Title: Improvements in and relating to valve seating arrangements
IPC: F16K1/42
Filed: 1958-05-22
Abstract: 858,315. Valves for reciprocating pumps. DRESSER INDUSTRIES Inc. May 22, 1958 [May 31, 1957], No. 16450/57. Class 102(1). [Also in Group XXIX] In a valve for use with a piston type pump, e.g., a slush pump, a metallic valve seat ring 4 pressed into the valve body 1 and having a conical seating face 10, is formed with an external peripheral groove 15 mounting a resilient sealing ring 13 which is held in the groove by a metallic locking ring 16. The ring 13 which is made symmetrical about a mid horizontal plane to permit of its reversal in case of wear is formed with upper and lower faces 12, 12A converging inwardly toward the ring centre and lips 14, 14A. The face 12 (or 12A) stands slightly proud of the face 10 so that impact forces on the closure of the valve are first taken by the resilient ring. The lip 14 (or 14A) provides an undersurface subjected to the pressure in the chamber 2 such that when the valve element 8 is seated sealing of the valve is further enhanced.

Title: Machine for folding or bending thermoplastic sheet materials
Inventor: CARTER ALBERT EDWARD
IPC: B29C53/04
Filed: 1955-06-09
Abstract: 835,694. Forming thermoplastic sheets. CARFIELD (ENGINEERS) Ltd. Sept. 10, 1956 [June 9, 1955], No. 16546/55. Class 87(2). A machine for folding thermoplastic  sheet material has means for supporting the sheet and heating it to soften it along the desired fold line, means for pressing the softened sheet about the heating means, and means for setting the fold by cooling. The cellulose acetate or other thermoplastic sheet S is laid on an inclined table 37, Fig. 1 above a pivoted transverse lifting bar 38, with its lower edge resting against a stop 11 on a rear folding bar 10 lying across the frame 1 of the machine. A front folding bar 12 also lies across the machine. Both folding bars are adjustable, leaving a transverse slot between them, and are of stainless steel, large enough to absorb heat rapidly. A treadle, not shown, is depressed and causes a forked arm 24, Fig. 3 carrying a pin 23, to withdraw the pin from a recess in a plate 21 and engage a toothed clutch 25. A shaft 20 is thus driven through gearing and rotates a cam 19, to which the plate 21 is attached, and cams 32 at the end of the shaft. The portion a to b of the cam 19, engaging a roller 18 supported from a cross bar joining the ends of levers 14, turns the levers about pivots 15 and causes them to lower a blade carrier 4 in slideways 3, so bringing the blade down on the sheet S. In the movement of the cam from b to c the blade dwells on the sheet and is heated by an electrical element in the blade carrier, controlled by an adjustable thermostat, the sheet thereby being softened along the line of the blade. Movement of the cam from c to d depresses the blade into the slot between the folding bars 10, 12 and the sheet is therefore folded along the softened line, the blade remaining there during the cam travel d to e while the material cools and sets. In the travel e to a the levers 14 are operated to raise the blade carrier, and the cycle is completed by the pin 23 dropping back into its recess and allowing the clutch to be disengaged by a spring 26. The folding is assisted by the lifting bar 38, which is pivoted to raise the sheet as the blade carrier descends by rods 39 thereon engaging the tail of the lifting bar side arms 40. In the last part of the cycle the cams 32 operate push rods 34 the upturned ends of which push the folding bar 12 forwards against a spring 36, so releasing the folded sheet which drops into a receptacle.

Title: Improvements in or relating to photolithography
Inventor: SPENCER ALEXANDER
IPC: G03F7/06

Abstract: 793,550. Photolithography. GESTETNER Ltd. May 15, 1956 [June 9, 1955], No. 16674/55. Class 98(2) A plate having an oleophilic surface carrying a layer of unhardened gelatinosilver halide emulsion is imagewise exposed, developed in a developer which partially hardens the gelatin in the exposed areas, treated as with warm water to uncover the oleophilic surface in the unexposed areas, treated with a lithographic etch and inked, whereby ink is held only in the uncovered oleophilic areas, and then used for offset lithographic printing. The exposed areas, which therefore have to be developed to a state hard enough to be not removed by warm water but not so hard as to become oleophilic correspond to the high-lights of an original, and the final printing plate may result from direct camera-exposure using a reversing prism, or other exposure from a positive original. In Example 1 a cellulose triacetate film base is subbed with a specified rubberresin layer, provided with a gelatino-silver chloriodide layer a mixing for which is quoted, exposures effected in a process camera and development in a specified pyrocatechin developer, preferably development is halted as by acetic acid and the film is then washed in warm water, dried, and further treated as outlined above. In Example II a similar film base is provided with a gelatin subbing layer and then an emulsion layer of the character used in Example 1, and is exposed and developed similarly; it is then re-exposed to overall illumination, developed in metol/hydroquinone and treated in a specified etchbleach to remove unhardened emulsion and underlying gelatin, leaving a negative record in hydrophilic relief which is treated as in Example 1 for lithographic procedure.

A machine forms a valve block bottom on the open end 6 of a block bottom bag in a continuous sequence of operations including securing cover sheets over both block bottoms. The bags 1, as shown in Fig. 2, are fed by a suction cup 2 each to a gripper 3 on a drum 4 and brought with their open ends above a conveyer belt 7. Co-axial with the drum 4 are two oppositely rotating discs 8 and the bags are pressed against these by rollers 10, causing them to be withdrawn from the grippers and be advanced by belts 7, 17 with their open ends forward. Each bag abuts an aligning stop 18 travelling at a lesser speed and is then advanced by a segment 19 to rollers 21, 22 and cutters 23, 24 which latter form a cut-out 25 at the open end. The bag passes through rollers 26, 27 to a roller 28 having a motion cup, and is drawn against the periphery of a drum 31. The open end of the bag is gripped on one side by one of a series of suction tubes 29 on the drum 31 and on the other by the cup on the roller 28 so that it is opened out enabling folding elements 33, 34, 36 to form the bottom square. A roller 41 imprints a glue area 43, Fig. 4, and a valve sheet 44 is applied to the area by a cylinder 48. Glue areas 52 are next imprinted by a roller 51 and creases 55, 56 formed by devices 57-59 and 60, 61 respectively. A rod 62 moving faster than the drum folds part 53 inwards about the crease 55, a member 65 then pressing it down. A rod 66 now folds down part 54 and a roller carrying gluing strips 71, 72 applies glue areas 67, 68. Cylinders 78, 84 transfer cover sheets 85, 86 to the block bottoms from magazines 73, 79. The completed bags are removed from the drum 31 by grippers 87 on a cylinder 88 and carried past pressure rolls 91 to belts 89, 90 for exit from the machine.
