Title: Improvements in or relating to storage electrode
IPC: H01J29/41
Filed: 1962-12-31
Abstract: Borate glass for a target electrode in a television pick-up tube (see Division H1) comprises a network of boron oxide and from 20 to 40 mole per cent of alkaline earth metal oxide on the basis of the B2O3, to which is added at least 15 but not more than 80 mole per cent of a multi-valent metal oxide or oxides.  The second constituent (network modifier) may be the oxide of calcium, barium, strontium, magnesium or a mixture of two or more.  If magnesium oxide is used the immiscibility is overcome by the addition of aluminium oxide or potassium oxide as part of the second constituent in the proportion 1 to 5 mole per cent of the ultimate glass, added before or after melting. The third constituent is preferably vanadium pentoxide and iron oxide, and a particular composition is given.  The glass is homogenized by grinding after cooling, and then is heated to 1000 DEG C. and blown into a bubble. The target is made by cutting an area from this bubble, softening and flattening it, and securing it to a ring, after which it is coated on one side with an oxide.

Title: Heat-treated flour process for making it and products containing it
IPC: A23L7/10
Filed: 1971-10-26
Abstract: 1327134 Conditioning flour OGILVIE FLOUR MILLS CO Ltd 26 Oct 1971 [26 Oct 1970] 49591/71 Headings A2Q and A2B Cereal flour is heat treated in a manner to produce a free-flowing dry product comprising a non-gelatinised or non-hydrolised starch fraction, a denatured protein fraction, and substantially no active α-amylase or lipid-degrading enzymes, the product being characterised by having a moisture content of between 4% and 10% by weight, and yielding a cooked aqueous slurry with a Hagberg falling number of at least 240 secs. In apparatus for carrying out the treatment flour, e.g. wheat flour, with a moisture content of 15% by weight is delivered through air-lock valves 19, 20 to a screw conveyer 22 and thence through a rotary pressurelock valve 30 to a steam-jacketed pressure vessel 23 where it is heated to a temperature of 120‹ to 160‹C. The residence time in the vessel 23 is between 5 and 60 minutes. During this time the flour, which is urged outwardly against the wall of the vessel, and longitudinally towards an outlet 40 by a rotor 39, is enveloped by steam resulting from its moisture content. After discharge through a pressurelock valve 41 the flour is entrained in a stream of cooling air by which it is conveyed through a drying duct 45 to a cyclone 46 and hopper 47. Flour from the hopper and from a dust collector 48 is discharged through rotary airlock valves 50, 51 to a screw conveyer 54 and storage bin 56. The flour is suitable for use as a thickener in soups, liquorice, or as an emulsion binder in sausages, e.g. Bolognas, Frankfurters, Wieners.

Abstract: 1533497 Inorganic dielectric films; SiN, SiO 2  and Si LFE CORP 3 Dec 1976 [17 Dec 1975] 50471/76 Heading C1A [Also in Division H5] A dielectric film of an inorganic substance is deposited on the surface of a substrate 24, disposed in a reaction chamber 10 at a pressure below atmospheric, by activating a first gas dispersed in the chamber via line 40 and feed holes 44 using an RF field generated by coil 16 so as to create a glow discharge zone; a second gas is then introduced downstream of the discharge zone and immediately over the surface of the substrate via holes 36 in the hollow feed 32, 34 and by reaction between the activated first gas and the second gas an inorganic film is deposited. The formation of a silicon nitride film using nitrogen and silicon compounds (e.g. silane) as first and second gases is exemplified. The formation of silica and silicon may be achieved by replacing the nitrogen in the first gas with oxygen or argon respectively. The film may be deposited on a conducting substrate, e.g. Al or Au, a semiconductor, e.g. Si or Ge, or on an insulator, e.g. glass.

A knitted or woven fabric 17 is decatized by first heating the fabric, and then cooling the fabric by refrigerating apparatus comprising an assembly of tubes 104 around which a current of air passes, the air being colled to slightly above 0‹C and then drawn by exhaust means through the fabric 17. The fabric 17 is conveyed through the apparatus by a conveyor belt 16 and passes around conventional decatizing cylinders 2, 2', 2" in a chamber 3, driving rollers 11, 11', 12, 12', 13, 13' being provided. The fabric 17 and the conveyor 16 then pass between hollow plates 118, 118' heated interiorly by steam or electrically to vapourise the treatment liquid on the fabric 17 and conveyor 16. The fabric 17 is then conveyed into a chamber 101 enclosing the refrigerating apparatus comprising tubes 104 through which a fluid flows at a temperature a few degrees above 0‹C. and deflectors 103 to uniformly distribute air introduced through an opening 102. The air is sucked through perforations in a cylinder 105, around which the fabric 17 and the conveyor 16 pass by a pump 108. The fabric 17 then passes around a cylinder 5 to complete the decatizing thereof. In an alternative embodiment, Fig. 2, the fabric is wound around a hollow cylinder 56 having tubular elements 206, 206' coaxial therewith. The element 206 is connected to a pressurised vapour source and treats the fabric along paths I, III, V, VII, IX. Air passes through an intake 202, past baffles 203, past the cooling tubes 204, between vanes 205 of a control valve and is sucked through the fabric along paths II, IV, VI, VIII, X into the element 206' by a suction pump 208. The cooling takes place immediately after the heat treatment.
