  • Patent number: 4056660
    Abstract: A rechargeable nickel-cadmium cell including a plurality of alternately arranged positive and negative electrodes. An oxygen sensing electrode is provided between one of the positive and one of the negative electrodes and connected to the negative terminal of the cell through an external resistor. The sensing electrode includes a suitable substrate on which cadmium is caused to be deposited, the cadmium, in the preferred form of the invention, being deposited in an amount approximately 20% of that employed in making the negative electrodes of the cell. Thereafter, the electrode is treated with silver and also, in one form of the invention, with a hydrophobic fluorocarbon polymer, such as polytetrafluoroethylene, these materials being dispersed in intimate contact with the relatively porous cadmium deposit.

  • Patent number: 4034066
    Abstract: Improvements are provided in reaction vessel construction used in the growth of diamond by the process disclosed in U.S. Pat. No. 3,297,407 -- Wentorf, Jr. In assembly of the reaction vessel of this invention, the plug of catalyst-solvent material is disposed between the source of carbon and the diamond seed material as in the Wentorf, Jr. patent and, in addition, the diamond seed material is separated from the catalyst-solvent plug by means for isolating the diamond seed material from the catalyst-solvent material until after the latter has become saturated with carbon from the source of carbon. In addition, preferably the under surface of the plug of catalyst-solvent metal is covered with means for suppressing diamond nucleation. The nucleation suppressing means is usually in the form of a disc and may completely cover the underside of the catalyst-solvent plug or may have a hole therethrough in juxtaposition to the diamond seed/isolating means combination(s).

  • Patent number: 4029635
    Abstract: A process for forming a silicone resin useful for making mica laminates comprising adding a mixture of organotrihalosilanes and dimethyldihalosilanes dissolved in a water immiscible organic solvent to a heterogeneous hydrolysis mixture composed of a water immiscible organic solvent and an alcohol and separating the solvent resin layer where the organic groups on said trihalosilane are methyl and phenyl with the mole percent concentration of the methyl groups to phenyl groups varying from 30 to 70 mole percent. The hydrolysis addition is generally carried out at a temperature of 25.degree. C to 80.degree. C. The resin produced by this process has an organo and methyl to Si ratio varying from 1.01 to 1 to 1.1 to 1. The alkoxy content is less than 6% by weight and, preferably, varies from 2 to 4% by weight and the silanol content is generally less than 6% by weight and preferably varies from 2 to 4% by weight.
