Abstract: A drilling apparatus includes a drill and a dust removal pipe for removing dust created in drilling from a proximity to a borehole. The drilling apparatus includes a sampling apparatus for collecting a research sample in the dust removal pipe of the drilling apparatus. The sampling apparatus includes a sampling pipe arrangement, at the end of which there is a sampling pipe, the mouth aperture of which is fitted in the dust removal pipe, element for fixing the sampling pipe arrangement to the dust removal pipe, a suction device for forming suction in the sampling pipe, and a collecting arrangement fixed to the sampling pipe arrangement for separating sampling material from air flowing in the sampling pipe arrangement, and for collecting sampling material. The sampling apparatus includes a length adjustment apparatus for moving the sampling pipe in the longitudinal direction in the dust removal pipe, and a rotating apparatus for rotating the sampling pipe in the dust removal pipe.

Abstract: A sampling apparatus for collecting geological samples from the subsurface is fixable to a drill, such as to a mining drill rig. The drill apparatus includes a chassis, and a drill comprising a boring pipe and a drill bit. The sampling apparatus is fixable to the chassis of the drill apparatus and includes a sampling pipe arrangement to be fitted to the end of it, as well as a collecting apparatus to be connected to the sampling pipe apparatus, in which the collecting apparatus samples can be collected. The nozzle is a suction nozzle, in which suction is arranged. The sampling pipe arrangement comprises an attitude adjustment apparatus, with which the nozzle can be arranged into the proximity of the boring pipe in such a way that the nozzle is near the borehole and the mouth of it is directed towards the borehole such that it is able to take samples directly from the mantle rock flying out from the borehole.

Abstract: Elevator, which includes a guide rail line, which includes a plurality of consecutive guide rails, which are supported on the building with guide rail brackets fixed to the building, which guide rail brackets comprise a frame, a mounting base and structure for pressing the guide rail against the mounting base, which guide rail bracket essentially prevents at its point lateral movement of the guide rail in relation to the fixing point of the guide rail bracket and permits longitudinal movement of the guide rail in relation to the fixing point of the guide rail bracket. The aforementioned mounting base is fixed to the frame of the guide rail bracket movably in the longitudinal direction of the guide rail.
