Title: Memory arrangement for a computer
IPC: G11C7/00
Filed: 1973-06-06
Abstract: 1386227 Faulty memory location replacement TELEFONAKTIEBOLAGET L M ERICSSON 6 June 1973 [9 June 1972] 27088/73 Heading G4A Each word location of a memory OM has at least one replacement bit location Er, and input output switches for each bit location 1-n of a word determine whether a write or read operation is performed on the location Er associated with the word location selected by a word address register OAR. If more than one replacement location Er is provided for each word, a set of n input output switches is provided for each set of replacement locations. When an address is supplied to OAR to address a word in memory OM, a memory BM is also addressed to supply a bit index specifying one of bits b1-bn. When reading a word known to contain a faulty bit, an indicator bit RS enables the output gate G31-G3n, via a gate G41-G4n, for the faulty bit specified by bit index decoder BA to supply the bit read from the location Er of the addressed word over ULr to the appropriate bit position in word-register OR. When writing into a word having a faulty bit location, the decoder BA enables the corresponding bit gate G11-G1n to write the bit concerned on IL1-ILn into the location Er of the addressed word. Monitoring memory operation.-With the indicator bit RS set at O, the output gate G6 of an exclusive OR comparator OV is enabled whereby the contents of a bit location E1-En specified by BR and the contents of the replacement location Er for an addressed word are compared during a read operation to provide an alarm signal if the contents do not correspond, the location Er having been loaded previously with the same bit signal as the bit location E1-En specified by BR. Generation of the alarm signal may be used to enter the bit index in BR into the memory BM at the current address in BAR. The contents of BR and BAR can also be used as check data in a fault tracing program. The bit index addresses of memory BM may be permanently associated with word addresses of memory OM or a flexible association may be chosen using a relatively small memory BM.

Title: Improved means for regulating internal combustion turbine plants
Filed: 1945-10-17
Abstract: 602,554. Gas turbine plant. AKT.-GES. BROWN, BOVERI, & CIE. Oct. 17, 1945, No. 27165. Convention date, Nov. 10, 1944. [Classes 110 (i) and 110 (iii)] In a gas turbine plant comprising at least two compressor-turbine sets on separate shafts, the compressors and turbines being in series and one compressor-turbine set providing useful power, the fuel supply to the combustion chamber preceding the turbine providing useful power is regulated directly from the power regulator and the fuel supply to the other combustion chamber or chambers is regulated directly or indirectly from the same regulator. In the plant shown in Fig. 3, the high-pressure set 3, 5 drives a useful power generator 8 and the fuel supply to the combustion chamber 4 is regulated directly from the governor 10. The fuel supply to the combustion chamber 6 is regulated by the governor 11 on the lowpressure set but the setting of that governor is regulated by the governor 10. The servomotor 13 operating the fuel supply means to chamber 4 has an over-riding limit control from a thermostat 15. A limit control on the low-pressure set is provided by a thermostat 14 which controls a byepass 16 across the lowpressure set. In another plant, the lowpressure set provides the useful power and its governor controls the separate fuel supplies to the combustion chambers before both high and low pressure turbines. The governor on the high-pressure set has a limit control over the fuel supply to the high-pressure combustion chamber and there is a device in the control pressure fluid line to prevent this latter governor affecting the servomotor controlling the fuel supply to the low pressure combustion chamber. In a variation of this plant, the direct control of the fuel supply to the high pressure combustion chamber by the speed governor of the low-pressure, useful power set is omitted and that fuel supply is controlled only by a speed governor on the high-pressure set. Alternatives to the limit control 14, 16, Fig. 3, are described. In one, power is transferred from the high-pressure to the low-pressure set shaft by means of a motor in place of the starting motor 9 which is regulated from the thermostat 14. In another, the low-pressure turbine 7 is provided with a ring of initial guide blades the angular position of which is controlled from the thermostat 14. These blades are radial flow blades in front of the normal axial inlet to the axial flow blading. In a third, a stand-by high-pressure stage is provided in the turbine 7 which can be put in parallel with the normal high-pressure portion of that turbine by means of the thermostat 14. In a fourth, the highpressure compressor 3 has an initial ring of angularly-adjustable guide blades, the positions of which are controlled by the thermostat 14.

Title: Production of aqueous uranyl sulphate solution from uranium dross
IPC: C01G43/00
Filed: 1945-10-20
Abstract: Uranyl sulphate solutions are obtained from uranium dross arising from the working of metallic uranium and from the slags obtained in the recovery of metallic uranium by reduction of uranium tetrafluoride with calcium or magnesium and separating the metallic uranium, by burning the dross (or slag) in air, preferably at 600 DEG to 1000 DEG  C., and thereafter mixing the oxidized dross with lime and roasting in contact with air at 600 DEG  1000 DEG  C. If chlorides are present in the dross they may be eliminated by adding a small amount of iron oxide or ammonium sulphate during either of the air calcining steps.  The quantity of lime employed is that theoretically necessary to form calcium diuranate although an excess of either lime or uranium may be present.  The roasted product is then mixed with sulphuric acid solution and treated with an oxidizing agent to convert any tetravalent uranium into hexavalent form.  The preferred sulphuric acid concentration is 5 to 50%.  The oxidation of the sulphate solution may be effected with air, hydrogen peroxide, permanganate, chromate or nitrate, the preferred reagents being air initially and hydrogen peroxide to complete the oxidation.  The calcium sulphate formed precipitates and may be separated by filtration, the solution preferably being adjusted to a pH of 2 to 4 before effecting the separation.  Iron precipitates with the calcium. According to an example, a metallic uranium product obtained as scrap from metal workings and as dross from metal melting and pour operations is converted to U3O8 by heating in air at 600 DEG  to 1000 DEG  C. and the roasted product is mixed with lime and heated in a rotary kiln to 700 DEG  to 800 DEG  C. in the presence of air for 3 hours. The calcium diuranate product was then crushed and dissolved in 15 1/2 % strength sulphuric acid at 85 DEG  to 90 DEG  C. and agitated for 2 hours at 90 DEG  to 95 DEG  C.  Aqueous 27 1/2 % hydrogen peroxide solution was then added and the charge agitated at 90 DEG  to 95 DEG  C., whereby the pH dropped to 0.5 to 0.6.  Calcium carbonate was then added to adjust the pH to 3.7 and the mixture held at 90 DEG  to 95 DEG  C. whereby the iron and calcium precipitated leaving a purified uranyl sulphate solution.  The reference is made to the recovery of uranium as uranium peroxide from this solution by the process of Specification 829,088.

