Patent CA-2195032-C (CA)
Title: Methods and apparatus for operating a discharge lamp
Inventor: MOSKOWITZ WARREN P
IPC: H05B41/292
Filed: 1997-01-14
Granted: 2005-01-04
Abstract: Methods of operating a discharge lamp by amplitude-modulating and pulsing the lamp input power waveform. The techniques control both the arc stabilization and color characteristics of the lamp, respectively. The alternating current (AC) input waveform is amplitude-modulated to stabilize the arc with a swept AC periodic wave (such as a sine wave, sawtooth wave, square wave, etc., or a combination thereof). The swept wave can be generally swept from about 20 kHz to 60 kHz, with a preferable band sweep of from approximately 40 kHz to 50 kHz. The sweep can also be patterned (such as allowing the sweep to have stepped rises and falls within the sweep cycle). The sweep may also contain multiple-frequency sweeps that are bundled together to modulate the carrier wave. These modulation forms are used to center, constrict and stabilize the arc. In addition to this stabilization, the lamp input waveform is pulsed to control and regulate the color characteristics of the lamp.

Patent CA-2221176-C (CA)
Inventor: NICHOLSON JAMES E
IPC: G01J3/12
Filed: 1996-05-09
Granted: 2003-11-04
Abstract: An incident optical signal is captured by an array of apertures and directed to pairs of fibers, each pair having a delay fiber with a unique length and a no-delay fiber. Each pair of fibers further has a unique transmission characteristic. Time interpolation is then performed using the transmission characteristic curve for each delay fiber and the duration from the time the optical signal arrives over the no-delay fibers and the time the signal arrives over the delay fibers to determine the wavelength. In a second embodiment, each pair of delay and no-delay fibers is replaced by a fiber splitter which directs light into a no-delay fiber and a delay fiber that have been split from the input of the splitter. In a third embodiment, two fiber splitters are used in place of the pairs of fibers. Each splitter has a number of branches for receiving light and an output end for guiding light onto the photodetectors. The propagation time of the delay optical signal, as compared against the no-delay signal, and other factors such as the length of the individual fiber and the transmission characteristics, are used to determine the wavelength.

Title: Method and device for producing and utilizing gas from waste materials
Inventor: BUSCH MICHAEL
IPC: F23G5/46
Filed: 1997-11-28
Granted: 2001-10-09
Abstract: In this process for gasifying and burning waste materials, the waste materials are introduced into an incinerator (1) and end up on a burning grate (6) to which air is conducted by means of various undergrate forced draft chambers (8a to 8e). In the first area air is introduced at a superstoichiometric level in order to ignite the waste materials. Then, via the undergrate forced draft chambers (8c to 8e), oxygen is mixed into the air which is used for the gasification, at the same time establishing a substoichiometric level which leads to gasification of the waste materials. These combustible gases which come about in the process pass via the waste gas flue (12) into a second furnace (2), in which the gases are burned at a superstoichiometric level through the introduction of combustion air. The resulting waste gases pass to a heat exchanger (3).             (Figure)

Abstract: L'invention porte sur un procédé perfectionné sans alcool, de fractionnement de gluten en gliadine et gluténine, dans lequel une dispersion acide de gluten est formée avec un réducteur (par exemple du métabisulfite de sodium) pouvant casser les liaisons disulfures dans la protéine de gluten. Le pH de la dispersion est ensuite augmenté pour que la gluténine précipite, laissant la gliadine en suspension dans la dispersion. La gluténine et la gliadine peuvent alors être séparées par décantation ou centrifugation. Dans le mode de réalisation préféré, la dispersion est réacidifée avant la séparation afin de parvenir à un meilleur degré de séparation de gluténine et de gliadine.
