Title: Improvements in or relating to information stores
IPC: G11C15/02
Filed: 1964-01-29
Abstract: 1,057,831. Associative memories. NIPPON ELECTRIC CO. Ltd. Jan. 29, 1964 [Jan. 29, 1963], No. 3722/64. Heading G4C. A content-addressed memory is interrogated in groups of words, a positive response from any word of a group being recorded, so that the time taken to interrogate the whole memory is less than that required for a word-by-word comparison. As shown, sixteen words, each of three bits stored in magnetic cores, are interrogated by first energizing the lines 6 linking the cores of the first group of four words, I11, I12 and I13 being successively operated so that the outputs on lines 7 represent the serial comparison results for the first four words. These outputs, which are arranged to be zero for each identity bit relationship, are applied to four bi-stable circuits so that any unswitched circuit will indicate identity, and an OR circuit detects if any identity in this first group of four interrogated words has been found. The four circuits are then reset and the next group of four words interrogated by I21-I23, and so on.

Filed: 1947-02-07
Abstract: 631,257. Gate-operating appliances. HASLAM, O. H. Feb. 7, 1947, No. 3728. [Class 65(i)] [Also in Group I] A gate of the kind which is displaceably carried by a tiltable runway and which moves substantially in its own plane, the runway being tilted by means operated by a depressible platform situated in the approaches to the gate, is characterised in that the runway with its supports is disposed, at least in the open position of the gate, wholly at the side of the gateway. As shown, a pair of oppositely moving gates 28 are each provided with an extension frame 29 and are each suspended by means of rollers 30, 31 from a runway 25 pivotally mounted at 26 on a post 27. The platform 1 is adapted, when depressed, to displace the upper arm 16 of a double armed lever, the lower arm 17 of which is connected by cables 20, 21 to the inner ends of the runways. The latter are thus raised when the platform is depressed and cause the gates to open, the gates closing under their own weight when the platform is released. Check means may comprise a pair of members frictionally engaging the runway and connected rigidly together, one or other of said members being struck by the rollers towards the ends of the travel of the gate. In a modification the runway is itself slidably mounted on the upper arm of a T-shaped lever, the lower arm being connected by a rigid linkwork to the means operated by the depressible platform. In this arrangement the gate is closed by means of a counterweight incorporated in said operated means. In a further modification the slidable runway is rigidly connected to the gate.

Title: Voltage stabilising circuit
IPC: H04N3/185
Filed: 1968-01-25
Abstract: 1,207,262. E.H.T. supplies. INTERNATIONAL STANDARD ELECTRIC CORP. 25 Jan., 1968 [2 Feb., 1967], No. 3895/68. Heading H2F. In an E.H.T. stabilizing circuit, for a cathoderay tube, of the type including rectification of the output of a controllable pulse-operated power stage, the control voltage is derived by combining with opposite polarity a first voltage produced by rectification of the rear portion of pulses derived from the power stage and a second voltage derived by rectification of the front portion of said pulses. As shown, the pulseoperated power stage 27 is coupled by means not shown, to a transformer, the output of which is rectified at 31 to produce the E.H.T. voltage. A negative pulse between terminals 1 and 2 of the transformer is differentiated at 28, the positive portion of which (corresponding to the rear edge of the pulse) is rectified at 4 and combined with the output of a rectifier 8, operative on the front portion of the pulse. The combined control voltage (adjustable at 12) is superimposed on a ripple voltage (derived from a capacitive divider 15, 32) and passed via a transistor 16 and rectifier 20 to the grid of the power tube 27 where it is further combined with the drive waveform supplied via capacitor 25 and flyback pulses supplied via capacitor 22. The voltage derived from the rear portion of the pulses acts to stabilize the E.H.T. voltage against supply variations whilst that derived from the front portion of the pulses compensates for the internal impedance of the E.H.T. circuit.

