Abstract: 1,098,885. Heating steam boilers by steam. BABCOCK & WILCOX Ltd. [April 15, 1965, [April 17, 1964], No. 16118/64. Heading F4A. Steam generating plant comprises a low pressure boiler 4 heated by high pressure steam from the steam and water drum 1 of a high-pressure boiler, there being valve means 7 to control the rate of flow of high pressure steam in response to the demand on the low pressure boiler, 4. The high pressure steam from line 2 condenses in the horizontal U-tubes 3 of the low pressure boiler 4 and is returned through line 5. The low pressure steam so generated for use in oil burners or soot blowers is delivered through ducts 6 and is superheated if needed. The valve 7, situated in line 2 or return line 5 responds under the action of device 8 to changes in low pressure boiler steam pressure and/or rate of flow. A main turbine 12 may be connected in parallel with the low pressure boiler.

Abstract: 1,243,457. Anthraquinone dyestuffs. SANDOZ Ltd. 28 March, 1969 [8 April, 1968; 31 May, 1968; 30 Sept., 1968], No. 16476/69. Heading C4P. The invention comprises anthraquinone dyestuffs of the general formula wherein A, is a 1-amino-anthraquinonyl-4- radical optionally substituted in the 1-amino group, optionally substituted in the 2-position by a sulphonic acid group or an etherified hydroxy or thio group and substituted in the 6- and 7-positions by hydrogen, F, Cl, Br, or a sulphonic acid group. They are prepared by (1) reacting a l-amino-4-halogeno-anthraquinone with 3,5,5-trimethyl-cyclohexylamine and subsequently converting any 2-bromo-substituents to 2-S0 3 H by reaction with a watersoluble neutral sulphite or optionally sulphonating with sulphur trioxide or an agent yielding sulphur trioxide to form a 2-SO 3 H group. The amination' reaction takes place at 40-220‹ C. in aqueous or aqueous organic medium for watersoluble 'anthraquinone compounds and in an organic medium for water-insoluble anthraquinone compounds. When the anthraquinone starting material bears a 1-aralkylamino- or 1 -cyclohexylamino group this may be acylated prior to condensation with 3,5,5-trimethylcyclohexylamine and subsequently hydrolysed. They may be prepared by (2) reacting a 1- halogeno - 4 - (3,5,5 - trimethyl) - anilinoanthraquinone with an amine and then, if the amine contains no SO 3 H . group, sulphonating the product with sulphur trioxide or an agentyielding sulphur trioxide. They may be prepared by (3) reacting a l-amino-4-(3,5,5-trimethyl)-anilino anthraquinone with a halogeno aliphatic or aromatic compound or with benzyl alcohol, or alternatively with an xunsaturated aliphatic carboxylic acid or a halogenoacetic acid and then with an amine to form the acid amide in presence of an inorganic acid halide, the products then being reacted with sulphur trioxide or an agent yielding sulphur trioxide. They may be prepared by (4) reacting 1,4-dihydroxyanthraquinone 6- or 7-sulphonic acid with 1 mole of 3,5,5-trimethylcyclohexylamine and 1 mole of an amine or by aminating a l-halogeno-4-(3,5,5-trimethyl)- anilino - 6 - (or 7) anthraquinone sulphonic acid. They may be prepared by (5) reacting mole of an 1-amino-2-bromo or sulpho-4-halogenoanthraquinone with 1 mole of 3,5,5-trimethylcyclohexylainine and the product with 1 mole of an aliphatic or aromatic hydroxy or mercapto compound, the product being reacted with sulphur trioxide or an agent yielding sulphur trioxide. The dyestuffs are used to dye, pad or print wool, silk, hair, leather and synthetic polyamides and polyurethanes.

