Title: Improvements in protective systems for dynamo-electric machines
IPC: H02H7/085
Filed: 1932-06-08
Abstract: 400,710. Automatic regulation; protective arrangements. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Burnham, E. J. ; 305, Root Avenue, Scotia, and Slinger, R. N. ; 524, Pennsylvania Avenue, Schenectady, both in New York, U.S.A.) June 8, 1932, No. 16222. Convention date, June 8, 1931. [Class 38 (iv).] Overheating of dynamo-electric machines, such as synchronous condensers, is prevented by means responsive to the resistance of the field windings operating with time delay action to limit the field winding temperature by reducing or limiting the excitation produced by the operation of the automatic field regulator. A voltage regulator according to Specification 388,805 has a resistance 6 and reversible motor with relays 11, 12 for obtaining gradual changes and relays 7, 8 for obtaining quick changes in the excitation of the field of an exciter of a synchronous dynamo-electric machine 1 and these are automatically controlled in accordance with voltage conditions of the machine 1 by a spring-biased three-phase torque motor 19 operating pairs of contacts 20, 21 and 22, 23 in conjunction with a continuously rotated contact member comprising an interrupted surface 24 and a continuous surface 25, the former controlling gradually the resistance 6 and the latter rapidly the resistances 5, 6. According to the invention a relay 28 is operated by differential windings 31, 32 excited respectively in accordance with the voltage and current of the field winding 2 of the machine 1 so that at a particular resistance, and therefore temperature, of the field winding, contacts 33 are closed and the winding 30 of a time-delay relay is energized. Operation of this relay opens at contacts 35 the circuit of the relay 8 and prevents quick increase of excitation and closes at contacts 36 the circuit of an alarm device. A relay 29 responsive to field current opens contacts 41 in parallel with contacts 39 on the relay 30, thus preventing operation of the slow increase relay 11, and closes contacts 40 in series with contacts 38 in the relay 30 whereby a slow decrease of the field excitation is initiated. The energization of the current coils of the relays 28, 29 is not limited to the instrument-shunt method shown and the current relay 29 may be responsive to the main line current of the machine 1.

Title: Improvements in and relating to the measurement of the frequency of electric waves
IPC: G01R23/00
Filed: 1935-06-07
Abstract: 457,820. Frequency measurements. STANDARD TELEPHONES & CABLES, Ltd., and TERRY, V. J., 63, Aldwych, London. June 7, 1935, No. 16593. [Class 37] [See also Group XXXVIII] An arrangement for indicating the frequency of electric waves comprises a single discriminating network having an efficiency variable with frequency, a limiting circuit connected to the input of this circuit and giving a substantially constant voltage of the fundamental component, and an instrument for indicating the output of the network. The source 1 is connected through impedances 2, 6 to the primary winding 4 of a transformer 3. The secondary winding 5 is connected to the primary winding 12 of a second transformer 11, condensers 8, 10 being connected in series to a gaseous discharge device such as a neon lamp 8 in shunt. The secondary winding 13 of the transformer 11 is connected to the input terminals 15, 16 of a discriminating network 14, in series with the impedance 6. This introduces a voltage into the circuit of the secondary winding 13 of such magnitude and phase as to compensate for the departure from constancy of the output of the gaseous discharge device. The condensers 8, 10 prevent any rectifying action of the neon lamp 9. The phase and magnitude of the compensating voltage across the impedance 6 may be varied by altering the magnitude of the condensers 8, 10 or by inserting an impedance in series with the neon lamp. The discriminating network 14 consists of a low-pass filter having an attenuation proportional to the frequency over a certain range, which can be increased by connecting resistances in series with the filter. A full-wave rectifier is connected in the output of the filter and supplies to the output terminals 17, 18 a voltage proportional to the frequency. A moving coil ammeter 19 gives a deflection proportional to the frequency. In indicating systems in which the movement of a pointer or other indicator is caused to change the frequency of an oscillator, the oscillations are combined with those of an oscillator of fixed frequency and the difference frequency is transmitted to a receiving station and is there connected in place of the source 1 through a filter circuit to cut out harmonics. The pointer of the instrument 19 then follows the movements of the distant pointer.

Abstract: 1,189,292. Photo-electric sound producing instruments. D. ORAM. 10 April, 1967 [15 April, 1966], No. 16684/66. Heading G5J. An apparatus for generating oscillations of varying frequencies and waveforms comprises an electro-optical device recurrently scanning a graphical or variable density representation of the waveform, means for varying and digitally controlling the scanning velocity and a transducer energized by the generated electric oscillation. As shown in Fig. 1, a sinusoidal wave 16 is drawn on a film strip 13 in front of the face plate of a cathode ray tube 10, and a photo-electric device 17 receives light through transparent areas of the film above the line 16. The output of device 17 is applied through a feedback amplifier 18 to the Y-deflection plates of tube 10, the feedback being arranged so that the scanning spot follows curve 16 and the output derived from amplifier 18 is applied to a loud-speaker 20. The scanning recurrence frequency of time-base 11 is variable by a control 12. A low pass filter may be provided between the scanner and transducer to reduce high frequency transients generated by the flyback. Alternatively the graphic waveform may be on a closed circular loop and a circular scan provided. The digital control of the scanning velocity may be effected by the arrangement shown in Fig. 2 in which a strip 23 having different combinations of inked-in sections at different locations passes between a housing 32 containing five lamps and a housing 33 containing five photo-electric devices, to provide different combinations of pulses to shift the frequency of a linear time-base by switching in various resistance-capacitance circuits (Fig. 4, not shown). A photo-electrically controlled variable gain amplifier (70, Fig. 5, not shown) between scanner 22 and loud-speaker 20 provides a volume control. A plurality of scanners, each providing oscillations of different frequencies and waveform may be selectively connected to a loud-speaker 20 by photoelectrically controlled switches (Fig. 6, not shown). Other forms of transducers, for example, a magnetic recording head, may replace loud-speaker 20. The frequency control may be of more complex digital form. The waveform carrier may be of light reflecting material.
