Title: Compositions and methods for disinfecting a contact lens and detecting the presence of an oxidative disinfectant
Inventor: PARK JOHN Y
IPC: A61L12/12
Filed: 1996-06-26
Abstract: Compositions and methods useful for disinfecting a contact lens are disclosed.  The present methods comprise contacting a contact lens with a liquid medium containing an effective amount of an oxidative disinfectant component at conditions to effectively disinfect the contact lens. The contacting occurs in the presence of a color indicator component which is soluble in the liquid medium and is adapted to provide a color indication of the presence of the oxidative disinfectant component in the liquid medium. The color indicator component comprises an effective amount of a transition metal component which is redox active, has an oxidized state of a first color and a reduced state of a different second color and a polyanionic component in an amount effective to inhibit the staining of the contact lens by the transition metal component.

Title: Synchronized electronic network including backup masters
Inventor: GHAFFARI TOURAJ
IPC: H04J3/06
Filed: 1996-07-10
Abstract: Operation of a plurality of electronic devices (56M) is synchronized. The plurality of devices includes a master unit (56M-1) and a plurality of other units (56M/S), and the master unit (56M-1) transmits a synchronizing signal (301) to at least one of the other units (56M) at predetermined intervals. Each of at least two of the other units (56M) detects whether a synchronizing signal is received at the respective unit (56M) within a predetermined period of time. If not, the respective unit changes from a slave mode of operation to a master mode of operation. Contention between the two or more potential back-up master units (56M) is resolved based on priority in a daisy-chain arrangement or by providing different time-out watch-dog periods for the potential back-up devices.

Title: Method of gasifying coal and related installation
Inventor: KARPENKO EVGENY IVANOVICH
IPC: C10J3/46
Filed: 1996-01-03
Abstract: The invention is in the field of power engineering, specifically the thermal processing of coal, and can be used in thermal power plants for refining low-grade coal to produce environmentally clean synthesis gas. To enhance the fuel's reactivity and increase the output of synthesis gas, a portion of fuel undergoes electro-thermo-chemical preparation in advance; this involves directing the dust-air mixture through preparation chambers (PC) (2 and 3).  There a stream of low-temperature plasma is generated, and the combustion products are then directed towards the reaction chamber (RC) (1), into which the main stream of pulverised fuel and gasifying agent are tangentially introduced, and complete gasification of the fuel occurs. The installation for applying this method comprises a vertically positioned reaction chamber (RC) (1) whose lower part is linked with at least two preparation chambers (PC) (2 and 3), placed diametrally for advance electro-thermo-chemical processing of the fuel. Each preparation chamber (PC) is made as a muffle (4) with a built-in plasma generator (5) and the muffles (4) are connected to the reaction chamber (RC) (1) tangentially and face-to-face. The means for introducing into the reaction chamber (RC) (1) the main stream of coal dust and gasifying agent are positioned diametrally and are tangentially connected to the reaction chamber (RC) (1).

Patent CA-2249955-A1 (CA)
Inventor: BURKE NICHOLAS A D
IPC: C08F291/18
Filed: 1998-10-13
Abstract: Graft copolymers having side chains or branches of substantially uniform length and molecular weight are prepared by a process in which the backbone polymer is treated to create carbon centered free radicals thereon, e.g. by radiation, in the presence of a stable free radical compound. The free radical sites bond to the stable free radical through thermally labile bonds, so that heating of the "labelled" polymer in the presence of polymerizable monomer causes re-formation of the carbon centered free radicals with dissociation of the polymer-stable free radical compound bond, to effect graft copolymerization of the monomer. Controlled polymerization takes place by repetition of the three steps (dissociation, monomer addition, re-association) to give a graft copolymer with substantially uniform branch chains, each capped with a stable free radical group.

Abstract: The present invention provides a reconfigurable optical add-drop multiplexes for a wavelength division multiplexed optical communication system. The recon-figurable add-drop multiplexes includes a static optical add-drop multiplexes including an input port for receiv-ing optical signals from an optical transmission path in a wavelength division multiplexed optical communica-tion system, a drop port for routing optical channels to be removed from an optical transmission path, and add port for receiving optical channels to be added to an optical transmission path, and wavelength selecting means for selecting optical channels to be dropped from the optical transmission path. An optical path com-municates with the drop port, which includes an op-tical demultiplexer having an input port for receiving the dropped optical channels and plural demultiplexer output ports for separately outputting optical channels.      Plural demultiplexer optical paths optically communi-cate with the optical demultiplexer for receiving each of the dropped optical channels. Similarly, an optical path optically communicates with the add port of the static add-drop multiplexer. The add optical path includes an optical combiner having plural combiner input ports communicating with plural combiner optical paths for receiving optical channels to be added to the optical transmission path and an output port for outputting a combined optical signal comprising the optical channels received from the combiner input ports. An optical switch is positioned in one or more of the demultiplexer optical paths, which permits switching of a dropped optical channel between a receiver optical path for directing the dropped optical signal to an optical receiver and between a combiner optical path for routing the dropped optical channel back towards the optical transmission path optionally passing the dropped optical channel through a remodulator. Alternatively, the optical switch routes the dropped optical channel towards an optical receiver while permitting a new optical channel to be routed to add port of the static add-drop multiplexer.
