Abstract: 949,850. Making toothed members. GENERAL ELECTRIC CO. Nov. 16, 1960 [Nov. 25, 1959], No. 39351/60. Headings B3A and B3R. [Also in Division F2]  A toothed torque-transmitting member such as a gear or a toothed coupling member, comprises a body2 of readily weldable ductile metal to which is applied by fusion welding an overlay 3, 4 of high strength wear resistant metal into which the teeth 5, 6 are formed. A cylinder 2 is rolled from low carbon steel plate and the ends joined by butt welding. Overlays 3, 4 of medium carbon steel are then applied by a D.C. straight polarity submerged arc welding process using two filler wires of higher carbon steel than the finished overlay to allow for loss of carbon during the fusion. The cylinder 2 is preferably pre-heated to 150‹ C. and is rotated during the weld application which proceeds in a helical path with minimum penetration into the cylinder metal. Alternatively, the weld may be applied in longitudinal runs using a reciprocating welding head. An inert gas shielded process may be used. Opposed helical teeth 5, 6 are then machined and subsequently heat treated. Other embodiments are described of coupling members with internal or external teeth, Figs. 3, 4 (not shown). An example is given of the welding voltage, current and speed.

Abstract: 1,131,986. Hand punches. HAYDENNILOS Ltd. 1 Sept., 1967 [5 Sept., 1966], No. 39506/66. Heading B4W. A hand-tool for punching holes in conveyer belts comprises an anvil 2 carried by an elongated handle 4, a guide 7 for the punch 11 also carried by the handle, a pivot on the side of the guide remote from the handle 4 for an elongated hand lever 22 extending generally parallel to the handle 4 and also pivotally connected at 23 to a head 15 supporting the punch 11, the punch being rotatable about its own axis with respect to the head, and means being provided between the guide 7 and the punch 11 for effecting rotation of the punch 11 automatically upon its thrust towards the anvil 2 by movement of the hand lever 22 towards the handle 4. As shown, closure of the hand lever 22 lowers the head 15 and hence, preferably by means of a thrust bearing, the spindle 10 and the hollow punch 11 which is guided through a boss 8 mounted in the upper arm of support 3, and through a hard metal insert 5 in the anvil 2. A pin 13 extends through the wall of the boss 8 and engages a helical groove 14 in the spindle 10 so that as the spindle 10 and punch 11 move longitudinally they also rotate. When the hand lever 22 is retracted a pair of pins 16 engaging loosely a peripheral slot in the spindle 10 cause the head 15 to retract the spindle 10 and punch 11. The punch 11 and anvil insert 5 are detachable to allow different sized holes to be punched. In operation the end of a belt is buffed against the end of the U-member 3 and a hole punched. The belt is then moved along and a peg (26), Fig. 3 (not shown), inserted through the two arms of the U-member 3 and through the hole just punched, thus ensuring the correct spacing for the next hole to be punched. A bar 28 is passed through a hole 29 to ensure that the holes punched are parallel to the belt end. The anvil 2 may be secured in a vice.

Abstract: 1,202,595. Anti-snaking device for vehicle couplings. P. HAHN. 30 Aug., 1967 [30 Aug., 1966], No. 39692/67.. Heading B7T. An anti-snaking device for a ball-and-socket coupling comprises a shank 2 of ball 1 rotatably mounted in a U-shaped support 5, the shank having rigidly connected with it by means of pin 12 a U-section member 10 with flanges 11, the flanges having pivotally connected between them the rod ends 16 of resilient piston and cylinder shock absorbers 18, which shock absorbers tend to resist rotation of ball shank 2 caused by snaking between the towing and towed vehicles. The shank 2 is slidably connected with a guide member 25 of the towed vehicle by a vertically resilient member 23 comprising spring blade 24 and a forwardly projecting member 27 having a portion 28 in a vertical plane which passes through a slot in the shank. Retaining pins 32, 33 prevent excess longitudinal movement of member 23. The cylinders of the shock absorbers are pivoted at 20 between parallel plates 21 extending from either side of shank 2. In a second embodiment of the invention, Fig. 7, the ball shank 102 is rotatable in a support 105. In the normal position of the shank a ball 35 is retained in a slot 34 therein, the ball also being in contact with a resilient pad 38. On rotation of the shank caused by snaking cam faces 40 thereon press the ball into the pad 38, thereby resisting the rotation. The pad 38 is mounted in a hollow nut 37 threaded into support 105. Rotation of the ball and its shank can be caused during snaking by allowing a pin 41 rigid with the socket to engage a vertical slot 42 in the ball.

