Title: Discontinuously operating pneumatic bulk material conveying apparatus for feeding more than one delivery point by means of a common pipe
Inventor: LESK ADOLF
IPC: B65G43/08
Filed: 1981-01-31
Abstract: The apparatus makes it possible to charge several delivery points at the same time by means of a pneumatic suction conveying system. In this arrangement the first vessel viewed in the conveying direction is filled first, then the second and so on until the level indicator in the last vessel indicates that all vessels have been filled. When the subatmospheric pressure in the vessels is eliminated when the conveying fan is switched off, the resilient discharge hose under each vessel opens and the material to be conveyed can be discharged from all the vessels at the same time. In the case of bulk materials which do not run off easily, a pinch valve is arranged under each vessel. When conveying is complete, the runouts of the vessels are opened by venting all the pinch valves. When the vessels have been emptied, a new conveying cycle can be initiated. <IMAGE>
Patent DE-3103471-A1 (DE)
Title: Arrangement for cleaning river courses, canals or the like
Inventor: MUENSTER WALTER
IPC: E02B8/02
Filed: 1981-02-02
Abstract: The invention relates to an arrangement for cleaning river courses, canals or the like, in particular of coarse contaminants, by means of gratings or racks arranged in the river course or canal as well as by means of rack-cleaning devices in operative connection with them. It has been found that, in sewage pumping stations which only have the task of pumping water from one station to the next and of finally feeding it to a treatment plant, floating debris is separated to an excessive degree by the known rack constructions. This is because the fine portions of floating debris are only to be caught in the treatment plant, since they are of great importance for the treatment operation. To achieve this aim, the grating or rack bars are to be designed as rows of short bars attached at a distance one behind the other and having passages in between. The short bars are to preferably have a trapezoidal cross-section, the narrow side of the trapezium being directed against the flow direction of the river or canal.

Title: Method for potential-isolated pulse transmission
Inventor: VOGEL DETLEV DIPL ING
IPC: H03K5/00
Filed: 1981-07-02
Abstract: In a potential-isolated pulse transmission with a magnetic-core transformer between DC-isolated open-loop or closed-loop control devices, the backwards transmission of a signal becomes possible without significant additional outlay if logic stages are provided which, with the aid of the transmitting pulse, generate an acknowledgement pulse which is then supplied back to evaluating electronics in dependence on the signal to be transmitted back via the same magnetic-core transformer. If the signal to be transmitted back is a measurement-value signal, it can be used for changing the amplitude and/or the polarity of the acknowledgement pulse. If a digital signal, for example an error signal is to be transmitted back, this can be done by inhibiting or enabling the acknowledgement pulse.
