Abstract: In one aspect of a livestock device, the livestock device may be configured with two opposed and corresponding door frames. A neck bar may be engaged with each door frame via an upper extension arm and a lower extension arm. The door frames may be selectively moved between an open and closed position with respect to one another. The neck bars may be selectively moved between a retracted and extended position with respect to the door frames. The livestock device may be configured to secure the position of, restrain, and/or properly orient an animal, and/or to secure the position of, restrain, and/or properly orient a portion of an animal (e.g., its head, neck, etc.) with respect to another portion of the animal.

Abstract: A headgate including pair of upright frame members with a pair of weight members disposed therein which are connected to a pair of stanchions operable to move from an open position to a closed position by pivoting linkages. A release mechanism simultaneously releases the weight members from a first position such that gravity causes the weight members to move from the first position to a second position located at a lower height than the first position upon receiving a signal from a tripping mechanism which automatically detects the presence of an animal, wherein the release of the weight members causes the pair of stanchions to move from an open position, which allows an animal to pass therethrough, to a closed position, which causes the stanchions to close so as to confine the animal.

Abstract: An apparatus for preventing warping of a rotatable base for supporting an object being processed in a Rapid Thermal Processing (RTP) system due to non uniform heating of the base by radiation from the object being processed is disclosed.
