Abstract: 619,585. Tubular heat exchangers. GAS LIGHT & COKE CO., and NEWLING, W. B. S. Dec. 13, 1946, No. 36863. [Class 64(iii)] Relates to tubular heat exchangers of the type wherein a tube bundle 8 is mounted, in an outer shell 1, between fixed and floating heads 9 and 11, and the two fluids pass around and through the tubes respectively. According to the invention the tube bundle and floating head are of such a size as to permit their removal from the shell as a whole and a sheath 24 closely surrounds the tube bundle throughout its length, to reduce the gas passageway between the tube bundle and shell. The fixed head 9 is bolted to flanges 3 on the shell and carries a partitioned header through which one fluid enters and leaves the tube bundle. The floating head includes a domed header 21. The sheath 24 has ducts 27, 28 through which the other fluid flows, a partition 13 being provided to ensure circulation of this fluid around the tubes. The ducts 27 and 28 lie just clear of corresponding ducts 6 and 7 in the shell wall so that an open, stagnant air-space surrounds the sheath and floating head and assists thermal insulation. The tubes 8 are circular and are arranged to form a substantially circular bundle but the invention is also shown applied to circular tubes arranged in a hexagonal bundle and to flattened, rectangular tubes arranged in a square formation.

Abstract: 1356225 Determining position of blowing lance ALLEGHENY LUDLUM INDUSTRIES Inc 8 Aug 1972 [18 Aug 1971] 36889/72 Heading F4B [Also in Division G1] The depth of the tip 32 of a blowing lance in a molten metal melt 16 is determined by measuring the pressure difference between a conduit 28 within the lance and opening at the tip and the gas in the space above the bath. A gas under pressure, which may be an inert gas, air or oxygen, may be supplied to the conduit 28 to ensure that it does not become blocked, and the pressurized gas supply may be pulsed. Although the pressure difference fluctuates, an average reading may be obtained from a manometer, or the output from a differential pressure cell 54 may be fed to an integrator 58 to give a direct indication on a meter. If the melt is being blown in vacuo a constant volumetric flow of gas is supplied to the conduit to provide a stable reading. The conduit is preferably arranged to touch the lance wall, Fig. 2, to ensure that it erodes at the same rate, or it may be concentric with the lance or embedded in the refractory sheath of the lance.

Abstract: 1,241,062. Automatic control of speed. ENGLISH ELECTRIC CO. Ltd. July 30, 1969 [Aug. 2, 1968], No.36946/68. Heading G3R. A speed control system, e.g. for a gas turbine driving a generator, includes a shaft 4 for effecting speed adjustment, e.g. by throttle control, and which has a radially attached lever 2 connected to a hydraulic servo-device 14 for automatic control by a governor, and a change-over switch for neutralizing the servo-device and engaging a clutch 8 so that the shaft may be rotated by a manually controlled motor 10. Since no movement occurs until the motor is manually energized change-over from automatic to manual control causes no abrupt change in the speed; for smooth change-over from manual to automatic a meter is provided indicating the governor position which can then be matched manually. The motor 10 is electric and is controlled by a lever Fig. 2, (not shown) which, in the automatic mode controls a motor driven potentiometer which provides a reference voltage against which an actual speed signal from a magnetic pick-up is compared, the difference being applied on line 79 to a hydraulic control device 18. During starting the reference potentiometer is adjusted by an undisclosed "automatic synchronizer" (47) and the lever 2 is acted upon by a hydraulic piston 40. Damping is provided by a further piston 52 connected to the restrictor network shown, which is varied when a micro-switch 64 is actuated. 70, 72 are limited switches. Position feedback of the shaft from a differential transformer 76 is used for controlling the droop characteristic.

Title: Preparation of adiponitrile
IPC: C07C255/04
Filed: 1964-09-15
Abstract: Adiponitrile is made by heating a mixture comprising (a) acrylonitrile, (b) a metal carbonyl or a derivative thereof (as hereinafter defined), (c) hydrogen, or water, or water and a Lewis base, or hydrogen and water, or hydrogen and water and a Lewis base, and (d) a polymerization inhibitor.  The reactant (c), if it is not hydrogen, causes the release of hydrogen under the reaction conditions.  Suitable Lewis base are metal hydroxides, oxides such as magnesia and alumina, alkaline salts, amines and derivatives thereof, phosphines, arsines and stibines. The preferred metal carbonyls are those of the transition metals, particularly iron pentacarbonyl and dicobalt octacarbonyl.  The term metal carbonyl derivatives denotes the compounds in which the CO group is directly bonded to the metal and the metal is also covalently linked to one or more residues of other organic or inorganic compounds, e.g. triethylammonium undecacarbonyl triferrate, metal carbonyl hydrides and the compounds obtained by reacting a carbonyl with acrylonitrile or an olefin or acetylene. A hydrogenation inhibitor, e.g. quinoline, may be included in the reaction mixture.  Suitable reaction temperatures lie in the range 20-200 DEG  C.  Numerous examples are provided.

