Abstract: The invention provides a clamping apparatus, particularly for receiving and clampingly retaining electrode body blanks having prismatic or circular cross section for erosive machining devices. A clamping block has at one of its surfaces an essentially centrally arranged clamping chamber to receive the electrode. Two adjacent walls of the clamping chamber are provided with clamping screws protruding into the clamping chamber.

Abstract: A wheel assembly adaptable for use with a motor vehicle, a light aircraft, and the like, or in a pulley system or gear train. The wheel assembly comprises an axle or spindle-retained hub member, and a removable wheel member that is releasably connected by unique snap/lock pins.
