Abstract: A dehumidifier includes an elongated body in which a first open ended chamber and a second open ended chamber are defined parallel to each other along the longitudinal direction of the body. A first cover and a second cover are detachably secured to the ends of the body, to cover the open ends of the first and second chambers, respectively. An evaporator is housed in the first chamber. A pipe is disposed in the second chamber, and divides the second chamber into a precooling zone, which corresponds to the internal space of the pipe extending along the axis thereof, and a reheating zone which corresponds to the external space. A path connects the outlet of the precooling zone and the inlet of the first chamber, and is defined between the dehumidifier body and the second cover, for feeding the air from the precooling zone to the first chamber.

Abstract: Apparatus for separating gaseous mixtures comprising a pair of separator vessels each packed with adsorbent material such as silica gel, activated alumina or molecular sieves or absorbent material such as lithium chloride with serving as separating material, wherein a separating cycle during which air containing water vapor or gaseous mixture consisting of two or more different components such as nitrogen and oxygen is fed into one of the separator vessels to remove one or more components from the mixture and a regenerating cycle during which the processed gaseous mixture is partially fed into the other separator vessel to remove the quantity of components previously adsorbed or adsorbed by the separating material present within this separator vessel and thereby to regenerate the separating material are alternately repeated and wherein there are provided regeneration promoting separator vessels for further removal of the components to a lower concentration.

Abstract: The present invention provides (1) an endotoxin detoxifying material comprising a fibrous carrier to which Polymyxin is fixed, (2) an endotoxin detoxifying material comprising a carrier to which Polymyxin and a basic nitrogen atom are fixed, and (3) a method of removing endotoxin from a fluid by contacting the fluid with the endotoxin detoxifying material comprising a carrier to which Polymyxin is fixed.The present invention makes it possible to contact blood with Polymixin directly and safely and gives a new method of therapy endotoxemia or prophylaxis of endotoxemia.
