Title: Separation of hydrofluoric and hydrochloric acid gases
IPC: C01B7/00
Filed: 1956-05-04
Abstract: Hydrofluoric acid is absorbed from gaseous mixtures containing it, together with hydrochloric acid, by washing such mixtures with a saturated aqueous solution of hydrochloric acid.  The aqueous acid solution may also contain metallic salts soluble therein, e.g. salts of calcium, aluminium, barium, lead, magnesium, or sodium, particularly chloride of calcium or aluminium, when metal fluorides may be formed.  Mixtures of metal salts may be used, and if a mixture of sodium and aluminium is used cryolite is precipitated.  The salts may be added to the acid as aqueous solutions or suspensions, or aqueous solutions or suspensions of the corresponding oxides may be used.  The washing may be at ambient temperature, but preferably 50-100 DEG  C., in countercurrent in an acid-resistant, preferably filled, column, with recycling of the washing acid.  Washing acid may be continuously, or non-continuously, withdrawn from the cycle, and replaced by fresh hydrochloric acid solution containing metal salts, or by water, or aqueous solutions or suspensions of metallic salts or oxides, which immediately become saturated with hydrochloric acid.  A decanter may be provided in the cycle in which metallic fluorides are precipitated.  The hydrochloric acid remaining in the gas may be treated in known manner with water, or dehydrated.  The gas mixture treated may be the anhydrous HCl containing HF evolved in the fluorination by exchange of halogen between HF and a halogenated derivative, e.g. chlorofluoromethanes from CCl4 or CHCl3, chlorofluoroethanes from chlorinated ethane or ethylene, or aluminium fluoride from aluminium chloride.

Abstract: 331,035. Roscoe, A. A. S. May 6, 1929. Supplying consuming devices; starting prime movers.-An internal-combustion engine driving a D.O. generator is started automatically when the load circuit is closed, current then passing from a starting battery D contacts 5, 7 of an electromagnetic switch B, the load, armature C of the generator and thick and thin wire coils of an electromagnetic switch A. Contacts 1, 2 on this switch open the short circuit on the magnets and contacts 3, 4 close the circuit of a starting motor F. When the generator field builds up the circulation of field current through the coil of switch 13 opens the starting battery circuits at contacts 5, 6, 7 and closes the dynamo-load circuit at contacts 8, 9. The thick wire coil of switch A holds the magnet short-circuit open until load is switched off, whereupon the switches A and B return to their original positions and the plant comes to rest. A modification is described in which a solenoid switch, connected between contacts 4, 6, controls an independent circuit for the starter motor and a closing contact on switch A controls a coil-ignition circuit.

Abstract: 1,162,183. Laminates. IMPERIAL CHEMICAL INDUSTRIES Ltd. 25 Jan., 1968 [9 Feb., 1967; 28 March, 1967], No. 6175/67. Heading B5N. [Also in Divisions C2 and C3] Epoxides of the general formula are used as adhesives for the bonding of metal and plastic materials, e.g. steel, aluminium, copper, polypropylene. The materials to be bonded are treated with a mixture comprising the epoxide and optionally a catalyst, or are alternatively treated with two separate coatings, one of epoxide and one of catalyst. The treated materials are then held in contact, and heated, until a bond is formed. Suitable catalysts, if required, are basic catalysts, Friedel-Crafts catalysts, or peroxides. An example is given of how 3-(3,4-dihydro-2H-pyran-2-methylamino)- 1,2-epoxypropane is used to bond together steel strips, using no catalyst; aluminium/ aluminium or copper/copper or polypropylene/ polypropylene strips using triethylamine as catalyst; steel/steel, aluminium/aluminium or copper/copper strips using boron trifluoride etherate as catalyst; and aluminium strips using cumene hydroperoxide. In each case the heating is for 16 hours at 130 C. The copper and steel strips may first be prepared by immersing in an aqueous acid potassium dichromate bath for ten minutes at 20 C.

