Abstract: <PICT:0588658/III/1> Sheets or plates are made by passing a monomer in liquid or paste form (see Group IV) between parallel moving metal bands 5, 6 passing around drums 1, 2, 3, 4 and polymerizing it by passage through an oven 9.  The monomer is supplied at a spreader 8 and lateral spreading of the liquid or paste is prevented by flexible gaskets 7 of rubber of "Welvic" (R.T.M.) circumscribing the band 6. Specifications 450,305, [Group IV], 491,739, 566,795, [Group IV], 587,191.  [Group V], and 588,660, [Group IV], are referred to.ALSO:<PICT:0588658/IV/1> Sheets or plates are made by passing a liquid or paste containing one or more organic compounds containing the group CH2 = C< between parallel moving surfaces having no relative motion and polymerizing it by the action of heat and/or light with or without the application of pressure.  The liquids include liquid monomers, partially polymerized monomers and solutions of polymers in monomers and the pastes may be mixtures of liquid monomers and solid polymers.  Plasticisers, e.g. tricresyl phosphate and dibutyl phthalate; fillers; reinforcing materials such as fabric; dyes and pigments; heat catalysts, e.g. benzoyl and acetyl peroxides and light catalysts, e.g. benzoin, diacetyl and uranyl acetate and nitrate, may be included.  Monomers specified are methyl, butyl and allyl methacrylates styrene, vinyl acetate, glycol dimethacrylate, dially oxalate and the compounds described in Specification 588,660. The moving surfaces may be of steel or regenerated cellulose. Cationic wetting agents may be applied thereto to facilitate stripping.  Heating may be effected by passing the moving surfaces through a steam- or electrically-heated chamber, between banks of radiant heaters, heated rollers, heated track elements or by using the surfaces as spring-loaded rollers or electrodes for high-frequency heating as described in Specification 587,191, [Group V].  Pressure may be applied to the surfaces by passing them between metal bands to which pressure is applied by track elements having flat faces. Decorative effects may be produced on the sheets by using moving surfaces corrugated or engraved or coated with a pattern, e.g. of polythene.  Textiles or paper bearing printed designs may be run into the nip of the bands simultaneously with the monomer so that they are embedded in the polymer.  Relief images may be formed by the process described in Specification 566,795.  As shown, continuous metal bands 5, 6 pass around wide drums 1, 2, 3, 4. An oven 9 encloses a portion of the moving bands and the polymerizable material is supplied at a spreader 8.  Flexible compressible gaskets 7 of rubber or "Welvic" (Registered Trade Mark) circumscribe the edges of the band 6 to prohibit lateral spreading of the liquid or paste.  The product may be used for bathroom tiles and roof lights. Specifications 450,305 and 491,739 also are referred to.

Title: Improvements in or relating to telegraphic receiving apparatus
IPC: H04L13/04
Filed: 1926-09-03
Abstract: 284,740. Creed & Co., Ltd., and Salmon, R. D. Sept. 3, 1926. Type-printing telegraphs.-In a motor-driven telegraphic receiver the motor and a driving shaft of the apparatus are started automatically by the receiving relay on receipt of a starting signal, continue to run during the receipt of subsequent signals, and are stopped automatically when signalling has ceased for a predetermined time, the relay being inoperative on the motor-starting means after the receipt of the starting signal. Fig. 1 shows the application to the type-printing receiver described in Specification 228,842. The circuit of the driving motor 13, Fig. 4, includes switch contacts 1<b>, 2<b> carried respectively on the U-shaped end of a pivoted arm 1 controlled by a spring 4 and on a pivoted arm 2 controlled by a spring 5, and a stop 6 between the limbs of the U limits the movement of the arm 1. The spring 5 connects the arm 2 to a third: pivoted arm 7 and normally holds the switch open with the arm 7 above the free end of the arm 2 until the latter is acted upon by a crank member 8 carried by a spindle 9 axially movable in a bearing 9<a1>, Fig. 5. A collar 9<a> on the spindle is engaged by a fork 18 for moving it axially against the action of a spring 13, and springs 11, 12 acting on a block 10 secured to the spindle tend to rotate it in a direction to cause the member 8 to close the switch. The spindle passes through the centre of a disc 14, provided with diametrically opposed holes 14<a> and rotated slowly through worm gearing from a shaft 17, Fig. 1, driven by the motor B. With the motor at rest and the end 8<a> of the crank member 8 in engagement with one of the holes 14<a>, the receipt of the first signal by the relay 22 causes the relay tongue 21 to actuate, through a link 21<a>, a bellcrank 20, 20<a> of which the arm 20<a> acts on the block 10 to slide the spindle 9 against the action of the spring 13, thus disengaging the end 8<a> from the hole 14<a> and allowing the springs 11, 12 to rotate the spindle for closing the motor circuit. The arm 7 thereupon snaps into position to lock the arm 2 in switch-closing position, and a notch 10<a>, Fig. 5, in the block 10 is brought opposite the arm 20<a> leaving the end 8<a> free to re-engage one of the holes 14<a>. The disc 14 is now rotated slowly, moving the member 8 towards the arm 7. As long as signals are being received the fork 18 is operated periodically to slide the spindle 9 for disengaging the end 8<a> from the hole 14<a>, this operation being effected from a cam c, Fig. 1, driven from the motor B under control of the signals, and occurring before the member 8 reaches the arm 7. When, however, the signals cease, the fork 18 is no longer operated and, after a predetermined time, the member 8 acts on the arm 7 to allow the switch to open thus stopping the motor. The invention is also applicable to the type-printing receiver described in Specification 285,100.

Title: Improvements in machines for stranding wires
Inventor: GRIEVE GEORGE THOMAS WILSON
IPC: D07B7/16
Filed: 1954-07-26
Abstract: 791,592. Machines for making wire strands. BRITISH INSULATED CALLENDER'S CABLES, Ltd. July 26, 1955 [July 26, 1954], No. 21797/54. Class 109. A wire stranding machine in which bobbins are supported between pairs of parallel rotatable discs has each bobbin supported on stub axles mounted in the discs, one axle of each pair being retractable to the accompaniment of an endwise movement of the bobbin sufficient to free it from the other stub axle. Stub axles 8, 10 are carried in ball bearings in bushes carried in discs 1. Axle 10 is mounted in a sleeve 13 slidable in a bush 15 when a pin 19, normally held in a depression 20 by a spring 21, is freed. To facilitate movement of the sleeve 13 there is attached to it a plate 17 with a projection 18 that may be seized by a withdrawing head 22 actuated at appropriate times by a pneumatic cylinder 31 to which it is connected by a piston rod 23. Located on the head are catches 32 which are normally pressed inwards by springs 33 but which may be moved outwardly by movement of a rod 47 that is connected to the catches 32 through a Bowden cable 57. The rod 47 may be operated by lever mechanism. The steps of unloading empty bobbins and reloading with full bobbins may be effected manually, but some steps may be automatically controlled by providing a disc 1 with a cam 90 for each bobbin. As each cam presses a button 91, air is admitted to the end of the cylinder 31 so that the head 22 is thrust forward and then immediately withdrawn. The catches 32 are in operative positions to seize the projection 18 during unloading and in inoperative positions during loading. Throughout the unloading and loading operations, the discs 1 revolve slowly and cross-tubes between them roll bobbins along the floor into and out of the doffing position. Electrically controlled catdhes hold back full bobbins from rolling into loading position until they are required. To avoid accidental movement of the stub axles 10 when the machine is stranding, a guard ring 102 is provided. This ring 102 contains a safety switch for operation by a misplaced projection 18 to open the main power circuit of the machine.
