Title: Method of controlling welding current and inverter-controlled dc resistance welding apparatus
Inventor: TAKANO FUMITOMO
IPC: B23K11/24
Filed: 1998-01-21
Abstract: Before a deterioration of a secondary current sensor is detected, a controller effects a feedback control process based on a secondary current from the secondary winding of a welding transformer which is energized by an inverter, for thereby controlling a welding current with a high degree of accuracy, e.g., an accuracy level of ~ 1 %.  At the same time, it is monitored whether a detected value of a primary current from the primary winding of the welding transformer, which is detected by a primary current sensor, exceeds a predetermined allowable range with respect to a reference value of the primary current.  If the detected value of the primary current exceeds the predetermined allowable range, then it is decided that the secondary current sensor is deteriorated.  When the secondary current sensor is deteriorated, the controller switches from the feedback  control process based on the secondary current to a feedback control process based on the primary current to control the welding current with a certain degree of accuracy, e.g., an accuracy level of ~ 3 %, without interrupting the welding process.

Abstract: A method and apparatus for removing solids from a substantially horizontal section of a wellbore which allows the use of coiled tubing as a workstring without requiring the  removal  of  the  production  tubing  from  the  wellbore. Guide tubing, which  is  left  in the  wellbore,  extends  from the  surface through the horizontal  section and  is  adapted to guide a string of slightly smaller-diameter,  coiled tubing through the  horizontal  section.    Wash  fluid,  e.g.  water,  flows through a nozzle on the coiled tubing and out through openings in the guide tubing directly into the solids to form a slurry therewith.   The slurry is then pumped out of the wellbore through the production tubing and/or reenters the guide tubing through other opening(s) therein to flow to the surface through the annulus which exists between the coiled tubing and the guide tubing.
Patent CA-2228897-A1 (CA)
Inventor: SMITH DANIEL ROBERT
IPC: H01H51/22
Filed: 1996-07-30
Abstract: A polarized electromagnetic relay includes a base, an electromagnet with a coil and a pair of pole pieces extending perpendicularly from the end of said coil, a balanced armature and spring system which when actuated pivots between two fixed contact points and a permanent magnet inducing the same magnetic poles in both of said pole pieces and providing an opposite pole in closely adjacent relationship to the central portion of the armature. A movable contact spring is fixedly connected to the armature, said spring forming contact arms at either armature end portion. Further, a flexible movable braid connects the movable contacts on said movable spring to each other and to a movable contact terminal. A pair of retaining tabs extending from a central bobbin flange engaging corresponding recesses at the lateral sides of the armature limits the movement of the armature in two directions as well as its rotation. This feature eliminates the need for a torsion spring and allows the contact forces to be higher if necessary. Two identical coils wound in a common direction are provided as the means for actuation. Armature transfer will occur by either applying a voltage pulse across the appropriate coil, or by toggling the voltage pulse polarity across the two coils connected in series.

Patent CA-2229936-A1 (CA)
Title: Kitchen exhaust system with catalytic converter
Inventor: BAGWELL RICK A
IPC: B01D53/88
Filed: 1997-06-18
Abstract: A kitchen exhaust system for a smoky cooking appliance includes a modular exhaust hood (11) with a catalytic converter (22). High catalyst temperatures are obtained with a minimum of auxiliary heat. The exhaust hood (11) is tapered for forming a converging channel leading to an inlet slot (19), located over the middle of the cooking area, through which the exhaust flow passes to the catalytic converter (22). The slot (19) is sized to match the flow through the inlet and an average natural-convection plume velocity from the cooking appliance. A portion of the treated effluent stream (27) is recirculated to form a capture jet (24) at the front of the hood (11) to create a local negative pressure that reduces potential for entrainment of fumes into the surrounding area without increasing exhaust volume. A control system provides for self-cleaning of the catalyst. Auxiliary burners (28) are employed to insure catalyst inlet temperatures are sufficient for ignition of the catalyst. Heat is added to promote the incineration and/or vaporization of aerosol particles. To do this, hot exhaust from the burner (28) is injected directly into the effluent stream (17). Acceleration of the main flow is promoted during a turbulent mixing regime, characterized by a fluctuating temperature field, upstream of a phase in which molecular diffusion dominates. The acceleration causes the particles to migrate, relative to the carrying flow, through the varying temperature field, causing incineration/vaporization with less heating of the cool carrying gas.

Title: Tdm array of optical non-acoustic pressure sensors
Inventor: FREDERICK DONALD A
IPC: G08C15/00
Filed: 1998-07-07
Abstract: A pressure measuring device which utilizes an array of optical, non-acoustic pressure sensors with a laser light source which generates a pulsedlight signal into a light transmitting cable, wherein the pulsed light signal propagates along the light transmitting cable through the array of optical pressure sensors. A plurality of optical couplers are attached to the light transmitting cable at multiple locations spaced apart from one another in order to branch off at least a portion of the pulsed light each location. Each of the plurality of optical couplers includes a respective optical pressure sensor and a pressure insensitive reflector, wherein the branched off portion of the pulsed light signal is transmitted into to both the optical pressure sensor and the reflector. Each optical pressure sensor reflects a pressure indicating signal back into the optical coupler, while the pressure insensitive reflector reflects a reference signal back into the optical coupler. The pressure indicating signal and the reference signal are reflected through the optical coupler into the light transmitting cable as a pair of non-overlapping pulsed signals, which are then retrieved from the light transmitting cable by a signal detector. The retrieved pressure indicating signal is compared with the retrieved reference signal to determine the pressure acting upon the optical pressure sensor.

Title: Fade detector for digital video
Inventor: WU SIU-WAI
IPC: H04N7/26
Filed: 1998-07-30
Abstract: Static fade in a digital video image is detected. A difference in luminance intensity, is determined for correspondingly positioned pixels in successive images. A variance in the difference is determined, and then normalized according to a mean squared value of the difference to provide a fade index J n. The fade index is compared to a fade threshold, e.g., 0.9, to determine if a fade is indicated. Optionally, a check may be made to verify that a static fade is indicated by comparing the mean squared value of the difference to a motion threshold. The technique is suitable for both frame mode and field mode video sequences. When the digital images include field mode video, where each image has first and second fields, a fade index is determined separately for each field, and an overall fade index is obtained by averaging the fade indexes from each field. A scheme for detecting static fade on a macroblock by macroblock basis is also presented.

Title: Surface treatment of circular saw blades
Inventor: ACHTERBERG NICHOLAS E
IPC: B23D63/18
Filed: 1998-07-31
Abstract: A carbide-tipped circular saw blade is formed by brazing cutting tips of tungsten carbide to the teeth of a steel blade blank, thereby creating discoloration on the planar surfaces of the blade adjacent the rim. Substantially the entire surface of the blade is sandblasted with blast media to remove the discoloration while generating a substantially uniform coloration and texture to the planar surfaces of the blade. User-readable graphics are overprinted upon the blasted surface. The graphics and the surface appearance of the blasted area are selected to be at a predetermined contrast, and the carbide cutting tips retain a visual appearance different from the rest of the blade, such that the graphics and cutting tips are visually perceptible to a potential purchaser at the blade's point of sale. The saw blade surfaces are sandblasted by jets directed at both sides of the saw blade. The blast nozzles are oriented such that the vertical components of force of the jets offset one another. This assists in minimizing the blade warping that would otherwise occur due to the sandblasting operation. In all-sandblasted "softbody" blades, a reduction of 20% in deviation from flatness has been achieved compared to similar blades which are polished and rim-blasted.
