Title: Centrally controlled telephone systems with master exchanges and terminal exchanges (central signalling channel)
Inventor: VALENTIN HEINZ ING GRAD
IPC: H04Q11/04
Filed: 1982-03-05
Abstract: The invention relates to centrally controlled telephone systems with a central signalling channel and trunk lines, in particular dedicated telephone systems, with subscriber sets and/or line sets for analog and/or digital information transmission, where the subscriber sets and/or line sets can be interconnected via central switching stages. In the master exchange (HAL), part of the line group (LTGx) is removed and operated in the terminal exchange (EAL) as a system-configuration-individual line group (RLTGm). Both line groups (LTG, RLTG) in each case have dedicated group control devices (GP) which communicate with the central control device (CP) of the main exchange. The speech information can be transmitted via the trunk lines (FL...) and the control information via the central signalling channels (ZZK...). System configurations of this type are implemented in private dedicated telephone networks. <IMAGE>

Title: Coupling device with a variable coupling factor for a superconducting cavity resonator
Inventor: KRAUSE NORBERT DR
IPC: H01P5/04
Filed: 1982-03-10
Abstract: By means of the coupling device with a variable coupling factor, a superconducting cavity resonator is coupled in a vacuum-tight manner to an RF generator or an RF test set via a rectangular waveguide which transmits the RF power of wavelength  lambda . The rectangular waveguide is in this case connected to a coaxial system, which is arranged at right angles with respect to it and contains a metal bellows, terminated by an end plate, and in which a coupling pin is arranged concentrically which is attached to the end plate and projects into the beam tube of the resonator. In the case of this coupling device, it is intended to reduce the coupling losses, which are dependent on the axial position of the coupling pin and on the expansion of the metal bellows. For this purpose, the invention provides for a multi-stage  lambda /4 transformer (27) to be provided in the coaxial system (2) between the metal bellows (13) and the connection point of the rectangular waveguide (15), the mutually adjacent stages of which transformer are formed from hollow-cylindrical line pieces (28 to 30) of approximately the same axial length  lambda /4 and with a different internal diameter (d;D). An end (19) of the rectangular waveguide (15) projecting out of the coaxial system (2) can advantageously be terminated by a short-circuiting slide device (20) whose distance (a) from the axis (10) of the coupling pin (14) is adjustable. <IMAGE>

Title: Arrangement for determining a capacitor which is installed with the wrong polarity in an electrical circuit, for example an electrolytic capacitor
Inventor: WELZHOFER KLAUS
IPC: G01R31/01
Filed: 1982-04-07
Abstract: Polarised capacitors, for example electrolytic capacitors, must be checked to see whether they have been installed with the correct polarity in electrical circuits. For this purpose, a test cup (22) of conductive material is placed over the capacitor (14) to be tested. The test cup (22) is supplied with charging pulses (28) which lead to a charging-up of the capacitor (14) if it is installed with the wrong polarity. If, in contrast, the capacitor is installed with the correct polarity, a fixed potential (0 volt) is applied to the outside of the capacitor and it is not possible to charge the capacitor via the test cup (22). The voltage occurring across the capacitor (14) is supplied to a comparator (38) via an electrometer amplifier (36). The comparator (38) outputs a signal when the voltage across the capacitor (14) exceeds a predetermined voltage. <IMAGE>

Title: Connection lines for transformers
Inventor: MANZINGER ERNST ING GRAD
IPC: H01F29/02
Filed: 1982-04-15
Abstract: These connection lines are used for connecting the windings and winding parts to one another and to bushings and step-switching devices and are subjected to high mechanical stresses, especially as a result of current forces. According to the invention, the connection lines (1) are represented by solid, metallic strips, of rectangular cross-section, and, for guidance and spacing, the strips are located with their edges in grooves in insulating material plates (3) together with which they form a type of double T-profile. Connection lines of such a design are expediently used in large transformers since, in this case, they permit a very versatile structure of the framework for the active part of the transformer, with respect to selection of the distances between the supports (2). <IMAGE>

Title: Three-stroke gas engine with the arrangement principle of its associated auxiliary units
Inventor: BECHT WERNER
IPC: F02B75/02
Filed: 1982-04-17
Abstract: The invention relates to a newly developed internal combustion engine which is driven by means of highly explosive gases such as hydrogen or acetylene. The three-stroke gas engine comprises a stator (S) and an axially supported rotor (R; Fig 3). It is supplied with air and hydrogen by way of an external compressor. The highly explosive hydrogen-air mixture passes through separate ducts of the stator and rotor into a combustion chamber. The very high gas pressure produced by the combustion of the gas mixture directly drives the axially supported rotor. Four pistons in the rotor, which run parallel to the rotor axis, ensure that no fall in pressure occurs inside the ducts lying in the stator and rotor. By means of the associated auxiliary units the three-stroke gas engine can be switched off and started at any time without any difficulty at low energy cost by the use of the highly explosive gas mixture and the external compression. In addition the three-stroke gas engine has an energy recovery system which converts the mechanical braking energy into usable fuel. <IMAGE>

