Title: Pressurised foam encapsulation for signalling appts. - using felt plate with perforated antistick foil for surface venting
Inventor: HANNSTEIN GUENTER
IPC: B29C44/18
Filed: 1979-09-26
Abstract: Pressurised cellular plastic, esp. for encapsulating communication modules for railway back-circuit signalling, is produced by mixing the foam forming components and filling them in a quantity, which suffices for the volumn of the appliance, into the open casing. The rising foam is slowed down over the full area by applying between the edge of the casing and a pressure absorption plate a plate of felt which has at least on one side a perforated anti-stick foil. This creates an adequately compacted foam without cavities which has a surface-free from bubbles. When attached to railway track, such encapsulation provides protection against moisture and shock loads.

Patent DE-3105406-A1 (DE)
Title: Conical self-sealing inner-pipe socket connection, and a centring device for double pipes (double-pipe systems)
Inventor: SANDL HERGEN
IPC: F24D3/10
Filed: 1981-02-14
Abstract: In heating, sanitary, cooling and process technology, the "two or double-pipe system" is predominantly used, with significant disadvantages, such as difficult and complex installation, large space requirement, a large number of attachments, large insulating surfaces, difficult branches on the same level and extensive mounting. No inner-pipe connecting pieces which are easy to install are known for double-pipe systems. These disadvantages are overcome according to the invention in that the "two-pipe system" is replaced by a double pipe. A self-sealing inner-pipe socket having a centre/depth stop incorporated (Item 5.2) is used to connect the double pipes. The inner-pipe socket is pressed onto the inner pipe with an additional force and seals said inner pipe, by deformation, within the conically machined surfaces (Item 5.1) of the inner-pipe socket. The outer pipe can then be connected and sealed by any known means. In double-pipe mouldings and connecting pieces, the inner-pipe socket can at the same time centre these fittings. In addition, loose/displaceable individual centring rings having at least three webs are used for centring the inner pipe. These webs at the same time act as a centre/depth stop for the outer pipes. <IMAGE>
