Patent CA-2133047-A1 (CA)
Title: System for monitoring the insulation quality of step graded insulated high voltage apparatus
Inventor: MEYER THOMAS J
IPC: G01R31/12
Filed: 1994-09-27
Abstract: A non-ferrous current sensor is used to continuously measure the charging current magnitude in step-graded foil and paper insulation systems used on high voltage measurement and control apparatus such as instrument transformers and on the condenser bushings of power transformers and circuit breakers. The low voltage measured signal is conditioned by an electronic circuit such that it modulates a DC signal in a system current control loop to provide continuous remote monitoring and alarm functions. Remote power is supplied to the sensor and conversion circuits through the current loop. Alarm level thresholds and alarm time delay are embodied in a control device which may be located in a remote location, away from the high voltage equipment. Step-graded insulation systems form a capacitively divided circuit between the high potential and ground. As the dielectric between the foil layers breaks down, the total capacitance of the insulation system increases, producing an increase in the charging current. The sensor detects changes in the charging current through the insulation ground conductor, indicating the degradation of the dielectric properties between the foil layers. Continuous monitoring of the alarm relay contacts provide a means for reporting abnormal conditions and initiating event-based maintenance procedures. The modulation of a standard 4-20 mA current control loop allows for a multiplicity of monitoring equipment to be added to the system for additional data collection and reporting.

Title: Accurate placement and retention of an amalgam in an electrodeless fluorescent lamp
Inventor: BOROWIEC JOSEPH C
IPC: H01J7/22
Filed: 1994-10-03
Abstract: ACCURATE PLACEMENT AND RETENTION OF AN AMALGAM IN AN ELECTRODELESS           FLUORESCENT LAMP                      Abstract An amalgam is accurately placed and retained in an optimized location in the exhaust tube of an electrodeless SEF lamp for operation at a mercury vapor pressure in the optimum range from approximately four to seven millitorr by forming a dimple in the exhaust tube and using a dose locating member to locate and retain the amalgam on the side of the dimple away from the core of the lamp after filling the lamp.  As an alternative, two dimples may be situated on opposite sides of the exhaust tube for performing the same function as, but with less depth than, the single dimple.  In another alternative embodiment, first and second dimple configurations are formed in the exhaust tube after tip-off thereof, each dimple configuration including either one or two dimples.  The second dimple configuration is spaced apart from the first dimple configuration along the length of the exhaust tube.  In this way, the amalgam may be initially positioned farther from the tip-off region, thereby avoiding problems during tipping off of the exhaust tube, such as loss of mercury from the lamp, or quenching of the tip-which could cause stress cracks.  After tip-off, the second dimple configuration allows for placement of the amalgam closer to, or preferably in contact with, the tip of the sealed exhaust tube, i.e., the coolest location in the exhaust tube.

Title: Computer keyboard with electrostatic discharge feature
Inventor: ENGLISH GEORGE P
IPC: H01H13/02
Filed: 1993-05-05
Abstract: A computer keyboard according to a preferred construction has multiple non-conductive keys and at least one conductive key mounted in a keyboard housing. The conductive key includes a molded plastic key body having conductive material em-bedded therein. Conductive plugs are electrically coupled and mounted to the conductive key body. An electrostatic discharge pad is provided on a switch assembly positioned beneath the keys of the keyboard. The discharge pad is coupled to ground through a path resistor. When the conductive key body is depressed to an activated position, the plugs engage the electrostatic dis-charge pads so that electrostatic charges of the user progressively dissipate to ground through the key body, plug, discharge pad, and path resistor. At least one of the path resistor or the plug has a resistance greater than the resistance of the conductive key body. In this manner, electrostatic charge is routinely dissipated from a computer user while insuring that the user is not shocked when he/she initially touches and operates the conductive key.

Inventor: NISHIYAMA NAOKI
IPC: H04B10/2507
Filed: 1995-02-06
Abstract: An improved analogue photodiode module is provided herein. This improved analogue photodiode module includes an optical fibre having an end for transmitting light beams including a plurality of amplitude-modulated signals of different frequencies. A ball lens is provided for converging the light beams which are emitted from the optical fibre at different points on a central axial line, the beams which are closer to the central axis being converged at farther points from the ball lens, and the beams which are farther from the central axis being converged at closer points to the lens. The ball lens provides a maximum sensitivity range with a definite length for the position of an end of the optical fibre. The ball lens provides an aberration which makes a peak of signal distortion at a point which is farther than a middle point (Z0) of the maximum sensitivity range from the ball lens, the end of the optical fibre being positioned at a point (Z1) which is within the maximum sensitivity range which is closer to the lens than the middle point (Z0) and giving a second order distortion IMD2 which is lower than a predetermined value. A photodiode is provided for receiving light beams which are converged by the ball lens and for converting the light beams electric signals. A package is provided for holding the photodiode, and a cap is provided for sealing the package and for supporting the ball lens. A ferrule is provided for holding an end of the optical fibre and a holder is provided for fixing the ferrule to the package. Thus in the present invention, the end of the fibre is positioned at a point which is closer to the lens than the maximum sensitivity range and gives distortion which is smaller than the predetermined value.      High sensitivity and low distortion are compatible at that point.
