Abstract: To produce wooden laths, boards of optional width are resawn in unplaned condition, whereupon the laths are fed each into one compartment which is defined by splitting knives and within which the laths are subjected to a pressure which is directed against the feed table carrying the laths and under the action of which first the lower side and then the upper side are planed. The machine for resawing the boards and planing the laths has a feed table with a guide edge and sawing means comprising coaxially mounted saw blades adjacent the infeed end of the machine, splitting knives mounted directly after the sawing means and defining compartments each adapted to accommodate a lath, and pressure means above each compartment for applying to the laths a pressure directed against the feed table. Planing means are arranged for working, under the action of said pressure, first the lower side and then the upper side of each lath.

Abstract: A device for a woodworking machine (13) adapted at a number of consecutive working stations (14) for processing workpieces which are fed through the machine. The required working of the workpieces can be effected with at least one working station out of operation. The working stations are separated from each other by partitions (20) which extend between external walls (11), a roof (12) and a base and which are closely associated with the machine on either side of the working stations (14) and, like the external walls and the roof, are sound-proof. The tool or tools at each working station can be driven independently of the tools at the other working stations, and each compartment (22) defined by the partitions has a door (21) in the external wall (11). The path of travel of the workpieces through the machine is laterally limited by vertical walls and at the working stations the walls can be provided with covers for forming tunnel portions at these locations.

Abstract: The disclosure relates to a loading apparatus comprising an outer boom and an extension boom (telescopic boom), wherein the C-shaped bight of the hydraulic line, which bight extends in a rearward direction longitudinally of the outer boom and the telescopic boom, is housed in its entirety in a space defined by the walls of the telescopic boom and the outer boom and so arranged that, in all positions of the C-bight at the movements of the bight during extension and retraction of the telescopic boom, the opposite parts of the loop in the area of transition to the C-bight are defined by two relatively fixed walls situated between adjoining surfaces of the telescopic boom and the outer boom.

Abstract: A safety brake for a power saw comprises mainly a brake element arranged to stop the cutter chain when actuated by an actuating member acted upon by a control handle arranged to be automatically operated when the saw operator is beginning to lose control over the saw, whereby the saw will begin to swing upwards against the operator. The actuating member being arranged to form an angle against said control handle and being formed as an oblong flat structure guided to be movable between an inactive position, occupied when the saw operates normally and to an active position for effecting a brake effect on the cutter chain when the saw begins to move uncontrollable. A spring being arranged to retain the actuating member in inactive position by urging it in engagement with a latch, whereas same spring is adapted to effect a positive movement of the actuating member to its active position when it is unlatched by the manual influence from the control handle.

Abstract: An arrangement in a hydraulically operated crane of the type having a supporting crane section and a movable crane arm system supported thereby and comprising support and guide means, telescopically extendable boom means including a first boom movably supported and guided by the support and guide means and a second boom supported by and telescopically movable in relation to the first boom; and drive means for moving the first boom in relation to the support and guide means and for moving the second boom in relation to the first boom; the drive means comprising an elongated flexible drive transmission means fixed to the support and guide means and extending into the first hollow boom through one end thereof and fixed to the second boom, the flexible transmission means being arranged such that a movement of the first boom in relation to the support and guide means will be transmitted by the flexible transmission means to the second boom for moving the latter in relation to the first boom a distance equal to the

Abstract: A control mechanism for a carburetor having a throttle valve and a choke valve each of which valves has an idling position, a cold-starting position and a full-speed position. The throttle valve is spring-biased towards its idling position and the choke valve is spring-biased towards it full-speed position. Control levers are associated with the respective valves whereby when the choke valve is moved from its idling position towards it full-speed position, a lever member associated with the choke valve engages another lever member associated with the throttle valve and the interengaging lever members hold both valves in their cold-starting position in opposition to the biasing springs.
