A static gasket assembly having a grid-like carrier (') formed as a mesh of overlapping strands. Openings (-) are created strategically in the carrier (&#x2032;) with the severed ends of the strands forming cantilever stems () projecting inwardly. Any one of a variety of specially configured sealing elements () are pressed into the respective openings (-) with the cantilever stems () engaging a peripheral groove () in each sealing element to retain the respective sealing elements in position. The gasket assembly is then placed over a surface to be sealed () and the carrier (&#x2032;) can either be removed, or remain as a permanent fixture of the gasket assembly.

Modular gasket

An accessory device for use with a microhardness tester to position a test surface of a sample in a focal plane of the microhardness tester is disclosed. The device comprises a frame having a base that attaches to a z-stage of a microhardness tester, and upstanding front and rear walls connected by a bridge wall spaced vertically from the base. The front and rear walls of the frame each have an inwardly protruding detent rail defining an engagement surface on an underside of the detent rail, wherein the respective engagement surfaces lie in a common plane that corresponds to the focal plane of an objective lens of the microhardness tester. A swivel stage is provided between the front and rear walls for carrying a test sample. The stage is movable automatically or manually to a test position wherein a test surface of the sample abuts with the engagement surfaces in the focal plane and a released position. The frame is preferably elongated in a lateral direction to slidably support a series of samples for successive testing.
