Abstract: A free wheel lock cylinder includes a main rotor having a plurality of slits communicating with a key hole and a recessed portion communicating with both the slits and the key hole. Tumblers, having positioning notched portions formed on upper edge portions thereof, are slidably received in the slits of the main rotor. An engagement bar, having an underside engageable with the positioning notched portions of the tumblers, is received in the recessed portion of the main rotor and is biased toward the tumblers. A rear rotor is engageable with the main rotor through an interlocking device that is movable in response to operation of the engagement bar. When a proper key is inserted in the key hole of the main rotor, the engagement bar engages aligned positioning notched portions of the tumblers. The main rotor engages the rear rotor through the interlocking device moving in response to the operation of the engagement bar so that the rear rotor turns in response to rotation of the main rotor.

Abstract: In an impact rolling apparatus the axes of roller heads are arranged substantially perpendicularly relative to the longitudinal axis of the workpiece. Accordingly, a displacing of the material at the workpiece proceeds predominantly tangentially perpendicularly to the longitudinal axis of the workpiece, caused by the impact effect of the impact rollers mounted at the roller heads. By this arrangement of the roller heads impact rolling operations can be performed close to a shoulder of the workpiece and marked steps thus maintaining the advantages over the known impact rolling method at which the displacement of the material proceeds predominantly in the direction of the longitudinal axis of the workpiece.

The end face of the platen at its head end is for this purpose of a larger dimension than the active supporting face and has a cutting edge which peripherally surrounds the active supporting face, in the manner of a collar.

Abstract: A compost aerator and monitor which has a cylindrical helical screw, preferably with a sharpened first end. The diameter of the cylindrical helix and the tightness of the windings are selected so as, when the screw is inserted into a compost pile, to create a core of compost material that is sufficiently large to be cohesive and representative but not so large that the weight of the core will cause the core to fall from the screw when such screw is withdrawn from the compost pile. Attached to the second end of the screw is a handle with sufficient leverage to enable the screw to be turned rapidly and, consequently, rapidly introduced into a compost pile and to preclude the screw from rotating as the screw is withdrawn from the pile, thereby retaining the core of compost material. Optionally, either a traditional brace or a traditional power drill can replace the simple handle; and a shaft can be inserted between the screw and the handle or the brace.

Abstract: The present invention relates to a double-acting type dynamic back clearance relief driving system having two sets of worm shafts coupled with a worm gear, one worm shaft set acting as a prime mover worm shaft and the other acting as a displacement control worm shaft. When the system is driving, one of the worm shaft sets is applied with faster rotary driving motion and always applies forces on the worm gear set. Another worm shaft set is a displacement control worm shaft coupled also with the worm gear set, or an individual worm gear set of the same pitch or different pitch to be locked upon the same shaft. The acting force to be applied constantly on the gear by the force applying worm shaft always causes the displacement control worm shaft to stress the worm gear reversely, and since the worm shaft is irreversibly driven, there is no clearance between the worm gear and the two worm shafts.

Abstract: A motion translation machine for converting reciprocating movement to rotational movement includes a frame that has drive pulleys, a drive belt connected to the drive pulleys, at least two perimeter pulleys and a perimeter belt which is supported by the drive pulleys and the perimeter pulleys. At least one drive pulley and both perimeter pulleys are restricted to a single direction of rotation. A reciprocating spindle is attached to the frame and includes a contact pulley which engages with a portion of the perimeter belt. Movement of the spindle causes a displacement of the belt, which, in turn, moves about the frame and drive and perimeter pulleys. Rotational restriction of the pulleys causes the perimeter belt to rotate in a single direction. Each cycle of reciprocation causes both drive pulleys to rotate in the same direction. The reciprocating spindle may be driven by human power or pressurized fluid, including internal combustion engines, and pneumatic and hydraulic cylinders.

Abstract: A CNC automatic lathe has at least one carriage system having an X, a Y, and a Z axis that carries a tool revolver designed as a so-called disk revolver for working with lathe tools and rotary machining tools. In order to reduce as much as possible the distance between a defined cutting plane for the turning process and the carriage system, the Y axis forms with the normal to the cutting plane a relatively small acute angle (beta), so that when the tool revolver is rotated in a controlled manner around its axis, a rotatively driven machining tool mounted on the revolver and located in its working position is swivelled with its axis of rotation through an acute angle out of the cutting plane in the direction of the carriage system. The machining area of the machining tool thus described a movement with a component that extends in the minus direction of the Y axis.
