Patent CA-2251627-A1 (CA)
Title: Thermally enhanced compact reformer
Inventor: HOAG ETHAN D
IPC: H01M8/24
Filed: 1997-03-25
Abstract: A natural gas reformer (10) comprising a stack of thermally conducting plates (12) interspersed with catalyst plates (14) and provided with internal or external manifolds for reactants. The catalyst plate is in intimate thermal contact with the conducting plates so that its temperature closely tracks the temperature of the thermally conducting plate, which can be designed to attain a near isothermal state in-plane to the plate. One or more catalysts may be used, distributed along the flow direction, in-plane to the thermally conducting plate, in a variety of optional embodiments. The reformer may be operated as a steam reformer or as a partial oxidation reformer. When operated as a steam reformer, thermal energy for the (endothermic) steam reforming reaction is provided externally by radiation and/or conduction to the thermally conducting plates. This produces carbon monoxide, hydrogen, steam and carbon dioxide. When operated as a partial oxidation reformer, a fraction of the natural gas is oxidized assisted by the presence of a combustion catalyst and reforming catalyst. This produces carbon monoxide, hydrogen, steam and carbon dioxide. Because of the intimate thermal contact between the catalyst plate and the conducting plates, no excessive temperature can develop within the stack assembly. Details of the plate design may be varied to accommodate a variety of manifolding embodiments providing one or more inlets and exit ports for introducing, pre-heating and exhaust the reactants.

Title: Method for copy protecting a record carrier, copy protected record carrier and means for detecting access control information
Inventor: NEWMAN PETER ALFRED
IPC: G06F1/00
Filed: 1998-05-25
Abstract: A method for copy protecting a record carrier is disclosed, in which method the copy protected record carriers are provided with a pattern of logical errors which cannot be corrected by the error correcting rules predefined for said record carrier. The pattern of logical errors represents access control information. The logical errors are generated during decoding the bit sequence read from the record carrier. Bit errors may be positioned in the bit sequence so as to counteract de-interleaving which is part of an error decoding process in a reading device and accumulate in error words which are uncorrectable.  Also a method for detecting access control information and a retrieval arrangement are disclosed, which retrieval arrangement serves to detect the access control information by selecting at least one error location, but not all error locations on the record carrier, and verifying the presence of an error by reading the selected error location via the reading means.

Patent CA-2271282-A1 (CA)
Inventor: GRAEBNER JOHN EDWIN
IPC: H01L41/187
Filed: 1999-05-06
Abstract: The invention provides a device comprising an oriented, perovskite PZT layer on a diamond substrate, or other substrates such as silicon or platinum-coated materials. Vapor phase deposition processes are used to deposit a PZT layer onto a perovskite template layer on the substrate. The template layer is more readily deposited in a perovskite structure compared to PZT, and provides for nucleation and growth of the deposited PZT in perovskite form. The vapor phase deposition promotes the oriented structure of the resulting film. The structure is useful in a variety of devices, including surface acoustic wave devices.

Abstract: A method and apparatus are disclosed for protecting the weld area of polyolefin coated steel pipe with an epoxy-based coating. The epoxy-based coating adheres well to the metal of the pipe, but does not adhere well to the polyolefin pipe coating. An intermediate bonding material therefore is applied to that portion of the polyolefin pipe coating which will be overlaid by the epoxy-based coating, prior to applying the epoxy based coating. The intermediate bonding layer selected is one which will adhere satisfactorily to the metal of the pipe, to the materials of the polyolefin coating and to the epoxy-based coating.
