Abstract: A drive system includes a drive housing and one or more drivetrain cartridges. The one or more drivetrain cartridges enables better manufacturability by allowing drivetrain components to be installed together outside the housing and then installed as a unit together into the housing. Serviceability is improved by allowing one or more of the drivetrain cartridges to be removed individually from the housing for maintenance or repair. The housing may include mounting surfaces to securely engage the one or more drivetrain cartridges to the housing to prevent play. The housing may include a bottom or side panel with installation mounts to fasten the drivetrain cartridge or cartridges securely to the bottom or side panel of the housing.

Abstract: A spreading apparatus for spreading material onto a target area is disclosed. The spreading apparatus includes a container for the material, a discharge unit which discharges the material, a deflector door disposed on a discharge port of the discharge unit, a positioning device which positions the deflector door and a controller configured to control the deflector door so that the deflector door is positioned between a first closed position and a second open position. The material is substantially prevented from exiting through the discharge port when the deflector door is in the first position. The deflector door may further be positioned at a position between the first closed position and second open position to control a distance of the material discharged from the discharge port.

Abstract: A system for osteosynthesis of the spine. The system includes at least two pedicular screws and a linking plate for linking the screws together in an essentially rigid manner. Each screw has a bone anchoring threaded part, a non-circular section head, and a threaded end shank adapted to cooperate with a nut. The plate has at least one opening adapted to have the threaded end shank of a screw passed through it and be trapped between the screw head and the nut. A locking member is also provided for preventing relative angular movement between the heads of the screws and the linking plate. The locking member is adapted to be inserted between the plate and the screw head and includes a bore through which the threaded end shank of the screw passes, and further includes a first locking cooperation of shapes with the screw head and a second cooperation of shapes with the plate.
