    Abstract: An hydraulic system comprising a displacement-type hydraulic element in communication with a sealed reservoir tank for receiving hydraulic fluid from and returning hydraulic fluid to the reservoir, and a stabilizer for preventing excessive vacuum and pressure from forming within the reservoir as fluid is moved into and out of the same. The stabilizer is carried within the reservoir tank and has a bellows construction for compensating for change of volume in the reservoir as fluid changes take place therein, and the stabilizer is vented to the atmosphere through a breather system constructed to minimize entrance of dirt and the like within the stabilizer.

    Abstract: A Technetium-99m generator has a matrix having a compound of molybdenum-99 bound into or forming the matrix, the compound of the molybdenum-99 being substantially insoluble in an eluant which can be used in a radiopharmaceutical and the molybdenum compound permitting diffusion of technetium-99m therethrough and elution therefrom. The molybdenum compound can be a monomolybdate, an isopolymolybdate or a heteropolymolybdate and zirconium molybdate is preferred although other cation molybdates may be used. Methods of preparation of the generator include dissolving irradiated molybdenum trioxide in alkaline solution and precipitating the molybdate at a selected pH and packing the precipitate in finely divided form into a column. Alternatively the generator may be formed from a non-radioactive, molybdenum compound and activated later when desired by passing a solution of a compound of molybdenum-99 through the column.

    Abstract: A generator for liquid containing .sup.99m Tc has an adsorbant bed of alumina, zirconia or the like and has associated therewith a quantity of an electron scavenging compound of a rare earth, silver or gold so as to maintain elution efficiency during the working life of the generator. The compound may be a rare earth oxide such as ceric oxide typically present as a coating on alumina particles in an amount of about 0.1% by weight or a compound such as silver chloride present in quantities typically of about 5%. The eluant may be sodium or potassium perchlorate in water.

    Abstract: A method and system for determining organic matter in an aqueous solution including an oxidizing agent are disclosed. The method includes contacting the solution with a semiconductor which is capable of photocatalytically oxidizing the organic matter, illuminating the semiconductor with light of a wavelength or having a spectrum whereby the semiconductor photocatalytically oxidizes the organic matter in the solution to form a photocatalytic by-product(s), and detecting the by-product(s). The system includes a photocatalytic reactor (104) having a semiconductor, which is capable of photocatalytically-oxidizing the organic matter to form a photocatalytic by-product(s), disposed therein so as to contact the solution when disposed in the reactor, an illumination source (103) disposed to illuminate the semiconductor in the reactor wherein the source is capable of emitting light of a wavelength or having a spectrum whereby upon illumination of the semiconductor in contact with the solution the semiconductor photocatalytically-oxidizes the organic matter in the solution, and a device for detecting the by-product(s) (108, 109) operatively associated with or operatively coupled to the reactor.
