Work-holders 33 are carried by an indexable endless band 32, the tension of which may be pre-stressed by the action of adjusting screws (90), (92), (Fig. 14, not shown), actng on an idler drum (30). The work-holders 33 carry platforms 176 for work 178 which may be operated on in dwell periods of the band 32 by tooling 180. The latter is reciprocated by action of a cam-shaft 64 the drive of which, together with the drive of a second cam-shaft 66, is taken from a gear-box 108. The latter also supplies an indexing drive 34 for the band drive drum (28), (Fig. 10, not shown), via an adjustable coupling 114. The latter comprises a pin (118), (Fig. 12, not shown), extending axially from the peripheral region of a driven plate 116 which is sandwiched between adjustable screws (120), (122) carried by a driven member (124). A similar coupling (Fig. 13, not shown), is provided in the drive to the shaft 64. The endless band 32 has holes 164 which engage pins (170), (Fig. 11, not shown), on the drive drum (28). The band is positively held in the dwell periods by the action of a pin (150), (Fig. 10, not shown), which is projected into one of a peripheral series of apertures (146) in the drum (28) by linkage operated from the cam-shaft 66. The frame of the machine is built up from a series of modular frame units.

Abstract: 1,125,791. Colour television tubes. RAULAND CORP. 15 Sept., 1965 [24 Sept., 1964], No. 39316/65. Heading H1D. In a method of making the multi-dot or multi-line phosphor screen of a colour television receiver tube a photo-sensitive resist is applied to a transparent screen support having a filter layer transmissive only of red light, elemental areas of the resist are exposed and developed, unexposed areas are removed, the screen support is etched to remove the filter layer in the areas unprotected by the resist and the red phosphor is applied only over those areas which bear the filter layer. The blue and green phosphors are then applied successively by photo-resist methods to the remaining areas of the screen, the blue and green phosphors incorporating appropriate filter material in their composition, e.g. as described in Specification 834,030. Finally an aluminium layer is applied and the screen baked. The filter layer for the red phosphor may comprise red-coloured glass or an inorganic chemical such as cadmium sulpho-selenide, or a glass colorant such as copper silver stain may be processed through heat treatment to enter the glass lattice of the screen support. The photo-sensitive resist is of the type rendered insoluble to water on exposure to light. The etching step is by the use of hydrofluoric acid and the red phosphor is deposited e.g. by a slurry or dusting technique or by a further photo-resist step.

As described, the amplifier comprises a power jet nozzle 15, Fig. 1, two control signal nozzles 16, 46 and two receiving or output channels 17, 18. The channels 17,18 are connected by feedback passages 71, 72 to nozzles 71b, 72b so that, in operation a bi-stable switching action is obtained. In another example, Fig. 2, the power stream from the nozzle 80 normally passes into output channel 81 and is diverted to the channel 86 on application of a pressure pulse to control nozzle 83.
