Abstract: 450,537. Air - break switches. HENLEY'S TELEGRAPH WORKS CO., Ltd., W. T., 11, Holborn Viaduct, London, and BREEZE, H. W., 132, Wrotham Road, Gravesend. Dec. 18, 1934, No. 36292. [Class 38 (v)] Switches of the kind in which fuses and/or links (fittings) are removably mounted on a carrier which is moved to bring the contact surfaces of the fittings into and out of engagement with fixed contacts, have a carrier comprising a pair of parallel insulating bars, spaced apart and each with switches so disposed thereon as to form pairs, each of which provides for the attachment of a fitting by engaging the contact parts of the fitting which is located transversely of the bars so that its contact parts project beyond the bars for engagement with the fixed contacts. The invention is shown applied to an overhead isolating switch. The carrier comprises a pair of insulating bars 8 secured by bolts 9 and spaced by sleeves 10 so as just to receive the fuses 6 between them, and a link 7 positioned by pins 24. The ends of the link 7 and the contact pieces 13 welded to the fuseend caps extend through notches in the bars 8 into fixed contacts 4, from which they can be separated to open circuit by raising the carrier in its guides 26 by means of rod 27. Contacts 4 and terminals 5 are mounted on insulators 3 on cross-members 11 on a metal frame 1 bolted to the transmission-line support 2. The fuses and link are retained in the notches by means of clips 14, each comprising a plate located against the inside of the bar 8 and turned over at 17 into contact with the front. The plate is cut away to conform to the shape of the notch 12 in the bar 8, thereby forming end pieces 16, of which the turned-over ends 17 form part, and a middle part 15 against which the contact 13 is urged by a spring strip 20. The latter is pivoted to a stud 19 on one end 17 and engages under another stud 18 on the other end 17, the intermediate part being bent into a U 21, 22 bearing on the contact. The resilient nature of 20 permits accommodation of the contacts 4, 13, and prevents the fuse or link falling out. To renew a fuse, the ends 25 of the appropriate strips 20 are depressed to remove locking projections 23 thereon clear of studs 18, and the strips rotated outwards to horizontal position, in which they remain until restored after insertion of a new fuse.

Abstract: 1,133,222. Automatic pressure control. ELLIOTT BROS. (LONDON) Ltd. Aug. 24, 1966 [Aug.27, 1965], No.36879/65. Heading G3R. Fluid-flow associated with a steam generating plant is controlled by a relatively fast acting narrowrange controller and a relatively slow-acting widerange controller, the latter being actuated in response to the position or motion of the former. In Fig.1, the pressure in a boiler furnace 1 is maintained constant by a pressure responsive device 4 which controls a servomotor 6 operating a damper 5 associated with an induced draught fan 2. Regulation is further assisted by causing servomotor 6 to adjust a potentiometer 9 which, through a moving coil unit 14, controls a servomotor 8 adjusting an induction regulator 3 and hence the speed of an A.C. commutator motor driving fan 2. In one modification, a controller of forced draught operates a potentiometer the output of which is applied to moving coil unit 14 through a condenser to give an anticipatory effect. In another modification, in which two dampers and two induced draught fans are controlled, potentiometer 9 is controlled by pressure responsive device 4, instead of servomotor 6, and also in dependence on steam demand. Control of the pitch of fan guide vanes or blades instead of dampers is referred to. A pneumatic link including a force-balance unit may be used instead of potentiometer 9.
Patent GB-811890-A (GB)
Title: Uranium recovery from ores
IPC: C01G43/00
Filed: 1956-12-03
Abstract: Uranium values are recovered from ores containing uranium and calcium carbonate by disintegrating the ore and digesting with an aqueous medium containing free hydrochloric acid.  The slurry so formed, which contains the calcium and the uranium values as chlorides, is extracted with acetone, and the residue is then separated.  The acetone extract may be treated for the recovery of the uranium.  It is advantageous to ensure that the slurry contains calcium chloride corresponding to a calcium carbonate content of 0.4-0.6 per cent. This is adjusted by regulating the amount of hydrochloric acid used, adding calcium chloride if the ore is deficient in calcium carbonate, or blending ores of high calcium carbonate content with ores of low calcium carbonate content.  The water content of the acetone slurry is preferably between 50 and 150 gram of water per litre of acetone. By suitable adjustment of water and calcium chloride content, the desired rapid settling of the residue is obtained so that separation without filtering may be carried out.  Some ores, especially when containing organic carbonaceous material, may be pretreated either by roasting between 450 DEG  and 500 DEG  C., or preferably by adding an oxidizing agent, especially potassium chlorate, to the aqueous hydrochloric acid.  In one form of the invention, the ore is ground, digested with hydrochloric acid, and then opened with concentrated sulphuric acid.  The slurry is dehydrated at 75 DEG  C. and acetone is added.  Water is added, and the acetone solution is separated from the insoluble residue. Anhydrous ammonia is passed into the solution, when ammonium chloride and uranium, iron and vanadium values are precipitated. The acetone is removed and the precipitate is washed with water to remove the ammonium chloride.  The residue is dissolved in sulphuric acid and ammonia is passed in until the pH is about 2, when the iron and vanadium values are precipitated and removed. Aqueous ammonia is now added to a pH of about 7, when the uranium is precipitated as ammonium duiranate, which is removed, washed with aqueous ammonia, and calcined to uranium oxide.

