Abstract: A method and apparatus for reducing power in a computer system having a counter and a phase generator. The method consists of receiving an input clock signal which has a plurality of clock cycles and receiving an enable signal. If the enable signal is active, then the counter performs a divide operation. In addition, a block signal is generated when the enable signal is active to hold the output signal in its present state. The block signal is removed if the divide operation is completed or if the enable signal becomes inactive. When the enable signal is not active, then the output signal generated is equal to and in phase with the input clock signal if the enable signal is not active.

Abstract: An apparatus for selecting a clock source in a microprocessor. The apparatus receives a first clock and a second clock. The apparatus has a clock select unit capable of detecting the first clock and selecting between the first clock and the second clock without an external selection signal indicating which clock is to be selected. If the clock selection unit detects the first clock, then the first clock is selected. Otherwise, if the first clock is not detected, then the second clock is selected. The clock selection unit provides an output clock based on the selection.

Abstract: An agricultural tool bar having a main beam and a pair of tool supporting side wings which fold forwardly from an extended operating position to a folded transport position. The inner ends of the wings are attached to hinges which are pivoted to a carriage mounted for rolling movement along the main beam. Hydraulic cylinders pivot the hinges relative to the carriage as diagonal links cause the carriage to roll along the beam in a manner to fold and unfold the side wings. Additional hydraulic cylinders act to raise the main beam to the transport position wherein the side wings are wholly supported on the main beam which is in turn supported on a wheel assembly having a sturdy axle underlying it.

Abstract: The invention related to an apparatus for lifting, handling, transporting and unrolling large round hay bales. Preferably said apparatus is employed on the bed of a pickup or truck and includes a frame mounted on the pickup bed with a beam pivotally mounted thereon and with arms pivotally mounted on the beam. The arms have bale penetrating members mounted or fixed thereon. First power actuated means operably pivot the beam in an arc about the rear end of the pickup toward and away from the ground. Second, power actuated means for pivoting the arms and penetrating members about the ends of the beam toward each other in such fashion as to squeeze a bale sufficiently to allow the first power means to lift the bale from the ground, and to pivot away from each other to release the bale. The bale penetrating members are mounted on the arms to allow a bale to be unrolled or distributed.

Abstract: The invention relates to an apparatus for lifting, handling, transporting and unrolling large round hay bales. Preferably said apparatus is employed on the bed of a pickup or truck and includes a frame mounted on the pickup bed with a beam pivotally mounted thereon and with arms slidably mounted on the beam. The arms have bale penetrating members rotatably mounted or fixed thereon. First power actuated means operably pivot said beam in an arc about the rear end of the pickup toward and away from the ground. Second power actuated means slide the arms and penetrating members along said beam toward each other in such fashion as to squeeze a bale sufficiently to allow the first power means to lift the bale from the ground, and away from each other to release the bale. The bale penetrating members are rotatably or fixedly mounted on the arms to allow a bale to be unrolled to facilitate feeding the hay of the bale to animals.
