摘要： A cutting link for a saw chain useful in heavy workload operations includes spaced-apart longitudinally-extending planar side portions adapted to straddle a guide bar support and a cutting element mounted on one of the side portions and extending toward the other side portion, the side portions being connectable to other links in the chain. A cross piece interconnects the side portions forwardly of the cutting element. The cross piece forms with the side portions a continuous U-shaped zone which defines a depth gauge to determine the depth of cut of the cutting element. A depending nose tab integral with the cross-piece serves to close off a portion of the forward open channel between the planar side portions to minimize accumulation and packing of sawdust under the U-shaped zone.

摘要： A locking assembly used to deny access to a nut or to a bolt head to prevent theft of an article that is bolted to a body such as a vehicle. The locking assembly includes a retainer through which the bolt passes and that partially surrounds the nut or bolt head that secures the retainer to the body. The retainer includes a groove that extends circumferentially around it. The locking assembly also includes a housing that fits over the retainer and that is selectively engaged to the retainer by a ball bearing that is pushed into the groove on the retainer when a key turns the shaft of a lock which turns a cam that pushes the ball bearing into the groove. The locking assembly has an exceptionally low profile, made possible by positioning the lock perpendicular to the axis of the bolt. Further strength is imparted to the locking assembly by the fact that the retainer is almost as deep in the axial direction as the housing, and the strength of the retainer reinforces the housing.
