Title: Improvements in joints for electric cables
IPC: H02G15/196
Filed: 1944-11-11
Abstract: 583,642. Cable joints. CALLENDER'S CABLE & CONSTRUCTION CO., Ltd., and BRAZIER, L. G. Nov. 11, 1944, No. 22248. [Class 38 (i)] A joint between two lengths A, B, of cable comprising a conductor 5 with a helically - lapped strip dielectric 4, is insulated by building up the dielectric in layers, wholly or partly of strips each integral with, and a continuation of, a strip forming part of the dielectric surrounding one or other of the lengths. The outer covering 1, sheath 2, and screen 3 are cut back to expose a length of dielectric 4. The strips of one cable length B are individually unwrapped until the innermost strip, B1, is unwound to a point 6, a greater distance than the overlap. As each strip, Bn, Bn-1 ... , is unwrapped it is secured on a hook 8 and immersed in a tank 7 of hot impregnating compound extending across the exposed lengths A, B. When both dielectric lengths have been exposed the conductors are cut so that they butt together and are joined in a known manner, e.g., by a flush ferrule 11. The dielectric is restored by replacing the strips, A1, B1; A2, B2 ; ... in layers so that part of each layer is formed by a strip from A and part by a strip from B. The innermost strip B1 is rewrapped over for nearly the full length of the exposed conductor, to a point beyond which the strip B1 is to butt on the strip A1 At the location J1 of the butt joint a length of weighted piano wire is hung over the strip B1, which is then torn along the arc of the wire. The wire is removed and the strip A1 is rewrapped beyond J1. The wire is placed over the strip A1 in alignment with the torn edge of strip B1 and the strip A1 torn along the arc. The second layer is restored by rewrapping strip A2 over the strips A1, B1, and tearing it beyond the ferrule, and wrapping strip B2 to make a butt joint, as described, with the torn edge of strip A2 at a point J2. As the remaining layers are restored care is taken to keep the successive joints out of register, Fig. 6. Additional dielectric in the form of a convolute sheet wrapping or tube may be applied over the joint. The surface of the dielectric is made conductive so that the screens 3 are electrically continuous, and the whole joint is enclosed in an impervious sleeve joined to the sheath ends 2, Fig. 6. Alternatively, only the most highly-stressed layers are built up from the original strips and the remaining layers by lapping on fresh strip or sheet over the butt-jointed layers, Fig. 7 (not shown). The method may also be applied to cables with thermoplastic strip dielectric, the joints between the strips being welded. The method is also applicable to multicore cables.

Abstract: 517,002. Paraffin wax. STUDIEN-UND VERWERTUNGS-GES. July 27, 1938, No. 22394. Convention date, July 30, 1937. [Class 2 (iii)] Paraffin wax is produced by the catalytic treatment of carbon monoxide and hydrogen with a cobalt or cobalt-containing catalyst at below 250‹C. and at least 2 atmospheres pressure, the gas throughput being the same by weight as that which gives the maximum production of hydrocarbons containing at least 2 carbon atoms at atmospheric pressure. Suitable pressures are 2-50 atmospheres. The pressure may be equal to that of saturated steam at the temperature chosen, as. then with external water-cooling the pressures on both sides of the reaction chambers are equal. In an example, the gas mixture is treated with a cobalt-thoriakieselguhr catalyst at 190‹C. and at 10 and 15 atmospheres pressure. The catalyst preferably rests on a permeable support such as a sieve so that the paraffin wax trickles away from the catalyst.

