Abstract: 1294925 Image pickup tubes GENERAL ELECTRIC CO 26 Jan 1970 [1 May 1969]) 3761/70 Heading H1D A method for making a reinforced target structure for a camera tube comprised rigidly mounting a finely divided metal mesh 44 on a support frame 42, applying a removable film to one side of the mesh depositing a Mg layer 46 on same, oxidizing the Mg to form a homogeneous membrane of magnezium oxide, and removing the removable film so that the membrane is in line contact with the mesh and tightening the latter to ensure rigidity. The mesh may be of Ni of gauge 1000 lines/inch or fine mesh to open area sufficient to provide 60% light transmission and 0À2 mm. thickness, and tightening may be baking in a reducing atmosphere. The mesh may be formed by electro deposition on ruled glass and the Mg may be deposited in a mount to provide a 400 to 600 Š (e.g. 500Š) thick membrane when oxidized. The removable film may be formed from nitrocellulose dissolved in an organic solvent such as amylacetate floated on a water surface, the solvent being allowed to evaporate to leave a plastic film which is applied to the mesh by raising the mesh quickly through the water to pick up the film. The membrane may have a lateral resistivity three orders of magnitude greater than the transverse, in a membrane with 300Š crystals with a 500Š thickness. Mesh 44 is preferably welded to ring 42 and the amount of evaporated Mg determined by electrical characteristics. Oxidation may be by baking in an oxidizing atmosphere #400‹ C. this also vaporizing the plastic film. The target may be in a camera as in Fig. 1 (not shown) and vibration isolation means may be included although this is not necessary to avoid microphonics. The target may be in a direct or return beam tube, and in the latter, exhibits antihalation properties.

A single projection 4c is preferably provided, as in Fig. 1, opposite the gap but, as in Fig. 4 (not shown), two projections may be disposed opposite one another, each angularly displaced from the gap by 90 degrees. In use the inner diameter of the annulus abuts an outer member, e.g. a wheel hub (3) or socket (7), and the projection(s) 4c passes through a slot (3a), (7a) in the outer member to engage in a circumferential groove (la), (5a) in an inner member, e.g. an axle (1) or spigot (5), such that the two members cannot move relatively axially but are free to rotate relative to each other. When the ends of the annulus are sprung apart the projection(s) disengages from the groove (1a), (5a) in the inner member, but preferably not from the slot (3a), (7a), allowing the two members to be separated.

As shown, the actuating means comprises an S-shaped cam secured on a shaft 11 which is rotatable by a mechanical or hydraulic linkage, and in abutment with slippers 6 on the shoes and provided with inclined faces 8. Rotation of the cam moves the shoes radially outwards and downwards to overcome the bias afforded by the wedging action of the inclined faces on the means 3 and the pull-off springs 4. A stop 10 on a cover-plate 14, or on the backing plate 1, prevents excessive reverse rotation of the cam and facilitates initial setting up of the assembly. The means 3 can be a fixed stop or an automatic or manual adjuster

Abstract: 1316076 Anti-skid control valve GIRLING Ltd 1 March 1972 [19 March 1971] 7445/71 Heading F2F In a brake control unit between a master cylinder and an hydraulic actuator and having an inertia-controlled valve member engageable with a seating to cut-off fluid flow therethrough, the seating is movable between a retracted position when there is no pressure at the actuator, and an advanced position when there is such pressure, and means are incorporated for preventing engagement between the valve member and the seating unless the seating is in the advanced position. Fluid for the master cylinder enters the control unit at 26 and passes through a differential piston 10 to the actuator. Pressure build-up at the actuator acts on the left-hand face of the piston 10 and subsequently advances the piston. If a vehicle, on which the control unit is mounted, decelerates above a predetermined value, or its suspension is deflected, an inertia-controlled ball 23 moves to engage the seating 29 on the piston end. This fluid flow to the actuator is cut-off and the piston subsequently retracts. The ball 23 now co-operates with a second seating 25 which has by-pass channels so that fluid once again flows to the actuator and advances the piston 10. Therefore, at a predetermined deceleration on deflection, the brakes are applied in steps to maintain the value thereof. The ball 23 is also actuated by rapid fluid flow from the master cylinder caused by rapid brake application.
