Title: Method for starting and shutting down a railway converter, using the direct converter which is required for slip supply
Inventor: BECK HANS-PETER DR ING
IPC: H02P1/16
Filed: 1984-03-22
Abstract: In the case of a method for starting and shutting down a railway converter which is used for energy exchange between a three-phase network and a single-phase railway network and consists of a single-phase synchronous machine, a three-phase shaft generator, an excitation converter and an asynchronous machine which is supplied in a duplicated manner and has a direct converter which can be connected on the rotor side, the object exists of synchronising the railway converter to the two networks without any transient oscillations, and of reducing the apparatus complexity. This is achieved in that the asynchronous machine (1) is short-circuited on the stator side, in that the single-phase synchronous machine (6) is accelerated in the lower speed range with the asynchronous machine (1), which is supplied from the direct converter (4), up to a speed at which the torque which can be emitted by the single-phase synchronous machine (6) is greater than that of the asynchronous machine (1), and the direct converter (4) is then disconnected from the rotor windings of the asynchronous machine (I, II, u1...w2) by means of switches (S21, S211, S22, S221), and is coupled to the stator winding (61) of the synchronous machine (6) by means of further switches (S71, S711, S72, S721), and in that the asynchronous machine is accelerated up to the rated speed with the synchronous machine, which is supplied via the direct converter. <IMAGE>

Patent DE-3420472-A1 (DE)
Title: Cleaning valve
Inventor: LUBS WOLFGANG
IPC: F16L45/00
Filed: 1984-06-01
Abstract: When a heating device or a boiler is to be cleaned from inside, it has to date been necessary to call in an expert. The latter has to open the boiler system at the inlet and outlet. One end of the heating coil is connected to a pump, and from there a cleaning agent is pumped in which runs through the system and flows back once again at the other end into the pump container. The cleaning valve eliminates this expenditure, and it is possible to carry out cleaning in a kinder fashion and more frequently by attaching to the cleaning valve in a manner capable of use by any layman a vessel (compression or pressure vessel), said valve being opened thereby and the cleaning agent thus being able to flow in. All that is required is to turn off the municipal water tap (which is mounted in front of each device) and to open the system via the next water tap in order that the solvent can be pressed into the heating coil. After a waiting time, the municipal water tap is re-opened and flushing is allowed for a certain time. This type of cleaning is more cost-effective and kinder to the device, since it is possible to clean the device more frequently and in a gentler fashion.

Patent DE-3508726-A1 (DE)
Title: Free piston engine
Inventor: WILHELM KURT
IPC: F01B11/00
Filed: 1985-03-12
Abstract: In order to improve the running reliability the two cylinder heads of the double acting free piston engine connected to one another are axially movable in the engine block and drive the power output devices, which can be switched on and off and locked as a function of the load, and which are preferably piston pumps or compressors. The engine piston oscillates free of mechanical coupling and direct power output. It transmits its excess kinetic energy by way of the respective pressure in the two working chambers of the engine to the movable cylinder heads. This variable coupling between the power output devices and the engine pistons contains a system-dependent automatic control of the power output, the control characteristic of which can be adapted by influencing elements to the changing operating conditions.
