Abstract: 1520857 Checking store operation CSELTCENTRO STUDI E LABORATORI TELE COMUNICAZIONI SpA 14 Feb 1977 [13 Feb 1976] 06079/77 Heading G4A [Also in Division H4] Data apparatus DR operating to pass direct current data detected on lines C 11 -C mn  to processing unit DU comprises an m + 1 by n + 1 matrix of magnetic core stores, whose m + 1'th row, and n + 1'th column are used for checking the interrogation and reset, and readout, operations. Units CMA, CMB function in alternate cycles to control interrogation and reset of all the cores, row-by-row, both units CMA, CMB being operative for all cycles to detect the read-out data and pass it in serial form to unit DU. Checking.-Each unit CMA, CMB includes a checking circuit (CC), Figs. 2, 3 (not shown) which functions, during the reading of the m + 1'th row, to monitor the outputs, and resetting of the idle cores in that row, an alarm (AL<SP>1</SP>) being delivered in the event of malfunction. Provided that unit (CAS) has given no alarm, unit (CIR) is operative to ensure that the values read from each of the idle cores in the n + 1'th column are the same, otherwise an alarm (AL<SP>11</SP>) is delivered. Should either malfunction exist over a plurality of reading cycles a corresponding diagnostic signal on line (9) is added to the data to be passed to unit DU, a further added diagnostic signal comprising the parity, calculated in unit (GP) of the bits derived from the idle cores in the m + 1'th row. Read-out data handling.-The read-out data is amplified at (AS1-AS(n + 1) Fig. 2), the bits from each row together with the diagnostic bits being multiplexed into serial form in multiplex frames having a duration equal to a row read-out time. Interrogation and reset.-Fig. 5 (not shown). The rows are handled in p groups of q rows, means being disclosed to control the access of the cores in the groups to interrogation signals (IN) and reset signals (RS). The use of magnetic cores ensures high immunity against interference, as well as input-output decoupling. Unit AT may comprise documentation, checking, or charging units.

Title: Nuclear reactors
Inventor: MANN JOHN ERSKINE
IPC: G21C1/02
Filed: 1965-02-12
Abstract: 1,131,241. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 4 Feb., 1966 [12 Feb., 1965], No. 6265/65. Heading G6C. In a fast breeder reactor having a thermodynamically supercritical water coolant, material is added to the core structure to cause the coolant void reactivity coefficient to be negative. The moderating effect of the water coolant causes softening of the neutron energy spectrum, thus raising the non-fission neutron capture. Loss or voiding of coolant hardens the neutron spectrum, reduces the non-fission capture and thereby raises the core reactivity. To reduce this effect a material is added having a neutron capture property which is not a function of the neutron mean energy, thus maintaining a level of neutron absorption adequate to prevent an undesirable rise of reactivity upon loss of coolant. This effect is necessary in large reactors where neutron leakage due to coolant loss is small and is accompanied by only a small reactivity fall. The reactor core is cylindrical and is surrounded by an annular breeder region separated from the core by an annular zone containing coolant and zirconium metal, the latter having the required neutron capture property. The coolant volume fraction in the zone is greater than that in the core or breeder region. The coolant flow through the reactor is arranged to maintain a coolant density in the zone separating the breeder and fuel regions as a function of the power output of the fast fuel region and to effect neutron leakage control by reflection. The fuel and breeder elements are formed of vertical elongated casings supported on a horizontal grid by hollow spikes at their lower ends. Spaces are provided in the cases to receive fission product gases. The pressure vessel is double-walled with steel neutron shields between the walls which are watercooled. Light or heavy water or a mixture of the two may be used as the coolant. Natural uranium dioxide is the fertile material and uranium and plutonium dioxides the fast fuel. Power concentration at the core surface is reduced by a reduction of the fissile content at the core circumference.

