Inventor: MICHEL ERNST
IPC: E06B1/38
Filed: 1953-09-15
Abstract: 739,399. Cover strip for window and door frames. FUCHS, H. J. Sept. 15,1953, No. 25436/53. Class 20 (3). A detachable metal cover ledge 3 for application to existing frame constructions of windows, show eases, doors, &c., is screwed, together with a snap ledge 5, or 5a, to the frame 7, e.g. of a window, the upper edge of the ledge 3 being received in a groove in a front ledge 2 screwed to a sill 9 and carrying a packing strip 10 to engage a panel 1, and a profile ledge 4, covering fixing screws 6, being sprung on to the snap ledge 5 or 5a. In a modification the cover ledge 3 is engaged on a snap ledge 5 or 5a, which is screwed to the outer vertical face of the sill 9, a packing strip being engaged between the upper edge of the cover ledge and the panel 1. In a further modification the cover ledge is screwed, together with an angle section profile member, to the upper face of the sill 9, one limb of the profile member, bendable to cover the screws passing through the other limb, having a packing along its outer edge which, when the limb is bent, presses up against the panel 1. Two other substantially similar embodiments show angle section profile members having limbs which can be folded over the screws securing them respectively to the side and under faces of the sill 9, both embodiments in this case showing a packing member interposed between the upper limbs of the ledge 3 and the panel 1. In the construction, Fig. 9, the cover ledge 13 has recesses on its inner surfaces to engage snap springs 14, 15 formed as continuous ledges, or as spaced shorter bars, and secured to the sill as shown, or to a metal profile secured to the frame 7. In a further embodiment, Fig. 11, the cover ledge 3 is secured by screws which are inserted through a groove 16 subsequently filled with wood 17 which accommodates an interlocking profile ledge 19. In another construction, a cover strip, substantially the same as that shown in Fig. 1, has a recess along its lower edge to accommodate fixing screws which are covered with wood filling, a metal profile, containing packing, being glued to the wood filling. Further constructions are described in which metal profile ledges, serving as coverings for the fixing screws, have corrugated sides, or spring ledges, to engage either with correspondingly formed surfaces on the walls of the recesses in the cover ledge or with spring ledges secured to the bottom of the corresponding recesses by the fixing screws.

Title: Improvements in or relating to hydrocarbon conversion
IPC: B01J38/12
Filed: 1945-10-02
Abstract: In reactivating a hydrocarbon catalyst laden with combustible material, the catalyst is arranged in a series of zones in the direction of flow, the zones being so constituted that equal proportions by weight of combustible material relative to catalyst are deposited in the several zones during a conversion, a hot-oxygen-containing gas is introduced into the first zone, a relatively cold oxygen-containing gas and steam is introduced to succeeding zones at points between the adjacent zones, the gas and steam introduced admixing with the hot gases leaving the preceding zone and the resulting mixture passing thence through the succeeding zone, and the volume, temperature and oxygen content of the gases at each zone is regulated to maintain their temperature within predetermined limits to burn simultaneously the combustible material in the zones in the same period of time. Preferably, the zones of catalyst are formed with progressively increased volume in the direction of flow and are separated by gaseous mixing spaces.  The temperature in each zone is preferably maintained between 700 DEG  F. and 1400 DEG  F.  A specific example describes the regeneration of a bauxite catalyst to be employed in cracking a charge stock, the catalyst being arranged in a tower in spaced zones of progressively increasing volume from the top to the bottom of the tower from which the spent activating gases are removed.  In the cracking stage, the hydrocarbons are also introduced at the top and removed at the bottom.  The invention is also applicable to catalytic desulphurization, dehydrogenation, hydrogenation, reforming and polymerization.

