Abstract: Apparatus and method for grinding semiconductor chips and other specimens prior to microscopic examination thereof by supporting a specimen on a specimen mount, fixing the specimen mount to a lower end of a lower arm, connecting an upper end of the lower arm to a swingable arm by a horizontal pivot which permits the lower arm and specimen mount to move upwardly and downwardly relative to the swingable arm, providing a stop to limit downward movement of the specimen mount relative to the swingable arm when the lower arm reaches a zero position, moving the swingable arm downwardly to lower the specimen to engage an underlying rotatable grinding platen to define a zero position, and continuing to move the swingable arm downwardly beyond the zero position by an amount corresponding to the amount of material to be removed from a lower portion of the specimen so that the stop will prevent removal of additional material.

Abstract: A device for securing and holding live bait while it is applied to a fish hook. The bait holder is comprised of two sets of opposed slender fingers which mesh together without harm or injury to the bait. The fingers are curved to present concave surfaces towards the opposed set to center and position the bait for complete access to all portions of the bait for hook applying purposes.
