Abstract: 1,063,858. Vacuum sealing thermoplastic containers. M. SCHMIDT. Dec. 18, 1963 [Dec. 18, 1962], No. 50084/63. Heading B8C. A cover sheet 23 (Fig. 1) is welded to the periphery of a tray 27 by welding means 24 mounted within a vacuum chamber 3. In the apparatus illustrated the sheet 23 is withdrawn from a reel 26, and passes through the chamber to a reel 33. The open-topped tray, which may be multicellular, is placed on a support 20 by a pair of grippers 25, and then the two halves of the chamber are moved towards each other by pneumatic rams 6, 7, thus closing the chamber and trapping the sheet 23. The welding means 8 and 10 are mounted on the halves 2 and 3 of the chamber so that as the chamber closes they are moved towards each other, without meeting, the lower welding tool 10 raising and supporting the tray along its rim. Air is then extracted from the chamber via tubes 14, and if necessary the chamber can be filled with nitrogen via the tube 18. The heating tool 21 plasticizes the cover sheet 23, and after a further downward movement of the welding tool 24, which is provided with teeth, the cover sheet is welded to the peripheral edge of the tray and is also perforated along the upstanding rim (Fig. 2, not shown). The chamber is then opened and as the tray is moved from the chamber the cover sheet tears along the perforation. The waste cover sheet is taken up by the reel 33. Alternatively, if the cover sheet is the same width as the tray, the reel 33 and the teeth 24<SP>1</SP> can be dispensed with, the cover sheet being cut transversely between the trays by a knife or shears.

Abstract: 1,072,850. Circuit assemblies. UNITED AIRCRAFT CORPORATION. Dec. 24, 1963 [May 27, 1963], No. 50893/63. Heading H1R. An electronic sub-assembly comprises two wafers (16, 18, Fig. 3, not shown) of glass, ceramic &c., e.g. quartz, sapphire, forsterite, zirconium, or preferably alumina or beryllia, and an intervening mica sheet (20), the three layers having registering co-ordinate arrays of vertical through holes, and the wafers (16, 18) having peripheral horizontal holes which open into the outer vertical holes. The wafers (16, 18) and the walls of the holes therein are coated with metal, e.g. chromium overlaid with gold, by vapour or vacuum deposition, and the coatings on the inner surfaces of the wafers are scribed by electron beam etching or photoetching to form conductive paths and thin film passive circuit elements. The coatings on the outer surfaces of the wafers, as shown in Fig. 8, are scribed to form terminal pads which are plated with nickel. Plug-pins 56 are placed in selected horizontal holes, and the vertical holes of the assembly are filled with brazing alloy by suction or immersion in molten alloy; alternatively, solid metal is inserted in the vertical holes and melted by electron beam or firing, or the holes are filled with expandable dental-type alloy. Components 50, 52, 54 are mounted on the outer surfaces of the wafers, their leads being electron beam welded, or soldered, or brazed to the nickel-coated terminal pads; components 50 are functional blocks which are located in grooves 12 in the wafers. Finally the assembly may be hermetically sealed in cans. Instead of the mica sheet (20), a ceramic insulating plate may be used, or the inner surface of one wafer may be left uncoated with metal. Grooves may replace the horizontal holes to receive pins 56. Two assemblies may be joined by the interposition of a ceramic frame-shaped member (58, Fig. 9, not shown) having vertical holes to register with the outer vertical holes of the assemblies.

Abstract: 1462679 Fluid-pressure actuators POCLAIN 25 Nov 1974 [3 Dec 1973] 50940/74 Heading F1D A telescopic actuator, Fig. 2, comprises a cylinder 1b in which slides a piston 3b with a hollow rod 4b, and a piston with a piston-rod 9b which slides in the hollow rod 4b, the arrangement being such that the two rods protrude from opposite ends of the cylinder when extended. When a valve 30b is moved to the position shown, fluid is fed through conduits 32, 34, 26b to chambers 15b, 16b. This initially causes extension of the pistonrod 4b and return of fluid through conduits 25b, 33, 35, and then, when the piston 3b has reached the end of its stroke, piston-rod 9b is extended. Thus, the position shown in Fig. 4 (not shown) is reached. Fig. 5 shows the start of retraction, piston-rod 4e having been retracted by fluid supplied through conduits 32, 33 25e to chamber 14e. When the piston 3e approaches the end of its stroke, a calibrated ball-valve 20e is unseated by a rod 21e. This allows fluid to pass into a chamber 18e through a check-valve so that the rod 9e is retracted. Fig. 6 shows an arrangement in which the rods may be extended simultaneously when the return flow from chamber 14a through conduit 25a a valve 39 and conduit 47 is restricted by a device 38. Because of this restriction, the excess fluid being fed through the conduit 48 is passed into chamber 16a through a duct 27a. If the conduit 46 is closed by valve 39 the rod 9a may be extended on its own.

' A method of pressing a metal sheet to shape comprises placing the sheet between press tools and progressively moving one of the tools into metal forming engagement with the sheet starting at one end of a zone to be pressed and progressing along the zone, wherein one of the tools is formed as a pack of relatively movable laminae in face-to-face engagement, the laminae being moved successively into engagement with the metal by applying pressure to an edge remote from the sheet. An apparatus for carrying out the method comprises a lower tool block 26 having a corrugated working surface 27 and an upper tool block 28 in which are mounted laminae 29, the lower edges of which co-operate to define a working surface when their upper edges are flush with the top of the block 28. The lower block 26 is fitted with rollers 22 which run on a machine bed 1 and along which the toolblocks are pulled by a chain 23 which passes round a guide pulley 24 and a driven pulley 25. The laminae 29 are pressed down sequentially as they pass under a first roller 6 and a second roller 7. The first roller has a small flange at each end, the flanges engaging the top edges of the block 28 and pressing it towards the lower tool block 26 so that the edges of the sheet being pressed are held between the two blocks and prevented from wrinkling. The second roller 7 has a plain cylindrical surface. The top edges of the laminae 29 are angled downwardly at 10 degrees in the direction of travel of the blocks to provide gradual engagement with the rollers. The two rollers are mounted between brackets 5 attached to slide blocks 4 which run on a frame 3. At each side of the frame 3 a chain 15 runs over a guide pulley 10 and a pulley 14 and is dead-ended on the frame. The pulley 14 is mounted on the piston-rod 12 of an hydraulic cylinder 11 which is biased to the extended position. In a modification a flat spring steel plate is interposed between the rollers and the upper edges of the laminae.
