Title: Gas burner system
Inventor: SHAW ROBERT KENNETH
IPC: F24C3/00
Filed: 1993-09-20
Granted: 1998-08-04
Abstract: This gas burner system provides an asymmetrical flame pattern together with the presence of glowing embers around and beneath non-combustible logs, closely resembling the overall appearance of a  natural wood  fire  in  a  fireplace.  The  burner  system  has a plurality of gas burner pipes arranged in a fan-out pattern on a log mounting plate to provide gas throughout the logs arranged over the plate. Air supply openings are formed at selected areas in the mounting plate to permit fresh air to pass only therethrough from below the mounting plate to the fire. Air deflectors are located adjacent to the openings and lava rock and/or mineral fibre pieces are placed below the logs over the gas burner pipes to disperse the combustible gas throughout the log arrangement. The provision of openings  and  deflectors  create  air  currents  flowing  over  the surfaces of the logs to prevent the flames from impinging on the log surfaces for  reducing the formation of carbon deposits and carbon monoxide gas.

Patent CA-2162772-C (CA)
Inventor: NAGY BELA G
IPC: B28D5/00
Filed: 1995-11-14
Granted: 1999-06-01
Abstract: A combination measuring and ablation laser apparatus is provided which generally includes an ablating laser, a profilometer laser, an automatic feedback control unit and electro-mechanical positioning apparatus.  The combination measuring and ablation laser apparatus can have a single multi-mode laser having an ablating mode and a measuring mode and a positioning means for positioning the laser between ablating and measuring modes.  According to the method of the invention, the profilometer laser measures the thickness of a diamond sample and compares it to the desired thickness.  Where the measured thickness is too large, the feedback control unit activates the ablating laser for a predetermined time interval to smoothen any irregularities which may be contributing to the diamond sample thickness.  At the end of the time interval, the portion is remeasured by the profilometer laser to determine if it conforms to the desired thickness.  If the portion still fails to conform to the desired thickness, the feedback control unit repeats the steps of positioning and activating the ablation laser to further ablate the portion. This process is repeated until the thickness of the portion is equal or less than the desired thickness, after which the same procedure is used on the rest of the diamond sample until a uniform desired thickness is achieved throughout.

Title: Local communication network for power reduction and enhanced reliability in a multiple node tracking system
Inventor: WELLES KENNETH BRAKELEY II
IPC: B61L25/02
Filed: 1996-05-17
Granted: 2005-08-02
Abstract: A mobile local area network (LAN) of tracked assess utilizing minimal power and bandwidth allows a large number of assets to be tracked in a practical manner. The mobile LAN is established between a plurality of tracking units in close proximity. Assets are approximately located according to their connection in the mobile LAN where the exact location of at least one of the network nodes is known. Each tracked asset has capability to independently determine and report its position to a central station, and each asset also has capability to communicate locally with other cooperative assets via the LAN. The LAN is dynamically reconfigurable so that as other cooperative assets come into proximity, they can join the network, and as others move away, they can leave the network. Within the network, a protocol is followed which assigns one of the assets to be the "master" and all others to be "slaves". The master asset takes responsibility for determining its own exact geographical position via LORAN, OMEGA, Global Positioning System (GPS) or ocher navigational aid. When connected in a LAN, slave assets report their ID to the master asset and do not determine their own locations in order to conserve power. The master reports its location and ID, as well as the IDs of the other assets in the LAN, to the central station. Uncertainty in the location of a slave asset is limited by the known possible geographical extent of the LAN which is known a priori.
