Abstract: The invention relates to a plug-in connection provided with an angle-locking device for connecting tubular pipes and flexible hoses. The aim of said invention is to improve the design of a said type plug-in connection in such a way that it is possible to produce the angular locking device by particularly simple means, thereby avoiding any risk of an accident during operation of the plug-in connection, and to embodied said connection optionally with or without angular locking device without important transformation expenditures. The inventive connection is, therefore characterised in that it comprises a pipe insertable into internal space of a plug-in part which is provided, on the front-surface side thereof in a plugging.

Abstract: The invention relates to a plug-in connection for pipe and hose lines with a reinforced material cross-section. Said connection consist of a neck that forms at least one detent collar and a connector that can be engaged with the neck and has a least one detent spring with detent limbs, the latter locking behind at least one of the detent collars of the neck. In order for the connector to absorb intense detent forces, it is characterized by at least a double wall in the vicinity of the detent spring openings.

Abstract: The invention relates to a device for the molding of plugs as part of a pipe connection and a method used for the device, wherein the pipe connection is constructed as a sealing plug-in connection with a connecting piece and a plug that can be locked with the connecting piece, wherein the plug exhibits an outer part and an inner part that are connected to each other in a single piece and forms an annular gap on the rear free end. The invention is characterized in that a molding slot is placed in the material of the plug with an expanding tool acting in radial direction, said molding slot engaging in the material of the pipe or hose and that a sensor subject to a radial deformation is arranged in at least one location of the expanding jaw, said sensor recording the radial deformation work of the expanding jaw and regulating the expanding drive with it.

Abstract: An electric motor (1) having a coaxially associated pump (6) for a coolant circuit, in particular in a system with temperature transfer and/or heat transfer, in which a shaft assembly (5) transmits a torque from the electric motor (1) to at least one impeller (8) arranged in the pump housing (7) within housing parts (7, 10) in the form of a hermetically sealed pressure enclosure, and a flywheel (12) is arranged between the electric motor (1) and the pump housing (7). All of the rotating parts are arranged within a hermetically sealed motor/pump unit, and the motor/pump unit is filled with fluid. The flywheel (12) comprises a flywheel body (13) made from a high-strength material having a large number of cavities (16, 17) with inserts (16, 17) formed of or containing a heavy metal having a density greater than 11.0 kg/dm3 arranged in the cavities.

Abstract: The invention is concerned with a plug-type coupling comprising a molded sealing ring for producing liquid-tight or gas-tight connections, said plug-type coupling having a socket and a plug that can be axially plugged into each other, and said molded sealing ring being implemented as a lip seal disposed in a circumferential groove of the plug. The invention has as its object to further develop a plug-type coupling comprising a molded sealing ring of the above type in such a way that a pumping effect is prevented, in order to thus prevent a vacuum on the groove bottom during pulsating stresses on the plug-type coupling.

Abstract: The present invention provides systems and methods for the evaluation of the urethra and periurethral tissues using an MRI coil adapted for insertion into the male, female or pediatric urethra. The MRI coil may be in electrical communication with an interface circuit made up of a tuning-matching circuit, a decoupling circuit and a balun circuit. The interface circuit may also be in electrical communication with a MRI machine. In certain practices, the present invention provides methods for the diagnosis and treatment of conditions involving the urethra and periurethral tissues, including disorders of the female pelvic floor, conditions of the prostate and anomalies of the pediatric pelvis.

Abstract: The invention relates to a compensator modular unit for a multistage pump housing, ensuring as compensation device during hot or cold temperature shocks compensation of changes in length caused by said shocks.

Abstract: A centrifugal pump system for moving hot media includes a pump section, a motor section and mounting elements holding the pump and motor sections together. A force is formed by the mounting elements that is transmitted between the pump section and the motor section. A heat barrier is positioned between the pump section and the motor section. The heat barrier includes an insulating ceramic element. The force transmitted between the pump section and the motor section is transferred through the ceramic element.
