Patent number: 7802655Abstract: A solid composition stick applicator is provided. The applicator comprises an applicator body having a first and second end, the second end having an opening through which a solid composition stick is dispensed. Within the applicator is housed a helical tension spring having a first spring end and a second spring end, the first spring end, second spring end, or both the first and second spring end held at a fixed position with respect to the applicator body. The helical tension spring is wound around a guide system that is housed within the applicator body. A pushing assembly is attached to the helical tension spring and the pushing assembly is movable from a first position at or near the first end of the applicator body, to a second position at or near the second end of the applicator body. Tension within the helical tension spring is greater in the first position than in the second position thereby urging the pushing assembly towards the second end of the applicator body.Type: GrantFiled: September 8, 2004Date of Patent: September 28, 2010Assignee: Kelsan Technologies Corp.Inventors: Jonathan de Wet, Ron C.

Publication number: 20070272486Abstract: A method for applying a liquid composition to a rail surface is provided. This method involves supplying a liquid composition in one or more reservoirs on a rail car (revenue generating car), and applying the liquid composition from the one or more reservoirs to the rail surface. A liquid composition application system is also provided. The liquid composition application system includes a reservoir(s) for holding a liquid composition mounted on a rail car. A pipe is connected to the reservoir(s), and a pump, for moving the liquid composition from the reservoir(s) to a dispensing nozzle(s), is provided. A controller processes topological information, data from the liquid composition application system, or both. The application of the liquid composition may be monitored and controlled from a remote site separate from the rail car.Type: ApplicationFiled: June 27, 2005Publication date: November 29, 2007Applicant: KELSAN TECHNOLOGIES CORP.Inventors: Don Eadie, John Cotter, Dave Elvidge

Patent number: 7244695Abstract: According to the invention there is provided a method of reducing wear of one or both of two steel elements having surfaces in sliding or sliding-rolling contact. The method involves applying an HPF friction control composition to one, or more than one contacting surface of one or both of the two steel elements. In a particular example, the HPF friction control composition comprises a rheological control agent, a lubricant, a friction modifier, and one, or more than one of a retentivity agent, an antioxidant, a consistency modifier, and a freezing point depressant.Type: GrantFiled: May 2, 2003Date of Patent: July 17, 2007Assignee: Kelsan Technologies Corp.Inventor: Don T.

Publication number: 20060264336Abstract: The present invention provides a modified interlocking solid composition stick for applying to steel surfaces that are in sliding or rolling-sliding contact. The modified stick comprises a body member with four sides, a first end and an opposed second end, and a nib member attached to the first end of the body member, the nib member having four sides connected by substantially curved side edges. The second end of the body member contains a cavity with substantially curved sidewalls dimensioned to snugly receive a nib member of a corresponding interlocking solid stick. To reduce the likelihood of failure of the nib or cavity, the dimensions of the nib are optimized such that a length of one side of the nib member (nl) and a length of the side of the body member (l) in the same plane have a ratio nl/l from about 0.6 to about 0.75.Type: ApplicationFiled: May 4, 2005Publication date: November 23, 2006Applicant: Kelsan Technologies Corp.Inventor: Ron Hui

Patent number: 6854908Abstract: An applicator for a circular arc-shaped solid composition comprises a housing defining a conduit that is sized to accept the circular arc-shaped solid composition stick. The conduit has a first end and a second end, the second end being open, and has a continuous circular arc-shape from the first end to the second end. The housing also contains one, or more than one opening for engaging a fastener. Each one of the one, or more than one opening is of a sufficient size to permit at least partial lateral movement of the fastener. Also included in the housing are an inlet and an outlet in communication with the conduit, the outlet being in communication with the second end, and a biasing assembly for advancing the circular arc-shaped solid composition stick within the conduit. The position of the applicator of the present invention relative to a surface to be treated can be easily adjusted by laterally sliding the housing of the applicator relative to its mounting bracket.Type: GrantFiled: March 14, 2003Date of Patent: February 15, 2005Assignee: Kelsan Technologies Corp.Inventors: Ron C.
