Patent DE-3361901-D1 (DE)
Title: Process for limiting the opening currents of the circuit breakers in a high-voltage switchgear, and application of the process
Inventor: BLAHOUS LEOPOLD DR
IPC: H02H7/28
Filed: 1983-04-07
Granted: 1986-03-06
Abstract: In a high-voltage switching system, nodes (1, 2, . . . , 8) are connected in the form of a ring via switching points (12, 23, . . . , ) which in each case contain a circuit breaker. In this system, the breaking currents of the circuit breakers are to be limited and thus the breaking capacity of the circuit breakers provided in the system is to be reduced if a short-circuited part (for example node 1) is separated from a faultless part of the system. This is achieved by opening a switching point (for example 45) of the nodes connected in the form of a ring, between the contact feeders of which switching point and the non-available node (for example (1) in each case at least one available node (for example 2, 3, 4, 5, 6, 7, 8) is provided, via which a component short circuit is fed into the ring. It is of particular advantage in this case to open that switching point (for example 45) which divides the short circuit current flowing towards the short-circuited part (for example node 1 ) into two approximately equal halves, since then the maximum breaking current in the power-switching points (for example 12, 18) only needs to be half the maximum short circuit current of the high-voltage system.

Title: Re-treatment installation of waste concrete
Inventor: RIKER RUDOLF
IPC: B03B11/00
Filed: 1984-07-10
Granted: 1987-03-05
Abstract: Surplus concrete or return concrete to be processed is poured into a high-capacity receiving bin and is transferred at a metered rate from said bin by means of a screw conveyor to a washing apparatus, in which fine components are separated from very fine components. The transfer at the metered rate is effected in dependence on the driving power of rotary motors of the rotary washing apparatus. When the driving power of the motors exceeds a predetermined value, then the motor of the screw conveyor is deenergized. When the driving power decreases below that value or below another value, the supply at the metered rate is resumed. The plant operates fully automatically and when the receiving bin has been emptied the plant is automatically cleaned and automatically shut down.

Title: An opening arrangement and a method for the manufacture of the same
Inventor: CARLSSON LARS
IPC: B65D77/30
Filed: 1985-03-07
Granted: 1988-10-27
Abstract: Opening arrangements on packing containers are often of the type which comprises a prefabricated pouring opening. The cut edges appearing around the pouring opening must be protected, e.g. for reasons of hygiene, from the liquid contents present in the packing container, and this is generally done by a liquid-tight strip applied to the inside. A simpler manner of achieving this protection consists in ensuring that the thermplastic layers (3, 4), which in general are present on both sides of packing laminate, extend past the cut edge (12) and are sealed in a liquid-tight manner to each other. This can be achieved simplest if the hole- punching of the carrier layer of the material is done prior to the application of the thermoplastic layers.

The cathode is porous and foil-like. The cathode and cation exchanger membrane form the actual cathode chamber filled with catholyte and the cathode and cell wall form a gas space. Water is fed into the cathode chamber and alkali metal hydroxide solution is withdrawn from it, hydrogen is withdrawn from the cathode chamber and gas space, and aqueous alkali metal chloride solution is fed into the anode chamber and gaseous chlorine, together with depleted alkali metal chloride solution, is withdrawn from it. A direct voltage which is at least the same as the decomposition voltage is applied to the cathode and anode. A higher pressure is established in the cathode chamber than in the gas space.
