Title: Efficient utilization of chlorine and moisture-containing fuels
Inventor: DICKINSON NORMAN L
IPC: F01K3/18
Filed: 1994-11-14
Abstract: Disclosed is a method and system for recovering energy from low-grade fuels such as industrial, municipal and agricultural waste, low-grade carbonaceous fuels such as lignite and similar solid fuels in which the fuel is comminuted into small particles and slurried in water. The alkali content of the slurry is adjusted to be at least about equal to the chemical equivalent of the halogen content of the slurry and, following pressurization of the slurry, it is heated sufficiently so that the substantial portion of chemically bound oxygen in the fuel separates therefrom as carbon dioxide, leaving a slurry including char particles and dissolved impurities such as halogen salts. The char particles are removed from the slurry and reslurried with just enough halogen-free water to provide the slurry with the needed viscosity to maximize the energy density thereof. The char particles are then reacted with air at a temperature below their ignition value to convert the fuel value of the low-grade fuel into thermal energy which is then further used, for example, to drive a turbine (253, 255, 257).

Title: Spacer-frame bar having integral thermal break
Inventor: PETERSON WALLACE H
IPC: E06B3/663
Filed: 1996-05-17
Abstract: An elongate tubular spacer-frame bar (18) having an integral thermal break for reducing energy flow between glass panes (14) in an insulated glass panel (10) is provided. The spacer-frame bar (18) includes a first and a second side (24, 25), each side having elongated edges (28, 29). Two nonwelded seams (26) run along the elongate dimension of the spacer-frame bar between the corresponding adjacent edges of the first and second sides. At least one continuous insulating member (30), composed of a nonmetallic, low-heat-conductive substance, and being of a length substantially equal to the length of the spacer-frame bar, separates the first and second sides of each seam, forming a thermal break. The present invention effectively eliminates all direct contact between the spacer-frame bars and the glass panes by separating the two halves of the spacer-frame bar along its nonwelded seams with a nonmetallic/nonconductive substance. This separation creates an effective thermal break along the spacer-frame bar that stops conductivity between the glass panes via the spacer-frame bar, thus further reducing the heat loss in insulated glass panels.
Patent CA-2178563-A1 (CA)
Inventor: RINAS DAVID EDWARD
IPC: H02G1/06
Filed: 1996-06-07
Abstract: A method of laying cable such as fiber optic cable which cannot be twisted past an obstacle includes rewinding the cable from the inner end through an excavation under the obstacle from a first reel onto a second reel downstream of the obstacle. Both the first and second reels are of a type having first and second end flanges both of which are removable from the reel and a radially collapsible hub. During the rewinding step, the supply reel from the plough is positioned on end and the cable withdrawn from the inner turns of the winding and pulled off over end thus introducing a turn of twist. The key to the system is that when the second reel is unwound at the obstacle it is inverted relative to the first reel so that the second end is uppermost thus causing the twist to be subtracted and cancelled rather than summated.

Abstract: The invention relates to a method of determining prefocused pulses with sufficiently low power and short duration to allow multi-slice in-vivo spectroscopic imaging of humans. The method has two main stages, analytic and numerical. In the analytic stage a magnetization response is selected with certain desired characteristics such as prefocused time. During the numerical stage, the response is then transformed into an RF pulse for use in magnetic resonance imaging. The theoretical response to the RF pulse is evaluated and characteristics such as duration and amplitude may be altered to meet further requirements. The theoretical response is then transformed into an RF pulse for use in magnetic resonance imaging or for further application of the numerical stage.

Title: Radiant space heater for residential use
Inventor: AHMADY FARSHID
IPC: F24D5/08
Filed: 1997-02-19
Abstract: A compact gas-fired radiant space heater is adapted for residential use, having an output in the 20k BTU to 40k BTU/hr range and exterior dimensions small enough to allow it to be installed in a standard two foot by four foot suspended ceiling opening. A radiator tube having a total length of approximately 15 feet is bent into a serpentine shape, and combustion control components are housed within a plenum chamber supplying combustion air to the tube, both the tube and the chamber being encircled by a frame that fits within the two foot by four foot opening.      The combustion control components are attached to a chassis plate whereby the components are removable from the plenum chamber as a unit to enhance serviceability of the heater.      A burner venturi of novel configuration produces a flame that is less than four feet long yet which is relatively quiet. An air flow switch senses the dynamic pressure of an air stream issuing from a fan which pressurizes the plenum chamber, shutting off the supply of gas to the burner if the pressure reading indicates unacceptably low air flow.

Title: Compilation of weighted finite-state transducers from decision trees
Inventor: SPROAT RICHARD WILLIAM
IPC: G10L15/28
Filed: 1997-03-27
Abstract: A method for automatically converting a decision tree into one or more weighted finite-state transducers.  Specifically, the method in accordance with an illustrative embodiment of the present invention processes one or more terminal (i.e., leaf) nodes of a given decision tree to generate one or more corresponding weighted rewrite rules.  Then, these weighted rewrite rules are processed to generate weighted finite-state transducers corresponding to the one or more terminal nodes of the decision tree.  In this manner, decision trees may be advantageously compiled into weighted finite-state transducers, and these transducers may then be used directly in various speech and natural language processing systems.  The weighted rewrite rules employed herein comprise an extension of conventional rewrite rules, familiar to those skilled in the art.
