Abstract: A device for separating and closing a split mold that comprises a base, a stationary platen, and a movable platen extending upward from the base and oriented to oppose each other, electromagnets, a hydraulic cylinder, and a control panel. The movable platen is capable of movement toward and away from the stationary platen by the hydraulic cylinder. The stationary platen has the electromagnets mounted thereon and the movable platen has the electromagnets mounted thereon. In the use of the device, the mold is positioned upon the base such that the first half is positioned against the stationary platen. The movable platen is moved against the second half and the electromagnets are activated. The movable platen is then moved away from the stationary platen, and the mold halves are held against their respective platens by the attractive forces of the electromagnets. Mold halves are thus separated by the movement of the platen away from the stationary platen in activation of the electromagnets.

Abstract: An ice fishing apparatus and signaling device (10) includes a base (12), a fishing line (22) depending from the base (12) and having a hook (36) on its end, a trigger (38), a transmitter (60), and a receiver (62). An arm (42) is spring mounted to the base (12) such that it is movable from a trigger held horizontal position to a vertical position. The arm (42) moves from the horizontal position to the vertical upon a fish strike, thus engaging a switch (64) that completes a circuit that produces a radio signal from the transmitter (60) to the receiver (62).
