Title: Amplifier circuits

Filed: 1975-07-30
Abstract: 1517157 Transistor amplifiers GV PLANER Ltd 30 July 1975 [3 Aug 1974] 34314/74 Heading H3T An amplifier circuit for providing, with an input of one polarity an output related to the input, and with an input of the opposite polarity a reference signal output, for use e.g. with a strain gauge bridge, comprises amplifiers 6, 8 and 9, arranged as shown so that 9 is in a negative feedback path of 8, which path includes a unidirectional conductor 10 poled so that the feedback is effective only with inputs of the said opposite polarity to maintain the output of amplifier 8 at reference potential. An accelerometer comprises a strain gauge bridge I the arms 2, 3 of which are connected to the body under test, the other arms being connected to a rigid mounting. Amplifier 6 connects the bridge output to the input of amplifier 8 via a capacitor 7, the input to 8 being earthed at switch-on by transistor 11 which turns off as a capacitor connected in its base circuit charges up. The bridge resistors 2-5 are chosen so that with no acceleration the output of 6 is negative, and any negative signal into the input of 8 produces a negative input to feedback amplifier 9, resulting in a positive signal applied to diode 10, substantially cancelling out the input from 6, and holding the output of 8 near zero. When the strain gauge 1 is subjected to an acceleration greater than a preset value the output of 6 becomes positive and the self-zeroing action due to 9, 10 becomes ineffective. Integrating circuits 12, 14 provide velocity and distance outputs respectively. Transistors 16, 17 short circuit the integrators until a positive signal from 8 actuates Schmitt trigger 18 and amplifier 19 to turn off 16 and 17 respectively.

Nov. 15, 1930, No. 34477. Convention date, Nov. 15, 1929. [Class 38 (v).] In gas-blast circuit-breakers having a conduit c for conducting the arc-suppressing gas from the stationary contact b, the conduit and contact being mounted together by means of an insulator d, the formation of metal or metallic-oxide coatings on the insulator is prevented by forcing over its surface a stream of gas independent of that flowing over the insulator due to the blast at break. In the construction shown, the interior surface of the insulator is subjected to a stream of gas supplied to an annulus e in the fixed contact b and escaping through openings f. The outer surface is exposed to a flow of gas from passages i communicating with an annulus h in a ring g between the insulator and the conduit. The gas may be obtained from the source that supplies the main gas blast and may be supplied at the moment of interruption.