Abstract: 641,960. Electrolysis. LAWARREE, H. June 24, 1947, No. 16656. Convention date, June 25, 1946. [Class 41] An electrolyser for refining or recovering pure metals from scrap of the kind in which the scrap, forming a soluble anode, is contained in a basket inert to the electrolyte, is provided with one or more supports or bases of insulating material also inert as regards the electrolyte and which has smooth surfaces so inclined that the metal scrap slides over these surfaces towards the outer vertical walls of the basket and with a screen or diaphragm whose electrical resistance in the path of the electrolysing current decreases progressively from top to bottom inserted between the scrap metal anode and the cathode. As shown, the base 8 is constituted, e.g. of a porcelain cone or of glass plates and the current is fed to the scrap metal anode 6 through a sheet 11 consisting of such metal that salts formed by the action thereon of the electrolyte are soluble in the electrolyte; e.g. the sheet 11 may be of copper or aluminium when employing an acid copper sulphate bath for refining copper. A weight 12 is mounted on the sheet 11 to ensure good contact between the sheet and the scrap metal anode 6. The walls 3 of the basket. are preferably lined with a screen 5 of insulating material which is proof against attack by the electrolyte. The screen or diaphragm 10, the electrical resistance of which decreases progressively from top to bottom may comprise, for example, two layers of acid-resisting filter cloth sandwiched between three layers of perforated celluloid sheet of different lengths, the lateral edges of the outer sheets being stuck together by means of acetone.

Abstract: 545,533. Sole-laying presses. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). Nov. 29, 1940. No. 17047. [Class 17 (i)] Sole-laying presses of the kind described in Specification 408,953 are provided with additional gauging members for a wedge heel between the shoe and sole. The shoe and sole gauges for the toe end are elongated, so that they may be used for a large range of sizes. The rear gauges are carried on a vertical slide and urged upwardly by a spring 50. A clamping nut 54 allows all the rear gauges to be adjusted longitudinally of the shoe. The heel end of the sole is positioned with the aid of a gauge 66 formed with a V-shaped recess for engaging the heel. The wedge heel W is positioned with the aid of side gauges 84, 86 independently adjustable in respect of the sole gauges 80, 82 at the same vicinity, the gauges on the two sides being carried by arms 76, 78 geared together. The arm 76 is adjustable by a screw 94 and opposing spring 92 to cause the gauges to contact with the work at the same time on the two sides of the shoe. The gauges are swung toward and from the shoe by an inclined slot co-operating with a roll. A wedge heel gauge 96 may be advanced and retracted by a screw 102. The gauge is carried on a slide urged upwardly by a spring so that it may yield downwardly as pressure is exerted on the work. A screw 126 adjusts this gauge laterally. The heel end of the shoe has a pair of gauges 140 of substantial height, adjustable laterally by a handle 144 and carried on arms geared together, and actuated by a roll 152 on one of the arms engaging a slot in a slide connected to the swinging frame described m the prior Specification. In a modification, for use when the wedge heel is stapled to the shoe, the rear shoe gauge and the forward wedge heel gauges are omitted and the rear wedge heel gauge is pivoted on a transverse horizontal axis so that it can yield downwardly against a spring.

Abstract: 1,135,239. Microwave processing of food. CRYODRY CORP. 19 April, 1966, No. 17079/66 Headings A2A and A2D. [Also in Division H5] Food passing through a conductor walled tunnel is heated with microwave energy while maintaining an electrically non- conductive partial covering around the food to reduce the evaporation of moisture therefrom. In one embodiment, food enclosed in partially sealed plastics pouches is passed through a microwave oven of the type described in Specification 1,043,290. Immediately after processing, the pouches are passed through a vacuum chamber to rapidly cool the food and are then completely sealed and frozen for storage. In another embodiment, Fig. 2, the tunnel 12 of the oven carries additionally a long cover 37 of dielectric material, the conveyer belt 17 of the oven being formed of a porous dielectric material such as glass fibre cloth or a perforated plastics material. In a further embodiment, Fig. 4, the sides of the lower run of a porous dielectric conveyer belt 47 are guided upwards, and the sides of the upper run of the belt 46 are guided downwards, by rollers 52 during passage through the tunnel 12<SP>1</SP> of the oven to substantially complete the enclosure of the food. The two runs of the conveyer belt 46, 47 are spaced apart at the entrance and exit ends of the oven to provide access for loading and unloading. The latter two embodiments of the oven also include a sloping floor 14, 14<SP>1</SP> leading to a drain 16. The process may be used for blanching or sterilizing foods such as fish, chicken, bread rolls, spinach, and broccoli, or for cooking foods.
