Title: Improvements in or relating to electrical protective relays

Filed: 1960-07-20
Abstract: 987,974. Protective arrangements. ENGLISH ELECTRIC CO. Ltd. July 14, 1961 [July 20, 1960], No. 25283/60. Heading H2K. [Also in Division H3] A polyphase time-overcurrent relay arrangement, e.g. for an induction motor RL, comprises a phase sequence filter, rectifiers Bp, Bn and a series-parallel resistance network R7 . . . R9 for deriving a unidirectional relay operating current dependent on a combination of the positive and negative phase sequence components of the current taken by the motor. When a capacitor C3 is charged by the relay operating current to a predetermined value, the transistor amplifier T2, T3 of Specification 958,774 energizes a protective relay AUX. The charging of the capacitor C3 is controlled by a transistor T1 which under normal load conditions is conducting, due to a positive bias applied to its base by means of resistors R15 ... R17, and permits the capacitor to acquire a standing charge dependent on the voltage across a resistor R14 and a diode D3 in series with the transistor T1. When an overload occurs, a sufficiently high negative potential exists across a resistor R11 and diode D1 to stop the transistor T1 conducting and the capacitor C3 is charged fully by the relay operating current to effect operation of the relay AUX. When the motor is switched off, any charge in the capacitor C3 is slowly discharged through a diode D4 and a resistor P6 providing a long time reset. Thus should an overload fault condition exist when the motor is first switched on, the transistor T1 does not conduct and as the capacitor has no standing charge, a longer time elapses before relay operation occurs. Thus the relay arrangement provides " hot " and " cold " characteristics similar to those of a thermal overload relay.

Abstract: 1469127 Testing system BLAUPUNKTWERKE GmbH 7 June 1974 [9 June 1973] 25483/74 Heading G1U [Also in Division H4] In a broadcast traffic information system incorporating a number of broadcasting stations which may each transmit in addition to normal programme entertainment, traffic announcements to motorists, each station radiates a pilot tone, preferably at 57 kc/s, and each such pilot tone is modulated by a frequency at or below the VHF transmission band identifying the particular transmitting station. When an announcement is actually to be transmitted, an additional modulating frequency which is the second harmonic of the identifying frequency and is phase locked to it is also transmitted - this can be detected to indicate the occurrence of the announcement. The detecting arrangement in the receiver operates by differentiating the demodulated signal, applied at 10, then, after amplification at 12, applying the demodulated signal via an integrating network 24, 26 to one input 25 of a differential amplifier. The opposite peak values of the differentiated signal are also detected by diode-capacitor arrangements 17-18 and 16-19 and their difference applied to the other side 27 of the differential amplifier. In the presence of the second harmonic, the differential amplifier is unbalanced and the signal applied via transistor 29 turns on the transistor 34 and illuminates the lamp 35.
