Abstract: Safety device for quick-fit attachments comprising two parts (1) and (2), of which one (1) is borne by the arm of the digger while the other (2) is secured to the tool (for example a dipper), said first part having a cradle (3) formed by a pair of hooks, able to grasp hold of a shaft (4) belonging to the second part in order to raise the tool and allow the first part to pivot so that the two parts can be pressed against one another to allow for locking, characterized in that each part of the attachment has a member (7) able to collaborate with a member (8) of the other part if the weight of the tool being picked up does not exceed the capacity of the digger, collaboration being impossible when such is not the case, so that the first part is unable to be pressed against the second and locking is prevented.

Abstract: Tool designed to be fixed at the end of the arm of a shovel. The tool includes a curvilinear blade formed by a portion of a straight cylindrical surface whose generating lines extend parallel to an axis of rotation of the tool on the arm. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.

Abstract: Corn sterilizing machine of the type using rotary blades. The machine uses a castrating head in the form of a case enclosing a rotary blade. The front surface of the case has a slot allowing for the introduction of the panicle to be cut. Each one of the vertical edges of the slot has a pivotable shutter having two upper and lower ramps, respectively.

Abstract: This invention relates to a method and apparatus for the trapping of animals in a humane manner whereby the animal is not injured during the trapping process, nor is it subject to injury following trapping. The trap comprises an elongate chamber having a top, bottom and two sides, and end covers which are in the form of slidable doors. The floor of the chamber includes a pair of hinged panels which are in a slightly raised position when the trap is set. A link system projects upwardly through an opening in the top of the chamber and is attachable to the trap's triggering mechanism. The trap is generally set by lockingly engaging the end covers in a raised position and engaging the link system with the trigger mechanism. When an animal enters the trap and steps upon the raised floor panels, the triggering mechanism is actuated which unlocks the end panels from their raised position and permits them to drop to a closed position, thereby safely entrapping the animal within the chamber.