Title: Wind driven power plants
IPC: F03D13/20
Filed: 1976-02-03
Abstract: 1511948 Wind motors A KLING 3 Feb 1976 [14 Feb1975] 04089/76 Heading FIT A wind motor having a rotor assembly mounted in support structure for rotation about a horizontal axis includes wind alignment adjusting means for moving the rotor assembly about vertical and tilt axes whilst permitting the assembly to gyroscopically precess. In one arrangement, Fig. 1, the wind motor comprises two coplanar rotors 1, 2 counterrotating about axis 3 and carried by support structure 4. The latter is mounted in bearings 5, 6 enabling tilt adjustment by electric motor 12. Bearings 5, 6 are themselves carried by a framework 7 attached to base-plate 7' having rollers 8 running on ring 9 for adjustment of the framework about a vertical axis under control of electric motor 11  driving one of the rollers 8. Rotor axis 3 is maintained in alignment with the wind direction by a gimbal-suspended measuring vane which transmits signals to a controller. The latter also receives signals indicative of the speed of the rotors and transmits resultant electrical signals to motors 11, 12 causing appropriate angular adjustment of rotor axis 3. Inner rotor 2 carries at its outer periphery 2' permanent magnets which co-operate with wound electromagnets on outer rotor 1 to form an electric motor/generator connected via leads extending along structure 4 to a mains network. An additional motor/generator may also be formed at the inner periphery of inner rotor 2. The latter may be supported by spokes 20, Fig. 5, from central hub 17, outer rotor being similarly supported by spokes 19, 19' from hubs 18, 18'. In a modification, Fig. 3, the hubs are replaced by a fixed annular support ring 33 disposed between the rotors 1, 2 and carrying them via roller bearing tracks 37. Motor/generator magnets 21, 25 are provided. The upstream edge of support ring 33 carries four circumferentially spaced flaps 38 pivotal into the air-flow entering rotor 1 by motors 39 of solenoid or piston and cylinder type. Flaps 38 can be operated simultaneously to restrict the air-flow, or individually to cause a torque about the tilt axis of the rotors, which torque assists or replaces that provided by motor 12. In a further modification, the tilt axis bearings 5, 6 of Fig. 1 are replaced by lead screw drives 39, Fig. 5 co-operating with guides 16', 16" at opposite ends of the rotor shaft so as to enable tilting of the latter. In another arrangement Fig. 4 (not shown) no vertical support structure such as 7 is provided but the rotor assembly is supported by structures (14, 15) from the sides of a canyon. Adjustment of the rotors about a vertical axis is effected by guides and lead screw drives similar to the means for tilt adjustment in Fig. 5. The rotors may drive pumps instead of motor/ generators and need not counter rotate, the gyroscopic effects being additive instead of tending to compensate. Figs. 6 to 8 (not shown) illustrate further details of the motor/generators.

Abstract: 879,569. Television pick-up tubes. ELECTRIC & MUSICAL INDUSTRIES Ltd. Jan. 27, 1958 [Feb. 7, 1957], No. 4225/57. Class 39(1). An electron discharge device comprises a target which includes a spongy layer of B.I.C. material, means for bombarding this layer with high velocity electrons whereby the layer acquires charges dependent on the intensity of the incident electrons, and means to project low velocity electrons on to the layer to neutralise these charges. In one embodiment a television pick-up tube has a target comprising a conducting grid 2 on which is disposed a continuous conducting sheet 3 which supports a spongy layer 4 of red antimony trisulphide 2-3Á thick. This layer may be formed by evaporation in a gaseous atmosphere at low pressure, for example in xenon at 0.3 mm. Hg. At one end of the envelope 1 is a photoelectric cathode 5 in contact with a transparent electrode 6. Photoelectrons are accelerated towards the target by electrode 7, focused by coil 8 and pass through grid 2 and sheet 3 on to layer 4 producing areas whose conductivity corresponding to the original optical image. Sheet 3 is maintained at a positive potential with respect to the cathode so that positive charges appear on the surface of layer 4 facing the electron gun 9, 10, 11. The beam from this gun is accelerated by anode 12, decelerated by electrode 13 and scans layer 4 by means of scanning coils 14. The scanning takes place in the presence of a longitudinal magnetic field from coil 15 so that the beam always impinges on the target at right angles. The low velocity scanning beam thus discharges layer 4 and produces picture signals across resistance 16. The target may include one or more layers of solid B.I.C. material about 0.1Á thick in addition to the spongy layer, and need not be of the same substance. Other suitable materials are arsenic trisulphide, silicon monoxide, silicon dioxide, magnesium fluoride, calcium fluoride and zinc sulphide. Specification 668,727 is referred to.

