Title: Method and apparatus for measuring the concentration of dissolved gas in a liquid
Inventor: WATSON REGINALD GORDON HARRY
IPC: G01N27/49
Filed: 1959-11-24
Abstract: 894,370. Determining quantities of fluid mixture constituents. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Nov. 23, 1960 [Nov. 24, 1959], No. 39778/59. Class 37. In a method of measuring the concentration of a dissolved gas in a liquid, applicable to the measurement of oxygen in boiler feed water, a sample of the liquid is combined in an electrolytic cell and agitated, the current passing through the cell due to an E.M.F. applied to the electrodes being proportional to the concentration of the dissolved gas. A suitable plastic cell, Fig. 1, for measuring dissolved oxygen, has a carbon anode 9 and a platinum cathode 10 spaced apart by corrugated and perforated P.V.C., a hollow plastic disc stirrer (not shown) containing two steel members and rotatable by a magnet from outside the cell, and an outlet pipe 8 which permits the addition of electrolyte to the sample liquid to increase its conductivity. The oxygen concentration is deduced from measurements of the cell current with and without stirring of the electrolyte, the cell being calibrated either by the addition of water equilibrated with air, or by discharging a capacitor through the pair of auxiliary platinum electrodes 6. Dissolved hydrogen may be measured by the use of a carbon cathode and platinum anode. If both electrodes are of platinum the cell is sensitive to both oxygen and hydrogen. It is stated as known to measure the concentration of dissolved oxygen in a flowing conductive liquid by measuring the current passing between immersed platinum and cadmium electrodes, due to an applied E.M.F.

Abstract: 1,269,256. Semi-conductor devices. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 12 Aug., 1969 [28 Aug., 1968], No. 40174/69. Heading H1K. A magnetosensitive device comprises a body of semi-conductor material having an emitter region and two ohmic contacts to parts of the body spaced from the emitter region. The current flows from the emitter region to the two ohmic contacts and when the device is subjected to a magnetic field the current carriers are deflected to steer the current away from one of the contacts towards the other. As shown, Fig. 4, an N<SP>+</SP> type emitter region 2 is formed in a P-type substrate 1 by diffusion using an SiO 2  mask. A contact 5 is applied to the emitter region and two symmetrically situated ohmic contacts 3, 4 are applied to the substrate 1. The two ohmic contacts 3, 4 are connected to resistors R1, R2 to form a bridge circuit which is used to measure the magnitude and direction of the magnetic field applied to the device. The two resistors may be integrated into the substrate by forming two N<SP>+</SP> type regions in the lower face which are connected to the ohmic contacts on the substrate by conductive tracks overlying an insulating layer, Fig. 5 (not shown). In a modification the ohmic contacts are applied to the same face of the substrate as the contact to the emitter region, Fig. 6 (not shown), and the resistive regions can also be integrated into this face of the substrate, Fig. 7 (not shown).

A photographic camera comprises means for positioning a filter in two predetermined discrete positions, one of said positions being wholly in the path between the subject and the photo-sensitive medium, and the positions being wholly out of the path, said means comprising at least two photoelectric cells sensitive to different wavelengths of light which alter the position of the filter accordingly as the ratio of the currents passing through the cells is above or below a predetermined value. In the embodiment shown in Fig. 1 the photo-electric cells 1, 2, 3 and 4 are arranged in a bridge circuit with a control amplifier 6 which triggers the movement of the filter according to the direction of the current passing therethrough. The point at which the filter changes over may be regulated by a bridge circuit containing a potentiometer or a dual coil actuator. The photo-cells may form a photo-conductive cell bridge composed of four photo-conductors all on the same surface each of the individual cells being in the form of an interdigital array of conductors sandwiching a photoconductive material, one conductor of each array being common with a conductor of another cell. Other bridge circuits involving transistor amplifiers are described.

Abstract: 1430539 Electrolytic capacitors SIEMENS AG 1 Oct 1974 [5 Dec 1973] 42471/74 Heading HIM In the manufacture of electrolytic capacitors, a secondary formation is carried out by subjecting the capacitors individually to the action of a constant current of magnitude such that the secondary formation voltage, of value between the working voltage and the primary formation voltage, is reached in at most 10 seconds. The capacitor may comprise anode foil strips cut from an anodized sheet of valve metal, e.g. aluminium, wound into a roll with cathode foil and a paper separator impregnated with electrolyte. The constant current is obtained by regulating the current from a stabilized voltage source. Secondary formation may be carried out before or after the rod is placed in a housing but prior to sealing. The capacitors may be aged at, e.g., 85‹ C. for 0À5 to 2 hours by applying a voltage between the working voltage and the secondary formation voltage.
