Abstract: A fiber bundle cutting device is disclosed which includes an elastic roller; a cutting roller having a plurality of thin plate-like cutter blades extending radially therefrom, the cutter roller being disposed in parallel relation with the elastic roller in such a manner that the cutter blades can be slightly pressed against a surface of the elastic roller; a plurality of push-out members each movably mounted between a respective pair of the cutter blades and disposed adjacent to one another; and ring members respectively holding the opposite ends of each of the push-out members to maintain the push-out members in a generally cylindrical configuration; the ring members and the push-out members held by the ring members being movable to an eccentric position relative to the cutter roller so as to progressively move from the proximal to the distal edge of the cutting blades during the operation of the cutting device to discharge the cut pieces of a fiber bundle.

Abstract: A combustion gas powered fastener driving tool includes inlet and outlet openings through which the combustion gases are discharged from a combustion chamber. These openings are located above the uppermost driving position (top dead center) of a slidable piston, so that an air and fuel mixture is fully trapped in the combustion chamber until after it is combusted. Since an outflow of the unburnt air and fuel mixture is completely prevented, the rate of fuel consumption of the fastener driving tool is high and there is no danger of accidental explosion of unburned fuel even when the fastener driving tool is used in a badly ventilated working place or site. An electric fan for forcing fresh air into the combustion chamber is disposed outside the cylinder and isolated from high temperatures. The fan is durable in structure and reliable in operation.

Abstract: An apparatus with two limit positions and generating a reciprocating motion, comprises a first moving part (4a, 4b) and a second moving part (16a, 16b) between which parts (4a, 4b; 16a, 16b) a pressurized drive medium (38a, 38b) such as compressed air, is disposed to simultaneously displace the moving parts (4a, 4b; 16a, 16b) in mutually opposite directions. At least the first moving part (4a, 4b) is actuated, by a constantly present force, for example by the pressure of the driving media (38a, 38b) applied on at least one surface of the first moving part (4a, 4b), in the forward direction under tensioning of an associated force accumulator (20a), for example a spring.

Abstract: There is disclosed a surgical instrument for implanting in bodily tissue, wound staples each comprising two legs and a crown connecting the legs. The staples are moved in succession out of a magazine onto an anvil, to be deformed thereon by means of a driver. The driver is lowered from a position of rest towards the staple on the anvil, and is further moved to close the staple on the anvil by bending the staple theraround, and to insert the legs of the staple into the bodily tissue. For problem-free and symmmetrical deformation of the staple, a hold-down device is lowered onto the anvil and upon deformation of the staple thereon presses the crown of the staple onto the anvil and so prevents the staple from moving laterally during its deformation.
