Patent SE-459396-B (SE)
Title: Filter fitted against gel bed in chromatographic sepn. column
Inventor: BELLQVIST P
IPC: B01D15/08
Filed: 1988-03-21
Abstract: The chromatographic sepn. column is filled to a specific height with a bed of sepn. gel. Against the gel bed a piston is maintained pressed by a shaft. This shaft is locked against axial displacement in a column end piece. There is a centre hole through the shaft and piston through which eluent and samples for sepn. are pumped. To protect the gel bed and also hold it in position in the column, a filter is fitted on the piston end locating against the bed. The filter comprises a woven fabric fastened in a ring, which in turn is clamped via an inner circular flange in a corresp. track in the piston. The filter fabric has a very small mesh width, e.g., less than 20 micrometres, so that the plastic pulp, e.g., polypropene, used for moulding the ring cannot penetrate through the fabric and thereby moulds the fabric firmly in the ring. The fabric is of material incompatible with that of the ring plastic pulp, e.g., polytetrafluoroethylene, and cannot be fastened in the ring by conventional adhesion or welding.

Granted: 1996-02-20
Abstract: Uno dei lavori pesanti per l'operaio Conciario é agganciare il pellame lavorato e sganciarlo quando é asciutto sotto una catenaria per delle ore. Con il presente ritrovato si é voluto sostituire il lavoro massacrante dell'operaio con un piccolo automatismo, la pinza a rotelle dentate con comando automatico dello sganciamento pelli, che oltre ad agevolare la mano d'opera, snellisce notevolmente la produzione giornaliera.L'inserimento della pelle nella pinza bloccaggio avviene automaticamente con una semplice macchina particolare (ausiliaria), la quale prende le pelli e le infila tra le rotelline dentate della pinza. Le rotelline, con la sola caduta per inerzia, bloccano la pelle tra le pareti dentate.L'agganciamento é ancora più semplice, alla fine della catenaria vi saranno due cammes ai sue lati della pinza, la quale passandoci sopra con le due prolunghe del perno centrale solleverà le rotelline sbloccando così il pellame.
