Abstract: 446,354. Television. WILSON, J. C., 24, Whitworth Park Mansions, Moss Lane East, Manchester, and BAIRD TELEVISION, Ltd., 58, Victoria Street, Westminster. Jan. 8, 1935, No. 611. [Class 40 (iii)] Line synchronizing impulses 1, Fig. 1, are alternately positive and negative with respect to a mean level A. At the receiver, the signals after demodulation at 11, Fig. 3, are fed over two channels to a mixing circuit 12. One channel includes a delay device 14 which retards the signals for a period corresponding to one line and reverses their phase, as at B, Fig. 1, so that in the mixing circuit 12, the image signals approximately vanish while the synchronizing signals are additive, C, Fig. 1. These signals are then applied to two valves 15, 16 in push pull, biassed so that each is rendered conducting in turn by the positive and negative impulses to give unidirectional impulses in the output circuit 18. At the transmitter, the impulses are produced by two magnetrons 3, 4, Fig. 2, adjusted so that normally one passes current. The control windings 7, 8, are fed with alternating current so that at a peak, current in one valve is reduced to zero, and at a trough, both valves pass current.

Title: Improvements in or relating to tipping bodies for commercial vehicles
Inventor: MEATS WILLIAM HENRY
IPC: F15B11/08
Filed: 1958-01-08
Abstract: 837,871. Hydraulic apparatus. TELEHOIST Ltd. Dec. 22, 1958 [Jan. 8, 1958], No. 701/58. Class 69 (2). An hydraulic mechanism for tipping the body 2 of a commercial vehicle comprises an hydraulic ram 5 and a flow control valve 17 which is actuated by the tipping movement of the body as the latter is nearing its fully tipped position to cause a pressure rise in the cylinder 5a of the ram whereby the latter is caused to act as a dashpot for the end portion of its travel to clamp the final movement of the body to its fully tipped position. The ends of the ram 5, which is pivoted to the chassis 1 of the vehicle and to a linkage 6, in turn, pivoted to a shaft 7 and to the body 2, are supplied with liquid pressure from a pump 11 alternatively by a manually controlled valve 13. During the tipping operation, the supply from the pump 11 passes to the lower end of the ram and to a pilot valve 8, and from the other end of the ram through the flow control valve 17 which, during the initial movement of the body, has its spool urged to a position by liquid pressure supplied from the pilot valve wherein the wider of two grooves in the spool is coincident with the inlet and outlet ports 26, 27 of the valve to provide an unrestricted flow of liquid from the ram to the valve 13 and a tank 12. When the body has been lifted to approximately its top dead-centre position, a cam 9 on the shaft 7 displaces a spring-urged plunger 10 in the pilot valve 8 to move its spool so as to direct liquid to the opposite end of the spool of the flow-control valve 17 which is thus axially moved so that the narrower of the grooves is coincident with the inlet and outlet ports 26, 27 to restrict the flow of liquid from the ram which now acts as a dashpot during the final movement of the body 2. In an alternative embodiment, the spool of the flow-control valve 17 is moved against a spring during the tipping movement of the body by engagement of a plunger on the spool with -a cam mounted on the mechanical linkage.

Abstract: 1397652 Composite films LA CELLOPHANE 5 Jan 1973 [11 Jan 1972 18 May 1972] 795/73 Heading B5B Apparatus for the production of composite films by co-extruding liquid film-forming compositions through a flat extrusion die comprises a chamber behind the die 1 and a cylindrical feed pipe 2 leading into the chamber in which feed pipe is fitted a flow regulating device comprising a partition 6 mounted on a member 7 so as to be freely rotatable about the axis of the pipe so enabling the angle between the plane of the partition and that of the die to be altered, and hence the angle of the plane of separation of the polymer compositions supplied via channels A and B. Fig. 6A (not shown) shows the partition (6) end-on. According to the orientation given to it, member (7) can be given any position between the two extremes shown in broken lines. Fig. 7 shows a device comprising two partitions 6 and provided with an extra feed channel C and Fig. 8 (not shown) a device with three partitions and two extra feed channels. The apparatus of Fig. 14 utilizes two of the flowregulating devices in series, each being independently rotatable so that each can be oriented both relative to the other and to the lips of the die, and so arranged that the flow from the upstream device may pass either into the middle region or into the side regions of the downstream device. This enables both laminated and juxtaposed films to be obtained, and films which may be laminated and over only part of their width or even not at all. Edge portions of a film may be made of lower grade polymer, or contain recovered waste material. Polymer melts B and C are supplied via side channels 12 and 13 and polymer melt A via a central channel 14 located in rotatable member 15. (For clarity the part of the device above the broken lines has been turned through 90 degrees so that channels 12 and 13 are seen in profile.) Alternatively, four polymer melts may be supplied using a device of the form of Fig. 8 (not shown). Threaded ring 27 connects this device to a similar device consisting of a cylindrical body 28 provided with partitions 19 which can be rotated inside cylindrical body 20, which is attached by threaded ring 24 to feed pipe 21 leading to the extrusion nozzle. A polymer melt D, intended to form the edges of the film, or alternatively two melts D and E, are supplied through side channels 22 and 23, and distribute themselves on either side of the composite melt of the polymers A, B and C.

Title: Improvements relating to the starting of two stroke internal combustion engines
IPC: B60K15/06
Filed: 1954-01-12
Abstract: 739,338. Starting prime movers. BOSCH GES., R. Jan. 12, 1954 [Jan. 15, 1953], No. 825/54. Class 38 (4). In a starting system for a two-stroke internal combustion engine having controlled electric ignition, of the kind wherein starting is effected by oscillatory movement of the crankshaft, produced by automatic reversals of the direction of rotation of an electric starting motor, the arrangement is such that when the engine is turned in a direction opposite to the normal running direction the starting motor is reversed at that instant when the ignition device is actuated, whereby combustion assists ensuing rotation of the starting motor which then turns the engine in the normal running direction. In the arrangement shown, the starting motor 11, having series and shunt field windings 12, 13, is controlled by a main contactor 17 (under the control of the usual starter button 31), a reversing contactor 20, a change-over contactor 18 and an engine driven interrupter 19, which is additional to the usual interrupter 16 for the ignition coil 15. The interrupters are closed over the arcs U19, U16, respectively, as shown in Fig. 2. Assuming the engine at bottom deadcentre UT and the ignition switch 14 closed, closing of the starter button 31 energizes contactors 17 and 18. Contactor 20 does not respond, as its operating winding 28 is disconnected at contact 33 of contactor 18. The motor thereupon cranks the engine in the normal direction (arrow A, Fig. 2), contact 34 of contactor 18 maintaining the ignition coil circuit closed independent of interrupter 16. At point G2 interrupter 19 opens, de-energizing contactor 18, which thereupon closes its contact 33 to energize coil 28 of the reversing contactor 20. The ignition circuit remains closed over interrupter 16. The motor reverses on response of contactor 20, which is subsequently held in by coil 29 when interrupter 19 recloses and reenergizes contactor 18. The engine is thus cranked in the reverse direction until point G1 is reached, when interrupter 19 again opens. As interrupter 16 is also open, ignition now occurs to assist the motor which, through de-energization of contactor 20 consequent upon opening of interrupter 19, now cranks in the forward direction at a speed which should be sufficient to prevent re-operation of contactor 20 until after the point B2 has been reached. Normal ignition then occurs due to opening of interrupter 16 and the engine should become selfrunning, but, if it fails to, the starting cycle is repeated.
