Title: Methods of and apparatus for stirring immiscible conductive fluids
Inventor: CAMPBELL JOHN
IPC: H05B6/34
Filed: 1969-02-17
Abstract: 1,272,844. Electromagnetic mixing. BRITISH IRON & STEEL RESEARCH ASSOCIATION. 17 Feb., 1970 [17 Feb., 1969], No. 8446/69. Heading B1C. [Also in Divisions B3 and H5] In a method and apparatus for stirring mutually immiscible electrically conductive fluids, an electric current is passed through the interface between the fluids and a magnetic field is arranged to generate oppositely directed forces in the region of the interface. As described, in an electroslag refining process a consumable electrode furnace has a non- magnetic container 1 with superimposed layers of molten metal 3 and liquid slag 4 into the latter of which dips the electrode 5 from which current passes to the baseplate 2. A coil 11 embraces the container at the level of the interface between the metal and slag and its field 2 interacts with the current in the fluids to generate forces tending to rotate the slag and metal in opposite directions 13, 14. The coil and electrode are vertically adjustable. In modifications the magnetic field intensity may be varied by an adjustable transformer (15, 16, Fig. 3, not shown) or resistor (17, Fig. 4, not shown); there may be two coils with their fields opposed to give an increased stirring effect on a plane which may be located in the slag layer immediately above the interface (Fig. 5, not shown); three coils may be used to produce increased stirring action in both layers (Fig. 6, not shown); a parallelepipedal container may have electro-magnets or coils at opposite faces to give a stirring action in vertical planes (Figs. 7 and 8, not shown). Alternating or direct current may be used and the electro-magnets of Fig. 7 may be replaced by permanent magnets.

Title: Improvements in or relating to arc welding
IPC: B23K9/02
Filed: 1966-02-25
Abstract: 1,087,506. Welding by fusion. CHICAGO BRIDGE & IRON CO. Feb. 25, 1966 [April 8, 1965], No. 8475/66. Heading B3R. [Also in Division G1] In an arc welding apparatus having a welding head which moves upon a track and carries the welding torch, a photo-cell is mounted upon the head and controls the movement of the head in accordance with the intensity of light received from the arc and pool of molten metal. As shown in Fig. 3, a water-cooled shoe 27 retains the molten weld metal 13 in a vertical joint and passes light from the weld area through a hole 40 on to a photo-sensitive resistor 30. The intensity of light received depends upon the distance of the hole 40 from the surface of the molten weld metal and the object of the control is to match the movement of the head to the rate of deposit of weld metal. In one arrangement the head is moved in stages at constant speed, the movement starting when the level of molten metal rises to cause a predetermined light intensity to fall on the resistor 30. In another arrangement the head movement is continuous and the speed varied in accordance with the photo-cell output. The light falling on the photo-cell may be adjusted by the valve 36 shown or one of a number of various diameter rings placed in the light passage (Figs. 5 and 6, not shown) or an iris diaphragm. Carbon dioxide or argon is pumped into the light passage to the photo-cell to maintain the hole 40 clear and provide an inert atmosphere at the weld area. The apparatus may exclude the shoe and may be horizontal.

Title: Improvements in ignition timing and like couplings
IPC: F02P5/06
Filed: 1946-03-19
Abstract: 610,567. Automatically adjustable couplings. BENDIX AVIATION CORPORATION. March 19, 1946, No. 8518. Convention date, March 27, 1945. [Class 80 (ii)] [Also in Group XXVII] In an ignition timing coupling (see Group XXVII) a driving member 12 and a driven member 13, Fig. 3, are coupled together, through intermediate members 14, 15 in a manner which permits of relative angular displacement by centrifugal means consisting of six arcuate plates arranged in pairs 16, 17, 18, Fig. 1, one plate of each pair being on either side of the members to which they are connected. The pairs of arcuate plates 16, 17, 18 are pivoted at one end to their respective members 12, 14, 13, whilst between the other ends are positioned rollers that co-operate with slots 37, 49, 61 respectively. Each arcuate plate, which has a weight 56 riveted opposite its pivoted end, is spring connected to an inner point of the arm of the member to which it is pivoted. Anticlockwise rotation at or below the speed at which the coupling occupies the position shown in Fig. 1 provides for spark advance, whilst at a predetermined higher speed the roller end of the pair of arcuate plates 18 moves to the end of slot 61 since spring 64 is lighter than two other springs 41, 52, which control the pairs of arcuate plates 16, 17 respectively, causing the intermediate members 14, 15 and driving member 12 to experience an anti-clockwise movement, thereby retarding the ignition. At a higher speed, the pair of arcuate plates 16 pivot outwardly since the spring 41 is lighter than spring 52 and as a result intermediate members 14, 15 and driven member 13 move anti-clockwise until an adjustable stop 69 on the latter contacts the driven member 12, in which position the ignition is fully advanced. At a still higher speed, the pair of arcuate plates 17 become operative, thereby causing driving member 12 and intermediate member 14 to move anti-clockwise and so retard the ignition.

