  • Patent number: 11896238
    Abstract: A mill head for replaceable attachment to a base so as to collectively form a bone mill. The mill head includes shell with: a first opening in which bone stock is introduced into the head; and a second opening through which the bone chips are discharged. A cutting device is mounted in the shell to both rotate and move laterally. Attached to the cutting device are coupling features for engaging a drive spindle able to rotate the cutting device. Also attached to the housing is an alignment feature. The alignment feature engages a complementary alignment feature associated with the drive spindle so as a result of the engagement of the alignment features, the cutting device moves within the shell so that the cutting device coupling features are positioned to engage the drive spindle.

  • Patent number: 9655631
    Abstract: A mill head for replaceable attachment to a base so as to collectively form a bone mill. The mill head includes: a first opening in which bone stock is introduced into the head; a cutting device that converts the bone stock into bone chips; a second opening through which the bone chips are discharged; and a third opening through which a motor integral with the base is attached to the cutting device. Internal to the mill head are containment rings. The containment rings prevent the discharge of material through the third opening. The containment rings are services the internal component of the mill head on which the cutting device rests.

  • Publication number: 20050017561
    Abstract: The seat back of a seat is attached to a seat recliner mechanism. As the seat back is moved, it moves in a curvilinear motion centered about or near the seat H-Point. The seat recliner mechanism, attached to the seat back, has arcuate slots. The center of the curves of these arcuate slots are located at or near the seat H-Point. A seat recliner system has two seat recliner mechanisms operating in tandem.

  • Patent number: 5042360
    Abstract: The present invention relates to a regenerative hydraulic starter/speed regulator system for providing initial rotation and acceleration of a rotatable barrel cluster of a gun gas driven Gatling gun, and for controlling the speed of the barrel cluster during the firing of the gun. The hydraulic system includes a high pressure accumulator for containing a supply of pressurized hydraulic fluid. A hydraulic motor/pump unit is connected to either drive or be driven by the barrel cluster, depending on whether the motor/pump unit is operated in either the motoring or pumping mode. Initially, a servo mechanism operates the motor/pump unit in the motoring mode wherein pressurized fluid from the accumulator is supplied to the motor/pump unit to initially rotate and accelerate the barrel cluster in a firing direction until the rotation of the barrel cluster is sustained by the gun gas drive unit.
