A transcutaneous blood oxygen measuring device is disclosed for the noninvasive measurement of oxygen partial pressure in arterial blood which includes a cathode surrounded by an anode held together by an insulating plastic in an electrode part, a heating portion to heat the skin of a subject to which the device is applied and to receive the electrodes plus an electrolyte. The heating portion has an opening to indirectly expose the electrodes, via an electrolyte and associated membrane, to the subject's skin surface. Adjacent the working surfaces of each electrode an electrolyte is provided, retained by an oxygen permeable membrane which, in turn, is brought into contact with the subject's skin. The working face of one electrode, typically the cathode, is extended beyond the plane of the working face of the other electrode; the opening in the heater is smoothly rounded and the cathode plus tapered hole, both having approximately the same cross-sectional area, are placed in close proximity with each other.

A method of disposing of an oil containing emulsified waste water, for example, resulting from metal working processes, which comprises: (a) separating the oil and water present in the oil containing emulsified waste water while maintaining the state of the emulsion, thereby concentrating the oil without breaking the emulsion; (b) mixing the concentrate thus obtained at least with solid material filtered from the oil containing emulsified waste water during metal working, said concentrate being in a homogeneous, stable slurry state due to the action of a surfactant even when mixed with the solid material which contains water, unless said concentrate is dried; (c) subjecting the resulting homogeneous, stable mixture to combustion.
