Abstract: This invention discloses a method and an apparatus for gasification and vitrification of ashes, such as produced in a hog-fuel fired boiler, by means of a plasma arc. The ashes are introduced into a shaft furnace where two or three tiltable electrodes are located. The plasma arc is ignited between these electrodes which are then tilted from a horizontal to an essentially vertical position whereby the arc is lengthened and then broken into separate arcs, one between each electrode and the slag accumulated at the bottom of the furnace. This plasma arc helps to burn off the organics in the ashes, producing combustion gases that can be used as a source of energy for the boiler, and to keep the slag in molten state, which allows its periodic removal through a tap hole.
Patent CA-2190863-C (CA)

Granted: 2004-11-02
Abstract: A process is disclosed for fasten-ing windings in a permanent and reli-able manner without reducing the cool-ing cross-sections. Doses of an electro-conductive elastomer are introduced for that purpose approximately in the middle of the partial bundle of laminations, on the top of the bar and/or on the interme-diate piece. The elastomer material (9) is pushed upwards when the bottom bars (3) are pressed in or flows towards the middle of the conductive bar when the intermediate pieces (7) are laid in. No elastomer flows into the core ducts (10) of the partial bundles of laminations (11), so that the cooling cross-section is not narrowed. It thus becomes possible for the first time to glue the winding to the bundle of laminations in an elastic and stress-free manner. The main advantage however is that the dosed introduction of elastomer does not reduce the core ducts nor their cross-section.

Patent CA-2224340-C (CA)
Inventor: GREENE MICHAEL ROY
IPC: G01R31/36
Filed: 1997-12-10
Granted: 2000-04-11
Abstract: When a user has a portable telephone near the absolute end of its available battery power, the user can be caused to behave in a manner that more likely results in the preservation of some battery power for subsequent high priority high priority calls by conveying the illusion that the battery will soon be, or is, depleted even though there actually remains sufficient power in the battery to power the portable telephone for an additional period of time. To this end, at a predetermined time, e.g., two minutes, prior to a projected time at which the battery is expected to have power for only a particular additional amount of time, e.g., eight minutes, the user is signaled with an almost-out-of-power warning. This warning indicates that there remains in the battery enough power to operate the portable telephone only until the projected time, notwithstanding that there actually remains in the battery sufficient power to operate the portable telephone for the additional time beyond the projected time. To enhance the illusion of early battery power depletion, the portable telephone powers off at the projected time. Furthermore, any battery power indicator provides the user with an artificially low power reading that indicates that the battery power will be completely depleted at the projected time. At any point after initiation of the almost-out-of-power warning, the user may take an affirmative action to make available the additional power remaining in the battery. At that point, the display is restored to an accurate indication.

Title: Catheter tip mold and cut process
Inventor: BIALECKI DENNIS
IPC: A61M25/00
Filed: 1997-12-30
Granted: 2007-04-03
Abstract: The disclosed invention comprises a two step process for forming the tip of a catheter. In the first process a tapered catheter tip is molded by placing a tubular catheter over a mandrel and inserting the mandrel and catheter assembly into a mold having an inner mold surface. The molded catheter with flash is thereafter removed from the mold and the mandrel removed from the catheter. The catheter and flash are inserted into a jig which defines an opening through which the flash extends.       The opening is defined by a cutting surface and the flash extends above such cutting surface. A cutter is then moved along the cutting surface in order to severe the flash at precisely the appropriate point along the catheter length to leave a formed trimmed catheter. The catheter is thereafter removed from the jig for further processing.