Title: Method for machining comminuted material
Inventor: GOTTERBARM ULRICH
IPC: C10L5/44
Filed: 1982-11-06
Abstract: According to a method for machining comminuted material, which is to be comminuted, for instance, by means of mulching devices, the material is fed to a cutting mill which is provided with specially developed knives which are driven in rotation and interact with a mating knife. The disc-shaped knife or a knife shaft formed from it namely has conveying tines as well as pressing tines which are formed in the outside diameter set back with respect to the conveying tines and closely surrounded by the housing in a partial region of the same. By means of the short pressing tines, the comminuted material is rubbed, upon processing, along the housing so that the drive energy fed to the knife is partially converted into heat and temperatures of 100 DEG C-170 DEG C are reached in the housing. In front of the mating knife, the material is compressed and continuously pressed into a conveyor shaft. As a result of the strong heating, parts of the comminuted material are liquefied for a short time or lignin emerges from wood, so that compacting into a briquette strand, which has a high strength and a high compacting, can be effected.

Title: Device for the remotely-controllable lifting of the valve rod of an overflow or safety valve
Inventor: COURA HERBERT
IPC: F16K17/04
Filed: 1982-11-23
Abstract: The invention relates to a device for the remotely-controllable lifting of the valve rod of an overflow or safety valve, especially for such valves in systems which can be cleaned automatically and are used in the food and drinks industry. As a result of the invention, it is possible to arrange a remotely-controllable lifting device for the valve rod of the abovementioned valves in a space-saving manner in the spring housing or in its axial extension in such a manner that, in consequence, the opening and closing behaviour of the overflow or safety valve is not adversely affected or changed. These advantages are achieved, inter alia, by providing a pneumatically operable piston which is arranged and guided within the spring housing or a drive housing, by the piston, in its quiescent position, enclosing the valve rod in such a manner that the latter remains, by means of the said piston, free of force influence in every possible position, and by the piston lifting the valve rod out of its closed position in a positively-locking manner, after part of its stroke. <IMAGE>

Title: Pump for conveying highly corrosive media
Inventor: KRAEMER ROLAND DR
IPC: F04D29/02
Filed: 1982-11-25
Abstract: A motor pump unit (1) (fig 1) has for protection against highly corrosive conveying media in the region of the pump (2) an inner covering of polytetrafluoroethylene (PTFE). In the case of the motor, different corrosion-resistant materials are used, matched to the different requirements for on the one hand the can (10) and on the other hand for the rotor (9). The can (10) expediently consists of PTFE with a filler content of 10 to 15 % carbon graphite. This produces not only the resistance to corrosive media but also a high mechanical stability and a good thermal conductivity. The rotor (9) with shaft has an enamel casing (11), which has a sufficiently good thermal conductivity and also allows the surface of the rotor to be produced with high fitting and dimensional accuracy. In addition, favourable temperature expansion characteristics are obtained. The application of a continuous impervious enamel layer is assisted by using a solid-iron rotor. In the region of the end windings (21), a casting compound is introduced, preferably of epoxy resin with quartz flour as filler to improve the thermal conductivity and for mechanical support of the can. The bearings are designed as corrosion-resistant sliding bearings. <IMAGE>

Title: Device for indicating an angle of rotation of rotor blades and/or guide vanes on hydrodynamic machines
Inventor: OERTEL RUDOLF DIPL ING
IPC: F04D29/36
Filed: 1983-05-19
Abstract: For the adjustment of rotor blades and guide vanes on hydrodynamic machines, for example screw pumps, it is necessary to provide a device for monitoring the angle of adjustment above floor level. For this purpose, a hydraulic piston is connected to the adjustment mechanism, the said piston being guided in a fixed hydraulic cylinder. A motor drives first and second hydraulic pumps operating on the positive-displacement principle which feed oil from the reservoir to one or the other half of the hydraulic cylinder. The motor is coupled to a revolution counter which makes it possible to indicate the quantity of oil circulated, from which it is possible to determine the travel of the hydraulic piston and hence the angle of rotation of the blades/vanes. The two hydraulic pumps can be replaced by a single hydraulic pump which does not need to operate on the positive-displacement principle and in the circuit of which there is installed a flow meter, it thereby being possible to determine the rotation of the blades/vanes above floor level by means of the quantity of oil circulated. The invention can be used for adjusting rotor blades or guide vanes in the case of hydraulic adjustment.