Abstract: 1351671 Automatic voltage regulation LICENTIA PATENT-VERWALTUNGSGmbH 12 Aug 1971 [18 Aug 1970] 37997/71 Heading G3X A shunt arrangement for limiting a supply voltage comprises a number of stages each including a power transistor and power resistors. Increase in supply voltage actuates each stage in succession to dissipate excess power. The transistor of one stage is allowed to reach a saturated state before a subsequent stage is actuated. In the embodiment described, a voltage from a solar generator in a space vehicle is fed on a line 11 to comparators 10 receiving reference inputs 12. A logic circuit 15 passes an output voltage to amplifiers 6, 7 which are connected directly to a first shunt stage 2a and through threshold circuits 8 and amplifiers 9 to further shunt stages 2b, 2c, 2d. By way of example, the stage 2b, Fig.2, includes a power transistor 20 connected in series with power resistors 21, 22 across the main supply line 35 connected to line 11 and ground 36. In operation, an output from the logic unit 15 causes power dissipation in the transistor 20 of stage 2a. Further increase in the supply voltage results in saturation of that transistor and also turns on transistor 28 in the threshold circuit 8 of stage 2b. The threshold level is fixed by resistor 32 which may be replaced by a Zener diode, Fig. 3 (not shown). The output from the threshold circuit is amplified by transistor 24 which controls the power transistor 20. Similarly, when this transistor saturates, the next stage 2c is triggered. By switching in additional stages only after saturation, sudden changes are avoided, since the power transistors dissipate only a small amount of heat in the saturated state.

Abstract: 885,924. Cleaning metals. KRAMER, W. Nov. 26, 1958. No. 38186/58. Class 82(2). [Also in Group XXII] A method of preparing cold-drawn wire for embedding in glass, prior to immersion of the wire in the molten glass mass, comprises the steps of subjecting the wire to a cleaning heat treatment at a temperature corresponding to the temperature to which the wire will subsequently be heated by contact with the molten glass, to remove grease and gas impurities, cooling the wire, cleaning off any combustion residue, and applying to the wire a surface layer which protects the wire against further gas absorption and/or oxidation and leaves no residue when the wire is brought near the molten glass. As shown, cold-drawn iron wire 1 passes successively through electricallyheated oven 3 and cooling tube 4, between pairs of brush rollers 8, 9, and finally through bath 10 where a layer of oil is applied. The oil layer subsequently burns as it approaches the molten glass. The wire may be stretched by imparting a greater velocity to roll 5 than to roll 2, and it may also be twisted. Oven 3 may be supplied with a neutral or reducing gas through stub 7; alternatively, the complete apparatus may be placed under vacuum. In modifications, the oven is gas-heated; a detergent solution is used instead of brushes 8, 9; and an oil-soaked ball of material through which the wire drawn is used instead of bath 10. Further, the oven may be extended laterally in order to accommodate complete wire nets, fabrics or meshes.

Title: Production of chromic oxide
IPC: C01G37/02
Filed: 1962-10-09
Abstract: The bulk density of chromic oxide is increased by heating Cr2O3 with a water-soluble, fusible, stable inert solid at a temperature above the fusion point of the solid but below the fusion point of Cr2O3. The Cr2O3 may be formed, either before addition of the solid or in situ, by the decomposition of ammonium chromate or dichromate; if in situ, the admixed solid should fuse at the thermal decomposition temperature, which is at above 200 DEG  C.  The mixture may be heated to 200-1500 DEG  C. 0.1 to 10% by weight of the solid, based on Cr2O3 may be used. Suitable solids are halides, nitrates and sulphates of the alkali and alkaline earth metals (including Mg), NaOH, KOH, KNO3, CuCl2, CuBr2, CrCl2, Na2Cr2O and other solids whose solubility in water is at least 1 g./1.  An aqueous solution of the solid may be mixed with Cr2O3. The ammonium chromate or dichromate may be prepared by reaction between an alkali metal chromate or dichromate and an ammonium halide, and some of the resulting alkali metal halide may act as the fusible solid.  The heat from exothermic decomposition of the ammonium chromate or dichromate may maintain the desired decomposition temperature.  After densification, the chromic oxide may be dispersed in water, preferably at below pH 6.4; the soluble solid dissolves, and the Cr2O3 is recovered.  The product may have bulk density of up to 2.6 g./ml.
