Title: Improvements in or relating to the production of plates or walls of pressure containers
IPC: B21D51/24
Filed: 1949-12-13
Abstract: 662,924. Making pressure containers. MUNTERS, C. G., and BERNER, E. Dec. 13, 1949 [Dec. 13, 1948; Dec. 8, 1949], Nos. 31945/49 and 31946/49. Class 83 (ii). [Also in Group XXVIII] Plates for the curved &c. walls of pressure containers such as boilers, barrels, ships' hulls, submarine structures, firearms, &c. are corrugated in such a manner that on applyingpressure the corrugations are straightened before the plate ruptures. A pressure container made from a plate 10, with butt-welded longitudinal seam 20, is corrugated in sine form with depth of corrugation 0.05 to 0.1 times the external radius of the container. The number of corrugations varies from 4 to 8, depending on the proportions of the container. The wall thickness is determined by a modified thin cylinder formula. The container may be reinforced longitudinally by welded internal or external bars or by integral ribs. After fabrication the internal pressure may be increased in stages and the pressure reduced to zero between the stages. The corrugations may extend radially across the ends in which they die out towards the centre.

Title: Injection molding apparatus
IPC: B29C45/56
Filed: 1948-12-10
Abstract: 652,526. Injection-moulding apparatus. LESTER ENGINEERING CO. Dec. 10, 1948, No. 32050. [Class 87 (ii)] An injection moulding apparatus comprises a mould cavity C fed from an injection cylinder 10 which, in turn, is fed by a filling or plasticizing cylinder 26, the injection cylinder being movable between a normal position as shown in Fig. 3 in which it is in communication with the filling cylinder and cut off from the mould, and the reverse position as shown in Fig. 4, in which it is cut off from the filling cylinder and in communication with the mould. The cylinders are heated in the usual manner. Granular moulding material is fed into the filling cylinder 26 through hopper 36 in the discharge spout 37 of which is a gate 38 which is reciprocated, so as to open or cut off feed, in unison with plunger 30, through member 47 engaging stop 49. The material entering passage 39 at each stroke is accordingly discharged into the annular space round spreader 27, 28 when plunger 30 is in the raised position and eventually forced in a fluid state through nozzle 25 into cylinder 10. Downward movement of plunger 15 through lost motion 21, 22, forces cylinder 10 down against compression spring 12 so as to cut off the filling nozzle 25 and open the cylinder 10 to the mould inlet 6. The mould is constituted by a fixed die 2 and a movable die 3. The latter is provided with excess material reservoirs 60, 61, 62 in which are fitted plungers 63, 64, 65 which are normally under the pressure of their compression springs but, on the completion of the injection stroke and, preferably, after the injection cylinder has been cut off from the mould, extra pressure is applied by the plungers through the introduction of fluid pressure to chamber 69. An automatic timing device, Fig. 5 (not shown), controls,'through the media of electrical timers and solenoid-operated fluid-pressure valves, the supply of fluid to cylinders 32, 17 and 69, and the sequence of operations. Specification 540,286 is referred to.

Abstract: 1323784 Electrically released switches; magnetic switches CMC CHARLES MAIER & CIE 8 July 1971 [21 July 1970] 32056/71 Heading H1N An electromagnetic release for an earthleakage circuit-breaker comprises an armature 5 carried on a support arm 6 pivoted on a spindle 3 rotatable in a wall 2 of the breaker housing, the armature 5 being held against two polepieces 7 polarised by a permanent magnet 17 until the excitation of a trip coil 16, Fig. 2, (not shown), reduces the holding force sufficiently for the armature 5 to separate from the polepieces 7 under spring force. Two coil springs 1 and 9 exert a torque and also push axially of the spindle 3 on parts of the armature mounting to prevent all axial movement so that the armature  5 consistently returns to rest in the same position on the polepieces 7. The resetting lever 4 is acted on by parts of the switching mechanism of the breaker to bring armature 5 back on to pole pieces 7 after tripping. The spring 9 exerts its axial pressure between the support arm 6 and a second lever 15 riveted on the end of the spindle 3 and hence pushes arm 6 against a retaining ring 10. The torque of spring 1, which tends to separate armature 5 from polepieces 7, is transmitted to arm 6 through the spindle 3 and a detent 8 on lever 15.

