Title: Process for the destructive hydrogenation of liquid hydrocarbon material
IPC: C10G47/00
Filed: 1937-05-06
Abstract: 500,282. Destructive hydrogenation of carbonaceous materials ; Diesel fuels. POTTS, H. E. (International Hydrogenation Patents Co., Ltd.) May 6, 1937, No. 12917. [Classes 32 and 91] Diesel fuel is made by subjecting solid or liquid carbonaceous materials to destructive hydrogenation in the liquid phase, separating from the product gasoline, middle oil, and heavy oil, subjecting the middle oil fraction or a part thereof to a hydrogenating destructive hydrogenation to form an oil boiling between 180 and 300‹ C., and blending therewith 2 to 25 per cent by weight of the heavy oil fraction boiling above 325‹ C. produced in the first stage, or of a heavy unhydrogenated oil such as mineral oil or tar oil freed from asphalt by treating with low boiling hydrocarbons. If sufficiently free from asphalt small amounts of the initial untreated oil may also be added. The first hydrogenation step is effected at 300 to 350‹ C., under pressures above 20 atmos. and preferably between 200 and 750 atmos., and in the presence of catalysts consisting of elements of Group 6 or compounds thereof or of iron, zinc or tin. Sulphuric acid halogens or hydrogen halides or compounds forming these may be present, for example ammonium chloride, carbon tetra chloride, or chloroform. The second stage hydrogenation is effected in vapour or vapour-liquid phase and under strongly hydrogenating conditions, preferably at 350 to 420‹ C., at about 200 atmos. pressure, and with hydrogenating catalysts especially tungsten or molybdenum sulphide supported upon carriers preferably pre-treated with fluorine or hydrogen fluoride which corrode silicates. The heavy oil fraction obtained in the first stage may be treated with bleaching earth or may bo hydrorefined to remove asphalt before blending with the hydrogenated middle oil. In an example, an ash-free coal is pasted with an equal weight of a heavy oil, and the mixture is treated with hydrogen at 460‹ C. under 300 atmos. pressure in the presence of tin oxalate and ammonium chloride. After removing the pasting oil, the hydrogenated product is separated into gasoline, middle oil, and heavy oil. The middle oil boiling at 170 to 340‹ C. is treated with hydrogen at 390‹ C. under 200 atmos. pressure in the presence of tungsten sulphide stationarily contained in the treating chamber or distributed in the oil. The hydrogenated middle oil, after removal of' gasoline, is blended with the hydrogenated heavy oil from the first stage to form a Diesel fuel. The gasoline from the first and second stages maybe mixed to form a light fuel.

Abstract: 396,182. Electric signalling systems. LANDIS & GYR AKT.-GES., 1, Hofstrasse, Zug, Switzerland. May 5, 1932, No. 12927. Convention date, May 11, 1931. [Class 40 (i).] Measurements, especially on electricity meters, are made at a distance by impulses produced on variation of the capacity of a condenser, the rotor of the condenser being actuated by the meter rotor and having no external electrical connections. An electricity meter is geared to the movable plates 12, 13 of a condenser, the fixed plates 8 .. 11 being connected to an amplifier 3 fed with alternating- current and supplying the distant coil 4. The amplified current energizes a relay coil 20 in series with the coil 4 so that a cyclic operation of the condenser occurs. The movable plates of the condenser may have jewelled bearings, and the number of measurement impulses per revolution may be varied. The connections may be such that in one position of the condenser plates the amplified output current is interrupted, the contact 17 of the relay being then returned by spring tension. Fig. 2 shows an arrangement wherein the input and output of the amplifier are actuated by motor switching mechanism, 'the output 19 energizing a relay coil 21 which trips a pawl 35 making contacts 34, 36 to the motor circuit 26. The changeover device comprises a contact 'section 37 co-operating alternately with spring contacts 39, 40, the measurement impulse being transmitted through a contact 43 connecting the distant coil 4. Specification 342,681 is referred to. The Specification as open to inspection under Sect. 91 describes an arrangement, Fig. 5 (cancelled), in which the coupling takes place between coils 50, 51, coil 51 being connected through capacity couplings 56, 57 to a high frequency source and being rotated by the meter gearing. Inductive currents which may be amplified are supplied to a relay 21 which may actuate a motor switching mechanism. The coils 50, 51 may be located in the grid and anode circuits of a thermionic oscillator. This subject-matter does not appear in the Specification as accepted.