Title: Improvements relating to the production of ketones
IPC: C07C45/26
Filed: 1929-12-03
Abstract: The exothermic manufacture of acetone by the interaction of acetylene and steam at a raised temperature, is combined with the non-exothermic manufacture of acetone and other aliphatic ketones by the action of steam at a raised temperature on aliphatic alcohols having two or more carbon atoms in the molecule, or on the aldehydes, acids, or aliphatic esters derived therefrom, or on mixtures of these substances with one another or with other derivatives of the alcohols or with inert substances, e.g. methyl alcohol or acetate.  The reaction is effected in the presence of catalysts of the kind described in Specification 302,759, [Class 2 (iii), Dyes &c.], i.e. oxygen compounds of heavy metals, particularly of iron, zinc, or nickel, with or without promoters such as aluminium oxide, barium carbonate, lime, or magnesia, or metals, particularly iron; mixed catalysts such as two or more oxides of iron, manganese, uranium, tungsten and molybdenum may also be used, with or without promoters. When the reaction mixture comprises acetylene and ethyl alcohol or its derivatives, such as acetaldehyde, acetic acid, or ethyl acetate, the product is acetone, but mixtures of acetylene with alcohols, aldehydes, &c. having more than two carbon atoms in the molecule, such as n-propanol or butyraldehyde, may yield asymmetric ketones.  A suitable initial material is the residual acetylene, containing uncondensed acetaldehyde and a little water and acetic acid, obtained in the production of acetaldehyde from acetylene.  The reaction temperature lies between 250 and 750 DEG  C., preferably between 400 and 550 DEG  C.  In an example, acetone is produced by passing a mixture of ethyl alcohol vapour, acetylene, and steam at 470 DEG  C. over rusty iron sponge mixed with a little manganese oxide.

Abstract: 370,411. Controlling and indicating furnace conditions. BAILEY METER CO., 1050, Ivanhoe Road, Cleveland, Ohio, U.S.A.-(Assignees of Albright, J. C.; 1079, Quilliams Road, and Junkins, R. D. ; 1082, Allston Road, both in Cleveland Heights, Ohio, U.S.A.) Dec. 30, 1930, No. 39-174. Convention date, Jan. 27. [Class 51 (i).] An indicator for use with a furnace or heating apparatus comprises correlated indices actuated in accordance with two factors, such as steam and air flow, one of the indices being compensated for the disturbing effect of a third factor ; and a furnace control system comprises devices responsive to the steam and air flow factors, means operated by both devices for controlling one of the factors, and means for compensating one of the devices for the effect of the feed water temperature. In the system shown, the steam flow from the boiler is measured by a meter 4 connected to both sides of a constriction 11 in the steam header 1, and comprising an inverted bell 7 operating an indicator 14. The air flow is measured by a meter 16 containing bells 17, 18 subjected to the difference in the pressures existing at openings 24, 25 in the furnace wall, the bells operating a pivoted lever 19 connected to a floating lever 27. A thermometric element 29 in the feed-water supply pipe causes variations in level of the mercury in a U-tube 31, and hence of a float 33 also connected to the floating lever 27, which therefore takes up a position determined both by that of the lever 19 and that of the float 33. The indicator 28 on this lever therefore indicates the air flow with a modification introduced by the temperature of the feedwater. The indicators 14, 28 may, as shown in Fig. 2, be used to give traces on the chart of a recorder, parallel or coincident traces indicating the most efficient relation between the flow of steam and of air, with regard also to the temperature of the feedwater. The draught control mechanism shown comprises a floating lever 46 connected by links at the ends to the levers 8, 27 and intermediately by another link to a pivoted lever 44 which when rocked closes either of two pairs of contacts 42, 43 controlling reve sible motors 37, 40 which respectively operate a flue damper 50 and a rheostat 39 controlling the speed of a motor 38 driving an exhaust draught fan. A pointer 54 on the lever 44 indicates by its movement departure from the correct relationship between steam and air flow.
