Title: Selective signalling system
IPC: H04B10/10
Filed: 1967-03-03
Abstract: In a signalling system including a transmitting station and a receiving station, the transmitting station includes an encoder capable of transmitting selected codes of a plurality of characteristic calling codes and each receiving station includes a decoder responsive to a selected one of the characteristic calling codes, each calling code comprising a sequence of characters and each character comprising a sequence of pulses. In the embodiment described data is entered into an encoder at the transmitter by means of a keyboard 70 (Fig. 2A) and stored in a shift register 72 comprising a series of bi-stable stages which store a four digit character in a two out of five code. Under the control of an output driver 73 the data in the register 72 is gated serially to a translating device 75 which includes a relay having two coils W1, W2 connected to be alternately operated by a contact c1. Whenever an output pulse from a set stage of the register 72 is received contact c1 switches its position to either energize or de-energize coil W2 and so open or close contact c2 to control the connection of a battery B1 to the transmitter 74. In this way a serial pulse train is fed from the translator 75 to a transmitter 74 where if required and if for example the transmission is by radio link a single frequency tone may be transmitted when a pulse is received by the transmitter 74 with absence of tone when there is no pulse or alternately one frequency may represent a pulse and a second frequency no pulse. In this case suitable filtering means are required at the receiver. A land line transmitter or an optical transmitter may be used, in the latter case the pulses being used to modulate a transducer capable of biasing for example a laser. At the receiver the complement L of the received pulse train L is also generated and the two pulse trains fed to multi-aperture cores 110 (Fig. 8) having selected windings N c and N s linking the cores through major apertures and windings N x linking all the cores through the minor apertures. The N c windings are selectively connected to the leads 114, 115 on which the two pulse trains are received so that when a receiving station receives its characteristic calling code the first core 01 r is switched to its set state by an initial tag bit and the state of this core is transferred to the next core by each successive bit on the leads 114, 115 so that at the end of the four character code an output signal may be received on output loop 116 of the last core 20 r to illuminate a lamp. To facilitate altering the windings of the cores 110 so that the characteristic code of a receiver may be altered the windings may be connected to a plug board assembly (Figs. 11 and 12, not shown).

Title: Regulated power supply
IPC: H04N3/185
Filed: 1967-05-20
Abstract: In a line deflection circuit for a television receiver, the grid of a shunt regulating tube 90 for the E.H.T. supply is supplied by the voltage developed across an impedance 80 . . . 84 traversed by the beam current, and auxiliary winding RM of the line deflection transformer being interposed between the impedance and the E.H.T. winding PM so as to isolate the impedance 80. . . 84 from the high pulse potentials. As described, the line output stage 55 is coupled to deflection coils H, H1 by means of transformer 60, of specified construction (see Division H1). The E.H.T. supply for the cathode ray tube 20 of a colour television receiver is derived by rectifying the flyback pulses in the high voltage winding PM and is stabilized by tube 90 shunted across the transformer 60. The flyback pulses at tapping D are differentiated at 101, 103, 105 and fed to the screen of the tube 90 and further differentiated by the self capacitance C and resistor 86 before being fed to the grid. This ensures that the tube 90 is conductive only during the leading edge of each flyback pulse, the current in the tube being controlled by the voltage developed by the beam current flowing in impedance 80. . . 84 so as to compensate for changes in beam current. A convergence winding 61 is included. Damping diode 62 and linearity adjustment 70 are provided. Components 63, 64, 65, 66 minimize radiation. An anti-hunt capacitor 85 is included.

Title: Resin coated sheet material
IPC: D04H1/488
Filed: 1967-06-16
Abstract: Sheet material having beads or globules of thermoplastic resin adhering to one surface in spaced relationship in a controlled pattern is produced by feeding a base sheet between a roller and a straight bar carrying a row of spaced apart needles, which needles project from the bar towards the roller, supplying the surface of the roller with a coating of a thermoplastic resin composition, reciprocating the bar so that the needles repeatedly penetrate the base sheet without any substantial relative movement between the needles and the sheet in the direction of travel of the latter, whereby the needle points after each penetration of the sheet pick-up resin composition from the roller and on withdrawal through the support sheet leave a row of spaced apart beads or globules of resin composition adhering to a surface of the sheet, and then passing the treated sheet through a drying chamber to gel or cure the resin. The material may be used as a fusible interlining. The needle carrying bar may also be oscillated in a direction transverse to the path of travel of the sheet material whereby the beads or globules left adhering in one row on the support sheet are staggered in relation to the beads or globules adhering to the sheet in the next adjacent row. The base sheet may be woven, of slack open weave or dense close weave, knitted, a non-woven tissue or foamed plastic material. The thermoplastic resin composition may be based on polyvinyl chloride or co-polymers of vinyl chloride with vinyl acetate incorporating a plasticiser. In Fig. 1 sheet material 10 passes between a straight bar 16 carrying a row of needles 17 and a resinapplying roll 18 provided with doctor 19, and then passes through a drying chamber 21. Reciprocal motion is imparted to the needle carrying bar 16 by connection to rods 24 of a self-aligning eccentric 25, the rods sliding in a fulcrum 26. The needle carrying bar is also oscillated in a direction transverse to the path of travel of material 10 by means of a pressure-operated piston and cylinder device, the piston being connected to the end of the bar 16. Driving means for the rolls and parts of mechanism of the apparatus are illustrated in Figs. 2, 3 and 4 (not shown). The sheet material having the applied beads or globules of the thermoplastic resin adhering to one surface thereof can be securely bonded to other sheet material by the application of heat and pressure. By using a brightly coloured resin paste, material having a sequinned appearance may be produced.
