IPC: H04W88/02
Abstract: 773,170. Radio signalling. PHILIPS ELECTRICAL INDUSTRIES, Ltd. June 10, 1955 [June 15, 1954], No. 16750/55. Class 40(5) In a F.M. radio communication system between a central transmitter/receiver and a number of mobile transmitter-receivers, all the mobile 'receivers are normally muted, but are rendered operative by a short burst of 2,900 c/s tone transmitted from the central station prior to announcement of a call for a particular mobile unit, then a short burst of 2,750 c/s tone from the central station again mutes all mobile receivers except the selected one, who, it is assumed, overides the muting circuit. At the central transmitter, Fig. 1a when a calling key S is closed, a system of relays A, B, C, D Fig. 2 (not shown) is so arranged that relay B connects the tone generator 25 to the modulator 2 of the transmitter over contacts b<SP>1</SP> for about 0-5 to 1 second, to transmit the 2,900 c/s release tone, then b<SP>1</SP> changes back to the position shown and so reconnects the hand set 11 to the transmitter. An announcement calling a particular mobile unit can now be made. Meanwhile relay D has closed contacts d' to change the frequency of the tone generator 25 to the 2,750 c/s muting tone. On releasing the calling key, relay B again connects the tone generator 25 for 0.5 to 1 second to transmit the muting tone. Finally the relays re-set to their starting position, with the handset 11 connected to the transmitter and the tone generator switched for the release tone. At each mobile unit, Fig. 1b, filters 34, 35 are tuned to the release tone and the muting tone respectively and their rectified outputs are applied in opposition to a normally cut-off triode 49 controlling the muting relay 51. Reception of the release tone applies a positive bias to triode 49 relay 51 pulls up and connects the loudspeaker 55 to the receiver over contacts 54<SP>1</SP> and the triode is held conducting over contacts 50<SP>1</SP>. The announcement from the central station is now received, and if appropriate, the hand set 58 is lifted and its hook-switch bypasses the muting circuit over contacts 57. Reception of the muting tone cut-off triode 49 and restores the muting circuit thereby again muting all mobile receivers except the one at which the hand set has been lifted.

Title: Method for determining overhaul life of gas turbine installation
IPC: F01D21/00
Filed: 1979-04-27
Abstract: The method for determining the overhaul life of a gas turbine installation consists in determining the critical elements of the gas turbine installation, whereupon the overhaul life is dependent, recording the time of onset of threshold failure values of these critical elements with reference to a combination of continuously recorded thermodynamic parameters of the working cycle, vibration and discharge characteristics, capacity and life behaviour characteristics with due regard for the duration of action of each of these factors, measuring the rate ( lambda i) at which faults of the critical elements develop to reach their critical values, and determining the equivalent rate ( lambda (To)) of failure development in the gas turbine installation as a whole, which, in turn, serves to calculate the overhaul life (To) of the gas turbine installation. The invention is applicable to turbine installation diagnosis systems, such as those used to diagnose the operating state of gas pumping plants.

Patent GB-2079911-A (GB)
Title: Tumble dryers
IPC: D06F34/26
Filed: 1980-06-05
Abstract: The control circuit of the tumble dryer includes a fusible link (240) connected in series with the motor. The fusible link (240) is mounted within a safety shield on a frustoconical partition (60) so that it is exposed to the flow of air leaving the drum. If the laundry being dried should catch fire, the temperature of the air passing the fusible link (240) will rise rapidly. The temperature of the fusible link will therefore also rise, although not so rapidly, because of the limited heat transfer between the air flow and the link (240). However, the fusible link will fairly rapidly reach its cut-out temperature, which might be 100 DEG C, and when this occurs, the motor will be de-energised, so that the burning laundry is no longer continually supplied with fresh air. The cut out device may be connected to control the whole electrical system of the dryer. <IMAGE>
