Abstract: An electric device, for example a shredder, comprises a cutter mounted on a base and driven by an electric motor, the cutter being concealed by a removable feed chute. A plug connector of a cord set is movably secured to the feed chute, and is moved towards and away from the feed chute to plug it with and unplug it from a plug connector of the motor. The plugging together of the plug connectors prevents removal of the feed chute; it being necessary to unplug the connectors to disconnect electrical supply to the motor by moving the cord set plug connector outwardly of the base before the feed chute can be removed to expose the cutter. Preferably, the cord set has incompatible plug connectors at each end to prevent a normal extension cord being plugged to said motor plug connector when said feed chute is removed.

Abstract: The invention is a dehorner for removing horns from the skulls of cattle or the like comprising a frame with a cutting side defining a plane and an operator side and having a fixed blade and a reciprocating blade which is projected toward the fixed blade during dehorning, both blades containing base portions which are contained within the plane of the frame and riser portions which extend outward from the plane of the frame on the cutting side so that the blades cut behind the base of the horn into the softer portion of the skull and remove all of the horn from the skull of the cattle.

Abstract: An apparatus and method for soft recovery of a projectile is disclosed. A formable element is placed in the path of the projectile, whereby the projectile becomes embedded in the element upon impact therewith. Gravitational or mechanical forces are applied to the combined projectile and deformable element to decelerate the same thereby making recovery possible.
