The present invention is generally directed to a reduced shock breakaway screw for use with medical implants and the like having improved solid wall geometry in the breakaway area between the upper and lower portions of the set screw. This improved geometry serves to slow down the fracturing process during shearing, thereby increasing the proportion of energy dissipated as heat from plastic deformation of the material to the amount of energy released as kinetic energy from elastic rebound.

Minimal shock set screw

A reduced shock breakaway set screw for use with medical implants and constructs for the spine having improved geometry of the groove area between the upper head portion and lower threaded portion of the set screw. The groove area of the set screw has circular and noncircular portions which in at least one embodiment comprise upper and lower radii separated by a flattened groove bottom. Other embodiments have apertures running between the groove area and an internal cylindrical bore and/or ridges or ribs running across the groove area. The improved geometry serves to slow down the fracturing process during shearing thereby increasing the proportion of energy dissipated as heat from plastic deformation of the material to the amount of energy released as kinetic energy from elastic deformation, thus reducing shock to the patient and physician without changing the preset break-off torque for the set screw.

A drum for a clothes dryer includes a generally cylindrical sidewall rotatable about a horizontal axis. The sidewall has an outer wall and an inner wall. The inner wall defines an interior volume for receiving articles to be dried. A hanger mechanism is coupled to the inner wall. The hanger mechanism is configured to support items hanged therefrom for drying without rotation of the drum. A shelf is coupled to the inner wall. The shelf is movable between a retracted position and an extended position. When extended, the shelf is configured to support articles to be dried. The drum is stationary during drying cycles wherein the hanger mechanism and the retractable shelf are in use. A heat source is operated at a reduced power level when the drum is not rotated.
