Patent CA-2414091-C (CA)
Inventor: MUUTTONEN TIMO
IPC: E21B19/16
Filed: 2001-06-18
Granted: 2009-09-08
Abstract: 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.

Abstract: A system provides monitoring/feedback to a transportation vehicle regarding the state of that vehicle based on, at least, information provided by sensors located on or in the transportation vehicle. Monitoring the transportation vehicle provides information about the status of the transportation vehicle and equipment on or in the vehicle. Feedback information is provided to the transportation vehicle based on the information received during monitoring.  Additionally, feedback information may be formulated based on additional criteria received from equipment other than the sensors located on or in the vehicle, for example, meteorological systems, geographic location systems, e.g., a radar system, a global positioning system, etc. The information provided by the sensors and the formulated feedback information may be stored in memory on the transportation vehicle as well as at a stable location for archiving and subsequent analysis.

Granted: 2012-01-03
Abstract: The pressure sensor comprises two supporting bodies (10,11) with plane supporting surfaces (12,13) between which a hose (14) is flattened. For measuring the internal pressure of the hose (14), a web (17) displaceable in a gap (16) is arranged at a supporting body (10), said web pressing against the plane surface of the flattened hose (14) and being supported on a force sensor (19). Thus, the deformation forces generated upon compressing the hose are eliminated for the measurement of pressure.
