| An oxygen generator is provided in the form of a housing having isolated first and second chambers. Oxygen-generating material is placed in the first chamber and a catalyst for activating the oxygen-generating material is placed in the second chamber. A heat-absorbing hydrated salt is also provided so as to be present during the reaction to absorb the excessive heat released upon the exothermic chemical decomposition of the oxygen-generating material. The salt has an endothermic dehydration reaction temperature below 50.degree. C. A membrane is operationally connected to the reaction chamber to allow the generated oxygen to be expelled from the reaction chamber while retaining the material contents therein. | ||||||
| 163 | Surgical masks | US127069 | 1980-03-04 | US4355637A | 1982-10-26 | Alan Dyer |
| It has already been suggested that chronic exposure of humans to nitrous oxide is a potential health hazard. There is especial concern for those working in the vicinity of a patient to whom nitrous oxide is administered as an anaesthetic. The present invention provides a disposable surgical mask characterized in that a layer comprising particles of a molecular sieve based on silicon dioxide and having an affinity for nitrous oxide is disposed between adjacent layers of the mask. Wearing such a mask reduces personal exposure to nitrous oxide. | ||||||

| 165 | Method for preparing modified graft copolymers of cellulose with monovinyl monomers in the presence of a divinylbenzene modifier | US953341 | 1978-10-23 | US4198326A | 1980-04-15 | Marina O. Lishevskaya; Boris P. Morin; Galina I. Stanchenko; Tatyana A. Vanjushkina; Zakhar A. Rogovin |
| A method for preparing modified graft copolymers of cellulose with monovinyl monomers containing ionic groups or non-ionic groups capable of being converted to ionic ones involving a free-radical polymerization of said monovinyl monomers onto cellulose in the presence of a free-radical type initiator and modification of the resulting graft-copolymers of cellulose with said monovinyl monomers. The processes are performed in one stage in the presence of a modifying agent, that is, divinylbenzene taken in an amount ranging from 1 to 5 mol. % of the monovinyl monomer. The static exchange capacity of the modified graft copolymers of cellulose in the form of cationites is as high as 5 mg-equiv/g. The static exchange capacity of the graft copolymers of cellulose in the form of anionites is as high as 3.5 mg-equiv/g. The degree of swelling in water at a temperature of 20.degree. C. is within the range of from 180 to 200%. The modified graft copolymers of cellulose have a fibrous structure. They are not brittle and are capable of being processed into fabrics, non-woven materials and other textile products (wastes in the textile processing amount to 6-8% by mass of the starting fibres). | ||||||

| A catalyst is provided which is remarkably effective for catalyzing the oxidation of carbon monoxide to carbon dioxide at ambient conditions. This catalyst is prepared by contacting high surface area alumina with a solution of a cobalt compound (e.g., cobalt nitrate), adsorbing the cobalt compound on the alumina, removing the solvent, and thereafter heating the cobalt-treated alumina at a temperature of 400*C to 1,300*C in an oxygenproviding environment.

Gegenstand der Erfindung ist ein Verfahren zur Herstellung von Aktivkohle mit katalytischer Aktivität durch Carbonisierung und nachfolgende Aktivierung kohlenstoffhaltiger organischer Polymere, wobei kohlenstoffhaltige organische Polymere, in die bei deren Herstellung mindestens ein Metallatom und/oder Metallion einpolymerisiert worden ist, einer Carbonisierung und nachfolgenden Aktivierung unterzogen werden, so daß eine mit dem Metallatom und/oder Metallion beladene Aktivkohle resultiert. Auf diese Weise wird eine nachträgliche Beladung mit dem Metall durch aufwendige Imprägnierung erst nach Herstellung der Aktivkohle vermieden. Durch die Ausstattung bereits der Ausgangsmaterialien mit dem Metall läßt sich zudem eine homogenere Beladung erreichen, und dies homogen über alle Arten von Poren (Makro-, Meso- und Mikroporen), so daß die katalytische Aktivität erhöht ist. Zudem ist die Aktivierung beschleunigt. |
