Abstract: A beadlock to secure a tire to a wheel. The beadlock comprises a first grip element and a second grip element. The first grip element is welded to the outer rim of a wheel. A bead of the tire is positioned over the first grip element. The second grip element has a plurality of rib elements angularly spaced around its periphery. The second grip element is secured to the first grip element such that the ribs grip the bead to hold it in place and secure the tire to the wheel.

Abstract: A counterbalance system for an upward acting door including a first casing and a second casing. Each casing includes a spring element disposed therein operable to store and release potential energy in response to movement of the upward acting door between open and closed positions. The first casing is interlockable with the second casing to accommodate and counterbalance upward acting doors of differing weights.

Abstract: A method and device for nondestructive and noncontact detection of faults in a test piece, or electrically conductive particles in a liquid flow, moving passed the device, using eddy currents. The test piece or flow is exposed to periodic alternating electromagnetic fields. A periodic electrical signal is detected. The receiver coil signal is digitized with an A/D converter stage. A useful signal is produced from the digitized receiver coil signal with a signal processing unit, and the useful signal is evaluated with an evaluation unit for detecting a fault in the test piece or electrically conductive particles. When overdriving of the A/D converter stage by the receiver coil signal is ascertained by monitoring the curve shape of the digitized receiver coil signal, a part of the receiver coil signal truncated by the A/D converter stage is reconstructed using a mathematical approximation in the digitized receiver coil signal.
