20100319866 | MEASURING OF WEB - Optical radiation sources functioning on different optical bands radiate on different optical bands and focus optical radiation on a region in a web surface as pulses in such a manner that illumination areas of the pulses overlap on the plane of the web. At most one optical radiation band is focused on the web from the direction of the normal. The spatial intensity distribution of at least one optical band differs from the uniform distribution and the intensity distributions of at least two different optical bands differ from one another in a predetermined manner. A camera forms still images of the web surface region on each optical radiation band. An image-processing unit determines the surface topography of the web on the basis of the images. In addition, a controller may control the paper manufacturing process on the basis of the determined surface topography. | 12-23-2010 |

20130008716 | Rock Drilling Rig and Method for Positioning the Same - The invention relates to method for positioning a rock drilling rig and to a rock drilling rig. The rock drilling rig is moved using combustion-engine-free drive equipment with an electric drive motor. The torque is transmitted from the drive motor to the traction wheels over a mechanical anti-slip transmission connection. The ratio between the drive motor rotation rate and the traction wheel rotation rate is kept constantly the same during positioning. The drive motor is not only used for moving but also for stopping. | 01-10-2013 |
20130056271 | ROCK DRILLING RIG, METHOD FOR CONTROLLING THE TEMPERATURE OF ITS DRIVE EQUIPMENT, AND LIQUID COOLING SYSTEM - The invention relates to a rock drilling rig, a method for controlling the temperature of its drive equipment, and a liquid cooling system. The rock drilling rig includes combustion-engine-free drive equipment, which includes electric components for affecting transfer drive. The rock drilling rig is also provided with a liquid cooling system, to which one or more electric components affecting the transfer drive are connected to be cooled by the system. The cooling of the components is controlled by a control unit according to a strategy set therein. The cooling system may additionally be precooled before the transfer drive. | 03-07-2013 |
20130056279 | ROCK DRILLING RIG AND METHOD FOR DOWNHILL DRIVE - The invention relates to a rock drilling rig and a method for downhill driving of a rock drilling rig. The rock drilling rig comprises electric drive equipment, the drive motor of which serves as a primary brake in long-term downhill driving. The drive motor thus converts kinetic energy into electric energy, with which an energy storage is charged. To consume surplus electric energy, a hydraulic system or a compressed air system is turned on. A hydraulic pump and a compressor ( | 03-07-2013 |
