Title: Improvements in or relating to methods of forming a pattern of conducting material ona substantially insulating support
Inventor: SAUNDERS PETER JOHN
IPC: H01J29/43
Filed: 1961-04-25
Abstract: <PICT:1006076/C6-C7/1> A method of forming a pattern of conducting material on a substantially insulating support, e.g. for a mosaic screen in a light scanned television pick-up tube, comprises providing an electrode 2 on one side of the support 1 by depositing a layer of electrically conducting material thereon, dispersing a conducting stencil 6 close to the other side of the support, applying a potential difference between the electrode and the stencil to cause the stencil to be electrostatically attracted towards the electrode thereby being held in contact with the other side of the support, depositing material to form a plurality of discrete elements on to the other side through the stencil and subsequently dispersing the material of the electrode to remove the electrode.  In one embodiment, the insulating support is a glass and the electrode 2 is of tellurium, the stencil being a fine metal mesh. Antimony, which is subsequently sensitized so as to be photosensitive is evaporated from an evaporator composed of platinum coated molybdenum wire of 0.01 inch diameter or of a coil of tungsten wire.  The processing may be carried out within the pick-up tube itself, the electrode 2 removed during the bake-out period of the tube.  The metal mesh may be moved a required distance from the support and subsequently used as an electrode during operation of the tube.  In a further example, after the removal of the mesh, a layer of chromium is evaporated over the discrete elements and the support, and the elements subsequently etched off, leaving a mesh-like pattern of chromium on the insulating support.

Title: Improvements in or relating to wheel brake systems for aircraft
Inventor: CLIFTON JOHN ROBERTSON
IPC: B64C25/44
Filed: 1954-05-21
Abstract: 753,075. Aircraft brakes. NORTHROP AIRCRAFT, Inc. May 21,1954, No. 15049/54. Class 4. [Also in Group XXXIV] In a brake system for aircraft the brakes are normally applied hydraulically by pressure fluid supplied at 11 and passed to the wheel brakes under control of valves 8.

Title: Improvements in or relating to combined manual and power operated braking systems
IPC: B60T13/24
Filed: 1954-05-21
Abstract: 746,722. Fluid-pressure servo brakes. BENDIX AVIATION CORPORATION. May 21, 1954 [Aug. 31, 1953], No. 15056/54. Class 103 (1). In a pneumatic servo hydraulic braking system, in order to avoid the possibility of the master cylinder bottoming, when air pressure for servo operation -is not available and it is necessary to apply hydraulic pressure to the brake cylinders by direct transmission from the master cylinder piston, the stroke of the pedal or treadle 93 is arranged to be automatically increased from the dotted positions shown in Fig. 1, and corresponding to applied and release conditions, when the servo unit is in operation, to that shown in full lines. This action is provided by securing a fluid pressure responsive diaphragm type actuator 104 to the pivoted lever 94 which is connected by rod 95 to the master cylinder piston, so that when vacuum is not operative on the diaphragm the spring 111 causes it to force a wedge member 109 between arm 103 and the lever 94, thus raising the pedal 93 to the full line position. In the embodiment shown in Fig. 3, vacuum applied to chamber 127 of a similar actuator, causes wedge member 123 to act upon the arm 122 of the pedal 119 so as to move it to a reduced stroke position, but since in this position the piston 116 of the master cylinder has already covered make-up port 136, it is necessary to provide a vacuum operated diaphragm 143 which automatically opens through rod 142 a non-return valve 140 to allow communication with the reservoir. Specification 580,468 is referred to.
