Patent number: 7575710Abstract: A gas flow control system for a gas fuelled torch including four gas passages controlled by four on-off valves and a control device. The control device can be used to actuate the valves in different combinations, thereby shutting off both fuel and oxygen flows, or allowing a full rate of fuel and oxygen flows for operational performances, or allowing only a restricted rate of fuel and oxygen flows for a pilot flame of the torch.Type: GrantFiled: March 2, 2007Date of Patent: August 18, 2009Inventor: Claude Bissonnette

Publication number: 20050098236Abstract: A steel cutting apparatus includes a cutting torch that is moved in an arcuate path of constant radius so that a cutting flame of the cutting torch is always aimed at a fixed point in relation to a strand of steel at a cutting plane. Molten steel and iron oxide flow through a kerf in the steel toward a bottom corner of the strand, that is a center of the arcuate path. The rate of advance of the cutting torch along the arcuate path is controlled to compensate for at least a length of the path. The temperature of the strand in the path of the cutting flame, any edge of the strand in the path of the cutting flame, and a time remaining for cutting the strand can also be factors that influence the variable rate of advance of the cutting torch.Type: ApplicationFiled: November 10, 2003Publication date: May 12, 2005Inventor: Claude Bissonnette

Patent number: 6786979Abstract: A steel cutting apparatus includes a cutting torch that is moved in an arcuate path for guiding the cutting torch so that a cutting flame of the cutting torch is always aimed at a bottom corner of the steel at the side where the cutting process begins. Molten steel and iron oxide flow through a kerf in the steel toward the bottom corner, and drop away from the billet for collection and disposal. Only a very small amount of slag adheres to the bottom corner of the billet when cutting is complete.Type: GrantFiled: October 15, 2003Date of Patent: September 7, 2004Assignee: Oxy-Arc International, Inc.Inventor: Claude Bissonnette

Patent number: 6277323Abstract: A novel cutting nozzle assembly for a postmixed oxygen-fuel gas torch is disclosed. The nozzle assembly includes a cylindrical shroud which surrounds and extends away from the gas discharge orifices in the gas discharge end of the cutting nozzle. The cylindrical shroud has the advantage of producing a tighter gas stream and of promoting a more thorough mixing of the preheat oxygen and the fuel gas to provide a hotter, more compact flame which produces a more parallel-sided cut through metal workpieces. The cutting tip therefore conserves metal as well as cutting gases. It also cuts faster than prior art postmixed cutting nozzles.Type: GrantFiled: July 7, 1999Date of Patent: August 21, 2001Assignee: Oxy-Arc International Inc.Inventor: Claude Bissonnette

Patent number: 5885139Abstract: A power-operated and hand steerable machine for stripping linoleum, tile, mastic, grout, adhesive and the like from a floor and also for re-surfacing the floor after the stripping operation. The machine includes a support frame, a drive plate driven by a motor about a vertical rotational axis, a reversible work plate mounted under the drive plate and carrying cutter blocks with cutter inserts at one face and abrasive-carrying devices at the opposite face. Therefore, after a floor stripping operation by the cutter inserts, the work plate can be reversed and a floor re-surfacing operation be carried out by using the abrasive-carrying devices. A change speed system enables to drive the work plate at a higher speed during floor re-surfacing than during floor stripping. Longitudinally adjustable weights are carried by the support frame to adjustably bias the work plate against the floor.Type: GrantFiled: July 15, 1997Date of Patent: March 23, 1999Inventors: Francois Lemieux, Claude Bissonnette

Patent number: 5383650Abstract: A novel gas flow control assembly for a gas fuel cutting torch is disclosed. The gas flow control assembly provides a gas-saving oxy/fuel cutting torch which may be operated in a pilot mode when the torch is not in active use. The gas flow control assembly includes an inlet end and an outlet end. The inlet end is adapted for the attachment of a fuel gas conduit and an oxygen conduit. The outlet end is adapted for the attachment of a fuel gas tube, a preheat oxygen tube and a cutting oxygen tube which provide fluid communication of fuel gas, preheat oxygen and cutting oxygen from the control body to a torch head. Passages through the control body are normally closed by biased valves having stems which extend through fluid tight seals in a top of the control body. A lever pivotally connected to the control body is arranged to simultaneously depress the stems of the valves which normally close the preheat oxygen and the fuel gas passages when the lever is manually operated to a first position.Type: GrantFiled: February 4, 1994Date of Patent: January 24, 1995Inventor: Claude Bissonnette

Patent number: 5120026Abstract: A fluid cooled cutting torch includes a hollow handle, a torch butt assembly, a torch head, supply tubes for preheat gas, preheat oxygen and cutting oxygen and cooling fluid supply and drainage conduits. The torch head is adapted to interchangeably receive a premix or postmix cutting torch nozzle. The cooling supply conduit extends through the torch butt assembly and within the torch handle to a point adjacent the torch head. The cooling system provides effective cooling of the torch head and even cooling of the torch handle. The torch is easily manufactured at low cost. The torch may be readily converted from a premix torch to a postmix torch.Type: GrantFiled: November 14, 1990Date of Patent: June 9, 1992Inventor: Claude Bissonnette
