Abstract

1,219,499. Direction responsive switches. INTERNATIONAL COMPUTERS Ltd. 17 Sept., 1969 [31 Oct., 1968], No. 51699/68. Heading H1N. [Also in Division G1] A direction responsive switch comprises a pendulum 22 pivoted at 26 and having a projection 27 engaging a toothed wheel 32 and further projections 23, 25 which deflect either of resiliently mounted contacts 19, 20 depending on the direction of rotation of the wheel. The deflected contact then springs back so as to make a momentary contact with fixed contact 17 or 18, this being noted by a data recorder. The rotation of the wheel is caused by the rise or fall of a liquid which is detected and recorded by means of the float and subsequent system of Fig. 1 (not shown) which includes the above mentioned switch.
