Title: Improvements in rotary furnaces
Inventor: BEETZ PIERRE
IPC: F27B7/08
Filed: 1952-01-29
Abstract: 703,035. Rotary furnaces. INDUSTRIAL & FINANCIAL ASSOCIATION, Inc. Jan. 29, 1952, No. 2367/52. Class 51 (2) Unequal expansion between the metal casing and the refractory lining of an externally heated rotary furnace for remelting metals is compensated for by forming the casing of spaced bars connected between end plates, and arranging a resilient connection between one end plate and the refractory lining. In the preferred embodiment, the refractory lining 5 is built up of tongue-and-groove blocks, the metal casing comprises peripherally spaced bars 4 extending between end plates 2 and 3, and the resilient connection comprises a movable plate 13 resiliently pressed against the lining 5 by push rods 14 extending freely through the end plate 2 and subjected to the action of springs 15 interposed between abutments on the push rods and members 16 connected rigidly to the end plate 2 by tie bolts 17. The tie bolts have screwed ends passing through the members 16 and provided with nuts whereby the pressure of the springs 15 can be adjusted. The end plates 2 and 3 carry trunnions 7 and 8 supported in bearings on fixed supports 11 and 12 respectively and cavities 6 between the end walls of the lining 5 and the plate 13 and end plate 3 respectively are filled with insulating material, e.g. asbestos.

Title: Improvements in engine starting mechanism
IPC: F02N15/06
Filed: 1932-01-26
Abstract: 393,357. Turning-gear. ECLIPSE MACHINE CO., Elmira, New York, U.S.A. Jan. 26, 1932, No. 2374. Convention date, Jan. 29, 1931. [Class 7 (v).] In an engine starter in which the pinion 11 is moved axially into engagement with the engine gear 15 by the relative rotation of two sets of inter-threaded helical springs 13, 14, the ends 24 of which engage axial slots 23, 36 in the pinion and in a collar 16 secured to the starter shaft 10, radial and longitudinal movements of the springs from the slots are prevented by thimbles 26, 37 surrounding the pinion hub 22 and the collar 16. As shown, the thimbles are each provided with a flange 27 having a central opening to fit loosely the shaft 10, and radial slots 29 traversed by the ends of the springs. The slots 29 are formed by bending outwardly curved arms 31, which form shoulders 32 serving as abutments for the ends of the springs, while the arms 31 bear against the outside of the bent parts of the springs. The thimble 26 is secured in place by turning over the edge 34, which is provided with slits so that the turnedover edge forms shoulders bearing against the ends 24 of the springs on the opposite sides from the arms 31, locking the thimble against rotation. The pinion is normally held in the disengaged position by a light spring 38 between the pinion and a thrust collar 19 on the shaft 10. The pinion may be fitted with a heavy rim 40, the inertia of which facilitates the axial movement of the pinion.

Title: Improvements in electrical transformers
IPC: H01F38/10
Filed: 1941-02-25
Abstract: 544,997. Transformers ; supply systems for discharge lamps. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 25, 1941, No. 2552. Convention date, Feb. 29, 1940. [Classes 38 (ii) and 38 (iv)] An arrangement for supplying a pair of discharge lamps 44, 45 comprises an auto-transformer winding 10 surrounding the central part of a core leg 14 the ends of which carry re-actance coils 11, 12, the leg 14 being held in position by magnetic members 23-26 which form in conjunction with the outer core structure 18 a complete magnetic circuit for the transformer flux and magnetic circuits for the flux of the reactance coils which include air gaps 31, 32. The coil 11 is connected in series with the lamp 44 which operates with a lagging power factor, whilst the coil 12 which is of smaller dimensions is connected in series with the lamp 45 through a condenser 55 so that lamp 45 operates with a leading power factor. Thus the resultant power factor may be made unity, and the effect of light flicker is reduced due to phase displacement of current in the two lamp circuits.

