Filed: 1976-01-13
Abstract: 1526311 Arc furnace ASEA AB 13 Jan 1976 [14 Jan 1975] 01154/76 Heading H5H Deflection of the arc 9 in a D.C. furnace with an asymmetrical hearth electrode 5 caused by the field produced by the hearth current is obviated by the use of at least one so called compensating conductor 8 arranged at least partly below the furnace and in series with the arc current so that it produces an opposing magnetic field to the hearth current. This arrangement is self-regulating at different arc currents. A magnetic core 10 associated with the conductor 8 may be adjusted relative the non-magnetic bottom of the furnace to vary the compensating magnetic field. A four pole arc rotating A.C. magnet may be provided beneath the furnace as in Specification 1,505,381. Cores provided for each pole serve two functions; as cores for the rotating magnet and as cores for the compensating conductor. Double coils of suitably orientated compensating conductors may be placed beneath large furnaces. Alternatively, the arrangement shown in Fig. 3 may be used. Two parallel conductors 8 beneath the conductor are connected in series with diametrically opposed horizontal conductors 17, 18 arranged around the upper part of the furnace. The horizontal conductors 17, 18 are vertically adjustable on vertical interconnecting conductors 15, 16, 19, 20 to vary their effect on the arc. All of the conductors shown, 8, 15, 16, 17, 18, 19 and 20 influence the arc.

Title: Improvements in controlling devices for exhaust steam injectors
IPC: F04F5/46
Filed: 1926-01-15
Abstract: 251,212. Metealfe, R. D., and Metcalfe, J. G., (Hard, M.). Jan. 15, 1926. Giffard injectors; controlling action.-In an injector adapted primarily for operation by exhaust steam and having a valve controlling the admission of supplementary live steam to the injector, means are connected to the valve for throttling the supply of live steam when the valve is moved to its full opened position. The control valve spindle 24 is operated by a handle 25 and actuates two valves coupled together bv a lost-motion connection. The valve 26<a> is between the live-steam conduit 21 and a passage 28 leading by a pipe 30 to the supplementary, live-steam nozzle 14. The valve 26<a> is guided by radial blades 26<c> secured to a head having a lost-motion connection with a valve 26b controlling the passage of live steam to a chamber 31 opening into a chamber 32 in which is a valve 33 having upper and lower seats 34<a>, 34b. This valve is controlled by exhaust steam pressure acting through a pipe 37 on the upper face of a member 36. If. when the valve 26b is opened, there is exhaust pressure in the pipe 37, the valve 33 is held down on its lower seat and live steam passes by a pipe 42 to a chamber 43, lifting a member 18 and opening a valve 17 admitting exhaust steam to the nozzle 11. If, when the valve 26<b> is opened, there is no pressure in the pipe 37, the valve 33 is raised by the live-steam pressure and live steam passes by a pipe 40 to a nozzle surrounding the nozzle 14. The radial guides 26<c> of the valve 26<a> carry a sleeve 45. Should the operator throw the valve 26<a> wide open, this sleeve throttles the passage 28 leading to the nozzle 14.

Title: Improvements in and relating to electric braking systems
IPC: B60L7/04
Filed: 1942-01-30
Abstract: 555,069. Control of D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 30, 1942, No. 1274. Convention date, Jan. 31, 1941. [Class 38 (iii)] During dynamic braking of a vehicle, motors 10, 11 are connected in a loop with braking resistors 71, 72, and their fields 12, 13 are connected in series with an axle-driven exciter 35 across the resistor 72. The excitor is regulated for constant voltage by a vibrating regulator 41, and opposes the back voltage of the motors. As the back voltage of the motors declines, their field excitation increases and so the braking effort remains substantially constant. During motoring, controller 18 is used, line-breaker LB is picked up and series-parallel transition is given by notches 19-28, 29. The regulator 41 maintains a constant low voltage at the brushes of the exciter so that it will build up quickly when braking is required. During braking, pedal 43 is used, braking contactors B1, B2 are picked up and setting of regulator 41 is changed by removing a short circuit about resistor 48, so that exciter 35 is regulated for full voltage.

