| 20110303676 | SHEET METAL EXPLOSION-PROOF, AND FLAME-PROOF ENCLOSURES - An explosion retaining housing includes a sheet metal member or outer skin which at least in part forms an interior region of the housing. At least one structural element provides additional strength to the member to retain the explosion in the region. The structural element can be inside of, or, outside of the region. The structural element can have a plurality of components which cooperate together to resist the force of an explosion in the interior region. | 12-15-2011 |
| 20110302991 | THERMALLY INSULATING CERAMIC SUBSTRATES FOR GAS SENSORS - A gas sensor includes a substrate having a low thermal conductivity. Localized heating can be produced using a serpentined heater carried by the substrate. The low thermal conductivity of the substrate substantially confines the generated heat to a region local to the heater thereby reducing required power to operate the sensor. Multiple sensing elements can be deposited onto the substrate adjacent to respective heaters and relatively close together because of the thermal isolation provided by the substrate. In one embodiment, the sensor can include the ceramic substrate, the heater, catalytic material overlying the heater with a gas impermeable layer overlying, at least in part the catalytic material. | 12-15-2011 |
| 20110005927 | Electro-chemical Cell and Method of Providing Multiple Electrical Connections to a Lead Anode of an Electro-chemical Gas Sensing Cell - A lead wool electrode for an electro-chemical cell can be fused to a metallic collector to provide an electrical connection therebetween. Various methods of fusion such as thermal, electrical or chemical can be used. | 01-13-2011 |
| 20100288652 | APPARATUS AND METHOD OF REGENERATING ELECTROCHEMICAL GAS SENSORS - A method of improving performance of electrochemical gas sensors includes cycling potentials applied to one or more of the electrodes of the respective sensor(s) to improve performance of a different electrode. In a process for treating a reference electrode, potentials can be applied to working and, or counter electrodes so as to modify the environment in the vicinity of the reference electrode. An apparatus can carry out the method automatically. | 11-18-2010 |
| 20100212395 | Instrument Docking Station with Non-Destructive Sensor Analysis Capabilities - A docking station for use with gas sensors includes limited test and diagnostic circuitry directed to specific characteristics of selected detectors. Where a family of detectors is to be evaluated, a universal interface for that family can be included. A single port can be used for multiple different detectors irrespective of specific detector characteristics. | 08-26-2010 |
| 20100170795 | ELECTROCHEMICAL GAS SENSOR - An electrochemical gas sensor has a hollow housing with multi-layer walls. A first layer of the walls has a selected water vapour transport rate. A second layer of the walls has a lower water vapour transport rate than the selected rate. The housing can be formed by first and second moulding processes. | 07-08-2010 |
| 20090120794 | Gas Sensor - The present invention provides a unique solution to the problems of both steady-state and transient signals produced by a variety of interfering stimuli, including humidity, which relies upon the inclusion in a gas sensing electrode in an electrochemical gas sensor of a catalyst material, in addition to a first catalyst material reactive to the target gas, the additional, or second, catalyst material producing a response to an interfering stimulus which is of the opposite polarity to that generated by the first catalyst material. | 05-14-2009 |
| 20090057150 | ELECTROCHEMICAL GAS SENSOR - An electrochemical gas sensor is disclosed which comprises a gas sensing electrode and a counter electrode disposed within a housing, the housing having an aperture for gas ingress, the gas sensing electrode and counter electrode being separated by a region containing electrolyte, and means for connecting the gas sensing electrode and the counter electrode to a sensing circuit. An electrolyte-absorbing element is disposed inboard of the aperture, between the housing and the gas sensing electrode, in order to absorb electrolyte passing through the gas sensing electrode whilst maintaining a gas path through the electrolyte-absorbing element. | 03-05-2009 |
