Title: Method and device for controlling a pumping station
Inventor: SENG FRANZ
IPC: F04B49/025
Filed: 1983-08-12
Abstract: The invention relates to a method and a device for controlling a pumping station having a plurality of pumps conveying into a container via a common pipeline, the inflow to the container taking place via a plurality of float valves which respond to different liquid levels, and the individual pumps automatically switching off or on as a function of the volumetric flow measured by a flow meter. In order to give the flow meter, which in the case of slight changes in the volumetric flow does not usually respond with adequate reliability, an amplified, i.e. reliable signal, it is proposed according to the invention that when a prescribed liquid level is reached in the container not only the float valve set to this liquid level is actuated , but also the float valve following in the direction of the instantaneous change in the liquid level is actuated for at least a period sufficing to measure the changed volumetric flow.

Patent DE-3343921-A1 (DE)
Title: Process and equipment for recovering the waste heat from molten metallurgical slags
Inventor: FINK FERDINAND DIPL ING DR MON
IPC: F22B1/04
Filed: 1983-12-05
Abstract: This invention simplifies the recovery of sensible heat of metallurgical slags, by transferring the heat by means of rotary pipe coolers to air which can be utilised in waste heat boilers. As Figure 1 shows, the molten slag 4 is charged to the rotary pipe cooler 1 operated in co-current with air 7. The hot lumpy slag 5 leaves this cooler and enters the rotary pipe cooler 2 which is operated with air 9 in counter-current and which it leaves as cold lumpy slag 6. Hot air 8 and 10 combined 11 are utilised in the waste heat boiler 3 to give steam 12. The fans 14, 15 and 16 regulate the air rates and the pressure conditions of this process. This invention recovers the waste heat from molten slags in the simplest manner at high efficiency and is capable of controlling the glassy fraction/crystalline fraction ratio in the discharged slag within a wide limit, so that the slag becomes a useable building material. The environment is not polluted, no hydrogen sulphide is formed, no effluent is left behind and no dust escapes. <IMAGE>

Title: Steel sheet piling for bank stabilisation
Inventor: LUDEWIG ERNST GUENTER DIPL ING
IPC: E02D5/04
Filed: 1984-02-03
Abstract: The steel sheet piling for bank stabilisation is formed by two piles 1 which are firmly anchored in the ground and between which aprons 3 of flat steel sections are hung in the form of a garland. The piles have a rectangular cross-section of appropriate steel sheets. The anchoring is effected from their interior by tie rods known per se. The aprons 3 of flat steel section are stressed in tension and need not be passed down into the load-bearing subsoil. It is also possible, without additional measures, for them to end below the water surface in accordance with the environmental requirements. A considerable weight and cost saving is made through this measure. <IMAGE>
Patent DE-3405147-A1 (DE)
Title: Jack
Inventor: VITT HEINZ-GEORG
IPC: B62B5/00
Filed: 1984-02-14
Abstract: The invention is based on a jack with a lever which can be swivelled upwards by means of a shaft, receives loads and is mounted on a chassis. In order to be able to use these jacks even when the material to be transported projects beyond the sides of the rolling plate or the like to which the jack has to be attached, on the basis of the invention the shaft is not connected to the lever directly but rather indirectly via a horizontal pulling rod, the shaft also having a separate running gear which is connected to the roller running gear of the lever with spacing.
Patent DE-3406967-A1 (DE)
Title: Line-tensioning toggle
Inventor: ESFELD SIEGFRIED DIPL ING
IPC: F16G11/12
Filed: 1984-02-25
Abstract: A toggle for line-tensioning consists of a flat bar which carries laterally at one end two hooks which are angled so as to diverge at right angles parallel to the bar axis and onto which the line is wound. At the other end of the bar, there is a hook which is angled at right angles transversely to the bar axis and which is hooked under the line. A torque is exerted on the tensioning toggle by the line tension, presses the hook against the line and thus prevents unintentional release. The line-tensioning toggle can be attached at any point of an already fastened line and be actuated without further aids.

IPC: B65G47/52
Filed: 1985-03-28
Abstract: An apparatus used to bridge the gap between two consecutive conveyor belts (8 and 9) consists of a belt band (1) which is guided over deflection rollers (2 and 3). Since the ratio of the diameter of the deflection rollers (2 and 3) to the diameter of the deflection rollers (6 and 7) of the conveyor belts (8 and 9 respectively) is at least 1:8 to 1:12, the deflection rollers (3 and 4) can be so arranged, relative to the deflection rollers (6 and 7 respectively), that a gore of minimum size is formed between the deflection rollers (2 and 3 respectively) and the deflection rollers (6 and 7 respectively). The belt band (1) and the conveyor belts (8 and 9) can rotate with, in each case, one strand in an identical plane and guarantee a virtually continuous bridging from the conveyor belt (8) to the conveyor belt (9). <IMAGE>

Title: Munition article having an ejectable carriage
Inventor: FUERST WILHELM DIPL ING
IPC: F42C15/20
Filed: 1985-05-03
Abstract: In the case of a munition article (1) having a carriage (4) for displacement of functional elements of its detonation safety or detonation triggering device from a retracted position, during the phase of movement into a function position, which is displaced beyond the outer jacket surface (7) of the munition article (1), it is intended to ensure, while maintaining easy motion during displacement, a functional position which is defined by virtue of the design with respect to the orientation of the munition longitudinal axis (2). For this purpose, the carriage (4) is inserted into a carriage guide (8), which is profiled in an n-shape, and leaf springs (10) press its rearward bearing surface (13) against the yoke region (18) of the carriage guide (8), in a force-fitting manner. For this purpose, the projecting spring ends (14) of the leaf springs (10) which are mounted on the carriage (4) transversely with respect to its longitudinal axis engage in longitudinally running recesses (15) on the inner jacket surface of the longitudinal walls (16) of the carriage guide (8). The elastic support of a locking bolt (19) in a carriage guide longitudinal wall (17) can at the same time be used for force-fitting bearing of the carriage (4) on the opposite longitudinal wall (16), for defined orientation of the carriage (4) transversely with respect to the carriage guide yoke region (18). <IMAGE>

Title: Cooling fan with a controlled hydraulic coupling for an internal combustion engine
Inventor: PETSCHICK SIEGFRIED
IPC: F04D25/02
Filed: 1985-09-07
Abstract: The invention relates to a cooling fan (1) for an internal combustion engine, especially a diesel internal combustion engine. The cooling fan has a controlled hydraulic clutch (2), the primary part (5) of which is driven by the internal combustion engine and the secondary part (6) of which is connected to the impeller (3) of the cooling fan (1). The hydraulic supply to the coupling (2) is controlled by a control circuit for adjustment of the fan speed as a function of operating parameters (23). Since hydraulic couplings are not completely drained, a drive torque is always imparted to the secondary part, so that the fan impeller (3) always rotates at a minimum speed. In order to obtain a zero fan speed, it is proposed according to the invention that the secondary part be connectable by way of a brake (36), releasable as a function of its speed, to a rotationally fixed housing part (39) of the cooling fan housing (20, 31) (fig. 1). <IMAGE>
