Peter Kroker has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).
Abstract: A vent, preferably made of metal, comprises a body (10) having an aperture (24) for the passage of a fluid and a sealing surface (11) surrounding the aperture. A porous membrane (50) lies against the sealing surface (11) and covers the aperture (24). A clamp arrangement may comprise a spring (30) pressing the membrane against the sealing surface (11) to prevent liquid from passing through between the sealing surface (11) and the membrane (50), e.g. by means of a cap (40) secured to the body (10) of the vent. The clamp arrangement is such that upon a reduction of the membrane thickness by 50% in the clamping area the compressive force per unit area does not change by more than 50%.
