Abstract: Systems, methods, and devices provide for a bone centering drill guide. The bone centering drill guide may include a clamping mechanism which clamps to a bone in a pivotable fashion. The proximal end of the clamping mechanism includes a handle portion having a first arm and a second arm which is configured to allow a user to grip the device and exert force which urges the first and second arms toward each other. The distal end includes a clamping portion having first and second arms which are urged into a closed configuration when closing force is provided to the handle portion. The proximal end may further include a locking mechanism which locks the clamping device in a clamped configuration. The bone centering drill guide may further include a guide slot disposed on the distal end above the clamping arms, the slot configured to remain centered between the first and second clamping arms.

Abstract: An electromechanical vault cartridge receptacle has an opening for inserting a vault cartridge, the cartridge passing between a pair of laterally biased rollers which continuously engage asymmetrically contoured sided surfaces of the cartridge. A front surface edge of the cartridge bears upon and causes the backwards motion of a movable frame, the motion of which causes top and bottom surfaces of the cartridge to be securely engaged between an opposed pair of horizontally planar cartridge bearing members. The backwards motion of the movable frame also results in roller supporting members to be locked when the cartridge is fully inserted, thereby preventing lateral movement of the rollers. A cartridge ejecting means comprises electromechanical means adapted for engaging a back surface of the movable frame to move the movable frame in a forwards direction, disengaging the cartridge engaging members and unlocking the roller supporting members, whereby the cartridge is pushed back out of the opening.

Abstract: An electromechanical vault cartridge receptacle has an opening for inserting a vault cartridge, the cartridge passing between a pair of laterally biased rollers which continuously engage asymmetrically contoured sided surfaces of the cartridge. A front surface edge of the cartridge bears upon and causes the backwards motion of a movable frame, the motion of which causes top and bottom surfaces of the cartridge to be securely engaged between an opposed pair of horizontally planar cartridge bearing members. The bearing members comprise conductive plate means which are brought into registration with corresponding plate means beneath top and bottom surfaces of the cartridge for defining signal coupling capacitors. The backwards motion of the movable frame also results in roller supporting members to be locked when the cartridge is fully inserted, thereby preventing lateral movement of the rollers.

Abstract: A pair of work engaging jaws of a clamp device are interconnected by linkages forming part of a manually operable force multiplying mechanism. A movable work engaging element mounted by one of the jaws, is actuated by a grip lever from a retracted position into engagement with a workpiece. An over-center linkage transmits the actuating force against the resistance of a spring to prevent return of the grip lever from its actuated position. A release lever is actuated to cam the grip lever and retract the work engaging element.
