Abstract: The aim is to devise a gas plug connector that permits a gas plug to be connected or disconnected only when an additional shut-off valve has been manually closed. To that end the housing (1) of the gas plug connector has a bearing (36) for a switching element (35) that on the one hand is fitted with a guide device (37), on which one end of a plunger (11; 12) installed in the base (2) of the housing (1) is supported, whereas the other end of the plunger (11: 12) is connected to a valve head (15) of a shut-off valve (8) positioned in the gas-carrying chamber (7) of the base (2). On the other hand, the switching element (35) is connected to a locking device, by means of which an insertion of the gas plug (57) dependent on the position of the switching element (35) can be prevented.

Abstract: A gas socket is to be provided which can be used for surface installation. The final installation of the gas socket must still be possible after the construction of the installation site has been fully completed. Replacement of the externally visible area of the gas socket shall also be possible. For this purpose, the gas socket comprises a housing (1), a shutoff device (10), a retaining element (29) and a cover (35) open on its face-side. The housing (1) is mounted in a torsion-proof way in the retaining element (29) which is connected with the wall (28) in a stationary way. The shutoff device (10) can be mounted on the retaining element (29). The cover (35) has an opening (36) in one of its side walls for an inlet port (2) and otherwise surrounds the housing (1) in a freely movable way, while it is supported on the wall (28) on the one hand and on the shutoff device (10) on the other when the shutoff device (10) is fastened.

Abstract: In a blister pack comprising a base foil with chambers formed therein for receiving a product sealed into the chambers, a rupture foil disposed on the base foil to close and seal the chambers and a plastic foil disposed on the rupture foil for the protection of the rupture foil, wherein the plastic foil is attached to the rupture foil with a retaining force which is lower than the force with which the rupture foil is attached to the base foil, except for a limited edge area of the rupture foil which is delimited by a seal edge and a perforation extending along the seal edge, so that, upon removal of the plastic foil and the rupture foil from the base foil in the limited edge area where the rupture foil is not attached to the base foil, the rupture foil breaks away from the plastic foil when reaching the perforated seal edge so that the chamber remains reliably covered by the rupture foil while the plastic foil is peeled off the rupture foil.

Abstract: It shall be created a gas plug connector that allows a positional adjustment of the same in relation to the outer wall surface and in this way enables compensation of positional setoffs as regards the stationary gas pipe installation. To achieve this, the gas plug connector comprises a casing (1), a shut-off device (2) and a fastening element (3). The tube-shaped nozzle (12) of the shut-off device (2) protrudes in a gas-tight manner into the casing (1) which has in its interior a groove (8) inside which rests a spring holding ring (10). Said holding ring (10) allows the nozzle (12) to slip into the casing (1), but prevents the nozzle (12) from slipping out of the casing (1). The fastening element (3) is on its one side attached to the wall (31) and on its other side to the shut-off device (2).

Abstract: In an apparatus for applying a cover foil to a bottom foil having a containment structure formed therein, the containment structure is formed into sections of the bottom foil in a molding tool through which the bottom foil is moved section-by-section. The bottom foil is then guided over an application roller which has depressions in which the containments formed into the bottom foil are received while a cover foil is applied to the bottom foil. The depressions in the application roller are arranged, in the circumferential direction of the application roller at a slightly larger distance from one another than the containments formed into the bottom foil so that the bottom foil is slightly stretched on the application roller. Means are provided for adjusting the lengths of the bottom foil section moved through the molding tool depending on the position of the cover foil relative to the bottom foil.

Abstract: The invention takes as its basis the problem of creating a safety sealing device for gas pipes by which the bearing of the valve body should be frictionless, require no maintenance and which causes only minimal flow resistance. Further the safety sealing device should not require outward sealing connections. It should be easy to install and able to be fitted into existing gas piping or fittings without having to change them.The problem is solved in that with safety sealing devices with a valve body (6) which can be pressed against a valve seat (1), whereby the valve body (6) is supported so that it is movable in the axial direction of the valve seat (1) is against the force of a locking spring (8), the valve body is conducted only through a spring and is otherwise freely movable without additional support points.The invention concerns a safety sealing device for closing gas conduits in cases of damage, e.g.

Abstract: A nozzle vane assembly for a gas turbine exhibits a number of circumferentially spaced vanes connected to a shroud. A second, concentric shroud is arranged separately and urged axially against the unrestrained ends of the vanes through a spring loaded clamping device. This arrangement serves to alleviate thermal stresses and thermal fatigue in the vane assembly.

Abstract: A thermal turbomachine casing having a multilayer heat insulation liner including a metallic bond coat in direct contact with the casing wall, a ceramic heat insulation layer bonded to the bond coat, and preferably an abradable coating in the form of a porous, predominantly metallic, top layer bonded to the ceramic layer. A metallic honeycomb may be fixed to the casing wall, in which case the bond coat, ceramic layer, and top layer are within the cells of the honeycomb. The bond coat and ceramic layer may partially or completely fill the honeycomb cells. The layers may be deposited by flame or plasma spraying, preferably after peening the casing wall. Each succeeding layer is deposited before any cooling of the preceeding layer.

Abstract: A method of, and apparatus for, generating a relief-like contrast at microscopic images or micrographs of a transparent phase object, wherein the object is obliquely illuminated at one side with respect to the plane of the object and observed during transillumination. For illuminating the object there are employed mutually incoherent beams of light rays possessing axes which are essentially parallel to one another.The microscope for the performance of the aforesaid method aspects embodies an object illumination device encompassing a light source and a light conductor formed of a bundle of glass fibers, the light radiating end of which is arranged at the direct neighborhood of the point of intersection of the optical axis of the objective of the microscope with the object slide or support and encloses with such axis an angle which is preferably in the range of about 40.degree. to 50.degree..
