  • Patent number: 11457623
    Abstract: A rodent kill trap in some embodiments includes at least a handle, first and second legs that are at least one of fixedly coupled with or integral with the handle, first and second parallel crossmembers coupled with and extending between the first and second legs, a trigger rotatably coupled with the first crossmember, the trigger including at least a length of the trigger extending away from the first crossmember, a hammer rotatably coupled with the second crossmember, and a sear as part of the trigger configured for being braced against the hammer in a cocked position in which the hammer is rotated about the second crossmember in opposition to a bias mechanism and wherein if the length of the trigger member is engaged by a rodent the sear is configured to be dislodged from the hammer thereby releasing the hammer to rotate in an arc to strike the rodent.

  • Patent number: 6527216
    Abstract: A multi-spindle fiber pay-out apparatus is provided that allows for fiber tension control. A frame supports a plurality of spools of fiber, with each spool of fiber being mounted on a spindle. The spindle is in rotational supporting relation to the spool of fiber and is operatively engaged with a magnetic particle brake, which is itself in control communication with an electronic controller. A fiber take-up system is mounted upon the frame in cooperative relation to the spool of fiber and is arranged so as to compensate for changes in the fiber-pay-out rate from the spool of fiber that are caused by activation/deactivation of the magnetic particle brake. A load cell transducer is mounted on the frame adjacent to the fiber take-up system.