Title: Improvements relating to apparatus for positively locating successive vehicles of a coupled train
Inventor: CUTTLE GEOFFREY
IPC: B65G67/00
Filed: 1957-10-16
Abstract: 857,790. Feeding rail vehicles to and from tipplers and the like; moving railway vehicles; rail vehicle stops. SIMON-CARVES Ltd. Dec. 29, 1958 [Oct. 16, 1957], No. 32308/57. Classes 78 (4) and 104 (2). In a tippler installation of the kind in which mine cars coupled together by rotary couplings are each, in turn, rotated by the tippler without uncoupling the cars from the train, means are provided to positively locate the cars adjacent the entrance and exit of a tippler 1 during rotation of the car or cars in the tippler. A catch 42 and a pivoted catch 43, on the exit side of a tippler 1 (Fig. 2), are moved along a rail 30 by means of an hydraulic ram 40, the rail 30 being raised on links 31, 32 by a ram 35 to bring the catches into the path of a dummy axle 10 on a car. Similarly, on the entrance side of the tippler, a catch 52 is moved by a ram 50 along a rail 47 which is raised by means of a ram 53, and a fixed pivoted stop 25 is mounted on the mine car rails. The rams 35, 40, 50, 53 and a ram 13 for pushing the cars through the tippler may be operated manually or automatically through electrically controlled fluid valves. As the tippler reaches its car receiving position it closes a switch 90 which moves valves 62, 68, 82, 84a to the positions shown in Fig. 2 in which fluid pressure is applied to the right-hand end of ram 13, from the main variable stroke pump 60 controlled through valve 68 by pressure from a constant pressure pump 65, and pressure from the pump 65 extends the rams 35, 53 and retracts rams 40, 50 to lower the rails 30, 47 and to move the catches 42, 52 to the right. On opening of a switch 103 by movement of a carrier 19 attached to the piston of ram 13 and provided with an axle-engaging arm 23, the circuit to valve 84a is opened allowing fluid to pass from the pump 65 to retract rams 35, 53 to raise the catches 42, 52. On further movement, the carrier 19 opens a switch 104 which de-energizes valve 68 cuts off the pressure from pump 65 to control mechanism 69 to move pump 60 to an idling condition, and on opening of switch 105, pressure from pump 65 is applied to the right-hand end of ram 40, holding the catch 42 against stop 24, and to the left-hand end of ram 50 to draw the dummy axle engaging catch 52 back against the stop 25. Movement of the tippler and actuation of the switch 90 may be controlled by gamma-ray devices. For multi-car tipplers, an additional ram 13 is provided for each additional car in the tippler, the rams being connected in series.

Title: Improvements relating to coin-freed mechanism
Filed: 1932-11-15
Abstract: 400,785. Coin-actuated mechanism. CALDWELL, T. F., 12, Stafford Road, Crovdon. Nov. 15, 1932, No. 32329. [Class 27.] Testing coins.- Apparatus for testing the thickness of a coin at the annular space between the rim and the embossed face comprises a pivoted member adapted to be struck by the coin and carrying fixed and movable gauging points adapted to grip the coin at the annulus, the movable gauging point being carried by an arm adapted to engage an abutment if the coin is too thick and to prevent its withdrawal by the gauging points and delivery into a shoot for correct coins. A coin 1 inserted in the shoot 2, Fig. 1, passes between a fixed rear plate 4 and a spring- pressed front plate 7 pivoted on a rod 43. If it is too thin at the rim, it falls between the plate 7 and a ledge 3 on the plate 4 into a return shoot, and if it is of insufficient diameter it falls through an aperture 6 in the plate 7 into the same shoot. If it is too large, it becomes jammed, and may be released by pivoting the plate 7, which is preferably connected with the drawer of vending apparatus which the coin is to operate. If it is of the correct size, it rolls along the ledge 3 and hits an arm 19 pivoted at 20 to the plate 7, swinging this outwardly. The arm 19 is formed with a projection 25, Fig. 7, carrying a fixed gauging point 26, and carries an arm 29 to which is pivoted an arm 27 terminating in a movable gauging point 30. The arm 27 is also formed with a ramp 32, which, as the arm 19 swings outwardly, engages an adjustable projection 33 which moves the arm 27 inwardly and causes the coin to be gripped at the annulus between the gauging points 30, 26. If the coin is of the correct thickness at the annulus, the ramp 32 clears the projection 33, and the coin passes forward and drops into a shoot for correct coins, but if it is too thick, the ramp 32 jams against the projection 33, and the coin may be moved laterally off the ledge by pivoting the plate 7, when it falls into the return shoot. If for any other reason the coin becomes jammed between the gauging points, it may be released by pivoting the plate 7, the rod 43 carrying at its end a projection 42, Fig. 1, which engages a ramp 41 on an upper arm 40 connected with the arm 19 and swings this outwardly. A one-way catch 45 prevents a coin rebounding from the arm 19, which might lead to the passing of an incorrect coin.
