Title: Improvements in electric time switches
IPC: G04C23/24
Filed: 1933-06-15
Abstract: 409,917. Time switches. PAULITSCHEK, E., 31, Weisestrasse, Neuk÷lln, Berlin. June 15, 1933, No. 17087. Convention date, June 25, 1932. [Class 38 (v).] A time switch particularly for switching a radio set on and off at given times, comprises a double disc b, 11, driven by clockwork to rotate once in twenty-four hours. A series of pins c having enlarged central portions 13 are frictionally mounted in holes situated at frequent regular intervals round the edge of the disc, in such manner that when the pins are pushed inwards the enlarged central portions 13 just engage the tip of an escapement lever d, normally held by a spring against a stop r. Bearing against the upper corner 9 of the lever d is a pin f on a wheel e connected by gearing g, h to a clock spring l. Mounted on the same shaft as the gear h is an insulating lozengeshaped cam adapted on rotation to engage a contact spring k to open or close the circuit to the radio set. In operation, the pins c corresponding to the desired times of switching on and switching off are pushed inwards by means of a spring plunger p on a rotatable arm o. When the switching on time arrives the enlarged portion 13 of the pin c engages the tip of the lever d allowing the pin f to fall on to the lower corner 10 of the lever d until the latter is released by the pin c, thus releasing the pin f. The wheel e makes a complete revolution due to the clock spring l and the pin f again comes to rest against the upper corner 9 of the lever d. The cam has then made a quarter revolution and the circuit is completed. While the wheel e was making a revolution, a spiral cam n on the spindle engaged a lever m to depress its bent-round end 3 to push the pin c outwards into its non-operative position. When the next operative pin c comes round it engages the lever d as before to cause another complete revolution of the wheel e and a quarter revolution of the cam to open the circuit.

Title: Apparatus for manufacturing electric power cables
Inventor: WATANABE ITARU
IPC: H01B13/00
Filed: 1963-05-01
Abstract: 1,039,760. Making oil-filled cables. FURUKAWA DENKI KOGYO KABUSHIKI KAISHA. May 1, 1963, No. 17116/63. Heading H1A. In a process for manufacturing power cables in which the cable is dried and/or impregnated in a tank and then passes through a communication tube to a sheathing process, the tank is sealed from the tube by a packing plate which is deformed when the cable is to enter the tube and precedes the cable through the extruder. In the arrangement shown (Fig. 3), a vacuum inside the drying tank 1 causes a packing plate 7 attached to the cable to bear against the external face of one of a pair of flanges used to couple the tank to the tube 1. Insulating oil then enters the casing and plate 7 moves up against the right-hand flange 10 so as to seal in the oil. Next the towing wire is led out through the extruder and sealed into a sheath and the tube 1 is evacuated and filled with oil. When the extruder is operated the packing plate is deformed to allow the end of the cable to enter the tube and the deformed plate passes through the press and is sheathed with the cable. A more readily deformable plate is described and arrangements for controlling the pressures in channels in the flange faces so as to improve the seal made by the plate. In a still further embodiment, a solenoid is used to urge a magnetic member to force a plug into the extruder so as to draw the cable through behind it.

Abstract: 393,421. Valve circuits for wireless reception. TELEFUNKEN GES. FR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. June 17, 1932, No. 17221. Convention date, June 17, 1931. Addition to 393,415. [Class 40 (v).] The method of obtaining automatic gain control by employing a rectifier, the output current of which is a logarithmic function-of the input voltage, as described in the parent Specification, is modified by associating a rectifier having ordinary characteristics with a subsequent amplifier stage in such manner that the combined rectifier and amplifier exhibit the required characteristic, the amplifier output being a logarithmic function of the rectifier input. The leaky grid detecter 1 has its anode circuit directly coupled to the grid of the amplifier 7 through a resistance R which is high compared with the grid-cathode resistance of the amplifier (e.g. 100 megohms), the anode resistance 4 of the rectifier being shunted by the high-frequency byepass condenser 5. The voltage tapping point F is adjusted until there is no direct current potential difference between points F and G with no signal. The above arrangement gives the required relation with a linear-characteristic rectifier ; if the rectifier characteristic is quadratic, a plurality of amplifier valves having different characteristic may be used in combination.

IPC: B21B3/00
Filed: 1953-06-24
Abstract: 740,408. Making plates and sheets. MALLORY-SHARON TITANIUM CORPORATION. June 24, 1953, No. 17483/53. Classes 83 (2) and 83 (4). Rolling; working at specified temperatures.- In a method of hot rolling titanium to thin gauge sheets, rectangular ingots are rolled to sheets of intermediate gauge which are then sandwiched between sheets of metal such as steel having a lower heat conductivity than titanium to retain the heat and protect the titanium surfaces against oxidation during rolling to the final thickness. In examples round ingots at a temperature of 1700‹ to 1850‹ F. are described and flattened into rectangular slabs in successive forging stages. The slabs are then reduced by rolling in a number of stages after heating and reheating in continuous furnaces under a reducing atmosphere initially to temperatures of 1520‹ to 1580‹ F. and at later stages to a temperature of 1350‹ F. followed in some cases by doubling and redoubling of the sheet. In one example four sheet thicknesses resulting from doubling and redoubling are sandwiched between two sheets of steel, heated to 1350‹ F. rolled in two stages, hot doubled, reheated and given final rolling passes until the sheets are reduced to a thickness of 0.013-0.014 inches. The resultant eight-titanium sheets are then separated. The finished sheets after annealing and pickling may be cold-rolled to as much as 50 per cent reduction.
