Abstract: A surgical trocar includes a trocar needle with a sharp tip for puncturing and passing through the skin of a patient. A hose barb disposed on a distal end of the trocar needle retains a drain tubing while they are being threaded through a skin puncture. A head formed aft of the tip of the trocar needle has a locking ridge to provide a grip. A tapered section of the trocar needle is disposed aft of the head and has its minimum diameter adjacent to the locking ridge, and its maximum diameter in the direction of the hose barb. Thus, a gradually increasing diameter of the tapered section aft of the head substantially reduces any snagging or tearing of a patient's skin around an associated skin puncture during use.

Abstract: A tree shaker attachment is disclosed which is preferably adapted for mounting on the lift arms of a vehicle, the attachment including relatively movable jaws each having a clamping pad for engaging a tree or the like, a linear motor means operating an actuating cam means against a first elongated ramp on a movable jaw. A pivotable link is interconnected between the actuating cam and a relatively fixed member of the attachment in order to cause linear operation of the motor or jack to shift the movable jaw toward the other jaw, the attachment also including shaker means for vibrating a tree or the like engaged by the clamping pads of the jaws.

Abstract: A mounting assembly for supporting a side-mounted implement such as a mower attachment or the like upon a tractor includes a central mounting beam extending longitudinally beneath the tractor with front and rear saddles connecting the beam with the front housing and rear tractor axle, a support arm assembly interconnecting the implement with a central portion of the beam so that the weight of the implement or reaction forces from the support arm assembly and implement are transferred directly to the front housing and rear axle of the tractor.
