Patent GB-1380983-A (GB)
Title: Data processing systems
IPC: G06F11/16
Filed: 1972-05-08
Abstract: 1380983 Data processing system SIEMENS AG 8 May 1972 [12 May 1971 30 June 1971] 21307/72 Heading G4A A data processing system includes a data processor through which operands are passed in parallel by bit for processing, the processor being divided into two sections and arranged such that operands or parts thereof are fed in parallel by bit through both sections where they are subjected to identical processing and such that the processing results from the two sections are compared in order to indicate the presence of a fault. As described the processor is a 32-bit parallel device. Operands may be half width, 16 bits, or full width, 32 bits. Several modes of operation are described. In the first, with half width operands, the operands are fed through both sections of the processor, the processed results being compared to indicate the presence of faults. In the second, with full width operands, the operands are divided into more and less significant portions which are stored in separate sections of the store As. The less significant portions of two operands A and B, AL and BL, are fed in parallel through the two sections of the processor which comprise registers RS1 and RS2, processing units VE1 and VE2, and output registers ZSP1, ZSP2, a comparator VG serving to compare the processed results. The results are then stored in the store As and a similar procedure adopted for the more significant portions AH and BH. The processing unit has a carry input U which adds carries resulting from the processing of the less significant portion into the more significant portions. If the comparator indicates that no faults have occurred a full width operand is fed through the processing unit, now acting as a single section. In a further mode the test may be completed using only the less significant portion of the operands after which a full width operand is processed. In a further mode of operation in which a full width operand is processed in two halves, the results of processing the two halves are accumulated in the store As so that the test cycle also serves as the processing cycle. All modes of operation may involve several comparators, e.g. placed before and after each unit so that the precise location of the fault may be determined. Storage of the results may be overlapped with the supply of the next operands or operand parts to save time. The Specification states that the processor may be divided into other than only two sections with the appropriate comparators.

Patent GB-646901-A (GB)
Title: Improvements relating to circuit arrangements for the control of a direct current relay
IPC: H01H51/34
Filed: 1948-08-13
Abstract: 646,901. Automatic control systems. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., STEVENS, S. A., and DUCKITT, H. Aug. 13, 1948, Nos. 21405/48 and 5821/49. [Class 38 (iv)] In a automatic voltage or current control system, the energy stored in the electromagnetic field of a relay is used to open the contacts of the measuring relay, the amount of opening varying inversely with the magnitude of the deviation measured. The voltage of the load L fed by a rectifier 26 from a 3- phase supply through a voltage regulator 24, is controlled by connecting the coil 2 of a polar relay across the load in series with an opposing reference voltage 40. Load voltage deviations cause contact 3 to close on to, e.g. contact 12, 2 (from rectifier 14 through resistors 21, 22) and short-circuiting control relay B. Control relays A and B are connected in series across the auxiliary D.C. supply from rectifier 14 and arranged so that neither is sufficiently energized to operate until one or the other is shortcircuited. Operation of relay A closes contact A2, operating an intermediate relay 32 controlling the field of a reversible motor 29 driving the voltage regulator 24. Simultaneously, the contact A1 is closed to energize a time-delay relay C which, after the delay (during which the voltage regulator is operating) opens the contact C1 to open the circuit supply to the control relay A. The transient induced current in the coil of this relay discharges through the polar relay 2, opposing the normal energization due to the load voltage. The contact 3 therefore opens, the distance moved depending upon the magnitude of the load voltage error, i.e. for small deviations the contacts open further than for large deviations when the relay is strongly energized. Opening the polar relay opens the control relay A, de-energizing the regulator controls and de-energizing the time-delay relay C so that the contacts C1 again close and the cycle is repeated, the polar relay reclosing the more rapidly the greater the load voltage error to be corrected. The intermediate relay 32 has slow release characteristics so that if the polar relay 2 recloses very rapidly, the relay 32 will still remain closed to effect continuous operation of the voltage regulator. In a modification, Fig. 2 (not shown), the relay 32 is omitted, the regulator being controlled directly by the control relays A, B, and the time delay relay C is normally energized, being de-energized by the control relay to effect the delayed opening of the control relay circuit. In a further modification, Fig. 1 (not shown), the polar relay has one pair of contacts only operating on the upper limit, and a single control relay operates the regulator,

