摘要:
A method, and system, to induce remission in diseases characterized by excess production of sTNR and interleukin 2 has been developed. In the most preferred embodiment, the system consists of antibodies to sTNFR1, sTNFR2 and sIL2R immobilized in a column containing a material such as SEPHAROSE™. The patient is connected to a pheresis machine which separates the blood into the plasma and red cells, and the plasma is circulated through the column until the desired reduction in levels of sTNFR1, sTNFR2, and IL2 is achieved, preferably to less than normal levels. In the preferred method, patients are treated three times a week for four weeks. This process can be repeated after a period of time. Clinical studies showed reduction in tumor burden in patients having failed conventional chemotherapy and radiation treatments.
摘要:
The invention relates to a product for transformation of a toxic corrosive or environmentally-noxious product into a non-corrosive or non-noxious residue, comprising at least one amphoteric agent, at least one lipophilic absorbent, at least one hydrophilic absorbent and at least one binary coloured indicator, selected from the group of the following mixtures: Nile blue/alizarin red, alizarin yellow/alizarin red, thymolphthalein/methyl red, phenolphthalein/methyl red and tropaeolin OO/thymol blue and optionally an additive selected from the group comprising charge agents, granulation agents, anti-static agents and mixtures thereof.
摘要:
An additive formulated for blending with bulk absorbent materials to cause the absorbent materials to agglomerate upon the introduction of urine or waste products. The invention also comprises mixtures of the additive with the conventional absorbent materials. The additive itself comprises: a polysaccharide, such as a galactomannan gum; a borate compound for use as a cross-linking agent; a dicarboxylic acid in order to acidify the pH of the additive; and preferably a flow control element such as silica. An additional element may also be added to assist in fixing the additive to the absorbent materials, to control dust during the mixing process, and to improve the flow of the material when poured out of a container by the end user.
摘要:
A synthetic, semi-crystalline, porous inorganic oxide composition containing a reactive organic silane moiety which on the surface of pore walls. The composition is prepared from a poly(oxyalkylene) based surfactant and a hydrolyzable organic silane. The surfactant is preferably a poly (ethylene) oxide, a poly(propylene) oxide polymer or mixtures thereof. The organic silane is preferably mercaptopropylsilane. The compositions are particularly useful as adsorbents, and catalysts.
摘要:
The concentration of a hydrocarbon gas in a gas discharged from a drain port is detected by a break-through gas concentration sensor provided in a discharge pipe connected to the drain port. The entire amount of the hydrocarbon gas discharged from the drain port as a result of breaking-through of an adsorbent layer is collected by a break-through gas collecting means, and the entire amount of the hydrocarbon gas collected by the break-through gas collecting means is detected. Thus, in measuring the adsorbing ability of a canister, the concentration of the hydrocarbon discharged from the canister by the breaking-through can be detected with the passage of time and in a stable manner, whereby a measurement value of an excellent accuracy can be provided by a single measurement.
摘要:
A method is described for the preconditioning of an adsorbent, such as activated carbon, prior to charging the adsorbent into a reaction vessel of a vapor recovery system. The method includes the steps of (1) treating the adsorbent in order to establish in the adsorbent a residual heel of vapor of the type to be subsequently adsorbed in vapor recovery processing and (2) adding the treated and, therefore, preconditioned adsorbent to the reaction vessel of the vapor recovery system. In this way vapor recovery system downtime is significantly reduced.
摘要:
A passive filter for taking up gaseous substances, preferably gaseous smelling substances, from a space, including a porous sorbating, self regenerating material composition, including two material components (A, B), of which a first material component (A) consists of one or more porous materials such as perlite, zeolite, bentonite, silicon dioxide ground to powder or christobalite, and a second material component (B) consists of one or more materials with the capability to take up water molecules directly from the surrounding air, such as silicon dioxide gel, starch or derivatives of cellulose, gypsom, silicates of alkali, aluminum silicate, or fuller's earth. The material components (A, B) are kept joined into a lattice by means of a binder, at which the first material component (A) join with 50-95%, preferably 80-90% (percentage of weight), and the second material component (B) with 5-50%, preferably 10-20% (percentage of weight), in the material composition.
摘要:
A method of modifying the adsorptive characteristics of an adsorptive surface comprising the in situ precipitation of a polyvalent metal salt from a solution in contact with the adsorptive surface; the adsorptive product produced thereby and methods for the removal of impurities from aqueous materials by contact with the adsorptive product.
摘要:
A material for gas separation which consists essentially of (A) a cobalt salt; and (B) amine compound and/or its derivatives containing therein a unit structure to be represented by the following general formula: --NHCH.sub.2 CH.sub.2 CH.sub.2).sub.n [where: n is an integer of 2 or more], wherein the components (A) and (B) are brought into mutual contact to produce the material for gas separation.
摘要:
A solid adsorbent comprising:(a) at least one copper(I) halide, (b) at least one aluminum(III) halide, and (c) polystyrene or its derivatives; or(a) at least one copper(I) halide, (b) at least one aluminum(III) halide, and (c') activated carbon or graphite.This solid adsorbent can effectively adsorb carbon monoxide from a gas mixture containing 1% to 99% by volume of carbon monoxide. Furthermore, the adsorbents comprising components (a), (b) and (c'), or components (a), (b) and (c) prepared by using nonaromatic solvents can effectively adsorb carbon monoxide from a gas mixture containing up to approximately 40,000 ppm of water.
