Abstract: 934,722. Measuring instruments. E. R. JACKSON. Jan. 16, 1962 [Jan. 25, 1961], No. 2876/61. Class 37. An electrical voltage signal derived, e.g. from a rotor unbalance test machine is applied to the input A B of an attenuator whose output C D is fed to a rotor 17 calibrated in units of dynamic unbalance; either directly or from an attenuating tap on shunt potentiometer P1 under control of relay contacts CR1. The output at C D is also rectified and applied over tapped potentiometer P 2  to transistor T which conducts at a predetermined signal level to energize relay MR which operates relay CR to hold over contacts CR2 and illuminates pilot lamp P L, whereby attenuation is introduced to the input signal. P2 is preset so that the relays operate when the deflection of meter 17 exceeds full scale and P 1  is preset, e.g. to halve the input signal. Additional contacts of relay C R may alternatively expose or illuminate a meter scale appropriate to the inserted attenuation. Relay CR may be released at will by interrupting the hold circuit, and further additional stages of attenuation with appropriate meter scales may be similarly introduced.

Title: Apparatus for effecting chemical analyses by means of dropping mercury electrodes
IPC: G01N27/48
Filed: 1946-01-31
Abstract: <PICT:0613133/III/1> In an apparatus for effecting chemical analysis by comparison by means dropping mercury electrodes in which a regulatable continuous voltage and an alternating voltage are simultaneously applied to two electrodes, one of which is a dropping mercury electrode, the resulting alternating current is amplified, if necessary its voltage being first adjusted by means of a transformer, and its R.M.S. value measured for example by means of a rectifier followed by a moving coil milliampere meter.  The frequency of the alternating voltage may be between 20 and 300 periods per second, and the alternating voltage may vary between 10 and 200 millivolts.  In one embodiment the solution to be examined is contained in a receiver s having an electrode a and a dropping mercury electrode c between which is applied a continuous voltage from a potentiometer p.  An alternating voltage from oscillator o is superposed on the continuous voltage by means of a transformer T1.  The alternating current traversing the electrodes passes into the primary of a transformer T2, inducing in the secondary a current which is amplified at A and measured at M.  In another embodiment the necessity of measuring the absolute value of the alternating current is eliminated by applying a counter-voltage arrangement to the alternating current, and this is effected by carrying the cathode of a rectifying valve to a positive potential by means of a potentiometer.
