Title: High activity ziegler-natta catalyst for high molecular
Inventor: VACLAV GEORGE ZBORIL
IPC: C08F10/00
Filed: 2002-05-23
Abstract: By controlling the hold up times, concentrations and temperatures for mixing the components of aluminum, titanium and magnesium based catalyst for solution polymerization it is possible to prepare a catalyst having a high activity, which prepares high molecular weight polyolefins.      Generally, a catalyst loses activity and produces lower molecular weight polymer at higher temperatures. The catalyst of the present invention permits comparable polymers to be produced with higher catalyst activity and at higher reaction temperatures by increasing the concentration of the components used during the preparation of the catalyst.

Patent CA-2388691-A1 (CA)
Inventor: HOLLIER MICHAEL PETER
IPC: G10L19/00
Filed: 2000-10-26
Abstract: This invention relates to non-intrusive speech-quality assessment using vocal-tract models, in particular for testing telecommunications systems and equipment. This process requires the reduction of the speech stream under assessment into a set of parameters that are sensitive to the types of distortion to be assessed. Once parameterised, the data is used to generate a set of physiologically-based rules for error identification, using a parametric modelling of the shape of the vocal tract itself, by comparison between derived parameters and the output of models of physiologically realistic forms for the vocal tract, and the application of physical constraints on how these can change over time.

Title: Method and device for improving communication in a vehicle
Inventor: FELS PETER
IPC: H04R5/02
Filed: 2000-11-09
Abstract: The invention relates to the improvement of communication in a vehicle, whereby speech signals generated by passengers in a vehicle are recorded individually by specially arranged microphones (M1-M4). The individually recorded speech signals from each passenger (1-4) are amplified separately i n an input step (7) and filtered in order to minimize start levels and adapt frequencies. Said signals are processed individually for each output channel , whereby correction of propagation time and level differentiation is performe d and each signal is separated via by means of an adaptation step (9), which comprises level adaptation, amongst equally individually on specially assign ed loud speakers (L10-L14), according to spatial conditions prevailing in the vehicle and in accordance with the desired volume. The inventive method is f or passenger vehicles. Utilization of said invention in larger vehicles e.g. in  special, multimedia bus vehicles, and in load-carrying vehicles and other means of transport such as ships, trains and aircraft is however also conceivable.

Abstract: L'invention concerne des formes posologiques étendues de stavudine comprenant des granules formés par extrusion-sphéronisation et recouverts d'un revêtement hermétique. Les granules sont également recouverts d'un revêtement détachable modifié de sorte qu'une capsule de gélatine dure contenant ces granules libère un certain taux de stavudine dans le sang pendant environ 24 heures. Ces granules sont préparés à partir d'un mélange sec de stavudine, d'un agent de sphéronisation, d'un diluant approprié et d'une quantité stabilisatrice de stéarate de magnésium. On a découvert que le stéarate de magnésium, contrairement à d'autres traitements d'appoint pharmaceutiques, stabilise la stavudine contre une dégradation due à l'hydrolyse en présence de la quantité limitée d'eau nécessaire au procédé d'extrusion-sphéronisation. L'invention concerne également des capsules de gélatine dure contenant, outre les granules de stavudine, des granules semblables contenant d'autres agents thérapeutiques servant à traiter des infections rétrovirales.
