Abstract
1476235 Piezoelectric igniters BRAUN AG 14 May 1974 [14 May 1973] 01327/77 Divided out of 1476232 Heading H2A A piezoelectric igniter has an impact mechanism comprising a hammer having a lead insert. In the arrangement shown, the hammer comprises a cup-shaped iron shell 110 and a lead core 109, and is normally retained in contact with two pole plates 117 attached to a fixed permanent magnet 116, but if a cap 114 is depressed a spring 119 releases the hammer from the magnetic retaining system 117/116 and drives the hammer onto a plate 108 of a transducer 103. The hammer may comprise a deepdrawn sheet iron cup (121) with a lead core lining (123) as in Fig. 2 (not shown), or it may include a permanent magnet (126) as in Fig. 3 (not shown). In the latter case, the hammer contains a lead ring (127) and a shell (110), and is normally held at rest contacting a fixed iron core (124). The housings are of plastics and may have arched bottoms (as 102, Fig. 3) to provide flexibility in the support for the transducers.