Title: Vertical take-off and landing aircraft
IPC: B64C29/00
Filed: 1961-06-19
Abstract: 915,347. Jet-propelled vertical take-off aircraft. LESLIE, T. June 19, 1961, No. 21986/61. Addition to 909,466. Class 4. A vertical take-off aircraft comprises a vertically mounted jet propulsion engine 2 an outwardly flared annular duct 12 ducting the jet radially to a system of annular aerofoils 13, 14 and 15 surrounding the jet and co-operating with it to produce lift, engine 2, duet 12 and aerofoils 13, 14 and 15 being contained in a well 5 which is flared at the top and an annular nozzle 21 through which the flow from the annular aerofoils is exhausted in a downward direction to produce an upward thrust on the aircraft. Engine 2 is braced to the walls of well 5 by members (not shown) which may serve as fuel tanks. The annular aerofoils are supported by members 16 to 19, and a sleeve 20, shrouding duct 12, is designed to induce a flow of air parallel to the jet at the point of emission from duct 12. For control purposes, the flow in annular nozzle 21 is tapped at grids 22, 23 and led by ducts 24, 25 to control fins 26, 27. Movement of these fins away from or towards the orifices of the ducts varies the flow in the ducts, and the flow in nozzle 21 and hence the upward thrust due thereto is correspondingly varied. Also the efflux from ducts 24, 25 passing over the control fins produces lift which depends on the spatial relationship of the duct orifices and the fins. Forward propulsion is provided by two jet propulsion engines (not shown) located at the rear of the aircraft.

Title: Improvements in or relating to the isomerisation of alkanes and catalysts therefor
IPC: B01J27/045
Filed: 1957-07-11
Abstract: Catalysts for the isomerization of alkanes comprise sulphided rhodium supported on a base consisting mainly of alumina, such catalysts may be prepared by contacting a calcined composition of rhodium on said base with a sulphiding agent at 70-1000 DEG  F. and a pressure of up to 100 p.s.i.g., or by precipitating rhodium with hydrogen sulphide in the presence of an alumina hydrate followed by calcination in nitrogen.  The catalysts may contain 0.01 to 2% rhodium.  The base may contain up to 8% of an acidic promoter such as chlorine or fluorine and up to 35% of a silica, magnesia or boria.  Suitable sulphiding agents are hydrogen sulphide, carbon disulphide, C1-C5 alkyl mercaptans, dialkyl sulphides or disulphides containing 1-5 carbon atoms in each alkyl group or a sulphur-containing naphtha. Preferably the sulphided catalyst should contain 0.01 to 1% of sulphur.  In an example, to a slurry of alumina hydrate are added solutions of rhodium chloride and ammonium fluoride and the resulting slurry is dried at 120 DEG  C. and calcined at 900-930 DEG  F. in air for 3 hours to give a composition containing 0.44% rhodium and 0.69% fluorine.  This was treated with hydrogen sulphide at 475-510 DEG  F. and 200 p.s.i.g., and used to isomerize n-pentane.  Specification 735,390 is referred to.ALSO:Alkanes containing 4 to 12 carbon atoms are isomerized to more highly branched alkanes by passing with 1 to 20 mols. of hydrogen per mol. at 650-1000 DEG  F., 200-1000 p.s.i.g. and a weight hourly space velocity of 0.5 to 20 over a sulphided rhodium catalyst supported on a base consisting mainly of alumina. The catalyst (see Group III) may contain 0.1 to 2 per cent rhodium and 0.01 to 1 per cent of sulphur and the base may contain up to 8 per cent of chlorine or fluorine and up to 35 per cent of silica, magnesia or boria.  The process is particularly suitable for isomerizing C4-C6 normal alkanes.  The feed may be a mixture of alkanes and may also contain other materials but should contain at least 50 mol. per cent of alkanes, preferably normal alkanes. Similarly the hydrogen may be a hydrogen-containing gas as found in a refinery also containing gaseous hydrocarbons.  Fixed moving or fluidized beds can be used in bath or continuous operations. The branched chain products may be separated from normal alkanes by fractionation or selective adsorption using crystalline sodium and calcium aluminosilicates, and unchanged material may be recycled.  In an example the catalyst contains 0.44% rhodium and 0.69% fluorine on alumina and is sulphided with hydrogen sulphide; this is used in the isomerization of n-pentane at a W.H.S.V. of 5 and a molar ratio of hydrogen to pentane of 5 at 830 DEG  F. and 300 p.s.i.g.; 55% of the n-pentane is converted to isopentane in a yield of 94.5%. Specification 735,390, [Group III], is referred to.

