Title: Improvements in the moulding and jointing of thermoplastic materials for example in the jointing of electric cables
Inventor: BARNES ARTHUR ALBERT WILLIAM
IPC: H02G15/18
Filed: 1949-11-14
Abstract: 676,543. Injection-moulding; making cable joints. TELEGRAPH CONSTRUCTION & MAINTENANCE CO., Ltd. Feb. 14, 1951 [Nov. 14, 1949], No. 29135/49. Class 87(ii) A method of uniting or bonding thermoplastic bodies or bodies having a thermoplastic coating comprises enveloping the bodies (or the parts thereof adjacent the joint to be made) in a mould casing, injecting hot gas into the mould casing to soften the thermoplastic material, and finally injecting thermoplastic material to form the bond between the bodies or build up the coating thereon. The invention is illustrated in connection with the jointing of two electric cable conductors C, C' provided with insulation A which may be polythene. The bared ends of the conductors are joined at B by soldering or brazing, with or without a sleeve, ferrule or the like 2, and a mould in two parts 3, 4 (or more than two parts) is assembled around this joint. Packing and heat-insulating sleeves 9 are provided at the mould ends. Hot gas (air or nitrogen) is then blown into the mould through orifice 6 and escapes through holes 7. A portable electrically-heated blower may be used. The hot gas softens that part 1 of the insulation that is within the mould. Polythene is then injected through orifice 6 into the mould, as by a hand-operated plunger type injector. The injection may be continued until the material has cooled. Fins 8 on the mould facilitate cooling. The injection orifice may open tangentially into the mould. Joints may thus be made in the field or in manholes. Large mouldings of polythene may be made by using a small mould to make part of the moulding and then moulding further parts thereonto by the method of the invention; in a similar way intricate mouldings may be made in two or more operations.

Title: Improvements in or relating to gyro-compasses
IPC: G01C19/38
Filed: 1952-11-21
Abstract: 717,470. Electric compass repeaters. SPERRY CORPORATION. Nov. 21, 1952 [Nov. 21, 1951], No. 29471/52. Class 40 (1). The "speed error" of a gyro-compass, i.e. that due to the velocity of the craft carrying the compass relative to that of the earth's surface, is corrected by driving a compass repeater indicator through Selsyns, and introducing a variable-ratio-mechanical coupling between the parallel shafts of two of the Selsyn elementsthe coupling ratio varying according to the lateral spacing of the shafts which is adjusted in dependence on craft speed and latitude. Fig. 1 shows the craft velocity V added vectorially to the earth's surface velocity Rw cos L, where R is the earth's radius, w its angular velocity and L the craft latitude, to produce the resultant craft velocity. Since the gyrocompass aligns itself perpendicularly to the resultant velocity it will indicate the apparent heading H' instead of the true heading H. Fig. 2 shows the same vector triangle in which each vector has been multiplied by secant L so that the earth's velocity vector Rw is of constant. magnitude and latitude variations affect the vector V sec. L, this vector triangle being solved by the apparatus of Fig. 4. Corrector construction, Fig. 4.-A Selsyn receiver 1 is set by a servomotor 11 according to the erroneous compass heading H<SP>1</SP> by the gyro-compass-driven transmitter 34 (not shown). The drive from the servomotor 11 to the rotor shaft 4 of the receiver 1 is effected through a. disc 8, an eccentric pin 9 carried thereby, and a slotted radial arm 5 carried by the shaft 4. The radial distance between the shaft 6 of the disc 8 and the eccentric pin 9 corresponds to- Rw. The shafts 4, 6 are axially aligned for zero latitude, and shaft 4 is displaced laterally with a slide 2 carrying the receiver 1 in accordance with V sec. L. The slot in the arm 5 is parallel to the direction of slide movement forcompass headings of due East or West, so that. the variable motion coupling 5, 9 sets the disc: 8 according to the true heading H which may be Selsyn transmitted at 7 to compass repeaters 35 (not shown). The slide 2 may be set by a servo-motor 15 controlled by manually set craft latitude and speed elements 22, 27. Adjustment of the speed knob 27 rotates a helicalribbon like armature 25 to unbalance an E type transformer pick-off 12 which through a phase sensitive amplifier 14 controls the motor 15. The pick-off 12 is also connected mechanically with the slide 2 by a lever 16 pivoted about a pin 17 the vertical position of which is set in accordance with sec. L by the latitude manual control 22, so that the slide is moved in accordance with V sec. L. The speed adjustment may alternatively be effected automatically e.g. electrically from a Pitometer log 32.

Abstract: 208,131. Soc. des Trains Chenard et Walcker, F. A. R. Dec. 5. 1922, [Convention date]. Couplings for road vehicles.-In trailer vehicles having a longitudinally slidable coupling hook connected to the brakes so that they are applied when the trailer over-runs the tractor or other preceeding vehicle a strong spring or buffer is so disposed as to urge the vehicles apart and thus prevent the application of the brakes on the trailer except when the forward vehicle is abruptly slowed or in the event of the coupling breaking. A screw 2 mounted on the tractor vehicle 1 and actuated by bevel gearing, 3, 3<1> carries a nut with a flanged part 5 supporting a coupling hook 6 which is slidable in guides on the coupling bar 7 of the trailer vehicle. The hook 6 is connected by the cable 8, lever 10, and rod 12 to the brake 14. A spring 9 applies the brake when permitted to do so by the inward movement of the coupling hook 6. Upon the coupling bar 7 is mounted in guides 18 a rod 16 urged forwardly by a spring 19 strong enough to hold the tractor and trailer vehicles apart when the tractor vehicle is gradually slowed, If however the tractor vehicle is abruptly slowed, the spring 19 is overcome and the consequent inward movement of the coupling hook 6 causes the brakes 14 to be applied. The buffer 16, 19 may instead be mounted upon the tractor. If the coupling breaks the brakes 14 are automatically applied.
