Patent CA-2399499-A1 (CA)
Inventor: SEAMAN DARRYL
IPC: G01N3/30
Filed: 2002-09-13
Abstract: This invention provides a mufti-purpose apparatus for delivering a well-defined quantity of mechanical energy to a specimen. In the collision embodiment, the apparatus is a two-car compression specimen tester. Cars are propelled by gravity on the same set of oppositely inclined rails that merge into horizontal segments where collision occurs.  This allows the kinetic energy of the cars to be dissipated into a compression specimen carried by one of the cars. Car release height affects the initial velocity of a car at impact. Car release height and car mass affect impact energy. In the sweep embodiment, the cars ride on separate tracks. One car grips a fracture specimen while the other carries a tup. The kinetic energy of the cars is partly dissipated into the fracture specimen. The specimen fracture energy is determined by measuring the initial and final height of the center of mass of each car.

Title: Optical structure for the compensation of chromatic dispersion and dispersion slope in a light signal
Inventor: MORIN MICHEL
IPC: G02B6/34
Filed: 2003-01-24
Abstract: A dispersion compensator for the compensation of chromatic dispersion in a multi-channel light signal is provided. The compensator includes a pair of optical structures each having a waveguide and a Bragg crating provided therein. The Bragg grating has a plurality of grating components, each associated with one or a few of the channels to be compensated. An optical assembly propagates the light signal sequentially through both optical structures. The periods of the grating components are selected to allow compensation of chromatic dispersion experienced by this particular channel or these particular channels, thereby taking into account the dispersion slope of the light signal. Tuning means are also provided in order to adjust the dispersion of the grating components of each optical structures, and proper selection of the tuning parameters allows tuning independently both the dispersion and dispersion slope.

Title: Pdf valve
Inventor: SZARKA DAVID D
IPC: E21B34/00
Filed: 2003-01-28
Abstract: A differential float and cementing valve assembly used to position and cement casing in a wellbore. A poppet valve mounted in the flapper gate of a check valve provides a regulated back-flow of drilling fluid through the check valve.        A leaf spring biases the poppet valve to its closed position.  Drilling fluid pressure in the wellbore overcomes the spring force to open the poppet valve and permit drilling fluid to back-flow into the casing. The regulated admission of drilling fluid into the casing permits the casing to sink into the well at a controlled rate while automatically maintaining a desired level of drilling fluid in the casing. With the casing at the bottom of the well, a cement slurry is pumped through the casing. A setting ball moving in advance of the cement slurry deactivates the poppet valve and its flapper gate and activates a second check valve in the assembly to prevent cement back-flow. The leaf spring and other components of the assembly are preferably constructed of composite materials and/or plastics that can be drilled up with polycrystalline diamond compact (PDC) bits.
