摘要： Accumulations of tramp oils are removed from oil-in-water emulsions utilized as cleaners, lubricants and coolants by introducing into the emulsion a small but effective amount of a high molecular weight, water-soluble anionic polymer and heating the treated emulsion at an elevated temperature whereby the tramp oils are coalesced and floated to the surface of the emulsion. The essentially continuous but distinct tramp oil and emulsion phases are then readily separated.

摘要： METAL OXIDE DEHYDROGENATING CATALYSTS HAVING AN ELECTRICALLY CONDUCTING, DISCONTINUOUS AMOUNT OF CERTAIN SPECIFIC METALS INCORPORATED EITHER THROUGH THE BULK OF THE CATALYST OR DISTRIBUTED ON ITS SURFACES PROVIDE COMPARATIVELY HGH ELECTRICAL CONDUCTIVITY, AND CAN BE MORE UNIFORMLY HEATED BY USE OF AN ELECTRICAL CURRENT THAN SIMILAR CATALYSTS HAVING NO FREE METAL PRESENT. THE METAL-CONTAINING OR METAL-COATED CATALYSTS CAN COMPRISES THE ENTIRE MASS OF CATALYST IN A REACTOR, OR SUCH CATALYST CAN BE PLACED ADJACENT TO THE ELECTRODES AND IN INTIMATE CONTACT WITH CATALYST CONTAINING NO METAL TO PROMOTE MORE UNIFORM PASSAGE OF ELECTRICAL CURRENT THROUGH A CATALYST BED. THE NOVEL METHOD COMPRISES THE USE OF THE CATALYST HAVING METAL PARTICLES DISCONTINUOUSLY DISTRIBUTEED THROUGHOUT ITS BULK AS THE SOLE CATALYST, OR AS PART OF THE CATALYST BED IN CONTACT WITH ELECTRODES, ADMIXED WITH CATALYST CONTAINING NO METAL, TO DEHYDROGENATE HYDROCARBONS, WHILE PASSING AN ELECTRICAL CURRENT THROUGH THE CATALYST BED TO MAINTAIN DESIRED TEMPERATURE LEVELS.

摘要： A system for carrying out hemodialysis with high flux membranes without incurring the risk of excessive ultrafiltration rates or reverse ultrafiltration is disclosed. The transmembrane pressure differential is held constant, despite changes in pressure on the blood side of the membrane. The actual differential is sensed, compared to a desired positive magnitude and the pumping rate of a positive displacement, discharge pump adjusted to alter the proportion of the dialysate which passes through a restricted shunt path around the pump, thereby altering the back-pressure on the dialysate side of the membrane until the differential has the desired magnitude.

摘要： A device for detecting and measuring fluctuations on a continuous basis and at most any concentration level, in a flowing gas stream, of a reactive component such as, oxygen, chlorine, bromine, iodine, sulfur dioxide, sulfur trioxide, hydrogen sulfide, carbon monoxide and compatible mixtures thereof utilizes as the detecting element a concentration cell made from two electrodes formed of substantially identical metal, a reference electrode and a sample electrode, at least the latter being foraminous in nature, an aqueous electrolyte containing a mobile soluble ion, the electrolyte contacting substantial areas of both electrodes, a substantially constant atmosphere or a lack of any atmosphere around the reference electrode, an enclosed zone around the sample electrode and means for bringing the gas stream to and from the enclosed zone. No impressed voltage or amperage is applied. The small potential difference across the electrodes generated by chemical equilibrium shifts in the concentration cell caused by fluctuations in the gas stream composition are measured by a sensitive Wheatstone bridge or a microammeter or other sensitive detection means.
