Abstract: A device for winding up long flexible materials, such as electrical cables, ropes, fluid lines, or the like, consists of a drum (3) that is designed to gather the material through rotation around a geometric axle on the supporting pieces (9). The holders (8, 10) are positioned on both sides of the drum to prevent the material from slipping off the drum (3) during winding in the direction of the axle, whereby the first holder (8) on one side of the drum is positioned on the drum. In this device, the first holders (10) are arranged as such that they can shift between an active holding position, where they extend out past the drum's support pieces (9), and an inactive position, where they allow the coiled material to be taken off the drum (3) from this respective side. This is possible as the holders (10) are attached to a control (11) rotationally positioned around a geometric axle essentially parallel to the drum's geometric axle in relation to the drum's frame, which is designed, depending on which direction it is turned in relation to the drum's frame, to bring the holders (10) from the active position to the inactive position and vice-versa through said rotation.<IMAGE>

Abstract: A rearview mirror for passenger vehicles has a primary viewing surface that is substantially flat. This surface curves to the rear of the mirror, with a continuously decreasing radius of curvature, toward at least one lateral edge thereof. This provides peripheral vision to the operator of a vehicle in addition to this vision directly to the rear. The peripheral vision introduces a very gradually increasing rate of distortion as the reflected image approaches the edge of vision. This causes the peripherally reflected images to be easily relatable to those reflected from the primary viewing surface.

Abstract: An end wall (1b) is provided with bosses (15) extending beyond its plane, by means of which bosses a first wall section may be snapped into engagement with one or more other wall sections which display edges embracing the first wall section. Recesses corresponding to these bosses are disposed on the insides of the latter edges. Each respective boss is connected to a manually operative section (6) which is disposed in a depression (7) on the outside of the first wall section. On raising of each respective manual section from its associated recess, the associated boss is released from engagement with its corresponding recess. The bosses, with their associated manually operable sections, are disposed pairwise in differing spaced-apart relationship from, for example a bottom edge (8). Each respective pair of bosses and manually operative sections is disposed on the side edges (9, 10) of the first wall section. The wall section is arranged to permit folding-out of an exposed or disengaged wall section in relation to unexposed or engaged wall sections, according as disengagement is affected of each respective pair of bosses by means of the manually operative sections.

Abstract: Aqueous suspensions of papermaking fibres and filler are each separately treated with an anionic or a cationic polymer, after which the filler (preferably) or the papermaking fibre is treated with a polymer of opposite charge to that used in the initial treatment. The filler and papermaking suspensions are then mixed to form a papermaking stock, with dilution as necessary before, during or after the mixing operation. This stock is then used to form a loaded paper web in conventional manner. The initial treating polymer is preferably a papermaking retention aid or flocculant, e.g. a cationic polyacrylamide or an amine/amide/epichlorohydrin copolymer in the case of cationic materials or an anionic polyacrylamide in the case of anionic materials. The further treating polymer is preferably an anionic or cationic starch, depending on the charge of the initial treating polymer.

Abstract: The invention is for a flat electrical heating resistance element, so called foil elements. Elements according to the invention can be used for many purposes, however, it is specially intended for use as heating elements for water beds. The object of the invention is to minimize the electromagnetic fields caused by the elements. The influence of such magnetic fields on humans is on the whole unknown why there is a common desire that the strength of these magnetic fields shall be as low as possible in order to minimize effects, if any. Heating elements according to the invention have electrical resistance wire or band placed in loops on a plastic foil surface, whereby the loops have four with each other parallel conductors, electrically connected so that in any given moment the direction of the current in the two outer conductors are in the same direction and in the two inner conductors in the same direction opposite to the outer conductors.

Abstract: The invention relates to an arrangement for injecting faults into electronic components. In order to check that fault-tolerant systems actually can tolerate internal faults, faults must be created in or injected into the components of the system under circumstances corresponding to normal operation. Fault injection trials are usually carried out only in a laboratory environment because trials in the field are rendered more difficult by the fact that a extensive apparatus has to be taken along. The invention solves this problem by producing a complete fault-injection arrangement by making it possible for the arrangement, together with the component into which faults are to be injected, to be positioned in the usual position of the component in the electronic system. The arrangement can consist of a miniature vacuum chamber containing a radiation source 1 and an irradiated component 2. The electrical connections 4 of the irradiated component have been extended through the bottom plate 5 of the vacuum chamber. <IMAGE>

Abstract: The invention relates to a process for collecting trees with the aid of a tree felling machine comprising an upper and a lower gripping tool 3,4 and a cutting device 14 mounted on a frame 2. The machine is made to approach the first tree with both its gripping tools 3,4 open, after which the tree is embraced by the gripping tools closing on it, followed by a cutting action. The machine is then driven to another tree. With each new tree after the first one, the lower gripping tool 4 is opened to receive the new tree while the previously felled tree is held tight only by the upper gripping tool 3. The lower gripping tool 4 is then closed around the tree whilst the new tree is pressed against the outside of the upper gripping tool 3. The upper gripping tool is then opened, and all the trees are held by both gripping tools. During this opening movement of the upper gripping tool 3, each tree after the first one is moved backward, i.e. in the direction away from the new tree relative to the lower gripping tool 4. <IMAGE>

According to the invention, a line (14) is connected between the junction points of the inverter pairs on the direct current side, and the alternating current outputs of the auxiliary inverters are each connected to a respective primary winding on a transformer (12). When one of the main inverters drops out, this enables power to be transferred to remaining main inverters through the medium of the parallel auxiliary inverters and the transformer, so as to provide emergency power. <IMAGE>

According to the method, the side location of the other vehicle and one's own vehicle is determined at a position where the other vehicle is level with one's own vehicle, by moving the front vehicle backwards in time and/or moving the rear vehicle forwards in time, on the basis of position measurements of the position of the other vehicle. The side location of the other vehicle is compared with the side location of one's own vehicle, by which a measure of the discrepancy between the course of the other vehicle and the course of one's own vehicle is obtained. According to the invention, the position where the other vehicle is level with one's own vehicle may be determined on the basis of the inertial speed vector of the other vehicle at one or more points in time.
