Patent CA-2471155-A1 (CA)
Title: Improved internal breaker
Inventor: SAWDON CHRISTOPHER ALAN
IPC: C09K8/74
Filed: 2002-12-18
Abstract: A wellbore fluid including a peroxide degradable polymer and an encapsulated peroxide source. The peroxide degradable polymer may be a polysaccharide. Th e peroxide source may include an inorganic peroxide, including zinc and alkali ne earth metal peroxides, such as magnesium peroxide. The encapsulating materia l may be a polymer, including enteric polymers. The release of peroxide, from peroxide sources generally, can be controlled by means of pH such that peroxide source can be activated, and peroxide released, by a change in pH. In a wellbore, this pH change can be effected by using produced fluids to lower the pH of a more basic wellbore fluid.

Title: Initiating connections through firewalls and network address translators
Inventor: HUITEMA CHRISTIAN
IPC: H04L12/46
Filed: 2003-01-15
Abstract: Access to private devices (220) that are separated from the public network by firewalls (222) and network address translators (NATs) is provided without reconfiguring the firewalls and NATs. A private device wishing to provide access to external devices (240) establishes a virtual private pipe (226) to a secure hub (200), which includes functionality to terminate virtual pipes and to switch communications between these pipes and the public network (112). The secure hub assigns a secondary IP address to the private device/pipe and thereby provides the private device with a network appearance that is now beyond the firewall/NAT. External devices access the private device by addressing communications to the secondary IP address, which communications are routed to the secure hub and tunneled through the pipe to the private device. The private device can also restrict access through an access control list that is enforced by the secure hub.

Title: Process for the production of acetic acid
Inventor: MUSKETT MICHAEL JAMES
IPC: C07C51/42
Filed: 2003-04-09
Abstract: A process for the production of acetic acid which comprises carbonylating methanol and/or a reactive derivative thereof in one or more reactors in a liquid reaction composition comprising iridium carbonylation catalyst, ruthenium promoter, methyl iodide co-catalyst, methyl acetate, acetic acid and water. The liquid reaction composition from the one or more reactors is passed to one or more flash separation stages to form (i) a vapour fraction comprising condensable components and a low pressure off-gas comprising carbon monoxide and (ii) a liquid fraction comprising iridium carbonylation catalyst, ruthenium promoter and acetic acid solvent. The condensable components are separated from the low pressure off-gas. The concentration of carbon monoxide in the low pressure off-gas is maintained according to the formula: Y>mX+C  wherein Y is the molar concentration of carbon monoxide in the low pressure off-gas, X is the concentration in ppm by weight of ruthenium in the liquid reaction composition, m is about 0.012 and C is about -8.7.
Patent CA-2482981-A1 (CA)
Title: Stabilizing collar for a concrete saw blade
Inventor: VIDMOR DAVID L
IPC: B28D1/04
Filed: 2003-04-23
Abstract: A stabilizing collar for a concrete saw blade provides a rigid blade structure for smoother cutting operations, particularly in partially cured concrete. A  pair of the present collars (10a, 10b) are secured to the blade shaft on each side of the blade, clamping the blade securely therebetween. Each collar has a slightly recessed central area and a raised toroidal rim therearound. Clamping the blade and collar assembly tightly on the shaft, compresses the recessed areas and clamps the rim portions of the collars tightly against the blade at some distance outward from the shaft, thereby providing a rigid assembly and essentially eliminating lateral vibration and flexing of the blade. This enables an otherwise conventional concrete saw to be used for cutting "green"  concrete, i. e. relatively soft concrete which has only partially cured.

Title: The use of state-change materials in reformable shapes, templates or tooling
Inventor: JACOBSON THEODORE L
IPC: B29C33/40
Filed: 2002-05-17
Abstract: Techniques for generating a stable, force-resisting positive or negative representation of a shape. A state-changeable mixture (35) comprises uniform, generally ordered, closely-spaced bodies (8) and a liquid carrier medium (9) of relatively similar density, with the liquid medium (9) filing any voids or interstices (23) between the bodies (8) and excluding air or gas bubbles from the mixture (35). Within the mixture (35), the solid bodies (8) can be caused to transition from a near-liquid or fluent condition of mobility to a stable, force-resisting condition through introduction and then extraction of a slight excess quantity of the carrier medium (9). To create mobility, this excess quantity or transition liquid (10) is introduced to create a fluent condition by providing a slight clearance (23) between the bodies (8) which permits the gently-forced introduction of at least two simultaneous slip planes between ordered bulk masses of the bodies (8) at any point in the mixture (35).  Transition to the stable condition is caused by extraction of the transition liquid (10), removing the clearance between bodies (8) and causing them to make stable, consolidated contact.
