Abstract: 1,091,893. Programmed control of temperature; fluid-pressure servomotor systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. and JOHN BROWN LAND BOILERS Ltd. Jan. 26, 1965 [Jan.28, 1964], No.3618/64. Headings G3N and G3P. In a vapour generating installation, comprising a plurality of independent groups of fuel burners, the rate of supply of fuel to the burners in use is controlled by a system responsive to a firing rate control signal which is selected as the lesser of a vapour pressure signal and a heat exchanger metal temperature signal, when the control signal is greater than a first preset value the number of burner groups is progressively increased and when lower than a second preset value the number of groups is progressively reduced. As shown, a radiant type steam boiler 1 having a vertically elongated furnace 3 is fired by four horizontal rows of burners 5A-5D and hot gases leave the furnace by a lateral pass 7 over a primary superheater 9 and a secondary superheater 11. Each burner row is supplied with air entrained fuel from a coal pulverizing mill 15A- 15D fed by a feeder 25A-25D. Associated with the fuel burners are oil fired pilot burners to which fuel is supplied through a valve 27. The pressure in a steam main is sensed by a transducer 31 and fed to a controller 33, having the set point varied from a controller 35, providing a pressure error signal, having proportional, integral and differential terms, to a signal detector 45 having a second error signal input, having proportional, integral and differential terms, from a controller 43 scanning by a relay device 41 a plurality of superheater thermocouples, determining the highest metal temperature and comparing it with a set point from the controller 35. A detector 45 determines which error signal corresponds to the lowest firing rate and supplies it to the setting inputs of speed regulators 55A- 55D controlling the motors driving the feeders 25A-25D and to the setting input of a controller unit 65 for the valve 27, feedback is derived from a pressure responsive transducer 67. The set point controller 35 varies the set points of controllers 33, 43 to follow a desired starting programme. The lowest firing rate signal is also fed to a device 101, comprising a plurality of logic elements, Figs. 3-8 (not shown), responsive to the actuation of a switch 93, which is normally open and closes when the firing rate signal is above 95% of its maximum value and of a switch 91 which is normally open and closed when the signal is below 55%. The device 101 determines whether the number of burner groups is appropriate to the load on the boiler and the starting up or closing down of oil and coal burner groups and pulverizing mills in sequence.

Abstract: 839,434. Calculating-apparatus. MICHELL, R. B., and DECCA RECORD CO. Ltd. Jan. 24, 1958 [Feb. 1, 1957], No. 3659/57. Addition to 769,338. Class 106 (1). An astro-navigational apparatus for the reduction of star sights to position lines, taking account of the observer's own motion, comprises a plotting chart 10, a rotatable graticle 13, a time scale bar 17 movable longitudinally in an E.-W. direction across the chart and traversely, but not angularly, and an altitude arm, Fig. 5, freely movable over the chart. The apparatus performs the same calculation as that disclosed in the parent Specification but with the present apparatus, instead of setting a time element along a fixed central time scale and then setting a pivot for the altitude arm at a distance along an angularly set " own motion "arm corresponding to the observer's movement, the zero of the movable time scale is set to a point positioned in relation to the centre of the graticule so as to represent the observer's movement and then the altitude arm is set against the appropriate point on the time scale. As in the prior arrangement, the altitude arm is set, by means of the graticule which is appropriately angularly set, in the direction corresponding to the star's azimuth, and the position line is drawn perpendicularly to the arm at a distance from the intersection of the arm with the time scale corresponding to the difference between the observed and tabulated values of the altitude of the star. The time scale is marked in pencil on the bar 17 in accordance with the latitude, this being facilitated by a diagram on the reverse side of the apparatus. The bar is frictionally held in clips 16 through which pass clamping bolts slidable along slots 15 in the transparent chart-plate 10. The graticule 13 comprises a rectangular grid marked on a disc 12 rotatable on a base-plate 14 between that plate and the chart-plate 10. The altitude arm, Fig. 5, carries a cursor 31.

