摘要:
A blender for blending foodstuff comprising a motor housing that encloses an electric motor and has a first end and a second end. An upper housing is attached to the first end of the motor housing. The motor housing includes a fan driven by the motor controlled by a plurality of switches positioned behind a flexible cover. A transparent base having translucent base feet and an open bottom partially surrounds the motor housing and has a first end. The first end of the base is clamped between the upper housing and the first end of the motor housing to thereby solely suspend the motor housing from the first end of the base. A shroud is positioned partially around the motor within the motor housing. The fan draws air through the open bottom of the base into the second end of the motor housing and then around and outside of the shroud into the open top of the shroud to thereby cool the motor. The air is then directed out through the open side portion of the shroud and then sealingly vented to atmosphere.

A strain gauge apparatus for measuring stresses on a rotating blade includes a strain gauge assembly, a shaft connectable to the rotating blade, a slip ring connected to the shaft, and a sleeve for covering lead wires routed along the shaft from the strain gauge and connected to the slip ring. The present invention also relates to a method of determining the fatigue life of a rotating blade.

An appliance button for use in an appliance having a housing, a button opening in the housing and a control structure within the housing includes a button that has a longitudinal axis. A distal end of the button extends outwardly through the button opening in the housing. A button stem is located within the housing and is generally co-axially aligned with the button. A first end of the button stem is operably connected to the control structure and a second end is operably connected to the button. A deflector is mounted on the button between the control structure and the housing and extends radially outwardly from the button to direct liquid away from the button stem.

An appliance button for use in an appliance that has a housing, a button opening in the housing and a control structure within the housing. The appliance button includes a push button with a distal end of the push button that extends outwardly through the button opening in the housing. A button stem is located within the housing and is aligned with the push button. A proximal end of the button stem is operably connected to the control structure. A deflector is located within the housing and positioned between the button stem and the push button.

A hand-held power tool includes an elongate shaft, a mounting structure disposed on one end of the elongate shaft, a cutting element, a prime mover, and an adjustable debris shield. The mounting structure has a rotation axis at an angle relative to the longitudinal axis of the elongate shaft. The cutting element is mounted to the mounting structure and includes at least one of a cutting line assembly and a rotary blade. The prime mover drives the mounting assembly to rotate the cutting element about the rotation axis. The adjustable debris shield has a first operative mode and a second operative mode. The adjustable debris shield has a first lateral span relative to the longitudinal axis when in the first operative mode and a second lateral span relative to the longitudinal axis when in the second operative mode. The second lateral is greater than the first lateral span.

A shield apparatus for use with a powered vegetation trimmer of the type including a trimmer head assembly having an output shaft and a cutting mechanism rotatable with the output shaft. The shield apparatus is mounted coaxially about the output shaft between the cutting mechanism and a head portion of the head assembly. The shield includes first and second outer walls coaxially disposed about the axis of rotation of the output shaft. The first outer wall circumscribes at least a portion of the cutting element to define a distal annular gap. The second outer wall circumscribes at least a portion of the head portion of the head assembly to define a proximal annular gap. The shield isolates the output shaft from the area surrounding the cutting mechanism so as to prevent vegetative matter from contacting the output shaft, or at least minimize such contact.
