Abstract: A speaker assembly having a removable grill. The grill includes a perforated portion circumscribed by a flange. The flange has one or magnets disposed around an outer periphery of the flange. The speaker body has corresponding slugs disposed so as to align with the magnets of the grill upon assembly. The magnetic bond formed between the slugs and magnets keeps the grill attached to the speaker body during operation of the speaker assembly.

Abstract: A CNC machine for automatically re-indexing and machining multiple faces of a workpiece includes a traditional three-axis CNC machine and a gripper tool. A bar stock defining a first and at least a second workpiece is loaded within a first and a second vice on the table such that the first workpiece is disposed within the first vice and at least a portion of the second workpiece is disposed within the first and the second workpiece. The CNC machine machines the first face of the workpiece within the first vice. Next, the CNC machine grasps the first workpiece using the gripper tool removably disposed within the spindle. The first workpiece is re-indexed and is loaded into a third vice disposed on the table and the next face of the first workpiece is machined. A support rack is preferably used to support a portion of the bar stock overhanging the table.

Abstract: A tree delimber including a frame having a track for guidably supporting a carriage having a boom and grapple assembly thereon, the carriage being driven for movement on the track between the ends of the frame with a tree delimbing assembly at one end of the frame having an articulated chain with blades and an articulated arm with blades which completely surround the peripheral surface of a tree trunk positioned in the tree delimbing assembly by the boom and grapple assembly. The carriage is provided with jaws for gripping the butt end of a tree trunk so that when the carriage is driven along the track, the tree trunk is pulled along the frame through the tree delimber assembly permitting the blades to remove the limbs from the peripheral surface of the tree trunk.