Abstract: 815,669. Electrical component assemblies; couplings. ERIE RESISTOR CORPORATION. Feb. 4, 1957 [Feb. 17, 1956], No. 3738/57. Classes 37 and 38 (1). An assembly of electrical components comprises ah insulating strip 6 on which a plurality of tubular components, provided with conducting surfaces at their opposite ends, instead of the usual wire terminals, are arranged side-by-side across the width of the strips by means of sheetmetal clips 4, 5 arranged in two parallel rows along opposite edges of the strip, the clips 4, of which one is shown in greater detail in Fig. 3, being provided with extensions 14 which project beyond the corresponding edge of the strip and are formed at their outer ends with prong portions 7 having a curved section so that the complete assembly constitutes a plug-in unit. As shown in section in Fig. 8 the extensions 14 are bent so as to lie alternately above and below the surface of the insulating strip 6 so that the prongs 7 are arranged in two parallel rows and can thus more readily support the complete assembly when it is plugged into a corresponding socket. The assembly is enclosed within an insulating coating which is applied by dipping or moulding over the finished assembly. The assembly may be connected to a printed circuit board provided with terminal apertures into which the prongs 7 fit, the prongs thereafter being soldered to the printed wiring of the circuit.

Title: Method for producing spongy iron
IPC: C21B13/08
Filed: 1930-02-05
Abstract: A method of producing spongy iron by the reduction of ores in the presence of a reducing gas comprises feeding the fine ores together with a binding agent such as an aqueous solution of magnesium chloride or of potassium or sodium silicate into a rotary drum to agglomerate them into balls, separately hardening the balls by passing them through a device heated only sufficiently to harden the binding agent without fusion of the ores, screening the hardened balls and feeding balls of equal size in layers into the reduction furnace.  The ores are moistened with 10 per cent of water and 2 per cent of the binder while being fed continuously through a conveyer worm into a slowly rotating conical drum.  The rolled balls are delivered from the drum by a shaking shoot into the hardening apparatus, consisting of a sloping rotating tube or a conveyer belt in a closed channel heated by a flame or waste gases.

Title: Improvements in electro-mechanical telephone systems and switching apparatus therefor
IPC: H01H67/06
Filed: 1923-02-09
Abstract: 214,373. Baron, H., (Aldendorff, P.). Feb. 9, 1923. Addition to 203,724. Selectors. - Relates to switches of the kind described in the parent Specification which are driven by a continuously - acting force and controlled by the braking action exerted when adhesion is produced between two contacting surfaces, one of which is carried by or movable with the wiper shaft and slides over the other. According to the present invention, the part 6 carried by the wiper shaft 1 is cup-shaped and contacts with a portion of the surface of a relatively-fixed ball 7. The cup 6 is rotated with the shaft 1 through the medium of a yoke 11 which engages two forks 9 extending from a block 8 mounted on the cup 6. The shaft 1 rests in a recess 5 in the block 8 and is insulated from the cup. The ball 7 is mounted on a shaft 13 so that when it is desired to treat its surface it may be rotated in its bearings 12, Fig. 2, by a continuously-rotating iron ring 15 mounted on a diaphragm 16. When a magnet 18 is energized, the ring 15 engages a disc 14 on the shaft 13 and rotates the 'ball 7, a brush 24 mounted in the switch-frame 19 wiping over its surface. The contacting part of the brush 24 may be faced with a hygroscopic material which applies a slight amount of moisture to the surface of the ball. Two other cups 20, 23 mounted on the frame 19 contact with the surface of the bolt 7 and are connected to two of the leads 26, 25 of a three-phase supply, the third head 27 of which is connectable to any of the bank contacts 3. The ball 7 may be made of a semi-conductor, such as agate or Solenhofen slate, and the cups 6, 23, 30 of conducting metal, or vice versa, or both the ball and the cups may be formed of semi-conducting material, for example, the ball of agate and the cups of Solenhofen slate, or vice versa. The shaft 1 may be driven by a spring motor or a small electric motor, such as a three-phase motor individual to the switch, or, if desired, any number of switches may be driven from a common motor. When a circuit is completed over a contact 3, the wiper 2, yoke 11, forks 9, cup 6, ball 7, and cups 20, 23, the cup 6 and the ball 7 bind together and arrest the rotation of the switch. High frequency currents may be used for causing this adherence instead of polyphase or alternating currents. The contacting surfaces of the balls and cups may be enclosed in an air-tight casing or immersed in insulating oil. In switches of the kind shown in Figs. 7 to 9 of the parent Specification in which the contacting surfaces are in the form of discs, surface-treating brushes may be placed in cavities or perforations in the disc contacting with the semi-conductor.

