Title: Expert system for detecting high impedance faults
Inventor: RUSSELL B DON
IPC: G06F11/25
Filed: 1994-09-28
Abstract: An expert detection system (10) includes a method and apparatus for detecting high impedance faults occurring on a distribution circuit (12) coupled to an AC power source (14). Based upon an expert's knowledge of high impedance fault behavior and the performance of various fault detection techniques, the expert forms a belief (120) as to whether a high impedance fault has indeed occurred.  The expert's beliefs may be adjusted (130) with an elliptic formula, and then used to weight the status output of each technique. The weighted multiple technique outputs are combined to determine whether a high impedance fault has occurred. The expert's beliefs are calibrated during initial start-up (160) by comparison with a confirmed performance history of the detector using a scoring rule (170). The belief calibration may be included during operation to provide on-line adaption of the expert detector (10) to the changing situations of the distribution circuit (12).

Patent CA-2155786-A1 (CA)
Inventor: CHOBOTER GEORGE E
IPC: B26D7/10
Filed: 1995-08-10
Abstract: A method and apparatus is provided for heating vinyl composition tiles which are then amenable to cutting with a knife along complex contours without damaging the tiles. A stack of heating trays are located within a protective housing. The housing is supported on wheel means for ease of transport about the worksite and has one open side so that tiles can be loaded onto each of the trays. A discrete electrical heating element heats each tray and tile to a uniform temperature which renders the tile sufficiently elastic to be cut along any desired contour without fracturing. The trays are spaced appropriately so that tiles can be individually seized for cutting by the installer. The combination of the number of trays and the heating element's heat transfer capability enables an installer to repeatedly seize a sufficiently heated tile, re-load the vacant tray, and then seize another heated tile from the next sequential tray on a cyclical, sustainable basis. For added convenience, it is preferable that each tray be provided with a mechanical tile extractor and that the housing contain a cold tile storage compartment.
Patent CA-2156793-A1 (CA)
Title: Cartridge-loading apparatus and method
Inventor: DAVIS MARVIN B
IPC: G11B11/105
Filed: 1995-08-23
Abstract: The mechanism for loading and unloading a disk cartridge uses two sliders (one on each side of a base plate), which move in opposite directions under the influence of a tiller. Each slider has a slot to receive one of the two lifting pins provided on the cartridge receiver. The movement of the sliders drives the lifting pins along the slots, thereby raising or lowering the cartridge receiver depending upon the direction of rotation of the tiller. The sliding motion of the lifting pins engaged in the S-shaped slots thus unloads a disk from or, alternatively, loads the disk onto the drive spindle. As the lifting pins travel along their respective slots, the lifting and lowering of the disk is accomplished in such a manner that the disk hub is peeled from the spindle magnet rather than being lifted vertically off the spindle. This reduces the peak force required to break the magnetic clamp force between the spindle magnet and the disk hub. In this system, the dust door is attached to the cartridge receiver, and the label end of the loaded cartridge remains visible when the disk is loaded. This system may include a bias coil assembly rotatably mounted on an arm so that the bias coil assembly may be loaded into or extracted from the disk cartridge and placed out of the travel path of the disk cartridge. The rotation of the bias coil arm is effected by one of the sliders.

IPC: H02J1/00
Filed: 1994-03-02
Abstract: A loop-powered intelligent transmitter for process control variables is provided which can operate at an average current in excess of the minimum value of current that can flow in the loop. In order to keep the average current drawn down to the actual loop current, execution of a control program by a microprocessor incorporated in the transmitter is slowed down to the extent necessary to reduce current demand of the transmitter to that available. Slowing down is preferably accomplished by sensing when a current deficit occurs and placing the microprocessor in sleep mode to reduce current consumption until the deficit is made up. Entry into sleep mode may be deferred during time critical operations of the microprocessor.

Filed: 1995-10-27
Abstract: A gauge wheel assembly includes a gauge wheel arm that straddles the rig tube and is supported on the tube by two bushings inserted through holes on either side of the tube. The bushings contact each other near the center of the tube to provide a solid or hard joint which permits the pivot bolt to be tightened without crushing the sides of the tube.  The bushing has protrusions that are pressed into the tubing wall during installation and thereby prevent bushing rotation.  Two different straps at the lower end of the wheel arm permits at least three different combinations of gauge wheels to be quickly and easily mounted.  A compact and easily accessible depth adjusting crank is supported entirely above the rig tube.  A depth indicator projects from the crank trunnion mounting on the upper end of the wheel arm to provide an indication of depth adjustment.

Patent CA-2167424-A1 (CA)
Title: Emission seal
Inventor: ORLOWSKI DAVID C
IPC: F16J15/34
Filed: 1996-01-17
Abstract: The shaft seal assembly of cartridge designed for sealing shafts entering or exiting enclosed vessels. The enclosed vessels may have a pressure different from the atmospheric pressure and the seal will normally prevent leakage from or into the vessel. The seal is accomplished by having a plurality of fluid pressures presented to different faces or portions of the seals. Utilization of these pressures provides a seal between the faces of the rotating parts and the stationary parts of the seal with a minimum of friction.      This reduced friction is a result of some amount of air movement between the sealing faces. This air movement into and out of the seal, resulting from fluid pressure different-ials, will also carry away any contaminants that may get into the seal, either to the ambient atmosphere or to a recovery system. The seal is designed to accept axial and radial shaft displacement while maintaining a positive seal between the vessel and the atmosphere. The seal of this invention inclu-des force loading of the rotating members toward the station-ary members, each member with its own sealing face. The force of the loading means is modified by utilization of a first pressure to decrease the loading force and a second fluid pressure proportionate to the first fluid pressure applied to increase the loading force. The first and second fluid press-ures provide a barrier to the flow of materials in either dir-ection through the seal. The rotating members are driven by drive rings which also act as sealing members along the shaft.
