is designed. Preferably the tuned circuit comprises a piezo-electric crystal 5 tuned to the intermediate frequency, in series with a balancing condenser 6 shunting a tuned circuit 3, 4 fed from the first detector. When there is no output (from the first detector) having the intermediate frequency, the anode current of the triode section of the diode-triode 12 flows through the resistance 15 biassing the audiofrequency amplifier 17, fed from the second detector, to make it inoperative. When the intermediate frequency is fed to the circuit 3, 4, crystal 5 oscillates and current flows through the diode 7, 9 to set up a potential across resistance 8 which alters the bias on the grid 10 so that the anode current from the diodetriode ceases, thereby removing the prohibitive bias applied to valve 17. A resonance indicator of known kind may be included in the tuning control of the set. Specifications 379,608 and 395,569 are referred to.

Abstract: 1,036,487. Welding by fusion. AIR REDUCTION CO. Ltd. Sept. 11, 1964 [Sept. 13. 1963], No. 37286/64. Heading B3R. In arc welding using a continuously fed consumable electrode, the arc is initiated by retracting the end of the electrode by flexure of the electrode guide when the electrode contacts the work. Closure of switch 50 connects up a welding supply 20 having a drooping characteristic and starts a feed motor 47. When the electrode 26 contacts the work 22, a condenser 52 discharges through a solenoid 200 which flexes the guide tube 34 from a path 34<SP>11</SP> to a path 34<SP>1</SP> and thus retracts the electrode to strike the arc. During welding a marginal relay 100 is released to provide a holding circuit for the solenoid 200, but operates to release 200 should the arc be extinguished. The above apparatus may form part of a vertical welding machine having melt retaining pads pressed against the work and a contact tube at the arc end of the guide tube and oscillatable or adjustable transversely of the weld.

Title: Improvements in or relating to the production of a tube from molten thermo-plastic material
Inventor: HOWARTH HENRY HAROLD
IPC: B29C48/09
Filed: 1959-11-06
Abstract: 895,704. Extruding thermoplastic tubes. METAL BOX CO. Ltd. Sept. 5, 1960 [Nov. 6, 1959], No. 37739/59. Class 87(2). An extruded tube of molten thermoplastic material, e.g. polyethylene, is chilled by directing cooling air towards its external surface and causing oscillation of the air about the axis of the tube. For this purpose an annular element 4 is supported in close relation with an extrusion head 3 by means of a fixed annular support 5 on which are mounted rollers 6. The annular element 4 is hollow and connected by flexible couplings 7 with a source of cooling air, e.g. refrigerated air, an annular jet-forming channel 8 extending from the interior of the element to its inner face at such an inclination as to direct the cooling air towards the extruded tube 1 in the direction of its movement. A reversible electric motor (not shown) drives a pinion which meshes with the gear teeth 9 around the periphery of the annular element 4 and operation of the motor to cause oscillation of the element 4 is controlled by a trip means comprising a cam 12 projecting from the element 4 to effect operation of one or other of two switches 13. The distance between the switches 13 determines the angle of oscillation of the element 4. With good air flow conditions, an oscillation through 30 degrees may be sufficient but, in some circumstances, this may have to be increased to 180 degrees in order to produce optimum results. The optimum results are obtained when the direction of movement is reversed every 15 to 90 seconds.

Title: Improvements in or relating to garden shears
IPC: A01G3/06
Filed: 1929-12-11
Abstract: 339,118. Wade, H., (Alliance Manufacturing Co.). Dec. 11, 1929. Shears.-Garden shears carry a foot 14 which has a rubber sector base 16 engaging the ground and is pivoted at 15 to a long handle 4. A link 12 is pivoted to the foot by a pin 13 and to the horizontal blades 7 by a shouldered pin 9. The blades are pivoted by pins 8 on spring arms 5 on the handle 4, which arms, in conjunction with a spring 11 secured in the blades, maintain the blades in open position. Forward pressure on the handle 4 moves the pivot 15 in advance of the pivot 13 so that, although the blades move forward in space, the pin 9 is retarded relatively to the pins 8 and the blades are closed. The shears are then lifted slightly and moved forward, during which action the blades return to open position. An arm seoured to the foot limits its rocking movement by engaging the handle.
