Title: Method for the enzymatic production of a curing agent in its fluid state
Inventor: CASEZ HERVE
IPC: C12N11/00
Filed: 2002-05-31
Abstract: The invention relates to a method for the enzymatic production of a curing agent in its fluid state, e.g. liquid, comprising, in free phase, at least one oxygenated chemical species. Said method consists in bringing into contact at least: one enzymatic catalysis agent, comprising at least one peroxidase-type enzyme; an oxidisable substrate in aqueous phase that can be oxidised by the action of an oxygen donor, by catalysis by said enzymatic catalysis agent, generating said oxygenated chemical species in free phase; and said oxygen donor. The inventive method is characterised in that: e) an aqueous reaction bath is formed comprising, in addition to the oxidisable substrate and the oxygen donor, said enzymatic catalysis agent in divided solid phase, but in free phase, distributed in said bath, which may be set in motion; f) the aqueous reaction bath is separated into a fraction enriched with the enzymatic catalysis agent in divided solid phase and a fraction free from said catalysis agent, from which the curing agent is obtained.

Patent CA-2448641-A1 (CA)
Inventor: FANG RONG C
IPC: H04L12/42
Filed: 2002-05-24
Abstract: A single, normally inactive, protection ring (22) provides protection against a working channel failure in a fiber optic ring network (10). The protection channel (22) is established and put into operation by a series of steps that are triggered by the detection of signal degradation or loss of light from one transponder by the other transponder. Each node (20A, 20B, 20C, 20D) reacts to a failure of another node in substantially the same way. Incoming traffic from external sources is rerouted from a working input-output interface to a protection interface, to establish a path for the protection signal. Signals are sent between nodes enabling the two nodes to resume communication. Only the portion of the protection ring (22) between nodes (20A, 20B, 20C, 20D) is placed into service.