Abstract: 1,143,922. Modified montmorillonite. GEORGIA KAOLIN CO. 25 Feb., 1966 [5 March, 1965; 22 Nov., 1965], No. 8539/66. Heading C1A. A modified montmorillonite contains exchangeable cations consisting essentially of the following per 100 gins thereof; (I) at least 5 milliequivalents of Ca and/or Mg, (II) at least 5 milliequivalents of NH 4 <SP>+</SP>, and (III) 0 to 20 milliequivalents of Na and/or Li. (I) may be in amounts up to 60 milliequivalents, and (II) to up 65. The modified montmorillonite may be prepared by heating a sodium or alkaline earth metal bentonite to 220-230‹ F, e.g. in a drum drier, to a water content of not more than 15 %wt. This is slaked by mixing 10-30 thereof with 90-70 parts water and is violently agitated to produce a mixture of hydrated montmorillonite (#0À5 Á), quartz (2-80 Á), and cristobalite (0À5-2 Á). The quartz and crystobalite may be removed by screening at this stage or later. The slurry is then treated with a source of NH 4 <SP>+</SP> with or without Na<SP>+</SP> and/or Li<SP>+</SP> to effect substitution of the alkaline earth metal cations and obtain the modified montmorillonite with a particle size less than 0À1 Á. The crystobalite and quartz may be separated, e.g. by centrifuging, and the modified montmorillonite dried. The NH 4 <SP>+</SP> compound may be (NH 4 ) 2 CO 3 , (NH 4 ) 2  C 2 O 4 , NH 4 F, or ammonium phosphate. The Na<SP>+</SP> compound may be sodium acetate, NaF or Na 2 C 2 O 4 , the Li<SP>+</SP> compound may be Li 2 CO 3 , lithium citrate or Li 2 C 2 O 4 . When (NH 4 ) 2 CO 3  is used sodium pyrophosphate or NH 4 OH may be added thereto. The modified montmorillonite may be dispersed in water to give a stable dispersion between pH 1 and 12, the viscosities of which are exemplified. The modified montmorillonite may be substantially free from water-soluble Ca and/or Mg compounds. The modified montmorillonite can be mixed with an amount of a source of Na and/or Li ions at least equivalent to the total amount of exchangeable NH 4 <SP>+</SP> and exchangeable Ca and/or Mg ions in the modified montmorillonite.

Filed: 1966-02-26
Abstract: 1,161,051. Laminates. DUNLOP CO. Ltd. 10 Feb., 1967 [26 Feb., 1966], No. 8560/66. Addition to 1,091,943. Heading B5N. [Also in Division Dl] A method for the manufacture of an unvulcanized rubberized textile filamentary fabric comprises longitudinally compressing textile filaments and applying an unvulcanized rubber composition into adhering contact with the filaments either before or after compression of the filaments, the filaments being supported by a longitudinally resiliently extensible sheet material having a surface made of a polymeric composition comprising polychloroprene. The extensible surface may comprise a blend of polychloroprene with polybutadiene, with copolymers of butadiene with styrene or acrylonitrile or with ethylene-propylene copolymers. The unvulcanized rubber is preferably natural rubber admixed with conventional valcanization ingredients and may be applied in sheet form or as a latex or solution. Specified filaments are those of nylon, cotton, rayon, polyester, glass and metal. A substantially extensible backing, e.g. rubberized uncompressed textile threads of lower tensile strength than the filaments or a polyethylene sheet may be applied to the rubberized fabric preferably prior to removal of the fabric from the sheet material. In a preferred embodiment a layer of the unvulcanized rubber is applied to each surface of the filaments prior to compression. In the drawing, a conveyer belt 2 having a surface of polychloroprene rubber extends around rollers 4 and 6, nip rollers 4 and 5 being driven at a higher peripheral speed than rollers 6 and 7 thus stretching the belt. A layer 15 of textile filaments embedded in an unvulcanized rubber composition is applied to the stretched polychloroprene surface of the belt by nip rollers 4 and 5, the belt contracting and hence compressing the filaments on leaving the nip, and a backing layer 10 of an unvulcanized rubber containing textile threads applied to layer 10 and the composite passed over heated drum 12.

