Patent CA-2108443-A1 (CA)
Inventor: ROBERTS JEFFREY B
IPC: H02H3/08
Filed: 1993-10-14
Abstract: A directional element measures the negative. sequence voltage and the negative sequence current and from those quantities produces a scalar quantity related to the negative sequence impedance of a power transmission line relative to the location of the directional element. The scalar quantity is then compared against two threshold quantity settings, one to determine a forward fault, the other to determine a reverse fault. The scalar quantity must be less than the forward threshold quantity for a forward fault and greater than the reverse threshold quantity for a reverse fault.

Title: Software for executing plural independent application programs
Inventor: RICKENBACH BRENT L
IPC: G09G5/14
Filed: 1991-09-25
Abstract: A plurality of computer application programs (66a, 66b, ...66n) have respective display generation routines (64a, 64b, ...64n) for generating respective program video displays onto a computer display screen (58). Backplane software (50) operates all of the respective display generation routines (64a, 64b, ...64n) to generate overlayed, composite video display of the respective program video displays. The software system (50) fuses the display outputs of each of a plurality of independent application programs (66a, 66b, ...66n) into a single overlayed screen display. More particularly, the software backplane architecture (50) interrupts the draw subroutine calling sequences of each independent application program, and redirects those sequences to the backplane software (50). The backplane software (50) initiates a redraw command to the application program to in turn operate the display generation routines to cause a display. Since all of the independent application programs (66a, 66b, ...66n) have draw sequences under control of the backplane software (50), the application programs remain independent of each other.

Title: Pulsed laser discharge stabilization
Inventor: COHN DAVID B
IPC: H01S3/036
Filed: 1994-10-11
Abstract: PULSED LASER DISCHARGE STABILIZATION                     ABSTRACT OF THE DISCLOSURE Low power discharge preionizers, or species (34), are provided by a ionizable species generator (20) that preconditions a laser gas (18) to eliminate arcing in lasers (10), such as pulsed (high repetition rate) lasers (10). The present invention creates the species (34) in a low power discharge and the species (34) prevents initial arcs from occurring between high voltage electrodes (14, 14a) of the laser (10). The laser (10) comprises a pressure vessel (11) containing the laser gas (18), a fan (12) for circulating the laser gas (18), a heat exchanger (13), a catalyst (17a), and two high voltage discharge electrodes (14, 14a) for exciting the laser gas (18) to create lasing. A high voltage power source (21) is coupled to the electrodes (14, 14a) for providing adischarge voltage thereto. A primary auxiliary discharge source (19) is disposedadjacent to the electrodes (14, 14a) that is used as a preionizer that create a low density of charged particles in the main discharge volume to act as a uniform seed for the main voltage pulse derived from the electrodes (14, 14a). The ionizable species generator (20) is disposed in the pressure vessel (11) and provides a low power discharge that preconditions the gas (18) to eliminate arcing in the laser (10). A preionization discharge generated by the ionizable species generator (20) is used to generate species (34) that have low ionization potential. These easily ionized species are then preionized by ultraviolet radiation generated from the primary auxiliary discharge adjacent to the main discharge electrodes (14, 14a) to form a uniformly ionized background for the main discharge to work on. The low ionization potential species (34) replace the gas hydrocarbon contaminants that are adsorbed by the catalyst (17a). A method of eliminating arcing in the laser (10) is also disclosed.

Patent CA-2126384-A1 (CA)
Title: Circular saw guide
Inventor: WENNINGER OTTO
IPC: B27B9/04
Filed: 1994-08-12
Abstract: In a tool for guiding a circular saw it is known for the outside edge of the base of a circular saw to slide along a straight piece of material (usually aluminum) which is clamped into place. In this invention the saw actually rides on the guide and that guide is kept in place by a rubberized coating on the bottom side.          Specification: 1-  This invention relates to guiding a circular saw for cutting various materials (concrete, metal, plastic etc.)but mostly lumber and lumber related products (2x4's, 2x6's etc., plywood, ranger board, particle board etc.). 2-  In devices for guiding circular saws it is common for the outside edge of the base of the circular saw to slide along a straight edge. Guides  of this type, however, are inefficient because you have to spend time making two measurements; the actual line where the sawblade makes the cut and the line where the straight edge of the guide is lined up on (basically the difference between the saw blade and the outside edge of the base of the circular saw) and you have to clamp it to the object you want to cut, which is not always possible.  One other drawback is the difficulty in cutting uneven surfaces because the base of the circular saw rides on the material you are actually cutting. 3-  I have found that these disadvantages can be overcome by rubberizing the underside of the guide (similar to a router blanket).  This keeps it in place so no clamping is necessary, which in turn, saves you time; it also gives you more possibilities in confined spaces or where clamping is not possible but you still need accurate cuts.  With this guide you only have to make one measurement because the part of the base up to the sawblade of the circular saw actually rides on the guide, you only have to line it up visually to whatever cutting mark you make.  Because the saw rides on the guide, uneven or rough surfaces aren't as big of a problem.  This guide is a fast and efficient way for the experienced or inexperienced woodworker to make straight, accurate, and professional cuts.
Patent CA-2128673-A1 (CA)
Inventor: BARGHOUTI NASER S
IPC: G06F9/44
Filed: 1994-07-22
Abstract: Techniques for controlling a process which is performed at least in part by a device such as a computer operating system. The techniques involve a process server which controls the process in response to indications that steps of the process have taken place, an envelope which encloses the device and generates event messages when the device performs operations, and a translator which translates steps of the process into sequences of events and monitors the event messages. When the translator determines that a sequence of events which constitute a process step has occurred, it provides an indication that the step has occurred to the process server. In a preferred embodiment, the device is an operating system, the envelope is a dynamically-linked library of file system commands, the translator includes the Yeast event-action system, and the process server is a process control system which models entitiesinvolved in the process as objects and makes state transitions by firing rules which modify the objects.
