Patent DE-3201896-A1 (DE)
Title: Clamping device
Inventor: MENNEKES WERNE
IPC: E21D11/22
Filed: 1982-01-22
Abstract: The known clamping device for determining the push-in resistance of interlocking channel-section segments of the roadway support system yielding at the periphery consists of a sleeve-like clamping body and a hook bolt passing through the sleeve. With only a single projection in the transverse plane of the hook bolt, the clamping body engages in a point-like manner in a flange fillet. The fillet projection consequently slides skid-like in this flange fillet. The normal forces required for satisfactorily determining the push-in resistance are consequently high. In the design according to the invention, the clamping body is of U-shaped design and has two fillet projections arranged on either side of the hook bolt at a distance from one another in the longitudinal direction of the channel-section segments. The fillet projections and the adjoining end faces of the side walls of the clamping body are accurately adapted to the contours of the channel-section segments. In this way, the clamping body tilts during a relative movement of the channel-section segments, and the preloading force of the hook bolt passing centrally through the clamping body is increased for a specific increase in the push-in resistance. <IMAGE>

Title: Protection circuit for a power transistor
Inventor: KLAUSECKER KARL DIPL ING
IPC: H02H7/20
Filed: 1982-01-26
Abstract: In order to protect a transistor, especially a power FET (LT) against excess currents and excess voltages, a thyristor (Th) or transistor is connected between the gate and source as a protection switch, its control connection (St) being connected to the transistor drain connection via a capacitor (C). In the event of excess voltages, the capacitor supplies a control current for the protection switch, by means of which current the control path of the transistor is short-circuited and the transistor is automatically switched off. The capacitor represents high-impedance isolation between the drain and gate, and the control circuit of the transistor is not loaded by any control power for the protection switch. The circuit can also be used for bipolar power transistors. <IMAGE>

Patent DE-3222307-A1 (DE)
Title: Lattice girder
Inventor: MITTELSTAEDT KLAUS DIPL ING
IPC: E04C3/04
Filed: 1982-06-14
Abstract: The invention relates to a lattice girder, in particular a lightweight lattice girder, having upper and lower booms which are connected to one another via strutting. It is precisely in lightweight lattice girders that the buckling length of each strut in the strutting is often relatively large, so that the buckling strength of the struts is low. The object is to construct a lattice girder of this type in such a way that the buckling length of the struts in the strutting is reduced and hence their buckling strength is increased in a simple manner. This is achieved according to the invention by a tension element running through in the girder longitudinal direction and anchored in a tension-proof manner at both ends, said tension element being supported at the points of intersection with the struts in a force-transmitting manner on the latter.

Patent DE-3236071-A1 (DE)
Title: Device for parallel supply into an AC or three-phase network
Inventor: BRAUN RUEDIGER DIPL ING
IPC: H02J3/38
Filed: 1982-09-29
Abstract: In order to synchronise a final control element (an invertor (2) supplied, for example, from a solar generator (1) or an externally driven synchronous machine) to a network (11) to be supplied, both the magnitudes (¦Uw¦, ¦Un¦) and the directions of the corresponding voltage vectors are determined by means of coordinate converters (21, 31) and vector analysers (22, 32) from the final control element output voltage (Uw) and the network voltage (Un). The difference (¦Un¦-¦Uw¦) of the magnitudes is supplied via a magnitude controller (30) to the amplitude control input (3) of the final control element. A vector rotator (25) forms the angle between the vectors, which angle can be controlled to zero by a phase controller (33) acting on the frequency control input (4) of the final control element (2). In order to keep the final control element in synchronism with the network after closing the synchronising switch (14), and to control the exchange of real power and reactive power at the fundamental frequency between the mains and the final control element, the real component and the reactive component are determined from the measured current value (Iw) by means of a coordinate converter (41) and a vector rotator (42) and are each supplied to a controller (43, 44). The output signal of the real current controller is also connected to the phase controller input, and the output signal of the reactive power controller (43) is additionally connected to the magnitude controller input. This results in a universal apparatus which facilitates both network synchronisation and maintenance of a network-synchronous parallel operation of the final control element, while also facilitating the transition to an externally synchronised supply into a passive consumer network (isolated operation). <IMAGE>

Patent DE-3403132-A1 (DE)
Title: Universal pressurised gas engine
Inventor: MESINA MARIAN DR ING
IPC: F01C1/46
Filed: 1984-01-30
Abstract: The invention relates to a new design of rotary piston engines, which can be driven by the pressurised gas fed in from outside or by fuel combustion. The special characteristics of this engine are movable seal elements incorporated into the stator, the movement of which elements is controlled so that they can evade the oncoming rotor blades at any time. On the other hand these seal elements in their basic position are applied gas-tight against the stator and the body of the rotor so that they prevent the gas flow in the void between stator and the body of the rotor in a tangential direction, counter to the direction of rotation of the rotor and thereby permit the build-up of drive pressure. For a predetermined engine size, the torque and power of the engine can be increased almost proportionally by the number of controllable seal elements and of rotor blades. Temporary fluctuations of the torque and power can thereby also be reduced. In its design, the proposed engine is very simple and very easy to control.

Filed: 1984-02-08
Abstract: Packaging machine (1) with an evacuation and sealing station (3) for welding what is called monofoils (6, 9) with a permanently heatable welding element. In order to prevent the monofoil from being destroyed by contact with the permanently heated welding element, there is provided a control (36) to create inside a chamber a differential pressure between the pressure on top of the upper foil and the pressure under the latter, so that the upper foil, during and after contacting with the welding element (13), remains stretched on the product and the lower foil. It is only after a cooling phase that the difference of pressure is supressed so that the package with the foil then restabilized may be removed and taken away.
