摘要： A milling device comprises two milling bodies one of which is hollow and encloses the other, and a driving unit connected to one of the milling bodies via a shaft nonrotatably connected with the one milling body to cause it to rotate about its own axis in rolling contact with the other milling body. Both milling bodies are universally movable in a surface essentially transverse to the axis of rotation, but are actuated by a return force which increases as the pendulum movement increases. To provide for the return force, the two milling bodies are supported in pendulum fashion, or use is made of resilient means, such as springs.

摘要： A composition consisting of carbon powder, water and a dispersing agent. The particle size of the carbon powder is less than 100 .mu.m, preferably less than 40 .mu.m. The composition is obtained by preparing a mixture of about 1-20% by weight, preferably about 10% by weight, of carbonaceous powder, water and 0.02-4% by weight of dispersing agent. The dispersing agent is selected preferably from polyelectrolytes, such as alkali metal and ammonium salts of polycarboxylic acids, and polyphosphates. These substances possess the property of charging the powder particles of carbon and the impurity particles in a different degree. This different charging is utilized to separate impurity particles from carbon particles, whereupon the purified composition is suitably dehydrated to attain an increased carbon powder concentration of, for instance, 50-80% by weight.

摘要： A belt conveyor with at least one endless belt (1,1') has two tensile force (longitudinal)-absorbing members (3,4,3',4') which extend throughout the entire length of the belt conveyor and which are each connected to a respective edge portion of the belt and project from the plane of that edge portion. The belt conveyor is sealed at a longitudinal edge throughout at least part of its length. One edge portion of the belt overlaps and extends outside the other edge portion of the belt along the sealed part of the length of the belt conveyor, more specifically with its tensile force (longitudinal)-absorbing member (3,3') projecting in the same direction as the tensile force (longitudinal)-absorbing member (4',4) of the other edge portion of the belt. When the belt conveyor has a single belt (1), the two tensile force (longitudinal)-absorbing members (3,4) of the belt project from opposite sides of the belt (1) in the straightened state thereof. When in the case of a two-belt conveyor, each belt has two tensile force (longitudinal)-absorbing members, these may project either from the same side or from opposite sides of the belt in the straightened state thereof.

摘要： Burner for a suspension of fine-grained coal in a liquid, particularly water, which burner operates according to a combination of the rotary burner and toroidal burner principles. The fuel is supplied axially behind a transverse distribution baffle within a conical rotary body. At least the outer rim portion of the inner side of the rotary body forms an angle of 35.degree.-80.degree. with the axis of the burner. At the outer edge of the rotary body there is an annular air supply nozzle for supplying a conically diverging outwardly directed air stream. Outside the air supply nozzle and at a radial distance from it, there is a conical guide baffle (18, 48) which at its outer end may be curved inwardly and which, together with the diverging air stream, serves to produce a positive recirculation of combustion gases, non-combusted coal particles and ash particles in a direction back towards the rotary body in accordance with the toroidal burner principle.

摘要： A wheel-chair has a foldable frame structure (10) which is lockable in the unfolded state and carries wheels (11, 12) and a back (13). In the folded state, all fixed parts are folded up between the wheels of the wheel-chair. The frame structure (10) is box-shaped and has foldable set and bottom members (15, 17) and foldable front and rear wall members (19, 20). These seat, bottom, front and rear wall members are pivotally connected to side wall members (14). The seat and bottom members (15, 17) consist of two parts and are folding upwards and are mechanically interconneted by means of a central wall (18) for common folding movements. The front and rear wall members (19, 20) also consist of two parts and are mechanically interconnected for common folding movements by means of a rod (22) disposed underneath the bottom portion (17). The back (13) is also made of two parts (26, 27) which are pivotally connected to the rear edge of a respective part (15) of the seat member and extend downwardly towards the bottom member (17) such that they can be locked in the unfolded state by means of a locking device (37) provided on the rigid member (22). The front and rear wall members (19, 20) are angled rearwards in all positions of the wheel-chair. The large wheels (11) of the wheel-chair have a driving ring (89) which can be moved between an inner and an outer position and which is fixed on the hub (60) of the wheel by means of leaf springs (90) and which, when the driving ring is moved between said inner and outer positions, passes an unstable position of maximum tension of the leaf springs. Also, the large wheels (11) of the wheel-chair are provided with disc brakes (80) the brake discs of which are connected to the frame structure (10) of the wheel-chair by means of a rotation-inhibiting pin member (87) and by means of a nut and screw thread (81, 83) which, when a brake handle (86) is pivoted, will move the brake disc (80) into frictional engagement with a braking surface (67) on the side face of the hub (60) of the wheel.

摘要： A belt conveyor having a conveyor belt which is flexible in the transverse direction and which, along part of its path of travel, is twisted about it own axis from a lower guide roller (2) to an upper guide roller (3) for forming a tube for the conveyance of goods. The belt (1) runs over the guide rollers in a transversely substantially straightened state. The guide rollers (2, 3), in dependence upon the pitch of the belt (1) in the twisted part thereof, are so inclined relative to the center line of the tube that the two edge portions (6, 7) of the belt in the twisted part thereof engage each other substantially edge to edge. The edge portions (6, 7) of the belt (1) have substantially inextensible reinforcements (8, 9) for taking up longitudinal tensile forces in the belt. The belt is further so stretched and twisted between the guide rollers (2, 3) that the edge portions (6, 7) in the twisted part of the belt engage each other substantially edge to edge and follow helical lines which are contained in a cylinder surface having a smaller diameter than the diameters of the cylinder surfaces in which the helical lines for other longitudinal portions of the belt are contained.
