IPC: H01J40/14
Filed: 1933-06-28
Abstract: 399,767. Valve circuits. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Cockrell, W. D. ; 1, Rugby Road, Schenectady, New York, U.S.A.) June 28, 1933, No. 18412. Convention date, June 29, 1932. [Class 40 (v).] An arc discharge device 3 energized by alternating current over lines 1, 2 controls a relay 7 in its plate circuit and is controlled by a photo-electric cell 14 in its grid circuit, the current supplied to the cell 14 leading in phase that supplied to the plate circuit, and the grid having a negative charge when the voltage on the plate is zero. The cell 14 receives its current over a condenser 16 and a voltage divider 20, the phase change produced by the condenser 16 being sufficient to cause the discharge device 3 to pass current at the beginning of the half cycle upon which it operates, if the cell 14 is exposed to light. To prevent operation due to transients and when the cell is dark, a secondary winding 21 of a transformer across the supply lines 1, 2, is connected to the grid over a condenser 24, so that grid current flows during negative half cycles of the supply to produce a negative charge on the grid when the supply voltage is zero.

Title: Method and apparatus for compensating recorded phase modulated control signals
IPC: G05B19/42
Filed: 1968-04-19
Abstract: 1,209,976. Programmed electric control. BENDIX CORP. April 19, 1968 [April 28, 1967], No. 18637/68. Addition to 1, 098, 048. Heading G3N. To compensate for phase errors in a control system employing a reference wave and a phase displaceable wave, one wave is passed through a filter having characteristics substantially identical to the operating system, the output from which is compared either with the filter input or the other wave to develop an error signal which provides a correction voltage. The filter may be a resolver. Signals from a punched tape reader (12) Fig. 1 (not shown) are converted into pulse trains in a known controller (16) one for each axis and passed through counters (24, 26, 28) together with constant frequency reference square pulse signals to a recording head (38). On playback the reference signal squarewave is amplified at 72 passed through a discriminator 78 which produces a pulse train representative of the zero crossings of a 0 degree wave and a 90 degrees wave generated at (50) Fig. 1. The 0 degree wave is fed directly to one input of a flip-flop 84 and indirectly through an inverter 86 to the other input, the flip-flop output being passed through an amplifier 92 to one stator coil 96 of a resolver 110. The other stator coil 98 is fed by a similar circuit from the 90 degrees wave through a flip-flop 88 which has a second output, both outputs passing to a detector 138. Outputs from flip-flops 84, 88 are also passed to stator coils of a calibrated resolver 134, the rotor coil being connected through a filter 136 to the detector 138, which gives an output proportional to frequency change from the 0 degree signal. Each co-ordinate signal e.g. the X axis signal, is passed through an amplifier 74 and flip-flop 120 to another detector 118 to which is fed the output from rotor coil 112 through a filter 115, and the output controls the X axis servomotor together with a correction voltage from detector 138. The detector circuits, which are identical, are described with reference to Fig. 3 (not shown).

Title: Method and apparatus for deep-bed charging of travelling grates
Inventor: MCDOWELL ROBERT CHARLES
IPC: C22B1/20
Filed: 1959-06-01
Abstract: 919,600. Sintering ores. McDOWELL CO. Inc. June 1, 1959, No. 18645/59. Class 82 (1). A method of charging a sintering machine with a deep bed comprising finely-divided material mixed and formed into pellets of varying sizes and loose particles consists of mixing the material to make it uniform and so conveying it to moving pallets and applying it by many applications so as to spread it from side to side and upwardly and downwardly and along a gradual slope corresponding to the angle of travel of a thin firing zone created by ignition of the bed at the bottom in updraft operation and causing the zone to move upwardly, or at the top in downdraft operation to cause it to move downwardly. A thin grate-bed or covering of suitable material is first ignited and updraft is preferably applied to promote firing. In an apparatus for charging the machine (Figs. 3 and 4), the pellets are made preferably in balling-discs 12, gathered on a belt 15 discharging upon a belt 18 extending through a hood H and delivering to a reciprocated conveyer belt 20, for spreading a combustible layer C on a conveyer 1 to form a bed B, mounted on a slope, by means of a frame 23. The frame 23 supports end rollers 22 and 24 and is supported to be reciprocated on a carrier formed of members 28 having rollers 29 embracing the flanges of a sloping mono-rail track 30, to be driven by a cable 34 attached to the frame 23, the belt 20 being made to travel along the track by any suitable mechanism, the forward end thereof being moved along to form a slope S. The delivery end of the frame 23 may carry distributing means, e.g. a pivoted shoot 35, and means for oscillation to distribute the material. The angle of the conveyer slope is such that the pellets and particles do not roll and the reciprocation is timed to give thin applications. Further additions of fuel can be made by various methods to increase its content. The conveyer 1 comprieses pellets having outside walls 2, and below it is a windbox W. A grate-covering of previously-fired pellets is fed from a shoot 4 and ignited at 5 before the material is fed. In a modified form (Fig. 7), the reciprocating belt 20a, which is cooled somewhat, has a portion extending upwardly outside the hood H, the pulley 22 is carried on a frame supported by a sloping rail 30 and the frame carries the material spreader, e.g. a shoot. The upper and lower reaches of the belt 20a turn around pulleys 50, 51 out of the hood and pass over an external pulley 53 moved up and down as the frame and pulley 22 move up and down along the slope. The pulley 53 may be power-driven at variable speed by a motor 58 and is carried by a support 55 counter-balanced by a weight 56 on a cable passing over a drum 57 variable in speed.

Filed: 1933-07-04
Abstract: 422,056. Road signals for controlling traffic. AUTOMATIC ELECTRIC CO., Ltd., Strowger Works, and HARRISON, H. H., 15, Mayville Road, Mossley Hill, both in Liverpool. July 4, 1933, No. 18959. [Class 118 (ii)] An electric motor is used to time road traffic control signals of the vehicle-actuated type, control times being effected by altering the speed and/or the direction of rotation of the motor. As shown, an induction disc D is driven by coils A, B and C. The coil C being fed through condenser K to give the required phase displacement. The speed of the disc is regulated by magnetic brake BM which is fed through resistance R, the effect of the brake being adjusted by altering the resistance. The operation of relay RA removes the brake and reverses the direction of rotation of the disc. As applied to the system described in Specification 409,376, the motor is started by vehicles on the road not having right of way and the resistance in the brake circuit depends on the cam contacts closed. A vehicle on the route having right of way operates relay RA to remove the brake and reverse the motor so that it returns to the zero position as quickly as possible. The motor transmits impulses to the solenoid driving the camshaft controlling the signal changes. Instead of an induction disc type motor a direct current motor may be used, a field control replacing the magnetic brake.
