Title: Improvements in or relating to the production of hollow laminated tubes
Inventor: EVANS EDWARD MICHAEL
IPC: B29C41/22
Filed: 1954-09-11
Abstract: A preformed tube of sheet material impregnated with thermosetting resin is inserted in a cylinder and the resin is cured while the cylinder is rotated at a speed sufficient to produce a centrifugal pressure at its inner surface of at least 1/4 ton per square inch. The sheet material may be paper or textile fabrics of synthetic or natural fibre including glass fibre.  The resin may be phenoplast or aminoplast, e.g. the products of condensation of commercial cresol mixtures with formaldehyde in the presence of aqueous ammonia solution, or urea and melamine formaldehyde condensates.  A strip of paper may be impregnated by passing it through an alcoholic solution of the resin and then through a heated tunnel to drive off the solvent and, if desired, to effect slight precuring.  A resin-impregnated paper strip may be inserted in the cylinder as a loose roll which is then formed as a tube by rotating the cylinder. The resin may be cured by infra-red ray heating or electrical inductive heating by eddy currents in the cylinder walls.  The rotating member may be shaped to produce tapered tubes.

Patent GB-268822-A (GB)
Abstract: 268,822. General Railway Signal Co. (Assignees of Wight, S. N.). Aug. 6, 1925, [Convention date]. Drawings to Specification. Electrical systems, non-automatic. - In an absolute-permissive block system of train control of the general type described in Specification 11804/14 modified as described in Specification 256,642 means are provided for the combined automatic and manual control from a remote point of railway switch-points and the associated signals. Manual means at the control office control a relay by which a switch-points machine is brought into operation and corresponding signals set, the machine and the signals being interlocked to prevent operation of the switch-points if the traffic conditions are adverse. Operation of the switch points is prevented when a train is approaching under favourable traffic conditions. If, however, a train enters the approach section when signals are against it, an alternative circuit is closed which permits operation of the switchpoints. This alternative circuit is completed by a control relay having a time lag so as to give a short period of time in which signal information can be set for the train or the train will have cleared the points. Additional relays are provided by means of which the presence of a train in a fouling section does not prevent the operation of the switch-points machine if the train is moving away from the points. The actuation of the switch-points and the passage of trains into and out of fouling sections is indicated in the control office by bell signals substantially as described in Specification 256,642. The switchpoints machine may be, as described in Specification 169,795, capable of reversal at mid stroke.

Abstract: 331,752. Grossenhainer Webstuhlund Maschinen-Fabrik Akt.-Ges. April 15, 1929, [Convention date]. Stop-motions, weft.- In centre weft-fork stopmotion devices, the movement of the bunter into operative or inoperative position is effected at open-shed position by link and lever mechanism operated solely by the driving-shaft of the loom and under control of the centre weft-fork. In the form shown in Fig. 1, a rod 15 reciprocated vertically by give-way mechanism 10 - - 14 from a cam 3 on the driving shaft 1 is connected to a bell-crank lever connected by a rod to the usual slide of the centre weft-fork 24. A second rod connected to the slide is connected to a lever pivoted at 28 and carrying the bunter 29 which is normally moved out of the path of a lever 30 controlling the stopping- rod of the loom. When weft is absent, the slide is stopped by the weft-fork and the bunter is not moved clear of the lever 30, so that the loom is stopped in the open-shed position. In the form shown in Figs. 4 and 5, the rod 15 is connected to a three-armed lever 16 which is connected to a rod 20 for operating the slide 23 of the centre weft-fork 24 and through link and lever devices 41 - - 47 to a bunter 29 pivoted to the lever 47 and to an arm 51 controlled by a swinging link 53 having a roller 54 adapted to engage a cam 58 on the driving-shaft 1. When weft is present, the movement of the slide 23 causes the bunter 29 to be raised clear of the lever 61. When weft is absent, the slide 23 is locked, and the bunter 29 remains in the position shown in dotted lines, so that it is moved by the cam 58 to engage the lever 61 to stop the loom.

Abstract: 1,116,264. Rollers. KIMBERLY-CLARK CORPORATION. 28 June, 1965, No. 27320/65. Heading F2U. A steam-heated drying drum has condensate removal nozzles 39-54 uniformly distributed over the inner surface of the drum and connected to conduits 59-65 which remove water from the drum through a bore 36 in a trunnion 35. The nozzles rotate with the drum and serve to maintain a substantially uniform layer of condensate of minimum thickness at high drum speeds when the condensate rims the interior surface of the drum. Steam is admitted through a bore 37 in a trunnion 34 and thence through holes 38 to the interior of the drum. Each nozzle is relatively long and narrow and has a single long narrow opening or three such openings extending in a radial plane of the drum. In a modification each nozzle has three circular openings disposed in a radial plane. A scoop may be provided to remove condensate collecting in the lower part of the drum when it is driven at slow speed.
