Abstract: A damping plate consists of at least one metal plate and has a pressure-transferring surface that applies offset pressure to a damping plate. The pressure-transferring surface has at least two areas with different degrees of resilience, and it can be placed at least in sections on a pressure-applying unit starting at least at a set pressure distributed over the entire pressure surface.

Abstract: A brake pad assembly comprises a backplate, a friction lining secured to one side of the backplate and a planar dampening sheet secured to the other side of the backplate. The dampening sheet has at least one embossed projection extending from the one side thereof and the backplate has at least one recess in the side thereof secured to the dampening sheet and which is of generally the same configuration as the projection in the dampening sheet to receive the projection. The projection is partially outlined by at least one cut in the dampening sheet forming a cut edge on the projection which extends outside the plane of the dampening sheet to abut against the wall of the recess and compensate for excessive shearing forces caused between the dampening sheet and the backplate during a braking operation utilizing the brake pad assembly.

Abstract: A double-walled or quadruple-walled foil bag (8) for receiving a liquid, more particularly beer, which is to be arranged in a preferably spherical pressure tank, consists of flat, superposed, circular or polygonal foil pieces (2a-2c) which are welded together at the edge. The foil pieces which form a foil bag half (8a, 8b) are provided in the central area with a connecting piece (5) which penetrates them. The foil pieces, which form the double or quadruple wall, are preferably cut out of a flattened, commercially available foil tube. In order to test the finished foil bag for imperviousness, only an annular peripheral area which runs next to the weld seam (6) and which is connected via a connecting channel with a central area surrounding the connecting piece (5) is inflated.
