Title: Recoverable article with fusible insert
IPC: H02G15/18
Filed: 1963-07-23
Abstract: 1,062,043. Cable joints. RAYCHEM CORPORATION. July 23, 1963 [July 23, 1962], No. 29221/63. Heading H2E. [Also in Divisions B3, B8 and F2] For use, e.g., in cable jointing, a tubular member of heat-recoverable material, such as polyethylene or P.T.F.E., having the property of elastic memory and in deformed unstable condition, has fusible material arranged in the path of its recovery, and may also contain solder. By virtue of its deformed state, the member may readily be placed around conductors to be jointed; it is then heated to cause the recoverable member to return towards its original shape and size so as to enclose the joint, and to melt the fusible material and the solder, if present. The fusible material, which may be in the form of a member of, say, thermoplastic, or of powder applied to the recoverable member, produces a seal and the solder connects the conductors. Unstripped plastic-covered wires 11 may be jointed by placing them in a tubular heat-recoverable member 8, Fig. 5, having one end closed by moulding or sealing and a lining 9 of thermoplastic capable of bonding to the insulation of the wires. A ball 10 of solder and flux is held within the member and when the assembly is heated, preferably by high-frequency induction heating, the insulation migrates from the ends of the wires, a soldered joint is formed and the material 9 encloses the join as the member 8 contracts to its original form. The tubular member may be open at both ends for joining coaxial wires and a short rigid tube may be provided in the centre of the fusible lining, Fig. 7 (not shown). Alternatively, the tubular member may be formed, Fig. 12A (not shown), so that in use the solder will flow around the conductors to be jointed and will help to force their insulation away from their ends, and the fusible material may be provided at the open end to prevent escape of the solder. The joint between the conductors may be effected by crimping or twisting instead of by soldering and the recoverable tube may be formed by spirally winding a sheet. A fusible member, Fig. 11 (not shown), having a number of passages may be used when several conductors are to be jointed independently. The member has many other applications (see Divisions B8 and F2).

Title: Improvements relating to vacuum braking apparatus
IPC: B60T8/32
Filed: 1935-10-24
Abstract: 464,780. Fluid - pressure brakes. KERSHAW, A. G., SIMMONS, A. W., and WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. Oct. 24, 1935, No. 29367. [Class 103 (i)] In automatic vacuum-brake apparatus communication between the lower chamber of the brake cylinder and the train pipe or atmosphere is electrically controlled by the driver and communication between the upper chamber of the brake cylinder and the atmosphere is automatically controlled by the retardation produced by the braking. The lower chamber 15, Fig. 2, of the brake cylinder 11 is adapted to be connected to the atmosphere by an application valve 9 to apply the brakes and to the train pipe 1 by a holding valve 10 which is closed to hold the brakes applied. A blowdown valve 20 is adapted to connect the upper chamber 23 of the brake cylinder 11 to atmosphere to release the brakes and is controlled by a retardation pendulum 34. To apply the brakes the manual controller 3 is operated to energize the application wire 4, and valves 9, 10 from the supply wire 31. The valve 9 on each vehicle of the train is opened and valve 10 closed to apply the brakes. To hold the brakes applied controller 3 is moved to de-energize wire 4 and valves 9 and valves 10 are maintained closed, valve 10 by energization of the other coil 14 by the holding wire 5. While the brakes are being applied, the retardation may be sufficient to cause the pendulum 34, Fig. 1, to swing away from contact 35 to engage contact 40, whereupon coil 36 of a contactor 38 is de-energized to de-energize the application wire 4 and application wire 5 is energized, thus holding the brakes applied. Further retardation causes the pendulum to leave contact 40 to engage a contact 41, thus de-energizing contactor 39 thus de-energizing the blow-down wire 7 and the blow-down valves 20, Fig. 2, which open to connect the upper chambers 23 of the brake cylinders 11 to the atmosphere, and also close the connection between the chamber 15 of the brake cylinder and the train pipe. The train pipe 1 is adapted to be connected to atmosphere to give pneumatic brake application by deenergization of valve 46 which is normally energized by connection to supply wire 31 by controller 3. This connection is broken on movement of controller to application position but energization is maintained by interlock wire 8, circuit through which is completed by contact 50 of valve 10 and contact 51 of valve 20, and a connection 52 to train wire 6 leading from supply wire 31. If valve 10 or valve 20 fail the valve 46 is de-energized by contact 50 or 51 and a pneumatic application takes place. An additional brake cylinder 53 is controlled by the valves 9, 10.

