Title: Improvements in or relating to photo-electron image multipliers
Inventor: MCGEE JAMES DWYER
IPC: H01J43/22
Filed: 1956-11-30
Abstract: 819,217. Electron multipliers. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Nov. 25, 1957 [Nov. 30, 1956], No. 36622/56. Class 39(1). A photo-electron image multiplier comprises a transparent envelope 3, Fig. 1, in which are arranged a photo-sensitive cathode 1 on which an optical image is projected, a grid 12, a screen 4, which may be fluorescent, and a number of cellular secondary emissive electrodes 6 .. 10 comprising a two dimensional array of tubes 16, 17, Fig. 2, cut from a stack of long tubes soldered together. Alternatively each electrode may be a glass plate etched to form a cellular structure and provided with a metallic conductive coating. The interior of the cells thus formed are coated with secondary emissive material and the electrodes 6.. 10 are maintained at increasingly positive potentials with respect to the cathode grid 12 being at a higher potential than both electrode 6 and cathode 1 as shown in Fig. 1. Corresponding cells in each electrode are accurately aligned to provide a number of straight parallel channels, each one corresponding to a separate elemental area of the original electron image. The electrons are constrained in their respective channels by a number of arrangements which chiefly employ the direction of the electric field between successive electrodes. One such arrangement is shown in Fig. 4 in which grids 19, 20 are placed in front of electrodes 7, 8 and connected respectively thereto, the electrons following paths such as those shown by the lines 21. A similar effect may be obtained without grids 19, 20, but with increased length of the cells, Figs. 5, 6 (not shown). In three further arrangements the secondary emission is obtained from electron permeable membranes covering the front faces of the cellular electrodes. In these arrangements the cells may be fairly long and closely spaced, Fig. 7 (not shown), or relatively short with larger spacing, the potential difference between successive electrodes being greater, Fig. 8 (not shown). Fig. 9 shows the same arrangement as Fig. 8, but an axial magnetic focusing field is provided by a solenoid 28 so that a smaller potential difference between electrodes 6, 7 covered by membranes 26, 27 is required. The membrane may comprise a thin film of silica or alumino coated on the side remote from the photo-cathode 1 with a secondary emissive layer of antimony or bismuth activated by caesium. In one embodiment of the device the faces of the cellular electrodes are cut parallel to each other but obliquely to the axes of the cells, Fig. 10 (not shown). In another embodiment a further cellular electrode 32, Fig. 11, is placed in front of grid 12 and algined with electrodes 6, 7, 8. The inner surface of this further electrode is coated with photo-emissive material and an image 33 of a source 31 is focused on the front face of electrode 32 by a lens system 29. Various dimensions of the cells, their spacing and the potential differences applied are given in the Specification.

Title: Process for the treatment of malt
Inventor: COMRIE ALAN ARTHUR DOUGLAS
IPC: C12C1/047
Filed: 1964-09-08
Abstract: Anaerobic respiration is induced in green malt, thereby producing acidity and increasing the products of enzymic activity e.g. soluble carbohydrate and nitrogenous matter, by holding green malt having an extract percentage of at least 75% of the potential extract, in a sealed container (or in an open container having a blanket of inert non-toxic air-excluding gas lying over the green malt) and inducing an anaerobic atmosphere therein which is maintained for at least 24 hours, and the treated green malt is then removed from its anaerobic atmosphere for direct use or for further processing.  Where the malt occupies less than about 75% of the container volume, it is preferred to supplement the elimination of oxygen in the container due to the contained respiration of the malt, by displacement with carbon dioxide or nitrogen.  The green malt prior to being placed in the container may be sprayed with water, the excess water being allowed to drain away, or macerated.  The green malt may be maintained in the anaerobic atmosphere at a temperature in the range 15 DEG -35 DEG C. and subsequently may be dried at a temperature in the range 50 DEG -60 DEG C. or used for the preparation of wort, malt syrup or dried malt extract.  Examples are directed to treating green malt at temperatures in the range 15 DEG  -35 DEG C. for periods ranging from 2 to 28 days.

