Abstract: The invention relates to a metal membrane filter (1) and to a method and apparatus for the production thereof. The metal membrane filter (1) has rectilinear, cylindrical filter pores (2), which are arranged statistically distributed on the metal membrane filter surface (3) in a density of from a single filter pore (2) per cm2 up to 107 filter pores (2) per cm2. The average diameter of the filter pores (2) is uniform for all filter pores (2) and is from a few tens of nm up to several micrometers. The metal membrane filter (1) comprises a metal electro-deposited with rectilinear, cylindrical filter pores (2) or a correspondingly electro-deposited metal alloy.

Abstract: The invention relates to a sheet material having metal points (8) and surfaces (2 and 3) located opposite one another, wherein the sheet material (1) has through-holes (4) from one surface (2) to the surface (3) located opposite. Those through-holes (4) are filled with needle-point-shaped conical pins (5) or through-contacts (6) of electrically conducting material, whereas the surrounding sheet material in a preferred embodiment of the invention consists of an insulating plastics material (7). In a further embodiment of the invention, instead of the insulating plastics material (7) there are provided needle-shaped pins that are surrounded by air or some other gaseous medium. The invention further relates to a method for the production of such a sheet material (1) and to forms of use of the sheet material (1).

Abstract: The invention relates to gas generator comprising an outer housing made of plastic, in which a pyrotechnic propellant charge and an igniter having its own igniter housing are accommodated. The igniter housing consists at least partially of plastic and is welded with the outer housing.

Abstract: The invention relates to a pyrotechnic gas generator comprising a gas-tight outer housing consisting of at least two parts, a first part of which being a receiving part for pyrotechnic material and a second part of which being a base part which is connected with the receiving part by welding so as to form the outer housing. One of both parts has a radially projecting, surrounding flange with an outer peripheral edge and the other part has an axially extending, rim-like projection circumferentially surrounding said peripheral edge and having an inner surface which is contacted by the peripheral edge. The welding of the first and second parts is provided at the flange.

Abstract: In a method of manufacturing foils of plastic material which are electrically conductive in a transverse direction, but not in the plane of the foil wherein micropassages are formed in the foil by etching nucleus traces which are generated by exposure to a heavy ion beam, conductive layers are deposited on one side of the foil and the micropassages are filled by electrolytic metal ion depositions from the other side until caps are formed on the passages. After dissolving the two conductive layers, the steps are repeated to form caps also on the passages at the other side of the foil so as to provide for good contacting capabilities at both sides of the foil.
