Patent CA-2431824-A1 (CA)
Title: Continuous feed drilling system
Inventor: SILAY LOUIS E
IPC: E21B19/086
Filed: 2003-06-11
Abstract: A continuous feed drilling system and controller includes a head assembly having first and second chucks synchronized to rotate at the same rotational velocity. The chucks are independently moveable within the head assembly and their positions are measured by linear transducers. The controller causes the first chuck to engage with a drill stem and begin rotating and advancing. The controller uses the outputs of the linear transducers to determine the linear velocity of the advancing first chuck and synchronize the linear velocity of the first and second chucks. The controller then causes the second chuck to engage the drill stem and causes the first chuck to release the drill stem. The process is repeated, alternating the roles of the first and second chucks, thus creating a continuous drilling motion.

Patent CA-2435397-A1 (CA)
Inventor: OLSEN ALDEN W
IPC: C09K5/20
Filed: 2002-05-08
Abstract: The present invention relates to a monocarboxylic acid based antifreeze coolant formulation for applications such as for gasoline engines which may be used for inhibition and prevention erosion and corrosion of aluminum and the corrosion of other metals exposed to an aqueous liquid in automotive coolant systems. The formulation further inhibits mineral scale. It may be packaged as an ethylene glycol based additive for use in new engines or in a concentrated inhibition package as an additive as for reinhibition of used coolant. The combination of a mixture of ethylene or propylene glycol, a monobasic carboxylic organic acid, azoles, and low levels of molybdates provides corrosion resistance. A heavy duty formula more suited for diesel engines also contains a nitrite salt and/or nitrate salt and a siloxane stabilized silicate, and combinations thereof to provide a synergistic protective effect against the cavitation corrosion of aluminum in aqueous liquids reducing the corrosion rate and is effective at relatively low concentrations varying pH  ranges.

Title: Superior liner
Inventor: CYR GERARD L
IPC: B23K9/12
Filed: 2003-06-05
Abstract: A liner for a Mig or wire welding gun is a consumable round tube or coil shaped extension spring inserted inside a Mig Welding gun designed to stop the wear of the expensive Mig Welding gun while simultaneously reducing the friction or drag of the Mig Welding consumable wire as it passes through the Mig Welding gun. The first 3 to C6 feet of the Mig welding liner is normally encapsulated in a shrink-wrap plastic coating to help direct the flow of the Mig Welding shielding gas. There are several different inside diameter shapes and materials of liner surface that the Mig Welding wire rides on in an attempt to facilitate these requirements but they are all closed tube extension coil spring shape. All types of continuous wire welding applications will benefit from this invention.

Patent CA-2473868-A1 (CA)
Inventor: STEARNS DAVID N
IPC: A01G13/02
Filed: 2003-01-13
Abstract: The novel seedling bud capping device is easily deployed on a bud of a seedling due to the use of adherent on either edge (rather than a staple), and more particularly due to its predefinedly selective use of adherent to form an inverted conic space around the bud for receiving sunlight and for capturing the bud stem near its base. The paper stock or the adherent used in the bud capping device may be impregnated with a repellent scent to further ward away browsers to protect the seedling. Preferably, the bud capping device is maade from a small, e.g. ~5 inch, square piece of water-repellent paper stock having a layer of glue adjacent at least one edge. The stock is prootected on the adherent side by another layer of material to be selectively removed. This protective layer is scored and a free segment of the protective backing layer is removed to expose a region of adherent. Because the adherent is wider at the base than at the top, when the devid is deployed near a terminus of a seedling bud, it grasps the base of the bud'sstem at a fulcrum of an inverted cone while leaving open the top of the device for exposure to sunlight. The bud capping device prevents browsing of a fragile seedling while permitting the seedling to thrive. The bud capping device may be affixed with a pull-tab scent device of any suitable configuration, preferably with a slow-release animal repellent. The device may be arranged and mass-produced in laminar sheets, cut and formed into rolls for easy dispensing.
