Patent DE-3709776-A1 (DE)
Title: Method of measuring the flow of a medium through a pipeline or the like
Inventor: BRECKNER KURT DIPL ING
IPC: G01F1/36
Filed: 1987-03-25
Abstract: In known methods, the medium in the pipeline has a defined flow direction. For measuring the flow in mutually opposite flow directions of the medium, different pipeline systems are necessary. The new method is, however, intended to make possible a flow measurement which can be implemented simply and with low outlay. According to the new method, the medium can be conducted in both directions through the pipeline and the flow and the direction of flow of the medium can be derived from the pressure difference detected. The method can be used in systems in which the procurement from outside and the delivery of the medium are carried out via the same pipeline.
Patent DE-3710261-A1 (DE)
Title: Method of operating a compressor
Inventor: ZOLLDANN WOLF
IPC: F04B49/02
Filed: 1987-03-28
Abstract: Method of operating a compressor, in which the suction opening is throttled in idle running and the full suction cross-section is made available by opening a valve. In valves, in which the closing pressure is exerted by an immanently firmly predetermined closing force and the force necessary for opening is defined by the level of the pressure in the compressor pressure space, the closing force is designed always to be as small as possible and defined only by being just sufficient to close the valve. On starting the compressor, this leads to the pressure build-up in the compressor taking place very quickly. It is true that on the one hand this is in general required, but it has, in particular in the case of screw compressors, the disadvantage that the screws are under high pressure while the oil lubrication is not yet optimum. In order to make possible longer starting with a pressure build-up which first rises slowly, the closing pressure is raised so high that opening of the valve can take place only after reaching a pressure in the compressor pressure space of 2 bar.

Patent DE-3725315-A1 (DE)
Title: Circuit arrangement for an electronic exchange line holding coil in an exchange junction circuit of a telephone private branch exchange having dialling control which emits pulses
Inventor: ALTENDORFER ALOIS
IPC: H04M7/00
Filed: 1987-07-30
Abstract: An electronic coil arrangement is used in the exchange junction circuit for an exchange line which is terminated by a transformer which is decoupled from the line in DC terms. In order to enable the loop current flow, an electronic switch (which may be, for example, a Darlington-pair stage or a field-effect transistor) is arranged in a transverse branch with respect to the line wires. The switching path of an optocoupler (02) is connected in the drive circuit of said switch, that connection point (A) of which optocoupler (02) which is remote from the drive electrode of the electronic switch is coupled via an energy store (C) to one line wire (b) and via a resistor (R7) and the switching path of a further optocoupler to the other line wire (a). These optocouplers are controlled on the basis of control pulses which are supplied from the control unit, which carries out the connection processes, on the basis of the subscriber behaviour. Apart from the dialling pulse emission, the arrangement acts as a coil having a high impedance and a low insertion loss. The energy store (C), which forms a low-pass filter with the said resistor (R7), is used during pulse transmission to ensure that the electronic switch opens and closes the line loop in accordance with the control pulses applied to the optocoupler, virtually without any pulse loop. The arrangement thus at the same time carries out the function of the otherwise normal pulse contact. <IMAGE>
Patent DE-3728609-A1 (DE)
Title: Device for spin-dryer (centrifuge) starting current limiting and for preventing uncontrolled operating states in the event of power failures, especially in the case of washing machines
Inventor: WIPPERFUERTH FRANZ-JOSEF ING G
IPC: D06F34/08
Filed: 1987-08-27
Abstract: If the mains voltage fails during operation of a spin dryer, the washing drum can stop. The washing falls to the base of the drum and is no longer uniformly distributed. When the power returns, the machine accelerates to the full rated spin dryer rotation speed. In this case, washing unbalances occur which lead to damage to the machine. In order to prevent this, a small contactor is mounted on the washing liquid container, adds an additional field winding as a result of mechanical movements, and changes the drive motor from an initially high rotation speed to a lower rotation speed. The new circuit uses rotation speed electronics to identify the actual value of the drum rotation speed, switches over the field winding and at the same time limits the spin-dryer starting current. The actual value (11) of the drum rotation speed is logically combined with the field winding changeover. Depending on the actual value (11) of the drum rotation speed, either the field winding is tapped via the controller (5) or the full field winding (2), (3) is connected, via the controller (6), in order to reduce the rotation speed. The new circuit is suitable for use in domestic washing machines. <IMAGE>