Abstract: 957,713. Waveguide Faraday rotators. GENERAL ELECTRIC CO. Ltd. Aug. 22, 1960 [Aug. 28, 1959], No. 29538/59. Heading H1W. [Also in Division G3] The ferrite Faraday element 2 is subject to a steady magnetic field upon which is superposed a sinusoidal variation, the amplitude of the steady field being controlled in dependence upon the amplitude of the varying signal pick up by one of two probes 7, 8, this field being such that the input wave is switched to one or another of a pair of outputs 25, 26. The sinusoidal variation is provided by a coil 10 and the steady magnetic field by coils 3, 4, the amount of rotation being proportional to the difference in the currents circulating in the two latter coils. The orientation of the input waveguide 5 and of the probes 7, 8 is such that, when the rotation is zero, the plane of polarization of the transmitted wave lies at 45 degrees to both the probes. The probes 7, 8 are associated with rectifiers 9 and the rectified outputs are fed back to respective coils 3, 4 through two parallel amplifiers controlled by a switch in such a manner that only one amplifier is operative at a time. When the plane of polarization is in the plane of the operative probe the current supplied to the operative coil is zero. If the plane of polarization is not in the plane of the probe a positive current is supplied to the coil, the gain of the loop being such that a rotation of 45 degrees is effected. Depending upon whichever amplifier is operative, the plane of polarization can be rotated through 45 degrees towards either probe, whereby switching between two outputs may be effected. Both of the outputs 25, 26 may be connected to useful loads or one of them may have a dissipative termination. The element 2 may consist of manganese magnesium ferrite and may comprise a series of short rods glued together. Alternatively, an annular member lying in contact with the waveguide wall may be used.

Variable-speed gearing.-In a motor-cycle engine a four-speed-gear is enclosed in a case attached to the crank case, only six-toothed wheels being used for the gearing and for the transmission from the crank to the drive shaft. The usual plate clutch 2 connects the engine crank. shaft 1 to a sleeve, on which is keyed a dog clutch 3. This engages either one of the wheels 4, 5 which are in mesh with the two integral wheels 6, 7, these wheels in turn mesh with wheels 9, 10 free on the driving shaft 11, but adapted to be coupled thereto by the sliding dog clutch 12. The two clutches are worked by a single lever 13, Fig. 3, through the rod 15; lateral movement of the rod carries with it the fork 16 and adjusts the clutch 3; rotation of the rod 15 does not affect the fork 16, but through the screwed muff 17 keyed to the rod and the sleeve 21 the fork 22 is displaced, thereby adjusting the clutch 12. The rod 15 carries at the end remote from the lever 13 a piston 24 slidable in a sleeve 23: this sleeve with a cover 30 is ad. justably secured to the cover plate 19 by a gripping flange 32. The sleeve has a slot 27 Fig. 4, along its length and the cover has grooves 29, parallel to the slot.. A spring pin 26 carried in the piston 24 passes through the slot 27 and with the grooves 29 acts as a lock to the control lever. There may be sets of grooves 29 to allow for replacement after wear. At each change of gear the lever passes through a neutral position. The gear-wheels &c. are contained in an extension at the side of the crank casing 14, the cover plate 19 carrying the side bearings; the plate clutch 2 is within an extra casing 42. By removal of the casing 42 the plate clutch can be dismounted.
