Title: Dispositif filtrant pouvant pieger une quantite de matiere desiree, et procedes d'utilisation
Inventor: FERGUSON GARY W
IPC: G01N1/40
Filed: 2003-09-17
Abstract: La présente invention concerne un dispositif filtrant et des procédés pour piéger une quantité désirée de matière en suspension dans un liquide ou un gaz. Ces procédés de piégeage par filtre peuvent être utilisées pour l'épuration ou l'enrichissement de divers constituants d'échantillons, ou des matières piégées peuvent être observées ou analysées. En variante, une matière particulaire peut être utilisée comme mécanisme de transport de protéines ou de substances chimiques, lesquelles peuvent à leur tour être évaluées ou utilisées. Le dispositif filtrant utilise des moyens de détection de pression, et réagissent donc à des oscillations de pression associées au débit de l'échantillon en suspension passant au travers du filtre, généralement à une pression préétablie associée au piégeage d'une quantité désirée de la matière sur le filtre. De plus, le dispositif filtrant utilise un moyen d'arrêter ou autrement de réguler le débit de l'échantillon lorsque ladite pression préétablie est détectée.

Abstract: BACTERIAL DETECTION BY PHAGE TRANSDUCTION OF DETECTABLE PHENOTYPE      Abstract of the Disclosure Viable bacteria may be detected in biological samples by exposing bacterial cultures obtained from the samples to transducing particles having a known host range.  Such transducing particles carry a heterologous gene capable of altering the phenotype of the bacteria in a readily detectable manner.  For example, the transducing particles may carry an ice nucleation gene and the alteration of phenotype may be detected using an ice nucleation assay.  By employing a panel of phage, unknown bacteria may be typed based on the pattern of reactivity observed.     C:\WORK\PAT\121766-1.JMH

Title: Method of examining an optical component and arrangement therefor
Inventor: KUCHEL MICHAEL
IPC: G01M11/02
Filed: 1989-10-26
Abstract: Abstract of the Disclosure The invention is directed to a method for testing optical components and tests can be made on aspherical surfaces or, more specifically, on aspherical wavefronts.  For this purpose, the collimator of an interferometer which generates the test wave is displaced relative to the test component and interferograms are electronically registered by means of an image sensor in different positions of the collimator and are stored as light path length differences between the test beam and the comparison beam for the individual image points of each interferogram.  The relative position between the collimator and the test component is additionally measured with high precision.  Thereafter, the light path length differences which were measured interferometrically are compared with desired light path length differences computed for the different positions of the collimator or determined by calibration.  From this comparison, the aspheric form of the wavefront of the test component is computed.  For this computation, the measured values obtained for the different component regions of the test component are integrated over the entire surface of the test component with the measured regions being those wherein the test wave falls essentially perpendicularly onto the surface of the test component.

Title: High-efficiency furnace for mobile homes
Inventor: VAUGHN THOMAS D
IPC: F24H8/00
Filed: 1990-03-28
Abstract: HIGH-EFFICIENCY FURNACE FOR MOBILE HOMES                   ABSTRACT OF THE DISCLOSURE    A furnace utilizing, in the upper portion of its cabinet, a blower acting downward through a separator opening to circulate room air past a combustion chamber whose gases flow upward through a sideward-positioned broad radiator member which reaches up to the flue.  A substantial increase in efficiency results from drawing the combustion gases out of the combustion chamber at the side opposite to the lower end of the broad radiator mem-ber, and interposing therebetween, directly beneath the separator opening, a plurality of tubes which serve as an intermediate heat exchanger.  A still greater increase in efficiency is achieved by utilizing, instead, a finned tube heat exchanger across and be-neath said separator opening; its heat transfer may be so great as to result in condensation of water vapor in the combustion gas.  To purge this, a motorized inducer-blower is used in the inlet air system, driving the condensate through the finned tube heat exchanger to an appropriate drain.

Patent CA-2018502-A1 (CA)
IPC: H01S5/14
Filed: 1990-06-07
Abstract: ABSTRACT      Integrated  semiconductor  structure with optically coupled laser diode and photodiode, both devices having etched, vertical facets. The photodiode has a spatially non-uniform  sensitivity  profile  with  respect  to  the incident light beam emitted by the laser. This is due to the varying distance  from the  laser  facet  and/or  to variations  in  the  angle  of  incidence  and  results  in photocurrents produced by the photodiode that depend on the  intensity  distribution  of  the  light  beam.  The spatially  non-uniform  sensitivity  profile  allows  the measurement of the far-field intensity distribution of the laser and thus on-wafer  screening of  lasers with respect to their mode-stability.

Title: Method for excavating rock cavities

IPC: E21D13/02
Filed: 1990-12-05
Abstract: ABSTRACT            The present invention relates to a method for ex-cavating substantially spherical rock cavities or rock cavities having spherically shaped parts, such as dome-shaped ceilings.          A first series of radially outwardly extending holes is drilled from a first distance from one or more shafts/tunnels preferably radially arranged from the centre of a sphere.  A second series of radially outwardly extending holes is drilled from a second distance arranged further from the centre, the second holes extending beyond the holes of the first series.  A third series of radially outwardly extending holes is then drilled from a third distance arranged still further from the centre.  The third holes extending beyond the second holes. Optionally further series of holes may be drilled from further locations still further removed from the centre in an analogous fashion.   The first series of holes is charged along their whole lengths and each further series of holes is charged in that part which lies outside a charging area of a previous series of holes up to the touching point of a next series of holes.  In this way, the charges will take consecutive annular charging areas, which cover the shape of the spherical cavity projected, and that blasting takes place only in each annular area.

Title: Frame synchronization system among multiple radio base stations for tdma digital mobile communications system
Inventor: KONDO SEIJI
IPC: H04J3/06
Filed: 1990-12-27
Abstract: A TDMA digital mobile communications system prevents TDMA frame synchronization from being asynchronous among radio base stations when a communication held by a mobile station is handed over from one service area to another.          A control station sends a reset pulse for TDMA frame synchronization to the radio base stations each being situated in a particular service area over communications cables.  In response, the radio-base stations each generates a TDMA frame.  The control station has a synchronous signal generator for generating the reset pulse while each radio base station has a time delay adjustment unit for adjusting the time delay of the reset pulse.  The synchronous signal generator and the time delay adjustment units of the individual radio base stations perform measurement and setting such that a reset signal has the same time delay between the control station and all of the radio base stations.  Hence, regarding a TDMA signal which the mobile station receives, TDMA frame synchronization is immediately set up at the time of hand-over and thereby prevents a voice signal from being interrupted.
