Patent CA-2310298-A1 (CA)
Title: Method of three dimensional laser engraving
Inventor: WILLIAMS MARK S C
IPC: B44C1/22
Filed: 2000-05-31
Abstract: A method for laser engraving a three-dimensional image into a workpiece includes providing a plurality of pieces of artwork which form a composite three-dimensional image. Each piece of artwork corresponds to a particular layer of material to be removed from the workpiece. The pieces of artwork are sequentially read by laser system program software which translates the lines on each piece of artwork into signals corresponding to laser paths. The signals are received by the laser system control assembly for directing the laser beam along the workpiece in a layer-by-layer relationship corresponding to the sequentially read pieces of artwork. The use of the plurality of pieces of artwork allows for a layer-by-layer removal of material in the workpiece such that the power of the laser need not be continuously adjusted according to the depth of penetration into the workpiece. The method allows for various engraved images to be presented having various sloped surfaces therein.

Title: Event broadcasting system for the blind in concert halls and other areas
Inventor: GOMEZ BORRALLO JUAN JOSE
IPC: G09B21/00
Filed: 2000-07-28
Abstract: An even broadcasting system in concert halls intended to be used by the blind permitting them to enjoy shows by the narration of images and scenes, as well as providing information in other places to guide them safely. The system has a device (CD, DVD, mini-disc. etc.) where the information that should reach the user is recorded. This reader sends the information to an infrared amplifier that processes the audio signal, transforms it into an infrared signal and amplifies it to be transmitted to one or more infrared transmitters. The waves transmitted by the transmitter are captured by the user's receiver converting them into sound to be broadcast through the headset. In the case of shows, the narration is perfectly synchronised with the original film sound track, using the dead spaces for such a purpose and hence avoiding companions' dialogues in the cinema or theatre.

Title: Process for pyrolysing carbonaceous feedstocks
Inventor: NIEMINEN JUKKA-PEKKA
IPC: C10B53/00
Filed: 1999-02-26
Abstract: The present invention concerns a process and an apparatus for thermal conversion of biomass and organic wastes. According to the invention the feedstock is fed into a fluidized-bed reactor (1-3), wherein the feed is converted at an elevated temperature under the influence of particulate matter kept in a fluidized state by a fluidizing gas, the particulate matter is transferred from the reactor to a regenerator (24, 28, 29) for regeneration and then recirculated to the reactor after the regeneration, and the converted hydrocarbon products are recovered from the reactor. Both the reactor (1-3) and the regenerator comprise risers (13, 24) having an axially annular cross section and being equipped with multi-inlet cyclones (14, 17, 25, 26) for the separation of particulate matter. By means of the invention it is possible to produce pyrolysis oil, the quality of which is higher than that of oil produced with the processes of the prior art. The incorporation of multi-inlet cyclones into the reactor configuration reduces gas velocities, reduces the physical size of the cyclone and shortens the residence time of gases in the cyclone.

Title: Improved method of solid state welding and welded parts
Inventor: LINGNAU DAVID
IPC: B23K13/00
Filed: 1999-11-01
Abstract: A method of solid state welding for joining metal parts having opposed planar and parallel surfaces which includes quickly heating the opposed surfaces of the metal parts with a high frequency induction heater to the hot working temperature of the metal parts in a non-oxidizing atmosphere, continuously moving at least one of the parts relative to the other part generally parallel to the parallel surfaces of the parts, and quickly bringing the opposed surfaces of the parts together with an axial force approximately equal to the conventional friction welding forging force while continuing the relative motion of the parts until the absorbed kinetic energy is approximately equal to ten percent of the energy input required by conventional friction welding. The resultant weld is of a quality equal to or greater than normal friction welding but has a much smaller volume of flash and requires significantly less kinetic energy than conventional friction welding and is performed at rotational velocities well below the normal critical surface velocity of friction welding.  The welded metal part includes a generally planar flash extending radially from the inner section of the opposed planar welded surfaces having a volume corresponding to a combined loss of length of less than 0.2 axial inches per inch of wall thickness. Thus, the disclosed solid state welding method is substantially more efficient than prior friction or other welding methods and results in an improved product.
