IPC: H04N5/232
Abstract: 1,047,260. Television. MARCONI CO. Ltd. March 23, 1964 [April 17, 1963], No. 15210/63. Heading H4F. In a television equipment for a mobile craft the internal image scanned by the camera is maintained in a fixed position by a deflecting coil system which operates on an electron beam and which is energized from an attitude responsive inertia control system mounted in the craft. An optical system focuses an image of a target on to a photo-cathode the emission from which falls on a fluorescent screen which produces a charge image on an adjacent photoconductive layer which is scanned to develop video signals. The electron emission from the photo-cathode is positioned automatically by signals from an initial system so that the beam falls on the fluorescent screen irrespective of craft attitude changes.

IPC: B60T8/26
Abstract: 1,050,779. Hydraulic brakes. BUDD CO. Sept. 7, 1965 [Sept. 18, 1984], No. 38221/65. Headings F2F and F2V. A braking system is described wherein the pressure of hydraulic fluid supplied to the rear wheel brakes of a motor vehicle is reduced in proportion to that supplied to the front wheel brakes when the pressure of fluid supplied from a master cylinder exceeds a particular value. The value may lie in the range of 200-500 p.s.i. and the pressure reduction may be of a factor of 1À2 to 1À4. The effect is achieved by a valve 14 connected at 20 to the system master cylinder and at 22 to the rear, drum, brakes. A two-part piston 24, 28 is urged towards the outlet port 22 by Belleville washers 36. At low brake actuating pressures fluid passes through passages 35 around secondary piston port 28 and through a passage 29 to the rear face of piston 24 and to the outlet 22. At a higher pressure the thrust on the large diameter of primary piston 24 overcomes the Belleville washers 36 and the piston moves leftwards to close valve faces 31, 32. At higher pressures the pistons 24, 28 move together to act as a stepped piston pressure reducer. The Belleville washer chamber is vented to atmosphere by a port 37. In another embodiment (Fig. 5, not shown) fewer Belleville washers are employed and a spring is employed in chamber 23. A spring-loaded plate valve is positioned in the line to the front (disc) brakes to reduce the pressure from the master cylinder by approximately 110 p.s.i. as it passes to the cylinders of those brakes. This valve may be combined in the structure of the previous valve.
