Abstract

1,086,834. Radio signalling. SIEMENS A.G. March 18, 1966 [March 19, 1965], No. 11897/66. Heading H4L. A mobile station such as a taxi linked by radio with a central station is equipped to send its identity in voice frequency form when a call key is actuated, one frequency being allotted to each digit value, to control a lamp indicator, for example, and in addition this may be followed by a common frequency should an emergency key be actuated as well. This has the effect of operating a buzzer or other alarm. If desired the whole transmission may be repeated at short intervals.
