Patent GB-868028-A (GB)
Title: Production of sorbic acid
Inventor: JOWITT HUBERT
IPC: C07C51/09
Filed: 1958-10-20
Abstract: Sorbic acid is produced by reacting ketene with crotonaldehyde and healing the product with an aqueous solution of an alkali metal hydroxide (e.g. sodium or potassium hydroxide) to separate solid alkali metal sorbate from the resulting mixture and reacting the separated alkali metal sorbate with an acid having a dissociation constant greater than that of sorbic acid to produce sorbic acid. The reaction of ketene and crotonaldehyde may be effected by mixing at a temperature in the range from 0 DEG  to 60 DEG C., preferably in the presence of catalysts such as halides of boron, or aluminium or other metals, or barium, calcium, mercury, zinc, nickel, cobalt and copper salts of saturated fatty acids, such as acetic, propionic or butyric acids.  The heating of the ketene-crotonaldehyde product is conveniently effected by boiling the mixture of the product and aqueous alkali solution of such a concentration that the alkali metal sorbate is precipitated as a solid and may be filtered or centrifuged off.  The remainder of the mixture may be recycled for a further run of the process.  The alkali metal sorbate may be purified, e.g. by treating a solution thereof with activated carbon, and is then treated with preferably a mineral acid such as hydrochloric acid or sulphuric acid to produce sorbic acid.

Abstract: 1513286 Hydrostatic transmission control CATERPILLAR TRACTOR CO 13 Aug 1975 [26 Aug 1974] 33766/75 Heading F2W In a hydrostatic transmission control system for a motor vehicle wherein a swash plate pump displacement adjusting follow-up servomotor 25 is controlled by a pedal 29 which acts through a linkage 28 and lever 27 on a servo valve spool 46, the lever 27 is pivoted at 30 to a rod 54 which, when the pump output pressure exceeds a predetermined value, moves axially to override the manual control and reduce pump displacement. The servo valve spool 46 is biassed by a spring 88 to a neutral position in which pump displacement is zero. Movement of the servo valve spool 46 meters pressure liquid from an inlet 41 to a chamber 42 containing a servopiston 37 which is integral with a sleeve 38 surrounding the valve spool 46. The piston 37 and sleeve 38 follow the movement of the valve spool 46 and act through a rod 40 to adjust pump displacement. The override rod 54 is normally held in the position shown by a centering spring 55. Pump inlet and outlet pressures are applied to chambers 49, 63 and act directly and through a plunger 60 on a piston 52. When pump output pressure exceeds a predetermined valve the rod 54 moves axially against the bias of the spring 55 and acts through the lever 27 on the servo valve spool 46 to reduce pump displacement. The pump 10 is in closed circuit 11, 12 with a fixed or variable displacement motor 13. In Fig. 3 (not shown) the override control is single acting and responsible to the output pressure of a non- reversible swash-plate pump which supplies the motor through a reversing valve.
Patent GB-337736-A (GB)
Abstract: 337,736. Auer, L. April 24, 1929. Fatty oils; fatty acids.-A process for the preparation of a modified fatty oil or a fatty acid soluble in a selected organic solvent, used in the manufacture of leather cloth, lacquer or varnish, consists in treating the fatty oil with a modifying agent insoluble in the selected solvent, and simultaneously or subsequently heating and dispersing in the fatty oil so treated, more than 2 per cent of a dissoluting promoting agent, which comprises those secondary reagents referred to for example in Specification 321,689, e.g. phenols, or ketones, which are soluble both in the fatty oil and in the selected solvent. Such secondary and dissolution-promoting agents do not per so bring about the desired modification of the physical properties, but only when added to a modifying agent e.g. peroxides, or water-insoluble compounds as described in Specifications 321,690 and 321,725 respectively. For example, by heating linseed oil with a mixture of calcium peroxide and zinc sulphite and dissolving the product in turpentine, a varnish is formed which is too viscous for use. The viscosity is reduced by adding as dissolution-promoting agent, about 4 per cent of o-nitro phenol or benzoic acid (which are soluble in turpentine), to the modifying agents. Such modified fatty oil products may be used as softening agents in the preparation of nitrocotton solutions. For example, up to 30 per cent by weight may be added without flocculating the nitrocotton therefrom. In examples, castor oil is heated with lithium carbonate or sulphite to which p-cresol has been added. The products are soluble in acetone or benzene. The addition of modified linseed oil products improves the ageing properties of the resulting film of lacquer, e.g. linseed oil is treated with sodium bisulphite to which has been added, a-naphthol, pyrogallic acid, p-aminophenol hydrochloride, or cinnamic aldehyde. Specifications 287,943, 289,414, 289,415, 318,562, 321,691, 321,692, 321,722, 321,723, 321,724. 321,726, 337,732; 337,733, [Class 95, Paints &c.], 337,734 and 337,735 also are referred to.

Abstract: 1,041,836. Unipolar transistors. WESTING- HOUSE ELECTRIC CORPORATION. Aug. 27, 1963 [Sept. 10, 1962], No. 33821/63. Heading H1K. A unipolar transistor consists of a semiconductor wafer mainly of one conductivity type with an ohmic contact on one face, and including a series of channels bounded by a network of interconnected zones of the opposite conductivity type at or near the opposite face. Further ohmic contacts are attached to the opposite face and to the interconnected zones. A typical arrangement, Fig. 1, is made by first polishing with powdered alumina one surface of a 20 ohm/cm. P-type silicon wafer, preferably cut from a dendritic crystal, oxidizing it by heating in a mixture of water vapour and argon and selectively removing the oxide to leave an exposed area into which phosphorus is diffused to form an N-type gate region of grating form. The masking oxide is then removed and 20 ohm/cm. P-type silicon epitaxially deposited over the surface from a mixture of silicon tetrachloride and boron trichloride. Finally one corner of the gate region is exposed by etching through wax masking and aluminium evaporated on to form the required ohmic contacts. Alternatively the gate region is formed by epitaxial deposition through a suitable mask. In either case the P-type layer may alternatively be formed over it by acceptor diffusion. Finally when the gate region is formed by diffusion the surface may subsequently be etched to remove low resistivity material and a metal contact evaporated or plated over the whole surface to make ohmic contact to the channel and rectifying contact to the gate region. Such contacts can be obtained by using high work function metals such as gold, platinum, and palladium. If the conductivity types of the wafer and gate are reversed the low work function metals gallium, aluminium and zinc are suitable. Other suitable materials for the wafer, which may be a low resistivity wafer with a high resistivity surface at which the gate is formed, are germanium, A<SP>1</SP> 11 B v  compounds, silicon carbide and cadmium sulphide. Reference has been directed by the Comptroller to Specification 1,010,192.