Title: Method for producing carbon dioxide ice
IPC: C01B32/55
Filed: 1961-10-18
Abstract: 938,339. Solidifying gases; dispensing liquids by gaseous pressure. L. MULLER. Oct. 18, 1961 [Aug. 9, 1961], No. 37317/61. Classes 8(2) and 102(2). [Also in Group V] A method of producing carbon dioxide ice, comprises applying to highly compacted carbon dioxide snow, under conditions permitting the temperature to be kept close to the triple point in a chamber which is not hermetically sealed but is open to the ambient atmosphere, a mechanical pressure which exceeds the vapour pressure of the carbon dioxide at the triple point. The mechanical pressure is preferably not substantially less than 10 Kg. per sq. cm. or substantially more than 20 Kg. per sq. cm. As described apparatus for carrying out the above method comprises a hydraulic press having an upper ram 1 and a lower ram 2, the rams being adapted to be independently raised or lowered. Located between the rams is a fixed block 5 having an opening 6 the diameter of which in cross-section slightly exceeds the diameter of the upper ram 1 but which is adapted to receive both rams. In operation the ram 2 is positioned with its top face flush with the underside of the block 5 thus defining the chamber in which is disposed the compacted carbon dioxide snow on to which is then lowered the ram 1. Vapour from the snow escapes to atmosphere through the gap between the ram 1 and the opening 6. This operation is repeated several times until the temperature of the operating parts of the press has dropped slightly below the triple point. Pressure of about 10 to 20 atmospheres gauge is then suddenly applied to the snow. The resultant block of carbon dioxide ice which is stated to be translucent and substantially non-porous is thereafter ejected from the opening 6 by the ram 2. The block 5 is preferably provided with a heating element 9 to provide latent heat required when the process is repeated rapidly. The carbon dioxide ice may be produced in the form of small bodies, e.g. cones, rods or hollow cylinders, by the provision of a die having suitably shaped recesses and disposed on the ram 2. The small bodies may be used to provide the propellant in aerosol type dispensers.

Title: Method of forming leads on semiconductor devices
Inventor: CERNIGLIA NINO P
IPC: H01L23/485
Filed: 1968-08-05
Abstract: 1,211,922. Semi-conductor devices. SYLVANIA ELECTRIC PRODUCTS Inc. 5 Aug., 1968 [4 Aug., 1967], No. 37325/68. Heading H1K. [Also in Division C7] The Specification discloses a method of forming connecting leads on a semi-conductor body, the body in the embodiment described being of silicon and containing many diffused transistors provided with platinum silicide contacts (16) lying in apertures in a silicon oxide film 11. The top surface of the body is coated successively with layers of titanium 35, molybdenum 36, and gold 37 without breaking vacuum in, for example, an electron beam evaporator or a cathodic sputterer. The surface is then PR-masked to leave only the lead areas 45, 46, 47 exposed and the gold layer thus exposed is then built up in thickness (at 42), by electroplating. After remasking, the gold layer is still further built up in the areas (45a, 46a, 47a) which are to form beam leads in the finished transistor. After removal of the masking layer unwanted metal between the leads is etched-off. Specific etchants are used which attack only the material of the layer involved in that step. An aqueous solution of potassium iodide and iodine removes the thin gold film 37 between the leads -the thick gold layer 42 is slightly thinned but retains the bulk of its original thickness. A mixture of nitric, phosphoric and acetic acids is then used to remove the molybdenum layer 36 except where it is protected by the overlying gold layer 42, and hot concentrated sulphuric acid is then used to remove the thus exposed portions of the titanium layer. The devices are completed by masking the upper surface of the semi-conductor body, etching the underside to reduce the overall thickness of the body, and by then remasking and etching to separate individual transistors with projecting beam leads which may be, for example, welded to circuit connections.

Abstract: 875,658. Cartons : packages. CHRISTENSSON, O. V. Nov. 4, 1959 [Nov. 12, 1958 ; Feb. 23, 1959], No. 37404/59. Classes 18 and 94(1). A carton as in Fig. 1 adapted to be vacuum closed with end closing flaps 12-15 connected to short sides 11 and flaps 16 19 connected to long sides 10 has an inner lining 20 attached to the inside of the carton at separate adhesion points e.g. 33-35, see Fig. 3, of such size and distribution that the adhesive strength between carton and lining suffices to keep the lining attached to the carton during folding from the blank and closing of the end flaps, but not after evacuation of the lining and subjection of the assembly to atmospheric pressure. In this way, deformation of the carton due to adhesion to the lining after vacuum-closing is avoided. Pasting strip 31 on the blank adheres to connection flap 32 on its reverse side to form the tubular carton. In the embodiment shown, the bottom part 21 of the lining 20 (which is preferably made of a weldable transparent plastics material) is flattened and welded together before closing the end closing flaps 14, 15, 18, 19. In another embodiment, the lining is in bag-form before the blank is folded about it.
