Abstract: A deodorizing apparatus adapted to be placed in an enclosure to deodorize the bad smelling components of the foul air within the enclosure. The body has an interior free space and a ozone-decomposing layer. Ozone is generated within the free space and flows in contact with the layer so that it is decomposed before it can leave the body. The ozone is formed either by silent (corona) discharge or by ultraviolet radiation in the free space, and the energy supplied is sufficient to cause the ozone to flow outwardly into contact with the layer and to draw in foul air through the layer so that the decomposing ozone effectively deodorizes by oxidation the bad smelling components. The flow through the device is sufficient to deodorize the entire enclosure.

Abstract: The invention relates to an ammonium plutonate uranate, its preparation process and its use for producing the mixed oxide (U,Pu)O.sub.2.The ammonium plutonate uranate of formula [Cu,Pu)O.sub.3 ].sub.2 [NH.sub.3 ].sub.x [H.sub.2 O].sub.y in which x and y have a value from 0 to 5 with x+y=5, is prepared by neutralization with ammonia of an aqueous solution of uranium VI and plutonium VI salts, e.g. uranyl and plutonyl nitrates. This solution can be prepared by oxidizing a solution of plutonium IV and uranyl nitrate. By calcining under a reducing atmosphere the ammonium plutonate uranate precipitate formed, a mixed oxide (U,Pu)O.sub.2 is obtained having a solubility in 11N HN O.sub.3 without fluoride of at least 99.9%.

Abstract: Polysaccharides are at least partially hydrolyzed by contact with a composition containing urea, sulfuric acid, and water in which the urea/sulfuric acid molar ratio is less than 2. Such proportions of urea and sulfuric acid assure the presence of the monourea adduct of sulfuric acid. The polysaccharide can be hydrolyzed to an extent sufficient only to hydrate the polysaccharide to produce a hydrated polysaccharide such as hydrated cellulose, or it can be completely hydrolyzed to its constituent monosaccharides. Thus, cellulose can be converted to glucose.

Abstract: Compositions of matter and methods of preparation are described for water and air stable, square planar transition metal double-complex salts which contain isonitrile ligands derivatized with long chain aliphatic groups. These salts are composed of two metal-containing complex ions: the cation is a tetrakis isonitrile metal ion and the anion is a tetrahalometallate or tetracyanometallate. These double-complex salts exhibit the novel property of thermochromism and are useful as temperature indicators and in imaging applications.

Abstract: A device for enriching a fluid with ozone includes an inner tubular member arranged within an outer tubular member and defining a separate flow path for a fluid within the inner tubular member and another one for a fluid between the inner and outer tubular members. An electrode which has a high voltage regulation and a coil portion which extends through the inner tubular member forms a grounding electrode. A fluid such as air which is to be enriched with ozone is passed either through the inner tubular member or the space between the two tubular members and a cooling fluid is passed in the other tubular member. The inner tubular member is made of an ultraviolet penetrable and heat resistant material such as quartz glass.

Abstract: The present invention provides a process for producing a uranium oxide by dissolving a yellow cake in sulfuric acid or hydrochloric acid, bringing the obtained solution into contact with a chelating resin of diaminocarboxylic acid type and subjecting the product to neutralizing precipitation followed by heat treatment. By the contact of the solution with the chelating resin, iron, copper, molybdenum and vanadium among the metallic impurities are removed and in the subsequent neutralizing precipitation step, other metallic impurities such as aluminum, calcium, magnesium, sodium and potassium are removed. This process can easily produce uranium oxide having a high purity using a simple apparatus.

Abstract: A rotary ozonizer includes a drive motor for driving a rotor and an air compressor. The rotor is housed in a cylindrical body serving as an stationary electrode. The rotor is secured to a rotor shaft extending through the cylindrical body and rotating upon rotation of the motor through an insulating joint. The rotor serves as a rotary electrode, and provides an electrical discharge spaced relative to the cylindrical body. Electrical power supply portions are connected to the rotor and to the stationary electrode, and end plates are provided to cover open ends of the cylindrical body. The end plates rotatably support the rotor shaft. The motor, the insulating joint, the cylindrical body and the compressor are aligned coaxially in one of the embodiments of the present invention.

Such targeting polypeptides can be used for, example, in the location of tumours and abscesses and other inflammatory conditions and in the monitoring of tissue transplants for possible rejection.

Abstract: Silicon carbide particles are produced by reacting a gaseous silicon compound or granular silicon with a carbon compound at a high temperature. In the reaction, the amount of free carbon content in the resultant silicon carbide particles can be controlled by monitoring the amount of unsaturated hydrocarbon such as acetylene, as a by-product. Moreover, silicon carbide particles can contain boron dispersed uniformly in the particles by a two step process comprising first reacting a silicon source and a boron source without a carbon source in a first reaction zone, to form boron-containing silicon particles, and second, reacting the resultant particles with a carbon source in a second reaction zone.
