Abstract: In a radio communication system with at least one radio network control device, at least one base station is connected to at least one user station by a radio communication interface. The base station(s) and the radio network control device are components of a base station subsystem. The radio network control device is connected to an access device for a core network. The radio network control device and the user station(s) have a service specific key that is preferably valid for several user stations, or in other words, the service specific key is not user specific.

Abstract: The invention relates to a method for increasing the precision during the determination of system parameters dependent on the propagation delay, e.g. for a positional determination, in a mobile communications system with emission diversity, according to which a subscriber data signal and a reference signal are assigned to a subscriber. The subscriber data signal is emitted by at least two antenna devices on the emission side, whereas the reference signal is emitted exclusively by one antenna device on the emission side. The reference signal is used to precisely determine signal propagation delays, upon which the system parameters depend.

Abstract: The invention relates to an electromechanical lock cylinder, which interacts with evaluating electronics for recognizing an access authorization and comprises a housing that has two opposing cylindrical cavities (12). A lock core, which can be actuated by a key, or a knob shaft (11), which is joined to a knob in a rotationally fixed manner, is rotationally mounted in said cavities. The lock core and/or knob shaft (11) interact with a lock lug (13), which actuates, in particular, a bolt or latch of a door lock. When the key fits or in the event of a successful access authorization, an electromechanically driven blocking or coupling element (14) is moved out of the position of rest into an angular position, and a rotationally fixed joining between the key or knob and the lock lug (13) is effected. The invention is characterized in that the lock lug (13), when the blocking or coupling element (14) is in a position of rest, can be freely rotated relative to both lock cores or to both knob shafts (11).

Abstract: A process for producing thin absorbent planar structures which may be used in hygiene products such as diapers, incontinence products, wound contact materials or sanitary napkins to absorb body fluids, comprises the steps of: A) producing a mixture of an adhesive in dispersion form and a particulate absorbent by fluidizing the components, B) applying the mixture of adhesive and absorbent uniformly to the surface of one side of a first planar backing material, C) one side of a second planar backing material is applied to the mixture of adhesive and absorbent that is present on the surface of one side of the first planar backing material, so producing a sandwichlike intermediate, and D) the sandwichlike intermediate is processed to the end product at a temperature of at least 90° C., a pressure of from 4 to 50 bar, and a pressing time of from 0.5 to 5 min.

Abstract: In a coupling for the connection of a washing-liquid pipe in a motor vehicle to another component, a catching element (3) designed for connecting two coupling parts (1, 2) has a shell (9) of C-shaped cross section intended for gripping. Catching noses (6) project radially inwardly from the shell (9). By this, mounting and demounting of the catching element (3) are especially simple.

Abstract: A piston, which has a piston rod, is guided with freedom of axial movement in a cylindrical pressure tube. At one end of the pressure tube, the piston rod passes through an opening in an end wall, which closes off the end of the pressure tube. The pressure tube is surrounded by a heat-shrink sleeve, which, at the exit end of the piston rod, extends more-or-less radially inward and has a pass-through opening through which the piston rod extends. The ring-shaped end surface at the piston rod exit end of the pressure tube is enclosed by the heat-shrink sleeve.

Abstract: A locking-mechanism control means having a push rod which controls the adjustment of door-mounted catches, it being possible for the catches to be locked in relation to the door frame, having a first and a second adjustable blocking device arranged in the door. It is further possible for said blocking devices to be adjusted in dependence on the door movement, and one of the blocking devices arresting the push rod in the open position when the door is open. A driver is provided on the push rod and can be coupled to a rod which executes a movement corresponding to the push rod in order for an arresting unit, which engages with the door in the closed state of the latter, to be displaced out of engagement with the door in the open position of the latter.

At least one plate composed of an insulating material is disposed in or adjacent to the arc splitter stack, an external circumference of the plate does not project beyond the external circumference of the arc splitter plates, and the plate has an internal recess.

Abstract: In the case of a fluidic nozzle (12) a nozzle body (13) is fixed in a housing (17) by a form-locking latching connection (18). For this purpose, an elastically deformable latching body (14) engages in a recess (16) of the housing (17). The operational position of the nozzle body (13) is thereby defined with high accuracy, with the result that an undesirable escape of the liquid between the nozzle body (13) and the housing (17) is prevented. Furthermore, at the same time the contact surface can be reduced here to a section (20) which is inclined toward an outlet opening (19) of the fluidic nozzle (12) and has a correspondingly improved sealing.
