Patent CA-2191474-A1 (CA)
Title: Process for producing multi-layer molded articles
Inventor: ISHITOYA KATSUNORI
IPC: B29C48/00
Filed: 1996-03-07
Abstract: A multi-layer molded article such as a door trim is produced by extruding a molten surfacing resin layer (13m) forming a soft thin surface layer (13), a molten intermediate resin layer (12m) forming an expanded soft interlayer (12), and a molten resin layer (11m) forming a support (11) through dieheads (40) of extruders into sheets, feeding these sheets in such a state that the molten resin layer (11m) comes into contact with a bottom tool (20), and compression-molding the sheets. It is preferable that the molten surfacing resin layer (13m) be composed of a thermoplastic elastomer, the molten intermediate resin layer (12m) be composed of an ethylenic copolymer comprising at least ethylene and a radical-polymerizable acid anhydride and containing a blowing agent, and the molten resin layer (11m) be composed of an olefinic resin. Further, it is preferable that the thermoplastic elastomer be an olefinic thermoplastic elastomer and/or a styrenic one having a melt flow rate of 0.1 to 200 g/10 min as determined at 230 °C under a load of 2.16 kg and a Shore A hardness of 50 to 96. Furthermore, it is preferable that at least two of the molten resin layers be laminated in a diehead and extruded and fed in the form of a multi-layer sheet. Additionally, the molten resin layer (11m) may preliminarily be molded and put on the bottom tool, followed by the extrusion thereonto of a multi-layer sheet comprising the molten intermediate and surfacing resin layers (12m and 13m).
Patent CA-2191758-A1 (CA)
Title: Stereospecific catalyst system for polymerization of olefins
Inventor: IISKOLA EERO
IPC: C08F10/00
Filed: 1995-05-30
Abstract: Olefins or mixtures of olefins, particularly propene or mixtures of propene advantageously with ethene, can be polymerized using a Ziegler-Natta catalyst system containing, besides a transition-metal-based procatalyst and cocatalyst which is an organometallic compound, a compound particularly suited for controlling the stereospecificity of the produced polymer. Such a compound called an external donor may also have other effects. By using an acetal derivative of an aldehyde that has two ether groups for this purpose, advantageously selected from the group of dialkoxyphenylalkanes, e.g., dimethoxyphenylpropane, a good stereospecificity of the product is attained combined with the high hydrogen sensitivity of the catalyst system, whereby the use of hydrogen as the chain transfer agent offers an easy control method of the molecular weight of the product by means of adjusting the amount of hydrogen available in the polymerization reaction. If with the acetal derivative donor is used a clearly less hydrogen sensitive donor, e.g. alkoxysilanes, much broader MWD's of the product are achieved.

Title: Two-Stage Kraft Cooking
Inventor: LI JIAN
IPC: D21C3/26
Filed: 1995-07-17
Abstract: A method for the production of kraft pulps in a digester, by modifying the cooking chemical concentration, and lignin concentrationprofiles during the cook, has provided extended delignification and improved selectivity in a simpler way than has previously been possible. The cooking is performed at an elevated temperature in two stages. The first stage liquor is a mixture of 1) the spent liquor of the second stage and 2) a portion of the conventional charge of fresh cooking chemicals needed for the complete cook. The second stage liquor is made up by adding an aqueous diluent, for example, fresh water or washing filtrate to the remaining portion of the fresh cooking chemicals.

Title: Detecteur-extincteur automatique residentiel
Inventor: GRENIER JEAN
IPC: A62C35/10
Filed: 1997-02-04
Abstract: Dans les systèmes de protection d'incendie pour maison résidentiel on ne retrouve que les détecteurs de fumée et les extincteurs manuels qui parfois dans certaines situations deviennent inutile si l'extincteur est inaccessible dû à l'ampleur du feu ou détecté trop tard.

Patent CA-2197961-A1 (CA)
Inventor: POHNDORF PETER J
IPC: A61M5/14
Filed: 1997-02-19
Abstract: An introducer system for a lead, catheter, probe or the like, employing a dilator and introducer sheath assembly for dilating a body vessel in preparation for introducing the lead, etc., through the lumen of the introducer sheath that is easily advanced into the body vessel while minimizing injury to the vessel wall. The elongated tubular dilator is formed with a tapered distal end portion extending proximally of a reduced diameter distal tip end to a relatively uniform major diameter. The introducer sheath major lumen diameter is dimensioned to fit snugly over themajor diameter and to have a reduced distal end opening diameter from the major lumen diameter. An annular recess is formed in the dilator adjacent to the distal end portion for receiving the reduced distal end opening diameter, such that when soassembled, a smooth transition of the dilator and sheath outer surfaces are presented proximal to the tapered distal end portion. The introducer sheath wall thickness may also be tapered in a distal introducer sheath portion. The annular recess and/or the sheath distal end opening are shaped to provide a cam surface to allow retraction of the distal end portion of the dilator past the reduced diameter sheath distal end opening. The sheath preferably is constructed to readily tear in a longitudinal direction and thus permits the system to be removed from the venous system without having to withdraw the sheath over an end of the lead, etc.

Patent CA-2199146-A1 (CA)
Title: Detection device and method
Inventor: WRIGHT KEVIN MICHAEL
IPC: G01J3/28
Filed: 1995-09-28
Abstract: The invention is a device for the multiplex detection of a plurality of characteristic signals from a plurality of samples. Previous multiplex systems using Hadamard transform multiplexing were often limited to 4n-1 samples (n =  1, 2, 3 etc.). The present invention overcomes this limitations by encoding signals after they had been modulated by a sine function or a cosine function (or a combination of sine and cosine functions). Such modulation of signals using the "sine/cosine transform" is easier to implement than Hadamard transforms and there is no limitation imposed on the number of samples.
