Patent GB-909871-A (GB)
Title: Ferrite matrix storage device with individual core reading and spurious-pulse compensation
IPC: C12P29/00
Filed: 1959-11-16
Abstract: 909,871. Magnetic pulse-storage apparatus. STANDARD TELEPHONES & CABLES Ltd. Nov. 16, 1959 [Nov. 19, 1958], No. 38711/59. Class 40 (9). The Specification discloses several arrangements of cores and windings in a ferro-magnetic storage matrix whereby spurious voltages induced by core switching pulses in the common read-out winding are substantially suppressed. In general, the read-out winding through the cores is divided into two or four series sections, the spurious voltages induced in a pair of sections being mutually opposed. In the case of four series sections, the read-out voltage may be obtained directly at the ends of the read-out winding as a result of selective core switching by coincident row and column currents, or the winding may form a closed circuit with the read-out voltage obtained from two points in the circuit. The read-out winding may also serve as an inhibition winding, and in the schematic circuit shown in Fig. 15b read-out winding sections L-M and N-O are connected over transformers U4, U5 to inhibiting sources and over transformers U6, U7 to the read amplifier terminals A, B. It is stated that spurious signal reduction is also effected by arranging the reading winding to run parallel to the column or row conductors. One parallel conductor may have a thermo-plastic coating and is secured to a parallel conductor by heating. A matrix is described, Fig. 5, in which economy of access switches is obtained by having the row conductors Z and column conductors S common to two separate matrix planes the respective cores of which are displaced by 90 degrees. Coincident switching of a selected core is then determined not only by the selective energization of a column and row, but also by the polarity of the switching currents.

Abstract: 1,130,751. Vibratory mechanisms. SINEX ENG. CO. Ltd. 23 Dec., 1965 [23 Sept., 1964], No. 38820/64. Heading F2X. [Also in Division H2] A rotary vibrator, which may be used to maintain a flow of unset concrete through the neck of a feed hopper, is driven by a two or multi-speed A.C. induction motor, the speed of which may be altered by pole changing to produce vibrations of different frequency. The stator winding of a single speed motor may be modified so that three leads L 1 , L 2  and L 3  are joined to the terminal board to provide fourpole operation and to one another, with the coil centres connected to the terminal board, to provide two-pole operation. To provide the necessary six groups of coils, the stator may have 18 coils series connected in groups of three. Synchronous speeds of 2850 and 1425 r.p.m. are provided by two and four-pole operation and of 950 and 1425 r.p.m. by four and sixpole operation.

Filed: 1974-01-21
Abstract: 1454797 Mixing apparatus; centrifugal separators TEC GROUP Inc 21 Jan 1974 [22 Jan 1973] 39373/73 Headings B1C and B2P A homogeneous mixture of fluids (e.g. gas and liquid), solids, or a fluid and a solid is produced at a mixing and pumping station 100 and conveyed to a separating station 104 where it is centrifuged to at least partially separate the mixture into relatively high and low specific gravity portions which are led off through lines 114, 116. Separation at the station 104 is augmented and flow is stabilised by inclusion in the line, 102, between the stations 100, 104 of serially arranged transition and enlarged sections D-E and 108 so that relatively high gravity masses at high pressure and relatively low gravity masses at low pressure form at outer and central zones B, C respectively. The transition section may include an annular manifold. The pumping station 100 includes an axial flow pump 10 which may be single or multistage and comprises, in each stage, a cylindrical impeller rotor 12 having three integral inwardly directed impeller blades 14. The rotor 12 is journalled in a housing 18 and driven, e.g. from a motor not shown, through gearing 20, 22. A seal is formed between the rotor and the housing by mating of a ring 40, releasably secured on the rotor by pins 46 and a retaining ring, and rings 50, 52 secured to the housing. Additive is collected from a housing chamber 38 by a scoop-vaned ring 84 and directed through a peripheral groove 88 and ports 78 in the ring, valves 80 and outlets 64 in blunt downstream trailing edges 60 of preferably each of the blades, said blunt edges engendering low pressure regions and hence additive drawing suction behind the blades. Each valve comprises a ball 80 centrifugally released, in response to rotor speed, from a seat, in opposition to a force of a spring 82. The housing chamber 38 may be charged through a conduit 92. The separating station 104 also includes an axial flow pump the impeller blades of which are similar to the pump in station 100 but are of modified lead and pitch and do not include additive outlets. The station 104 pump has a lower pumping rate and provides for centrrifuging. The speeds of the pumps at 100, 104 are separately controllable.

A closed cycle gas turbine plant having an accumulator 18 which is charged with working gas bled off for the cycle and from which gas is fed back to the cycle, comprises an aerodynamic compressor connected in an auxiliary closed cycle with a fluid-operated machine, a controllable bleed for varying delivery of gas from the outlet of the main cycle compressor to the inlet of the aerodynamic compressor and a one-way bleed connection from the outlet of the aerodynamic compressor to the accumulator. The main cycle 10 comprises an axial flow compressor 11 delivering through a preheater 12 and a main heater 13, which may be a nuclear reactor, to a compressor-driving turbine 14 and a power turbine 15 in series, the exhaust returning to the compressor inlet through the preheater 12 and a water-cooled pre-cooler 17. The auxiliary closed cycle 21 comprises an axial flow or centrifugal aerodynamic compressor 22 which delivers by a conduit 25 to the fluid-operated machine, which is shown as a turbine 26 connected by a shaft to the aerodynamic compressor, the exhaust from the turbine returning to the compressor by way of a water-cooled precooler 28. The compressor 22 is also driven by a shaft connecting it to the compressor 11 by way of clutches and gear-boxes 33 and 34, an additional load 32 in the form of an auxiliary generator being interposed. The inlet of the compressor 22 is connected to the main cycle 10 by a conduit 29, the rate of flow of the gases from the cycle 10 being controlled by a valve 30. The delivery of compressor 22 is connected with the accumulator 18 by a conduit 38 which includes a non-return valve 39. The accumulator 18 is connected with the inlet of the compressor 11 by a conduit 19 which includes a valve 20. The valves 20 and 30 are operated in opposition, one opening as the other closes, to vary the power output of the plant. In one modification of this drive, this generator is dispensed with, in another (Fig. 3, not shown) the additional drive to the compressor 22 is obtained from an electric motor. In a further modification, no additional drive is provided, a heater being then provided in the conduit 25 between the outlet of the compressor 22 and the turbine 26. The working fluid of the cycles may be helium.

A gas generating unit comprises a water chamber (4), a chamber (5) for a component generating gas with water and a passage (7) controlled by a valve (14) operated by the pressure of the generated gas, which permits flow of water vapour to the chamber for said component. As shown in the Figure, to which the numerals refer, a flat circular metal box I has a stressed rubber diaphragm 8 providing the lower boundary of the water chamber, a partition 2 supports calcium hydride, a perforated partition 3 defines with the upper surface a chamber 6 containing glass wool, and the ball valve is operated by rod 15 connected to the diaphragm; a baffle 12 is provided below the offtake tube 11.
