Title: Magnetostrictive element having optimized bias-field-dependent resonant frequency characteristic
Inventor: O'HANDLEY ROBERT C
IPC: G01V3/00
Filed: 1998-02-04
Abstract: A magnetostrictive element for use in an magnetomechanical marker has a resonant frequency characteristic that is at a minimum at a bias field level corresponding to the operation point of the magnetomechancial marker. The magnetostrictive element has a magnetomechanical coupling factor k in the range 0.28 to 0.4 at the operating point (26). The magnetostrictive element is formed by applying current-annealing to an iron-nickel-cobalt based amorphous metal ribbon, or by cross-field annealing an iron-nickel-cobalt alloy that includes a few percent chromium and/or niobium.

Patent CA-2282047-A1 (CA)
Inventor: BARGHI SHAHZAD
IPC: G01N31/10
Filed: 1999-08-30
Abstract: This invention is directed to a method of monitoring the relative activity of various heterogeneous catalysts by analysing their bulk electrical properties such as specific conductivity or resistance. The difference between the resistance of fresh and spent catalysts is to be large (as high as four orders of magnitude). These large differences make this invention a very sensitive indicator of changes that may happen at the surface and/or in the bulk of the catalyst. The simplicity of this new invention renders it to be a sensitive potential on-line testing method of catalyst activity.

Title: N x m optical wavelength routing switch
Inventor: LIU JIAN-YU
IPC: H04B10/29
Filed: 1998-04-07
Abstract: A switchable wavelength router switches wavelength division multiplexed (WDM) optical signals between N input ports (101, 102) and M output ports (103, 104, 105). Each WDM signal is spatially decomposed into N pairs of orthogonally polarized beams by a polarization-dependent routing element, such as a birefringent element (201). A polarization rotator array (204) rotates the polarization of each beam pair so that both beams in each pair have the same polarization. A wavelength filter (206) then demultiplexes each beam pair to create N sets of four beams. A second polarization-dependent routing element (202) spatially routes the four beams in each of the N sets based on their polarizations, and also spatially combines selected beam pairs from different sets to produce M pairs of beams. A second polarization rotator array (205) restores each beam pair to orthogonal polarization, and a final polarization-dependent routing element (203) recombines each beam pair to produce M output beams at the output ports (103, 104, 105).

A second disclosed method involves preparing an enhanced efficacy aluminum antiperspirant salt by heating an aqueous solution of an aluminum antiperspirant salt in the presence of a polyhydric alcohol having from 3 to 6 carbon atoms and from 3 to 6 hydroxyl groups at a temperature of at least 50 °C for a time sufficient to convert the salt to an enhanced salt. A  third disclosed method is an improvement in the method of making an aluminum hydroxy halide or an aluminum hydroxy nitrate by reacting aluminum with an aqueous solution of aluminum halide or aluminum nitrate (or with aqueous hydrogen halide or nitric acid), wherein the improvement comprises including a polyhydric alcohol having from 3 to 6 carbon atoms and from 3 to 6 hydroxyl groups in the reaction mixture.  Also disclosed are compositions produced by the foregoing methods.

Title: Lossless image compression with tree coding
Inventor: THORELL PER
IPC: G06T9/40
Filed: 1998-05-07
Abstract: In a method and a device for coding binary matrices, in particular sparse binary matrices, a matrix is gradually partitioned into sub-matrices. During the gradual partitioning the number of binary ones are counted for each resulting sub-matrix. If a resulting does not consist of mixed symbols no further partitioning of that sub-matrix is required. The counted number of binary ones for each sub- matrix is then coded and transmitted. The method provides an efficient coding particularly for sparse binary matrices such as bi-level images or bit maps.

Abstract: A pair of suspenders comprises two comparatively long straps of a given width. Each of the comparatively long straps has a front portion terminating at a front end and a back portion terminating at a back end. The back portions cross each other. Moreover, a comparatively short strap having two opposite ends is affixed at each of the opposite ends to the back portion of each of the comparatively long straps so as to define a loop, which has an overall length that is at least several times greater than the given width of the comparatively long straps. One of the straps defining each of the loops passes through the other loop, whereby the loops enable the pair of suspenders, over a range of shoulder-to-shoulder spacings, to conform automatically to the shoulder-to-shoulder spacing of a wearer. The comparatively long straps are substantially inelastic. Furthermore, an elastic strap is attached to the each of the front and back portions of each of the comparatively long straps and each of the elastic straps has a distal end, to which a fastener is attached for fastening the elastic strap to a pair of pants. Preferably, the fastener is a wire loop, which is shaped to coact with a button on the pair of pants. Alternatively, the fastener is a clip, which is adapted to clip onto the pair of pants.

Abstract: Communication nodes 510, 520, 530, 540, 550 are circularly connected by using two-way fibers 501-1 to 501-5 (hereafter, referred to simply as 501) and 502-1 to 502-5 (hereafter, referred to simply as 502). On the physical transmission network of (a), a working light wave path 560-N of a wavelength of .lambda.i is set through the communication node 550 between the communication node 510 and the communication node 540 as shown in (b).  Between the communication node 510 and the communication node 540, a working light wave path 561-N is set through the communication nodes 520, 530.      Between the communication node 520 and the communication node 530, a working light wave path 570-N of a wavelength of .lambda.j is set through the communication nodes 510, 550, 540.  Between the communication node 520 and the communication node 530, a working light wave path 571-N of a wavelength of .lambda.j provided between them is set, and a total of four working light wave paths are set. All the working light wave paths 560-N, 561-N, 570-N, 571-N are set by using two-way fibers 501. To each of the working light wave paths 560-N, 561-N, 570-N, 571-N, standby light wave paths used as detours at the time of an obstacle are physically prepared both in the span direction (the same direction as the working light wave path) and in the ring direction (opposite direction of the working light wave path) on two-way fibers 502, but they are not set logically. The working light wave paths 560-N, 561-N and the standby light wave paths for them have the same wavelength of .lambda.i. The working light wave paths 570-N, 571-N and the standby light wave paths for them have the same wavelength of .lambda.j.

Abstract: L'invention concerne un procédé servant à traiter un article et, plus particulièrement, une surface d'aéronef, de manière à empêcher la formation de givre, ainsi qu'un revêtement dégageant une quantité très limitée de constituants organiques volatils (VOC) pendant son application et son durcissement. La formation de givre sur des surfaces critiques d'aéronefs, tels que des avions, crée des conditions dangereuses portant préjudice à la stabilité de l'avion. On désigne ces zones spécifiques en tant que zones d'infiltration de froid, dont la plupart se trouvent sur les bords avant des ailes. L'invention permet d'éliminer givre de ces surfaces. Le givre provoqué par les intempéries représente un problème annexe mais ne constitue parle problème direct traité par l'invention. Le givre ne se formera pas à la surface de certains revêtements polymères présentant une faible énergie de surface, tels que le Téflon?TM¿. Ceci provient de l'existence d'un angle de contact important entre la gouttelette d'eau et la surface, ce qui crée une surface non humidifiante. L'invention a pour objectif de mettre en application ces revêtements et un procédé de dépôt. Une mise en application efficace permettra également d'obtenir une formulation de revêtement et un procédé de dépôt. On peut utiliser ce revêtement pour d'autres objets, tels que des automobiles et des produits de consommation, tels que des réfrigérateurs ou des cuisinières.
