Title: An improved process for the conversion of mixed iso- and normal butanes to liquid hydrocarbons
IPC: C07C9/16
Filed: 1938-01-25
Abstract: 509,160. Converting gaseous hydrocarbons into liquids. STANDARD OIL DEVELOPMENT CO. Jan. 25, 1938, No. 2405. Convention date, March 16, 1937. Drawings to Specification. [Class 2 (iii)] Mixtures of normal and iso-butanes are separated into a fraction rich in normal butane, which is converted into gasoline by thermal non-catalytic polymerization, and a fraction rich in isobutane which is subjected to thermal conversion to olefines and then to catalytic polymerization to gasoline. Refinery C4 cut containing paraffins and olefines may be utilized together with the butane mixture by fractionating into normal and iso-hydrocarbons which are thermally and catalytically polymerized respectively or by feeding direct to the catalytic polymerization zone and passing the residual C, hydrocarbons to the fractionator for the butane mixture. The product of the catalytic polymerization may be hydrogenated with the hydrogen-containing gas evolved in the thermal conversion of the isobutane after removal of C2 and C3 olefines and, if desired, after enrichment in hydrogen by reacting the paraffin content with steam at 600-1800‹ F. in presence of nickel with or without carriers and difficultly reducible oxides. The isobutane fraction is cracked at 1150-1400‹ F., or catalytically dehydrogenated at 900-1100‹ F. using a Group VI oxide or sulphide, if desired with other oxides or carriers. Isobutene and unconverted isobutane, in some cases together with C3 hydrocarbons, are separated by condensation and treatment of the gases with an absorption medium, and are polymerized, for example, with sulphuric acid.. The polymer is fractionated and the dimer fraction hydrogenated. The normal butane fraction of the feed is heated at 800-1200‹, e.g. 1025‹ F., and at least 500, e.g. 1600 lbs./in.<2> and the product fractionated to separate polymers of gasoline type, C3 and C4 gases which are recycled to the thermal polymerization zone or, if rich in olefines, to the catalytic polymerizer, and C, and lighter gases. The residual gases from the cracking of the original isobutane fraction are treated in one or two stages with sulphuric acid, preferably with 80-90 per cent acid below 95‹ F. to absorb propene, and with 75-80 per cent acid at 200-265‹ F. to absorb ethylene, and the residue, if desired after enrichment in hydrogen as described, used to hydrogenate the di-isobutene. Ethyl, propyl and butyl sulphates obtained by the sulphuric acid absorption may be mixed and heated to 200- 300‹ F., giving iso-hydrocarbons of 6, 7, 8 or more C atoms. The catalytic polymerization is preferably performed at at least 400 lbs. /in.<2>, e.g. with phosphoric acid at 150-350‹ F., or 60-75 per cent sulphuric at 150-300‹ F. or, if considerable-propene is present, with 65-80 per cent sulphuric above 200‹ F.

Title: Improvements in and relating to Electric Motor COntrol Systems.
IPC: B66B1/08
Filed: 1917-02-20
Abstract: 113,473. British Thomson - Houston Co., (General Electric Co.). Feb. 20, 1917. Systems for continuous-current motors only; electric braking.-A series motor used for hoisting &c. has reversing means and connexions whereby the field winding may be connected in shunt to the armature during lowering to form a dynamic braking circuit, and the connexions of a resistance in this circuit are controlled bv an electrcmagnetic switch responsive to the speed of the motor. The connexions of the armature A and series field F to the controller C are shown in Fig. 1. With the controller in its " off " position, the motor is connected for dynamic braking and the resistances R<1>, R<2> are connected in the circuit. The switch 3 controlling the resistance R<2> is operated by a solenoid consisting of two differential sections 4, 5 connected with resistances 6, 7 across the line 1, 2, while the junction of the sections is connected to the movable contact of the resistance R<1>. Part of the resistance R<1> is left permanently in the circuit to ensure the proper speed-torque characteristics for lowering and the resistances R<1>, R<2> together are large enough to protect the armature against excessive rushes of current. For hoisting, the controller is moved to the left, the brake coil R is energized to release the brake, and the resistance R is gradually short-circuited while the motor runs as a series motor. For lowering, the controller is moved to the right, and circuits are made as shown in Fig. 2. A complete circuit is formed of the armature A, field coil F, brake coil B, resistances' R<1>, R<2>, and a part of resistance R dependent on the position of the controller. The section 5 of the actuating winding of the switch 3 with resistances 6, R<1> is connected across the armature and its current is responsive to the back electro-motive force of the motor, while the section 4 with resistance 7 is connected across the resistances R<2>, R. The difference in ampereturns between the two sections 4, 5 is not sufficient to lift the switch 3 although the controller may be moved quickly. The resistance R<2> is therefore left in circuit as a protection against current rushes. As the motor speeds up, the voltage on the section 5 rises and that on the section 4 falls until the switch 3 responds and short circuits the resistance R<2>. The resistances 6, 7 may be varied by the controller so that the switch 3 closes with different armature current values during increasing speeds and decreasing speeds. In a modification, the conductor from the junction of the sections 4, 5 includes contacts of a relay 9, Fig. 4, which can only close when the armature current drops to a predetermined value. After closure of the relay 9, the switch 3 is subject to the differential control of the sections 4, 5 as before.

Abstract: 912,142. Telephone instruments. PHILIPS ELECTRICAL INDUSTRIES Ltd. Jan. 25, 1960 [Jan. 28, 1959], No. 2630/60. Class 40 (4). In an electro-mechanical transducer particularly for use as a loud-speaker, a hollow cylindrical permanent magnet 4 attached by plate 3 and rod 2 to a diaphragm 1 is arranged so that it can move freely in an axial direction in the small annular space between two coaxial non-magnetic stationary conductors 5, 6, e.g. of copper, having axially extending slits 7, 8 (Fig. 2). The current supply terminals are at the walls of each slit and the current in the two conductors are in antiphase so that the fields in the annular space are in the same direction. Substantially all the lines of force from magnet 4, which is made, for example, of PtCo, length 10 mm. and wall thickness 2 mm., pass through the copper conductors if these are about 1 mm. thick. The total absence of iron in the magnetic circuit reduces asymmetries in the circuit which might result in lateral forces and hence unfavourable deformation of the response curve. Stripshaped conductors may replace the copper sleeves or wire wound coils may be used. Specification 469,093 is referred to.
