Title: Improvements relating to two colour television systems
IPC: H04N9/27
Filed: 1967-02-06
Abstract: 1,155,152. Colour television. INTERNATIONAL POLAROID CORP. 6 Feb., 1967 [7 Feb., 1966], No. 5550/67. Heading H4F. In a colour television system operating in accordance with the " red-white " principle of colour reproduction the colours forming the receiver image are produced with a cathode-ray tube having a screen displaying two colours only at line rate in the sequence R, R, W, R, R, W &c. Although reference is made briefly to a system in which the transmitter image is analysed in terms of two colours, red and green, the invention is described primarily as applied to a system in which the image is analysed in terms of three colours and the signals are transmitted by the N.T.S.C. method. The receiver uses a cathode-ray tube having a double-layer screen, the colour of the light from which is changed by altering the electron beam velocity by changing the tube screen potential. The electron beam is thereby caused to penetrate and excite either one (the inner) or both screen layers. The inner and outer layer may produce respectively red and cyan (i.e. minus red) light, so permitting operation on a strict red-white basis. Alternative arrangement referred to employs red and green, or orange and cyan screen layers. In a first embodiment, Fig. 1 (not shown), the receiver demodulates the N.T.S.C. signal in the conventional manner to obtain Y, I and Q signals and these are matrixed to obtain R, G and B signals. The R and G signals only are selected and applied to modulate the cathode-ray tube through a gate or switching arrangement operating at line rate in the sequence R, R, G, R, R, G &c. Simultaneously the screen potential is switched between a low and a high value such that the corresponding reproduced colours occur in the sequence R, R, W, R, R, W &c. In a second embodiment, Fig. 9 (not shown), a single axis demodulator, which is supplied with two reference oscillations 180 degrees out of phase, demodulates the colour sub-carrier to derive simultaneous red and cyan (i.e. minus red) signals. These are then gated to the tube in the sequence R, R, C, R, R, C &c., whilst the tube is switched to produce colours in the sequence R, R, W, R, R, W &c. Scanning is effected with 525 lines per picture and as a consequence no change in switching sequence is necessary to maintain a stationary colour line pattern. Black-andwhite reception is provided by simply maintaining the high value voltage on the tube screen so that white light is produced. Alternatively a warm" " white reproduction may be provided by changing the sequential operation of the screen potential switch so that the tube produces light in the sequence W, W, R, W, W, R &c.

Title: Improvements relating to automatic firearms
IPC: F41A9/16
Filed: 1962-02-14
Abstract: 933,746. Automatic fire-arms. BOFORS A.B. Feb. 14, 1962 [Feb. 22, 1961], No. 5663/62. Class 92. Relates to an automatic fire-arm in which a loading pendulum or tray 10, Fig. 1, is supported for angular movement between a position in which it constitutes an extension of a hoist 4 and a position (see Fig. 2) from which ramming of a round can be carried out regardless of the elevation movement of the firearm. The loading pendulum 10 is moved between these positions by a driving device which gives a'lever 18 an oscillating movement of fixed amplitude, the lever being connected to the pendulum by a link mechanism which is controlled in dependence upon the position of elevation of the fire-arm whereby to reduce or increase the angular movement given to the pendulum by the same amount as the elevation is increased or reduced. A lever 5 fixed to the elevating recoil jacket 1 is articulated to one end of a guide bar 6, the other end of which mounts a roller 7 running in a guide 9 fixed to a non-elevating part 2 of the mounting. The loading pendulum 10 is supported for rotation about trunnion axis 3 and is rigidly connected to a lever 11. A driving bar 12 incorporating a shock-absorbing buffer 13 has one end articulated to the lever 11 while the other end mounts a roller 14 running both in a driving guide 15 and in a groove 8 in the guide bar 6. One end of the guide 15 is pivoted at 16 and its other end pivoted to a driving bar 17 connected to the lever 18. When the driving mechanism (not shown) moves the lever 18 from the position shown in Fig. 1 to that of Fig. 2, the parts move as shown and the pendulum 10 is moved to the loading position. If the fire-arm is elevated with the loading pendulum 10 in the hoising position, the parts move as shown in Fig. 3 and the pendulum is not actuated during elevation. If the gun is elevated with the loading pendulum 10 in the ramming position, the position of the pendulum relative to the recoil jacket 1 will not be changed (see Fig. 4) and movement of the lever 18 from the Fig. 3 to Fig. 4 position will cause a reduced movement of the pendulum 10, the reduction in angular movement compared with that shown in Figs. 1 and 2 corresponding to the increase in elevation. A modified form of link mechanism is described with reference to Fig. 6 (not shown).

Title: Improvements in apparatus for rolling glass
IPC: C03B13/04
Filed: 1923-03-02
Abstract: 216,586. Pilkington Bros., Ltd., and Le Mare, E. B. March 2, 1923. Rolling. - In a process of producing a continuous strip of glass by rolling molten glass as it issues from a tank furnace, the strip as it issues from between the rollers is drawn over a flat stationary bed on its way to the lehr, the bed being of such a length that the plastic strip becomes flattened and sets before it passes on to the rollers in the lehr. The glass issues from the tank 4 by a shoot 5 and forms a pool 6 in the pass between the rollers 7, 8. The shoot is provided with side walls and a crown 10, and the space thus formed is heated by burners 11. An adjustable gate 14 regulates the arc of contact between the pool and the roller 7, and this arc is less than that between the pool and the roller 8. The glass strip 15 as it issues from between the rollers passes on to a stationary bed 16, 23 and thence into the lehr 17, where it is supported on rollers 18 which are also rotated to draw the strip. The bed consists of a curved portion 23 and a flat portion 16 part of which may be covered by a hood 19 to enable the rate of cooling of the strips of glass may be controlled. The flat bed enables the sheet to become flattened by its own weight, and the length of the bed is such that the strip has become sufficiently hardened by the time it enters the lehr to resist deformation when passing over the rollers 18. The shoot 5 may be replaced by a short horizontal conduit or even a slot in the wall of the tank. The rollers are preferably arranged, as shown, with the upper one in advance of the lower, but they may be vertically one above the other or their axes may be in the same horizontal plane. The lower roller is preferably of greater diameter than the upper roller, and may be replaced by a chain table of any known construction.

Filed: 1940-04-08
Abstract: 540,329. Separating air from liquids. STEVENS, A. H. (Wayne Pump Co.). April 8, 1940, No. 6341. [Class 1 (i)] A device for separating air from liquids, particularly for use in conjunction with a pump in liquid dispensing apparatus comprises a main chamber 154 with inlet 20 and outlet 26, communicating by a restricted aperture 158 with a secondary chamber 160 which has a pressureoperated venting valve 164 and an outlet 186 for liquid. The aperture 158 is controlled by valve 176 operated by a float in the secondary chamber. The inlet of the main chamber is connected to the pressure side of the pump 14. The liquid return pipe 146 from the secondary chamber is connected to the inlet 142 of a sleeve valve, Fig. 6, mounted on the pump. The sleeve valve carries a piston 126 the opposite sides of which are subjected to the fluid pressures prevailing on the suction and pressure sides of the pump by means of passages 108, 110 respectively. While air is being pumped the sleeve valve remains closed, but when the liquid passing through the pump is air-free the pressure on the delivery side opens the valve allowing liquid accumulated in the chamber 160 to return to the suction side of the pump.