Title: Production of 5,6-dimethylene-1,2,3,4,7,7-hexachloro-bicyclo-[2,2,1]-heptene-(2)
Inventor: FUST KLAUS JUERGEN
IPC: C07C17/25
Filed: 1960-07-22
Abstract: A process for the production of 5,6-dimethyl ene - 1, 2, 3, 4, 7, 7 - hexachlorobicyclo - [2,2,1]-heptene-(2) comprises reacting 5,6-bis-chloromethyl - hexachlorobicyclo - [2,2,1] - heptadien-of the formula <FORM:0898378/IV (b)/1> with zinc or magnesium as a dehalogenating metal in an organic solvent which contains chemically bound oxygen and which is inert or substantially inert under the conditions of the reaction.  The term "substantially inert" is employed to mean that there may be a reaction between the solvent and one of the reactants or the reaction product but the velocity of this reaction is so slow compared with the velocity of the dehalogenation reaction that this side reaction does not influence the dehalogenation reaction to an undesired degree.  Solvents specified include alkanols having 1 to 6 carbon atoms, fatty acids having 2 to 4 carbon atoms, anhydrides thereof and their esters with alcohols having 1 to 4 carbon atoms, ketones containing 3 to 9 carbon atoms, aliphatic ethers containing 4 to 8 carbon atoms, cyclic ethers containing 4 to 6 carbon atoms, formamide and N-mono-and N,N-dimethylformamide, lactams having 6 or 7 ring members and which may be M-substituted by alkyl radicals with 1 to 4 carbon atoms.  In addition a hydrocarbon solvent such as benzene, toluene, cyclohexane, petroleum ether, ligroin and gasoline may be employed in admixture with the oxygen-containing solvent.  The oxygen-containing solvents may contain water up to 10% by weight of the total mixture. Hydroquinone and p-tertiary butyl pyrocatechol may be employed in the reaction mixture as polymerization inhibitions.  Examples are furnished.  5, 6 - Bis (chloromethyl) - 1, 2, 3, 4, 7, 7 - hexa - chlorobicyclo - [2, 2, 1] - heptadiene - (2, 5) is produced by heating 1,4-dichlorobutine-(2) and hexachlorocyclopentadiene together.  Specification 878,650 is referred to.

Title: Improvements in or relating to rotary pumps for use in fluid power transmissions
IPC: F04C14/26
Filed: 1955-09-08
Abstract: 772,349. Rotary pumps. VICKERS, Inc. Sept. 8, 1955 [Sept. 9, 1954], No. 25719/55. Class 110 (2). A sliding vane type pump having two abutments is adapted for use in a fluid power transmission where excess fluid supplied by the pump is diverted back to a reservoir or the pump inlet through a compensating valve characterized in that the compensating valve is operated by the pressure drop across a restricted discharge passage and the pump discharge ports and passages are so disposed as to minimize the length of the flow path for both the diverted and utilized fluid. The bore 16 of the stator 14, which accommodates the rotor 18 and vanes 20, is closed on one side by a housing member 10 and on the other side by a housing member 12 having an axially movable pressure-loaded plate 26 which is urged into fluid sealing engagement against the adjacent faces of the rotor 18, vane 20, and stator 14. The member 12 is enclosed by a fluid reservoir 11. Fluid is returned to the pump through an inlet connection 46 and into the reservoir 11. Fluid from the reservoir passes through passages 76, 74, 72, 70 to a pair of inlet ports 54 (Figs. 1, 5) formed in the member 10 which have corresponding opposite inlet ports 68 in the member 12. The fluid is discharged from the working spaces through outlet ports 56, 58 (Figs. 1, 5) in the member 10, arms 60, 62 (Fig. 5) of which communicate through passages 86, 80 (Fig. 3) with a pressure chamber 28 behind the pressure plate 26, and also through corresponding opposite outlet ports 64 (Fig. 1) in the plate 26. The arm 60 of the outlet port 56 also communicates through a small passage 78 (Figs. 1, 5) and a passage 51 with the pump discharge connection 46. Pressure in the passage 51 is communicated through a small passage 106, passages 108, 110 to a chamber 102 (Fig. 1) to act upon one end of a piston valve 94 together with a spring 104, the other end 96 of the piston being acted upon by the fluid in the pressure chamber 28, such that when the pressure in the chamber 28 exceeds that in the outlet passage 51 by a predetermined amount the piston 94 slides to the left allowing fluid in the chamber 28 to be discharged through passages 74, 76 to the pump inlet ports and the reservoir 11. When the pressure in the chamber 102 exceeds a predetermined maximum, a pilot relief valve 98 opens so venting the chamber 102 to the reservoir 11 and this causes the piston 94 to move to the left. Thus the fluid utilized in a transmission system for useful work passes through the small passage 78, the next being directed through the valve 94. Fluid pressure in the chamber 28 is transmitted to the inner ends of the vanes 20. Specification 689,220 is referred to.

