Abstract: An energy absorbing member that may be coupled to a chest protector like those worn by baseball or softball catchers and/or umpires is provided. The energy absorbing member may be releasably attachable with, or permanently sewn or riveted into, an upper central region of the chest protector. The energy absorbing member includes a backing plate having low elasticity that abuts the chest protector. The energy absorbing member further includes a front plate attached to the backing plate that preferably projects outwardly from the backing plate to form a hollow interior portion between the plates. The front plate is preferably an arcuate, convex plate that is able to distribute energy and deflects a batted or pitched ball so that absorbing member may absorb and distribute energy from the ball along the chest.

Abstract: Methods and apparatus for plugging cells of honeycomb structures are disclosed. A first method covers the honeycomb structure's end face with a mask having a body and plurality of sized openings positioned to oppose certain cell channels, wherein the outer edge of the body extends radially outwardly from the end face. A film also extends outwardly of the end face, and a plug of material is provided upon the film. The mask and film material are sealed to one another, and a force is applied to the film forcing the material through the mask and into the cells. Also disclosed is adhering a mask to a first end face of the honeycomb structure such that the mask has an outer portion that extends radially beyond an outer edge of the honeycomb; providing a volume of plugging material; clamping the outer portion between a first clamping portion and a second clamping portion; and transferring the plugging material into the honeycomb.
