Abstract: The present invention relates to a method of removing ink from secondary fiber by contacting a pulp of said secondary fiber with an aqueous medium in the presence of a polymeric material having a glass transition temperature in the range of from about 20.degree. C. to about 70.degree. C. and a substituted polyethylene oxide to agglomerate the ink into discrete masses and separating the agglomerated ink from the pulp-containing aqueous medium.
Abstract: Disclosed are apparatus and method for preventing hypoxic damage, relieving respiratory difficulties and conditioning breathing reflexes in a living human body. More particularly, at least one sensory stimulus is imparted to the body in response to a deviation from at least one adjustable physiological variable followed sequentially by delivery of a respiration restoring gas to the vicinity of the nose and mouth of the body.

Abstract: An electrolyte permeable asbestos diaphragm is prepared by depositing asbestos and a particulate thermoplastic polymeric material from an aqueous slurry including alkali metal hydroxide onto a porous substrate, and heating the deposited asbestos, particulate thermoplastic polymeric material, and alkali metal hydroxide for a period of time, e.g., at least 2 hours, and at temperatures sufficient to react the asbestos and alkali metal hydroxide but temperatures insufficient to melt or sinter the particulate thermoplastic polymeric material, whereby the particulate thermoplastic polymeric material functions to provide permeability for the diaphragm.
Abstract: Disclosed is an adapter assembly for accurately positioning a removable biosensor implanted in the cranium or skull cap. The assembly comprises an outer sleeve member insertable into a hole bored through the skull cap and an inner sleeve member coaxial with the outer sleeve. The sleeve members are constructed so as to permit slidable insertion and removal of the biosensor and to ensure accurate, tilt-free alignment thereof, thus enabling precise, error-free measurement.

Abstract: Disclosed herein is a retainer assembly for applying a membrane to a physiological sensing unit for the transcutaneous determination of the magnitude of physiological quantities, particularly for measuring the partial pressure of gases in blood or the like. The assembly constitutes a preassembly of a membrane, with a clamping ring accommodating the membrane and having an annular recess receiving the rim of the membrane. The clamping ring has a lip in the form of an inwardly protruding annular edge for removably securing the clamping ring together with the membrane to the sensing unit by virtue of the lip resiliently snapping into a peripheral groove of the sensing unit, the lip defining the periphery of the annular recess. A retainer element is provided for temporarily and removably assembling the membrane with the clamping ring prior to assembly with the sensing unit.

Abstract: A liquid permeable diaphragm formed of a major amount polyfluorocarbon fibrils and a minor amount perfluorinated ion exchange material is disclosed. Optionally, the diaphragm may also include inorganic materials such as zirconium oxide, titanium dioxide, aluminum oxide, talc, barium sulfate or potassium titanate, or hydrous inorganic gels such as magnesium oxide gel, zirconium oxide gel, titanium oxide gel or zirconyl phosphate gel. The diaphragm can be prepared by depositing the polyfluorocarbon fibrils and the perfluorinated ion exchange material from a slurry, preferably an aqueous slurry. Optionally, a pore former such as, e.g., polypropylene can be codeposited from the slurry and subsequently removed by heat or dissolution to provide the desired permeability.

Abstract: A method is disclosed for reducing alkali metal chlorate impurities in an aqueous alkali metal hydroxide solution by heating a mixture of the alkali metal hydroxide solution with a hydroxycarboxylic acid or a salt thereof at temperature above about 125.degree. C. and for a period of time sufficient to substantially eliminate the chlorate, the hydroxycarboxylic acid or salt thereof being substantially non-volatile at the heating temperature.
