  • Patent number: 7716843
    Abstract: A flat transparent overlay for measurement of equine foot x-rays employs a flat lower edge for alignment with a ground surface and an anterior edge angled to approximate a hoof distal wall. A first sight ring positions the tool over a tip of an image of a third phalanx. Six interrelated scales are provided for measurement of the palmar cortex, distal sole thickness, break-over distance and coronet band to extensor process distance, and in conjunction with a second site ring, center of rotation and palmar sole thickness. A first protractor element is centered posterior on the first sight ring for measurement of the palmar angle. A dual scale extends from the angled anterior edge portion with a measurement line for measurement of the hoof-lamella zone. A second protractor element is posterior to and centered on the second sight ring for measurement of a pastern angle.

  • Patent number: 5205045
    Abstract: A tile cutting gauge comprises mainly a semi-circular protractor and a guide rod pivotally fastened to the protractor. A length ruler is slidably mounted on the straight side of the protractor, while a baffle means is slidably mounted to the guide rod in such a manner that it can be moved upward, downward, leftward, and rightward. The desired length and angle of the tile intended to be cut are measured respectively by means of the length ruler and the guide rod. The tile intended to be cut is held securely by the length ruler and a baffle means so as to permit an operator to make a cutting mark on the tile along the guide rod.
