Abstract: A bucking apparatus to be used in conjunction with a loader and topping saw that are mounted to a logging platform or trailer. The bucking apparatus is attached to the loader and includes a plurality of hatches. The hatches can be adjusted for different lengths so that different length logs can be cut when eliminating faults from the trees. The hatches of the bucking apparatus are measured to be particular distances from the topping saw and so, when a tree is pulled through the topping saw with the loader, the end being held can be aligned with one of the hatches, and then the saw can be engaged thus creating a log of the particular length.

Abstract: The disclosure provides apparatus and methods of use pertaining to a measurement template for use in allograft preparation and processing. Specifically, the template may be used to measure the trochlea angle of the trochlea groove of the distal human femur. The measurement template may be formed of a flat metal plate having first and second ends, each forming a different angle designed to fit against the trochlea groove and provide an indication of the angle of the groove in relation to the angles formed by the template. The trochlea angle of the allograft may then be documented, allowing for proper matching between allograft tissue and transplant recipient physiology. The measurement template may be adapted for a variety of configurations depending on desired and/or common allograft requirements. Other embodiments are also disclosed.

Abstract: An embodiment is an articulating straight-edge apparatus having an asymmetrical hub with a lobe having a flat edge. The hub has a bearing hole, an axle, a circular side with recesses which provide stopping at pre-set angles. There is a secant slotted channel through the lobe. The floor of the channel has depressions that provide stopping for translational shift. A connecting block is covered with a back and front plate. The block has an angle positioning SLD. The SLD impinges recesses as the hub is rotated. Additionally, there is a translational shift mechanism which includes a sliding rail in the channel. The rail has a SLD aligned to impinge a depression as the rail moves through the channel, therein stopping at a depression. Attached to the siding rail is a straight-edge element. The straight-edge serves as a carpenter's square, and can be adjusted angularly and translationally with manual force.

Abstract: A combination carpenter square and bevel/sliding bevel having three triangle-shaped adjoining legs, with an articulating joint between the hypotenuse leg and each adjoining leg. The other two non-hypotenuse legs are capable of forming a substantially 90 degree angle between the two non-hypotenuse legs to function as a carpenter's square.

Abstract: A combination carpenter square and bevel/sliding bevel having three triangle-shaped adjoining legs, with an articulating joint between the hypotenuse leg and each adjoining leg. The other two non-hypotenuse legs are capable of being latched or detached by a latching joint that, when latched, forms a substantially 90 degree angle between the two non-hypotenuse legs to function as a carpenter's square.

Abstract: A tool for accurately determining and setting angles using an x beam and a y beam that pivot about a common axis and may be locked in position relative to each other with an axle lock and by locking one leg of each beam to a slotted stabilizer bar. Index holes on the x beam and the y beam receive movable index pins between which measurements are taken. Trigonometric calculation may be used, or a precalculated reference book or data table may be consulted, to determine or set the angle between the x and y beams for various index pins separations, when the pins are located in the various combinations of x and y beam holes. Relatively course linear measurements permit very fine angular measurements and settings.

Abstract: An end of a rectangular scaled straight edge is pivotally connected to an end of a rectangular unscaled straight edge. The scaled straight edge has a longitudinal slot wherein a stem is retained by a compression lock. The stem passes through a hole in one end of a flat connecting bar that is disposed between a bearing of the compression lock and the scaled straight edge. The other end of the connecting bar is pivotally connected to the unscaled straight edge. When the lock is open, the stem is slidable within the slot, thereby providing an adjustable angle between the straight edges. When the lock is closed, the position of the stem is fixed within the slot, thereby sustaining a fixed angle between the straight edges.
