Title: Liquid or gas pressure regulating system - uses measurement of power absorbed by compressor motor to indicate instantaneous pressure of fluid
IPC: F04B49/06
Filed: 1978-01-16
Abstract: The system is designed to regulate non atmospheric pressures which are created or maintained by at least a motor (7) driven pump (3). The system has a device for controlling the pumps motor, and a circuit which automatically measures the load (absorbed power) of the pump motor during its operation. The load measurement is used for indirect measurement of the instantaneous pressure state in a pressure container (1).

Title: Bistable relay control circuit - switches to deactivated state when excitation voltage is removed, with semiconductor switch short-circuiting excitation coil capacitor
Inventor: SAUER HANS
IPC: H01H47/22
Filed: 1978-10-23
Abstract: The bistable relays (RIs) excitation coil is in series with a capacitor (C1). The relay is excited to an energised state and the capacitor charged simultaneously. The series circuit is short-circuited in absence of excitation voltage through a semiconductor switch (T1). The semiconductor switches output circuit is in parallel with the coil and capacitor and in parallel with a resistance (D1) which is in series with the coil and capacitor. When the capacitor is fully charged and the excitation voltage switched off, a voltage drop appears across the resistance. This makes the semiconductor switch conductive, so short-circuiting the series circuit. The relay switches back to its original de-energised state.
