Abstract: A hydraulically operated drive system for mini-loaders and like machines is disclosed. The system incorporates hydraulically operated wheels or sprocket/track arrangements as well as auxiliary functional mechanisms. Tandem hydraulic pumps are used, each one thereof being connected to a multiple spool series valve, providing two separated hydraulic circuits, each of which has a separate relief valve. Each multiple spool series valve controls a wheel motor and a loader/lift or like function. Each multiple spool series valve includes a single-acting spool connected to a common spool valve to provide auxiliary power control.

Abstract: A handle housing that is modular and easily assembled and disassembled for maintenance and cleaning. The handle housing has an integrally-formed orientation shape (e.g. S-shape) to keep it from tipping onto the flossing tip. The handle housing also includes the rocker arm, cam drive (together the drive train), motor, power supply and bobbin for full functionality, with linear, reciprocating motion created by the drive train for effective cleaning.

Abstract: A flosser tip holding cartridge including one or two internal storage rails having a base for supporting the rails upright on a support surface. A housing surrounding and protecting the storage rails and a slot in the front portion of the housing for accessing each rail. A tip removal slot on the top side for facilitating the removal of a flossing tip from the flossing device. Each rail includes a longitudinally-oriented recess having side walls that define a shape that closely receives individual flosser tips for storage and access.

Abstract: This invention relates to an automatic release mechanism for a cultivator which provides good resistance to release of the shank holder and which upon release causes the shank holder to rise to a good height to clear obstacles encountered during operation of the cultivator. The shank holder is mounted so as to pivot about an axis and is retained in the working position by a pair of springs under tension, the forward end of the springs being mounted in front of and beneath the position of the pivot axis of the shank holder, and the moment arm of the springs is such that, as the shank holder pivots, the moment arm decreases resulting in the tangential force applied by the springs to the ground engaging tool about the pivot axis remaining substantially constant during pivoting of the shank holder to clear an obstacle.
