Patent GB-857136-A (GB)
Title: Improvements in or relating to catalysts for carbon monoxide conversion
IPC: B01J23/86
Filed: 1959-02-13
Abstract: A catalyst for use in the reaction of carbon monoxide with steam is prepared by heating a mixture comprising a major proportion of ferric oxide and minor proportions of a chromium salt or oxide and copper sulphate to a temperature below the decomposition temperature of the copper sulphate.  A minor proportion of an oxide or salt of potassium, aluminium or magnesium may also be present in the mixture. The catalyst may be reactivated by increasing the proportion of steam to carbon monoxide.  In an example 100 parts Fe2O3, 5 parts Cr2O3 and 3 parts K2O were mixed, an aqueous solution containing 4 parts CuSO4 was added, and the mixture was heated to 350 DEG C. and moulded into tablets.  Comparative catalysts omitting the CuSO4 or replacing it with CuCO3 were also prepared.  These catalysts were used to react steam with pure CO and also with a raw gas comprising, in addition, CO2, O2, CH4, H2, N2 and H2S.

Title: Process for the production of bitumen or oil emulsions
IPC: C08L95/00
Filed: 1926-02-24
Abstract: 271,177. Potts. H. E., (Mineral Akt.-Ges. Brig.). Feb. 24, 1926. Emulsions, making. - Bituminous emulsions, for use as waterproof coatings and in road making, are prepared with the aid, as emulsifying agents, of sulphurized oils or sulphurized fatty acids. In one example, 3-5 kg. of train-oil previously treated with 15-20 per cent of sulphur chloride, is added to 100 kg. of bitumen at 210-230‹ F. and 1-15 kg. of caustic soda dissolved in 10 kg. of water stirred in. The mixture is then emulsified in Plauson mill with 45-50 kg. of water containing 0.5-2 kg. of sodium or potassium carbonate. According to another example, 100 kg. of bitumen are melted with 2 kg. of sulphurized oleic acid and 2 kg. of sulphurized resin oil or resin acid and to the mixture is added 1 kg. of each of caustic soda and caustic potash in 10 per cent aqueous solution. 20---50 kg. of water containing 0.5 per cent of soap, or of sodium lysalbinate or other fatty amino acid soap are then added with stirring and cooling to 120‹ F. According to a third example, a mixture of bitumen with 3-5 per cent of linseed oil and 5 per cent of sulphur are heated to 150-180‹ C. and then emulsified with 1-15 per cent of caustic soda in 20 per cent aqueous solution. The linseed oil and sulphur may be increased to 20- 50 per cent of the bitumen; the product then obtained shows a rubber-like elasticity and, on exposure to sun and air, becomes unmeltable. Finely-divided brown coal or lignite or the products obtained by treating these substances with alkalies mav be added to the emulsions. The apparatus employed may be a colloid mill or a steam-jacketed stirring kettle. The bituminous materials emulsified may be natural or petroleum bitumens, coal-tar pitch or like products or other viscous oils employed in the treatment of road surfaces.

Title: Improvements in and connected with asphaltic pavements
IPC: E01C7/18
Filed: 1943-04-01
Abstract: Coated aggregates for the preparation of asphaltic paving mixtures are rendered capable of being stored indefinitely till required for mixing by incorporating one or more of the following modifications into the process according to the parent Specification.  (a) The coarse aggregate (which consists of material divided from the fine aggregate at 1/4 ") after being coated with a hot, thin film of number 2 or 4 tar or 45-200 penetration bitumen, is stabilized with 1-3 per cent of a filler such as hydrated lime, cement or slate dust in the form of a finely-divided powder of which preferably 85 per cent passes a 200-mesh sieve.  (b) The coarse aggregate (divided at 3/16 ") is coated with preferably a 62 per cent tar or bitumen emulsion prepared according to B.S.S. 618 or 434.  (c) The fine aggregate is treated with about 1 per cent of a flux such as anthracene oil or creosote, which can be applied to the stone either before the hot bitumen or tar coating, or in admixture with it.  The separate aggregates can then be mixed when they are to be used as no further heating is necessary.  In the case of the stabilized coarse aggregate, about 1 per cent of a flux consisting of bitumen or tar in benzole will normally be required to be added just before the fine aggregate is mixed in.  Also about 1/2 per cent of a water-retentive chemical, such as calcium sulphate, should be added in wet weather. Although not so important in the case of the emulsion-coated coarse aggregate, the use of a flux at the mixing stage will greatly assist spreading.

Abstract: 1,034,646. Coating and impregnating webs. J. DEMETER. Feb. 11, 1963 [Feb. 19, 1962], No. 5497/63. Heading D1L. Apparatus for coating and/or impregnating a web e.g. a textile web 2 with plastics material e.g. a resol resin comprises a first, heated-rotating roller 1 or 1<SP>1</SP> on to which the plastics material is fed to be melted, a second adjacent, heated roller 5 or 5<SP>1</SP> rotating in the same direction as the associated first roller but at such a speed that the layer of plastics material thereon is less than that on the first roller and means to direct the web 2 about the second roller so that the plastics layer is transferred thereto. As shown the web is pressed against each roller 5, 5<SP>1</SP> by belts 6, 6<SP>1</SP> and heated by devices 7. However the roller 5 rotates with peripheral velocity opposite to that of the web while roller 5 rotates with peripheral velocity of the same direction as the web; thus roller 5 applies a coating while roller 5<SP>1</SP> causes impregnation of the web. The speeds and temperatures of all the rollers is adjustable. In Fig. 2, (not shown), only one pair of first and second rollers is provided and a doctor 4 is thus provided on the first roller to determine the thickness of the coating. Various arrangements are shown in which either or both sides are impregnated and/or coated. In Fig. 9, (not shown), a filter device filters the melted plastics material as it passes about the first roller.

