Title: Improvements in or relating to steam generating and like systems
Inventor: HOWES LIONEL STANLEY
IPC: F22G5/12
Filed: 1961-05-09
Abstract: 1,007,771. Desuperheating steam; spray producers. SUPERHEATER CO. Ltd. May 9, 1962 [May 9, 1961], No. 16878/61. Headings B1R and B2F. [Also in Division F4]  Steam is desuperheated by spraying water at B into a stream main M by an atomizer 3 of the spill back type. Water is delivered by a line W at a predetermined pressure higher than that in the main M, the amount of water passed through the spill line S being regulated by a valve 5 responsive to the temperature of the steam, as measured by a thermocouple 4 in the main M. Three methods of preventing steam passing down the line S are described. In one, as shown, a valve 6 is operated by a control device FD supplied with a signal from a flow-measuring device FM at an orifice plate 7 in the line S and a comparison signal from the constant flow orifice 2 in the line W. In another, Fig. 3 (not shown) control of the valve 6 is dependent on the temperature difference between the lines W and S, and in the third, Fig. 2 (not shown) on the pressure difference between the main M and the line S. Where two superheating stages are employed, the desuperheater is between them, and the thermocouple 4 follows the second stage. The atomizer 3 may comprise the apparatus shown in Fig. 4, in which water enters at A and passes via orifices 12 disposed in circular array to passages 14, see Fig. 5 (not shown), which are tangential to the axis of the device, some of the water exiting through the outlet B and the rest passing through an annular passage 15 and holes 17 to an outlet C leading the line S.

Title: Improvements in or relating to electric motors
IPC: H02K17/04
Filed: 1954-06-09
Abstract: 740,136. Single-phase induction motors. HUTCHINS ELECTRIC CO., Inc. June 9, 1954 [June 15, 1953], No. 16999/54. Class 35. A split-phase motor has a main winding a and auxiliary windings band c on the main and quadrature axes respectively, these auxiliary windings being connected in series and short-circuited for starting purposes. Transformer action between windings a and b causes currents of suitable phase displacement to flow in the windings on the two axes. The supply LI, L2 is connected at points 5 and 15 so that when the short-circuit connection 10 is broken by centrifugal switch 14, all the stator winding acts as the running winding. In a modification (not shown) the supply is connected to points 5 and 7 and a current-responsive relay serves to short-circuit the winding C during starting. Specification 716,453 is referred to.

Abstract: 861,245. Contacting gases with liquids. STERLING INDUSTRIES Ltd. June 3, 1957 [June 1, 1956], No. 17079/56. Addition to 819,574. Class 55 (2). In a gas conditioning device as in the parent Specification in which a wick 4 of sintered metal extends both into a container 3 for a conditioning liquid and also into a flow duct 1 for the gas, the wick 4 may have an enlarged base to enable the intake of the liquid into the wick to be substantially independent of the liquid level in the container 3 or means may be provided to vary the area of the wick 4 which is exposed in the duct 1. The wick 4 is held in a bush 6 screwed at 7 into the wall of the duct 1 and diametrically opposite, a screw-threaded plug 15 is provided which has a bore 16 of such diameter that it fits closely around the protruding end of the wick 4. On screwing the plug 15 into and out of the duct 1, more or less of the wick 4 is covered and the area exposed to the flow of gases is therefore varied. In a modification the wick is adjustable to vary the amount it protrudes into the gas flow duct and the plug, which is solid, may be removed to provide access to the wick.

Title: A method for the manufacture of complex calcium magnesium phosphates capable of being used as fertilizers
IPC: C05B7/00
Filed: 1934-06-11
Abstract: Calcium magnesium phosphates having the formula Ca Mg2 (PO4)2, Ca2 Mg (PO4)2, or CaMgH2(PO4)2 for use as fertilizers are obtained by dissolving a raw phosphate in hydrochloric or nitric acid, precipitating a part of the calcium as sulphate by sodium, potassium, ammonium, or magnesium sulphate, adding the required amount of a soluble magnesium salt other than the sulphate, and precipitating the double salt by addition with agitation of alkali or ammonium hydroxide.  The mother liquors from the precipitation may, according to the acid and salts used, be a solution of sodium, potassium, or ammonium chloride, or nitrate, from which the acid and alkali may be recovered for re-use in the process.  A part of the alkali may be reacted together with carbon dioxide with the separated calcium sulphate to obtain alkali sulphate for re-use and calcium carbonate. An example is given using hydrochloric acid for dissolving the phosphate, sodium sulphate to precipitate calcium sulphate, magnesium chloride as the magnesium salt, and caustic soda as the alkali. Heating to 60 DEG  C. is necessary to precipitate the compounds CaMg2(PO4)2 and Ca2Mg(PO4)2.

Filed: 1934-06-12
Abstract: Beef or mutton are preserved by storing in a chamber in an atmosphere consisting of the products of combustion of a carbonaceous fuel in air and having a composition of 7 per cent or less of oxygen, 10-14 per cent carbon dioxide and the rest nitrogen and other inactive gases, the combustion products being cleaned, humidified approximately to saturation point, cooled to about 3 DEG  F., below a temperature selected from between 35-55 DEG  F., as the prevailing temperature in the storage chamber, and their temperature raised by about 3 DEG  F. prior to entry into the chamber, giving them a relative humidity of about 97 per cent, the gas being passed in a continuous stream through the chamber at a speed which ensures that a relative humidity of about 97 per cent is maintained therein.  Flue gas from a ship's funnel or a chimney stack may be employed after cleaning to remove soot and other suspended matter, e.g. in a scrubber which may also be provided with a supply of sterilic water for humidifying the gas.  The meat may be washed with an isotonic saline solution or with a solution of glycerine before storage. Specification 425,903 is referred to.

Title: Improvements in or relating to the production of ascorbic acid
IPC: C07D307/62
Filed: 1938-06-14
Abstract: 516,115. Ascorbic acid. STEVENS, A. H. (Pfizer & Co., C.). June 14, 1938, No. 17642. [Class 2 (iii)] Laevo-ascorbic acid is produced by dis-. solving 2-keto-laevo-gulonic acid or a readilyhydrolyzable derivative thereof in glacial acetic acid, concentrated phosphoric acid or - concentrated sulphuric acid, adding at least two gram-equivalents per litre of a non-oxidizing .acid stronger than phosphoric acid, and heating. Suitable non-oxidizing acids are hydrochloric, hydrobromic and sulphuric acids. Sulphuric acid can therefore be used for both functions. After the reaction the mineral acid is removed as soon as possible. When acetic - acid is employed as solvent a considerable amount of esterification occurs, and hydrolysis is therefore effected by boiling with alcohols. In examples (1) 2-keto-laevo-gulonic acid is heated to 90-95‹ C. with glacial acetic acid and hydrochloric acid ; diacetone-2-keto-laevogulonic acid 'is heated with (2) glacial acetic acid and hydrochloric acid ; (3) concentrated sulphuric acid and glacial acetic acid ; and (4) concentrated sulphuric acid. After removal of acid, the ascorbic acid is recrystallized from methyl alcohol. Specification 428,815 is referred to.