Title: Line scanning equipment for telecommunication exchanges
IPC: H04Q3/545
Filed: 1969-03-12
Abstract: 1,212,143. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 12 March, 1969 [16 March, 1968], No. 13026/69. Heading H4K. A scanning arrangement in a telecommunication exchange comprises a line scanning matrix, a storage matrix which stores the states of the lines in accordance with the preceding scan, a comparator which upon detection of a change in the state of a line being scanned signals to a central control equipment, and test equipment including a register arranged to receive from the central control the address of a line to be tested and a coincidence network which compares this address with the address of the line currently being scanned and in the event of a match due to that line being scanned transmits the state of the line to the central control. The arrangement shown comprises a line scanning matrix AM and a storage matrix SM which are scanned simultaneously point by point by counters SZ and ZZ and decoders SD and ZD stepped regularly by pulses applied at T1. As each line is scanned a comparator Vgl compares the corresponding points of the matrices and in the event of a change of state sends a " 1 " or " 0 " bit in accordance with the change of state to a circuit RB which also receives the row and column addresses of that line. This data is forwarded to the central control over a bus MLB. If due to a fault or breakdown a signal is lost the central control can request the condition of a particular line by inserting the address of that line in a register ARg. When the scanner next scans that line every one of a series of AND gates E responds simultaneously, and when a timing pulse arrives at T2, an AND gate A is opened setting a flip-flop FF1 enabling a gate C. A timing pulse T3 opens this gate to pass the state of the scanned line to a flip-flop FF2 and a subsequent timing pulse at the T1 input of a gate D sets a flip-flop FF3 which indicates to the central control Z that flip-flop FF2 is set to the state of the wanted line. FF1 and FF2 are reset by the central control. Another embodiment in which the test circuit P is common to a plurality of scanning arrangements DA and is located at the central control is detailed. Transmission of addresses from the scanning arrangements DA and from the central control to the test circuit are effected in binary coded form and comparison at the test circuit is effected using coded signals.

Title: Separating n-propyl alcohol from secondary butyl alcohol by azeotropic distillation
Filed: 1951-06-06
Abstract: n-Propyl alcohol is separated from secondary butyl alcohol by distilling the mixture with water and an aliphatic or cycloaliphatic hydrocarbon which forms a ternary azeotrope with n-propyl alcohol and water; the vapours of the ternary azeotrope distilling over are condensed, the condensate is allowed to settle into two layers (a hydrocarbon layer and an aqueous layer), and the aqueous layer is separated and distilled to obtain purified n-propyl alcohol (in the form of its azeotropic mixture with water).  Suitable hydrocarbons are cyclohexane, n-octane, methyl cyclohexane and 2, 5-dimethyl hexane.  The process may be applied to the products of the partial oxidation of butane or mixtures of propane and butane.  A crude mixture (100 parts) containing 45.3 per cent. of n-propyl alcohol 14.2 per cent. of secondary butyl alcohol and 40.5 per cent. of higher boiling alcohols, such as isobutyl, n-butyl and amyl alcohols, as well as small amounts of oxides and acetals, is fed to the reboiler of a 45-plate column together with water (400 parts) and methylcyclohexane (100 parts). The reboiler is heated and the mixture distilled.  The hydrocarbon layer, which separates from the condensed distillate, is decanted and returned to the column as reflux.  The distillation is continued until 40 per cent. of the alcohols in the reboiler has distilled over.  The aqueous part of the distillate comprises an approximately 25 per cent. aqueous solution of n-propyl alcohol, which is distilled to give n-propyl alcohol (of a purity greater than 99 per cent.) in the form of its azeotropic mixture with water.  On continuing the distillation, the secondary butyl alcohol ternary azeotrope distils over, and separates into an aqueous and a hydrocarbon layer.  On distilling the aqueous layer, purified secondary butyl alcohol is obtained in the form of its azeotropic mixture with water.
