Abstract
824,126. Electrostatic generators; reciprocating generators; rectifying. WOOD, J. F. Aug. 29, 1956 [Aug. 31, 1955], No. 26427/56. Classes 35 and 38 (2). [Also in Group XL (c)] A vibrating A.C. generator consists of a flexible arm 28 actuating a " bender " type piezoelectric crystal 16 or electromagnetic generator, the arm being set in natural oscillation by a pivoted tooth 44 on a manuallyoperated, spring - returned plunger 42. As shown, conductive coatings 22, 24 on a crystal 16 feed a signalling circuit through a rectifier 68, this circuit consisting of an oscillating transistor 14 feeding an aerial 78. If a steady signal is desired a condenser 80 may be inserted. A modification is described in which the crystal comprises two crystals stuck together and feeding separate rectifiers to give effective fullwave rectification. In a further modification, Fig. 4, the crystal is replaced by an electromagnetic generator consisting of a permanentmagnet 154 having poles 156, 158 and a coil 162 surrounding the spring 176. As shown, the generator feeds a radiation measuring circuit comprising a counting chamber 190, audible signal set 196 and voltage regulating tube 208 fed through a voltage multiplier 198, 200, 202, 204. The crystal may be twisted instead of bent.
