Abstract: A linear stepper motor includes a stator, a rotor, a cover and a longitudinally displaceable actuating rod. The stator is formed as a fully overmoulded stator assembly. The stator assembly includes a stator overmould. The rotor is received in the stator and includes a spindle. The cover is coupled to the stator assembly on the drive side of the linear stepper motor. The actuating rod is guided by the stator assembly. The spindle is only supported by its tips between two bearing balls between a stator recess of the stator overmould and a cover recess in the cover. A device and a method for manufacturing the linear stepper motor are also provided.

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: A compressor in a multi-stage axial form of construction, with a rotor which is mounted overhung and includes a plurality of moving-blade rings on blade carriers connected to one another, and with a blade arrangement, in which the moving-blade ring of the first stage forms the blade cascade arranged furthest upstream. At least one of the rotating blade carriers is produced in an MMC form of construction, that is to say as a metal component fiber-reinforced at least in regions, and the rotary bearing absorbing the large part of the radial loads occurring on the rotor has a predetermined breaking point which, when a defined radial load is exceeded, allows a radial shift of the rotor, with the result that the latter brushes against the stator.
