A treatment apparatus of the present invention includes a hermetic door 115b and a retort 115c as an interface for taking out a gaseous emission containing vaporized substances from an object to be treated which is being heated in a reduced pressure state in a second hermetic chamber 103 while maintaining conditions in the second hermetic chamber. When the retort 115c is inserted into a first opening 103b of the second hermetic chamber, the hermetic door 115b in an open state is shielded from th...

Device for treating blood comprising an elongated tubular member of semi-permeable membrane defining a blood flow path, a pair of membrane supports extending adjacent the path on opposite sides of the membrane, each support having a series of protuberances extending longitudinally of the support and spaced across the width of the support, the protuberances of one support being spaced between and overlapping the protuberances of the other support to cause the tubular member to assume a zig-zag fo...

An apparatus for treating or coating flexible sheet or film-like materials with a fluid. The material to be treated and the treating fluid move past an elongated and grooved plate member with the fluid between the material and the plate member. The grooves are closely spaced and extend in a direction normal to the path of the fluid.

Polybutadienes are treated with titanium tetrachloride and molecular oxygen to form modified polybutadiene products having substantially higher Mooney viscosities, characterized by a reduced tendency to cold flow.

The flavor of tobacco smoke is influenced by the addition of a substance of the following formula in which R represents --CH.sub.2 --CHO, --(CH.sub.2).sub.2 --CHO, --CO--CHO, --CH.sub.2 --CO--CHO, --CH.sub.2 OH, --(CH.sub.2).sub.2 OH, --OHOH--CH.sub.2 --CH.sub.3, --CO--(CH.sub.2).sub.3 OH, --CO--CHOH--CH.sub.3, or --CO--COO--C.sub.2 H.sub.5. The added compound comprises approximately 0.001 percent to 1.0 percent by weight of the tobacco composition.

Hydrocarbon catalytic reactions (including isomerisation, cyclisation, aromatisation, disproportionation, alkylation, de-alkylation, reforming, hydrocracking) are effected over a catalyst comprising a crystalline solid solution of two or more irreducible compounds differing in the valency of their cations and/or their anions. The catalysts may be made by heating together the components of the crystalline solid solution or compounds thermally decomposable thereto. Some of the catalysts contain on...

The invention relates to a process for the restoration and prevention of gastrointestinal injuries, which comprises treating a patient with an effective dose of racemic or optically active 1,6-dimethyl-4-oxo-1,6,7,8,9,9a-hexahydro-4H-pyrimido[1,2-a]pyrimidine-3-c arboxamide.

Treating compositions containing mutual solvents suitable for forming and maintaining single-phase aqueous fluid treating compositions containing very high concentrations of acids and/or chelating agents are described. Methods of use of these treating compositions for dissolving and removing scale and formation matrix material in oil-field treatments such as stimulation and remediation are given.

Tobacco is treated with a compound of the following general formula ##SPC1## In which R.sub.1 =--h, --ch.sub.3, or --C.sub.2 H.sub.5, and R.sub.2 =--h, --ch.sub.3, or --C.sub.2 H.sub.5. The tobacco smoke is thus aromatized in a controlled manner and an intensified total flavor impression is obtained.

Apparatus for providing emergency treatment to a burns patient. The apparatus includes a bag (11) having a wall (15) which defines a space (16) for receiving the burns patient so as to provide a protective environment about the patient. The bag (11) comprises a first portion (21) constructed of flexible waterproof material and a second portion (22) constructed of fluid permeable material. The second portion is so arranged as to be upwardly facing when the bag is in use and is detachable from the...
