Abstract: 1,186,513. Electro-physical measurement - thickness. GEVAERT-AGFA N.V. May 8, 1967 [May 13, 1966], No.21433/66. Heading G1N. Transverse thickness variations in a moving conductive web or coating e.g. light-sensitive layers on a triacetate base, are determined by measuring the resitance of parallel longitudinal strips. The method of measuring the resistance is by passing the web over A. C energized rollers providing a capacitative coupling to the conductive layer, and measuring the voltage drop across a resistor in series with one of the rollers. As shown one of the rollers 21 is formed with a series of conductive sections 23 each connected to earth through equal resistors, mounted inside the roller together with a stepping switch to connect each section sequentially to a recorder 30, (as illustrated in Fig. 2b not shown). The absolute thickness, instead of relative thickness, may be determined by making the supply voltage dependent on the specific resistance of the coating material Fig.3 (not shown).

Title: Process of and apparatus for the production of pure aluminium from aluminium-containing raw materials
Filed: 1951-09-12
Abstract: In a process for producing pure aluminium from aluminiferous metallic material by converting the aluminium into gaseous compounds, especially aluminium sub-halides, and then depositing aluminium in metallic form from the gaseous phase, the surface of the aluminiferous metal melt and the deposition surfaces are both plane and are situated directly opposite each other at a short distance apart.  Preferably the two surfaces are separated by a gas-permeable layer of chemically inert, heat resistant substance having good heat insulating properties, e.g. alumina or magnesia. In one example described, a porous layer of loose pulverulent alumina is applied directly to the surface of a crude metal melt in a reaction vesssel containing aluminium chloride.  The upper surface of the porous layer acts as a deposition surface and, due to the temperature drop through the layer, pure aluminium separates there.  In another example, the pulverulent alumina layer has progressively decreasing grain size, the crude metal melt overlying the upper surface of fine particles and the aluminium being deposited at the lower surface of coarse particles.  In a further example, the layer, in the form of a coherent but porous plate or of a pulverulent substance held between two foraminous plates, is arranged vertically and divides the reaction vessel into a part containing the melt and a part in which the deposited pure aluminium collects.  The process is carried out in the absence of oxygen and nitrogen, and may be under pressure or in vacuo, and the porous layer may have auxiliary cooling units to ensure sufficient temperature drop for the aluminium to separate. The wall of the reaction vessel is kept at a temperature above the boiling and subliming temperatures of the reaction medium and aluminium compounds by additional external insulation or by external heating.

Title: Continuous process for drying, preheating, and devolatilization of carbonaceous materials
IPC: C10B57/08
Filed: 1953-08-04
Abstract: 756,744. Distilling solid carbonaceous materials. SILVER ENGINEERING WORKS, Inc. Aug. 4,1953[auk. 12, 1952], No. 21513/53. Class 55( 1 ). In a process of distilling low rank carbonaceous fuels the dried finely divided fuel is passed in a hot carrier gas containing free oxygen upwardly through a zone where gases, tars and light oils are distilled from the fuel, the residence time of the fuel in the distillation zone being limited so that it is subjected to partial but incomplete combustion. In Fig. 2 crushed low rank fuel, e.g. lignite containing about 30 per cent moisture, is fed by a conveyer 15 from a hopper 12 to a drier 16 where it is entrained in hot gases from a combustion chamber 17. The mixture passes into a separator 40 and the separated dried fuel collects in a hopper 25 and a bin 41 before passing by line 46 and feeders 47 and 50 into line 49 for transfer by preheated air from line 52 to the carbonization zone 53, Fig. 3. The gases from separator 40 pass off by line 42 and are in part recirculated through the drier by lines 31 and 34 and ports 36 and 37 or treated in further separators 44 for removal of fines. The separated fines collect in a hopper 24 and are passed with further fuel fed from hopper 25 by line 51 to a burner 22 and combustion chamber 17 for producing hot gases for the drier 16. Air for the burner 22 is fed by fan 20 into an annular jacket 21 surrounding the combustion chamber 17. Fuel for starting the process may be supplied to the burner 22 by line 30. The carbonization zone 53 is heated externally by combustion gases from a burner 63 to which coal gas is supplied by header 64 and a mixture of air (from line 56) and recirculated flue gases (from line 57) via line 59, preheater 60, chamber 61 and line 62. Flue gases from the burner 63 not recirculated pass out through preheater 60, a preheater 67 and then either to stack by line 74 or by line 88 to a scrubber 89 to supply cleaned flue gases for transporting char from a feeder 85. Preheater 67 preheats air admitted through fan 69 and line 68 for supply to line 52. Dried fuel from line 49 and preheated air from line 52 pass with coal gas supplied from header 64 by line 7 la into the carbonization zone where the fuel is distilled at about 900‹F., the residence time in the zone being about 10-15 minutes. Char, distillation gases, tar and light oils pass by line 77 to insulated separators 82, the char falling by line 80 to feeder 85 and thence by line 87 to a boiler and the gases, tars and light oils leave by line 84 for further treatment. In a modified form of the apparatus the carbonization zone comprises a double-walled vessel the bottom of the inner shell being provided with a grid through which the line feeding dried fuel from the drier extends. In operation the outer shell of the carbonization zone is externally heated by combustion gases and combustion gases are circulated downwardly between the two shells of the zone and pass upwardly through the grid into the carbonization zone.

