Abstract: A surgical drill for use with a drill bit. The drill includes a handpiece with a motor and a brake mechanism. The brake mechanism is a sliding rack adjacent a first end and a second end with a stop adjacent the drill bit. An actuator is mounted to the handpiece and a plunger is coupled to the actuator. A sensor asserts a signal when the drill bit penetrates bone. When the sensor asserts the signal indicting the drill bit penetrated bone, the actuator moves the plunger into engagement with the rack to prevent further insertion of the drill bit.

Abstract: A wire driver for driving a wire or pin into living tissue includes a rotating drive shaft, a collet, and a wedge. The collet is held fast to the drive shaft and has a plurality of feet radially moveable relative for grasping the wire or pin. Each foot has an outwardly located curved ankle surface with a concave or convex profile. The wedge is disposed over the collet and is at least partly inside the bore of the drive shaft. The wedge rotates with the drive shaft and has a tapered inner surface in selective engagement with the curved ankle surfaces. The wedge is moveable longitudinally relative to the collet feet to bear against the feet and cause the feet to grasp the wire or pin. The wedge has a release position in which the wedge is spaced from the collet feet, releasing the wire or pin.

Abstract: A laundry treating appliance having a drum, defining a treating chamber, with a lifter and a balancing system having at least one balancing ring and a reservoir located in the lifter and a liquid supply system fluidly coupled to the reservoir. Liquid may be supplied to the ring and to the reservoir through the ring to offset an imbalance in a laundry load located within the drum.

Abstract: A method of determining static and dynamic imbalance conditions in a horizontal axis washing machine utilizes a number of dynamic algorithms to automatically determine the total load size, the magnitude of any static load imbalance, and the magnitude of any dynamic load imbalance for any given load in a given washing machine based on power measurements from the washing machine motor obtained in predetermined speed profiles.

Abstract: A food mixer having a planetary gear system. The mixer comprises a vertically extending stand housing an electric motor, a base to support the stand, an overhang arm connected to the stand, and a gear system housed in the overhang arm. The gear system includes a center shaft having a center gear mounted thereto, the center shaft being drivingly coupled to the motor and rotatable about its axis. The gear system further includes an agitator shaft having an agitator gear mounted on an end thereto, the agitator shaft being oriented generally parallel to the center shaft and located such that the agitator gear meshes with the center gear. The gear further includes a ring gear having a set of internal gear teeth, the ring gear encircling the center gear and the agitator gear whereby the agitator gear meshes with the ring gear.

Abstract: The invention is a lock for the bowl support of a food mixing machine. After the bowl is raised into the mixing position, the lock ensures that the bowl maintains its position and is not subject to creep. The mixing machine comprises a mixing head, a mixing bowl support for supporting a mixing bowl under the mixing head, a gear train for moving the bowl support and mixing bowl into position beneath the mixing head, and a lock which engages the gear train to prevent the bowl support from moving out of position beneath the mixing head during mixing. The lock is preferably a pawl which engages one of the gears in the gear train, preventing the bowl and the bowl support from moving out of position.
