Patent CA-2498984-A1 (CA)
Title: Apparatus and method for determining the position of an elongate member of a pump assembly
Inventor: KETTLEWELL KEITH
IPC: E21B47/00
Filed: 2005-03-01
Abstract: An apparatus and method to measure the position of a portion of a pump assembly within a well particularly for use in an oil or gas well and for downhole pumps driven by a drive shaft running from a surface motor. The apparatus comprises at least one measurement device which senses the position of a portion of a pump assembly downhole. The information can be used to position a rotor of the pump assembly at an optimum position relative to a pump housing of the pump assembly to produce fluids from the well at an increased rate. Where two measurement devices are provided, they can count the number of revolutions of the drive shaft of the pump assembly at two spaced apart points. The strain or torsion within the drive shaft can then be calculated. If the torsion within the drive shaft approaches critical levels the speed of its rotation can be slowed in order to reduce the torsional strain in the drive shaft. The method and apparatus thus reduce the number of failures caused by fractured drive shafts. Since the torsion within the drive shafts can be determined, the speed of rotation of the drive shaft can be increased in normal operating conditions which allows an increased production rate from the well.

Patent CA-2508842-A1 (CA)
Inventor: MCLEOD GEORGE A
IPC: G06Q20/40
Filed: 2005-05-31
Abstract: A method of conducting cardless and cashless transactions is disclosed. A user, such as from a plurality of students of one or more clients or schools, presents a familiar user ID number and a PIN at a participating merchant. A server receives the user ID and PIN from the merchant and builds a probationary user account number from the user ID, and a client ID  associated therewith. The user ID number is padded to a greater number of digits to form the user account number to ensure it is unique amongst many users and clients at the server. Before approving the transaction, the server ascertains whether the user account number and PIN is on record and if so, then further establishes if the user has a sufficient balance in a user sub-ledger account in a source bank account corresponding with the user account number. Periodically, a settlement is made between the source account and various merchant bank accounts.

Title: Ventilation device for dehumidification
Inventor: LESTAGE MARC
IPC: F24F3/14
Filed: 2006-01-11
Abstract: The present invention relates to a ventilation device and the method of use thereof for dehumidification of residential attached or detached garages, sheds, greenhouses, RVs, motorhomes and other similar structures. This device and process uses a n extraction ventilator to dry out the structure's environment, and reduce the interior humidity using a motorized fan to expel moisture latent air out of the structure. The fan continuously runs at minimal speeds to continuously exhaust interior air and ventilate the structure, thereby controlling the garage environment, while eliminating backdrafts, and preventing animals, snow and rain from entering the structur e. The device uses a dehumidistat control to activate the fan to maximum ventilatio n capacity when the humidity reaches the set point, exhausting ambient air and extracting excess humidity from the structure. Once the humidity drops below the set point, the dehumidistat deactivates and returns the ventilator to minimum speed operator.