Abstract: 721,378. Typewriters &c. for embossing printing-plates. ADREMA MASCHINENBAU GES. April 4, 1952 [April 5, 1951], No. 8654/52. Class 100 (4). In an embossing machine for addressprinting and like printing plates with oppositely movable doublearmed type levers for displacing the patrix and matrix interconnected at one end by a toggle-pair the toggle joint of which is connected by a link to an operating lever pivoted on the machine casing, auxiliary displacing means are so arranged between the operating lever and one end of the matrix-displacing lever that the end of the matrix-displacing lever is positively conveyed by the operating lever into a pre-determined position, in which it is supported on a fixed point of the casing, prior to the embossing operation and prior to the completion of the patrix stroke. The levers 4, 5, Fig. 2, are pivoted at 6, 7 and caused to move together at their operating ends to displace the type stamps mounted in the type wheels 2, 3 to emboss the plate, the stamps in the wheel 2 being matrices and those in the wheel 3 patrices. The levers 4, 5 are actuated by an operating lever 12, the arrangement being such that movement of the upper end of the operating lever to the left first raises the selected matrix by means of a toggle 18, 19, pivoted to a fixed point 20 and connected to the lever 12 by an intermediate lever 21. When the matrix is in its raised position, the pivot pin 13 of the toggle lever 18 and the lever 4 becomes stationary, whereupon further movement of the lever 12 completes the lowering of the selected patrix through a toggle 15, 16 connected to the lever 12 through an intermediate lever 17. Reverse movement of the lever 12 moves the operating ends of the levers 4, 5 apart. In another form, Fig. 6, the lever 21 is pivoted to a disc 22 pivoted at 20 and having a guide slideway 23 to receive the pin 13. In a further form, Fig. 7, a lug 26 on the lever 12 constitutes the displacing mechanism for the lever 4, having a guide slideway 27 for a pin 28 on the lever 4.

Title: Improvements relating to mechanical braking systems
IPC: B66D5/00
Filed: 1941-07-17
Abstract: 549,062. Fluid-pressure brakes. SMITH, G. D., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. July 17, 1941. No. 9062. [Class 103 (i)] A brake-applying weight is coupled at least in part through a spring to a brake applying lever and a fluid-pressure servo device normally holds the weight raised against an abutment and the spring stressed. Upon lowering the servo piston pressure is applied to the lever and thus to the brake first by the spring and the weight then leaves the abutment and gradually augments the pressure applied to the lever. Specification 508,895 is referred to. In Fig. 1, the cross-head 20 of a fluid-pressure servo-device 21 is connected by link 18 to a floating-lever 14 which is connected by links 12, 16 to the weight 9 and to the brake lever 8 pivoted at 5 and connected by links 6, 7 to brake shoes. A spring 10 is connected to the weight and to the lever 8. Normally the weight is held against an abutment 22 and the spring is tensioned. When by reducing the pressure in the cylinder 21 the link 18 is caused gradually to descend, the lever 14 first turns about the pivot 13 and the lever 8 turns under the action of the spring 10 to apply the brake the weight 9 then leaves the abutment and gradually increases the pressure applied to the lever. The initial tension of the spring may be somewhat greater than the maximum braking force and during a brake application may fall to a minimum value which is somewhat smaller than the maximum and then increase to the maximum, the actual braking force increasing continuously from zero to this maximum. In the event of failure of the spring the weight becomes effective on the lever 8 through a link 23. In a modification, the weight is mounted on the end of a pivoted arm which is connected by a vertical link to a cross-head to which the longer ends of the link 12 and spring 10 are connected. In a further modification, the floating-lever 14 and links 12, 16 are dispensed with, the link 18 being directly connected to the lever 8 at the point 11.
