Abstract: The present invention relates to a compensating method applicable to vehicles having a lifting device made up of a mast (4) and vertically adjustable load carrier (5) provided on the mast. The method is for compensating departures in the position of loads (8, 9), preferably goods on loading stools or pallets, on the load carrier (5) relative to a frame (2) of a wheel driver vehicle (1). Loads (8, 9) of different weight when lifted to various heights deflect the mast (4) outwards in various degrees from an unloaded position. The vehicle (1) is adapted to repeatedly deliver loads (8, 9) on the load carrier (5) at different levels (12, 13, 14) in a storage system (11) and in predetermined delivering positions (P3) on each such level (12, 13, 14). A drive-up length (L.sub.o) corresponding to moving the vehicle (1) without a load (8, 9) from a reference point (R2) to a delivering position (P2) has been determined. In order to provide quick and safe compensation of deflections, the invention determines the size (.

Abstract: The present invention relates to a method for fine positioning vehicles in exact relationships to geographic reference markings, whereby the vehicle (1) is adapted to fetch and deliver loads (2) preferably goods carried on loading stools or pallets, at fetching and delivering points (3-14), whereby it is required that the vehicle (1) repeatedly may be brought to exact positions relative to said fetching and delivering points (3-14) and whereby the vehicle (1) has at least one indicating and calculating device (24) for indicating the distance between two non-parallel lines (39-40) of the geographic reference markings (36) for calculating whether the vehicle (1) is on one side or the other of a certain relationship to a predetermined line (33 and/or 34) of direction of movement by indicating whether the distance measures between said lines (39, 40) of the reference marking is greater or smaller than the distance representing said certain relationship to the predetermined line (33 and/or 34) of direction of move

Abstract: The invention relates to a portable, battery-driven device for measuring heat transfer coefficients (k-values). It uses an amplifier (1), which forms the quotient between the inner temperature minus the inner wall temperature on one hand and the inner temperature minus the outer temperature on the other hand. The temperature values of the first-mentioned substraction are obtained by thermal elements (7, 8), which are connected to the device. The difference according to the second one of the substractions is adjustable connected in a feed back circuit of the amplifier (1). The output quantity of the latter is supplied to an instrument (3) graduated in k-value. The thermal element for the measuring of the inner wall temperature can be provided at the tip of a probe (9), and may consequently be conveniently applied to different places of a wall to be investigated.
