A log length measuring device for marking uniform lengths in logs. The log length measuring device includes an adjustable length arm. The arm is a telescoping arm. The arm has first portion and a second portion. A pair of marking members marks a log. Each of the marking members is coupled to one of an end of the arm. Each of the marking members comprises a block. Each of the blocks has a front surface, a first end and a second end. The first and second ends are opposing ends. Each of the first edges forms a pointed edge.

A quantity describing the wheel rpm is determined for at least one wheel in this method of determining a quantity describing the height of the center of gravity of a vehicle. A quantity describing wheel performance is determined for at least one wheel at least as a function of the quantity describing the wheel rpm of the corresponding wheel. A quantity describing the height of the center of gravity of the vehicle is determined at least as a function of the quantity that is determined for at least one wheel and describes wheel performance of this wheel. This method of determining the quantity describing the height of the center of gravity of a vehicle is used as part of a method of stabilizing the vehicle.

An adjustable tile spacing apparatus permits the setting tiles in a consistent pattern with perfect spacing relative to one another so as to obtain grout joints of uniform width. The adjustable tile spacing apparatus includes a central member and two perpendicular members at opposing ends of the central member, with each member adjustable in both width and length dimensions, via the use of telescoping members and fasteners. A spacer is affixed to each corner of the apparatus. The spacer can have an X-shape, a T-shape, an L-shape, or a linear shape. The spacers may be ¼ inch, ⅜ inch, and ⅛ inch in width to construct various sized grout line widths. A rubber handle with finger grips is provided for user comfort. The adjustable tile spacing apparatus is simply moved along as each tile is set and provides perfect spacing for the next tile to be set.

A removable tile spacer for use in properly spacing floor tiles, wall tiles, counter tiles, and other tiles having a uniform shape is provided with an integrally formed handle angled upwardly and away from the flat body of the tile spacer. The tile spacer handle projects at an angle upwardly and outwardly from a junction at the distal end of a selected one of a plurality of legs forming the tile spacer body. By locating the handle remote from the intersection of the tile spacer legs a level or straight edge can be used to properly align the tiles as they are placed on a flat, supporting surface without obstruction from the tile spacer of the invention. Also, by locating the handle for the tile spacer at the tip of one of its legs, the tile spacer is provided with an extended lever arm to facilitate removal of the tile spacer from between tiles, should removal prove difficult.

A tool is provided for facilitating angular alignment of a hydrofoil coupled to a mounting block having a flat bottom surface area. The mounting block is pivotally coupled to a cylindrical strut having a longitudinal axis. The tool has a saddle for engaging the cylindrical strut and a plate coupled to the saddle. The plate has an alignment edge that, when positioned by the saddle beneath the flat bottom surface area of the mounting block, forms a desired angle with respect to the longitudinal axis of the cylindrical strut.

A spacing tool for determining the spacing between adjacent members of a structure including a pair of perpendicular planes, the planes intersecting along a line offset from the centerline of each plane, the pair of perpendicular planes including a first planar member having a first width corresponding to a first desired spacing between adjacent members in a structure; and a second planar member having a second width corresponding to a second desired width between adjacent members in a structure, the second desired width being less than the first desired width. Each of the first and second planar members further includes a side edge, and the spacing tool further includes first and second thickness indicia positioned on the first planar member side edge and the second planar member side edge respectively. The indicia correspond to the first width and the second width.

A CMM calibrating gauge includes a block gauge which has a first end face and an opposite second end face and whose length absolute value has been certified, and a sphere fixed to a front surface of the block gauge. A method for calibrating a CMM using the CMM calibrating gauge includes the steps of bringing a probe of the CMM into contact with the first end face of the block gauge to specify planarity of the first end face, bringing the probe into contact with the peripheral surface and the pole point of the sphere to specify coordinates of the center of the sphere relative to the first end face and the diameter of the sphere, bringing the probe into contact with the second end face of the block gauge to measure planarity of the second end face, and bringing the probe into contact with the peripheral surface and the pole point of the sphere to measure coordinates of the center of the sphere relative to the second end face and the diameter of the sphere and revise the specified planarity of the first end face and the specified sphere center coordinates and sphere diameter, thereby specifying three-dimensional dimensions of the CMM calibrating gauge to calibrating the CMM.
摘要:
A calibration assembly and method for calibrating the device pick-up heads used in multi-head IC handlers such that all of the device pick-up heads are reliably calibrated to a consistent optimal calibration position. Gauge blocks are provided that greatly simplify the calibration process by holding the movable portion of a device pick-up head in an optimal calibration position relative to the base structure of the device pick-up head while the collar is secured. Each gauge block has base portion for supporting the base structure of the device pick-up head, and a flat contact surface against which the lower surface of the movable portion is pressed. The contact surface is a predetermined distance from the base portion such that when the device pick-up head is mounted on the gauge block, the movable portion is maintained in an optimal calibration position relative to the base structure.