Abstract: 1,192,612. Electro-encephalogram apparatus. J.F. TÍNNIES. May 12, 1967 [May 13, 1966], No.22081/67. Heading G1N. A voltage wave, curve a, obtained from electrodes attached to a patients skull is analysed, curves b and c, to obtain the time intervals of successive cycles and these are then translated by means of a linear ramp-voltage generator, curve d, into voltages the amplitudes of which represent the cycle times. The voltages control the deflection of a recording or display device which is arranged to produce an indication only when in its final deflected portion. A record or display is thus built up as a pattern of dots as shown in curves f and g, where each dot indicates one cycle of the wave, successive dots being displaced in the horizontal direction in accordance with their times of occurrence and in the vertical direction in accordance with the times of the cycles they represent. As illustrated, the cycle times are determined from the times at which the wave makes successive crossings of the zero axis in a given direction. Trigger pulses are produced at these times and are employed to control the rampvoltage generator. As an alternative, the times may be determined from the passage through successive peaks. In general, the cycle time may be determined from consecutive attainment of corresponding values of voltage in a complete cycle. The voltages representing the cycle times are entered into and read out from two stores which are brought into use alternately under control of the trigger pulses. By the use of a servosystem with a feedback loop, the record or display device may be released to make an indication, when in its finally deflected position, by detecting when the current in the servosystem falls to a minimum. Alternatively, the release may be effected by the trigger pulse at the commencement of the next cycle. Reference is made (without giving details) to the use of electric current and heat responsive paper recorders, ink recorders, light beam recorders and cathode-ray tube systems. Reference is also made to arrangements for controlling the size of the reproduced spots in accordance with the amplitude of the waves during the corresponding cycles. Apparatus for carrying out the invention is described, in block diagram form only, with reference to Fig. 1 (not shown).

[Also in Division H2] A continuously-movable metal tube is heated by the Joule effect by supplying it with threephase A.C. through pairs of rollers spaced along its length, Fig. 1 (not shown). In the embodiment shown in Fig. 3, the tube 1 runs between electrically conducting rollers 5a, 6a whose rotatable shafts 7a, 7<SP>1</SP>a have extensions 12a, 16a immersed in a mercury bath 14a to pass current from a conductor 17 to the tube 1. Support frames 8, 9 are slidably adjustable, and the mercury-resistant tank 14a has an appropriately-shaped dust-proof cover 20. If desired, only one roller may be conductive, with a smaller modified mercury bath for its extension, Fig. 2 (not shown). These embodiments may be modified by replacing the shaft extension(s) by electrically-conducting members secured to the roller(s) and dipping in the mercury bath, the roller shaft thus not carrying current. An embodiment using this modification is shown in Fig. 4 in which conducting rollers 5b, 6b have projections 18 formed as cylinders or spaced vertical blades which dip into the mercury bath 14b, the shafts 7b, 7<SP>1</SP>b thus being of insulating material if desired. These shafts may be stationary, Fig. 5 (not shown). Additional heating current for the tube may be supplied by one or more conducting shoes located " downstream " of the rollers, Fig. 1 (not shown) and each comprising a member 21 carried by a pivoted arm 22 and having a concave surface maintained in contact with the tube 1 by a jack 24 pivoted about the arm 22, Fig. 6 (not shown).
