Title: Apparatus for explosion protection for hydrogen-cooled generators
IPC: H02K9/24
Filed: 1960-11-22
Abstract: 895,271. Cooling dynamo-electric machines. GENERAL ELECTRIC CO. Nov. 22, 1960 [Dec. 18, 1959], No. 40135/60. Class 35. In an explosion protection apparatus for the gas changing cycle of a hydrogen-cooled generator, a gas analyser is used to analyse the gases in the exhaust conduit of the generator and to operate an alarm if more than 4% of hydrogen or more than 5% oxygen is present in the conduit. The generator 1 is first purged of air by connecting an inert gas supply 9 to the generator through valve 11, conduit 4 and distribution tube 2, forcing the air into the chamber 15 via conduits 5, 6 and valves 14, 8. The percentage of hydrogen in this exhaust is monitored by analyser 17. Hydrogen is introduced to the generator by reversing valves 11, 14 and monitoring the percentage of oxygen in conduit 6 (Fig. 2, not shown). In a modification, both a hydrogen and an oxygen analyser are connected in series with an alarm, the circuit being completed when the safe percentages of 4% hydrogen and 5% oxygen are exceeded (Fig. 4, not shown).

[Also in Group XXXVI] In an arrangement for checking the ageing of unattended repeaters in a 2-wire carrier system in which two continuous alternating voltages of different frequencies lying in the Go or Return band are transmitted from one terminal station and intermodulation products are selectively returned from the repeaters, the two frequencies are so chosen as to form intermodulation products lying below the Go and Return bands, a band-pass filter BP is connected between the active part AV of each repeater and its lowfrequency shunt NFU, the band-pass filter BP of each repeater being tuned to a frequency below the Go and Return bands which frequency is characteristic of that repeater, and means is provided to prevent the frequency which is characteristic of any repeater from being produced by any other repeater. As described, the invention is applied to a system in which the Go band (A-B) is 24 to 224 kc/s. and the Return band is 312 to 552 kc/s., the directional filters TP1, TP2 and HP2, HP1 passing the respective bands in association with the common amplifier AV, feed current for which is transmitted via the low-pass filters of the power supply circuits S1 and S2 in the low-frequency shunt. These circuits also include high-pass filters which pass the frequencies below 24 kc/s., and the band-pass filter BP is connected between the output of the amplifier AV and the junction of these two high-pass filters. The two frequencies transmitted from A or B are so chosen that the intermodulation product of frequency less than 24 kc/s. falls within the pass-band of the filter BP of the repeater to be tested. The directional filter TP2 of each repeater is designed as a band-pass filter which rejects frequencies below 24 kc/s.

Abstract: 1406971 Number sending devices; oscillators PHILIPS ELECTRONICS & ASSOCIATED INDUSTRIES Ltd 12 Sept 1973 [15 Sept 1972] 42784/73 Headings H4K and H3T An oscillator includes an amplifier with negative feedback, and positive feedback via an RC circuit, characterized in that the frequency is selected by switching resistors into the RC circuit and in that the resistor values are such that if two switches are operated simultaneously the resulting attenuation in the positive feedback path is greater than the amplification of the amplifier. In the multifrequency dialler shown two oscillators 10, 11 are powered from the line a-b via a 'constant current arrangement 26 to 41 and supplied with a D.C. voltage via transistor 58 and resistor 59. Depending on which one of switches 12 to 15 is closed oscillator 10 produces a first frequency while depending on which one of switches 16 to 19 is simultaneously closed (by operation of a single digit button) oscillator 11 produces a second frequency of a higher group. The two frequencies are combined at potential divider 20, 21 which attenuates the first frequency relative to the second and amplified at 22, 46 and 23. Oscillator 10 for example comprises two amplification stages 47, 48 and 49, 50 and has current feedback in the second stage via resistors 51, 52 and voltage feedback over both stages via a transistor 54 and comprising negative voltage feedback to the base of transistor 49 and negative voltage feedback to the base of transistor 48. Depression of a key causes a D.C. level change which is restored on release. The leading and trailing edges may be used in the substation to perform auxiliary functions such as putting the microphone out of operation, connecting up the receiver such that the dialling signals can be heard, or removing a short circuit for alternating currents from the output.
