Title: Improvements in or relating to amplifiers
IPC: G06G7/18
Filed: 1959-11-27
Abstract: 901,787. Electrolytic amplifiers. UNION CARBIDE CORPORATION. Nov. 27, 1959 [Nov. 28, 1958], No. 40322/59. Class 40 (9). An amplifier for varying signals in the frequency range of 1.0 cycle per hour to 0.5 cycle per second comprises an electrolytic cell using a solution of reversible redox system, e.g. 0.5 N potassium iodide and 0.25 N iodine dissolved in a 25% methyl alcohol-water mixture, the electrolytic cell operating as an integrator to which the input signal is applied by way of a differentiating capacitor. As shown in Fig. 1, the cell comprises a sealed glass vessel V having compartments 10, 12 connected by a capillary 14 and containing the electrolyte in three distinct concentration zones. The first zone 16 is of variable concentration and is an " integral " zone between a common anode C and a readout electrode R. A second zone is a " reservoir " zone in the compartment 10 and is of high concentration. An intermediate " dilute " zone 18 lies between the read-out electrode R and a shield electrode S. The basic electrical circuit for operation as an integrator is shown in Fig. 2, a bias potential B2 being applied between the shield electrode S and an input electrode I in the reservoir zone. A bias potential B1 is applied between the read-out and common electrodes R, C, and current flow which is a measure of the solution concentration in the integrating zone 16 is indicated by an ammeter A. In the absence of an input signal the solution concentration in zone 16 remains constant, iodine being reduced to iodide at the read-out electrode R and iodide oxidized to iodine at the common electrode C in the case of a potassium iodide and iodine solution. Increase of the solution concentration is effected by a D.C. signal I applied with the potential shown to the input and common electrodes. For operation as an amplifier the Fig. 3 circuit is used, the varying input signal 36 being applied by way of a differentiating capacitor 34 and the amplified output being obtained across a resistor RL. A D.C. signal I may be applied for a period by a switch 32 to the cell to establish an initial high-concentration solution in the integral zone. The electrodes are preferably composed of platinum gauze or apertured plates, or may be formed of iridium, palladium, rhodium, or alloys with each other or with platinum. Electrodes having a surface of pyrolitic carbon may be used. Other suitable redox systems are ferrocyanide - ferricyanide and cerous-ceric. Suitable solvents include methanol, ethanol, amyl alcohol, butyl alcohol, and water.
