Title: Isolating enclosures
IPC: A61G10/00
Filed: 1980-03-18
Abstract: In method of removing an article from an enclosure providing an environment isolated from the ambient environment, particularly applicable in removing infected hospital materials from isolator enclosure members for isolating human patients with acute infectious diseases, spread of infection is prevented and the integrity of the isolation is maintained by the provision of a closed closure bag. In one arrangement of the invention a disposal bag 21 sealed around a port 25 contains a closure bag having a rigid hoop across the disposal bag 21. A heat sealer cuts and seals around the hoop leaving part of closure bag closing the disposal bag 21 and part of bag closing transfer port 25. In another arrangement closure bag slides over a rigid former extending outwardly from the transfer port and cutter sealer cuts and seals portions of the closure bag across the disposal bag by cooperating with a backing member in the closure bag. In both arrangements the interior surface of the closure bag is medically clean and after cutting and sealing the surface forms outer surfaces of the disposal bag 21 and transfer port 25. <IMAGE>

Title: Lithographic etch fix
IPC: G03F7/06
Filed: 1981-04-02
Abstract: The invention relates to a composition for rendering oleophilic a silver image e.g. one which has been produced by the photographic silver salt diffusion transfer process at a water- accepting surface.   UK patent specification 1406030 describes and claims inter alia aqueous lithographic fix compositions comprising an acid, iodide ions, an organic cationic compound containing a lipophilic group and either an organic cationic compound having an aromatic group but no nitro group or, when the silver image requires more oxidation as a step in the process of rendering the silver oleophilic, a heterocyclic organic compound having a nitro group bonded to an aromatic nucleus. It has now been found desirable to use alternative organic cationic compounds having an aromatic group but no nitro group. The present invention provides an aqueous lithographic fix composition containing:   (i) if necessary an acid or an alkali to give a pH from 1 to 10, preferably between 3 and 7;   (ii) iodide ions; (iii) an organic cationic compound containing a lipophilic group; and     (iv) a quinoxalinium compound. u
