Patent CA-2234277-A1 (CA)
Title: Method of and apparatus for welding workpiece
Inventor: MATSUO KAZUHIDE
IPC: B23K26/08
Filed: 1998-04-02
Abstract: Scanning welding heads are introduced through respective openings of a workpiece into the workpiece by respective welding robots.  When a laser beam is emitted from a laser beam emitting device, the laser beam is applied to a beam splitter of one of the welding robots, which reflects about 50 % of the energy of the laser beam and introduces the laser beam into a scanning welding head.  The beam splitter passes the remaining 50 % of the energy of the laser beam therethrough.  The laser beam that has passed through the beam splitter is reflected by a totally reflecting mirror of another scanning welding head.  The scanning welding heads apply the laser beam to respective regions in the workpiece to weld the workpiece.

Title: Adaptive pre-distortion apparatus for linearizing an amplifier output within a data transmission system
Inventor: DAVIS ROBERT C
IPC: H03G3/30
Filed: 1998-06-19
Abstract: An adaptive apparatus for compensating the non-linear distorting action of an amplifier in a transmission system. I-channel and Q-channel memories store a plurality of digital pre-distortion correction values. The memories are addressed using a predetermined number of significant bits of an incoming, original information signal to retrieve I-channel and Q-channel pre-distortion correction values. The I-channel and Q-channel pre-distortion correction values are combined, digitally, with I-channel and Q-channel components of the original information signal to pre-distort the original information signal. The pre-distorted signal, in real format, is supplied to the amplifier, and a feed-back sample signal is coupled-off of the output of the amplifier.

Title: Disposable microscope slide dispenser
Inventor: MENES CESAR
IPC: B65D83/08
Filed: 1999-02-19
Abstract: A microscope slide dispenser is formed with a slide case dispensing attachment having a slide dispensing mechanism and a disposable, plastic slide case that is removably coupled to the dispensing attachment. Positioning members on the dispensing attachment interact with corresponding members on the case to properly position the slide relative to a seating platform or slide case seat. A slide carrier has a anger that projects outwardly from the dispensing attachment and toward the slide case to engage the rear edge of the closest of a plurality of microscope slides stacked within the case. The case is provided with a carrier finger opening and a slide dispensing slot. Operation of the dispensing mechanism engages the carrier finger behind the slide closest to the end wall at which the dispensing attachment is located. The carrier finger pushes the microscope slide closest to the end wall at which the dispensing attachment is located out of the slide case through the slide dispensing slot. The carrier may be spring-biased so that the slide-engaging finger returns to a slide-engaging position behind the next slide, which moves into place once the slide aligned with the slide ejection slot has been ejected. Once all slides have been ejected from the case, the case is discarded.

Patent CA-2275521-A1 (CA)
Title: Bumps in grooves for elastic positioning
Inventor: BODOE JAN PETER
IPC: H01L21/60
Filed: 1997-12-19
Abstract: This invention belongs to a mounting technology for aligning parts, a selfaligned elastic positioning. A problem this invention solves is alignement of parts without using mechanical fine pre-alignment. Wherein one part has elastic bumps, another part has V-grooves and the parts fit into each other. The invention is using elastic material for the bumps to fit the V-grooves. Whereas the bumps are made of elastic material and shaped partly to the Vbumps by moulding. The two parts can slide along in the direction perpendicular to the plane of the surface of the part. The movement in the perpendicular direction can be controled by an external force. This means that the bumps and V-grooves have good alignment in xy-orientation and are also partially aligned in z-orientation. The elasticity of the bumps allows for thermal expansion differences without stresses to the parts while maintaining high precision alignment at a point. By using this type of parts they can be disassembled and be replaced without destroying the alignment features.
Patent CA-2276022-A1 (CA)
Title: Environmentally stable products derived from the remediation of contaminated sediments and soils
Inventor: KAO RICHARD L
IPC: C04B18/04
Filed: 1997-12-23
Abstract: This invention relates to thermo-chemical remediation and decontamination of sediments and soils contaminated with organic contaminants as well as inorganic materials with subsequent beneficial reuse.  Novel environmentally stable products of commercial value are produced when certain additives such as calcium and metal oxides are mixed with the contaminated materials. In the process, the mixture is heated to 1150 °C - 1500 °C to produce a molten reaction product with at least part of an excess amount of oxygen mixture or air is continuously bubbled through the melt in order to provide mixing and achieve high thermal destruction and removal efficiencies of the organic contaminants. The melt is then quickly quenched in moist air, steam, or water to avoid the transformation of the amorphous material into crystals. The inorganic contaminants such as chromium, nickel, zinc, etc. are incorporated and completely immobilized within the amorphous silicate network. Atmospheric emissions resulting from this process are nontoxic and capable of meeting currently specified health and environmental requirements. The amorphous material can be pulverized to yield a powder which evinces cementitious properties either by reaction with alkali solution or by blending it with other materials to produce blended cements. The compressive strengths of the concretes made from the powder of the subject invention and blends thereof are comparable to, or greater than the ASTM requirements for general purpose concrete applications. The powder of the subject invention, blended cements, and concrete/mortar derived therefrom also easily pass the EPA TCLP leach test to achieve environmental acceptability.
