Title: Vacuum hysteresis switch operated by pressure medium - has additional contact signalling fault when pressure is outside hysteresis pressure values
Inventor: FEGER ROLF ING GRAD
IPC: H01H35/26
Filed: 1977-05-10
Abstract: The pressure operated vacuum hysteresis switch has a snap-action contact mounted on a diaphragm. This contact closes a circuit through fixed contacts projecting into the switching chamber, at a certain pressure of the medium, and breaks the circuit at a different pressure. The diaphragm also operates a bridge contact (17) which makes a connection between at least one of the fixed contacts (27, 28) and a fault signalling contact at a limit pressure outside the pressures determining the switch hysteresis. The contact bridge may connect both fixed contacts and the fault signalling contact together.

Title: Combination electromagnet and permanent magnet separator - has non-magnetic drum housing magnet assembly to hold ferrous materials for separate discharge
Inventor: FOGLE ROBERT
IPC: B03C1/14
Filed: 1977-08-02

Patent DE-2750626-A1 (DE)
Title: Lime admixture to sewage - with radial water jets in downstream mixing pipe length
Inventor: HRUSCHKA HERBERT DIPL ING
IPC: B01J8/00
Filed: 1977-11-11
Abstract: Lime is added in the form of powder to sewage in an open channel at a point which is followed by a mixing stretch. The mixing stretch includes an enclosed pipe below the lowest possible water level in the channel. Nozzles which are arranged in the pipe are connected to a pump for the injection of additional water from a reclarification basin. This ensures that the lime is suspended in the sewage in extremely fine distribution and is fully dissolved. No moving parts are exposed to the abrasive action of a lime suspension and the power costs for paddle mixers have been saved.

Title: Escape route indicating system - has elements capable of transmitting or converting signals with three different logic values
Inventor: KAWAMURA MASANORI
IPC: A62B3/00
Filed: 1977-12-09
Abstract: The escape route signalling system is operated by signals from fire alarm fittings connected to the wiring of the corridor system. In case of fire the installation indicates the escape route towards the possible fire exits. The system consists of fire alarm operated circuits which feed signals to a central unit. The signal transmitter distributes a signal to other points of the system. The system contains signal converters fitted in the vicinity of fire alarm fittings. The converters are controlled by the fire alarm fittings in such a manner that in case of fire, a change of signal is produced at the location of the converter. The system is fitted with escape route indicating installation designed in such a way that an escape direction in dependence of the signal incoming direction through the wiring is produced.

Title: Discharge valve of concrete pump - has variable axial force exerted on it to allow freedom of movement between strokes
Inventor: RIPAMONTI EUGENIO
IPC: F04B7/00
Filed: 1978-08-14
Abstract: The pump has two parallel cylinders (2) in which pistons (3) draw concrete from a hopper and discharge it through an S shaped discharge piece (4) into the delivery pipe (5).

Title: Synchronising circuit aligning receiver to ternary coder - determines frequency at which tempering control signals exceed reference level
Inventor: HEMSWORTH ALAN DENTON
IPC: H04L25/49
Filed: 1979-03-30
Abstract: A synchronization circuit which lines up a receiver in a digital transmission system to incoming redundant ternary code signals. It consists of steps for determining the ternary code words, as identified by the receiver, in accordance with its tempering control signals. It involves determining the number of times the tempering control signals exceed a previously determined number. The various ternary code phases contain forbidden code words and the tempering control signals are shifted in order to align the receiver with the ternary code phase containing the minimum of forbidden ternary code words.
