Patent GB-507059-A (GB)
Abstract: 507,059. Cathode-ray tubes. McGEE, J. D., and LUBSZYNSKI, H. G. Dec. 3, 1937, No. 33420. [Class 39 (i)] A discharge tube for the generation of picture signals comprises a double-sided mosaic screen consisting of elements 5, in the interstices of a conducting grid like structure 3 and insulated therefrom, the insulation 4 only partially covering the grid so as to leave the scanned side bare and adapted to emit secondary electrons when scanned by a cathode ray or light beam, means for scanning the exposed side of the grid like structure, collecting electrodes 10, 11 and means for maintaining the grid at a negative potential with respect to the collecting electrodes so as to reduce the spread of electrons over the mosaic. The mosaic elements are positively charged by projecting an optical or electron image as described in Specification 442,666 on to the screen, and secondary electrons are collected by an electrode 12. Where an electron image is projected on the screen, one or more stages of multiplication may be employed, and in order to reduce blurring in the images of fast moving objects, the image is projected on to the screen only during frame return periods either by using a mechanical shutter or by reducing or reversing the accelerating field controlling the electron image. The screen may be made convex towards the incident image and the scanning beam of sufficient depth of focus to remain substantially in focus over the whole area of the screen. The scanning beam may be a cathode-ray generated by the gun 9 deflected by electrostatic plates or coils 11a. Alternatively the scanning means may be a light beam produced by traversing a cathode-ray beam over a luminescent screen, in which case the scanned side of the grid-like structure is made photo-sensitive and the same side of the mosaic elements is treated so as not to be photo-sensitive. The screen may be made as described in Specification 506,800, and for light-scanning a metallic layer of gold or other material which has little affinity for photo-sensitive materials is applied to the insulated grid like structure. A further layer of a suitable material is applied according to whether an optical or electron image is to be projected on to the screen. The scanned side of the mosaic elements may be treated with carbon &c. so as to have very little secondary emission and the potentials of the electrodes are arranged so that these elements stabilize at their. second cross-over point as described in Specification 475,928, and control the secondary emission from the grid structure in the manner of a control grid.

Abstract: 1,131,742. Window cleaning apparatus. CRADLE RUNWAYS Ltd. 27 Feb., 1967 [1 Dec., 1965], No. 51008/65. Heading A4F. Apparatus for automatically cleaning windows of buildings comprises a washing device which is arranged to be driven towards a window until it presses on the window with a predetermined force, the washing device being provided with a water supply and a flexible sealing member which prevents leakage of water from the device when in use. As shown in Fig. 1, the washing device 4 which is mounted by rollers 5B on a framework 5 is provided with a brush (10) (Fig. 3, not shown) rotatable by a motor 11 and a water tank 23 which is connected to a motor driven pump 26 to supply water through a pipe 28 to the brush (10). The brush (10) is surrounded by a hood 15, the rim of which is provided with the flexible sealing member 16, (17) (Fig. 3, not shown). A motor 7 is arranged to drive the washing device 4, through a rack and pinion arrangement 8, 9, transversely of the framework 5 (i.e. towards or away from a window to be cleaned) and a motor (6) (Fig. 2, not shown) is arranged to drive the washing device 4 longitudinally of the framework 5 which is supported on a cradle 1, the cradle 1 being suspended by cables from a trolley arranged on the roof of a building whose windows are to be cleaned. The motors 6 and 7 and a motor for driving the trolley are arranged in an electric circuit and are controlled by the operation of a main switch and the actuation of limit switches in such a way that after operation of the main switch the cradle is lowered from the roof of the building to a first window at which the washing device is driven to engage with a top left hand corner of the window. The washing device is then driven to and fro across the window, the cradle being suitably lowered at the end of each traversing of the window and the water being suitably sprayed on to the brush which is rotatably driven for cleaning purposes. After the first window has been cleaned the washing device is retracted from the window and the cradle is lowered to the next window for the cleaning operation to be repeated and so on. After one 'column' of windows has been cleaned the trolley is driven along the roof so that subsequent 'columns' can be cleaned, the water in the tank of the washing device being renewed each time one 'column' of windows has been cleaned.

In the embodiment of Fig. 1, oscillator 5 produces a reference sub-carrier of phase f50, Fig. 2, which is fed to B - Y demodulator 13 and a reference sub-carrier of phase f<SP>1</SP>50 which is added at 10 to the output of oscillator 9 which is of phase f<SP>1</SP>B1 or f<SP>1</SP>B2 (this phase being 90 degrees phase retarded relative to the bursts passed by gate 6) to produce a sub-carrier of phase f<SP>1</SP>51 or f<SP>1</SP>52 respectively, which is fed to switch 11 where it is phase-inverted on those lines when gate 6 is closed, and then via 90 degrees phase-advancer 12 to R - Y demodulator 14. In the alternative embodiment (Fig. 4, not shown) the output of oscillator 5 is of + (R - Y) phase and is fed via a 90 degrees phase retarder to demodulator 13 and directly to a phase discriminator receiving the output of gate 6, to produce a control voltage which is fed to a selective phase shifter to provide a signal which is in phase with or antiphase with the output of oscillator 5, and this signal is then phase inverted for alternate lines and fed to demodulator 14. Instead of the reference sub-carrier fed to demodulator 14 being phase-inverted on alternate lines, the chrominance signal may be so inverted, the reference input being of constant. phase.
