Title: Improvements in or relating to the edgewise joining of sheets
IPC: B27D1/10
Filed: 1953-06-25
Abstract: 745,453. Seaming non-metallic sheet material. KOK, G. J. M. June 24, 1954 [June 25, 1953], No. 17672/53. Class 42 (1). A method of effecting the edgewise joining of sheet material, e.g. veneers, whose adjacent edges have had glue applied to them, comprises passing a sheet in a direction normal to its edges to be joined, halting the passage of the sheet as the trailing edge is in position adjacent a heating element securing the sheet in the halted position, passing another sheet in the direction of movement of the first sheet until its forward edge abuts the trailing edge of the preceding sheet in position for heating, applying heat to the abutting edges of the sheets to effect setting of the glue whilst applying pressure to the sheets to urge the adjacent edges of the sheets together, and thereafter advancing the joined sheets until the trailing edge of the second sheet is in position for joining a further sheet. In the apparatus shown, a first veneer sheet is taken in by rollers 2 and drawn through by rollers 3 (pairs of rollers situated on both sides of machine) until the trailing edge is in position for joining a succeeding sheet to it. Stopping of the sheet is controlled by feeler or photoelectric mechanism and the sheet is then held in position by a pressure element 5 actuated by a hydraulic cylinder 18. A second veneer sheet is then taken in by rollers 2 and when in position a pressure element 6 is actuated by a hydraulic cylinder 20 so as to clamp the second veneer in place and press it against the first veneer. When the veneers are in position heating elements 7 and 8 are moved towards the adjacent edges of the veneers by a hydraulic cylinder 15 through levers 16 and 17. The operations then take place in the reverse order, the glued veneers are fed forward until the trailing edge of the second sheet is in position for gluing on a further sheet and so on. The sequence of operations is controlled through a timing clock.

Filed: 1972-04-18
Abstract: 1387210 Seals PHILIPS GLOEILAMPENFABRIEKEN NV 18 April 1972 [21 April 1971] 17862/72 Heading F2B In a device in which a liquid-supported rolling diaphragm seal 3 is arranged between relatively reciprocating elements, the liquid present as, for example, the rod element 1, is pumped to the space 5 for the supporting liquid by a metal sleeve 6 which is urged towards the rod element by a metal ring 8 at a zone adjacent that end of the sleeve which is nearer the rolling diaphragm. The pumping sleeve 6 pumps liquid past the.sleeve to the space 5 by a hydrodynamic effect and also operates as a non-return valve to prevent the flow of liquid from the space 5, the end of the sleeve being pressed against the rod 1 by the clamping ring 8 which may be made of brass. To ensure a good seal a sealing ring 9 is mounted on the end of the sleeve by an 0-ring 13, the ring being of flexible material and urged into contact with the rod by a garter spring 12. The 0-ring and spring may be omitted. A control device 15 ensures that liquid can be removed from the space 5 to maintain a constant pressure differential across the rolling diaphragm 3. The sleeve 6 and ring 9 may be retained in the rod, instead of in the housing element 2 to act outwardly against the housing element.