Title: Improvements in electric selective control systems
IPC: B60L15/12
Filed: 1923-02-27
Abstract: 195,363. British Thomson-Houston Co., Ltd., (Assignees of Connely, C. B.). March 25, 1922, [Convention date]. Selective distant control systems. - In a control system, such as is employed for operating an electric railway vehicle from a track station, selective electromagnetic switches on the vehicle respond to different strengths of current admitted to a supply conductor. When a number of track stations control successive block sections, track relays are employed to render short intermediate conductors dead in case an operator attempts to send a vehicle on an occupied section. Push-button switches manipulated by adjacent track section operators enable vehicles to pass each other or to enter the same section in exceptional circumstances. Fig. 1, in the upper part, shows a control station having four switches and four resistances, and, in the lower part, a group of four motors and corresponding relays. The operator by closing, for example, a switch 43 sends a current of corresponding strength to a set of lock-out switches 14, 15, 16, adjusted to respond to different currents. The particular lock-out switch thus selected closes one of the motor relays 17 - - 21, and connects the corresponding motor to the supply, simul. taneously opening the selection circuit so as to exclude the introduction of another motor while the first is in action. Fig. 2 shows, in the upper part, two track stations controlling separate conductor-sections. 66, 92, and, in the lower part, the motors and relays of two vehicles. In this arrangement the operator at each track station, for example the, left-hand station, by moving a control switch 64 to one side or the other, selects forward or reverse travel for a vehicle on the block section 66; the selective action taking effect through lock-out switches 67, 68, 63, and the usual gradual starting of the motors being effected by consecutively-acting resistance contactors 77 - - -80. A track relay 83 normally energized by a battery 89 is short-circuited whenever a vehicle enters the section 92, so as to cut out an intermediate insulated conductor 90 and thereby prevent the entrance of the vehicle from the section 66. Push-button switches may be made accessible to the operators for the purpose of keeping alive the conductor 90 when vehicles are passing or entering the same section.

Title: Improvements in or relating to magazine gramophones
IPC: G11B3/085
Filed: 1928-05-25
Abstract: 317,703. Waterworth, E. N. May 25, 1928. Divided on 317,895. Magazine gramophones; returning tone-arm to starting- position.-In a magaz i n e gramophone, mechanism is provided whereby, after a record has been changed, the tone-arm is moved by a cam or like member so that the needle rests on the edge of the record, and a further member is then moved by frictional engagement with the tonearm or with a member carried thereby, so that the needle is gently urged into the sound-groove. The invention is shown as applied to a machine similar to that described in Specification 300,814. At the end of the playing of a record, a wheel 39 makes one revolution and causes a lever 41 to oscillate. This lever carries a bar 43, which effects the raising of the tone-arm 24 through a member 45, and also carries a pivoted plate 48 which, by engagement with a pin 49 on a plate 50 rigid with the tone-arm, moves the tone-arm outwardly. After a fresh record has been placed on the turntable, for example by mechanism as described in Specification 317,895, the tone-arm is moved inwards until the needle is over the edge of the record, and is then lowered. This inward movement is caused by the action of the edge of the plate 48 on a pin 75 on the plate 50, the action ceasing when the edge of the member 48 brushes past the pin. The extent of inward movement is suited to the size of the record on the turntable, and is determined by the automatic setting of the plate 48 under the control of a stop 76. This stop is linked to a platform 8 which supports the pile of records (not shown), and as the platform is set so that it supports either a ten-inch or a twelve-inch record, so will he stop 76 be set in either of the two positions which govern the appropriate action of the cam 48. When the wheel 39 has nearly completed a revolution, a stud 102 thereon rocks a spring-controlled lever 80. This lever has pivoted upon it an arm 82, an edge 104 of which is formed with two notches 108, and lightly bears, under spring action, against a stud 105 on the plate 50. As the arm 82 moves forward through the action of the pin 102, one of the notches 108 engages the stud 105, and the frictional drag thus exerted moves the tone-arm further inwards until the needle enters the soundgroove on the record; thereupon the arm 82 is rocked by contact with a stop 106, so that it is then disengaged from the pin 105, and at this stage the wheel 39 stops.

Title: Improvements in and relating to distillation retorts, gas generators and the like
IPC: C10B1/04
Filed: 1928-02-25
Abstract: 312,394. Winby, L. P. Feb. 25,1928. Producers; retorts and methods of working.- In gas generators or retorts using pulverized fuel, in which the distillation zone is driven from one end to the other of the shaft and a non-porous layer is formed, the passage of the gases effecting the distillation through the charge is facilitated by bye-pass passages, whereby these gases are passed round any non-porous layer to effect distillation of further undistilled material. In down-draught distillation a semi-plastic non- porous layer is formed at the upper part of the fuel bed and travels down the latter, the heating gases passing into an annular space t through ports f controlled in turn by a series of dampers g, so that the non-porous layer is bye-passed during its descent. The gas and residue are withdrawn through a bottom outlet d. In a modification, a central hollow shaft with valvecontrolled ports is also provided, the fuel bed in this case being of annular form. In other modifica.tions, the bye-pass passages may be independent and only extend for a portion of the height of the shaft.
