Title: Process for the simultaneous reduction of ores and conversion of carbonaceous materials into hydrocarbons of low boiling point
IPC: C22B5/00
Filed: 1929-07-25
Abstract: 339,276. Fohlen, J. L. July 25, 1929. Dry processes of extracting nickel and other metals.-Ores are reduced to metals and carbonaceous materials are hydrogenated to form products suitable as fuels in the same operation, by first reducing the ore in the presence of carbonaceous materials or their distillation products and hydrogen heated to about 350-400‹ C. the temperature being then allowed to fall to 150-300‹ C. whereupon the gaseous products of the reaction are hydrogenated by contact with the freshly reduced metal. Lignite is distilled in a rotary furnace 1 in the presence of hydrogen, water gas etc. introduced through a pipe 22, the cokeformed being collected in a receiver 13, where it is separated from ammoniacal liquors and pitch in a grid 16. The products in the gaseous state are passed through a pipe 25 into a second retort 2 heated to 500‹C into which garnierite is fed through a shuttered hopper 5. Hydrogencontaining gases are fed in through a pipe 23 and the garnierite is converted to nickel sulphide which is collected on a grid 17. Materials containing sulphur e.g. calcium sulphide may be added if the lignite gases do not contain sufficient sulphur. The nickel sulphide is reduced to nickel oxide which is fed into a third retort 3 supplied with gases from the retort 2 by a pipe 26 and with hydrogenating gases through a pipe 24. The temperature in the first portion of the retort 3 is maintained at 300-450‹ C. and the nickel oxide is reduced to nickel. In the second portion of the retort the temperature is allowed to fall to 300-150‹ C. and the carbonaceous products are hydrogenated by contact with the freshly reduced metals which is collected on a grid 18. The volatile products pass off through a pipe 27 and are condensed and washed in the usual manner. The process may be applied to the production of hydrogenated products from anthracene in which case only two retorts need be used the anthracene &c. being fed in through the hopper 5.

Title: Control rod driving systems for nuclear reactors
Inventor: HANSON DOUGLAS OLIVER
IPC: G21C17/12
Filed: 1966-05-24
Abstract: 1,127,390. Controlling reactors. NUCLEAR POWER GROUP Ltd. 11 May, 1967 [24 May, 1966], No. 23134/66. Heading G6C. [Also in Division H2] A control rod driving system includes means for determining and comparing automatically and continuously, during control rod movement within the reactor, the position of each control rod in a group in relation to the other rods of the group, or the position of each group of control rods in relation to the other groups, which means are also adapted to arrest movement of one or more control rods or groups of rods automatically when it or they become displaced relative in advance of one or more other rods in the group or one or more other groups, in excess of a predetermined amount. By way of example, a plurality of 3-phase induction motors la, 1b, 1c, each connected to a power supply 2 at mains frequency, drive pulleys 3a, 3b, 3c through electromagnetic clutches and reduction gearing 4a, 4b, 4c, in the manner described in Specification 967,513. The drive to each pulley is through a worm and wheel so that if the clutch is energized but the power supply to the motor is cut off, the rod is held in position and does not fall into the reactor. It can only fall into the reactor under its own weight in an emergency condition when the clutch is de-energized. The control rods A, B, C are supported from their pulleys by flexible members, such as cables 6a, 6b, 6c. Control rod position sensing devices 7a, 7b, 7c operate in conjunction with the cables and feed signals representative of the positions of the rods to an automatic control device or computer 8. This continuously compares the positions of the rods and should the position of one differ from that of one or more of the others by more than a predetermined amount, feeds a signal to the corresponding control contact 9a, 9b or 9c to cut off the power supply to the motor concerned. The positions of the rods vary in practice because of varying amounts of slip in the motors. If as in the case shown, the rod B has reached a position in advance of a defined limit band between line XX and line YY, the device 8 operates contact 9b to cut off the power supply to motor 1b and the rod B comes to rest until the limit band moving upwards at the speed of the slowest rod is in a position where rod B again lies within the limit band, at which point the device 8 closes contact 9b and the power supply is restored to motor 1b. The contacts 9a, 9b, 9c are operated on a fail-safe basis so that should the signals from the device 8 be cut off, the supply to the motors 1a, 1b 1c is cut off and the rods come to rest. An overriding switch 10 enables manual control to be substituted for automatic control.

Abstract: 1,112,763. Photo-electric direction finders. BRITISH AIRCRAFT CORPORATION (OPERATING) Ltd. 8 June, 1965 [5 June, 1964], No. 23432/64. Heading H4D. [Also in Division G3] A satellite has means by which it can be space-stabilized including two groups of telescopes, one group at each end of a rotatable shaft, the telescope axes being parallel to the shaft axis and the telescopes receiving illumination from a star field through mirrors or prisms and directing it on to photomultipliers through means which scan successive parts of the field so that changes in the output waveform of the photomultiplier indicate changes in telescope attitude. As described, four interchangeable telescopes are fixed at each end of a shaft so that they are symmetrical about the axis of the shaft and parallel to it. The shaft is rotatable about its axis relative to the satellite. Light from stars is deflected into each telescope from a different direction by mirrors or prisms and within each telescope a lens driven eccentrically by an electric motor moves the image over a modulator mask having alternate transparent and opaque sectors to produce from a photomultiplier tube a signal representative of the magnitude and direction of attitude error. Each telescope and its photomultiplier are arranged side by side and the light suitably deflected to produce a compact arrangement. The error signals correct the attitude of the satellite about perpendicular axes by controlling the operation of fluid jets or the rotation of inertia masses about perpendicular axes which may correspond to the axis of the shaft and an axis about which an observational astronomical telescope carried by the satellite may be adjusted. The observational telescope may also be adjusted about a perpendicular axis by rotating the shaft carrying the control telescopes about its axis. The plurality of control telescopes provides continuity of control despite the effect of atmospheric refraction or earth obscuration on some of them, by comparison techniques which ensure that only those telescopes which have a satisfactory view or are functioning properly are utilized. After the satellite is initially placed in orbit, the attitude is approximately corrected by gyroscopic control before telescopic control is rendered effective.
