Abstract: 628,321. Steam superheaters; air and gas heaters &c BABCOCK & WILCOX CO. June 21, 1945, No. 15845. Convention date, July 4, 1944. [Classes 64(i) and 123(iii)] [Also in Group XXX] Fluid heating apparatus, e.g. a steam superheater or an air or fuel gas heater, comprises a pair of fluid heaters A, B in each of which fluent refractory heat transfer material is passed successively through an upper chamber 12 and a lower chamber 13 in which it is respectively heated and cooled by contact with heating and cooling fluids passing through those chambers, the fluid heated in the lower chamber of one heater A taking part in combustion to produce the heating gases supplied to the upper chamber of the second heater B. Air or fuel gas may be heated in the first heater A and supplied through the pipe 44 to burners 29 in the combustion chamber of the heater B, which may be used to superheat steam or heat air or fuel gas. A series of more than two heaters may be used, each except the last heating fuel or air for combustion in the next heater. Alternatively, both fuel and air may be heated in two such heaters for combustion in a third. In each heater the two chambers 12, 13 are connected by a throat 14 surrounded by an annular chamber 43 into which the heated fluid from the lower chamber flows through a ring of slots 40. An annular combustion chamber 25 surrounds the upper chamber 12. Discharge of the refractory material from the lower-chamber without substantial leakage of fluid is controlled by vertically reciprocating valves (see Group XXX). The material is returned by an elevator 88 to a pipe 16 discharging into the upper chamber 12. Dust mixed with this material can be entrained by hot gases flowing from the chamber 12 through the pipe 20 leading to a cyclone separator 98. A separate hot gas outlet 17 is also provided.

Title: Improvements in and relating to electric power cable
IPC: H01B7/29
Filed: 1946-05-25
Abstract: 612,482. Electric cables. SONNENFELD, H. May 25, 1946, No. 15892. [Class 36] [Also in Group XXXVII] An electric cable is constructed in such a manner that the heat generated by the passage of current along the conductor may be converted into useful energy. For this purpose a cooling fluid is allowed to circulate in the cable, either in the hollow core of the conductors, o cooling tubes may be arranged between the conductors in a cable duct. The latter arrangement is shown in Fig. 2, with the cooling tubes 5 arranged between cores 2 within the duct 1. A refrigerant circulates in the pipes 5 and is pumped into compressor 8. Thence it flows to a condenser 10 giving up its heat to liquid 11 for a heating system, and on to expansion valve 9, and back to pipes 5. The operation of the compressor 8 is controlled by the current flowing in the cable, thus ensuring that the cable temperature is kept constant. One method of doing this is shown. The primary of the transformer 12 is traversed by the cable current and the current in the secondary operates the core of the solenoid 14 which varies the rheostat 19 via the cam 16. The rheostat 19 is in the field circuit of a motor 20 driving the compressor 8. A heat storage system is incorporated to ensure that the heat circulating by means of the medium 11 does not vary unduly during peak loading periods of the cable. Specification 393,292 is referred to.

