Patent CA-2242392-A1 (CA)
Inventor: SCHENK JOHANNES-LEOPOLD
IPC: C21B13/00
Filed: 1997-11-05
Abstract: In a process for producing liquid pig iron (9) or semifinished steel products from finely divided iron-containing materials (4) in a melting gasifier (1), the iron-containing materials (4) are molten in a bed of solid carboncontaining materials (2) to which carbon-containing materials (2) and oxygencontaining gas are supplied, at the same time as a reduction gas is generated. The finely divided reduced materials (4) and the oxygen are laterally introduced into the bed (20, 21). To enable the finely divided iron-containing materials to be introduced into the melting gasifier (1) without being previously briquetted and thus to prevent the finely divided iron-containing materials (4) from being discharged by the reduction gas generated in the melting gasifier (1), a fluidised bed (21) of finely divided solid carboncontaining materials (2) and finely divided iron-containing reduced materials (4) is created above a solid bed (20) of solid carbon-containing materials (2). The finely divided reduced materials (4) are brought directly into contact with oxygen in the fluidised bed (21), preferably in the form of a jet having a ring-shaped cross-section which surrounds the periphery of a jet of oxygen, so that the oxygen is surrounded by the supply of finely divided reduced materials (4), which are then molten in the fluidised bed.
Patent CA-2243303-A1 (CA)
Inventor: BORTOLINI EDWARD J
IPC: H04Q3/00
Filed: 1998-07-16
Abstract: A switching network having a plurality of independent switching units with each switching unit switching one bit of each group of data from external data links through a telecommunication switching system. The plurality of switching units is greater than the number of bits that must be switched which increases reliability. This allows the extra switching units to be utilized as replacement switching units should a switching unit actively switching a bit of the incoming data be disabled. The switching units provide full broadcast switching of data from any individual external link to any number of the other external links. A plurality of port units terminate the external links, and a plurality of controlpaths are provide from a central controller to each of the port units. Each of the switching units communicated one of the control paths. For control, each port unit determines a set of control information that is identical from a majority of the control paths.

Patent CA-2246672-A1 (CA)
Inventor: BOOTH ROBERT THOMSON
IPC: G01W1/14
Filed: 1998-09-21
Abstract: An object of the invention is to provide accuracy as well as simplicity, which is necessary when determining the time of rainfall events after the application of many pesticides. In agricultural and horticultural pesticide applications many chemicals require a rain-free period of 2-6 hours. Often it is common for the applicator to live many kilometers from the spray site. Rainfall patterns are irregular and it is quite difficult to know if a treated area received the adequate rain free period. What commonly occurs when there is doubt as to the time of a rain event, the area in question receives treatment again. This is common in the industry." The simplicity of the RainFall Timer enables it usable to pesticide applicators who require a simple reliable device to inform them of the timing of rain events to accurately base their decisions to respray or not.

Patent CA-2267872-A1 (CA)
Inventor: CHATMAN GARRY B
IPC: B64F5/20
Filed: 1999-03-25
Abstract: In a world of modern technology millions of people worldwide travel daily by air to destinations both near and far.        In North America, as well as various European locations including the Scandinavian countries, winter weather is both an annual cycle and a challenging threat.      Each year dozens of airports throughout the Northern Hemisphere millions of litres of de-icing fluids mainly Glycol of various types, are used in order to de-ice aircraft for safe and successful take-off.     This de-icing fluid is very expensive and somewhat less than environmentally friendly. Various airport commissions and environmental groups have on numerous occasions voiced concern regarding de-icing fluid runoffs into the soil and nearby streams and rivers. And eventually even into water tables, etc.   For many years aircraft have had their interiors heated before the boarding of passengers via a large hot air duct being run from a portable heater unit of several types and designs.   After testing various mechanical possibilities in and around various aircraft at major airports my co-inventor and I, being employees of a major airline, have come up with a rather unique adaptation.   An adapter type unit when connected to an existing heater or heaters which were sole designed to supply heat to the interior of parked aircraft.   This adapter when connected to the existing heater unit can produce enough heat and hot air to melt frost, ice, or snow from the propellers of an aircraft and at the same time blow it away. This invention in future will find use in de-icing other aircraft surfaces, such as wings, tail, landing gears, fuselages, and thawing frozen jet engines.    The main purpose of this apparatus is to successfully reduce the gross use of glycol and other type fluids which can be harmful to the environment.

Abstract: L'invention concerne un procédé en deux étapes, modifiable, d'identification de la (des) fonction(s) cellulaire(s) d'un ou de plusieurs gènes à fonction inconnue, et d'identification de modulateurs de ce (ces) gène(s). Dans ce procédé on utilise l'inversion ou l'altération d'un phénotype créé par l'expression d'un gène hétérologue, par exemple un gène humain, afin d'identifier des modulateurs de cette activité du (des) gène(s). On utilise ensuite ce modulateur dans un système de modèle de maladie in vitro ou in vivo, afin d'identifier des composés affectant la progression d'une maladie. La sous-population de composés qui exercent une influence thérapeutique sur une maladie constitue des chefs de file d'une famille de médicaments. Cependant, tous les composés influençant la progression d'une maladie constituent des outils destinés à au moins caractériser partiellement une fonction génique. L'étape du procédé d'identification de l'inhibiteur s'effectue, de préférence, au moyen de plusieurs souches ou lignées cellulaires microbiennes exprimant différentes séquences d'ADN hétérologues, dans une seule solution. Ce procédé est notamment utile pour des gènes qui n'ont pas été validés comme de bonnes cibles d'inhibiteur.
