Title: Improvements in and relating to Wireless Signalling Systems.
IPC: H01Q1/52
Filed: 1918-01-19
Abstract: 130,090. British Thomson - Houstor Co., (General Electric Co.). Jan. 19, 1918. Wireless signalling.-In an arrangement for duplex wireless signalling of the kind describec in Specification 127,335, in which separate trans mitting and receiving aerials are employed, the effect of the emitted waves on the adjacent receiv ing-aerial is neutralized by connecting the trans mitting aerial to the receiving-circuits by an arrangement of condensers or by electromagnetic coupling or both. The electromagnetic coupling may act on a secondary receiving-circuit. In the form shown in Fig. 2, the receiving-coil 11 is con nected on the one hand to the receiving-aerial 4 and on the other hand through a condenser 31 to earth and through a condenser 33 to the transmitting-aerial 1. In this way, the effect of the radiation from the aerial 1 on the aerial 4 is neutralized, as in Specification 127,335. The number of turns in the coil 11 is varied by a switch 37, both switch and coil being enclosed in a metallic shield 36. The shield may comprise a wooden box, Fig. 4, lined with sheet metal, the lining being split into two parts by slots parallel with the axis of the coil 11. A coil 38 in an intermediate circuit surrounds the shield 36 and is connected to a coil 39 inductively related to a coil 12 in the grid circuit of a valve amplifier and detector 13. The receiving-apparatus is protected from the electrostatic influence of the coil 11 by the shield 36. The electromagnetic coupling of the transmitting aerial 1 to the receiving circuit is effected by a coil 40 connected to a coil 41 inductively related to the secondary receiving- coil 12. The Specification also describes the arrangement of electromagnetic coupling illustrated in Fig. 1 of Specification 127,335.

Title: Improvements in and relating to test equipment for high voltage transmission lines
IPC: G01R19/145
Filed: 1945-01-16
Abstract: 595,144. Electrification detectors. GENERAL ELECTRIC CO., Ltd., and MITCHELL, J. Jan. 16, 1945, No. 1291. [Class 37] Equipment for testing whether a high voltage line is live, comprises a detector head mounted on a long insulated pole and arranged to apply voltage to an electric discharge indicating lamp. As shown in Fig. 1, a hook 1 for engagement with a high voltage line is connected through an air gap 2 to one electrode of a discharge lamp 3 and to a terminal plug 4. The other electrode of the lamp 3 is connected to a conducting member 5 and a second terminal plug 6. The parts to the right of the dotted line constitute a checking device comprising a socket 7 engaging the plug 4 and two sockets 8, 9 engaging the plug 6. The sockets 7,. 8, 9 are connected to a transformer 10, battery 11, and vibrator 21. When in use the test equipment is supported on a long insulating pole and the plugs 4, 6 are not connected. Discharge passes from the line across the air gap 2, discharge lamp 3, and the capacity of the member 5 to earth and the lamp glows. The detector head is tested by detaching from the pole and plugging in to the checking device, thereby connecting the sockets 8, 9 together and closing the vibrator circuit. Relatively high voltages are thereby generated, stepped up in the transformer 10, and applied to the electrodes of the lamp 3. The hook 1 is fixed to an insulating block 13, Fig. 2, to which is fixed a metal hood 14 which directs the light from the lamp downwards and forms a part of the conducting member 5. The hood is fixed to a metal tube 15 which fits on to the upper end of an insulating pole 18 and is held by a catch 16 operated by a press button 17 so that the plugs 4, 6 are enclosed. The checking device, Fig. 3, is enclosed in a metal tube 19 having at its upper end a screwed socket to receive a plug 28 at the lower end of the pole 18. The battery 11 consists of two cells held in position by a spring 20. The transformer 10, vibrator 21, and sockets 7, 8 are arranged in the lower end of the tube 19, on which is mounted a rotatable sleeve 25 which normally covers the sockets 7, 8 and a hole 24 which permits adjustment of the vibrator. Alternatively the detector head and checking device may be combined to form a single unit which is fitted to the top of the pole, a switch being provided for connecting the lamp at will to the checking device.

Abstract: 1,218,034. Tilting mechanisms for converters. DEMAG A.G. 9 Jan., 1968 [27 May, 1967], No. 1292/68. Heading F4B. A common drive system 4, including one or more drive motors 17 is located between adjacent converters 1, 2, so that the or each motor may be optionally used for tilting either or both of the converters. The electric motors 17 may be connected to reduction gear assemblies 13, 14 and 15, 16, which respectively drive planetary gear units 11 and 12 mounted on the trunnions 5 and 6 of the respective converters 1 and 2, through flexible clutch couplings 23 capable of accommodating relative displacement of the motors and the gear assemblies due to sagging of the trunnions 5 or 6. Preferably two driving motors are connectable to each reduction gear assembly (Fig. 2, not shown). Torque resistant fixing means 19, 21 and 22 prevent rotation of the housings of the reduction gear assemblies and the planetary gear units respectively. Stop means (not shown) may be provided to retain the converters in their tilted positions. All of the gear assemblies may be located below the level of the converter platform 3.

A pad for a sole laying press includes a deformable bag 29 filled to a suitable level with pellets 43 such that pressure of the bag 29 on a shoe can deform the bag 29 to define a shape complementary to the shoe bottom and displace the pellets 43 in various directions into positions in which the pellets 43 form a compact mass. Suitable pellets are made of high density polyethylene, nylon or glass. The bag 29 has an air vent 41 to allow air to escape and which may be connected to source of vacuum after the bag 29 has assumed the correct shape to hold this shape while shoes of the same size, style, etc. are operated on. In a first embodiment (Fig. 1) a pad for use with low or medium height heels is shown. The bag has its forepart portion supported by a plate 9 and its rearward portion supported by a plate 11, the plates 9, 11 being mounted on shafts 13, 19 which can be rotated by handles to adjust the shape of the pad to suit various styles of shoe. The machine also includes a heel support 55 which can be moved into engagement with the heel along a slide 57 and is locked in position by a ratchet 65 and pawl 63.

Abstract: 130,365. L'Air Liquide Soc. Anon. pour l'Etude et l'Exploitation des ProcÚdÚs G. Claude. Aug. 25, 1917, [Convention date]. Ammonium chloride; sodium bicarbonate. - Ammonium chloride is prepared by treating synthetic ammonia according to the ammonia-soda process, the carbon dioxide for the process being obtained, in part from the water gas used in making the hydrogen for the synthesis of the ammonia, and in part by calcining the sodium bicarbonate to produce sodium carbonate. To obta.in the ammonium chloride free from bicarbonate so that it may be used as a manure, it is purified by fractional crystallization, or the solution, after separation of the precipitated sodium bicarbonate, is neut a ized by acid before the ammonium' chloride is crystallized out. The manufacture of the water gas may be so conducted that the gas consists of hydrogen, carbon monoxide, and carbon dioxide, the carbon monoxide being in such proportion that it is sufficient, in conjunction with the waste hydrogen from the ammonia synthesis, to supply the power necessary for the process. The hydrogen may be obtained from the water gas by cooling and compressing the gas to liquify the carbon dioxide and then treating the cooled and compressed gas with a solvent as described in Specification 130,358, to extract the carbon monoxide. Alternatively, a water gas consisting of carbon monoxide and hydrogen may be produced and then catalyzed with steam to produce carbon dioxide and hydrogen.
