Patent CA-2275008-A1 (CA)
Title: Filter arrangement
Inventor: REUSENS PETER PAUL FRANS
IPC: H04M11/06
Filed: 1999-06-15
Abstract: A filter arrangement (FA) particularly adapted to be used in a "splitter" (SP1) of an ADSL system where several POTS equipments (POTS1-POTS3), e.g. subscriber sets, are connected to a same telecommunication line (TP). The arrangement, located at the customer premises (CP), includes for each POTS equipment a distinct low-pass filter circuit (LP; LP1-3) to separate low frequency POTS signals from high frequency ADSL signals simultaneously transmitted over the same copper twisted-pair telecommunication line (TP). Each low-pass filter circuit is provided with a current sensing circuit (SC), e.g. an electrical relay, that activates a switch (SW) when the current flowing through the filter exceeds a predetermined value. Since several high order filter circuits can not be put in parallel, mainly because their capacitive values will then add, the present filter circuit is basically a 1st order filter that comprises the series connection of two transformers (T1, T2) separated by the coil of the relay. When the current increases, i.e. because the associated subscriber set goes off-hook, the switch activated by the relay inserts a capacitor across the line and between the two transformers. The filter circuit becomes then a 3rd order filter that is constituted by the cascade connection of the first transformer (T1), the capacitor (C) and the second transformer (T2). Since the order to the other filters circuits of the arrangement is not changed, there is no mutual disturbance.

Patent CA-2280475-A1 (CA)
Title: Improved spray nozzle design
Inventor: SPINK DONALD R
IPC: B05B7/04
Filed: 1991-09-03
Abstract: Novel cluster nozzle designs useful for the formation of atomized sprays of fine liquid droplets in a continuous gas phase are described. A plurality of individual gas-liquid mixing zones communicate with a common source of liquid and a common source of gas to form gas-liquid mixtures for spraying from individual orifices in the nozzle. An improved uniformity of spray pattern is attained, as well as the ability to effect a greater liquid output from the nozzle through the use of larger size or numbers of orifices, while retaining very uniform sprays, by effecting a degree of premixing of liquid and gas before passage to the individual gas-liquid mixing zones.
Patent CA-2280819-A1 (CA)
Title: Digital signal compression encoding with improved quantisation
Inventor: WELLS NICHOLAS DOMINIC
IPC: H04N7/30
Filed: 1998-02-25
Abstract: In compression encoding of a digital signal, such as MPEG2, transform coefficients are quantised with the lower bound of each interval being controlled by a parameter .lambda.. In the MPEG2 reference coder, for example, .lambda.=0.75. Because the quantised coefficients are variable length coded, improved quality or reduced bit rates can be achieved by controlling .lambda.  so as to vary dynamically the bound of each interval with respect to the associated representation level. The parameter .lambda. can vary with coefficient amplitude, with frequency, with quantisation step size. In a transcoding operation, .lambda. can also vary with parameters in the initial coding operation.

Les impulsions courtes réduisent les effets thermiques indésirables et les variations au voisinage des niveaux potentiellement submicroniques. La source de rayonnement paramétriquement divisée produit de préférence des pulsations dont la durée est inférieure à 25 ns ou voisines de 3,0 µm, mais de préférence vo isine du maximum d'absorption de l'eau caractéristique du tissu. La division jusqu'à la longueur d'ondes voulue de l'infrarouge moyen s'obtient de préférence au moyen d'un cristal non linéaire (15) tel que le KTP (potassium-titanyle-phosphate) ou ses isomorphes. Selon une réalisation, on utilise un cristal accordé en phase de façon non critique pour prendre la longueur d'ondes d'une source laser émettant dans le proche infrarouge exactement ou au voisinage des 880 à 900 nm et la décaler jusqu'à la plage attendue de valeurs de longueurs d'ondes de 2,9 à 3,0 µm.

Title: Positively expanding and retracting medical extractor

Filed: 1998-04-29
Abstract: A medical extractor comprising a canula assembly having an annularly expanding and retracting gripping and releasing mechanism on the distal end thereof and a moving assembly on the proximal end thereof. The arrangement is such that a manual movement of the moving assembly in one direction effects a longitudinally outward movement of an annular array of longitudinally movable wire flexure elements within an annular array of longitudinally fixed tubular flexure elements to cause the fixed flexure elements to flex transversely outwardly and create an annularly expanded condition defined by an annular series of transversely outwardly flexed fixed flexure elements interconnected at their ends by an annular series of arcuately outwardly flexed portions of the movable flexure elements. A manual movement in the opposite direction effects a longitudinally inward movement of the movable flexure elements to cause the expanded condition to progressively retract during which the outwardly flexed fixed flexure elements are progressively less flexed transversely outwardly and the arcuately flexed portions of the movable flexure elements have a progressively less arcuate extent.