Patent GB-400929-A (GB)
Abstract: 400,929. Cables. HENLEY'S TELEGRAPH WORKS CO., Ltd., W. T., 11, Holborn Viaduct, London, and DUNSHEATH, P., Hesket, Church Avenue, Sidcup, Kent. April 27, 1932, No. 12101. [Class 36.] In a cable the insulation of which is impregnated with oil &c. exposed to the pressure of gas enclosed between the insulation and the cable sheath the gas space is electrically screened and is divided longitudinally into a number of separate spaces. For this purpose a helical strip 5 may be interposed between the insulation 4 and the sheath 6 and the spaces between the lower parts of the coils filled with a composi. tion 7 which is introduced in liquid form and sets gas tight. Strings 8 may be wrapped in the insulation to assist in retaining the composition in place. The surface of the insulation is covered with metallized paper, perforated or helically wound with spaces between the turns to give the gas access to the insulation, and the surface of the strip 5 is also metallized. To prevent the gas escaping from one compartment to the next along the core this is built up of sector-shaped strands, as shown in Fig. 22, and covered with oiled silk 2 or the like, or the space between the wires may be filled with soft metal &c. The strip 5 may be wound at different pitches, some successive turns 9, Fig. 4, being in contact to separate the gas chambers. The portions of strip between such sets of turns in contact may be removed. To ensure a gas-tight joint between the strip 5 and the sheath 6 a metal tape 12 may be wound outside the sheath pressing it down onto the strip Fig. 6. The gas may be compressed by forcing the sheath 6 inwards between the turns of the strip 5 by means of a metal tape 13 wound on it, Fig. 7, or by forcing the impregnating liquid into the chambers through the insulation. Alternatively the gas may be introduced in a compressed, adsorbed, or solid form and afterwards liberated. For this purpose the gas may be contained in a flattened helical tube 23, Fig. 9, arranged between the turns of the strip 6. The tube 23 may be of fusible metal and melted to liberate the gas by means of resistance wires 26, 27 or it may be of steel with fusible plugs melted by heating by induction. It is divided into sections by plugs which may also be employed to separate the gas chambers. Alternatively it may be made of fabric and the edges sealed by a viscous compound; on heating the gas is liberated and the compound 7 enters the tube and seals it. Or the cable may be sealed at a low temperature and the pressure produced by the expansion of the enclosed gas or its escape from a solution. Adsorbed or solid gas may be introduced, spread on, or folded into fabric strips and covered with or sealed by a material such as wax which will allow the gas to escape after a time. The application of the invention to a three-core cable is also described,

Title: Sublimation pump and method of regulating it
IPC: H01J41/16
Filed: 1970-08-25
Abstract: 1,254,659. Ion pumps. HULL CORP. 25 Aug., 1970 [6 March, 1969], No. 40855/70. Heading H1D. [Also in Division G3] In a sublimation pump, the cooled gasadsorbing metal surface of the pump cylinder 10 and a heated metal filament 54 are made the anode and cathode respectively of a spacecharged limited current diode which is included in a bridge circuit for detection of its currentvoltage characteristics. Potential differences across the bridge circuit resulting from changes in the extent of absorption of gas and deposition of vaporizable metal on the anode are amplified and used to control the heating of the vaporizable metal 24 in the cylinder, which has a conduit 16 adapted for connection to a vessel to be evacuated. When the adsorption of an electronegative gas layer covers a predetermined area of the anode, the reduction in current of the space charged limited current diode produces a potential difference across bridge-terminals 72, 90, which provides a signal of sufficient magnitude, when amplified by differential amplifier 92, to fire silicon controlled rectifiers 44, 46. Current is thus supplied from power source 34 to the rod 24. For operation with an electropositive gas layer, the switches 98, 100, are changed-over and amplifier 102 becomes effective to act as a reverser. The pumping speed is increased or decreased by adjusting the value of the reference resistor 76. To reduce the pumping speed, the resistance is increased so that the output of the amplifier is insufficient to fire the silicon controlled rectifiers. When sufficient gas particles have been adsorbed on the anode surface, the current through the resistor 76 equals the total diode current. Further adsorption of gas causes firing of the rectifiers and consequent deposition of metal on the anode. Gases exemplified are oxygen, nitrogen, hydrogen, ammonia, carbon monoxide, sulfurdioxide, tetracyanoethylene, and water vapour and the absorbing surface may be cooled by water or liquid nitrogen 22 for example. Rod 24 may be Ti, Mo, W, Ta, Zr, Cr, or Ba and evaporation by an electron beam source or the material may be a filament rod.
