Title: Measuring fuel consumption in IC engines - uses difference in digital flow signals of feed-return lines
Inventor: SCHLEUPEN RICHARD DIPL ING
IPC: G01F9/00
Filed: 1980-11-04
Abstract: An arrangement for measuring the fuel consumption of an internal combustion engine forms the difference of signals for flowmeters in the fuel feed (12) and return (15) pipes. The difference signal is formed in a purely digital manner. This results in very accurate measurements and good ageing resistances. The flow measurement values (f1,f2) are fed in digital form to the clock input and the control input of a bistable switching stage (17). The output signal senes (f3) of the bistable switching stage is evaluated by using a frequency measurement device. The bistable switching element may be in the form of a D-flipflop. The circuit arrangement is very economical. The use of digital flow measurement (14,16) devices precludes the need to convert their output signals before evaluating them.

Title: Process and arrangement for carburizing the edge layers of metallic workpieces
Inventor: PLANK FRITZ ANDREAS
IPC: C23C8/22
Filed: 1981-03-18
Abstract: In a process with an arrangement for carburizing the edge layers of metallic workpieces at reduced pressure by a carburizing gas, which serves as the carbon carrier, for the purpose of surface-hardening, the workpieces are heated in a furnace to carburizing temperature, while the carburizing gas flows round them. In a box furnace (batch furnace) shown and described as an example, this involves injecting endothermic gas as the carburizing gas in constant circulation and, as known per se, with at least the speed of sound into the furnace chamber and drawing it off again from the furnace chamber, while maintaining a reduced pressure, the furnace atmosphere - as known per se - being continuously analysed and, if required, enrichment gas being admixed to the endothermic gas circulation.

Patent DE-3113309-A1 (DE)
Title: Galvanic element
Inventor: KUEHL THOMAS DIPL ING DR
IPC: H01M50/171
Filed: 1981-04-02
Abstract: A galvanic element of the button cell type is protected more effectively against leakage of electrolyte by that part of the two components (2, 3) of its metal casing which are of opposite polarity and electrically insulated against one another, which is of negative polarity (3) being enamelled in the region of the sealing zone. In this arrangement, the enamel coating (1) may function on its own as a seal or may be compression-bonded to a conventional plastic seal (4). The enamel particularly inhibits the creepage of alkali, which occurs to a greater extent on negative output conductor bushings for electrochemical reasons, by keeping, as an insulator, the boundary zone enamel-sealing plastic free of the potential of the base metal, as well as, owing to its strong chemical bond to the base metal, precluding a transmigration of liquid even in this boundary region. <IMAGE>

Title: Tamping device for coking plants, and process for compacting coking coal
Inventor: WEBER HEINRICH DR
IPC: C10B37/04
Filed: 1981-11-14
Abstract: In the coking of coals or coal mixtures of poor coking ability, the compaction is achieved by means of tampers, whose tamper rods can be activated via shakers or are parts of a shaker. The plate of the tamper bottoms is of split design and can be tilted downwards, so that, with discontinuous replenishing of the coal mixture, the two parts of the tamper bottoms are tilted away downwards by pulling up the tamper rods, so that they do not impede the flow of coal. In addition to the discontinuous process for compacting coking coal, a continuous process is also proposed in which, during the compaction of the coal mixture, new coal is continuously filled in, preferably as a thinly flowing feed stream. <IMAGE>

Title: Protective device for hollow profiles to be bent using a formable filler
Inventor: FISCHER WILLY GERD
IPC: B21D9/15
Filed: 1981-12-05
Abstract: The invention relates to a protective device for hollow profiles to be bent using a formable filler. Devices of this kind are used in pipes to be used for carrying fluids under pressure to prevent deposition of the filler on the internal surface of the pipe. In the case of thin-walled pipes with a small bending radius and diameter, such as those used, for example, in aircraft and machine construction, a protective film between the filler and the internal surface of the pipe is used as the protective device. When emptying and cleaning the bent pipe, parts of the protective film which remain stuck in the pipe and any filler particles which have penetrated can only be removed by further expenditure in terms of work and costs. In order to guarantee complete removal of the protective device and filler particles without increased expenditure, a filler-independent, flexible, thin-walled tubular sleeve (2), the ends of which project beyond the ends of the pipe, is introduced into the pipe (1) to be bent. During the filling and compression or deformation of the filler (3), this tubular sleeve is pressed against the internal surface of the pipe and, after the bending operation has been performed and compression removed, is pulled out of the bent pipe together with the filler in it. <IMAGE>
