Title: Acid composition comprising a coated polyvalent carboxylic acid solid particle and a powder coating comprising the same
Inventor: AMEY RONALD LEE
IPC: B32B5/16
Filed: 1996-08-23
Abstract: An acid composition comprises a polyvalent carboxylic acid solid particle coated with a polymer. The acid composition may function as a cross-linking agent in a powder coating, which also includes a resin. The resin and the polymer of the acid composition may be the same, or they may be different. The mean particle size of the coated acid solid particles is in the range of 0.5 to 50 micrometers. When used in a powder coating, such coated solid particles reduce or eliminate sublimation of the acid crosslinking agent from the powder coating during the curing step. In addition, these coated solid particles increase the storage shelf-life of the powder coating in which they are used.  Such coated particles also improve the flow characteristics of the powder coating during curing thereof and the gloss and surface quality of the final cured coating.

Title: Route finding in communications networks
Inventor: JOHNSON DAVID
IPC: H04L12/701
Filed: 1996-08-06
Abstract: A method of determining a restoration route (or an additional route) in a fully or partially meshed communications network of nodes, comprising setting, at a node which initially determines itself to be the slave end node for an existing route, a timeout for receiving a number of forward route-finder signatures from which it will select the signature representing the potential restoration route having the shortest length and return a route confirmation signature; switching, if no route-finder signatures have been received by the expiry of the timeout, to act as master end node for the existing route and send reverse route-finder signatures to its neighbouring nodes; switching, upon receipt of a reverse route-finder signature at a node which initially determines itself to be the master end node for an existing route, to act as slave end node, and send a corresponding return signature. Where a slave end node receives a backtrack signature indicating that the potential restoration route no longer has sufficient capacity, the node will switch to act as master end node. Where a forward route-finder signature is received after a node has sent a reverse route-finder signature, a priority route confirmation signature is sent. The route-finder signatures have a count field to indicate the direction of travel and the number of times that the sending node has switched to act as master end node, forward signatures have counts 1,3, etc..., and reverse signatures have counts 2,4, etc... Where a node has sent a forward route-finder signature, received a reverse route-finder signature, sent a confirmation signature, and subsequently receives a priority confirmation signature, then unless a backtrack signature is received two restoration routes will be established and the nodes will select the better one.

Title: Process and device for carrying out quantitative, fluorescence affinity tests
Inventor: KATERKAMP ANDREAS
IPC: G01N21/77
Filed: 1997-07-11
Abstract: A process and device are disclosed for carrying out in particular quantitative fluorescence immunity tests by means of evancacent field excitation, possibly on the basis of various known biochemical assays of systems generally composed of receptor-ligands. However, antibody-antigen systems are preferably evaluated. The invention should enable quantitative fluorescence immunity tests with various known biochemical assays to be carried out with a very simple device. For that purpose, a light source (7, 7) is used which emits rays of an almost monochromatic light having a wavelength which causes a marking substance bound to the antibody to become fluorescent. The light rays are directed at an angle .alpha. determined by a depth of penetration d previously determined for the evanescent field onto a boundary surface (20) between an optically transparent base plate (i) made of a material with a refraction index n1 higher than the refraction index n2 of the material above the boundary surface (20) and a cuvette-shaped sample-receiving area (2). The sample receiving area (2) is covered at the side opposite to the base plate (1) by a covering plate (3) and a detector (5) for sensing fluorescent light is arranged at the same side of the base plate (1) as the light source (7).
