Title: Planetary gear system with elastically deformed planet wheels and multi-stage control of the speed of revolution
Inventor: STEUER WILLI DIPL ING
IPC: F16H15/54
Filed: 1986-01-20
Abstract: The ring gear and sun gear consist in each case of a pair of conical discs (1, 2) and (3, 4) which can be displaced axially with respect to one another, with annular springs (33) and (34) which are arranged respectively between them and are held between the legs of bars which are connected tangentially to the discs at the side in grooves and guided radially. In this arrangement, the bevels (F1) and (F2) of the ring gear discs converge radially outwards and the bevels (F3) and (F4) of the sun gear discs converge radially inwards. Tooth-type chain segments (35) and (36) which are arranged on the circumference, can be displaced on one side with respect to the annular springs and discs and are in toothed engagement with the planet wheel (6) are supported in the radial direction against the annular springs (33) and (34). The planet gears are supported in a radially displaceable support (10) on the plant carrier (5). When the speed of revolution changes, the conical discs (1, 2) and (3, 4) are displaced axially with respect to one another in such a way that the distances between the discs on the ring gear and sun gear change inversely proportionally with respect to one another. In this process, the diameters of the annular springs (33) and (34) and those of the crown gears (35) and (36) which guide the planet gears radially between them change. The gear wheels turn synchronously in the gear-shifting process. The pitch of the chain teeth and the displacement device of the tooth-type chain segments are matched to one another in such a way that a pitch jump does not occur. <IMAGE>

Title: Drilled hole protection forceps
Inventor: HEINZE WERNER
IPC: A61B17/17
Filed: 1986-05-22
Abstract: The drilled hole protection forceps, for which patent protection is claimed, permits reliable gripping of the bone parts by parallel guidance of the carriage and fixation with a fixing screw. This double guidance of the drill prevents it from tilting and permits accurate drilling through bone parts. Movement of the carriage takes place by actuation of the upper part of the forceps. This ensures immobilisation of the lower part of the forceps. Traumatisation of the regions lying under the base of the lower part of the forceps is thereby avoided.
