Patent CA-2190954-A1 (CA)
Title: Electrostatic fibrous filter
Inventor: COPPOM REX
IPC: B03C3/155
Filed: 1995-06-08
Abstract: The particle collection efficiency of a fibrous filter (11) is signifi-cantly increased by imposing a high voltage potential on electrodes (15, 16) placed on either side of the filter (17). This creates a strong elec-trostatic field across the filter (17) which enhances the fiber's particle collection ability. The electrostatic field strength, and particle collection efficiency, increase with the voltage employed to establish the electrostatic field. An insulated electrode (15) as the front electrode (15) in combina-tion with a conductive electrode (16) as the rear electrode (16) enables a very high electrical potential to be imposed on the electrodes (15, 16) without resulting arcing between the electrodes (15, 16). Pre-charging of dust particulates with the same polarity as the insulated electrode fur-ther increases collection efficiency without resulting in a charge buildup in front of the electrodes (15, 16) or a blocking of airflow by particles collecting on the electrodes (15, 16).

Patent CA-2201091-A1 (CA)
Inventor: SHERMAN DANIEL A
IPC: G02B6/06
Filed: 1997-03-26
Abstract: This invention relates to the ability of the user to view a distant object at a close range. for example, when used in the inspection of the human foot, it provides the user with the ability to transmit an enhanced image of areas of the foot, not normally visible to the naked eye, directly to eye level. This method of inspection, and the associated device, allows a patient suffering from a disease such as diabetes, to carefully inspect the bottom of his/her own feet without the assistance of another person. Further, the device described contains a source of illumination that will give the user the opportunity of viewing anomalies that may be hidden in the rough texture of the skin, or in dark areas that have been shaded by protrusions such as toes. Unlike reflected images that appear in mirrors, the device allows the user the ability to inspect their extremities with full range of motion, while segmenting a broad surface into definable fields of view. The device provides evenly lit, enhanced image transfer, without significant parallax distortion. The use of the device is not limited to the inspection of body parts. It may also provide the user with the opportunity to view objects hidden from obvious view, as in the case of automobile or airplane engines, which may contain damage hidden from front view as part of the opposing side of fixed parts that block direct inspection, and that cannot be viewed directly by the human eye, or directly illuminated with a flashlight or other conventional light sources.     In the case of plumbing fixtures located underneath a sink, the plumber must now crawl underneath the fixture to examine for leaks, while the device described in the instant art would allow him to simply place the instrument in the area to be examined, and do the entire inspection from a standing position with minimum effort.

Abstract: This invention relates to plant thioesterases, specifically plant acyl-ACP thioesterases having significant activity on stearoyl-ACP. DNA constructs useful for the expression of a plant stearoyl-ACP thioesterase in a plant seed cell are described. Such constructs will contain a DNA sequence encoding the plant stearoyl-ACP thioesterase of interest under the control of regulatory elements capable of preferentially directing the expression of the plant stearoyl-ACP thioesterase in seed tissue, as compared with other plant tissues, when such a construct is expressed in a transgenic plant. This invention also relates to methods of using a DNA sequence encoding a plant stearoyl-ACP thioesterase for the modification of the stearate produced in a plant seed cell. A plant thioesterase having significant activity on stearoylACP exemplified herein is from mangosteen. Modified stearate concentration may be obtained by expression of mangosteen thioesterase alone or in combination with antisense constructs for reduction of native stearoyl-ACP desaturase in plant seeds.

Title: Rerouting and change-back systems for asynchronous transfer mode network
Inventor: NAKAGAKI TATSURU
IPC: H04L12/56
Filed: 1991-06-17
Abstract: A change-back system is designed for an asynchronous transfer mode network in which a rerouting path is set to replace an original path when a fault is generated in the original path within the network, which network includes a plurality of communication nodes which are coupled via lines and communicate information in the form of cells, and the original path and the rerouting path couple first and second communication nodes within the network.  The change-back system makes a change-back process to change the path used from the rerouting path to the original path when the fault is restored.  The change-back system includes a first circuit for detecting a restoration of a fault in the original path, a second circuit for transmitting a cell from the first communication node to the second communication node via each of the rerouting path and the original path when the restoration of the fault is detected, prior to making the change-back process, and for measuring a first time it takes for the cell to travel through the rerouting path and a second time it takes for the cell to travel through the original path, and a third circuit for calculating a guard time which is a difference between the first and second times and for delaying transmission of a cell from the second circuit to the original path after the restoration of the fault, so that the cell after the restoration of the fault is transmitted to the original path at least after a time which corresponds to the difference from a time when a cell is last transmitted to the rerouting path immediately before the fault is restored.