Abstract: 111,413. Thomas, W., and Mainwaring, A. E. March 29, 1917. Gas-producer furnaces.-A combined coking, gasifying, and primary-combustion chamber is constructed with a lower part of greater width for the body of coked and ignited fuel and an upper part of less width for gasifying fresh fuel, the gas being exhausted from the upper part so that poorer hot gases are drawn from the body of incandescent coke through the fresh fuel. The gas is delivered to a combustion chamber to which air is supplied, and some of it is delivered also to the fuel chamber. In a modification the whole of the gas is delivered into the fuel chamber on its way to the combustion chamber. In the form of furnace shown in Figs. 3, 5, and 6, fuel is supplied to the narrow upper coking section 2<a> from a hopper 9 by a screw or other feeder 10 driven through friction gearing which allows the feed to stop when the coking chamber is full. After coking, the fuel descends by gravity to the wider portion 2 and is burnt on a grate formed of inclined sections 4, the bars of which are rocked by eccentrics. Clinkers &c. are removed by a revolving breaker 4a. The gases evolved in the coking section are withdrawn by a fan 31, mixed with air supplied through a valve b, and returned, some to the fuel chamber through ports 41, and the remainder to the secondary combustion chamber 15 through a series of flues 38 in the side walls of the furnace. Air for combustion of the gas is forced by a fan 18 through a heater in the smoke stack of the boiler 16, and delivered in part through flues 26 opening into the gas flues 38, and the remainder through ports 29 in the dividing wall between the fuel and secondary combustion chambers. The air-heater consists of sinuous pipes 21 arranged in parallel between upper and lower headers. The products of combustion from the lower part of the furnace enter the secondarycombustion chamber through ports 14, 14a. In another form of furnace shown in Figs. 8 and 9, the gases evolved in the coking section, 52a are withdrawn through a port 57 and returned to the lower part of the furnace through flues 58 by jets of superheated steam.

Filed: 1951-02-26
Abstract: <PICT:0680604/III/1> In the regeneration of finely-divided non-combustible solids, e.g., catalysts, decolorizing clays and filter aids, which have become contaminated by their use in the treatment of oils or other liquids or vapours by first removing more easily removable carbonaceous deposits with a stripping gas, e.g. steam and then removing the remaining carbonaceous deposits by burning in a combustion supporting gas, e.g. air, both operations being effected with the fluidized technique, the stripping and burning operations are carried out in separate but contiguous zones which are in indirect heat-exchange relationship and a portion of the solid is continuously cycled from the burning zone to a bed of solids positioned above the stripping zone and from there to the stripping zone, the bed of solids forming a seal between the burning and stripping zones.  As shown, the vertical vessel 1 is divided into stripping and burning zones by a partition 2.  A fluidized bed of solid is maintained in each zone, contaminated solid and steam being fed to the stripping zone at 5 and 17 respectively and air being fed to the burning zone at 15. Stripped solid flows from the stripping zone to the burning zone through a gap at the lower end of partition 2.  To effect continuous transfer of solid from the burning zone to the stripping zone a trough 3 forming a top closure to the stripping zone is fed with solid from the burning zone by a lift pipe 10, the solid in the trough gravitating into the stripping zone through downpipe 4.  The regenerated solid is withdrawn at 14 and flue gases are withdrawn at 6 and 13.
