Title: Oil and air pressure operated apparatus for automatically opening and shutting mud doors for use in hopper barges
Inventor: WATANABE TOSHIO
IPC: B63B35/30
Filed: 1959-11-02
Abstract: 894,455. Door operating appliances. HAKODATE DOCK KABUSHIKI KAISHA. Nov. 2, 1959, No. 37081/59. Class 65(1). A mud door 1 in a hopper barge is connected by means of a chain or wire 3 to the piston rod 7 of a piston 8 in an oil pressure cylinder 9 so that on release of the door the weight of the mud forces the oil through a non-return check valve 10 and conduit 11 to an air pressure tank 12, the potential energy thus accumulated in the tank being utilized to return the piston 8 to its original position to close the door after discharge of the mud. A manually operated catch means 4 holds the door in its closed position. An auxiliary oil tank 34 is provided so that if insufficient pressure is available in the tank 12 to completely close the door additional oil may be pumped into the cylinder 9 by a pump 20 through a valve 19 and pipe 18, the valve 10 having been closed. The pump 20 may also, if desired, be used to assist the opening movement of the door, oil being pumped from the tank 34 through valve 19 and pipe 22 to the left-hand side of the piston 8. The air pressure in the tank 12 may be increased if necessary by a manually operated compressor 28 or from a motor driven compressor (not shown) through a pipe 27.

Title: Diazotype materials
IPC: G03C1/60
Filed: 1975-09-09
Abstract: The diazo copying material contains a base and a two-component diazo sensitiser arranged on the base. To reduce the loss of resolution capacity due to mutual movement of original/copying material during the preparation of diazo copies from the diazo copying material, an effective quantity of an adhesion-promoting resin is incorporated in the outermost layer which is located on the same side of the base as the diazo sensitiser. The resin is either an aminoplast resin, an epoxide resin or a polyvinyl acetal resin, or a mixture of these resins.

Title: Process for purifying and concentrating fish protein and the products obtained
IPC: A23J1/04
Filed: 1966-08-18
Abstract: In a process for the production of purified and concentrated fish proteins comprising dissolving fish by hydrolysis in alkaline aqueous medium, separating and eliminating lipids and other impurities from the aqueous mass obtained, and concentrating the thus purified aqueous phase obtained by chemical and/or physical methods to provide a product useful as a foodstuff for humans and/or animals, the alkaline hydrolysis is carried out for a period of three hours or less on the raw fish in the liquid medium without a settling stage, so that the resulting liquid mass contains in solution linked lipids still in lipoprotein form undestroyed by the alkaline hydrolysis due to its brevity, which lipoproteins are soluble in water at neutral and alkaline pH; the lipoproteins are precipitated by adjusting the liquid mass to an acid pH lower than 5.5; the precipitated lipoproteins are eliminated by any industrial process for separating and eliminating insoluble solids from a liquid mass; the liquid obtained, free from non-proteic insoluble solids, from free lipids and from lipoproteins is adjusted again to alkaline pH and is subjected to the action of oxidizing agents; and the aqueous liquid thus obtained is adjusted to substantially neutral pH and concentrated.  The hydrolysis may be by sodium hydroxide solution at 40 DEG  to 100 DEG  C.; insolubles may be removed by decantation, pressing, filtration or centrifuging, and emulsified lipids by centrifuging; the pH may be adjusted to between 2.5 and 5.5, and the resulting precipitate separated by decantation, pressing, filtration or centrifuging; the oxidation may be by hydrogen peroxide at 30 DEG to 100 DEG  C. at a pH over 7; the mass may be sterilized by filtration, heating or ionizing radiation; and the protein finally precipitated by adjusting the pH to its isoelectric point, or concentrated by vacuum methods or evaporation. If still liquid it may be spray dried and ground.

Abstract: 925,602. Valves. WESTINGHOUSE AIR BRAKE CO. Nov. 8, 1960 [Nov. 17, 1959], No. 38282/60. Class 135. [Also in Group XXIV] A manual control valve device comprises a casing having a plurality of radial bores 12-17, each containing a valve unit 39-44, Fig. 6, operable to supply or release fluid pressure, a cam ring 74 having an interior cam surface surrounding and co-operating with the units to control all of them simultaneously to obtain varying combinations of supply and release of pressure in the units in a predetermined sequence in response to manual movement of the ring. A rise on the cam moves a roller 63 on a lever 65 to seat a tubular member 54 on valve member 47 to close an exhaust opening and then lifts member 47 away from seat 50 so that pressure fluid at 10, Fig. 7, flows via an outlet, e.g. 8, to a motor. A fall on the cam allows spring 45 to close the supply member 47 and spring 53 to move the end of tubular member 54 away from seating position on member 47 and allow pressure fluid to exhaust from 8 via the inside of member 54 and ports 56 in member 54. The cam ring is rotated by handle 89 pivoted at 91 on a rotatable spigot 92 carried at the centre of the casing and biased by spring 103 to a central position, as viewed in Fig. 7, between two quadrants 105, 106. The handle has a cruciform portion 90, the arms 121-124 of which, Fig. 2, permit the handle to be held against stops 109-120 on the quadrants by rocking and turning on pivots 91, 92, whereby the valve units are operated in nine different combinations to obtain nine different positions of a piston in a cylinder connected to the power transmission of a truck. The piston and cylinder are described in Specification 925,601.

Abstract: Aliphatic ketones or aldehydes, derived from fats and containing more than ten carbon atoms, are converted into emulsified form by mixing with an emulsifying agent, e.g. soap. In examples (1) palmitone is mixed with a highly sulphonated turkey red oil; (2) a mixture of calcium ricinoleate and calcium formate is distilled to obtain crude ricinic aldehyde, which is then emulsified with sodium tetrahydronaphthalene sulphonate.ALSO:Aliphatic ketones or aldehydes, derived from fats and containing more than ten carbon atoms, after being converted into soluble form, are used for the treatment of textiles, e.g. artificial silk, or leather.  The aldehydes or ketones, which are particularly suitable as softening agents, are rendered soluble either by sulphonating with less than the equivalent proportion of sulphuric acid, without the application of heat, or by mixing with an emulsifying agent, e.g. soap.  In examples: (1) palmitone is mixed with a highly sulphonated turkey red oil; (2) a mixture of ketones, prepared by distilling a mixture of calcium oleate and calcium caprate, is treated with the requisite proportion of sulphuric acid, without applying heat; (3) palmitone is condensed by treatment with hydrochloric acid and is sulphonated with sulphuric acid; (4) a mixture of calcium ricinoleate and calcium formate is distilled to obtain crude ricinenic aldehyde, which is then emulsified with sodium tetrahydronaphthalene sulphonate; (5) lauric acid is reduced to the aldehyde and sulphonated with sulphuric acid. Specification 343,098 is referred to.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the sulphonation, generally, of ketones and aldehydes of high molecular weight.  This subject-matter does not appear in the Specification as accepted.
