Abstract

1310439 Electromedical apparatus WEYRAD (ELECTRONICS) Ltd 13 Aug 1971 [13 Aug 1970] 39034/70 Heading G1N In a pressure-sensitive endoradiosonde, the armature 20 which affects the inductance of a coil 14 arranged in an oscillator circuit 16, Figs.3 and 4, (not shown), is mounted on a diaphragm 22 arranged in a support 23 which can be adjustably screwed into and out of the body 2 so as to vary the oscillator frequency range for a given pressure range. The oscillator circuit is arranged on a circuit board 15 and the body 2 encloses a storage cell 4 which may be removed and replaced by removing a clip on cap 3 by pulling a string 5.
