Patent CA-2159901-C (CA)
Inventor: LABRANQUE GILLES
IPC: F25B17/08
Filed: 1994-04-05
Granted: 2002-10-01
Abstract: A reagent (26) combines exothermically with a cold refrigerating fluid exiting a refrigerating evaporator during a refrigeration cycle, then releases said fluid once it has been heated to a high enough temperature by a heater (17) during a regeneration cycle in which the refrigerating fluid condenses in a pressurised enclosure. The reagent is enclosed in stainless steel walls (29, 31, 34) which prevent it from swelling and include perforated tubes (34) arranged around channels (32) enabling masses to be exchanged during the combining and separating reactions. The heater (17) is arranged in a central housing (46). An air flow (54) which is cutt off during regeneration carries off the heat from the combining reaction by means of fins (56). Deformation and gradual deterioration of the reagent block over repeated cycles until it becomes useless are thus prevented.

Abstract: L'invention concerne un récepteur à large bande pour la mesure de distance par signaux de code pseudo-aléatoires. Ce récepteur comporte un traitement de signal utilisant la corrélation du signal composite reçu avec des codes pseudo-aléatoires générés localement, avancés/retardés. Le générateur de code (580) envoie ses signaux à une ligne à retard (582) dont les sorties régulièrement espacées (E2, E1, P, L1, L2) sont combinées selon la relation C = E2-2E + 2L1 - L2 avant d'être envoyées à un des corrélateurs (C2), tandis que l'autre (C1) reçoit le signal ponctuel (P). Ceci réduit notablement l'erreur de position due aux retards de trajet multiple. L'invention s'applique notamment aux récepteurs des systèmes GPS ou GLONASS.

Title: Absorbent gelling material comprising a dry mixture of at least two types of hyrogel-forming particles and method for making the same
Inventor: SCHMIDT MATTIAS
IPC: A61F13/15
Filed: 1995-07-03
Granted: 2000-03-14
Abstract: By mixing two types of hydrogel-forming particles having different Absorption Against Pressure values, a synergistic effect can be obtained wherein the AAPvalue of the mixture is higher than would be expected on the basis of the weight fractions of the components of the mixture. By mixing two types of hydrogel-forming particles having different Teabag Centrifuge Capacity values and equal AAP values, an unexpected increase in the AAP value of the mixture is observed. A method of manufacturing the absorbing gelling material according to the invention comprises the steps of: providing a first type of hydrogel-forming material and a second type of hydrogel-forming material; introducing both types of hydrogel-forming material in a mixing means; and mixing both types of hydrogel-forming particles to form the mixture. Both types of hydrogel-forming material may be formed by a separate polymerisation process in separate batches, followed by mixing the two types of hydrogelforming particles. Alternatively, a weight fraction of a single type of hydrogel-forming material may be separated from the bulk of the material, may subsequently be treated to increase the AAP value thereof, and may be mixed back into the bulk material.

Title: Method of monitoring radiation using a floating gate field effect transistor dosimeter, and dosimeter for use therein
Inventor: TARR NICHOLAS GARRY
IPC: G01T1/24
Filed: 1997-09-12
Granted: 2008-11-18
Abstract: An insulated gate field effect transistor dosimeter has a source and drain defining a channel region, a floating gate having a first portion extending over the channel region, and a second, larger portion extending away from said region, a control gate having at least a portion thereof overlapping a first part of the floating gate, and a charging gate overlapping a second part of the floating gate. The area of the second part of the floating gate is much smaller than the area of the first part, and the charging gate is separated from the channel region by the control gate. The dosimeter is charged, before irradiation, by connecting the source, drain and control gate to a common ground and applying a potential difference between the charging gate and the common ground. The charge is supplied to the floating gate by a path which does not require a significant electric stress to be created in the region of the gate oxide and the channel. The dosimeter may comprise two such transistors fabricated on a common substrate, conveniently with a common source. The pair of transistors may be charged by maintaining the sources, drains and control gates within the normal maximum operating voltage relative to each other, and applying different potential differences between the two charging gates, respectively, and the substrate. Following irradiation, the absorbed radiation dose is determined by measuring the difference between the threshold voltages of the two transistors. Preferably, the transistors have charges of opposite polarities. This differential arrangement reduces the effects of temperature variations and enhances sensitivity.

Abstract: The combat communication system is used for "identification friend or foe", firing simulation during practice, and/or combat aiming for live night shooting. Each participant wears a harness comprising light detectors and control units, as well as a laser assembly mounted to a weapon. For firing simulation or identification, a participant aims his weapon at a potential target and sends a laser signal. When the target is another participant wearing a harness, his harness answers via a radio, ultrasonic or light signal. The carrier frequency of the response signal can be determined and transmitted by the querying unit over the laser beam.

Granted: 2001-02-13
Abstract: The present invention provides a method of controlling NO x emissions from a glass melting process in which combustion fuel produces exhaust gas in a melting furnace including NO x compounds. Furnace exhaust gas passes from the melting furnace through a regenerator to a zone downstream from the regenerator. Ammonia is injected into the furnace exhaust gas at the downstream zone while the furnace exhaust gas is within a desired temperature range to reduce the amount of NO x compounds. Additional gas is introduced into the furnace exhaust gas as it moves from the regenerator to the downstream zone whenever the furnace exhaust gas has a temperature which is outside the desired temperature range at the downstream zone so as to modify the furnace exhaust gas temperature such that the furnace exhaust gas is within the desired temperature range when furnace exhaust gas reaches to the downstream zone. In one particular embodiment of the invention, the additional gas is the exhaust from an excess air burner which is injected into the furnace exhaust gas at a temperature such that the furnace exhaust gas and the injected gas have a combined temperature between about 870 to 1090°C at the downstream zone.
