Abstract: The object of the invention is a method in the installation of an elevator, said elevator being provided with an elevator car traveling in a controlled manner along guide rails in an elevator hoistway, for determining the disposal location of the hoistway components to be disposed in the elevator hoistway and/or the landing doors of the elevator. The disposal location of the hoistway components and/or of the landing doors of the elevator is determined in relation to the guide rails of the elevator car by copying the disposal location at different heights in the elevator hoistway mechanically by means of a tool, in which tool the disposal locations according to plan of the hoistway components are arranged to remain fixed for essentially at least the whole period of the aforementioned determination of the disposal locations of the hoistway components of the elevator hoistway and/or of the landing doors of the elevator. The object of the invention is also a tool to be used in the method.

Abstract: 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.

Abstract: The invention relates to a method in a delimbing device (1), which delimbing device (1) comprises a frame structure (2), at least one supporting means (3a, 3b, 3c) attached in the frame structure (2) in a movable (5a, 5b, 5c) manner to support the tree-truck (S) and to exert a first force effect (F0) on the tree-trunk (S), actuator means (9) to control the position of the supporting means (3a, 3b, 3c) to maintain the first force effect (F0) exerted by the supporting means (3a, 3b, 3c) on the tree-trunk (S). In the method the second force effect (F) exerted by the tree-trunk (S) to the frame structure (2) is measured with sensor means (12) arranged in connection with the frame structure (2) and to change the second force effect (F), the first force effect (F0) is adjusted by utilizing the information obtained from the measurement.
