Abstract:
Un dispositivo de fraccionamiento para separar solutos en un liquido bruto mediante una membrana, que comprende 1) una parte de suministro (2b) para cargar el liquido bruto; 2) una parte de filtracion con una membrana (5a; 5b; 5c) para filtrar algo de los solutos en el liquido bruto enviado desde la parte de suministro; 3) una parte de concentracion (5d) para concentrar el filtrado procedente de la parte de filtracion; 4) una parte de recuperacion (10) para recuperar la solucion concentrada obtenida en la parte de concentracion; 5) una bomba de flujo para el envio de una fase movil; en el que la bomba de flujo es una bomba de tubo provista de un rotor giratorio y de un rodillo (9) instalado de manera giratoria en la circunferencia exterior del rotor; caracterizado por que la parte de suministro, la parte de filtracion, la parte de concentracion, la parte de recuperacion y un canal de flujo que conecta las partes respectivas, forman un circuito cerrado y estan ensamblados en un cartucho desechable (14) en el que al menos las porciones de los canales de flujo estan expuestas a la pared exterior del cartucho desde el exterior del cartucho, y por que el cartucho se puede separar del rodillo de la bomba de flujo y esta dispuesto de manera que una parte de la pared exterior del cartucho funciona como un miembro de compresion mediante el acoplamiento de la bomba de rodillos para comprimir las porciones expuestas de los canales de flujo cuando el rodillo se hace girar para hacer circular los liquidos en las partes respectivas del cartucho.
Abstract:
It is an object of the present invention to provide a separation membrane in which a film-forming solution can be prevented from reaching a rear surface of a porous support in a step of forming a film, the adhesion between a functional film for separation and the porous support is high, and the thickness can be reduced. In the present invention, the separation membrane includes a porous support having a rough rear surface and a'functional film for separation, and the functional film is disposed on a front surface of the porous support and extends into the porous support.

Abstract:
A bobbin holder (1) of the present invention has loosely fitted between a cylindrical bobbin (23) and a rotating cylinder (2) into which the bobbin is inserted thin elastic rings (3a to h) each comprising a ring-like spring member (30), a pair of rigid rings (38) fixed to the sides of the spring member (30) and a rubber member (39) provided between the pair of rigid rings and on inner and outer circumferences of the spring member. The rigid rings (38) are pressed from the sides of the elastic rings, respectively, the ring-like spring member (30) is deformed radially outwardly so as to increase the diameter thereof, and the rubber member (39) is tightly secured to the internal circumferential surface of the bobbin (23) to thereby be held in place. In this case, in the above bobbin holder, a mode may be possible which has a shape in which the difference δ between the outside diameter Ds of the rotating cylinder and the inside diameter Db of the bobbin is less than 10 mm and the thickness t at the end of the rotating cylinder is smaller than the thickness in the vicinity of a portion where the rotating cylinder is in engagement with a driving shaft. It is possible to realize high-speed winding up in a state in which a bobbin is strongly held when the bobbin holder (1) constructed as described above comprises a wind-up gear in which a linear body such as thread and steel wire, synthetic resin film, fabric sheet and paper are wound up around the bobbin (23).
