Patent GB-452429-A (GB)
Title: Process for the production of benzines from middle oils by destructive hydrogenation
IPC: C10G47/00
Filed: 1935-02-20
Abstract: Benzines are produced from middle oils containing phenols by separating the middle oil by fractionation into two fractions, the lighter of which boils up to 275 DEG  C., subjecting the lighter fraction to a mild destructive hydrogenation at 370--440 DEG  C. in presence of catalysts e.g. compounds of molybdenum and zinc so that the phenols are reduced, separating benzines from the products which are then subjected to an "aromatizing" destructive hydrogenation at 500--550 DEG  C. in presence of similar catalysts, subjecting the heavier fraction of the middle oil to a splitting destructive hydrogenation at 370--440 DEG  C. in presence of hydrogenating catalysts, and if desired mixing the benzines obtained from the separate treatments.  The products from the aromatizing treatment may be recycled to that stage, heavy residues being removed and part of the products obtained may be mixed with the fraction which is subjected to the splitting treatment.  A middle oil obtained by the destructive hydrogenation of brown coal is separated into a fraction boiling up to 275 DEG  C. and a heavy fraction boiling from 275 to 325 DEG  C. The light fraction is led in the gaseous state at 400 DEG C. and 200 atms. over compounds of molybdenum and zinc.  The product freed from benzines by distillation is then treated at 500--550 DEG C. in presence of a similar catalyst.  The heavy fraction mixed with a portion of the product obtained above is led at 400 DEG  C. and 200 atms. over tungsten sulphide and the benzines obtained from the treatments are blended.

Abstract: 739,951. Automatic exchange systems. AUTOMATIC ELECTRIC LABORATORIES, Inc. Feb. 25, 1954 [March 10, 1953], No. 5587/54. Class 40 (4). A double-wiper hunting switch is driven by a shunt-field motor magnet the two windings of which are connected to the two test wipers so that stepping continues as long as both wipers encounter busy or unwanted outlets. A system employing finder-hunter links is described, the finder 102 and hunter 200 operating simultaneously and being driven by shunt-field magnets M150, M270. When a call occurs, line relay R120 removes ground from the test terminal and grounds start wire 171. Relay R330 in the allotter energizes in series with magnet M310 followed by relay R340 and connects up start relay R210 in the allotted link. Magnet M150 now steps the finder 102 until test wiper 166 or 168 encounters an ungrounded outlet, when the corresponding switching relay R130 or R140, hitherto short-circuited, pulls up in series with the magnet. At the same time, magnet M270 steps the hunter 200 in search of an idle outlet and switching relay R230 or R250 pulls up. The operated switching relay R130 or R140 grounds test wiper 166 or 168 to energize cut-off relay R110, and both operated switching relays are held by ground fed back from the switch ahead. Magnet M310 steps the allotter to preselect the next idle link. If all links are busy, however, relay R320 is released to prevent useless hunting. When the connection is released, the hunter 200 steps to normal. Specification 170,385, [Class 40 (iv)], is referred to.

Abstract: 966,352. Turbines; centrifugal pumps. L. BOLKOW, [trading as BOLKOW-ENTWICKLUNGEN K.G.]. Feb. 12, 1963 [Feb. 13, 1962], No. 5665/63. Headings F1C and FIT. [Also in Division F2] In an embodiment, a shaft 11 has a gas turbine rotor 12 and a pump impeller 13 thereon and is mounted, by means of a roller bearing 14 and a ball bearing 15, in a housing 8. A sliding-ring packing 17 is positioned on the turbine side; a labyrinth packing 18 is positioned between the bearings 14, 15; and a labyrinth packing 22 is positioned between the bearing 15 and the impeller 13. The inlet side of the pump impeller 13 communicates, via a bore 28 and a conduit 29, with a lubricant-tank 60. The lubricant pressurised by the impeller 13 is passed, through a bore 62, a distributor point 63 and conduits 61, 64 to a consuming unit 65. A lubricant pipe 52 leads to a regulating valve 2 which is connected by a lubricant pipe 53 and bore 70, in a housing 25 to the packing 17. The valve 2 is also connected, via a pipe 51 and bores 71, 81, with a clearance space 72, the bore 81 being in the turbine inlet guide blade ring 24. A starting regulating valve 2b may be included in the circuit. In use, lubricant is supplied from the tank 60 to the pump via the pipe 29 and the bore 28 and is forced by the impeller 13 to the distributor point 63, where part of the lubricant is distributed to the unit 65 and part is distributed to the valve 2 so as to have the lubricant pressure reduced. The lubricant leaves the valve 2 and passes, through the pipe 53 and the bore 70, to the packing 17. The turbine working medium in the space 72 effects a pressure on the other side of the packing 17. Thus the latter receives pressure at each side thereof and no flow takes place therethrough. The lubricant flows from the packing 17, through the bearing 14, the packing 18, the bearing 15 and the packing 22, back to the impeller 13. In a modification, the packing 17 comprises two sliding rings having an annular space therebetween supplied with inert gas, the pressure of which is regulated by a valve 2. In another modification, the two sliding rings are replaced by two labyrinth packings.

Abstract: 452,299. Solenoids. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. Feb. 22, 1935, No. 5733. Convention date, Feb. 23, 1934. [Class 35] [See also Group XXXVII] A magnet coil, particularly a blow - out coil for a vacuum switch, comprises a substantially-flat, helically-wound conductor 17, which is biassed against compressive and bursting stresses and maintained in proper spacing, by means of several series of balls 24, cylinders, or wedges, disposed around the coil in hemispherical recesses 17<1>. The coil is electrically connected at the ends to a disc 21 and to a flange 9 which is slotted at 20 to minimize eddy-currents. The material for the balls must be strong and have a low coefficient of expansion, a suitable one being the glass known under the Registered Trade Mark " Pyrex." The coil is so proportioned that the compressive force is greater than the force per turn tending to enlarge the coil diameter, so that notwithstanding current increases, the balls will be kept in their recesses. A ceramic cylinder 25 takes a part of the compressive force.
