Abstract: VOLTAGE SURGE PROTECTOR            Abstract of the Disclosure Electrical equipment, such as telephone station apparatus, exposed to occasional, destructively high, voltage surges (e.g., lightning strikes), is protected by a device placed in parallel with the equipment, including two metal electrodes and an insulating housing.          The electrodes define a fixed narrow spark gap which breaks  down (arcs over) to short the voltage surge to ground.  The width of the spark gap is critical, since it determines the protective breakdown voltage.  In the disclosed devices the gap is closely defined although tolerances on the piece parts from which the device is made may be loose.  At least one electrode consists of a flanged support member soldered to an electrode cap.  The piece parts are assembled with the electrode faces in contact and raised to the soldering temperature.  The gap forms as the temperature is reduced from the liquidus temperature of the soldering alloy to ambient temperature because of differential contraction between the insulator material and the metal parts.

Abstract: METHOD OF MANUFACTURING A SLIP CAST ARTICLE                 ABSTRACT OF THE DISCLOSURE         A method of forming a slip cast article is disclosed.  The slip cast article is formed in a casting volume of a forming mold which has a portion  thereof formed of a dissolvable organic material which has binder properties.  A casting slip is cast into the casting volume.          The vehicle of the casting slip is drawn off to a level which provides a consolidated casting in the casting volume containing sufficient vehicle that the casting is resistant to shrinkage.  The consolidated casting and the organic mold portion are placed in a solvent for the mold portion so that it may be dissolved.  The solvent for the mold portion is one which is miscible with the vehicle of the casting slip.  The consolidated casting is maintained in the solvent after the organic mold portion has been dissolved so that the dissolved organic material previously forming the mold portion may penetrate into the consolidated casting.  The consolidated casting is removed from the solvent and dried so that the organic material which penetrated into the casting will remain behind in the porous structure of the casting to lend strength thereto as a binder material.

Abstract: Abstract Process for the manufacture of concentrated formulations which are in the form of free-flowing, low-dust powders or granules and are easily dispersible in aqueous and/or organic media, starting from active ingredients which are sparingly soluble or insoluble in water The active ingredients, for example pigments, dye-stuffs, dyestuff intermediates, optical brighteners, add-itives for plastics, textile auxiliaries, insecticides, herbicides, pharmaceuticals and cosmetics, are comminuted mechanically and/or chemically in an aqueous medium in the presence of a grinding auxiliary until a mean particle size of less than 5 µm has been reached.      The grinding aux-iliary is a salt, present in the dissolved form, of an acid resin        The mechanical comminution may be effected by, for example, wet grinding by means of sand, balls or mills Chemical comminution may be effected by, for example, re-precipitation.      During or after the comminution, at least one organic solvent which has a limited solubility of at least 1% in the aqueous medium, for example in pure or electrolyte-containing water, and which forms a two-phase system with the aqueous medium, is added.      The resulting two-phase system is treated with at least one sparingly water-soluble or insoluble, high molecular carrier, whilst undergoing turbulent mixing.       The volume of the organ-ic phase, which now contains the carrier or carriers and active ingredient or ingredients, is then reduced, by adding further water, to the point that the resulting particles of the formulation can easily be separated off.     Finally, the particles are separated off, rinsed with water and dried if appropriate.

Granted: 1981-12-08
Abstract: Abstract of the Disclosure:            In a polarographic cell of the type which avoids depletion of the species being measured in the sample, the fouling of the membrane covering of the cell is detected by utilizing an electrode which can be substituted for that electrode from which the species being measured is electrochemically generated.  That electrode is spaced remotely from the closely spaced anode  and cathode so that when it is substituted depletion of the species being measured occurs outside the membrane.  By comparing the current output from the cell when it is operating in its normal mode with the output when it is operating with the substitute electrode, as by dividing one value by the other, the degree of fouling of the membrane covering the cell is determined.