Title: Improvements relating to variable torque converters
IPC: F16C3/28
Filed: 1956-02-09
Abstract: 801,257. Hydrostatic torque converters. ROGER, D. I., [Representative of ROGER, A.]. Feb. 7, 1957 [Feb. 9, 1956, No. 4053/56. Class 69 (2). A torque converter comprises a pump and a motor, each of the oscillating-cylinder type, the pump pistons being actuated by a crank-pin 17, the throw of which is adjustable to vary the output of the pump. Crank-pin 17 is slidable radially of, but rotatable with, a block 11 driven by an input shaft 2. A sun gear 3 fast with shaft 2 meshes with planet pinions mounted in an adjustable carrier 4, the planet pinions meshing with a sun gear 5 fast with a gear 6 meshing with planet pinions mounted in a stationary carrier 7, these pinions meshing with a sun gear 8 provided with an extension 9 having a cam groove 10 co-operating with a pin 16 fast with the crank-pin 17. Relative rotation between the extension 9 and block 11 alters the radial position of the crank-pin 17. When planet carrier 4 is stationary there is no relative rotation, but when the carrier is adjusted through an angle the extension 9 is rotated relative to the block through twice that angle. The planet carrier 4 is adjusted automatically by means of a servomotor 32 which is coupled to the carrier and is acted upon in one direction by the pump output pressure and in the other direction by a manually adjustable spring 33. The cylinders of both the pump and the motor are oscillatably mounted on a stationary plate 20, and the motor pistons co-operate with a fixed-throw crank 28 on an output shaft 29. The pump delivery passes through a reversing valve 24, which can also throttle the flow, to the motor.

Title: Improvements in or relating to electrical automatic tuning circuit arrangements suitable for use on high frequencies
IPC: H03J7/16
Filed: 1946-02-08
Abstract: 608,265. Phase measurement. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Feb. 8, 1946, No. 4054. Convention date, Feb. 9, 1945. [Class 37] [Also in Group XXXVIII] A circuit is automatically tuned to an injected frequency, a change of which causes the circuit to be reduced to a resonant frequency below the injected frequency so that the circuit cannot be tuned to an harmonic of the injected frequency. Automatic tuning.-An oscillator 10, whose frequency is determined by a replacable crystal 12 and replacable tank circuits 16, 18 feeds an amplifier T2 and a circuit 30 to be tuned; oscillations from circuits 18, 30 are applied to a phase discriminator 60 to render one or other of thyratrons 74 conducting according to which oscillation leads in phase; the thyratrons energize the stator windings 80, 82 of a reversible motor which adjusts the tuning element of circuit 30. When the crystal 12 is removed for replacement, contacts 101 are closed to earth line 102 and the grid 71 of valve 60 over contact 103 so that the motor is driven back to its starting position to stop when contact 103 is opened by the motordriven cam 119. Insertion of another crystal opens contacts 101. Where the circuit 30 is tuned by variation of a short-circuit tapping on an inductance, the short-circuited portion may resonate at the crystal frequency when the circuit 30 is tuned to a lower frequency, thus producing spurious tuning; to avoid this, crystals for frequencies above, e.g. 15 megacycles are arranged to close contacts K<11> to earth the grid 69 of valve 60 over contact 117; the motor thus runs to carry the tuning up to, e.g. 15 megacycles, when contact 117 is opened by a motor-driven cam to place the motor under the control of the phase discriminator 60. A further circuit 50 may be similarly tuned by an assembly 90. Phase discrimination.-Oscillations from circuit 18 are applied over leads L, L1 to the grids 69, 71 of vafve 60 in phase opposition; oscillations from circuit 30 are applied over a 90 degree phase shifting condenser 31 and lead L2 (equal in length to leads L, L1) to the cathode of valve 60; a 60-cycle voltage is applied to both grids 69, 71 over resistance 66, so that the output consists of a 60-cycle current whose phase depends on which of the oscillations from circuits 18, 30 is leading in phase.

