Abstract: 1,168,463. Elastic-covered toy. R. LANG. 1 Nov., 1966 [1 Nov., 1965], No. 48950/66. Heading A6S. A toy, having an elastic covering stretched on a rigid shell comprising an assembly of moulded pieces, is made by successively inserting the pieces in the covering, which is slightly smaller than the shell and so grips it elastically, and closing the covering over the shell pieces, which may or may not be partly assembled before they are inserted in the covering. The shell may be of moulded plastics and the covering present the external aspect of plush. A particular embodiment is an animal with four legs, whose shell comprises three pieces: a body and head, a pair of fore legs, and a pair of hind legs; each pair of legs being provided with a housing adapted to fit into a complementary housing in the body, and held in position with a screw. In this case one pair of legs is first attached to the body, both pairs of legs are then inserted separately into the covering, the other pair of legs is attached to the body, and the body and head are finally covered with the covering. The process of Specification 1,151,591 is disclaimed.

Filed: 1970-10-29
Abstract: 1306467 Multiplex radio signalling INTERNATIONAL STANDARD ELECTRIC CORP 29 Oct 1970 [5 Nov 1969] 51381/70 Heading H4L In a television transmission system of the type in which one or more sound signals are transmitted in time division multiplex with the vision signal, the transmitter includes a storage device to store during each frame period samples of the audio signals occurring during that frame period and is arranged to transmit the stored signals between the end of each frame and the start of the next frame. As shown in Fig. 2, two different audio signals are supplied via terminals 3, 4 respectively to storage devices 6, 7 and the associated video signal is supplied to terminal 5. A control signal generator 26 is synchronized by the colour subcarrier signal and provides low and high frequency control signals on terminals 11, 12 respectively. The audio signals are stored under the control of the low frequency signals and read out under the control of the high frequency signals via a distributer 8 to the modulator input of the transmitter. Switches 8, 9, 10 are operated by control circuits synchronized by the line syncsignals so that the two signals are read out during different line periods of the frame flyback period. At the receiver, Fig. 3, the video signals are amplified and supplied to a cathode ray tube 16 and the audio signals tranmitted in the frame flyback period are supplied via switch 25 to a store 17. The signals are stored under the control of a high frequency signal from terminal 12 and read out by a low speed signal from terminal 11 via switch 18 to operate a loudspeaker 24, switches 18 and 25 being operated together so that when switch 25 is closed switch 18 is connected to terminal 12. A counter 19 receives frame sync. pulses via terminal 20 and line sync. pulses via terminal 21. The frame pulses reset the counter 18 to zero which then counts line sync. pulses until a number corresponding to the first audio modulated line period is reached at terminal c and switch 25 is closed. A pulse at terminal d corresponds to the second audio signal and terminals c, f relate to two other audio signals which are used when receiving other transmitters. One of the two audio signals may be the sum signal and the other the difference signal of a stereophonic system or the signals may be in different languages. The storage device may be of the "bucket-brigade" type or magnetic recording may be used.

Abstract: 1366698 Cooling engines M BEHR [trading as SUDDEUTSCHE KUHLERFABRIK JULIUS FR. BEHR] 4 Nov 1971 [17 Nov 1970] 51401/71 Heading B7H A diesel-electric locomotive having a cooling system for an I.C. traction engine provided with electrical braking resistors and cooling means for the resistors which are adapted to operate when the engine switches from traction to braking operation, the system including hydraulic circuits for a first fan motor in a main cooling circuit and for a second fan motor in a secondary cooling circuit, wherein means are provided for stopping the second motor and increasing the speed of the first motor on switching from traction to braking. The circuitry includes a change-over valve 10 having a master piston 18 controlling a connection between lines 20 and 22, and a servovalve 23. Line 20 communicates with the servovalve via a bore 38 in the piston 18 and a cone valve member 26 seated by a spring 27 loaded by a servo-piston 24. First motor 1 has a back pressure line 29 including a throttle 28 which leads to an end face of the servo-piston and to a return line 30 which includes a solenoid valve 9. During traction valve 9 is open and fluid is supplied by pump 3 to motor 1 and via lines 21 and 22 to the second motor 2. The braking resistor shutter adjusters 8 are closed and pressure is supplied by a flow regulating valve to the main and secondary shutter adjusters 6 and 7. On switching to braking, valve 9 is closed and piston 18 is moved to shut the connection between lines 20 and 22 thus stopping motor 2. Bore 38 allows fluid to pass to line 22<SP>1</SP> to operate the adjusters 8 and a line from line 22<SP>1</SP> supplies fluid to the main circuit adjuster 6. Stopping the second motor allows greater fluid flow to the first motor thus causing it to increase speed. In a second embodiment, Fig. 2, pump 3 supplies fluid to the second motor during traction via annular grooves 40, 39 in a change-over valve, communication between the grooves being controlled by a piston 33. The piston is moved to connect the grooves against the action of a spring 37 by fluid supplied via a bore 42 to a chamber 48. A throttled back pressure line from motor 1 is connected to both end faces of the piston by lines A<SP>1</SP> and 29, line 29 being exhausted by line 30 through soleoid valve 9 during traction. On closing valve 9 for braking pressure builds up to move the piston 33 and sever the groove connection thus stopping the second motor.
