Title: Method for producing a finished, reinforced edge on flexible webs or sheets
IPC: D04H1/44
Filed: 1963-09-04
Abstract: 998,120. Strengthening edges. CLUETT, PEABODY & CO. Inc. Sept. 4, 1963 [Sept. 4, 1962], No. 34949/63. Heading B5K. The edge of a web is compressed inwardly upon itself and set in this position to improve the tearing resistance of the edge. As shown, a square sheet of non-woven fabric or paper 10 is laid on a bed plate 14 having a roughened raised bead 16 to engage the sheet 10 just inside its edges. Dies 18 operated by pneumatic piston-cylinder arrangements 19, are then moved inwardly and their undersides engage the top surface of the margins of the sheet and press it downwardly on to the roughened surface 17 to prevent inward movement of the sheet. Further inward movement of the dies compresses the edges of the sheet. If the fibres of the sheet are thermoplastic these are softened by steam from a duct 27 and by heaters 28 and the edge is thus set in its compressed state; otherwise layers of adhesive, e.g. of resin, are formed on each face of the edges of the sheet before compression and act in a similar manner. Tablecloths, napkins and handkerchiefs of non-woven fabric or paper may thus be made. Details are given of suitable mixtures of fibres.

Filed: 1968-07-23
Abstract: 1,240,480. Valves; bearings. DAIKIN KOGYO CO. Ltd. 23 July, 1968 [17 Aug., 1967; 4 Dec., 1967], No. 35187/68. Headings F2A and F2V. A sliding plate type valve comprises a body 15, 16 having a pressure inlet port P, a tank port T, and two utilization ports (A, B) not shown, for controlling the supply and exhaust to and from a cylinder actuator or the like. As shown, the valve is of rotatable disc type, including a valve disc 32 engaged by pins 26 carried by an actuating stem 28. With the object of avoiding leakage into the valve chamber 18 in intermediate or transitional positions of the disc, a floating plate 36, which is slidably mounted on pins 42a, 42b, in interposed between the disc 32 and tubular seat members such as 45P, 45T. These seat members are biased by springs 46P, 46T and by the fluid pressure to engage the plate 36. This plate has four equiangularly spaced slots 35P, 35T and (35A, 35B), Fig. 7 (not shown) communicating with circular ports 45b. The disc 32 has two diametrically opposite arcuate slots 30, 31. The seat members are sealed by rings 47, 48. The valve may be of the type in which all ports are closed in neutral (Fig. 8), or by increasing the circumferential extent of the slots 30, 31, it may be an all port open type wherein all ports are communicated with each other in neutral, Fig. 9(b) (not shown). Alternatively, a tandem centre type wherein port P communicates with port T but port A does not communicate with port B in neutral, is obtained by forming two passages (56, 57) in the disc (32) which open at four ports (58 to 61) at the disc face, Figs. 10a and 10b (not shown). Inching grooves (30a, 31b) may be formed at the ends of the slots 30, 31. In the embodiment shown, the valve chamber 18 is drained externally through a connection 52 and a small bore passage 40 in the plate 36. An internal drain type may be obtained by omitting the seat member 45T so that the chamber 18 is in permanent communication with the port T. In a modification, Figs. 12 to 14 (not shown), friction between the disc 32 and plate 36 is reduced by an interposed roller thrust bearing (103). This bearing surrounds a sealing plate (102) ported to match the disc (32) and bolted to it. The thickness of the sealing plate (102) is made about 10 microns less than that of the thrust bearing so that leakage is negligible. The seat members may be positioned partly in the body 16 and partly in the plate 36 or may seat on the body 16. The arrangement of porting shown in the plate 36 develops a fluid pressure force urging the plate toward the disc. In another embodiment, Fig. 17 (not shown), the invention is incorporated in a rectilinear slide valve in which the slide (146) is retained in actuated positions by a detent.