Title: A method of facilitating the dissolution of high molecular-weight cellulose derivatives
IPC: C08B11/20
Filed: 1955-02-11
Abstract: Particulate cellulose derivatives which are soluble in water or in aqueous solutions of alkali metal hydroxides, and which have a tendency to agglomerate when wetted with water or such solutions, are treated with a proportion of formaldehyde or of a dialdehyde insufficient to reduce the solubility of the cellulose derivative but sufficient to reduce its agglomeration when it is added to water or to aqueous solutions of alkali metal hydroxides.  The cellulose derivative may be an ester such as cellulose sulphate, or an ether such as carboxymethyl, carboxyethyl or sulphoethyl cellulose, or methyl, ethyl, hydroxyethyl or cyanoethyl cellulose or a cellulose ether containing two or more such substituents. The dialdehydes which may be used include glyoxal, malonaldehyde, succinaldehyde, glutaraldehyde, adipaldehyde, heptanedial and octanedial.  In an example, a series of 20 g. portions of granular ethyl hydroxyethyl cellulose, having degrees of etherification of 0.7 and 0.9 with respect to ethoxyl and ethyl groups respectively and a viscosity of 1000 cp. at 20 DEG  C. in 2 per cent aqueous solution, are mixed with a series of dilute solutions of glyoxal in acetone, the percentages of glyoxal based on the cellulose ether ranging from 0.009 to 0.45. The acetone is then evaporated off at 60 DEG  C.  The portions of cellulose ether treated with 0.045 to 0.45 per cent of glyoxal are found to be free from agglomeration when distributed on the surface of water at 20 DEG  C. In other examples cellulose ethers are treated with aqueous solutions of glyoxal or with glyoxal vapour. Formaldehyde is preferably used in the presence of an acid such as hydrochloric or sulphuric acid.

Abstract: 546,511. Flyer spinning spindles; lubricators. FRASER & SONS, Ltd., D., and FRASER, G. S. March 28, 1941, No. 4199. [Class 120 (ii)] [Also in Group XXXIV] - In a wharve-driven flyer spindle having the vertical hollow spindle journalled in upper and lower antifriction bearings in a stationary housing with a suspended flyer and the driving wharve at its upper part, the bearings are lubricated by oil contained in a stationary sump and into which dips a rotor member carried by and coaxial with the spindle, the circumferential wall of the sump being disposed eccentrically to the spindle so that a convergent passage is formed between a segment of such wall and the periphery of the rotor member and the oil is swept frictionally by the rotating member into the passage and through a duct communicating therewith and from which the oil flows to the upper bearing. As shown the rotor member is a thimble 8 mounted on the hollow spindle 1 and disposed with its skirt portion partly immersed in the oil in the sump 7 formed within an integral base part of the stationary housing 4. Rotation of the thimble 8 sweeps the oil into the passage 10 between the wall 9 of the thimble and the wall 13 of the sump and forces it through a port 11 communicating with the duct 12 leading to the upper bearing 6 to which it passes through a port 14 disposed at the lower end thereof; the oil passes from the upper bearing through a port 17 to the annular space 18 between the bore of the housing and a tubular distance piece 19 and flows through the lower bearing 5 to the sump 7. In a modification the sump is formed in an annular plug screwed into the base of the housing and the oil from the duct 12 flows through a port disposed at the upper end of the bearing 6; a screw 25 may be provided for regulating the flow of lubricant through the port 11. The wharve 3 has a central depending boss 21 screwed on to the upper end of the spindle 1 and by removing bolts 24 the whole flyer assembly may be removed as a unit from the rail 23.
