Patent CA-2592915-A1 (CA)
Inventor: WESTIN GUNNAR
IPC: C04B35/117
Filed: 2006-01-03
Abstract: A novel solution route has been developed that after heat-treatment to 500-600~C under inert atmosphere, yields highly porous composites of nano-sized metal (Ni) particle inclusions in ceramics (Al2O3). Metal loadings could be made from < 1% to >95% Ni. The metal inclusion sizes in the Ni-Al2O3 system with the 10 atom% Ni sample were 4-7 nm, while for the 75 atom% Ni sample they were 5-8 nm. It was shown that the 10 atom% Ni sample could be used as a catalyst for the conversion of CO2 and CH4 in the temperature range 550-700~C, while higher temperatures led to growth of the Ni particles and carbon poisoning over time. The solution routes could also be deposited as thin dense films containing <10 nm Ni particles. Such films with high Ni-particle loadings deposited on aluminium substrates have shown very good solar heat absorber proficiency and provide good substrates for carbon tube growth.

Title: System and method for actuating wellbore tools
Inventor: ELLIS DUSTIN
IPC: E21B33/04
Filed: 2006-06-30
Abstract: An actuator (100) operatively coupled to a wellbore tool is activated upon receiving fluid that a predetermined applied pressure . When the fluid string reaches the predetermined applied pressure, the actuator undertakes a specified action such as longitudinal movement, rotation, expansion, etc. that actuates or operates the wellbore tool . Premature actuation of the wellbore tool is prevented by applying a resistive force to the actuator that, alone or in cooperation with another mechanism, arrests movement of the actuator. This resistive force is generated by applied pressure of the fluid in the work string.

Title: System and method for selective encryption of input data during a retail transaction
Inventor: WESTON TIMOTHY M
IPC: G07F7/10
Filed: 2006-07-19
Abstract: A retail environment having retail terminals with data entry point devices selectively encrypts input received by the data entry point devices and passes the encrypted data to a security module.