Title: Improvements in engine starters
IPC: F02N99/00
Filed: 1925-11-09
Abstract: 265,306. Rogers, F. H., (Eclipse Machine Co.). Nov. 9, 1925. Turning-gear.-In a starter comprising an inertia device such as a flywheel set in rotation by suitable operating means and afterwards connected to the engine to be started, a one-way driving-connection between the operating means and the inertia device is disconnected when the inertia device is rotated by other operating means. In one form, Fig. 2, the fly-wheel 60 is set in rotation by an electric motor 70 acting through a ball or roller ratchet clutch 68. The flywheel 60 is connected to a clutch member 14, movable into engagement with a clutch 15 on the engine shaft 16, by transmission mechanism comprising bevel gears 45, toothed gearing 43, 41, 39, and planet wheels 31 meshing with a fixed internally toothed gear 29. A carrier 33 for the planet wheels is splined to a barrel 4, between which and a shell 5 is a multiplate clutch 6 acted upon by adjustable springs 7. Internal threads 12 in the shell 5 engage a screwshaft 13 connected by splines to the clutch member 14, which is held by a spring 22 against the head of a rod 23 passing centrally through the gearing and provided with a handle 25. A flange 26 on the rod 23 abuts against the rear end of the shaft 13, and the rod serves to move the clutch member 14 into engagement with the member 15 when the fly-wheel has been set in rotation. When the engine starts, the screwed connection 12, 13 disengages the clutch. If the engine fails to start, the member 14 may be disengaged by axial movement of the rod 23 before effecting a fresh operation of the starter. F'or starting by hand, a bevel gear 49 on a central supporting shaft 24 is driven through a bevel gear 57 on a shaft 52 actuated by a starting-handle. The shaft 24 carries pins 38 in engagement with the planet-wheel carrier 33, so that the rotation of the shafts 52, 24 is transmitted through the planetary and toothed gearing to the fly-wheel but not, in view of the one-way clutch 68, to the motor 70. In a modification, the clutch 68 is replaced by a one-way driving connection consisting of a cup-like member in screw-threaded connection with the armature shaft of the motor and moving automatically into frictional engagement with the web 61 of the fly-wheel when the motor is in rotation. In a further form, Fig. 16, the armature shaft is screw-threaded between shoulders 76, 77 and engaged by a nut 79 on which is splined a sleeve 81 having clutch jaws 82 for positive engagement with a clutch member 84 splined to the shaft 63 of the fly-wheel. A spring 85 is interposed between the sleeve 81 and a flange 86 on the nut 79, and a second spring 87 holds the nut 79 normally against the collar 76.

Abstract: 1,037,160. Semi-conductor devices. MOTOROLA Inc. July 2, 1965 [Aug. 24, 1964], No. 28202/65. Heading H1K. A semi-conductor voltage divider comprises a reverse biased input junction the depletion layer of which extends to a plurality of output junctions each of which floats at a voltage dependent on its distance from the input junction. As shown, Fig. 3, the input junction 28 is provided between P-type region 29 and N-type region 30 either by diffusing boron into an N-type wafer or by epitaxially growing the N-type layer on a P-type substrate. The output junctions are produced by diffusing boron through apertures in an oxide mask 40 to form P-type regions 35, 34, 33 which extend to different depths. An ohmic contact 32 is applied to N-type region 30, aluminium contacts 24, 25, 26 are applied to P-type regions 33, 34, 35 and P-type region 29 is provided with a gold layer 31 by means of which the wafer is mounted on a header 13 to which is bonded a cover 11, Fig. 1 (not shown). N-type region 30 is of higher resistivity than P-type region 29 so that when a voltage is applied between terminals 15 and 16 to reverse bias input junction 28 the depletion layer extends towards the output junctions. Each of regions 24, 25, 26 float at a voltage equal to the input voltage at which the depletion layer just reaches it. When an external load is connected between an output region and contact 16 the output junction becomes forward biased and conducts heavily thereby producing a regulated voltage equal to the difference between the input voltage and its floating voltage. In an alternative embodiment, Fig. 4 (not shown), the bulk of the wafer is of N-type conductivity, the input junction being formed by a P-type region 44 provided in the centre of the upper face. The output junctions are formed by P-type regions 41, 42, 43 surrounding the input junction and extending to equal depths into the wafer. In this embodiment the depletion layer extends laterally from the input junction to the output junctions thereby causing them to float at different voltages. The device is suitable for inclusion in integrated circuits especially since the only current drawn under no-load conditions is the leakage current of the input junction. Complementary devices may also be produced.
