Patent CA-2283121-A1 (CA)
Title: Balanced wire connector
Inventor: BROWER BOYD G
IPC: H01R4/2433
Filed: 1999-09-23
Abstract: A weatherproof protector module for telecommunication circuits has wire insertion points that are arranged in lateral, forward and rearward symmetry about a single stuffer screw. The module contains J-shaped insulation displacement connectors (IDCs) with slits for engaging the wires. The symmetry of the module allows the screw to exert balanced forces in every direction as the wires engage the IDCs. The module also contains an insulative gel that is extruded around the wire contact locations when the wires are engaged. A wiper seal located each wire insertion point and a thixotropic gel prevent the expulsion of the insulative gel from the module after extrusion.

Title: Aluminium compound, method for producing the same, catalyst for producing olefinic polymers and method for producing olefinic polymers
Inventor: OKUDA FUMIO
IPC: C08F10/00
Filed: 1999-02-25
Abstract: A catalyst for olefinic polymer production comprises (a) a penta-coordinated, organic aluminium oxide compound, (b) an alkylating agent and (c) a compound of a transition metal of Group IV, V, VI or VIII of the Periodic Table. Olefins are homopolymerized or copolymerized in the presence of the catalyst for olefinic polymer production to produce olefinic polymers. The process does not require a promoter of methylaluminoxane, with which the problem is low solubility and low storage stability. Using therein the penta-coordinated, organic aluminium oxide compound which is relatively inexpensive and can be produced easily, the process realizes high-yield production of olefinic polymers.

Title: Transport lock for forwardly folding agricultural implements
Inventor: FRIGGSTAD TERRANCE A
IPC: A01B73/06
Filed: 1999-11-10
Abstract: An agricultural planter is provided with wing members that fold forwardly from a laterally extending operating position to a compact transport position. The wing members are supported on wheel assemblies when in both the operating and transport positions. A transport lock mechanism is operable to secure the forwardly folded wing assemblies in the transport position against the draw bar. A latch tower having vertically oriented latch retainer bars permit the wing members to move vertically relative to the draw bar without disengaging the transport lock to allow the wing member wheel assemblies to follow ground undulations in the transport position. A wheel lock is also provided to convert the wheel assemblies between a forwardly fixed position used when the wing members are in the operating position and a castering position that enables the wing members to move into the transport position. A wing latch actuator interconnects the transport lock mechanism and the wheel lock mechanism to effect operation thereof in a coordinated manner.

Patent CA-2305652-A1 (CA)
Inventor: BERGER JENS
IPC: G10L19/00
Filed: 1999-08-14
Abstract: Known methods for instrumental voice quality evaluation based on comparing signal intensities of the voice signal to be evaluated with a reference voice signal do not optimally evaluate spectral distortions in the voice signal to be evaluated so that quality evaluation is unreliable. Moreover, by integrating the signal intensity in the frequency bands with constant band limits, certain falsifications of the voice signal to be evaluated, such as those caused, for instance, by coding systems with lower bit rates, are erroneously evaluated. In order to enhance prediction reliability of the evaluated quality parameters, distortions of the mean spectral envelope are extensively corrected with a weighting function WT(f) before comparing spectral properties. On the other hand, the fixed band limits for integration of spectral power density are suppressed and other band limits are searched for instead in a predetermined optimization area in which the resulting spectral intensity representations of the voice signal to be evaluated and the reference voice signal have maximum similarity. The solutions described can supplement known methods and can be incorporated into their structures.

Patent CA-2309087-A1 (CA)
Inventor: LEE YEUK-MUI
IPC: G01N33/533
Filed: 1998-10-27
Abstract: Methods for detecting parasites, such as Cryptosporidium parvum, in turbid and non-turbid samples by solubilizing molecular markers or antigens of the parasite. The molecular markers are solubilized by incubating a sample containing the parasite with a solubilization buffer and detecting the solubilized antigens by electrochemiluminescence. The solubilization buffer contains one or more detergents alone in or combination with one or more denaturing agents in a buffered solution. The methods are an improvement over existing immunofluorescence assays for C. parvum because the methods described herein are quantitative, reproducible, have high sensitivity, are not labor-intensive, require only minimal sample processing, and avoid being adversely affected by sample turbidity. In addition, by using an electrochemiluminescence assay, microscopy is not required.

Abstract: La taille optimale d'un bloc de données est déterminée aux fins de transmission de données à des vitesses variables par une liaison de communication à des intervalles temps prédéterminés, chaque intervalle étant de durée identique. Plutôt que de faire varier la taille du bloc de données en fonction des changements de la vitesse de transmission, ce qui génère une complexité superflue, les blocs de données ont tous la même taille fixée, notamment le même nombre de bits de données dans chaque bloc. Cette taille fixée du bloc de données est déterminée de telle façon que pour toutes les vitesses de transmission disponibles, chaque intervalle de temps prédéterminé, est entièrement occupé par des informations utiles. La taille fixée de bloc de données est déterminée sur la base d'une fréquence maximale à laquelle la vitesse de transmission peut changer sur la liaison de communication et d'une vitesse de transmission disponible la plus basse possible. De préférence, la taille fixée de chaque bloc de données est limitée par des tailles minimale et maximale prédéterminées des blocs de données afin de réduire le nombre d'erreurs sur les bits par bloc de données, de conserver un certain débit de données et de limiter la quantité de bits supplémentaires par rapport au nombre de bits de données utiles de chaque bloc de données.
