Patent GB-1403251-A (GB)
Title: Communication system
IPC: H02J13/00
Filed: 1972-07-24
Abstract: 1403251 Digital transmission over power lines; party line systems CENTURY INTERNATIONAL CO Ltd 24 July 1972 34547/72 Headings H4P and H4R Grouped message stations are connected to a hierarchical network in the form of a pyramid, which may be an electric power distribution system, messages being routed by means of an address defining the series of control stations through which a message must pass in order to reach its destination. Messages destined for a message station connected to the same control station pass directly, but other messages are temporarily stored at a control station until polled by a higher control station. Each control station A1 contains an interrogating transmitter 12 which polls lower stations in turn by means of addresses stored at 16. Each control station, as well as message stations, also contains an interrogation receiver 18. When the appropriate address is received a circuit 20 ml opens gate 24 ml allowing messages in store 26 to flow through transmitter 28 ml into receiver 30 cl in control station A1 and parallel stations. Interrogation and message frequencies are different. At each interrogation circuit at control stations, received addresses are compared; if the control station is not to accept a message for retransmission a gate 36 1  is blocked. However if the message is for retransmission to a higher level, gate 36 1  is opened permitting passage to store 38. If store 38 becomes full or after each lower station has been polled, further polls are inhibited and gate 173 is opened allowing any messages in 44 received from station B1 to pass through transmitter 28 cl. Data flow to lower and higher stations are substantially independent of each other and may take place simultaneously. When used in conjunction with an electric power system, distribution transformers may be by-passed by a repeater as shown in Fig. 9. Signals f3, f 4  in one direction may be collected by transformer winding 203 and passed by series resonant circuits 210, 211 through amplifiers 214, 215, another pair of resonant circuits 212, 213 and another winding 201 to the outgoing line. A non-physical gap 216, 217 comprising a radio, optical, or acoustic link must be provided for electrical isolation. For providing amplification along an unbroken line, in a three phase system (see Fig. 1a, not shown) signals collected from one line may be retransmitted on another line to avoid interference. Alternatively in a single phase system where cyclic transposition is not possible, the frequency ranges may be changed at successive amplification points to avoid interference through feedback (see Fig. 11b, not shown).

Title: Method and apparatus for continuously curing plastic material
IPC: B32B27/00
Filed: 1958-10-29
Abstract: Natural or synthetic rubber sheeting or the like is cured, polyvinyl chloride or other thermoplastic materials are fused and subsequently set, and belting or other laminates of the above materials alone or in combination with fabrics are made in continuous lengths, by compressing the materials between a pair of steel or other heat-conducting bands which pass in succession around a first drum, in the opposite direction around a second drum, and finally along a straight path during which the bands may be pressed together.  As shown, constituents S, S, of a laminate, either separate or pre-assembled, are passed around drums A, B, and then along a straight path P, between endless steel bands X, Y.  The band X is returned via pulleys E, D, and the band Y via pulleys F, C, the pulleys E, F, being mounted on levers 19, 24 connected to hydraulic cylinders 22, 28 for tensioning the bands. The pulley C is slidably movable by screw means 18 to apply adjustable pressure at the entrance to the drum A, and the pulley F is movable, by an hydraulic cylinder 31 and a slide 30 lockable by nuts 32, to adjust the straight reach of the band Y towards and away from the band X.  In this reach hydraulically operated rolls 36 co-operate with fixed rolls 34 to apply to the bands and the enclosed laminate a pressure which is less than that applied by the drums A, B.  For heat-curing rubber materials or laminates containing them steam &c. is introduced into both drums through inlets 39, 41 and <PICT:0865832/IV (a)/1> radiant heat units U are provided around them and along the straight path P.  For fusing and subsequently cooling thermoplastic materials drum B may be internally cooled and air blowers, refrigerating pipes or other cooling means may be provided in place of the units U around and beyond this drum.  The emerging material is wound up at W.

