Abstract: 1,248,442. Image intensifier tubes. WESTERN ELECTRIC CO. Inc. 20 Sept., 1968 [21 Sept., 1967], No. 44815/68. Heading HID. The preparation and use of field emission cold cathodes formed of a mosaic of closely spaced needles perpendicular to and projecting from a substrate, the needles having a minimum density of five per square millimetre, and maximum tip diameters of the order of a micron, are described. In the image intensifier shown, 22 and 23 are the substrate and needle array of a photo-sensitive high-resistivity silicon cathode of the above type, cooled by liquid nitrogen 31. The optically transparent anode grid 24 is connected via lead 27 to a transparent conductive coating 25 which covers one-half of the lower end surface of the envelope and on which a fluorescent screen 26 is formed. An optical image is focused upon the cathode through the window 33 which is coated with a transparent conductive coating 34 which acts as a repeller electrode deflecting the resultant electron image on to the fluorescent screen 26. Reference is also made to the use of an axial magnetic field for focusing the electron image. Preparation of the cathodes.-In one example, a melt of high purity aluminium and nickel is unidirectionally solidified to produce an ingot having the approximate composition Al 3 Ni, which is cut into pieces which are polished and etched to expose filaments having rounded tip diameters of less than one micron and uniform lengths equal to about three diameters. The photo-sensitive silicon cathode of Fig. 2 is produced by evaporating gold on a silicon wafer at the desired needle sites and heating in hydrogen, to form a mosaic of molten Au/Si alloy droplets, whereafter hydrogen saturated with silicon tetrachloride is passed over the wafer to deposit silicon at the droplet site. The wafer is then raised to and maintained at a higher temperature in a flow of hydrogen, to evaporate the gold and thereby decrease the volume of the liquid solution with a concomitant decrease in the diameter of the growing crystals, until the gold is totally exhausted.

A pneumatic braking system comprises a distributer valve controlling one or more braking sections, each section having a corresponding air tank C 1 , C 2 , C 3 . An emergency, pneumatic, distributer operating device A2 is connected through a manual control valve H to an auxiliary air tank D which is fed from one air tank C2 through a one-way check valve F such that, on the failure of the distributer actuating means B, 72, the manual control valve H is operated to effect emergency braking through device A2. In the construction shown the auxiliary air tank is integral with air tank C2 but it may also be separate (Fig. 2, not shown). The check valve F includes a spring-loaded disc valve and an electrical auxiliary tank pressure indicating means (Fig. 3, not shown). The manual control valve H (Fig. 4, not shown) comprises a piston provided with a drilled stem which in the inoperative position vents the device A2 to the atmosphere through a port in the wall of the valve. The valve body and handle 58 screw threadedly engage so that, on rotation of the handle relative axial movement takes place between the body and handle. The movement depresses, through a spring, the piston and its stem, the stem seating on and then opening a disc valve to close the venting system and to pressurize the emergency pneumatic system.

Slip stubs, which comprise a plain shaft portion and a splined portion are degreased by a wet abrasive blast and transferred to a conveyor where they are gripped by chucks. Hydraulic rams 5 lift priming baths 4 so that slip stubs 3 are immersed in primer 6. The conveyor is then indexed to bring the primed slip stub over electrostatic detearing means comprising grid 7 supported on insulator 8. After excess primer has been removed, the slip stubs are dried by a current of air from a fan passing over an electric heating element. In the next coating stage drive rollers 11, 12 engage a support carrying the chucks. Each chuck is rotated so that the primed slip stub is in alignment with block 15 reciprocable vertically by ram 16. Centre 35 of block 15 can engage a complementary centre in the free end of the slip stub. Shield 13, 14 protect rollers 11, 12 and chuck 2. Spray gun 17 coats the rotating slip stub. The electrostatic spraying field is adjusted by block 15 to prevent build up of powder at the bottoms of the splines. The primed coated stubs are passed to the induction heating stage where a coil heater surrounds the splined portion in operation. A further induction heating coil is used to fuse the powder on the shaft portion. The slip stub is rotated during heating.
