Title: Improvements in or relating to electric cables
IPC: H01B11/12
Filed: 1928-05-11
Abstract: 290,257. Weitverkehrskabel Ges. May 11, 1927, [Convention date]. Induction, preventing and minimizing.-To 'equalize the differential capacities of cables in telephone circuits an electric current is passed, after the line has been laid, through the cable core or an auxiliary conductor arranged between the cores or in their insulatious, for instance. within a coil of paper having three strands, the heat magnetic, electrostatic or electrolytic effects of the current being used to modify the capacity throughout the whole length of cable. In using the thermionic heat of the current, a temperature above the normal drying temperature of the cable, and below that which might damage the paper insulation, is used, a temperature of 120‹ C. being preferred. When the metal is used as a capacity equalizer, the conductor, before insulation may be thinly coated with metal melting at 120‹ C., and after the cable is finished, the current is passed to soften or melt the metal so that it partly saturates a coil of paper surrounding the condenser, or, the conductor may be coated with a metal sublimating at the equalizing temperature, the metal being partly precipitated, when heated, on the insulation; or, a salt, e.g. of ammonia may be distribuated on the conductor or in the insulator so as to be decomposed into a metal and a gas, the escaping gas being removed by air ventilation. Instead of a metal layer on the main conductor, the main conductor itself may be used, or an electrical effect between the main, and an auxiliary, conductor may atomize or burn metal, carbonize the insulating material, or melt other dielectric substances.

Title: Apparatus and process for continuously making baked and/or graphitized carbon bodies,or for applying electrothermal energy to conductive compositions
IPC: C04B35/532
Filed: 1964-04-03
Abstract: <PICT:1047137/C1/1> Baked or graphitized carbon bodies are produced by continuously forcing a carbonaceous mass through a zone in which it forms a resistance element in a closed electrical circuit and is heated thereby, and exerting a restraining force on the moving mass. The mass 6 which may be graphite flour, carbon black, calcined petroleum, resistor coke and/or anthracite, with or without 15-45 parts of a binder, e.g. pitch or a synthetic resin, per 100 parts of the mass, and which may be loose or preformed, is periodically fed into a reducing die 3, 4 and heated to 20-350 DEG  C. by coils 5 or by hot gases. The extrusion die may alternatively have an expanding or constant cross-section, e.g. irregular, circular, or rectangular, or may change from one to the other, and tubes may be formed using a cylindrical mandrel, which may form part of the circuit.  The mass is forced at 0.25-3 inches/minute by piston 1 into the baking zone where it is heated to 125-1300 DEG  C. by passing an A.C. or D.C. current of 600-2000 amps. from transformer 13 through contacts 14 and 15. Resisting force may be exerted peripherally by frictional drag 16, or by the contacts, or axially e.g. by an hydraulic piston.  The forward pressure may be 100-6000 p.s.i. and the back pressure 10-4000 p.s.i. The process may be started by heating up a rod of graphite ahead of the mass and extending between the two contacts.  In the optional graphitization zone, the mass is surrounded by tubes 19a and 19b of graphite and steel respectively, containing e.g. carbon black 19, and is heated to 800-2900 DEG  C. by passing current from transformer 17 through contacts 15 and 18.  Finally the mass is cooled from 2900-300 DEG  C. in a zone comprising graphite, steel, or copper 21 surrounded by water-cooled copper coils 50.  It may be cut to length at 25-400 DEG  C.  Contact 14 may be of copper or steel, and contacts 15 and 18 of carbon, copper or graphite. Nitrogen is introduced through inlets 20, 20a and 20b, and volatiles escape at 12.  In another embodiment, the downstream contacts are omitted and the current passed radially through the mass; various electrical arrangements are illustrated.
Patent GB-829331-A (GB)
Title: Pawl and ratchet intermittent driving mechanism
IPC: G04B11/04
Filed: 1957-05-02
Abstract: 829,331. Ratchet gearing. MALLORY & CO. Inc., P.R. May 2, 1957 [May 8, 1956], No. 14006/57. Class 80 (3). In ratchet gearing, particularly for a timer switch in a washing- machine or the like, a driving pawl 27 carried by an oscillating arm 16 engages a ratchet-wheel 7, and a spring-loaded pivoted arm 32 is shaped to co-operate with the pawl 27 and wedge it against the wheel at the end of each stroke to prevent overrun. Back running is prevented by a pawl 52. The arm 15 is pivoted at 25 and is held by a spring 18 against a threelobe cam 14 geared to a constant-speed drive. The cam-engaging portion of the arm 16 is shaped to allow the spring 18 to effect a rapid wheel-turning movement of the arm as the end of each cam lobe is reached. The pawl 27 is composed of a tooth-engaging member 37 on a main section which has a finger 30 extending into a seat in the pivoted arm 32. The arm 32 is urged by a spring 50 towards the wheel 7 and thus continuously holds the member 37 against the ratchet teeth. Each driving stroke is terminated abruptly by the finger 30 abutting the seat in the arm 32 and thus wedging the member 37 against the wheel 7, since the seat is off-centre with respect to the line joining the pivots of the pawl 27 and arm 32. The cam 14 is shaped so that the arm 16 does not contact it when the finger 30 on the pawl 27 abuts the said seat at the end of a stroke. The ratchetwheel 7 may be coupled to switches by gearing or by cam-actuating posts such as 90. If sufficient force is applied to overcome the springs in the mechanism, the ratchet-wheel 7 may be advanced manually to miss parts of a cycle. The arm 16, pawl 52 and arm 32 are pivoted on a triangular plate 80 which is pivotally adjustable about the axis of the ratchet-wheel to vary the angular relationship between the cam 14 and wheel 7 and is locked in position on a base-plate by a screw 92.

