Patent CA-2342467-A1 (CA)
Title: Multi-frequency tone detector
Inventor: SCHULZ DIETER
IPC: H04Q1/46
Filed: 2001-03-13
Abstract: A multi-frequency tone detector with analysis window (i.e. filter size) chosen such that spectral nulls are located at adjacent frequencies of interest. The decision logic block of the tone detector uses the roll-off characteristics of the filter in conjunction with background noise to determine a threshold pass/fail for any tone that has deviated excessively from its nominal value. The foregoing aspects of the invention result in simple filter design (i.e. reduced order) relative to prior art tone detectors.

Abstract: A method of manufacturing a hollow core door is disclosed, as well as a corresponding hollow core door. The method includes the steps of providing a solid flat door skin, moisturizing the flat skin, applying a conditioning resin thereto, preheating the flat door skin, and thereafter pressing the flat door skin between a pair of heated platens in a press in order to reform the flat skin into a molded skin including a plurality of panels defined therein. The press continuously closes in order to reform the flat skin into the molded skin, with the rate of press closure being a function of the determined hardness of the flat skin to be reformed. The resulting door skins have an improved bond strength, and are efficiently manufactured.

Title: Anti-inertia stacker
Inventor: WARD LAWRENCE A
IPC: B65G57/09
Filed: 2001-04-27
Abstract: An anti-inertia stacker for products which are prone to dislodgment on or from a substrate during processing movement is provided. The anti-inertia stacker comprises a traveling pallet which is mounted for movement. The traveling pallet receives a product-laden substrate from a conveyor or other placement device while traveling at substantially the same speed as the conveyor. The traveling pallet includes a conveying surface which moves in a direction opposite to a direction of travel of the traveling pallet. The conveying surface, moving in the direction opposite to the direction of travel of the product-laden substrate, decelerates the received product-laden substrate. The product-laden substrate can then be stacked without dislodging the product from the substrate.

Title: Atmospheric-pressure plasma decontamination/sterilization chamber
Inventor: HERRMANN HANS W
IPC: A61L2/14
Filed: 2000-06-08
Abstract: An atmospheric-pressure plasma decontamination/sterilization chamber (10) is used for decontaminating sensitive equipment and materials, such as electronics, optics and national treasures which have been contaminated with chemical and/or biological warfare agents, such as anthrax, mustard blistering agent, VX nerve gas, and the like. The apparatus may also be used for sterilization in the medical and food industries. Items (28) to be decontaminated or sterilized are supported inside the chamber. Reactive gases containing atomic and metastable oxygen species are generated by an atmospheric-pressure plasma discharge in a He/O2 mixture and directed into the region of these items (28), resulting in chemical reaction between the reactive species and organic substances. This reaction typically kills and/or neutralizes the contamination without damaging most equipment and materials.  The plasma gases are recirculated through a closed-loop system to minimize the loss of helium and the possibility of escape of aerosolized harmful substances.
