Abstract: A wear assembly includes an adapter with a nose, a wear member with a socket to receive the nose, and a lock to secure the wear member to the adapter. The nose and socket include complementary rails and grooves that vertically diverge as they extend from the front of the nose. The lock can have a tapered construction.

Abstract: A wear assembly for securing a wear member to excavating equipment that includes a base having a nose and a wear member having a socket. The nose and socket are each provided with one or more complementary stabilizing surfaces in central portions thereof.

Abstract: A wear assembly for excavating equipment that includes a base, a wear part and an improved locking arrangement that provides improved stability, strength, durability, safety and ease of use. The locking arrangement includes a hammerless lock that is pivotally moved between hold and release positions, wherein the fulcrum is set forward of the bearing surface engaging the wear part. The lock can be manipulated by a threaded member or pry tool. The lock further includes bearing surfaces that enhance stability and reduce wear.

Abstract: A tip for use on an earth working roll for mining, construction and public works machines such as crushers, surface miners, milling machines and the like includes a working end provided with side relief to reduce drag and wearing, require less power to drive the rolls, and lengthen the usable life of the tip. The working end can also have a generally flat front surface to improve the yield in a crushing or other similar operation. The tip includes a base and a wear cap releasably secured together by a retainer.

Abstract: A locking assembly for retaining a wear member to excavating equipment has a locking element that is received into an opening in the assembly and is movable about a pivot axis in the opening between a hold position and a release position. The locking element has an outer edge that is generally opposite the pivot axis that opposes a base surface of the opening when the locking element is in the hold position. The outer edge is configured to pull away from the base surface when the locking element is rotated from the hold position toward the release position.

Abstract: A wear assembly provided with a tapered opening and a complementary tapered lock wherein the lock can be pried into and from the opening to thereby eliminate the need for hammering. The lock is formed with a body and a latch that is movable between a hold position where the latch is engageable with a stop in the opening to releaseably retain the lock in the opening and a release position where the latch disengages the stop.

Abstract: A wear assembly for excavating equipment which includes a wear member and a base each with upper and lower stabilizing surfaces that are offset and at overlapping depths to reduce the overall depth of the assembly while maintaining high strength and a stable coupling. The nose and socket each includes a generally triangular-shaped front stabilizing end to provide a highly stable front connection between the nose and wear member for both vertical and side loading. The lock is movable between hold and release positions to accommodate replacing of the wear member when needed, and secured to the wear member for shipping and storage purposes.

Abstract: A locking assembly has two members which are moveable into coupling engagement with one another. The two members have lock engaging walls, and one of the members has an opening between the lock engaging walls for receiving a lock. The lock comprises a lock body and a retainer. The lock body has a channel for receiving a portion of the retainer. An end of the retainer extends underneath a retainer engaging wall, thus resisting movement of the lock out of the opening.

Abstract: A wear assembly including an adapter, a wear member, and a lock to secure the wear member to the adapter, wherein the adapter and wear member include at least one rail and corresponding groove along the nose and socket connection that are oriented at the same general inclination as one of the converging walls of the nose.

Abstract: An extremely secure method for keying source contents to a source storage medium provided to prevent use of unauthorized copies at minimal cost. The host processor combines a unique, immutable and verifiable physical attribute of a hard disk drive, i.e., the drive's defect list, with the content to be secured to write a corresponding fingerprinted encrypted content on a source medium. When a local processor wants to use the sanctioned source content, the fingerprinted content is read from a local storage medium. The local processor then decrypts and separates the defect list out of the source content and reads the local storage medium defect list. If the decrypted defect list matches the local storage medium defect list, then the local processor recognizes the local sanctioned medium and continues processing the source contents. Otherwise, a non-matching defect list indicates an unauthorized copy from the source to the local storage medium.

Abstract: A synchronous calibration test circuit in accordance with the principles of this invention that uses a bandgap reference voltage of a PRML chip and a write clock synthesizer to generate an output reference calibration signal comprising a programmable frequency and whose amplitude is invariant with environmental conditions. This reference signal is injected at the input of a signal path of the PRML chip and measured after the PRML's A/D converter using the synchronous test calibration circuit of this invention. Since the programmable frequency reference signal is insensitive to voltage supply fluctuations as well as temperature and process variations this reference signal can be used to measure and characterize changes in the transfer function of the analog signal path of the PRML chip.
