Patent CA-2169343-A1 (CA)
Inventor: CURRIE JOSEPH E
IPC: F21V33/00
Filed: 1996-02-12
Abstract: An illumination device illuminates a tap handle and an area proximate to a tap outlet.   The device illuminates a stream of fluid flowing from the tap outlet and the receptacle into which the fluid flows when the tap handle opens the tap to release the fluid.  The tap handle actuates a tilt switch adjacent to the tap handle.   The device illuminates a tap handle when there is no fluid flow.  Light from lamps contained within the device is communicated to the tap outlet and tap handle by separate fiber optic lines.

The device includes a capacitor for generating a time delay to prevent false control signals from being relayed to the lamps.
Patent CA-2171188-A1 (CA)
Inventor: ZOOK JAMES DAVID
IPC: G01L1/18
Filed: 1993-09-07
Abstract: A resonant strain gauge includes a beam attached at both ends to a substrate. A cover cooperating with the substrate encloses the beam within a sealed vacuum chamber. A first bias electrode is formed on the cover and a second bias electrode is formed on the substrate directly beneath and spaced apart from the beam. The first and second electrodes are biased at constant voltage levels of equal magnitude and opposite polarity. A drive electrode is formed on the beam at one end of the beam. A piezoresistor is formed on the other end of the beam. A shield electrode is located between the drive electrode and the piezoresistor. The drive electrode, ordinarily biased at ground, is selectively charged by applying an oscillating drive voltage to cause mechanical oscillation of the beam. The piezoresistor detects the position of the beam. Beneficially, the piezoresistor detects the position of the beam with the use of a linear force applied to the drive electrode and with minimal impact from parasitic capacitance.

Title: Method and cartridge seal for packing a valve
Inventor: CORNETTE KEVIN RIELY
IPC: F16K41/14
Filed: 1996-06-10
Abstract: A packing system, for providing a seal around a valve stem, including a packing cartridge and a bushing.  The packing cartridge includes a sleeve which has a tapered central passage.   The sleeve also has external male threads and a hex head. Packing material is attached to the tapered central passage of the sleeve using an adhesive.
