Filed: 1999-11-23
Abstract: A process for converting natural gas to a liquid includes heating the gas to a selected range of temperature to convert a fraction of the gas stream to reactive hydrocarbons, primarily acetylene, and reacting methane and the reactive hydrocarbons in the presence of an acidic catalyst to produce a liquid, predominantly pentane. Hydrogen resulting from the reactions is used to heat the incoming natural gas, either with a hydrogen furnace or by electrical energy generated from the hydrogen.  Little or no use of methane is required to supply energy for the process.

Patent CA-2362692-A1 (CA)
Inventor: TICHBON WAYNE
IPC: C01F7/473
Filed: 2000-03-17
Abstract: A process for the removal and causticisation of sodium oxalate and/or sodium sulphate from a Bayer process liquor containing sodium carbonate and one or both of sodium oxalate and sodium sulphate in an alumina refinery is described. The process is based on the observation that to efficiently causticise sodium oxalate solutions, it is first necessary to remove the aluminate ion from solution, optionally with recovery of the aluminate ion in some later step. This is effected by removing aluminate ions from the Bayer liquor through the formation of a carbonate-bearing hydrocalumite and/or sulphate-bearing hydrocalumite. The liquor may then be treated with sufficient lime to remove and causticise any residual carbonate ions and some or all of the oxalate ions present so that any reacted lime solids thus formed can be separated and safely disposed of. The process may include a pre-causticisation step in which the Bayer liquor is first causticised to reduce the concentration of carbonate ions, prior to the step of removing aluminate ions. The invention provides an effective process for the removal of sodium sulphate and a practical method for the recovery of soda from sodium sulphate. The efficiency of lime utilisation can also be dramatically increased from about 20 % to 80 % (if sulphate removal is not the objective) wherein alumina losses can be minimised. The oxalate concentration of the process liquor is also substantially lower than can usually be achieved in processes based on sodium oxalate-crystallisation.

Abstract: A ceiling tile antenna for use in wireless local area networks and voice networks. A patch style antenna is manufactured in which the dielectric substrate is the ceiling tile itself, and the radiating element and the ground plane are fixed to the face and back of the tile, respectively. Since the ceiling tile acts as the antenna, the back of the ceiling tile does not have to be routed out to create a cavity for an antenna pod. The sizes of the radiating element and the ground plane are not an issue; therefore no miniaturization of the elements is required.  Compared to microstrip antennas, a ceiling tile antenna provides a wider bandwidth and higher gain due to the thicker dielectric substrate used for the ceiling tile construction.  Therefore, it is easier to achieve multiple resonances. The ceiling tile used as an antenna can be made from mineral fiber, medium density fiber board, fiberglass, drywall and polyvinyl chloride.
