Title: A process for the production of hydrocarbons suitable as fuel for internal-combustion engines
IPC: C10G1/10
Filed: 1937-02-01
Abstract: Hydrocarbon mixtures suitable for motor spirit are obtained by subjecting rubber latex and similar materials to distillation, preferably below 520 DEG  C., with or without the addition of gases, vapours, chemical reagents or catalysers.  Other products of the process are "a liquid having properties particularly favourable for animals," a liquid for injection into timber to protect it against atmospheric effects and insects, a bituminous residue suitable for roadsurfacing and waterproofing, and a decolorizing and absorbent charcoal.  Combustible gases evolved may be in part condensed and added to the motor spirit and in part used to supply heat to the distillation.  In an example latex is distilled with a catalyst up to 520 DEG  C., giving a liquid fraction B, condensable volatiles C, combustible gases, active carbon, and water.  The p  fraction B is distilled forming fractions B\sv and B" separating below and above 150 DEG  C. respectively.  The latter fraction is cracked to give a liquid fraction B1, condensable volatiles C1, combustible gases and active carbon.  The fraction B1 forms a further fraction B\sv1 below 150 DEG  C., while the residue B"1 is cracked giving a liquid B2, condensable volatiles C11, combustible gases, and active carbon. Further distillation of the liquid B2 gives fractions B\sv2 and B"2 below and above 150 DEG  C. respectively.  The fractions B\sv, B\sv1, and B\sv2 are united with the condensable volatiles C, C\sv and C" and yield, after distillation with calcium salts and refining with sodium, hydrocarbon products for use in internal-combustion engines. These products may be mixed with ethyl and methyl alcohol, gasoline, benzoline, acetone, and ether.

Abstract: 338,444. Mond, A. L., (Soc. Chimique de la Grande Paroisse Azote et Produits Chimiques). Jan. 28, 1930. Chemical manufacture, furnaces for.- A jet of oxygen or air enriched with oxygen is impinged on a restricted area of the surface of a, bed of coke to produce a high temperature zone in which refractory substances such as silica, alumina and calcium phosphate may be volatilized and caused to react. The sheet-iron crucible A contains a bed of coke forming a hearth F to which oxygen or air enriched with oxygen is supplied by a tube B which may be suitably cooled. Coke together with the materials to be volatilized or combined is supplied to the hearth by a distributor E and chute D, and the ashes of the coke together with the other materials are volatilized and carried off through a pipe H with the products of combustion, which comprise carbon dioxide practically free from monoxide and with a slight excess of oxygen. The fine powders are separated from the combustion products by known methods. Silica, or ferric oxide employed for polishing metals may thus be reduced to a fine powder, and silica, or alumina be made to react on calcium phosphate for the production of calcium silicate or calcium aluminate and oxides of phosphorus.

Abstract: 1,074,923. Axial-flow blowers and pumps; turbines. SULZER BROS. Ltd. Jan. 26, 1965 [Feb. 14, 1964], No. 3427/65. Headings F1C and F1T. [Also in Division F2] In a rotary turbine, blower or pump, e.g. a circulatory blower for nuclear reactor plants, the rotor shaft 2 is sealed during normal running by a seal 5 mounted in a housing 7 which is axially slidable in a main housing 8 from its normal operative position to an inoperative position when the shaft is stationary in which a part on the shaft, e.g. the rotor 1, sealingly engages a stationary part 9 of the machine, the housing 7 being held in its operative position by retaining means including a displaceable spacer element 20 movable by remote control means to a position permitting movement of the housing 7 to its inoperative position. The seal housing 7, in which the shaft journal bearings 3, 4 and thrust bearing 6 are mounted, is located in the main housing 8 by a number of retainers each comprising a bolt 10 secured to the housing 8 and having a piston portion 12 in a cylinder 13 abutting a flange 15 of the housing 7. Spacer elements 20 urged inwardly by springs 22 are normally clamped between the cylinder 13 and a second cylinder 16 by a nut 11 on the bolt 10. One end of a piston 17 in the cylinder 16 engages an inclined surface 21 on the elements 20. Hydraulic pressure fluid can be supplied to the cylinders 13 and 16 through conduits 14 and 18 respectively. Hydraulic cylinders 23 on the housing 7 are connected to a source of pressure fluid through conduits 25 and have pistons 24 that bear against the end face 26 of the housing 8. During normal operation, the housing 7 and shaft are moved to the right so that the rotor is out of contact with the seal part 9, the flange 15 of housing 7 then being held against the housing 8 as shown in Fig. 2. When the blower is stopped the housing 7 and shaft are moved to the inoperative position shown in Fig. 1 by first, admitting pressure fluid to the cylinders 13 through conduits 14, to stretch the bolts 10 and release the clamping pressure on the elements 20, then supplying pressure fluid through conduits 18 to move the pistons 17 and force the elements outwardly clear of the cylinders 16 and finally, exhausting the pressure in cylinders 13 so that the housing 7 can move to the left under the influence of the pressure of the fluid circulated by the blower. If such pressure is insufficient the housing 7 can be moved to the left by pressurizing the cylinders 23 via conduits 25. The pressure in the cylinders 16 is then released. When it is desired to return the housing 7 to its operative position cylinders 13 are pressurized so that the housing 7 is moved to the right and the bolts 10 stretched whereby the elements 21 can be returned by the springs 22 to their positions between the cylinders 13 and 16. Hydraulic pressure is provided by a motor driven oil pump 37 and the supply to end exhausts from the cylinders 13, 16 and 23 of hydraulic pressure is controlled by electromagnetic valves 49 and 50, 51 and 52 and 42 respectively.

Title: Improvements in or relating to protective arrangements for a.c. electric circuits
IPC: H02H3/30
Filed: 1926-02-08
Abstract: 270,410. Reyrolle & Co., Ltd., A., and Biles, R. W. Feb. 8, 1926. Cut-out arrangements.-In a Merz-Price protective system, in order to dispense with an auxiliary source of current for tripping the circuit-breakers on fault, the out-of-balance current in the pilot wires operates relays to short-circuit or otherwise modify the pilot circuit so as to localize the circuit containing the trip coils and adjacent current transformer secondaries. This circuit is thus relieved of the impedance of the pilot wires and of the apparatus at the other end, and the current in it is effective to produce the necessary tripping. In the arrangement shown in Fig. 1, with a reversed-delta connection of current transformers, the coils C of relays are included in the pilot wire circuit. When, on fault, these relays close, they short-circuit the pilot wires by means of the contacts C<4>, and at the same time, by means of the contact-arms C<1>, connect the current transformer systems to the trip coils D which in the normal position of the relays are open-circuited. A diverter relay E for lowering the sensitiveness of the pilot wire relay for straight-through currents may be connected across the coil C. In other arrangements, the trip coil may be normally short-circuited by the relay and open-circuited when the relay operates on fault. In the arrangement shown in Fig. 6 with three pilot wires a single tripping coil J in one of the earth wires is normally short-circuited by a circuit containing the three contacts K, K<1>, K<2> of three relays G. G', G<2> each in a pilot wire circuit. When, on fault, any one of the relays operates, its contacts are changed over so as to short-circuit the pilot core H<1> with one of the other pilot cores and to bring the tripping coil J into the circuit so localized containing two of the transformer secondaries with the corresponding two relay coils. In a modification of this arrangement three tripping coils, one in each phase, are employed. Specification 258,961 is referred to.
