Abstract: A machine particularly suited for the range or bunk feeding of animal foodstuffs in stacks, large bales, or groups of smaller bales is designed to disintegrate the mass of material on the move and to discharge the disintegrated material in a continuous stream along the ground or into the feed bunk. A vertically swingable lift on the machine picks up the mass and swings it into a raised position wherein the mass is tightly clamped against a deactivated bank of shredding rolls and is maintained protectively cradled in such position for transport to a feeding site. Actuation of the shredding rolls and continued swinging of the lift forces the mass into the rolls to completely disintegrate the mass while the machine is advanced. The bank of shredding rolls is inclined away from the lift such as to facilitate disintegration and discharge of even the last remnant of the mass and to enhance the cradling action provided for the mass during transport and disintegration.

Abstract: Resonant vibration is employed for imparting oscillations to a stressed wire, cable or metallic strip for the purpose of measuring its tension or for setting the vibrated member at a desired tension. A U-shaped magnetic resonator has an air gap to receive a stressed wire or cable and to impart vibrations thereto, the air gap being of such a width as to permit the received element to vibrate freely at its resonant frequency. The tension of the stressed element can be measured by varying the frequency of the resonator and noting when the condition of resonance exists or the tension of the element may be set by varying its tension while subjected to a steady predetermined pulsating magnetic flux field until the condition of resonance is noted. Either operation is performed in the absence of current flow through the stressed element.
