Title: Method and apparatus for clarifying and/or thickening a slurry
Inventor: NUORALA MATTI
IPC: B01D21/24
Filed: 2002-06-19
Abstract: The invention relates to a method of clarifying and/or thickening a solution containing solids i.e. a slurry, and the apparatus for accomplishing this. Using the method and apparatus of the present invention, the slurry to be fe d into the clarification or thickening apparatus is distributed evenly into th e slurry already in the tank. It is characteristic of the clarification tank n ow developed that the displacement capacity of the raking system in the tank is the same from the edges of the tank up to the centre. The displacement capacity is measured as being the same as the underflow discharge capacity from the centre of the tank. The displacement capacity can be determined to be the same using rake displacement plates of different heights, according to t he distance of the displacement plates from the rake shaft and the number of plates rotating on the same ring-like cross-section.

IPC: B66B13/14
Filed: 2003-12-17
Abstract: A control system for a motorized freight elevator landing door in which all of the doors in a single line of a hoistway are controlled with one set of proximity sensors carried on the elevator car. The sensors signal a controller that operates electric motors for opening and closing the landing door where the car has stopped. The door operating motors are two speed units and the sensors and controller are arranged to operate the motors at high speed during most of the travel in opening or closing movement and at reduced speed at the end of movement. The controller applies power to the motor for a short period after the door is fully closed or open to stall the motors and thereby dampen any rebound motion.

Abstract: L'invention porte sur une protéine chimère comprenant un domaine catalytique redox provenant d'une source et un domaine de transfert d'électrons provenant d'une source différente. Ladite protéine s'utilise dans un procédé dans lequel le substrat du domaine catalytique redox étant actionné, les électrons sont transférés entre le domaine catalytique redox et le domaine de transfert d'électrons et entre domaine de transfert d'électrons et une électrode. On peut suivre le courant ou le potentiel de l'électrode pour déterminer la présence ou la quantité d'un substrat constituant un analyte d'intérêt. En variante, le courant peut être tiré de l'électrode pour provoquer la réaction du substrat, par exemple pour détoxiquer des échantillons. Le domaine catalytique redox pourra dériver d'un cytochrome P450, et le domaine de transfert d'électrons peut être une flavodoxine.

Filed: 2004-02-10
Abstract: A data reception method, an apparatus implementing such a method, and a data transmission system are disclosed, in which appropriate evaluation levels for signal levels are set during initialization of data communications using small circuitry. A comparator 574 compares a difference value dd against its corresponding model value. If the difference value dd is greater than the model value, the comparator 574 updates one of registers 576a to 576n which is currently selected, by adding a predetermined numeric value to the model value. If the difference value dd is smaller than the model value, the comparator 574 updates one of the registers 576a to 576n which is currently selected, by subtracting a predetermined numeric value from the model value.      An evaluation level value arithmetic circuit 572 calculates evaluation levels R1 to R13 using model values set in the registers 576a to 576n, and stores the evaluation levels R1 to R13 respectively to registers 577a to 577m of an evaluation level storage section 573.

Title: Polymorphisms associated with ion-channel disease
Inventor: CURRAN MARK EDWARD
IPC: C12Q1/68
Filed: 2002-08-20
Abstract: The present invention provides methods and materials to identify genetic abnormalities that predispose an individual to ion-channel diseases. The invention provides four polymorphic sites in the KCNQ1 gene that cause reduced conductance of the associated potassium ion channel current and a variant form of the KCNE1 gene which causes decreased conductance though the channel. The variant form of KCNE1 also acts synergistically with variants of KCNQ1 to cause further decreased conductance than either variant alone. The invention further provides polymorphisms in ion channel genes showing a higher frequency in populations afflicted with ion channel diseases or within control groups.  The detection of these polymorphic sites that produce the potassium ion channel protein variants in either heterozygous or homozygous form in a subject indicates that the subject has, or is susceptible to, ion channel diseases such as congenital or acquired cardiac arrhythmia, LQT syndrome, SIDS, epilepsy, or hearing loss.
Patent CA-2457447-A1 (CA)
Inventor: BROOKS PAUL D
IPC: H04N21/61
Filed: 2002-07-31
Abstract: In a hybrid fiber coax (HFC) cable system (20), data is communicated upstream from user terminals (100) to a headend (240) of the system (20) to realize various interactive services. The user terminals (100) generate analog modulated signals representing the user data, which populate different channels in a reverse passband of the system. In accordance with the invention, the analog modulated signals are transformed to the corresponding digital baseband signals containing the data. The resulting digital baseband signals are optically transmitted to the headend (240), thereby efficiently utilizing the limited capacity of the fiber optical portion of the HFC cable system (20).