Title: Improvements relating to means for synchronising cinematograph and sound-reproducingapparatus
IPC: G03B31/00
Filed: 1928-12-01
Abstract: 325,882. Hepworth, C. M. Dec. 1, 1928. Addition to 324,005. Sound-reproducing apparatus associated with kinematographs. -A synchronizing device as claimed in the parent Specification is provided with a stop or a pair of stops to prevent the brush from leaving the contacts (this provision being necessary when the contacts are arranged in the form of an arc) and with a yielding coupling in the transmission from either of the machines to the brush or to the contacts. The coupling is such that it transmits, without yielding, the necessary torque during normal working of the apparatus, but yields and prevents the transmission of excessive torque when the brush bears against one of the stops. In the construction shown, resistances 6 in the, circuit of the motor 3 driving the picture projector 1 are connected to contacts 8 mounted on a quadrant 9 on a shaft 4 rotating with the projector. An arm 11 which carries the brush 10 for engaging with the contacts, and which is rotated bv a shaft 5 driven from the gramophone 2, is prevented by stops 13 from moving in either direction beyond the end contact studs 8. The shaft 5 is divided into two parts 15, 16, Fig. 3, which are coupled by a device comprising a disc 17, from opposite faces of which project screwed stems 18, 19 having right- and lefthanded threads, respectively. These stems screw into sleeves 20, 21, the sleeve 21 being fixed to the shaft portion 15, whilst the sleeve 20 has a squared recess in which the squared end of the portion 16 slidably engages. Light springs 22. 23 normally maintain the sleeves 20, 21 screwed up against the faces of the disc 17. With this arrangement, during normal synchronous running of the two machines, the arm 11 remains in the position shown in Fig. 2, but if the kinematograph lags or leads with respect to the gramophone, sufficiently for the arm 11 to be brought up against one of the stops 13, one of the springs 22, 23 will be wound up. At the same time, relative movement between one of the sleeves 20, 21 and the corresponding stem 18, 19 will occur. This yielding action of the coupling continues so long as one of the machines tends to over-run the other, and the coupling returns automatically to its normal position. when the speeds of the machines have been equalized. In a modification, the resistances 6 are stationary. instead of being mounted on the shaft 4. and are wired to slip rings on the shaft, these rings being connected to the contacts 8.

Title: Improvements in or relating to fire protective devices for kinematograph apparatus
IPC: G03B21/18
Filed: 1930-12-02
Abstract: 352,880. Kinematograph apparatus. ZEISS IKON AKT.-GES., 72, Schandauer- .strasse, Dresden, Germany. Dec. 2, 1930, No. 36353. Convention date, April 4. [Class 97 (i).] Kinematograph apparatus has two fire protective channels of different widths to accommodate films of different widths, and means are preferably provided for the prevention of erroneous insertion of a narrower film into the wider channel. As shown in Fig. 1, a fire trap secured to a spool box consists of a main portion 1 having a track 2 for normal films and a track 3 for broad films. The roller 4 has enlarged portions 5, 6 for guiding normal and broad films respectively. Hinged on the two sides of the portion 1 are doors 7, 8 which carry pressure rollers fitting on the portions 5, 6 of the roller 4 respectively. The hinge pin 17 for the door 8 carries a plate 18 at its lower end on which is a pin 19 adapted to fit into a hole 20 in the main portion 1. The hinge pin 17 is caused to rotate with the door 8 by pins 15, 16. A pivoted lever 21 is mounted in the spool box, one arm 22 being pressed by a spring against the side 23 or 24 of the spool. The other arm 25 bears against an inclined plane 26 on the top of the hinge pin 17. If a broad spool is in the spool box tha side 23 presses against the arm 22 of the lever 21, and the arm 25 is so moved thereby that it presses on the inclined plane 26 and forces the hinge pin 17 downwards against the spring 27 so that the pin 19 does not engage with the hole 20, and the door 8 can be opened. If a normal spool is in the box the arm 25 moves away from the inclined plane 26 and the hinge pin 17 is free to move upwards against the action of the spring 27, thereby forcing the pin 19 into the hole 20 and locking the door 8.
