Abstract: A burner membrane comprising a textile fabric. The textile fabric comprising at least 60% by weight of machined metal fiber bundles, having a bundle voluminousity in the range of 1 to 15% and a torsion rate in the range of 10 to 80 turns/m.

Abstract: The invention relates to a burner membrane comprising at least one layer consisting of a compressed, needled fibre web with a porosity of between 60% and 95%, and that is constructed of heat-resistant stainless steel fibres. Moreover, the invention relates to a method for its manufacture, comprising the steps of providing a fibre web composed of heat-resistant stainless steel fibres, needling the fibre web, and compressing the needled fibre web to the desired porosity.

Abstract: A yarn (21) comprising polymer or natural fibers (25) and one or more consolidated machined metal fiber (22) bundles is provided. The yarn is characterized in that the consolidated machined metal fiber bundles (22) are substantially surrounded by the polymer or natural fibers (25). Further the use of a textile fabric out of these yarns as a gas burner membrane is described.

Abstract: A gas burner membrane is provided. The membrane comprises a textile woven, braided or knitted fabric. This membrane further comprises different combustion zones on its burner surface. A method to provide such gas burner membrane is described.

Abstract: A surface burner for gas has a gas supply chamber (5) provided with a gas outlet side enclosed by a conically shaped burner membrane (2) fixed to a support net (1). A coupling element (3) connects the chamber (5) with gas supply (4). The burner membrane (2) includes a non-sintered fabric-type structure made of heat resistant stainless steel fiber bundles of individual fibers, wherein the individual fibers have a substantially parallel arrangement and an equivalent fiber diameter of between 1 and 150 .mu.m.

Abstract: Textile fabrics are formed of bundles of machined metal filaments disposed in nearly parallel arrangement in the bundles. The machined filaments have a predominantly quadrilateral cross-section, and an equivalent filament diameter of between 15 and 150 .mu.m, where the equivalent diameter is the diameter of a circle having the same surface area as the surface area of a filament cross-section.

Abstract: Heterogeneous custom knitted fabric for lining the surfaces of molds includes predetermined surface zones with different knitted patterns. The knitted fabric can be utilized in devices designed for the shaping of, for example, plates of glass.

Abstract: A safety valve responding to overheating conditions of the surrounding atmosphere, more specifically a combustion gas inlet valve that closes when a fire declares. The valve uses a shape-memory element for detection and command. For the latter function it must be inside the valve, at the expense of sufficiently rapid detection of external temperature. This problem is solved by using a shape-memory element that is in close contact with the valve housing, e.g. countersunk in a groove in the internal wall of the valve housing, for facilitating conduction heat transfer.

Abstract: A warning device for indicating a predetermined temperature level of a solid object includes inner and outer concentric telescoping tubes having outer surfaces of different and contrasting appearances; a heat-conducting device for fixing one of the tubes to the solid object; a temperature-responsive spring element disposed within and abutting each of the tubes, the spring element being made of a material having shape memory properties such that upon an increase in temperature it expands and causes outward telescopic movement of one tube relative to the other tube to thereby expose the outer surface of the inner tube to view.