Title: Improvements in and relating to electric switches of the explosion-pot type
IPC: H01H33/75
Filed: 1932-08-10
Abstract: 384,952. High-tension switches. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A. -(Assignees of Allgemeine Elektricitats- Ges.; 2, Friedrich Karl-Ufer, Berlin.) Aug. 10, 1932, No. 22426. Convention date, Aug. 10, 1931. [Class 38 (v).] In switches of the explosion-chamber type, loss of the switching liquid, such as water, is avoided by enclosing the pot 1 in a second chamber 4 of restricted cross section, so that only a small volume of liquid is set in motion, and enclosing the second chamber in a third chamber 7 which serves as a storage vessel to receive the ejected liquid; and restore it to the explosion chamber. The liquid in the second chamber is at a level only slightly above the opening of the pot ; a height equal to the diameter of the opening is referred to. The liquid in the third chamber is at the same height and the two levels are maintained the same by a one-way valve 9 in the wall of the second chamber which admits liquid from the third to the second chamber. The water ejected at break passes through the orifices 5 and is deflected by the baffles 6, 11 into the third chamber from which it flows to the second chamber and to the explosion pot. When assembling several units, as described, to constitute a polyphase switch the external chamber may have a triangular or oval form.

Title: Improvements in or relating to friction clutches for the transmission of power
IPC: F16D13/04
Filed: 1928-08-03
Abstract: 321,637. Gillett, E. H. J. C. Aug. 3, 1928. Controlling different functions by same lever; guarding against wrong movements and the like; relay or power apparatus.-Comprises a transmission system in which a clutch is operatively connected to the engine accelerator pedal or other speed-controlling member and to a servomechanism deriving energy from the engine in such a manner that movement of the pedal to accelerate the engine engages the clutch lightly which thereupon brings the servo-mechanism into .action to effect and maintain tight engagement of the said clutch until the driven shaft at any time overruns the driving shaft, whereupon the .clutch is automatically disengaged. The invention is shown applied to a clutch mounted at the rear of the change-speed gear. A clutch disc 2 is slidably-keyed on the driving shaft 1 and is adapted to be engaged by friction annuli 5, 6 carried by a casing 4 freely mounted on the driven shaft 17. The clutch is normally disengaged by springs 10 and is engaged by means of .a sliding plate 12 which is freely mounted on the driven shaft and is operated by the accelerator pedal 28 through a cam 25, arm 24, a sliding collar 21 and pins 18. When the pedal is depressed, the clutch is lightly engaged so that the disc 2 drives the casing 4 and plate 12. Inclined dog teeth 14 on the plate 12 then engage and drive similar teeth 15 on a collar 16 fixed to the shaft 17, so that (1) the drive is transmitted through the dogs to the shaft 17 and (2) the resistance of the shaft 17 exerts a wedging action on the inclined teeth and slides the plate 12 to effect tighter engagement of the clutch until the drive is fully taken up. When the accelerator pedal is released, the plate 12 is brought back to its original position by springs 29 so that the clutch is disengaged. A dash-pot 31 connected to the arm 24 comes into action after the clutch is first engaged and ensures smooth engagement. The dogs 14, 15 are inclined on both faces so that the clutch acts similarly for both directions of rotation. In order to prevent engagement of the clutch in the reverse direction except when the driven shaft is stationary, a pawl (not shown) is pivoted to the plate 12 and is adapted to engage a, notch in the collar 16. Normally, the pawl is held out of action by means of a spring but when the plate 12 rotates at more than a very low speed, a weighted end of the pawl moves under centrifugal force and causes tue pawl to engage the collar 16, so that the inclined dogs 14, 15 are prevented from coming into contact and the drive is not transmitted. According to the Provisional Specification, the brake lever or pedal may be connected to the clutch so that when the brake is applied, the clutch is disengaged. Specification 310,783, [Class 80 (ii), Gearing, Variable-speed &c.], is referred to in the Provisional Specification.

