摘要： A reduced pressure pneumatic animal stunner with a low-complexity valve and venting system, and method of use thereof, is disclosed. The stunner includes a hollow housing, a stunning rod chamber, a head contact movable within an outer housing nose, a stunning rod, and a catch system employing at least one arcuate catch, a catch retainer, and a catch piston slideable within an opening of a catch cylinder. The catch piston has passageways disposed therein to allow for flow of a pressurized fluid therethrough. One passageway allows fluid to flow to a rearward end of the stunning rod chamber, and another allows fluid to flow to a forward end of the stunning rod chamber. Pressurized fluid may flow from a source through an internal passageway to the front of the stunning rod chamber alongside at least one resilient cushion designed to cushion stop the forward movement of the stunning rod.

摘要： A power skinning knife having a disc shaped blade (12) driven in unidirectional rotary motion with a pair of blade shields (18) on opposite sides of the blade covering most of the blade and exposing only a limited depth arcuate cutting region of the blade between the perimeter of the shield and the cutting edge. The blade is driven by a motor geared to turn first and second toothed pulleys (48, 52) connected by a toothed belt (50). The blade may be circular or lobed and mounted concentrically or offset to provide either a smooth or pulsing cutting action. The tool may also include a wiping element (70) which removes debris from the blade edge before it enters the tool housing and a steeling element (68) which can be actuated by the operator's thumb while the tool is being used to sharpen the blade.
