Patent GB-1428401-A (GB)
Title: Board- or paper-making process and machine
IPC: D21F11/04
Filed: 1972-02-23
Abstract: 1428401 Papermaking WALMSLEYS (BURY) Ltd 23 Feb 1973 [23 Feb 1972] 8255/72 Heading D2A To manufacture a paper or board of two or more plies, a first comparatively dry ply is formed on a unit 14 and then caused to undergo a change in direction of greater than 90‹ at B, e.g. at a roll 28, and immediately thereafter applied to a second comparatively wet ply formed on a unit 10 as the second ply travels in a straight path, water then being drawn from the wet ply to the dry ply, e.g. by suction box combination 56a-56c, to bond the plies together. As shown in Fig. 1 the first ply may be a composite ply formed by the union at A of a comparatively wet ply from the unit 14 and a comparatively dry ply from a unit 12, the plies from units 12, 14 being bonded together in an analogous way to the bonding of the plies at B. In a modification, as in Fig. 3, four forming units 10, 12, 14, 60 are positioned one above the next, each supplying a comparatively dry ply to be united with a comparatively wet ply formed on the underlying unit.

Title: Improvements in making ready cylindrical printing plates
Inventor: REILLY FRANK EUGENE
IPC: B41M9/02
Filed: 1951-04-14
Abstract: 715,030. Printing-surfaces; printing processes. ELECTROGRAPHIC CORPORATION. April 14, 1951, No. 8346/51. Class 100 (2) Mechanical treatment of plates; make-ready arrangements. - An underlay for making ready a cylindrically curved relief printing plate is prepared by forming a stereotype mat from a printing plate or forme and a flong which shrinks on drying in a direction circumferentially of the cylindrical plate to be underlaid, drying the mat and forming from the mat itself or by means of the mat an underlay having thicker portions corresponding to the solid printing areas of the plate. The mat used in preparing the underlay, Fig. 2, has on its back raised portions 22, 24, corresponding to the full tones and half tones of the printing plate or forme. The required underlay is formed therefrom either (i) by shaving away the front of the mat after shrinking and using the shaved mat itself as an underlay or (ii) by casting from the shrunk mat a stereotype plate, printing with the latter on a sheet of underlay stock and cutting the printed sheet of underlay stock to form an underlay in accordance with the printed impression thereon. The underlays so formed may be used directly as a press underlay or may be used in the bumping of the cylindrically curved press plate which is subsequently used without the underlay. As shown in Fig. 6 a plate 60 is passed, together with the underlay 36 and a reverse overlay 50, between pressure rollers 62, the printing surfaces of the plate being forced to the required height. The underlay 36 may have been made either as in (i) or (ii) above. Specification 701,752 is referred to.

Title: An improved combined universal and sliding joint
IPC: F16D3/06
Filed: 1958-03-17
Abstract: 861,088. Universal joints. MORGAN, H. R. June 12, 1959 [March 17, 1958], No. 8410/58. Class 80 (2). [Also in Group XXXIV] A universal joint of the Hooke's type having a central cross-shaped spider pivoted to two shafts has also bearing means between the spider and one of the two connected shafts to permit relative axial movement. In one form, a shaft 1, Figs. 1, 2, 3, carries at its end a fork 2 within which are pivoted by needle roller bearings 3 two trunnions 4A of a central crossshaped spider 4 having another pair of trunnions 5 at right-angles thereto journalled by needle roller bearings 6 in slipper blocks 7 which are enabled to slide axially relatively to a surrounding housing 9, fast with a shaft 13, by roller bearings 10 disposed between the slipper blocks and race-ways 8B in channels formed in the housing. Under load, the rollers 10 at one side only of each slipper block 7 transmit torque between the shafts 1, 13, so that the rollers on the other side are relatively free, the rollers re-circulating during relative axial movement of the shafts and being retained in position by guides 11 at the ends of the races 8B. The housing 9 is closed by a bellows 15 which may be of aluminium. In the form shown, a double row of rollers 10 is used. In one modification, Figs. 4 ... 7 (not shown), two rows of rollers are again used, but are separated by a central ridge on the slipper blocks 7 and engage inside channel-shaped races inserted into the housing, which is made from two equal parts welded together along axial lines. In another form, a single row 10, Fig. 9, of barrel-shaped rollers 10 lies between each side of the slipper blocks 7 and the housing 9A, which has channels of frusto-cylindrical cross-section co-operating therewith. The housing 9A is made from two equal parts welded together along axial lines 18. Alternatively, Fig. 10 (not shown), the weld connections may be along the outermost portions of the blockreceiving channels. As a further modification, balls may be used instead of rollers.

Abstract: 936,508. Turbine and compressor blades. ROLLS-ROYCE Ltd. March 12, 1962 [March 13, 1961], No. 9176/61. Class 110 (3). An inlet or nozzle guide vane or compressor or turbine stator blade member, has an internal chamber in which resilient means make an interference fit with and exert an outward pressure on the walls of the member. The vane has an outer wall 10, Fig. 3, enclosing a chamber containing support tubes 11, 12, heating or cooling air supply tube 13 and coil springs 15, 16 which make an interference fit with the walls. Prior to insertion in the vane, each spring is twisted to reduce its coil diameter by mounting on a mandrel 18 carried by a chuck 19, gripping one end of the spring and rotating the chuck. The free end of the spring is then clamped, mandrel 18 removed from the chuck 19 and inserted with the spring into the vane. The clamping device is released to allow the spring to untwist and press against the walls of the vane 10. A top cover seals the chamber. Alternatively, the coil diameter of the spring can be reduced by stretching and locking it in the stretched state on the mandrel 18. The spring may be embedded in a moulded silicone rubber strip before stretching on the mandrel, and the external surfaces of the strip coated with silicone grease or adhesive before inserting into the vane and unlocking on the mandrel. Any part of the mandrel projecting out of the vane may be cut off, or the mandrel may be removed and the space in the spring filled with silicone rubber which is foamed by heat treatment to effect vibration damping.