Title: Coupling for a fluid flow system
IPC: F16L29/02
Filed: 1959-01-23
Abstract: 842,260. Pipe couplings. TRELEMAN, L. M. Jan. 23, 1959 [Feb. 5, 1958], No. 2583/59. Class 99(1). A coupling for a fluid-flow system comprises a tubular valve housing 12, 17 a valve 20 in the housing and means for holding the valve normally closed, a tubular body 37 coaxial with the housing and axially spaced therefrom, and a tubular actuator 45 coaxial with the body and slidable therein so as to be extensible from the body towards the housing while retaining a fluid-tight seal with the body. There is means to prevent relative rotation between the actuator and the body, co-operating sealing means engageable together to provide a fluidtight seal between the actuator and housing when the former is extended from the body, whereby a fluid-tight connection is made through the actuator from the body to the housing without the necessity of relative axial movement of the body and housing, and means 48 on the actuator for forcing the valve to open as the actuator becomes fully extended from the body. For extending the actuator from the body there is a screw-threaded coupling comprising a part 53 having an external thread and secured to the actuator and an internally threaded sleeve 32 surrounding the housing and rotatable and axially movable relative to the housing to extend beyond the latter towards the body, the body having an abutment 41 against which the sleeve engages when screwed on to the part 53 so that rotation of the sleeve draws the actuator towards the housing ; an abutment 56 on the housing limits movement of the actuator towards the housing. As shown, the valve housing consists of the parts 12, 17 in screw-threaded engagement, locked together by a circlip 24, and sealed by an O ring 29 and the tubular valve actuator 45 which is slidable in the body 37 has stub splines 47 co-operating with internal, axial splines 38 of the body and is sealed to the latter by an 0 ring 44. In coupling the parts 37 and 12, 17 by screwing the sleeve 32 onto the part 53, the cross-bar 48 on the actuator 45 engages the valve 20 to move the latter from a seat 19 and against the pressure exerted by a spring 23, the actuator being sealed with the housing by an 0 ring 31.

Anthracene; carbazole; naphthalene; phthalic anhydride; anthraquinone; benzoic acid; salicylic acid.-Sublimable organic substances are separated from mixtures containing them by wholly or partly vaporizing the mixtures in a current of inert gas, and progressively cooling the gas to condense the vapours fractionally. A vaporizer 1, through which a current of gas, such as air, purified flue gas, carbon dioxide, nitrogen, water gas, hydrogen, natural gas from petroleum wells, &c., is forced by a pump 3, is heated by gas burners 5 or otherwise. The vapours are carried through a series of chambers 7 - - 12 separated by wiregauze screens 13 - - 17. Cooling-water may be applied to the outside of the chambers by pipes. 29 - - 34. Weights 24 - - 28 are knocked against the screens to shake off the condensed substances. The gas from the last chamber may be returned to the pump and heated, if desired, by gas burners 37. The process is applicable for the separation of anthracene, phenanthrene, and methyl anthracene from crude anthracene press-cake, the carbazole being retained in the residue by preliminary treatment with caustic alkali, for the separation of phthalic anhydride from naphthalene, for the purification of crude anthraquinone and crude naphthalene, and for the separation of benzoic acid and salicylic acids from impurities.

Title: Method of improving the properties of kaolin and clays containing kaolinite
IPC: B01J20/12
Filed: 1964-01-27
Abstract: The properties of kaolin and clays containing kaolinite are improved by the preparation of kaolinite intercalation compounds (e.g. with urea, ammonium acetate, formamide and hydrazine) which are subjected during formation or subsequently to mechanical treatment, e.g. by pressing through a nozzle, rolling, grinding or trituration.  The intercalation compounds are formed by stirring the organic compound with kaolin and allowing to stand at temperatures from less than 65 DEG  C. to 110 DEG  C.  The intercalation compounds may be further treated with other compounds (e.g. dimethylformamide) which are not capable of directly forming intercalation compounds.  The intercalated compounds may be removed again, e.g. by addition of water or solvents, evaporation, evacuation or heating.  Examples illustrate the increased distance between layers in the lattice, improved thixotropic properties, dry-breaking strength and adsorption capacity.
