摘要:
A bow square for checking and recording the bracing height, nocking point, and locations for a kisser and peep sight of an archery bow. The device comprises an elongated plate provided with a graduated scale for measuring the bracing height, and a cross bar extending transversely of the elongated plate and having a scale extending parallel to the bowstring. A pointer mounted on a slidable bar may be moved along the scale on the cross bar to indicate the nocking point and the correct locations of the kisser, and peep sight. Marking receiving means are provided parallel to each scale for recording the correct locations and adjustments.

A handheld finger activated semi-automatic arm may include a barrel, a trigger, a moveable gun bolt and a trigger reset mechanism. The trigger reset mechanism may use rigid mechanical contact between the trigger and the gun bolt during an earliest portion of the operating cycle. The trigger may be blocked from depression by the gun bolt up to 99% of the operating cycle.

A method for sharpening radially extending teeth on a disk included: 1) sharpening a tooth by moving the disk relative to a cutting head, 2) separating the disk from the cutting head, 3) indexing the disk to the next tooth, 4) engaging the cutting head with the next tooth, and repeating steps 1)-4) until sharpening is complete. A machine for sharpening teeth includes: a table movable in the x-y plane, an angle plate mounted on the table for holding a disk, a digital indexer for rotating the disk, a cutting head for sharpening the teeth, and a computer for the controlling the movement of the disk relative to the cutting head by sequentially moving the disk via movement of the table and rotation of the disk on the angle plate. A rotary cutting head has a cutting element affixed at a periphery of the head.

An electronic device includes a silicon carbide layer including an n-type drift region therein, a contact forming a Schottky junction with the drift region, and a p-type junction barrier region on the silicon carbide layer. The p-type junction barrier region includes a p-type polysilicon region forming a P-N heterojunction with the drift region, and the p-type junction barrier region is electrically connected to the contact.

A realistically opening artificial flower has a slidable pusher basket having an upper end and a lower end and is moveable from a first position to a second position. The flower includes a means for moving the slidable pusher basket from the first position to the second position; the means is located generally adjacent the lower end of the slidable pusher basket. The flower also includes a simulated flower with a base that receives the upper end of the slidable pusher basket along with multiple rows of petals disposed on a plurality of vertically stacked supports. The slidable pusher basket is coupled with at least one of the plurality of vertically stacked supports via a petal attachment member. Incident to the slidable pusher basket moving from the first position to the second position, the multiple rows of petals transition from the generally closed position to the generally open position, and each row of petals has varying open and closed angles.

A spring bar assembly for connecting a stator core to a stator frame. The spring bar assembly includes an attachment member with a hole and a spring bar with a hole that aligns with the hole in the attachment member. A bolt passes through the hole in the attachment member and the hole in the spring bar, where the bolt is used to couple the attachment member to the spring bar.