Title: Electric arc welding
IPC: B23K9/173
Filed: 1959-07-28
Abstract: 876,729. Welding by fusion. AIR REDUCTION CO. Inc. July 28, 1959 [Aug. 6, 1958], No. 25910/59. Drawings to Specification. Class 83 (4). In carbon dioxide shielded arc welding using a consumable ferrous wire electrode, caesium is supplied to the arc to produce spray transfer of metal from the electrode to the workpiece. The caesium is added in the form of an hydroxide, carbonate, nitrate or chloride as a superficial coating on the electrode, the caesium constituting at least 0.01% of the total electrode weight. The welding is at straight polarity. Except in the case of rimmed steel or ingot iron electrodes it is necessary to use as the coating to produce spray transfer or mixture of a caesium compound with a compound of another alkali metal i.e. sodium, potassium, rubidium, lithium and francium, the added compound again being preferably an hydroxide, carbonate or a nitrate but sodium chloride may be used with caesium chloride. The ratio of caesium atoms to the atoms of the other alkali metal in the coating should be between 1 : 5 and 5: 1 optimum results occurring when the ratio is 1: 1. The wire is electrolytically cleaned in an acid bath before coating by immersion in a solution of the coating compounds. Examples of suitable coating mixtures and core wire compositions are specified. Specifications 684,011, 687,666, 712,259, 731,836 and 738,284 are referred to.

Abstract: 6 0 1,8 4 6. Temperature - responsive actuating-elements. LISLE, W. G. DE. Oct. 5, 1945, No. 25974. [Class 64(ii)] A control device for the temperature - operated shutters of a liquid cooler comprises bellows 10, 11, one arranged within the other, within a casing 1 and with an expansible filler between them, said bellows being adapted to operate a control rod 7 for the shutters which passes through the inner bellows, the bellows entirely surrounding the portion of the control rod extending within the casing. The ends of the bellows connect with end plates 8 and 81, guide plates 6 being arranged to prevent the outer bellows making contact with the rod and the casing, which may have perforations 2. A spring 13 in the adaptor 3 returns the control rod and bellows to their normal, positions. When the bellows space is restricted the corrugations may be made helical, the corrugations of the outer element interlocking with those of the inner element.
Patent GB-482137-A (GB)
Title: Improvements relating to filters for use in respirators and the like
IPC: A62B23/00
Filed: 1936-09-25
Abstract: Respiratory and other air filters comprise, as the component for removing suspended particles and droplets, an intimate mixture of fibres, including 5-30 per cent by weight of opened mineral fibres, for example chrysotile or crocidolite asbestos, such fibres being very fine or of small average diameter compared with the other fibrous constituent.  The other constituent is preferably combed wool but may comprise cotton, cellulose, or other vegetable fibres, natural or artificial silk, hair, or glass or slag wool.  A preferred mixture comprises 80 per cent of dry combed merino wool noils and 20 per cent of white chrysotile asbestos of average fibre length one inch and diameter one to two microns.  In an example asbestos is thoroughly opened up and a lap formed from the fibres is fed, together with a lap of combed merino wool noils, to a picker which feeds them in correct proportions to a carding engine.  The lap delivered from the carding engine is folded on itself to form a layer two to three inches thick from which discs or pads are cut or stamped out, the waste being returned to the carding engine.  The pads are placed in filter cells or containers of diameter slightly smaller than themselves and are held under slight pressure between gauzes or the like.  The filters may comprise gas-absorbing material such as charcoal as an additional component.  The Provisional Specification refers to the mixing of combed wool with opened asbestos fibres in bulk to produce a loosely matted mixed product, and states that a product comprising the mixed fibres may be wrapped around a perforated tubular or gauze core.