Title: An improved electric testing and measuring arrangement of the bridge type
Inventor: DEAN NOEL SPENCER
IPC: G01R23/14
Filed: 1951-01-19
Abstract: 690,067. Bridge circuits. BRITISH INSULATED CALLENDER'S CABLES, Ltd. Jan. 18, 1952 [Jan. 19, 1951], No. 1533/51. Class 37. A bridge is fed by a source of beat frequency current derived from two oscillators, one of fixed frequency and one of variable frequency, and the output from the bridge is linked with the variable frequency oscillator to produce by a heterodyning process current of constant frequency. The bridge network 7 is arranged for testing a circuit element contained in one arm over a range of frequencies from 50 kc/s. to 6 mc/s. The source of current is a fixed frequency-oscillator 1 working at 10 mc/s. and a variable frequency oscillator 2 working in the range 10.05-16 mc/s. The outputs of the oscillators 1, 2 are combined in a mixer 3, the output of which includes a beat frequency in the range 50 kc/s-6 mc/s. The output from the mixer 3 passes through a low-pass filter 4 having a cut-off frequency of 7 mc/s., thus leaving only the beat frequency components in the range 50 kc/s.-6 mc/s. The output of the filter 4 is passed through a wide-band amplifier 5 to the primary winding of a transformer 6, the secondary of which is connected across one diagonal of the bridge network 7. The output from the other diagonal of the bridge is passed through a wide-band amplifier 8 to a mixer 9, which also receives current at frequency in the range 10.05-16 mc/s. from the variable oscillator 2 through a filter 10. This rejects current at a frequency of 10 mc/s. and thus prevents current from the oscillator 1 being fed to the receiver. The output from the mixer 9 is always at a frequency of 10 mc/s. and is passed through an intermediate frequency amplifier 11 and heterodyned with the output from a local oscillator 12 working at 10.001 mc/s. This is followed by a mixer detector 13 giving an output of 1 kc/s. which is passed through an amplifier 14 to a telephone 18 or an ammeter, or cathode-ray tube. In a modification an intermediate frequency in the receiver circuit is 35 mc/s. instead of 10 mc/s. in order to reduce the possibility of coupling with the fixed frequency oscillator 1. This is produced by heterodyning the output of the variable frequency oscillator 2 with a second fixed frequency oscillator and passing through a filter which rejects current at a frequency of 35 mc/s., which is passed to the mixer 9 and produces an output at a constant difference frequency of 35 mc/s. The oscillator 1 may be crystal controlled, and the rejection filters may also be of the crystal type.

Abstract: 362,731. Optical recording of electrical oscillations. KOLSTER-BRANDES, Ltd., Cray Works, Sidcup, Kent.-(Kolster Radio Corporation ; 200, Mount Pleasant Avenue, Newark, New Jersey, U.S.A.) Jan. 16, 1931, No. 1548. [Class 40 (ii).] A system for the optical recording of electrical oscillators, such as for recording telegraph signals and sounds upon films, comprises an armature member supported on a magnet and suspended in the permanent magnetic field thereof by virtue of the line of force threading said armature, an electromagnetic control device positioned near the armature causing displacement of the latter so that a light-reflecting surface carried by it deflects a light beam in accordance with the electrical oscillations which are to be recorded. An armature 1 is mounted in a vertical position between the poles of a permanent magnet 2 by virtue of the lines of force threading through it. The lower end of the armature 1 is provided with a knife-edge 3 fitted into a recess 4 in the pole member 6 of an electromagnetic control device 6, the winding 7 of which is connected to the source of electrical oscillations. The armature 1 carries a prism 10 at the top in alignment with an aperture 11 formed in the magnet 2 so that light from a source 20 may be reflected to impinge on a photographic film 24. The aperture 11 is recessed at 12 to receive a ring member 14 of copper, brass, or aluminium, in which eddy currents may flow to damp the motion of the armature. The damping means may also comprise a rubber pad 15, Fig. 4, held in position by a member 16 mounted on the south pole of the magnet 2, or alternatively a rubber damper may be fitted over the polepiece 6 against which the armature 1 may cushion. Variations in the magnetic conditions of the system 6 cause the armature 1 to oscillate and deflect the light rays 22, which impinge upon a light-sensitive film to effect a record of the electrical oscillations.

Abstract: 1298243 Automatic control of travelling sheet INDUSTRIAL NUCLEONICS CORP 13 Jan 1970 1697/70 Heading G3R The average value of a property e.g. a thickness, over substantially each half of the width of a travelling sheet of material, and over an overlapping central area, respectively control the relative or absolute values of the properties in zones upstream of the measuring point. In Fig. 4, rubber tyre fabric 4, after calendaring between rolls 25, 29, is scanned transversely by a gauge 40 which produces, at 7, electrical signals corresponding to thickness. A programmer 10, responsive to the position of the gauge, causes an analog or digital computer 8 to separately average thickness over approximately each half of the sheet, and a further computer 11 to average thickness over a central section which overlaps portions of the two halves. The averages are stored at 14 and 15 and applied to appropriate times through a switch 17 for comparison with desired values at 18 so that the appropriate screwdown motor 28 or 30 is operated to correct errors in the corresponding half, and a motor 32 is operated to skew the lower roller about a vertical axis and thereby equalize the thicknesses of the central and outer portions of the sheet if any difference is detected by the comparator 16. The latter control only takes place when the thickness errors in the two halves of the sheet have been reduced below predetermined values. Roll bending instead of skewing, and measurement of weight per unit area instead of thickness, are referred to.