Title: Quaternary ammonium compounds
IPC: C07C233/00
Filed: 1954-06-02
Abstract: The invention comprises quaternary ammonium compounds of the general formula <FORM:0756706/IV(a)/1> wherein A is a phenyl radical substituted by from one to three halogen atoms or alkoxy groups of one to four carbon atoms, the substituents being the same or different when more than one is present, A is a straight or branched chain alkylene radical, containing from two to five carbon atoms, in which the free valencies are on different carbon atoms, N=B is a tertiary amino radical, n is an integer from 0 to 6, the group CnH2n being straight or branched, and X is an anion, preferably a chloride, bromide or iodide ion.  The expression "tertiary amino" includes dialkylamino with the same or different alkyl radicals containing from one to six carbon atoms, and saturated heterocyclic groups such as 1-piperidyl, 1-pyrrolidyl, 4-morpholinyl and lower-alkylated derivatives thereof.  The invention also comprises the preparation of the above compounds by reacting at least 2 mols. of an aralkyl halide ArCH2Hal with one mol. of the appropriate N,N1 - bis(tertiary aminoalkyl)-dicarboxylic acid amide.  The reaction takes place slowly at room temperature but application of heat is preferred and an inert solvent can be used.  The halides so formed can be converted to any desired salt by treating them with silver oxide to produce the corresponding quaternary ammonium hydroxide and then neutralizing this with the appropriate acid.  In examples, N,N1 - bis(2 - diethylaminoethyl) oxamide is prepared from ethyl oxalate and 2-diethylaminoethylamine and is then converted into the corresponding quaternary chlorides containing the following radicals Ar:-4-methoxy-, 4-chloro-, 3,4-dichloro-, 2-chloro-and 2-methoxy-phenyl.  The following substituted amides are prepared similarly and are then reacted with 2-chlorobenzyl chloride to give the corresponding quaternary chlorides:-N,N1-bis(3 - diethylaminopropyl) - oxamide, N,N1-bis(2 - diethylaminoethyl) - succinamide, N,N1-bis(2 - diethylaminoethyl)-adipamide and the corresponding malonamide, N,N1-bis(3-diethylaminopropyl) - malonamide, N,N1 - bis(2 - dimethylaminoethyl) - oxamide, N,N1 - bis(2-diethylaminoethyl) - suberamide, N,N1 - bis(2-dipropylaminoethyl) - oxamide and N,N1-bis-[2 - (1 - piperidyl) ethyl] - alpha - ethylmalonamide.  The following quaternary salts are also prepared:-N,N1 - bis(2 - diethylaminoethyl)-oxamide bis(2 - bromobenzochloride), N,N1-bis-(2 - dimethylaminopropyl) - oxamide bis(3-methoxybenzochloride), N,N1 - bis[2 - (1 - pyrrolidyl ethyl] - glutaramide bis(2 - chloro - 4 - ethoxybenzochloride), and N,N1 - bis[5 - (4 - morpholinyl) pentyl] - oxamide bis(4 - fluorobenzochloride).  The preparation of the acetate, nitrate, sulphates, phosphates, lactate, tartrates and citrates from N,N1-bis(2-diethylaminoethyl) - oxamide bis(2 - chlorobenzochloride) is also described.  The radical Ar may also contain iodine atoms in addition to those specifically referred to above.
Patent GB-612591-A (GB)
Title: Corrosion inhibiting lubricating or other oil or grease
Filed: 1946-05-29
Abstract: Lubricating or other oils and greases for protecting iron and steel against rusting and corrosion and motor fuels (particularly those containing ethyl alcohol) are characterised by the presence of a nitro-phenate having one or more nitro groups in the molecule.  The nitro-phenate may be a salt of dinitrophenol, of nitrocresol, or of nitrothymol, and the salt metal may be an alkali metal, particularly lithium.  The nitrophenate may have an aliphatic side chain or chains, each having at most 5 carbon atoms, and may be dissolved in an oil-soluble organic solvent such as amyl alcohol or acetate before being added to the oil or lubricating grease.  In an example, about one part by weight of sodium dinitrophenate is dissolved in 100 parts by weight of amyl alcohol and about one part by weight of this solution is added to 10 parts by weight of oil.  It is stated that this composition prevents the rusting of ball-bearing steel, even when water has been added to the oil.  The oils whose corrosion inhibiting efficiency may be improved by the addition of nitro-phenates include fuel oils, and vegetable drying oils.  The corrosion of ferrous metal tanks by motor fuels containing ethyl alcohol is inhibited by the addition of 0.01 to 0.5 per cent by weight of a nitro-phenate.  Alkali and other salts of dinitrocresol, e.g. Li p  2-methyl-4,6-dinitro-phenol and Li 4-methyl-2,6-dinitro-phenol, and lithium or other alkali metal salts of mono-, di-, and tri-nitro-thymol are referred to.

Filed: 1944-08-30
Abstract: 588,617. Dielectric heating. BRITISH INSULATED CABLES, Ltd., QUAYLE, J. C., JONES, P., and MILLS, E. W. Aug. 30, 1944, No. 16470. [Class 39 (iii)] [Also in Groups V and XXX] In apparatus for producing long lengths of cellular thermoplastic or thermosetting material, the material containing a blowing agent is passed through a high frequency electric field by travelling belts forming the walls of a passage which increases in cross-section in the direction of travel. At least one of the electrodes which induces the electric field, comprises one or more of the belts. In one example, thermoplastic materials are expanded in a passage formed by an earthed metal belt 1 passing over pulleys 2a, 2b, insulating side belts, as at 34, mounted on pulleys 30, 31, and upper belts 7, 28 comprising insulating ribs with conductive coat-' ings or embedded conductive layers which are coupled successively by electrodes 25 and 25a to separate high frequency sources, whereby the heating intensity can be varied along the passage beneath each belt. The belt 7 passes over pulleys 8 carried by frame 13 resiliently mounted on pillars 16 with means for adjusting the height of the belt 7. The belt 28 is similarly mounted and forms a continuation of the passage of increased height and length in which the material expands before passing to a cooling zone formed by the side and bottom belts, on to the backs of which cold air is directed by nozzles 36. In another example, the height of the passage increases gradually. Each upper belt comprises an earthed metal strip. The bottom belt is of the construction for the upper belts in Fig. 1 with similar electric coupling means. For additional control of the expansion of the material, the apparatus is enclosed in a chamber filled with gas under pressure. The material enters and leaves the chamber through sealing means. In a modification, the belts form a circular passage. A conductive core of the material may constitute one of the electrodes. For thermosetting materials, the cooling zone is replaced by a further heating zone including an upper belt.
