Abstract
463,416. Detecting approach of overtaking vehicles. BOSCH AKT.-GES., R. Sept. 26, 1935, No. 26598. Convention date, Oct. 10, 1934. [Class 118 (ii)] In apparatus for detecting approach of overtaking vehicles, a signal is given only if the sound signal from the overtaking vehicle is given for more than a predetermined time. As shown in the Figure, when sound is picked up by microphone 5 the coil 14 of thermal device 15 is energized, and if the sound is received for more than a predetermined time the contacts 12 close to operate signal 9. In other embodiments described the operation of the signal 9 is delayed by a dashpot or the like on a relay armature or by a chain of slowto-release relays. The signal 9 may remain operated until released by a push-button switch, which may also give a " pass " signal to the overtaking driver.