Abstract: 504,245. Grinding. DECKEL, F. July 21, 1938, No. 21661. Convention date, Aug. 5, 1937. [Class 60] A device for rotating a work-piece in a grinding-machine or other machine tool wherein the rotation is produced by longitudinal movement of the work - carriage, comprises a wheel, rolled upon a stationary member, and coupled to a work-holder mounted on the carriage. As shown in Fig. 1, the workcarriage 3 slides on a guide 1 on a frame 2 and in a part 4 of the carriage are mounted engaging bevel wheels 5, 6, the wheel 5 being secured to a hollow shaft to which the workpiece 7, shown as a milling-cutter, can be secured by a knob 8, a scale disc 9 serving for indexing the work. The wheel 6 is secured to a shaft 10, which has thereon a disc wheel 17 engaging a spring-pressed bar 12 carried by a stirrup 13 adjustably secured to the frame 2 by a slot and a screw 14 ; longitudinal movement of the carriage causes rotation of the work to an extent determined by the diameter of the wheel 17, which is interchangeable. In order to reverse the rotation of the work, the stirrup is moved and the bar is reversed so as to engage the wheel 17 on the other side of its axis. In a modification, a steel band is wrapped round the wheel in place of the use of the bar. A further modification employs a disc wheel on the work-holding shaft engaged by a steel band led round guide rollers - the carriage and secured at its ends to the frame. In both forms employing a band, this may be fixed at one end and adjustable, to tension the band, at its other end. In order to treat conical work-pieces, the work-holding part 4 is angularly adjustable on the carriage 3.

Title: Improvements relating to acid-removal or anion-exchange processes for the treatment of water or other liquids
IPC: B01J41/00
Filed: 1945-08-24
Abstract: A process for removal of extremely weak acids, to which methyl orange is insensitive, from water or other liquid containing strong and weak acids, consists in passing the liquid through anion-exchange material which has been treated or regenerated with caustic alkali, the flow being stopped before the effluent contains any substantial quantity of weak acid, and the material being regenerated at this stage.  The process may be applied to the removal of carbonic acid or silicic acid from water which is passed first through a bed of hydrogen - ion-exchange material before passing through the bed of anion-exchange material. Instead of using one anion-exchange bed, two such exchangers in succession may be used, the first serving to remove strong acids, and the second serving primarily or even completely to remove weak acids.  When the water contains carbon dioxide the water may be treated with air to remove part of the carbon dioxide, after leaving the hydrogen - ion - exchange bed and before reaching the last anion-exchange bed.

Title: New organic vanadium compounds and their use in the polymerisation of olefinically unsaturated hydrocarbons
IPC: C08F4/12
Filed: 1964-05-27
Abstract: The polymerization and/or copolymerization of at least one olefinically unsaturated hydrocarbon is effected by using as catalyst components, a reducing agent and a vanadium sulphonate of the formula <FORM:1004680/C3/1> wherein each R is a saturated or unsaturated aliphatic (including araliphatic) or cycloaliphatic hydrocarbon radical or an aromatic hydrocarbon radical (see Division C2). Suitable reducing agents include organo-metallic compounds, e.g. of metals in the first to the fourth group of the Periodic Table such as aluminium alkyl compounds, including mixed aluminium alkyl halides. The polymerization may be carried out in the presence of an organic diluent, e.g. a hydrocarbon in which both the vanadium salts and the organo-metallic compounds are soluble. The catalyst may be prepared by mixing the catalyst components in the presence or absence of solid carriers and in the presence of an organic diluent which is suitably a saturated aliphatic, cycloaliphatic and/or aromatic hydrocarbon. Suitable polymerization temperatures are between -20 DEG  C. and 150 DEG  C. and suitable pressures are between 1 and 50 atmospheres. When aluminium alkyl halide compounds are used as reducing agents, the atomic ratio of aluminium to vanadium is usually between 1 : 1 and 20 : 1. The polymerization may be carried out batchwise or continuously.  An example is given in which a mixture of ethylene and propylene is copolymerized in isooctane and benzene as solvent, in the presence of AlC2H5Cl2Al(C2H5)2Cl and vanadium (C8-C13) alkyl benzene sulphonate.ALSO:The invention comprises organic vanadium compounds having the formula <FORM:1004680/C2/1> wherein each R is a saturated or unsaturated aliphatic or cycloaliphatic hydrocarbon radical or aromatic hydrocarbon radical.  The aliphatic radical R may be substituted by an aryl radical. Preferably R is a C8-C20 alkylbenzene radical. They may be obtained by reacting vanadium hydroxide with the free sulphonic acid, preferably by adding the sulphonic acid to a dispersion of the vanadium hydroxide in a hydrocarbon and distilling off the water formed azeotropically. An example is given for the preparation of an alkyl benzene sulphonic acid vanadium salt.  The compounds may be used in conjunction with other catalyst components in the polymerisation of olefinically unsaturated hydrocarbons (see Division C3).