Title: Improvements in or relating to Lasers
IPC: H01S3/042
Filed: 1967-06-06
Abstract: 1,192,774. Lasers. UNION CARBIDE CORP. 6 June, 1967 [7 June, 1966 (2)], No. 26012/67. Heading H1C. In a laser the doped crystal rod is supported by two spider supports in a light transparent tube spanning a chamber in a housing so that a fluid may pass through the annular space between the transparent tube and crystal rod. As shown in Fig. 1, an elliptical chamber 12 formed in a housing is provided with an arc pumping light source 20 at one focus and a ytrrium aluminium garnet eloped by neodynium rod 22 at the other focus. The rod 22 is supported in a light transparent tube 23 by means of spiders 24, 24a, each of which comprises a sleeve-shaped outer structure 78, 80, a series of finger projections 82 being spaced around and attached to the inner walls of the sleeve members and extending radially inwards to form a loosely fitting spider-shaped holder for the rod, Fig. 2 (not shown). One end of the rod 22 is provided with a totally reflecting coating 90 and the other end face 96 with a partially reflecting coating. Light from the laser is extracted by means of a tubular member 98 fitted in borehole 54 in tubular end portion 50 extending into counterbore 42 and a transparent cylinder or light pipe 104 fitted in the end of the tube 98 and spaced from the end face 96 of the crystal. In operation a coolant fluid flows into inlet 116 in support member 44 clamped to the housing 13, through bore-hole 52 and into the tube 23. It then flows through tube 23 round the crystal to the opposite end of the tube, through the legs 82 and into annular channel 102 and out of outlet 120. Plug 88 shields the end face 90 of the laser rod from abrasion by the coolant. Alternatively, the laser rod may be provided with a hollow core forming a passage for the flow of coolant. The coolant fluid may be gas or liquid or refrigerated gases and may act as an absorber for undesirable radiations from the pump source. 0-Ring seals 66, 72, 108 and 112 prevent the escape of coolant fluid. Spring 58 serves to compensate for any expansion and contraction of the tube 23 and since the spider supports 24, 24a are loosely fitted around the ends of the rod they will allow for relief of any thermal stresses in the crystal by expansion and since spider 24 is slidable in tube 23, longitudinal movement is possible to remove stresses. In another arrangement the elliptical chamber may be a parabolic, hyperbolic chamber with one or more pumping sources. The elliptical chamber may be replaced by a cylindrical chamber with the laser positioned coaxial with the longitudinal axis and the pumping lamps being positioned parallel thereto around it or a helical lamp may be used.

Title: Static inverter
IPC: H02M7/537
Filed: 1964-06-24
Abstract: 1,045,369. Inverters. GENERAL ELECTRIC CO. June 24, 1964 [July 10, 1963], No. 26193/64. Heading H2F. In an inverter circuit of the type in which transistors 20 and 40 are driven alternately conductive by a gate source 36 to energize opposite halves of a centre-tapped primary winding 17, the secondary windings 94 and 100 of additional current transformers 90 and 96 form feedback windings to largely take over from the gate source and drive the associated transistor on by regenerative action. The gating source used to turn one transistor on also triggers S.C.R. 68 or 70 into conduction so turning the opposite transistor off by providing an easier by-pass path for the drive current, than through diode 106 or 108 and the base to emitter diode of the transistor. When leading or lagging currents flow and the associated transistor is non-conducting, the currents transfer to diodes 34 and 54. Capacitors 110 and 113 delay the turning on of the associated transistor until the stored charge carriers in the opposite transistor have recombined. Instead of using the gate source to hold the transistor off in a non-conducting part of its cycle the negative bias developed in the feedback winding by the decoy in flux linkages when the drive current falls may be used (Fig. 5, not shown). Diodes 106, 108 and capacitors 110 and 112 are then omitted and the S.C.R's are connected to ground. The transformers 90 and 96 may be wound on the same core (Fig. 1, not shown), but with a capacitive load taking leading current commutation failure is possible. The inverter circuit may be in the form of a bridge whereby two pairs of S.C.R's fire alternately to change the direction of current flow in the primary winding of the load transformer (Fig. 7, not shown).
