Title: Drilling assembly with a steering device for coiled-tubing operations
Inventor: KRUSPE THOMAS
IPC: E21B7/08
Filed: 1998-01-29
Abstract: The present invention provides a coiled tubing conveyed drilling assembly for drilling deviated wellbores. The drilling assembly includes a drill bit at the lower end of the drilling assembly. A drilling motor provides the rotary power to the drill bit. A bearing assembly of the drilling motor provides lateral and axial support to the drill shaft connected to the drill bit. A  steering device is integrated into drilling motor assembly. The steering device contains a plurality of force application members disposed at an outer surface of the drilling motor assembly. Each force application member is adapted to move between a normal position and a radially extended position to exert force on the wellbore interior when in extended position. A power unit in the housing provides pressurized fluid to the force application members. A control device for independently operating each of the force application members is disposed in the drilling motor assembly. A control circuit or unit independently controls the operation of the control device to independently control each force application member. For short radius drilling, a knuckle joint is disposed uphole of the steering device to provide a bend in the drilling assembly. During drilling of a wellbore, the force application members are operated to adjust the force on the wellbore to drill the wellbore in the desired direction.

Patent CA-2282080-A1 (CA)
Inventor: CHARASSE HELEN
IPC: B65B9/02
Filed: 1998-11-24
Abstract: The invention concerns a continuous packaging technique whereby a volume of compressible material is compressed between two convergent conveyors, the volume being initially placed and driven during the compression between two continuous packaging film strips, mutually linked on either side of the volume once the required degree of compression has been reached. The invention is characterised in that after having left between two consecutive volumes a length L of packaging film on each strip, the distance between the rear end of a first volume and the front end of the next volume is adjusted such that it is equal to the length L at the time when the two strips are mutually tied in the packaging step. The invention is useful for conditioning insulating products based on mineral wool.

Title: Package for safe storage of electrophilic fluorinating agent
Inventor: SYVRET ROBERT GEORGE
IPC: C07B63/00
Filed: 1999-09-22
Abstract: An economical means of safely "containing" or "packaging" commercial electrophilic fluorination agents whereby these agents are readily stored and transported in a package, typically without loss of "F+" activity, and in a form which is readily and directly useable, i.e., in solution or a slurry. Importantly, the solution/slurry medium provides a tremendous safety margin for storage and transportation since the solution medium has an enormous ability to absorb heat (due to the latent heat of vaporization of the liquid) relative to the contained active fluorination agent.

Title: Financing method and financial structure
Inventor: MOORE MICHAEL D
IPC: G06Q30/06
Filed: 1999-10-29
Abstract: A financing method and financial structure is provided for funding development of products where a purchaser has contractually agreed to purchase a quantity of that product, at agreed pricing for an agreed term. The supplier sells the assets required to produce the product to a financing entity who then implements a lease of those assets back to the supplier. The lease amount received by the supplier can substantially offset the development costs, removing the impact of these costs from the balance sheet of the supplier. The lease can also provides interest-only payments for a first term, wherein full production of the product is not yet occurring and interest and principal payments for a second term wherein full production is occurring and larger revenues are being received to fund the larger lease payments. The financing entity can be the combination of a leasing entity and a lending entity to fund the lease entity, or it can be a lending entity who has sufficient leasing expertise.

Title: Evaporator for the treatment of honey bee diseases & undesirable hive conditions
Inventor: RUDIAK RONALD PAUL
IPC: A01K51/00
Filed: 2000-01-17
Abstract: An evaporator which provides formic acid vapour at a consistent and repeatable rate for effective treatment of varroatosis in honey bees. The evaporation chamber is heated by an electrical element(s) and maintained at a constant temperature by a mechanical thermostat or electronic control circuit. The amount of vaporised material is controlled by adjusting the temperature setting and metering apertures of the evaporation chamber. A continuous flow of formic acid vapour has been demonstrated to kill tracheal and varroa mites much more effectively than other methods and systems, now in use, which depend primarily on the amount of heat generated within the hive as well as solar radiation and ambient temperatures for their operation. The evaporator is made using materials which are largely unaffected by corrosive chemicals, such as formic acid. All electrical components are protected from moisture and corrosion with a protective coating.