Title: Fuel element bundle for nuclear reactors
IPC: G21C3/322
Filed: 1967-03-29
Abstract: 1,146,779. Fuel elements. KERNFORSCHUNG FUER G.m.b.H. 29 March, 1967 [2 April, 1966], No. 14202/67. Heading G6C. A fuel element bundle comprising a plurality of rod-shaped fuel elements surrounded by a coolant conducting canning tube shows sectors of differential flow resistance when viewed in the axial direction, these sectors extending helically relative to the longitudinal axis of the fuel element bundle. The fuel elements in the sectors of high flow resistance are at a small distance from each other while the sectors of low flow resistance have either fuel elements at a large distance from each other or no fuel elements at all. The transition in the axial direction from one type of sector to the other is effected by means of offsets at intervals along the elements. The strongest deformations exist in the marginal areas of the sectors. The result is a helical coolant flow through the fuel element bundle resulting in temperature equalization and a corresponding reduction in distortion and thermal stresses. In a particular embodiment, the pitch of the sectors decreases in the direction of flow of the coolant.

Title: Improvements in aeroplane wings with internal pressure and elastic interados
IPC: B64C3/46
Filed: 1928-05-16
Abstract: 292,907. Soc. Anon. des Ateliers d'Aviation L. Breguet. June 25, 1927, [Convention date]. Planes and wings, construction of; steering and balancing.-An aircraft wing is formed with a rigid leading edge and upper surface and with a flexible wall on its lower surface which is subject to deformation by pressure produced by the relative wind. The internal pressure varies automatically in accordance with the incidence and in some instances may be positively controlled for manoeuvring purposes. In the form shown a flexible cover 2 of canvas or rubber encloses a space 3 which is maintained under pressure by air conduits 4 leading to holes 4a on the upper part of the leading edge. The position of the holes and direction of the conduits are so chosen that the camber of the plane is biconvex at small angles of incidence, plano-convex at normal incidence and concavo-convex at large angles of incidence. The pressure may be applied to the flexible covering by a series of separate sacks attached to the ribs and connected bv tubes to the holes 4<a>. The wing may be divided into compartments and the holes 4<a> or the conduits 4 corresponding to each compartment may be controlled by valves to produce changes of contour either equally or differentially on the two sides of the machine, or the inclination of the air conduits to the wind may be changed. The invention is stated to be applicable also to rotatable planes and to bodies or hulls. According to the Specification as open to inspection under Sect. 91 (3) (a) elastic walls may be placed on both faces of the wing. The internal pressure may be varied by an air blower or by exhaust gases. This subject-matter does not appear in the Specification as accepted.

Abstract: 561,024. Jacks. HURST, W. F. F. MARTIN-, and BRITISH THERMOSTAT CO., Ltd. Oct. 16, 1942, No. 14524. [Class 78 (iii)] An electrically controlled fluid pressure operated jack comprises a telescopic ram 3, 4 normally extended by a spring 14. Fig. 2 shows a form adapted for pneumatic operation; in which the admission and exhaust valves 35, 32 are controlled by a spring-biassed magnetic core 22 influenced by a solenoid coil 20. The admission plug 33 connects by a duct 34, valve passage 35, duct 37 and annular chamber 38 to a passage 12 around the cylinder 6 and a port 13 leading into the cylinder below the piston 7. When the pull is completed, the solenoid is de-energized so that the spring 23 can move the core 22 to close valve 35 and open valve 32. The air then escapes by way of port 13, passage 12, annulus 38, duct 37, valve duct 31 and orifice 42 to the atmosphere. In a form for hydraulic operation, the core 22 slides a piston valve in its ported'sheath to connect the cylinder 6 either with the admission plug 33 or with a radial exhaust nozzle. The jack is stated to be applicable to the actuation of a two-speed supercharger for an aircraft engine, under the control of an altitude or like operated switch. In both forms the spring abutments and the location of port 13 may be such as to make the collapsed disposition the normal one.
