Abstract: 833,259. Filters. STEVENS, R. J. Oct. 28, 1957 [Nov. 6, 1956], No. 33816/56. Class 46. [Also in Group XXVIII] Unfiltered liquid enters the ends of slots E, Fig. 3, exposed near two opposite sides of an "edge" filter consisting of a pack A, Fig. 2, of laminae, the superimposed slots E constituting "inflow lanes" to the filter. Bridges F, Figs. 3 and 4, are provided at intervals across the slots, but are vertically staggered as shown in Fig. 4. The liquid filters between the upper (rough) surfaces of the laminae and the lower (smooth) contiguous surfaces of adjacent laminae and emerges into slots D, Figs..3 and 4, collectively constituting "outflow lanes". These lanes communicate with port openings 8, 11 inporting plates 3, 4 respectively, Fig. 4, which openings provide access to channels 6, 7 and 9, 10 in upper and lower blocks 1, 2 respectively. Outlet pipes 12, Fig. 2, in block 1, and 14 (not shown) in block 2 are provided. Alternatively the normal filtration flow may be the converse of this. The laminae may be cut from a strip such as that shown in Fig. 6, which is etched both to provide the rough area G, Fig. 3, and to provide slots E and D and holes 17 which, on cutting the strip, form locating notches 16, Fig. 3, to co-operate with bolts 5, Fig. 2. To provide the communication of slots E with the space ambient to the pack, two sets of laminae are used, necessitating two strips of material. The strip of Fig. 6, wherein holes 17 are offset to the left, provides laminae of set C, Fig. 3, which extend to the right beyond the edge of the alternate laminae forming set B. Laminae of set B are prepared from strip having the holes 17 offset to the right. The preparation of the strip may be done electrolytically, e.g. by the etching unit of Specification 795,655, or by the process and apparatus of Specification 795,656 [Group XXXVI]. In Fig. 9 (not shown), the bridges F are each as thick as the remainder of the lamina and extend obliquely across the slots, being oppositely inclined in adjacent laminae and being vertically superimposed so as to form, in toto, a column of X's. Thus, where the bridges cross, a load-bearing column is provided, which strengthens the pack.

Title: An improved method for the production of sheets and moulded articles from cork
IPC: B27N3/20
Filed: 1947-12-24
Abstract: In the production of sheets, pipes or other articles of cork by the compression of small pieces of cork with simultaneous heating thereof, the pieces are compressed between pressure plates or mould members that are heated by electric induction from eddy currents therein.  Thus, mould members put together in mating pairs may be piled on top of each other to form a column which is placed in a solenoid or transformer to form the core thereof, the solenoid &c. being fed with A.C. at e.g. 500 to 1000 cycles per second.  By changing the frequency or by phase mutation between current and voltage, the heating effect may be varied. Temperatures of 100-200 DEG C. may be used.  By only partly filling the mould and heating to 200-250 DEG C., porous products may be obtained, the expanded cork filling the mould.  Tubular or tube-segment-shaped articles may be made by using a mandrel in a cylindrical mould, both the mandrel and the mould being heated by electric induction.  Such tubular articles may be sliced into discs to form rings for use in crown cork caps.

IPC: C03B23/217
Filed: 1954-11-25
Abstract: 782,189. Glass manufacture. GENERAL ELECTRIC CO., Ltd. Nov. 21, 1955 [Nov. 25, 1954], No. 34224/54. Class 56. Two parts of a glass envelope, e.g. a cathode ray tube, are relatively positioned, for sealing together, by means associated with two holders 4, 81. The curved end part 13 of a cathode ray tube envelope is held on the holder 4 by vacuum means 6, and the body part 82 of the tube is held by vacuum means on the holder 81 which is rotatable in a support 76 slidable, by screw means 77, along a guide 74, the other end of which carries a fixed support 73 for the holder 4. The holder 4 comprises the plate 4 to which the part 13 is presented, a base plate 1, and a sleeve 2 spacing the plates 1, 4 and enclosing a central pipe which applies the vacuum to a centre aperture in the plate 4. The space between the central pipe and the sleeve 2 is closed by an annulus 6 carried by a metallic bellows on the central pipe. The curved surface of the part 13 is further supported by wedges 14, 15, 16 provided on the plate 4. The work is positional transversely of the holders by four rollers 38 on the ends of arms 30-33 pivoted at 26, 27 and secured to arms which are operated by links 42 connected to pistons 48, 49, and by returning-springs 52. Air pressure is admitted from the pipe 70 to a cylinder 69, a piston therein carrying two pistons 63 which pump oil, each to one of two cylinders 50, 51 containing the pistons 48, 49. Admission of air to the cylinder 69, thus produces an inward swing of all the roller-carrying arms 30-33. In use, the body part 82 is first applied to the vacuum holder 81 and the support 76 is moved towards the holder 4 so that the part 82 is contactible by the rollers 38. The vacuum in the holder 81 is released, and pressure is admitted to the cylinder 69, the consequential movement of the rollers 38 moving the part 82 into its correct transverse position on the holder 81. The vacuum is again applied, the clamp 83 is tightened and the loaded holder 81 is withdrawn from the holder 4 to allow the part 13 to be applied thereto. The part 13 is correspondingly positioned transversely after which the holder 81 is again brought towards the holder 4 to apply the edges of the part 82 to the edges of the part 13. The clamp 83 is then released and the shafts 71, 80 are rotated at the same speed whilst flames are played on the abutting edges to seal them.
