Title: Improvements in or relating to the manufacture of cascade image amplifiers
Inventor: SLARK NORMAN ARTHUR
IPC: H01J9/12
Filed: 1959-03-25
Abstract: 871,206. Electrode materials and processing. ENGLISH ELECTRIC VALVE CO. Ltd. Nov. 19, 1959 [March 25, 1959], No. 10335/59. Class 39(1). A method of manufacturing a cascade image amplifier with alternating photocathodes and fluorescent screens comprises of mounting a plurality of separate membranes on a conical wheel 15, Fig. 2, in an evacuated space, heat treating and other processing of the membranes to form photocathodes, as by an oven 14, transferring the processed photocathodes to predetermined positions in the tube envelope 7, bringing the separated parts 7, 12 of the envelope together by a hand wheel 10 and bellows 9, releasing the vacuum inside 1, 2 and removing the sealed envelope 7, 12. The conical wheel has a number of glass tubes 18 on one end of which the membranes are mounted and the end closure 12 for the envelope may be separate as shown and have a fluorescent inner coating or may be mounted on the wheel 15 and have a photocathode coating, Fig. 3 (not shown). The. glass tubes 18 serve as spacers in the completed tube and are held lightly to wheel 15 by spring holders. The conical wheel 15 is energised by a magnetic drive operable from outside the chamber and oven 14 holds the evaporators for the photocathodes. When a photocathode on 18 is brought in registry with envelope 7 by rotation of conical wheel 15 part 6 moves by hand wheel 10 to close the tube envelope and then opens again so 18 and its membrane and photocathode are disengaged from their spring holder and inserted in the tube envelope. This process is repeated as often as desired to get a chain of photocathodes within the tube envelope. Hand wheel 10 is now removed and a hydraulic press lowered over the apparatus and used to apply pressure between blocks 19, 20 so as to cold weld copper flanges 7<SP>1</SP>, 12<SP>1</SP> together after which the envelope 7 can be removed. A getter is placed on the edge of 12 or on the inside of an extra glass mount 18 having no membrane (the last mount 18 to be inserted in 7). Tubes 18 can have an interior conductive coating or helix coating to give a uniform potential gradient in the tube, and the membranes are of lead glass to absorb x-rays. 5 are inspection windows in the top and sides of helmet lid 1 which is of stainless steel. An evacuating pipe is attached at 3. Getters are fired inside chamber 1, 2 before processing is commenced.

Title: Process for the preparation of soot granules
IPC: B01J20/20
Filed: 1973-03-06
Abstract: 1423384 Carbon black granules SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 6 March 1973 [8 March 1972] 10744/73 Heading C1A Soot granules are prepared by mixing a pumpable suspension of soot in water, i.e. an aqueous soot suspension containing not substantially more than 5% by wt. of soot, with a particulate solid organic and/or inorganic binder, removing water from the resulting mixture to form a paste, forming said paste into granules and drying said granules. The dried granules may then be heated at a temperature in the range 120‹ to 3000‹ C. in a non-oxidative atmosphere, i.e. an atmosphere containing no free oxygen or not exceeding 10% by volume of free oxygen. The binder may be clay in an amount of 5-200 wt. per cent based on the soot, and the clay containing particles may be heated to 500‹ to 2000‹ C. after drying. The binder may also be a synthetic organic polymer, and may have a fibrous structure, the thermal treatment in this case being at 300‹ to 400‹ C. Another possible binder is glass powder which may be added in an amount of 2 to 40% based on the soot, the following thermal treatment then being carried out at a temperature within the softening range of the glass. A further suggested binder is bitumen, which is added to the soot suspension as a suspension of bitumen powder in water, preferably in an amount of to 20% by wt. bitumen based on the soot. In this case the thermal treatment may be at 350‹ to 800‹ C. and may be carried out in an atmosphere containing steam. Another suggested binder is water-glass when the thermal treatment is carried out at 120‹ to 1000‹ C. The initial pumpable suspension of soot may be obtained by washing, with water, gases obtained by the partial combustion of hydrocarbons. The granules so obtained seem to be useful absorbent materials.
