Title: Method of forming a silicon layer on a surface
Inventor: BEGUIN ALAIN
IPC: C23C14/18
Filed: 1998-05-26
Abstract: A method of forming a layer of silicon on a surface of a substrate (10) comprises the steps of depositing silicon on the surface by a physical deposition process such as electron beam evaporation using a silicon source (4) and, during said deposition process, subjecting the forming film to ionic bombardment from an ion gun (20). The resultant silicon film has stresses which are considerably reduced compared to a film produced by an ordinary physical deposition process. This method is particularly well adapted to the formation of relatively thick silicon layers (lµm) on a layer (or stack of layers) of silica, to serve as an etching mask in a subsequent deep etching of the silica by reactive ion etching.

Patent CA-2300597-A1 (CA)
Inventor: LIU RONG FAN
IPC: B60L3/10
Filed: 2000-03-10
Abstract: The drive motor (12) of a powered axle on an electric train is energized e.g. from a supply source (14) having a 3-phase output regulated by a motor controller (18) whose basic function is to establish a motor torque corresponding to a set input value (Cmanip). The motor controller is integrated with an adhesion control unit (20) comprising the adhesion controller proper (22) and a processor (24). The adhesion control unit receives input (V) from a motor speed sensor (26) and passes to the controller signals representing the first (i.e. acceleration) (gamma) and second (Dgamma) derivatives of this variable. The speed sensor signal is also delivered to the motor controller (18) and, directly, to the adhesion controller (22). The motor controller also has input a motor supply current value through connections (IS1,IS2) from two of the supply phases. From its inputs, the motor controller estimates the motor torque and inputs a corresponding signal (Cm) to the adhesion controller. The latter's output signal (C-corr) modifies the motor controller setting (Cmanip) in a subtracter unit (27) to give a corrected setting signal (Ccons). The adhesion controller then responds to motor accelerations indicative of increased slip by reducing the torque setting (Ccons) of the motor controller (18).

Abstract: Cette invention concerne des 3-(4-pipéridinyl)indoles substitués qui sont des modulateurs, des agonistes ou des antagonistes du récepteur CCR5. Cette invention concerne également le traitement et la prévention d'états pathologiques induits par CCR5 comprenant entre autre l'asthme et les troubles atopiques (par exemple la dermatite atopique et les allergies atopiques), la polyarthrite rhumatoïde, la sarcoïdose et d'autres maladies fibreuses, l'athérosclérose, le psoriasis, les maladies autoimmunes telles que la sclérose en plaques et la maladie intestinale inflammatoire chez tous les mammifères; le traitement consistant à utiliser des 3-(4-pipéridinyl)indoles substitués qui sont des modulateurs du récepteur CCR5. En outre, étant donné que des cellules CD8+ T sont impliquées dans la broncho-pneumopathie chronique obstructive ("MPCO"), le CCR5 peut jouer un rôle dans leur recrutement et par conséquent des antagonistes à CCR5 pourraient constituer un moyen thérapeutique potentiel dans de traitement de MPCO. De même, étant donné que CCR5 est un corécepteur pour l'entrée du virus d'immunodéficience humaine ("VIH") dans les cellules, des modulateurs du récepteur peuvent être utiles dans le traitement de l'infection à VIH.
Patent CA-2305909-A1 (CA)
Inventor: WYSOCKI EDWARD H
IPC: B65F1/02
Filed: 2000-04-17
Abstract: The invention relates to a waste container of the type typically used in residential waste collection systems. The waste container includes a container body having opposing side walls that extend upwardly from a bottom wall to form a waste compartment with an open top for access thereto. The bottom wall of the container body is reinforced by a series of corrugations to increase the rigidity of the bottom wall to prevent sagging, which can result in premature wear and failure. The corrugations also increase the heat transfer rate of the bottom wall, which improves the cooling characteristics of the waste container during molding. The corrugations further provide airflow channels for the injection of air between the container body and a mold during the molding process to improve the ease of removing the waste container body from the mold and to prevent stretching in the bottom of the container during the molding process.

Title: Kcnq2 and kcnq3-potassium channel genes which are mutated in benign familial neonatal convulsions (bfnc) and other epilepsies
Inventor: CHARLIER CAROLE
IPC: C12Q1/68
Filed: 1998-10-23
Abstract: Generalized idiopathic epilepsies (IGE) cause 40 % of all seizures and commonly have a genetic basis. One type of IGE is Benign Familial Neonatal Convulsions (BFNC), a dominantly inherited disorder of newborns. A submicroscopic deletion of chromosome 20q13.3 which cosegregates with seizures in BFNC family has been identified.  Characterization of cDNAs spanning the deleted region identified a novel voltage-gated potassium channel, KCNQ2, which belongs to a new KCNQ1-like class of potassium channels. Nine other BFNC  probands were shown to have KCNQ2 mutations including three missense mutations, three frameshifts, two nonsense mutatations, and one splice site mutation. A second gene, KCNQ3, was found in a separate BFNC  family in which the mutation had been localized to chromosome 8. A missense mutation was found in this gene in perfect cosegregation with the BFNC phenotype in this latter family. This demonstrates that defects in potassium channels can cause epilepsy.  Furthermore, some members of one of the BFNC families with a mutation in KNCQ2 also exhibited rolandic epilepsy and one individual with juvenile myoclonic epilepsy has a mutation in an alternative exon of KCNQ3.

Title: Selection of positioning handover candidates based on angle
Inventor: KINGDON CHRISTOPHER H
IPC: H04W64/00
Filed: 1998-10-28
Abstract: A telecommunications system and method for determining optimal target Base Transceiver Stations (BTSs) to perform positioning handovers and obtain positioning data is disclosed. When a positioning request is received by a Base Station Controller (BSC) serving the Mobile Station (MS) to be positioned, the serving BSC accesses a database within the BSC, which contains a list of cells belonging to candidate target BTSs. Based on this information, and the main antenna direction of the serving BTS, two candidates for positioning handovers are selected from the list such that the angle between the main direction of two adjacent BTSs is nearly equivalent to the angle between the main direction of two additional adjacent BTSs. By selecting the target BTSs in this manner, it can be ensured that the target BTSs surround the MS, thus decreasing the error in the location calculations performed by a Positioning Center (PC).