Title: Improvements in or relating to indicating devices
IPC: G01F23/44
Filed: 1945-06-06
Abstract: 602,349. Telemetering. LIQUIDOMETER CORPORATION. June 6, 1945, No. 14221. Convention date, Sept. 29, 1944. [Class 40 (i)] In a system for indicating a quantity, e.g. liquid level, coarse and fine ratiometer indicators are associated with mechanically connected contact arms which move respectively over a single resistor and a number of parallel connected resistors in a resistance transmitter, so that the fine ratiometer gives a vernier indication of a portion of the coarse ratiometer scale. Fig. 3 shows an arrangement in which float 45 moves an arm 31 carrying two wipers 23 and 26, moving over resistance elements 21a and 22a-e respectively, and connected to ratiometers 37 and 38 by lines 39 and 41. Resistance element 21a and wiper 23 are so connected to ratiometer 38 that the position of the resultant field produced by the currents in coils 37a-c and hence the position of pointer 16 carried by magnetized rotor 37e varies in accordance with the position of float 45, and is arranged to give full scale deflection when the extreme float position is reached. Ratiometer 38 is similarly associated with parallel connected elements 22a-e to give a succession of expanded readings as the arm 31 is deflected (e.g. the ratiometer 38 may be calibrated to read " units " while 37 reads " tens "). In a modification, Fig. 7, the ratiometer coils are arranged to give a 360 degrees scale reading by connecting them in star to taps on potentiometers. formed, for example, by resistor 78, and the portion of resistor 75 between the tap 82 and earthed wiper 96. The resistance elements may be non-uniformly wound to give a linear indication of the contents of a tank having a non-uniform cross-section (as in Fig. 5, not shown). The ratiometers may be of the type described in U.S.A. Specification 2,339,021 and may operate concentric pointers. Specification 483,450 also is referred to.

Abstract: 1449674 Welding by fusion CLARKE CHAPMAN Ltd 19 April 1974 [24 March 1973] 14304/73 Heading B3R In internal non-consumable electrode, filler wire, arc welding of a tube or tubular stub to a tube plate or tubular stub extending from (e.g. brazed, friction welded or diffusion bonded to or formed from) a plate, two or more equiangularly spaced non-consumable electrodes are moved together relatively to a workpiece so that each electrode effects a weld or welds along an arcuate path of less than 360 degrees extent but sufficient to overlap the path of its preceding neighbour. In the tubular stub/plate TIG welding shown, a head 20 extending through a stub 14 rotatably carries two diametrically opposed non-consumable electrodes 22. Electrode rotation about an angle slightly more than 180 degrees is effected by drive means (not shown) at the upper end of the head. Welding current is fed to the electrodes through a conductor 24. Shielding gas and cooling water are fed to the vicinity of the electrodes respectively through a conduit 26 and further conduits (not shown) within the head. A head locating clamp 30 engages the stub bore and/or, as shown, a bore 12 of a plate 10. The stub is held in position on the plate by a clamp 48 which comprises a two part body, is secured to the plate by means not shown, and is tightenable on to the stub by a flexible steel band 46 acted on by a screw (42, Fig. 2, not shown). The clamp body also provides an enclosure for inert backing gas fed through a conduit 50. In Fig. 3 (not shown), the head is extended through the plate and clamp located in a tube and/or in the plate. In operation, initially two tack welds may be made, with the electrode stationary, and after checking stub/plate alignment the complete welding effected. The electrodes may be adapted for plasma arc welding and both constant and pulsed welding current may be used. TIG welding preferably includes arc length control. The electrodes are preferably variably disposed at angles within Œ 60 degrees with respect to the plane of the joint. The drive means may produce intermittent electrode movement. Welding current may be varied at starting and finishing, and, if desired, and if a series of overlapping welds is required, as by pulsing during the arcuate movement to effect intermittent welds either with uniform or intermittent movement. Preferably, welding current is controlled in respect of materials welded and weld penetration and profile, by feedback means based on frequency and/or slope of current pulses and current on/off ratios. The stub engaging surface of the plate may be a layer applied by explosion welding, roll cladding or weld deposition. The stub may be a transition piece of material suitable for welding to plates and tubes of different materials.
