Abstract: A heat expandable baffle having a shape corresponding to, but smaller than, the shape of the cross section of a cavity to be sealed, and comprising a rigid support plate, a carrier for a heat expandable material and a heat expandable material mounted only to the outer periphery of the carrier. When activated by heating, the expandable material expand radially from the carrier to seal the cross sectional gap between the carrier and the cavity wall.

Abstract: A carrier-free expandable filler insert for filling or sealing a hollow space or cavity is provided. The insert comprises a self-supporting continuous structure that may be produced by contour extrusion molding or injection molding a polymer matrix containing a polymer and/or polymer precursor and a latent blowing agent. The expandable filler insert is secured to the interior surface of a vehicle pillar, for example, using a fixing element that may be integral with the self-supporting continuous structure, the polymer matrix thereafter being activated and expanded by heating.

Abstract: A watch case includes a middle-bezel having a non-circular upper opening receiving a glass of corresponding non-circular shape. The glass has an outwardly-directed peripheral flange able to pass with a slight play through the upper opening in the middle-bezel, and the middle-bezel has an inwardly-directed collar defining its upper opening. A packing seal is disposed with a part under the collar and a part resting on the flange. A screw-fitted circular back applies pressure to the glass to compress the seal between the collar and flange and thereby hold the glass in the upper opening.
