Abstract: A cutting device for trimming grass and removing soil and debris from around a sprinkler head. The device includes a shaft with a handle mounted at one end to permit the user to push down and turn the device at the same time. A tubular cutting member is mounted at the other end in combination with a foot stand for enabling the user to initially push the cutting member into the ground by standing thereon. A pair of projecting blades extend from the inner surface of the tubular member and are limited in length to permit passage of the sprinkler head therebetween. These blades are also slightly pitched to develop a digging action upon rotation of the device in the ground around the sprinkler head and attached pipe. After the device is inserted into the ground and appropriately rotated, it is withdrawn with the enclosed grass, soil and debris.

Abstract: An osteotome includes an arcuate cutting blade portion and a planar cutting blade portion integrally secured thereto. The arcuate portion is defined from a locus of a perfect circle and is axially elongated relative to the planar blade so as to permit the arcuate blade to be reained within an initially cut portion of a bone while the entire osteotome is rotated to a new, second position in order to perform a second cutting of the bone. The two cuttings of the bone serve to remove a section of the original bone, and in this manner, when the bone sections are repositioned relative to one another, the same will be precisely aligned so as to correct the original bone deformity.

Abstract: A frankfurter coring apparatus for coring the center out of a frankfurter is provided with a handle connected to an annular cutting blade and to a straight edge cutting blade. A pair of frankfurter guides guide a frankfurter to the annular cutting blade centered thereon, while the straight edge cutting blade cuts an incision through the frankfurter to the annular cutting blade. The frankfurter core and cored frankfurter are guided on both sides of the blades.

Abstract: Apples which have been oriented, peeled and cored on the machine shown in U.S. Patent 3,586,081 are further processed to remove the fibrous carpel tissue providing the seed cell in the apple. Following removal of the seed cell, the apples may be discharged whole or passed through a slicing device to cut the apples into a plurality of segments.
