Title: Electrodialysis apparatus
IPC: B01D61/50
Filed: 1962-02-08
Abstract: <PICT:0943522/C3/1> <PICT:0943522/C3/2> An electrodialysis stack 21, Fig. 1, e.g. for purifying water, is mounted over an aperture 11 in a tank 10, a platinum wire electrode 19 being mounted in the tank and a platinum foil electrode in the stack.  The tank volume is at least twice that of the liquid treatment compartments of the stack and contains e.g. HCl, H2SO4, NaHSO4 or NaHSO3 solution whereby, in operation, formation of harmful precipitates within the stack is prevented.  The liquid level in the tank is maintained by a water supply 12. As shown in Fig. 4, the stack comprises alternately anion and cation permselective membranes 24A, 24K spaced by gaskets 23, 23B, the membranes and gaskets having apertures so arranged that there is parallel flow through concentrating and diluting compartments.  A stream which becomes diluted is supplied at 35 and removed at 48.  A stream which becomes concentrated is supplied at 34, flows through the stack, and then through a tube 49 and over the electrode 46 and out of the stack at 50. Solution from the tank 10 passes through the adjacent stack membrane by electrodialysis or diffusion and is circulated with the concentrating stream.  Gas produced at the electrode in the tank is vented at 18 whereas gas produced at the electrode 46 is carried away by the stream flowing over it.  The electrode 19 may be either a cathode or anode.  If it is an anode and the tank solution is NaHSO3 any Cl2 or O2 liberated will be reduced.  Several stacks may be mounted on a single tank.

Title: Selective anodization of metal films
IPC: C23F1/00
Filed: 1963-02-07
Abstract: <PICT:1031042/C6-C7/1> An anodized pattern on a film of a refractory metal supported on substrate is made by (1) depositing a film of the refractory metal on the substrate on which (2) a layer of aluminium is deposited both by sputtering or vaporizing the metals; the aluminium layer may be deposited through a mask or (3) is photo engraved and etched to remove aluminium in the desired pattern on the underlying refractory metal layer, which together with the remaining aluminium (4) is anodized, and finally (5) the anodized aluminium and underlying refractory metal is etched away, leaving the desired pattern of anodized refractory metal.  Refractory metals specified are Ta, Nb, Ti, W, and Zn, which are applied to ceramic or glass sheet.  Anodizing is effected at 50 V using boric acid-sodium borate solution, or with citric acid solution at 150 V.  Etching is preferably effected in two stages (1) with dilute HCl or NaOH to remove the anodized aluminium layer, and then HF and HNO3 to remove the refractory metal, but the latter mixture may be used to remove both.  Fig. 4 shows substrate 11, tantalum layer 12 of 300 DEG  to 5000 DEG A, aluminium layer 13 of 1000 DEG  to 2500 DEG A, anodized aluminium 15, and tantalum pentoxide layer 16 about 650 DEG A thick. In the final assembly only the layer portion 16 remains with the corresponding underlying area of 12 on the substrate, and is used for the fabrication of printed circuit components e.g. resistor and capacitors.

Abstract: 502,988. Lead titanate; pigments. TITAN CO., Inc. Feb. 22, 1938, No. 5619. Convention date, Feb. 23, 1937. [Classes 1 (iii) and 95] Pigments comprising lead titanate are obtained from an intimate and uniform mixture of a reactive lead compound and a reactive titanium compound other than a titanium ore by heating the mixture to 500-750‹ C. until the lead and titanium compounds have reacted to form lead titanate and then heating for a further period to 750-800‹ C. or higher to develop the pigmentary properties. Heating may be effected in two distinct stages or the mixture may be heated through a range of gradually increasing temperatures, for instance in a rotary furnace. Preferably the mixture does hot contain more than 1 mol. of PbO per mol TiO2, and products containing as little as 5 per cent lead titanate may be obtained, but preferably the final product contains not more than 1 per cent free PbO and not more than 2 per cent free TiO2. By including free or combined sulphuric acid in the initial mixture,. products containing lead sulphate may be obtained ; in this case the amount of lead present should be sufficient to form titanate with the TiO2 and sulphate with the sulphuric acid and the maximum temperature should not exceed 900‹ C. The final pigment may contain 5-25 per cent of lead sulphate, and the sulphuric acid may be provided wholly or in part by using hydrolytically precipitated titanium hydroxide. The initial mixture may be obtained by wet milling with or without dispersing agents followed if necessary by flocculation, by co-precipitation from solution, or by precipitating one component on to the other. The initial mixture should consist of particles having an average maximum width of 2-3 microns and the final product should not contain more than a trace of particles having a maximum width above 5 microns. Inert extenders such as barium or calcium sulphate may be included in the initial mixture. Examples of operation are given. Specification 416,615 is referred to.
