Patent number: 8715465Abstract: A process for making paper, comprising contacting an anionic binder with a cationizing agent to make a cationized binder, contacting the cationized binder with an anionic pigment to form a binder/pigment agglomerate, contacting the agglomerate with an aqueous slurry of fibers, and forming a paper product from the slurry. The agglomerate may reduce the total cost of the paper product being produced while maintaining the strength of the paper at acceptable levels.Type: GrantFiled: January 13, 2010Date of Patent: May 6, 2014Assignee: Styron Europe GmbHInventors: Jouko Vyorykka, Pekka Salminen, Jonathan Budd

Patent number: 7231989Abstract: A method and a control system for controlling rock drilling. A control unit of a rock drilling apparatus is provided with one or more control modes, each determining the drilling variables to be measured, their threshold values and the operating principles according to which the operating parameters of drilling are controlled to achieve a desired control criterion.Type: GrantFiled: November 17, 2003Date of Patent: June 19, 2007Assignee: Sandvik Tamrock OyInventors: Pekka Salminen, Heikki Saha

Patent number: 7032684Abstract: A rock drill includes a string of components interconnected by screw threads and connected to a shank. A percussion piston is reciprocated against the shank during a drilling operation, while a support device applies axial support to the rear of the shank, to enhance the drilling action. When the components are being unscrewed, the percussion piston is actuated to strike the rear end of the drill string, after the support device has at least partially released the axial support of the shank, to enable tensile stress to be generated in the components by the percussive impacts to facilitate unscrewing of the components.Type: GrantFiled: June 18, 2001Date of Patent: April 25, 2006Assignee: Sandvik Intellectual Property ABInventors: Timo Muuttonen, Pekka Salminen

Patent number: 6957707Abstract: A method and a computer program for controlling a drilling cycle in a rock drilling apparatus, and a rock drilling apparatus. In accordance with the invention, each drilling unit in the rock drilling apparatus is monitored during a drilling period, and a drilling sequence of a control unit in the rock drilling apparatus is updated at predetermined intervals during the drilling period. The total time of the drilling and the time elapsed for different operations can be registered. In addition, according to an embodiment, the drilling sequence is changed during updating, if changes occur in the drilling conditions during the drilling period.Type: GrantFiled: June 3, 2004Date of Patent: October 25, 2005Assignee: Sandvik Intellectual Property ABInventors: Pertti Koivunen, Pekka Salminen

Publication number: 20030155140Abstract: The invention relates to a method of opening joints of drilling components attached to a rock drill, and to a rock drill which enabling this. According to the idea of the invention, in striking compression stress, which proceeds towards a drill bit (10), is generated in the drilling equipment (5) by striking with a percussion piston. When the drilling components are struck off, the axial bearing included in the drilling machine does not substantially support the drilling equipment, but the compression stress generated by striking is reflected from the drill bit (10) as stress of the opposite sign and generates the desired tensile stress in the drilling equipment. After striking the threaded joints of the drilling components can be opened easier by rotating the rotating device in the opposite direction.Type: ApplicationFiled: March 18, 2003Publication date: August 21, 2003Inventors: Timo Muuttonen, Pekka Salminen

Patent number: 6186246Abstract: A method for adjusting percussion pressure and a drilling machine. In the method the percussion power of a drilling machine is adjusted by moving a shank in the longitudinal direction of the drilling machine forwards when a smaller percussion power is to be transferred from the percussion piston to the shank. The drilling machine comprises at least two groups of pistons moving in the axial direction of the drilling machine, the pistons being connected to act on the shank by means of a pressure medium acting behind the pistons towards the front end of the drilling machine. The drilling machine comprises at least two separate groups of pistons whose travel with respect to one another is different and where pressure medium channels separate from one another lead to the cylinder spaces of both piston groups.Type: GrantFiled: September 4, 1998Date of Patent: February 13, 2001Assignee: Tamrock OyInventors: Timo Muuttonen, Aimo Helin, Timo Kiikka, Jorma Mäki, Pekka Salminen
