Abstract: 495,984. Viewing-apparatus. BUCKINGHAM, J. F. June 28, 1937, Nos. 17909 and 34809. [Classes 97 (i) and 98 (ii)] Apparatus for viewing a coloured film by artificial light includes a hollow box-like support with an upwardly-inclined wall 13 having an opening over which the film is mounted, a lower horizontal wall 11 with a diffusing reflector 17 and means for carrying an electric lamp beneath an upper part of the inclined wall 13 so that light can not pass directly from lamp to film but only from the reflector to the film. The inclined wall 13 is mounted on the base 11 by triangular side pieces 14 and the coloured film is supported over the square opening by two lugs 15 or, in the case of a rectangular film to be viewed in the upright position, by a central lug 16. The reflector 17 (shown partly withdrawn in Fig. 1) has an upper surface adapted to diffuse light and is slidable on the base, being held in operative position by a catch 25. The electric lamp 20 is mounted under a plate 23 with side screens 22. In use the plate 23 is placed in guides 30 of wall 13. When not in use, the plate is reversed and held in the device by the pin 26 of catch 25, as shown in Fig. 2, the sides of the plate resting on ledges 24. In use the light is unable to reach the colour film directly but is first diffused and reflected by the diffusing reflector 17. The latter, if a daylight type of electric lamp is used, may be a reflector with a frosted glass surface. For a non-daylight lamp a tinting means is included as set out in Specification 496,010.

Title: Improvements in and relating to arrangements for carrier modulation
IPC: H03C1/08
Filed: 1943-11-03
Abstract: 567,517. Modulating systems. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 3, 1943, No. 18180. Convention date, Nov. 3, 1942. [Class 40 (v)] Modulation of a carrier wave is effected by coupling the source 1, Fig. 1, to the load 7 through an impedance-inverting network 3 composed of series and shunt reactances 8, 9, each of which is varied by the signal to control the output current in the load. The three reactances may be arranged as shown, or as a T-network, all the reactances being equal in value and two of them of opposite sign to the other one. One of the reactances, e.g. the inductance 9, may be simulated and replaced by the network shown in Fig. 5, comprising an impedance-inverting network 10, 11 closed by a capacity 12. At the terminals 14 the variable capacity 12 appears as a variable inductance. The variable capacities may take the form, as in Specification 522,477, of pairs of plates 21, Fig. 13, between which passes a stream of electrons from a cathode 23 to a target 27. The electrons are accelerated by an electrode 25, and the density is controlled by an electrode 24 to which the modulating voltage is applied. A screen 26 shields the plates 21 from the voltages applied to the electrodes 24, 25 and also prevents return of electrons from the target 27.

Title: Improvements in or relating to hydrostatic transmissions
Inventor: BURRETT THOMAS MARK
IPC: F16H61/46
Filed: 1961-05-18
Abstract: 956,396. Hydrostatic transmissions. R. C. PEARSON. April 2, 1962 [May 18, 1961], No. 18239/61. Heading F2C. A vehicle hydrostatic transmission system comprises a variable output pump 2 supplying in parallel two variable capacity motors 21, 22, the fluid flow from which is regulated by a manually-operated steering valve 43 in series with a self-adjusting valve 53 which maintains the speed differential of the motors as determined by valve 43, constant by restricting the flow of the faster motor to maintain the vehicle on a substantially constant radius or straight path despite variations of load on the individual motors. Duplicates of the valves 43, 53 and check valves 47, 48, 55 and 56 are provided to prevent steering reversal during reverse drive or overrun conditions. The hydraulic pressure and return lines 15, 16 from the reversible pump to the motors are interchangeable. Hydraulic supply line pressure acting on the face of piston 39 against the bias of spring 40 increases the motor displacement through links 30, 31 with increase in line pressure. In forward drive with line 16 under pressure fluid flows to the motors through check valves 47, 48 and lines 49, 50 and the return flows from the motors 21, 22 respectively enter ports 52 and 55 of valve 53 and thence pass outwardly through the axial bores 65 and 64 of the free-moving or lightly spring-centralized valve spool and through lines 61 and 63 to valve 43 where the flows are combined to pass through line 72 to pump return line 15. Upward movement of steering control 46 for example moves lands 68 and 69 to respectively obstruct port 67 and uncover port 66 to provide a pressure differential between the flows from the two motors in lines 61 and 63 and between the end faces of lands 57, 58 of valve 53, thus displacing the valve spool upwards so that land 58 restricts inlet port 52 and hence reduces the output of motor 21. Should the pressure differential determined by steering control 46 be upset by a change in the motor load the outlet of the faster motor will increase and acting on the corresponding land of the self-adjusting valve spool will move the spool to restrict the flow from and hence reduce the speed of the faster motor. Specifications 902,185 and 941,735 are referred to.
