Patent GB-778207-A (GB)
Title: Process of producing carbon black and synthesis gas
Inventor: STOKES CHARLES ANDERSON
IPC: C09C1/48
Filed: 1954-01-27
Abstract: <PICT:0778207/III/1> Carbon black and a hydrogen-carbon monoxide mixture for the Fischer-Tropsch synthesis of liquid make hydrocarbons are produced by injecting into a furnace 14 a liquid hydrocarbon in vaporized or atomized form from a nozzle 28 and an annular stream of oxygen from a plurality of nozzles 26, a portion of the gaseous reaction product being recycled via inlet 32 as an annular stream around the hydrocarbon and oxygen streams, the remainder being freed from carbon dioxide and water vapour for use in the Fischer-Tropsch synthesis.  Gaseous reaction product may additionally be recycled via inlets 36 and by mixing with the oxygen and vaporized or atomized liquid hydrocarbon before injection.  The recycle gas may be dried or carbon dioxide and water vapour may be added.  The make hydrocarbon may be preheated residual oil (properties specified) atomized by a suitable gas or by pressure, or gas-oil vaporized alone or in admixture with a suitable gas.  Suitable gases specified are recycle gas and hydrocarbon gas produced in the Fischer-Tropsch synthesis, e.g. a mixture of methane and ethane.  The make hydrocarbon may also be a liquid product of the Fischer-Tropsch synthesis, or gas-oil producer, together with gasoline, by cracking such a product.  1 vol. of oxygen, 2 vol. of vaporized hydrocarbon, and 4 vol. of recycle gas may be employed.  Specification 719,221 is referred to.

Title: Distribution classifier
IPC: B07C5/28
Filed: 1952-01-30
Abstract: 696,016. Electric control systems. EXACT WEIGHT SCALE CO. Jan. 30, 1952 [Feb. 2, 1951], No. 2485/52. Class 40 (i) [Also in Group XIX] The frequency distribution for a particular variable on a production line, e.g. the weight deviation of packages from a standard, is determined by translating the weight deviations into corresponding voltages and classifying the voltage magnitudes by means of a plurality of identical electronic cells arranged to actuate counters individual to different voltage magnitudes. As shown, each cell comprises a thyratron 1, an associated relay 36 operating a switch 3, and a counter 2. The thyratrons are biased from a battery 21 through individual potentiometer 4, and, also from the A.C. supply lines 10, 11 through a peaking transformer 8. The potentiometers 4 are set so that the thyratrons will fire at successively increased values of the signal voltage applied to the lines 5, 6. A normally open keying switch 52 is closed for a period by a photoelectrically or otherwise operated relay 56, each time a package passes from the weight checking machine, to energize all the thyratron anodes. The signal voltage amplitude, proportional to the weight deviation of the package from normal, fires a corresponding number of the thyratrons starting from the left. The relays 36 are connected across the anodes of their adjacent thyratrons so that only the relay 36 associated with the last tube to fire, i.e. next to the first unfired tube, operates its switch 3 to actuate the associated counter 2 over contact 43. Over its contact 42, the switch 3 prevents firing of succeeding thyratrons and over contact 44 it short circuits the relay 36 associated with the preceding thyratron to prevent any registration thereby. Consequently one counter only operates corresponding to the magnitude of the signal. voltage. Each end thyratron cell registers all packages classified therein and extending there beyond.

Title: Improvements in or relating to anti-friction bearings
IPC: F16C33/64
Filed: 1945-02-01
Abstract: 601,973. Making compound race-rings ;  casting. KENDALL, G. H. Feb. 1, 1945, No. 2563. [Classes 83 (i) and 83 (ii)] In a process of making a bearing race-ring, an undersized ring having an unfinished raceway has bonded to it a more workable material to bring the ring to the required size, after which the raceway is finished as by grinding and lapping; Raceways 12 and 13 are formed in rings 10 and 11 of a hard, difficultly workable alloy. A layer of a more workable metal or of a plastic is bonded to each of the surfaces 18, 19 and if desired also to the whole or part of the side surfaces of the rings 10 and 11, as shown in Fig. 2. The softer and more workable material may be extended as at 37, Fig. 5, to form a mounting support. After the formation of the outer softer covering, the sides of the bearing ring are brought to the required finished size by pressing between dies 40, 43 and the outer surface 22 by means of a sleeve 44 moved downwardly over the surface, Fig. 6. The edge of the softer material may be spun over at 30, to hold a dust shield 29, Fig. 4. The softer material may be bonded around the hard metal insert 10, 11 by die-casting or centrifugal casting in a mould, part of which is shown at 50, 51 and 52, Fig. 5, by the moulding of a suitable plastic, by moulding and sintering a metal powder, by electrolytic deposit or by building-up by metal spraying. For comparatively large bearings and where the softer material extends only over the curved surface of the ring, the backing may be bonded to the insert by brazing. In a modification, the rings are produced from a composite tube by cutting transversely and leaving the outer softer layer of greater width than the inner hard layer. Specification 570,141 is referred to.

Title: Titanium base materials
IPC: C22C14/00
Filed: 1958-01-27
Abstract: Titanium alloys which have an all alpha or a mixed alpha-beta p microstructure at room temperature contain at least 2,5% of alloying metal which stabilise the alpha phase, optionally beta-stabilising alloying metal in amount less than that which would impart an all beta-structure, and hydrogen in amounts of 30-150 parts per million to confer high resistance to embrittlement and failure under slowly applied or sustained loads below the ultimate strength of the alloy. The alpha-promoting constituent may be 2,5-12% of tin and/or aluminium and the beta-promoting constituent 4-8% of manganese, mobybdenum, vanadium and/or copper.

Title: Direction determining method
IPC: G01S1/30
Filed: 1972-01-20
Abstract: 1336972 Radio navigation INTERNATIONAL STANDARD ELECTRIC CORP 20 Jan 1972 [26 Jan 1971] 2746/72 Heading H4D The invention is based on the received phase differences # 1 ...# v ... # n  between transmissions from n (n being even) spaced radiators of increasing space increment d and those from a reference radiator. According to one aspect the receiver direction #<SP>1</SP> is determined from the relationship sin #<SP>1</SP> = (2P)/(#n<SP>2</SP>d/#) where # is the radiation wavelength for sequential transmission or mean wavelength in the case of frequency multiplexing and According to another aspect magnitudes #<SP>11</SP> 1 ... #<SP>11</SP> v ...#<SP>11</SP> n  are calculated according to sin #<SP>11</SP> #  = # # /(2#vd/#) and #<SP>1</SP> is the maximum value of the #<SP>11</SP>s. In both aspects the radiations are coherent pulse pairs; in an embodiment the first pulses of the pulse pairs are radiated successively by the radiators 1 to n whilst all second pulses are radiated by the reference aerial, and the receiver incorporates the necessary delay of first pulses to afford phase measurement. The invention is particularly described for elevation angle, the radiating array being vertical; and it is illustrated how errors due to ground reflexion are reduced. In the first method weighting factors may be applied as described in the Specification.
