Title: Method for the production of maleic anhydride
Inventor: DUDA MARK
IPC: C07C51/215

Patent CA-2536833-A1 (CA)
Title: Power regulator for power inverter
Inventor: KOCHER MARK JOHN
IPC: H02J3/00
Filed: 2004-09-09
Abstract: A power inverter includes a regulator circuit that controls real and reactive power output by the inverter. The regulator measures real and reactive output power by calculating x-phasor components of the inverter's voltage and current output waveforms. Phasor calculation can be adapted for one or more pairs of single-phase voltages and currents. Determining the fundamental in-phase and quadrature components of output voltage and current reduces computational complexity by permitting the regulator to perform its power control processing largely in a dc signal domain, and enables separate real and reactive power control. The power inverter can include islanding detection logic, which exploits the ability to separately control reactive power. Exemplary islanding detection logic is based on determining whether changing the amount of reactive power output by the inverter induces an output frequency shift.

Patent CA-2541541-A1 (CA)
Inventor: WENZEL KENNETH H
IPC: E21B17/10
Filed: 2006-03-24
Abstract: An apparatus for keeping a down hole drilling tool vertically uses a pendulum.  The pendulum restricts flow from outlets of drilling fluid chambers providing drilling fluid to centralizer activating pistons acting upon centralizer blades. When in a concentric pivotal position, all of the drilling fluid chambers are in a balanced pressure equilibrium. Should the outer housing deviate from a vertical orientation, the pendulum swings by force of gravity to assume an angularly offset pivotal position. This relieves the flow restriction on one or two of the outlets for one or two of the drilling fluid chambers resulting in an increased flow of fluid reducing hydraulic force acting upon one or two of the pistons causing one of the centralizers to at least partially retract toward the retracted position.  Differential pressure from the other centralizers urges the outer housing back toward the vertical position until the pendulum again assumes the concentric pivotal position and the balanced pressure equilibrium in the drilling fluid chambers is restored.
Patent CA-2541784-A1 (CA)
Inventor: MARTENS HUBERT C F
IPC: G11B7/24038
Filed: 2004-10-06
Abstract: A record carrier is for recording information by writing marks in a track on a recording layer. The shortest mark used for recording the information has a length of a predefined minimum number d of channel bit lengths. The record carrier (11) has a pregroove that is modulated by a carrier pattern containing focus marks (18,19) that provides a focus area (12) at a predefined location on the recording layer. The focus marks have lengths of at least two times the length of the shortest mark for being substantially longer than the effective diameter of the scanning spot. A scanning device locates the focus area and determines the best focus offset by detecting the maximum read signal amplitude while scanning the carrier pattern.