Title: Ammunition supply apparatus for gun turrets
IPC: F41A9/04
Filed: 1924-10-01
Abstract: 242,402. Beardmore & Co., Ltd., W., and Webster, T. H. Oct. 1, 1924. Loading-appliances. --Relates to apparatus for transferring ammunition from a shell-room or magazine to the hoist openings or hatches in the turret-trunk of the kind in which the ammunition is conveyed from a stationary platform 11, see plan Fig. 2, to the hatch 22 by trollies 6 which travel on tracks 1, 2 surrounding the trunk 3, means being provided for arresting the trollies at the platform or hatch and locking them temporarily in position. According to the invention, a continuouslydriven propelling member follows the contour of the track and the trollies are automatically coupled to and uncoupled from this member on departure from or arrival at the platform or hatch. In the arrangement shown in Fig. 2, the upstanding projectiles X received on the trollies 6 from the platform 11 are propelled round the track by a toothed ring 4 continuously rotated by a shaft 10. The coupling and arresting gear beneath each trolly is shown in Fig. 4 and comprises a lever 15 fulcrumed at 16 and having one arm fitted with a spring catch 13 normally engaging teeth 12 on the ring 4 the other arm engaging a cam groove 18 in a lever 19 which is coupled by cam surfaces 26, 27 and link 28 to a second lever 25 which bears against a spring buffer 33. Carried by the turret near the hatch is a hinged stop 20 which engages the lever 19 to release the catch 13 and stop the trolly which is then held against the compression of the buffer 33 by a catch 23 on the stop 20 which engages teeth 24 on the trolly. On releasing the stop 20, the spring 33 reacts to move the levers 25, 19 and cause the re-engagement of the catch 13 with the propelling ring 4. A similar stop 29 is provided at the platform 11. If two trollies collide, a plunger 35 is pushed against the lever 19 to stop the rearmost trolly. In a modification shown in plan in Figs. 8 and 10, in which the shell-room hatch 11 is some distance away from the turret-trunk, the track follows a circuitous path and the propelling means is in the form of an endless steel band 36 guided by pulleys 37. The trollies are provided with spring-pressed jaws 40, 41 which grip the band when driving, and are automatically opened to arrest the trollies by a cam 45 actuated by a lever 47 contacting with the stop 20 as described with reference to Fig. 4. The trollies may be locked to the ring or band by electromagnets mounted on the trollies.

[Also in Group XXIX] A pump for spraying insecticides &c. comprises a housing 13 having a partition 36 to which is secured a barrel 12 of porcelain or ceramic ware. The piston 18 is actuated by an eccentric operating in a slottted yoke 20 on the piston rod 19 which is extended to enter a guide 23. The eccentric is supported by bearings in each side of the casing 15 and the driving shaft protrudes from the casing so that it can be driven from a power take-off of a tractor; an Oldham coupling 55 is arranged between the driving shaft and the eccentric. The pump is double-acting and a valve box 26 is arranged on the side of the housing 13; a relief valve con nects the delivery and suction sides of the valve box. The pump delivery is connected through a stop valve 63 to the inlet 57 of a control valve 64 comprising a cylindrical valve member having a helical slot 69 co-operating with a pin 70 so that rotation of the handle 65 causes axial movement of the valve member to lift it. from its seat adjacent the inlet 57. When the valve is closed, a flow is maintained through the nozzle 73 into the bore 67 to cause an injector effect and draw liquid from the spraying boom through opening 72 and port 74 and return it through ports 75 to the opening 71 connected to the liquid storage tank; dripping at the boom is thus prevented. As the valve member is moved off its seat, a variable by-pass through ports 74 and 75 is maintained thus controlling the pressure to the spraying boom until the ports 75 are closed and full pressure is established. A relief valve may be associated with the control valve 64.

[Class 39 (i)] The deflecting plates and other electrodes of Braun tubes are " outgassed " in such a way that residual magnetism is avoided. In one method, the electrodes are subjected to electron bombardment by controlling the cathode ray. In other methods, the electrodes are subjected to an eddy-current field. A D.C. component in the " outgassing " coil is avoided ; a choke may be connected in parallel to the coil. The coil may be supplied from a " tube generator " or other source of undamped oscillations or from an impulse spark generator so connected that successive spark discharges act in opposite manner on the coil. An impulse spark generator with rapid sequence of sparks, for example 10,000 per second, may be used. The eddy-current field may increase and fade away slowly and the " transmitter " is screened off or at a distance from the coil.