Title: Pressure generating devices for vehicle braking systems
IPC: B60T8/26
Filed: 1973-02-08
Abstract: 1417023 Dual hydraulic braking systems GIRLING Ltd 30 Oct 1973 [17 Nov 1972 8 Feb 1973] 53322/72 and 6317/73 Heading F2F In a dual hydraulic braking system comprising a master cylinder 1 having pressure chambers 5, 4 for front and rear wheel brake circuits, and a pressure modulating or limiting valve 11 located in the rear wheel circuit means are provided to enable the valve 11 to be disabled or by-passed in the event of loss of pressure in the front wheel circuit. In the construction shown, forward movement of a piston 2 from chamber 4 pressurizes the rear wheel cylinders 10 via ports 17, 18 of a valve assembly 15 and valve 11 and causes corresponding movement of a piston 3 which pressurizes fluid in chamber 5 leading to the front wheel cylinders. If the front wheel circuit fails piston 3 engages a stem 23 of valve assembly 15 to unseat a ball valve 21 whereby pressure fluid from chamber 4 passes directly to the rear wheel cylinders via valve ports 17, 19. In a further embodiment the stem 23 is formed in two parts. Instead of being located at the end of the master cylinder housing 1 the valve assembly may be connected to the side thereof the ball valve member 21 being operated by a frusto-conical surface 24, Fig. 2 (not shown), provided on an annular flange of the piston 3. In another construction, Fig. 1 (not shown), a separate valve assembly is not provided, but forward movement of the piston 3 on the front wheel circuit uncovers a port (13) leading directly to the rear brakes so that piston 2 pressurizes the wheel cylinders through that port. Instead of valve member 21 being a ball it may have the form of a cylindrical part and a coned end for engaging the valve seat. The cylindrical part may be extended to provide a push rod to operate a warning device. Further, the valve 11 may be disabled directly by excess movement of the push rod which brings an abutment into a position in which it obstructs movement of a control valve piston.

Title: Improvements in and relating to the production of aluminium sulphate
Inventor: SAVAGE ROBERT LINCOLN
IPC: C01F7/74
Filed: 1963-02-16
Abstract: <FORM:1005052/C1/1> Aluminium sulphate is prepared by digesting a naturally-occurring aluminium ore with a ferric sulphate solution, which is obtained by treating a liquor containing ferrous ions and sulphate ions with a gas containing molecular oxygen, the digestion being conducted in an oxidizing atmosphere at a temperature from 100-350 DEG  C. and at a pressure from atmospheric to 5000 p.s.i.g. to form a solution containing aluminium sulphate, filtering said solution and treating the filtrate with a reducing gas, particularly SO2, and heat in the presence of concentrated sulphuric acid to precipitate any residual ferrous sulphate, filtering said ferrous sulphate from solution and crystallizing from the filtrate a substantially pure aluminium sulphate.  The aluminium ore may be mine waste or a clay and the solution of ferrous and sulphate ions may be waste pickle liquor, as in the preferred embodiment illustrated in which the oxidation of ferrous to ferric sulphate is performed either in the digester before the introduction of the aluminium source or in a separate oxidizer. An alternative operating sequence (not illustrated) is to introduce simultaneously the mine shale and ferrous sulphate into the digester and then to perform the oxidation of ferrous to ferric sulphate.  The mine waste may be predigested with waste pickle liquor to reduce its alkalinity before the main digestion. The effluent from the main digester is filtered, and reduced with SO2 in a solution of 35-50% sulphuric acid obtained as the filtrant from the initial evaporated waste pickle liquor; the reduced solution on filtration yields ferrous sulphate for recycle and aluminium sulphate solution for seeding.  Calcination of the aluminium sulphate crystals yields cell-grade alumina.

Abstract: 452,730. Television. COSSOR, Ltd., A. C., BEDFORD, L. H., and STEVENS, W. H., Highbury Grove, London. March 1, 1935, No. 6542. [Classes 40 (iii) and 40 (v)] To prevent burning of the fluorescent screen, the cathode-ray current is reduced when the scanning oscillations cease. The deflecting oscillations are applied to C1, Fig. 3, and are rectified by the diode stage of the diode-triode V to apply a prohibitive bias to the triode stage. When the deflecting oscillations cease, this bias is removed and the valve V effectively short-circuits the anode A1 and cathode F of the cathode-ray tube. According to the Provisional Specification, the cessation of the line scanning potentials is utilized to control the framing potential. A valve V5, Fig. 2, supplies charging current to the condenser C5. The line scanning potentials are applied to C1 and rectified by the diode V to supply a cut-off bias to valve V6. When the line deflecting oscillations cease, the valve V6 becomes conducting to discharge the condenser C5.
