Title: Process for the saccharification of cellulose-containing material
Inventor: KUSAMA JUN
IPC: C13K1/02
Filed: 1961-01-04
Abstract: In saccharifying particulate cellulose-containing material by the hydrogen chloride gas-suspension method, there is added to the cellulose-containing material a non-tacky substance which is inert under the reaction conditions, has an average particle size less than that of the cellulose-containing material and is dry or has a water content such that its water vapour pressure is less than that of the ambient atmosphere. The suspension may be effected by fluidizing in hydrochloric acid gas, by entraining in a flow of hydrochloric acid gas, or by mechanical stirring. Examples are of impregnating 10 kg. of beechwood chips treated with hydrochloric acid to remove hemicellulose and of average particle size 0.5 mm., or such beechwood chips untreated, with sufficient aqueous hydrochloric acid to provide 6 kg. of water, mixing in 1 kg. of pure lignin, industrial cellulose-containing lignin or diatomaceous earth of particle size less than 0.1 mm., placing the mixture in a column, passing cooled hydrochloric acid gas upwards to fluidize the mixture and, while maintaining fluidization, passing heated hydrochloric acid gas upwards to provide a temperature of 40-50 DEG C. until hydrolysis is 95% complete.  Other examples are of passing wheat straw cut into 1 mm. lengths and impregnated with aqueous hydrochloric acid at 100 DEG C., cut wheat straw not so treated, acid-treated or untreated beechwood, sawdust or bagasse, disintegrated waste paper or disintegrated rag through a cooled glass tube by a high speed flow of hydrochloric acid gas to which diatomaceous earth, pure lignin, industrial cellulose-containing lignin, coke powder, charcoal powder, carbon black, acid-treated peat powder, dry clay, fine sand, brick powder or glass powder of particle size less than 0.1 mm. has been added, and then passing the mixture through a tube for hydrolysis at 45 DEG C. by a high speed flow of hydrochloric acid gas.

In a method of making a printed circuit assembly, a plurality of conductors is provided on at least one surface of a glass substrate, and glass having a lower melting point than the glass of the substrate is flowed on said surface(s) to provide an adherent insulating coating thereon covering said conductors. As shown, a thin film magnetic memory store comprises a glass substrate 1 on one surface of which parallel address conductors 2 are formed, as by evaporation; terminal portions 9 may be provided as described in Specification 970,705. This one surface is coated with a powdered glass composition having a lower melting point than the glass of substrate 1, and heat is applied to melt the glass powder, which flows to form a layer 3, the surface of which may be ground and polished. A plurality of sense conductors 4 and digit conductors 7 is formed on the surface of the layer 3 after which a further layer 5 is formed on the latter surface by melting and flowing thereon glass powder having a lower melting point than that of layer 3. Layer 5 may be ground and polished, then magnetic elements 6 are disposed, as by vacuum evaporation, on the layer 5; elements 6 may be circular, elliptical, or rectangular, and may comprise elemental areas of a continuous thin magnetizablo film. A similar assembly of glass layers and address, sense, and digital conductors may be provided in mirror-image fashion on the layer 5, either by forming a separate assembly or by continuing to build coatings of glass and conductors on the original assembly. Preferably the memory store is protected between plates of, e.g. resin; a plurality of stores may be supported together in a pile. In some cases the sense and digit conductors may be commoned; in others, each sense conductor may be interposed between two digit conductors. The conductors are of copper or of aluminium, silver, or gold. When connection is required between conductors of different layers, an opening is left in the relevant glass layer by the use of a mask or resist material, the connection then being printed on, as by evaporation. Specification 1,004,456 also is referred to.

Filed: 1921-01-06
Abstract: 156,612. Saunders, A. T. July 2, 1917, [Convention date]. Void [Published under Sect. 91 of the Act]. Printing in several colours; processes, special.- To make coloured motion picture. films the individual pictures of an ordinary black and white film are enlarged in turn upon a roll or separate pieces of art paper and coloured representations made by hand of parts to be coloured in a particular colour from which colour printing surfaces are made to colour the black and white film. Three sets of projections are used to obtain the colour printing surfaces by photographic reduction to the scale of the original film. Collotype or flexible zinc printing surfaces may be used, or half tone processes, but in the latter case the position of the half tone screen is shifted periodically to avoid a visible screen effect. Printing inks of the dye or water colour and gum type may be used. The taking of ink by the picture film may be facilitated by moistening the picture film. The picture film to be coloured is preferably made less dense in the shadows than usual for monochrome films. When the film subject includes highly coloured costumes, colours having a high actinic value should be used. When there is no movement of a portion of the subject corresponding to a particular colour in a series of pictures, a single enlarged representation of this will serve for the whole of the series. Fig. 1 illustrates an enlarging apparatus in which the picture film 3 is enlarged upon a wide roll of paper 12 fed synchronously with the film. This may alternatively be moved behind a translucent glass surface and coloured from the back. Fig. 9 illustrates a printing apparatus for printing from a film 3a which passes from a roll 24 immersed in a damping tank 30, between blotting rollers 26, between inking rollers 27 and pressing rollers 26a, thence into contact with the picture film 3 under pressure from a roll 22 and finally is wound on the roll 29. The picture film and printing film are fed together by the sprocket 21 and the picture is wound spirally on a drum 23.
