Patent GB-806217-A (GB)
Title: Method of embedding particles in plastic sheet material
Filed: 1956-10-11
Abstract: 806,217. Ornamenting. GOODYEAR TIRE & RUBBER CO. Oct. 11, 1956 [June 25, 1956], No. 30966/56. Class 93 [Also in Group VIII] Ornamented sheet material is produced by forming a sheet of thermoplastic material, pressing particles of thermoplastic material into the said sheet while the particles are harder than the said sheet (e.g. because they are at a lower temperature) to cause the particles to bond to the sheet and displace the sheet material around each particle, heating both sheet and particles and, if desired, one or more backing sheets to a temperature between the softening and melting points of the thermoplastic material, and passing through one to more further presses to iron the particles and the displaced sheet material flush with the surface of the sheet. Suitable sheet materials are polymers or copolymers of vinyl chloride, styrene, ethylene and acrylonitrile. The particles are preferably of the same material as the sheet but may be of another material within the classes set forth above; they preferably have a thickness less, but not much less than that of the sheet. The backing sheets, if employed, may be of e.g. thermoplastic resin, fabric, bitumenimpregnated paper or the like. As shown in Fig. 1, the plastic sheet is formed on heated calender rolls 3, 4, 5 and 6. The particles 11 are fed from hopper 15 on to a travelling belt 13, which may be vibrated, and down shoot 12 into the bight between rolls 9 and 10 and pressed into the sheet between these rolls. The material then passes over cooling drums 21 and 22 and is formed into a roll 24. As shown in Fig. 4, the further pressing and laminating operations are carried out by passing the sheet material from roll 24 through pre-heating ovens 27 and 35 and through continuous presses consisting of internallyheated drums 28 and 37 and endless pressure belts 29 and 38, supported on rolls 30 and 39 respectively so as to encompass a substantial arc of the circumference of each drum. The belt 29 is provided with an adjustable tensioning device 31. The second press is operated at a higher pressure but lower temperature than the first. If desired, backing webs 40 may be led from rolls 41, 42 to be laminated to the ornamental sheet during the hot-pressing operations.

Abstract: 770,919. Glass-making. PILKINGTON BROS., Ltd., and SMITH, R. BARRADELL-, Oct. 24, 1955 [Nov. 3, 1954], No. 31844/54. Class 56  In continuous-ribbon glass-making plant embodying a pair of casting rollers 4, 5 of equal diameter rotating at the same slow angular speed, means such as feelers 16, 17 are provided to detect an outward bend on one roller and an inward bend on the other and to give an indication, as by differently coloured lamps 22, 23 when such bends are detected. The rotation of one of the rollers can then be temporarily advanced or retarted, under manual control, to bring the bends into phase, normal rotation then being resumed. Alternatively the bringing of the bends into phase may be done automatically by means responsive to the signal-initiating means. Although the ribbon will still be somewhat undulating its thickness will be more constant than it is when the bends are out of phase; the undulations will be stretched  out in the subsequent lehr. Fig. 5 shows one form of manual control; in this form the roller 4 is driven from the shaft 6 of roller 5 by the 2:1 gears 7, 8, sun 9 and planets 13, 14 (gearing 25, 24 and sun 11, loose on shaft 12, normally remaining stationary). When signals 22, 23 are given, if they are not in phase the operator closes the appropriate contact 28 or 29 (according to whether signal 22 or 23 is given  first) to energize the motor 27 to give a partial forward or reverse motion to the sun 11 and thereby alter the angular speed of roller 4, this being continued until both signals 22, 23 are given together (indicating that the bends are in phase). One form of automatic means is shown in Fig. 6 and includes, for each roller, stationary field coils 37 in the circuit 20 of the signal associated with that roller. The control also includes for each roller, shaft 33, clutch 34, armature 36 and a magslip transmitter 38, the transmitters 38 associated with roller 4 and 39 associated with roller 5 (not shown in Fig. 6) being connected to a hunter transmitter 40 which signals to the switches 28, 29, Fig. 5 of the motor 27.
