Abstract: 1,231,795. Casting processes and plant. HEPWORTH & GRANDAGE Ltd. 12 Sept., 1968 [4 July, 1967], No. 30692/67. Heading B3F. Piston rings are cast in a plurality of discshaped moulds 1 mounted on a jig J. The moulds 1 are of gas-permeable material, have cavities 2 each with an ingate 3 and gas vents 4 (not shown), all connecting with a central passage 4a through which gases generated during casting pass to the atmosphere. To fill the moulds, the jig is lowered into a bath of molten metal and is immersed to just below the apertures 6a. If the moulds are of less dense material than the melt they will be held together by the upthrust. Alternatively, mechanical clamping can be used by threading a bush 8 and a spindle 9. Casting plant.-In Fig. 4, moulds are prepared and assembled at a moulding station 14 and wheeled to a casting station where they are dipped into melt within a furnace 17 by a reciprocating mechanism 16. The moulds are removed from the jigs at 18 and the jigs return to the moulding station after being dipped in, and coated with, a graphite wash at a station 19.

Abstract: 1,231,853. Mechanical tear-off device. C. E. COOK. 19 Feb., 1969 [4 April, 1968], No. 9063/69. Heading B4B. [Also in Division G4] A dispenser 1, issues tickets, vouchers or stamps from a perforated roll through feed rollers 2, 3 past a serrated tearing edge 6, and through rotatable rollers 8, such that when the dispenser is turned off the rollers 8 keep rotating after the rollers 2, 3 have stopped, thus tearing off the tickets against the edge 6. The rollers 8 continue to rotate after rollers 2, 3 have stopped, either by reason of their greater inertia or by a time delay circuit which switches off the motor driving rollers 8 after that driving rollers 2, 3. Alternatively, rollers 8 rotate continuously. The axes of rotation of the rollers need not be parallel to the edge 6. The dispenser is operated by push-buttons which are actuated manually or by means of solenoids operated by a coin freed mechanism as described in patent Specification 1,231,852.

Abstract: 1316602 Pipe coupling TATARSKY NEFTYANOI NAUCHNO - ISSLEDOVATELSKY INSTITUT 5 May 1970 21641/70 Heading F2G A pipe coupling device is intended to be attached to a compressed air supply via pipe 22 and a swivel coupling 21 to a pipe 4 which is being vitrified. The device comprises a pipe coupling member 1, a coupling 2, a cap 7 which has a packing ring 9 and a valve mechanism 12 which opens automatically upon connecting the member 1 and the pipe 4. As shown the pipe coupling member 1 and coupling 2 are rigidly connected and the latter engages the internal screw thread of the sleeve 3 at the end of the pipe 4. Rotation of the pipe coupling member 1 causes movement of the coupling 2 further into the sleeve 3 whilst the cap 7 is restrained from so moving by the end of the sleeve 3. The cap 7 is connected by rods 13 to a bar 14 having a sliding black 19 so that as the pipe coupling member 1 and coupling 2 advance the block 19 enters valve sleeve 16 and prevents its movement therewith. The subsequent relative movement of the sleeve 16 and the pipe coupling member 1 exposes holes 17 and compressed air may therefor enter the pipe 4 from the pipe coupling device. The cap 7 is held against the sleeve 3 by the action of the spring 8 and adjustment of the force is effected by the nut 20. When the pressure in the pipe 4 exceeds that created by the spring 8 at the seal between the sleeve 3 and the packing ring 9 of the cap 7 the seal is temporarily broken and the excess pressure vented. Disconnection of the device and the pipe 4 is performed by unscrewing the coupling 2 from inside the sleeve 3.

As shown, a pair of U-shaped yokes 1, 2, Fig. 2, straddle a rail vehicle wheel 8 having braking rings 7 secured to opposite sides. Pivoted at 4 between the yokes, on each side of the wheel, is a caliper lever 3, Fig. 1, to which is pivoted in turn a brake shoe 6, Fig. 3, by means of lug recesses 12 which receive caliper lever pins 13, retained in the circumferentially inner parts of the recesses by retaining pins 14. The brake is applied by an actuator 5 which separates the outer ends of the caliper levers 3. The shoes are guided so as to be maintained substantially parallel to the rings 7 by engagement of the outer part of each recess 12 with a squareheaded pin 16 at the end of the respective yoke 1 or 2. When the shoes are new the recesses 12 engage pins 16 in close proximity to the shoe, but as the shoes wear they move progressively inwards along the pin heads. The recesses 12 are at a small angle (e.g. 12 degrees) to the axis of the rings 7 so that on brake application the shoes move slightly radially (see Fig. 2). The brake structure is pivoted about an axis 10, Fig. 1, by a pivot pin (not shown) passing through lugs 9 in the upper yoke 1.
