Abstract: An apparatus and method for automatically swinging a center pivot, towed implement from one side to the other side of a farm machine. The apparatus includes a Global Positioning System for locating the farm machine and sensors and remote controls for various functions of the machine to check and change the status of each machine function. An on-board computer uses the sensors and the GPS and a previously installed program to automatically determine what portion of the field has been worked and to direct the farm machine to swing the implement from one side to the other as required.

Abstract: Disclosed is an apparatus and method for delivering power utilizing a multiplane power via matrix wherein the vias are each interconnected on each of the planes through which they pass such that a current flowing along any particular via, or via group, is free to either continue along its current path, or to move across any of the planes as a function of least resistance. The invention provides a system of vias for transferring power from any particular first plane to any desired second plane.

Abstract: An air jet assembly supported over a polishing pad provides for raising flattened fibers pressed down by the polishing of semiconductor wafers and for blowing spent polishing materials and by-products off the pad. The polishing pad is supported on a rotatable platen and includes fibers which normally extend substantially perpendicular to an upper surface of the polishing pad. The fibers are coated with chemicals for polishing the surface of semiconductor wafers during the chip fabrication process. The fibers of the polishing pad tend to flatten down against the platen during the polishing process and spent polishing materials and by-products become embedded in the fibers of the pad. The air jet assembly is supported over the pad and includes an elongated pipe having an inlet port and a plurality of output ports. The inlet port is coupled to an air supply which forces air into the pipe and out through the outlet ports.

Abstract: An apparatus and method for oscillating the dampening form roller in a lithographic printing press to provide a substantially uniform application of dampening fluid on the printing plate. The form roller is comprised of a rotatable shaft and a cylindrical roller concentrically disposed on the shaft. A double-ribbed barrel cam is coupled to the roller so as to be rotatable therewith and first and second cylindrical cam followers are disposed a predetermined distance apart on the shaft for receiving the cam therebetween so that a first major surface of the cam is in contact with the first cam follower and a second major surface of the cam is in contact with the second cam follower. The "rise and fall" of the cam as the cam rotates relative to the cam followers imparts an oscillating motion to the roller. The rate of oscillation is substantially the same as the rate of rotation of the cam relative to the cam followers.

Abstract: A drawn conjugate yarn of an elastomer and a non-elastomer is wound on a bobbin with a crushable surface. Yarn can be knit from the resulting package successfully after long storage periods.
