Abstract:
A rotary tool includes a housing defining at least one slot and a motor including an output shaft supported within the housing. A collet chuck is coupled to the output shaft that is configured to slidably receive a collet. The collet chuck includes at least one lever arm configured to apply a clamping force to the collet. A wedge is configured to move into and out of engagement with the at least one lever arm to generate the clamping force. A bearing is attached to the wedge, and a yoke member is attached to the bearing. The yoke member includes at least one lever structure that projects outwardly from the yoke member through the slot in the housing.
Abstract:
An accessory tool retention assembly for a rotary tool includes a collet having a body defining a collet axis and having a plurality of flexible segments that extend longitudinal along the body generally parallel to the collet axis, each flexible segment including a curved end portion that curves radially outwardly from the collet body. A collet chuck is configured to be coupled to an output shaft of a motor of a rotary tool. The collet chuck defines a collet receiving passage configured to slidably receive the collet. A front wall portion on the collet chuck defines an insertion opening aligned with the passage of the collet chuck. The front wall portion defines a plurality of recesses sized and shaped complementary to the curved end portions of the collet. The plurality of recesses is positioned to receive the curved end portions when the collet is inserted into the collet receiving passage.

Abstract:
A rotary tool for coupling with a rotary tool accessory includes a motor and a power shaft operably coupled with the motor. A collet is operably coupled to the power shaft, the collet including a longitudinally extending inner surface portion. A nickel based bonding material is affixed to the longitudinally extending inner surface portion. A plurality of abrasive particles extend outwardly of the bonding material on the longitudinally extending inner surface portion, wherein generally between about 30 percent and about 55 percent of each abrasive particle of the plurality of abrasive particles extends outwardly of the nickel based bonding material.
Abstract:
An improved shoulder brace having a pair of shock absorbing saddle assemblies and cups for protecting the acromioclavicular and glenohumeral joints is disclosed herein. Each saddle assembly includes a resilient, ring-shaped member for seating over and conforming to its respective acromioclavicular joint. The cups overlie each saddle assembly, and form a shock absorbing air space over each saddle assembly. Additionally, each cup includes anterior and posterior portions for protecting the front of the glenohumeral joint, and the back of the scapula respectively. Finally, each saddle assembly includes an upper arm pad which is attached to its respective saddle by means of an omni-directional hinge joint. The improved shoulder brace provides lightweight and effective protection for the shoulder joints without impairing the agility of the athlete.

Abstract:
An aircraft with an aircraft elastic aerostructure body inflight aerodynamically initiated transient lateral modal bending response suppression system is provided. The aircraft elastic aerostructure body has an inflight aerodynamically initiated transient lateral modal bending response which is suppressed by the transient lateral modal bending response suppression system. The aircraft transient lateral modal bending response suppression system includes a sensor for sensing the inflight aerodynamically initiated transient lateral modal bending response and an electromagnetic moving mass shaker, the electromagnetic moving mass shaker having a moving mass and a mounting base, with the moving mass shaker mounted to the elastic aerostructure body with the mounting base. The system includes a controller wherein the first sensor outputs a sensed lateral modal bending response signal into the controller and the controller electromagnetically drives the electromagnetic moving mass shaker to suppress the lateral modal bending response.
