Abstract: An electronic measuring rule wherein the rule tape is formed integrally with a magnetic recording tape imbedded therein along the longitudinal axis of the tape rule. The recording tape which has spaced indicia signals recorded thereon is molded into a recess along the longitudinal center of a vinyl tape so that the vinyl tape covers the outer edges of the magnetic recording tape and the back thereof. A thin protective resin layer covers the recorded side to protect it from abrasions during use. Visible indicia are printed on both sides of the vinyl tape, top and bottom, on each lateral side so that the tape may be "read" visually in the usual manner from either lateral side, both top and bottom.The recording tape portion of the measuring rule is "read" directly by a pick-up head located within the case adjacent the location where the tape exits the enclosing case.

Abstract: This invention comprises a portable impact driven log cone splitter mounted to a power source such as a chain saw power unit. The wood or log splitter is coupled to a chain saw power unit through an appropriate gearing arrangement in one preferred embodiment. The blade is removed from the conventional power saw unit and the wood splitter is readily mounted thereto in an orientation having a hollow splitting screw cone with a starter tip parallel to the longitudinal axis of the unit. The cone is mounted over an impact drive unit which is coupled to the gearing arrangement to provide a safe reliable drive. This arrangement also permits a portable log splitting unit which is relatively inexpensive and simple to use and with the cone removed permits use as an impact tool.
