Title: Delayed fuse for rotation stabilised projectiles - has connected train of discs around fuse axis
Inventor: FIEBRICH JOACHIM
IPC: F42C15/20
Filed: 1973-06-26
Abstract: The delaying unit for the fuse is a train of discs each of which has a central shaft and arcuate, concentric slot. Each disc has a pin which engages with the slot of the neighbouring disc. Each driven disc starts to rotate after its driving disc has completed its movement. This movement is started when the driving pin has arrived at the end of the driven slot disc. Hence the last disc begins to rotate only after all connected discs have completed their movements. After the discs have completed their movements the firing pin travel path is free to initiate the detonator. This delay mechanism is of extremely flat construction and two or three mechanisms can be stacked for prolonging the delay time.

Title: Tree-trunk root end width trimmer - with flat end plate with radial cutouts in inner periphery between rotor blades
Inventor: JONSSON KARL-ERIK
IPC: B27L1/05
Filed: 1973-08-21
Abstract: The hollow rotor, with cutters inside, is for reducing the width of the thick root end of tree trunks or fallen trees so that they can be passed through a bark stripper. The flat round plate, with radial cut-outs, is at the entry end, and there is an encompassing column with one or more blades pointing radially inwards in front of the rotor entry end, extending to a peripheral line running through the blade radial outer parts. Clinging bark strips, splinters and other pieces of wood collected between trunk and rotor opening are shaved off as the rotor turns round, in conjunction with the edges of the cut-outs. This saves the rotor from being hindered in its main function of dealing with root ends.

Title: Automatic coupling drive - has driving disc on which hollow planet wheels are mounted which are partly filled with liquid
Inventor: BOEHMER ALFONS
IPC: F16H47/00
Filed: 1974-06-07
Abstract: The drive consists of a disc which is mounted on a driving shaft. Two or more planet wheels are mounted equally spaced on a pitch circle diameter on the driving disc. The planet wheels consist of hollow discs (4) with internal radial vanes and pinions (41) which are mounted concentrically to the hollow discs. The pinions engage with an internal gear rim (51) on a disc which is co-axial with the driving disc. The hollow discs are partly filled with a fluid such as oil. The drive shaft is mounted directly to the driving motor. During start up, the planet wheels move over a circular path while being rotated by the pinions. Centrifugal force together with gravity will cause the fluid to accumulate at one side in the hollow discs. This will cause a reaction force on the output disc. When the speed increases and the centrifugal force makes the position of the hollow discs more rigid, the output wheel will be rotated with the input wheel.
