Inventor: LAW HILTON
Filed: 1956-06-14
Abstract: 821,108. Automatic speed control systems. ENGLISH ELECTRIC CO. Ltd. June 14, 1957 [June 14, 1956], No. 18370/56. Class 38 (4). In an electric frequency control system comprising a frequency-responsive circuit having a capacitive impedance 25, an inductive impedance 26, adjustable voltage-dividing means 27, 28 for supplying one of the impedances with an adjustable proportion of the voltage developed across the other impedance when the latter is supplied from a variable frequency A.C. source such as a tachometer generator 21 coupled to motor 20, and a phase discriminator 30 arranged to produce an output signal dependent on the deviation in phase of the resultant of the currents flowing in the respective impedances from a predetermined datum, control means 23 are arranged to control the speed of motor 20 and thereby vary the frequency of the A.C. supply in accordance with the output from the discriminator in a sense tending to reduce the deviation in phase, variation of the controlled frequency being obtained by adjustment of ganged wipers 27a, 28a on the auto-transformer voltage dividing means. The resultant currents are applied to phase discriminator 30 by a centre-tapped autotransformer 29, and a current in phase quadrature is applied over transformer 31. Amplifier 24 to which the discriminator output is applied may be compensated for the increase of input with increased motor speed. Modified embodiments described with reference to Figs. 2, 3 (not shown), include a further auto-transformer of variable ratio in cascade in the tachometer output, the wiper of which is ganged with the wipers of the other transformers in order that the loop gain may be made constant or otherwise regulated for any change in desired frequency, and a voltage regulator controlling the voltage at terminals 21c respectively. An embodiment employing a single-phase tachometer in which the quadrature feed to the discriminator is taken from across a large inductance in series with a resistance is described with reference to Fig. 4 (not shown). Other modifications referred to include reversing the positions of the capacitance and inductance, replacing the auto-transformers with potentiometers, and dispensing with one of the two auto-transformers.

Title: An installation comprising self-opening separators for the separation of sludge containing liquids
IPC: B04B1/18
Filed: 1937-07-06
Abstract: 483,438. Centrifugal separators. AKTIEBOLAGET SEPARATOR. July 6, 1937, No. 18749. Convention date, July 18, 1936. [Class 23] An installation of separators 18 for the treatment of sludge-containing liquids is controlled by a regulating arrangement, so that when a suitable amount of sludge has been collected in each bowl it is ejected through peripheral ports which are then closed for continued operation. The bowl 1 of a separator has a sludge discharge port 2 which is opened by an hydraulically operated slide 3 after it has opened a channel 4 for the discharge of remanent liquid from the bowl. A tube 6 from the sludge space normally discharges liquid, through the chamber 8 to the vessel 9 from which the flow passes through the opening 11. This chamber 9 is on a balance arm and as long as the bowl works normally, the weight of the chamber is balanced by the weight 12. When, however, sludge accumulates in the bowl and the tube 6 becomes clogged, the liquid flow is diminished and the weight 12 drops to close the contacts 13. This closes the circuit of the motor 15 through a relay 14 and thereby causes the rotation of a number of cams 17 which act on contacts 17a. Circuits are closed to operate the valve A to cut off the supply from all the separators 18 and to open the valves 19 to move the slides 3 downwards for the discharge of sludge. Afterwards the valves 19 are closed and the valves 20 are opened to restore the slides to working position and the valve A is opened for the supply of liquid to the bowls 18.

Title: A device for producing a controlled a.c. signal in response to variation in a d.c. current
IPC: G01R17/02
Filed: 1962-05-17
Abstract: 1,011,393. Photo-electric measuring devices; voltage and current measurement. INSTRUMENT FABRIEK EN HANDEL VOORHEEN P. J. KIPP & ZONEN N.V. May 17,1962 [May. 29, 1961], No. 19001/62. Headings G1A and G1U. An arrangement for recording the D.C. current fed in at an input 2 to the moving coil of a galvanometer type instrument makes use of a periodically reversed galvanometer magnetic field to avoid errors due to lack of balance. As in known arrangements using a constant magnetic field, the galvanometer may carry a mirror the position of which is sensed by the use of a beam of light from source 4 directed on the mirror by lens 3 and reflected from it towards two adjacent photo-resistors 5. These are coupled in a bridge circuit fed from D.C. source 7. Unless no current is flowing in the galvanometer coil periodic reversal of the magnetic field (which may be provided by an electromagnet) will cause an A.C. output from the bridge circuit which is used, after amplification, to drive motor 9. The motor controls the recorder and also the slider of potentiometer 10 until the latter feeds back a voltage equal and opposed to that causing the current flow through coil 1. The coil then ceases to move and the A.C. bridge output falls to zero. Any D.C. output from the bridge, due to lack of balance in the system, is blocked by capacitor 13. In another embodiment (Fig. 4) the moving coil of the first galvanometer is mechanically coupled to position the coil 14 of a second galvanometer having a constant magnetic field. The currents induced in the coil 14 as it moves with coil 1 are amplified and used to control a motor 9 operating as in the previous embodiment.
