Title: A combined stop and reversing valve
IPC: F16K11/20
Filed: 1919-02-20
Abstract: 137,935. Swinson, E. A. S. Feb. 20, 1919. Reversing-valves.-A combined stop and reversing valve for steam-engines and other purposes comprises a hollow piston valve PV having two heads V<1>, V<2> adapted to pass over two ports ES, EX and having upper and lower bevelled faces adapted to seat on corresponding faces in the valve casing. In the position shown, steam can pass from the inlet S through the valve and the port ES to the engine, the exhaust at the same time returning by the port EX round the valve, and out by the port EP to the exhaust. The flow through the ports ES, EX is reversed by moving the valve into its uppermost position by the handwheel screw HW. The inlet S can be closed independently by a valve V operated by a second wheel attached to a spindle VS passing axially through the main valve spindle HS.

[Class 100 (ii)] Stereotype matrices are prepared by embossing comparatively small sections only at a time, sections of type being set up in a holder which is positioned over a table on which a flong is mounted so as to be adjustable to bring any desired portion beneath the type. The type is set up in a holder 23, being centred therein by jaws 25 actuated by a screw 26 and locked transversely by a pivoted jaw 28 which enters slots in the jaws 25. The holder is carried by a rocking-member 21 pivoted by means of half-round pintles 22 in partcircular bearings in side frames 20, the bearings being arranged so that the member 21 can move therefrom vertically downwards. Crank-pins 41 on the pintles 22 are connected by links 36 to eccentric portions on a shaft 35, so that counterclockwise rotation of the shaft from the position shown in Fig. 2, causes the member 21 to rotate to bring the type face downwards and then to move downwardly to impress a matrix supported on a table 3. The matrix is adjusted by means of guides 4, 5 which may be graduated and are actuated by screws 8, 15 respectively arranged to give a movement of one em to the guides for each rotation of the screws; gauge wheels 16, graduated in fractions of an em, may be attached to the screws 7, 15.

Abstract: 1,151,821. Polyimide fibres. IMPERIAL CHEMICAL INDUSTRIES Ltd. 30 Jan., 1968 [30 Jan., 1967], No. 4481/67. Addition to 1,121,325. Heading B5B. Polyamide acid or polyimide fibres or filaments are dry-spun from the aqueous solutions according to Specification 1,121,325 which relates to aqueous solutions of a salt of a polyamide acid with at least the stoichiometric amount of a salt-forming organic base required to neutralize all the free carboxyl groups. "Polyamide acid" is defined as a polycondensate of a diamine and an at least tri-carboxylic acid having at least two of the COOH groups on adjacent carbons wherein only 2 of the carboxyl groups are involved in the polycondensation. Spinning is preferably effected by the procedure of Specification 1,038,738, which gives rise to polyamide-acid fibres which are partially converted to polyimide but still capable of orientation. The filaments may be partially oriented before conversion to polyimide followed by further drawing to the desired full orientation. Full conversion to polyimide may be effected by heat or by chemical conversion.

Abstract: 475,407. Television; copying- telegraphy; discharge lamps. KNUDSEN, H. Feb. 17,1936, No. 4815. [Classes 39 (i) and 40 (iii)] In telephotographic apparatus, such as television or copying-telegraph apparatus, scanning of a moving film 15 passing through a gate 13 provided with a slot 14 is effected by means of an endless metal band 8 which is formed with a series of slots 12, and is traversed through the gate in a direction at right-angles to that of the film. The band is driven by a sprocket pulley 7 mounted on a shaft 4 driven by a motor 6, the band also passing round a pulley 9 on a shaft 5, the two shafts being supported on a base 1 by brackets and bearings 2, 3 respectively. The film is driven by a sprocket wheel 16 carried by a shaft 17 which is provided with a worm wheel 18 meshing with a worm 19 on the drive shaft 4. The film is taken off and received on drums carried below the base 1, the receiving drum being driven by means of a belt 22 which passes over a pulley 21 on the shaft 17. The gate 13 is mounted at its corners on vertical supports 23, each pair of which is slidably mounted for adjustment of the gate on a pair of horizontal guide rods 24 secured at their ends to the bearings 2, 3. A block 25, adjustably mounted between springs 28 and nuts 29 on the upper ends of the rods 23, carries a U-shaped reflector casing 27 containing, when the device is used as a transmitter, a tubular light source 26, and a lens 30 of substantially rectangular shape, the lower end of the casing being loosely fitted with a shroud 31 which rests on the gate 13. The lamp 26 is mounted at each end in cylindrical perforated members 32 one of which is surrounded by a housing 34 connected with a pipe 35 through which air is pumped to cool the lamp. The pipe 35 is also fitted with a jet or jets 36 adapted to impinge air on to the apertures 12 in the band 8 and the pulleys 7 and 9 may each be formed with a circumferential groove 38 to prevent dirt clogging in the apertures. A photo-electric cell 40 is mounted in a block 41 carried below the gate 13 on the rods 23. When employed as a receiver, the cell 40 is omitted and the lamp 26 replaced by a neon argon lamp or like variable light source.

Abstract: 981,303. Time switches. F. MORSCHEL. Feb. 9, 1961, No. 4843/61. Heading H2B. A time switch driven by an electric motor 2 through a clutch 3 has a spindle 5 that rotates to allow a member 21 to actuate a switch 25 via a roller 26. When the clutch is disengaged a return spring 11 restores the spindle to its initial position. The clutch is operated by an electromagnet (not shown) acting through a coiled compression spring. If the electromagnet fails to release a pin 30 engages a ramp 29 and raises the spindle, thus releasing the clutch. To alter the timing a button 18 is depressed and a pin 20 enters a hole in the member 21 which can then be moved to a new location. A further arm (not shown) also engages the switch.

Abstract: 571,277. Endless-belt conveyers. PALMIER, A. R., and BAKER PERKINS, Ltd. March 35, 1943, No. 4862. [Class 78 (i)] Means for discharging dough or like plastic pieces from a conveying belt or surface 1 comprise a bar or roll 4 adapted to be moved across the conveying surface and means for imparting a rotary motion to the roll while it engages the dough piece to provide a lifting and rolling motion to the dough piece. In the construction shown a conveyer belt 1 extends across the face of a dough prover having pockets 2 into which the dough, pieces from the belt are fed by a reciprocating roll or bar 4 carried by arms 5 fixed on a shaft 6. An arm 8 on the shaft carries a roll 9 engaging a cam 10 on the driving shaft 11 of the conveyer, so that the bar, is moved to-and-fro across the face of the belt 1. The shaft 6 is so situated relatively to the belt that the bar 4 rises as it moves across the belt to deliver the dough pieces to the pockets 2; at the same time the bar 4 is rotated by means of straps 14 which pass round the bar and over pulleys 22, and are fastened at one end to brackets 16 and are kept taut by springs 15. The belt 1 passes over a table 3 which has an extension 20 bridging the gap between the belt and the pockets 2. A back aboard 21 prevents the dough pieces from being thrown past the pockets. In a modification, Figs. 5 and 6 (not shown); the arms are mounted on a shaft above the belt instead of below, and the roll 4 is rotated positively by chain gear and a spur wheel engaging a fixed sector wheel.
