Title: Testing computer program stored in read=only memory - transferring data into read-write memory during program run to enable check of testing completeness
Inventor: HELMSTAEDTER GERALD
IPC: G06F11/36
Filed: 1990-07-30
Abstract: Testing a computer program stored in memory (2) and readable from the memory by a central processing unit (CPU) while the program is running, involves filling a read-write memory (6) with predefined data before the program is run. When the program is run the read/write memory is switched to write mode, and the same addresses are fed to it as to the program memory whilst a second set of predefined data is also fed to the read/write memory. When the program has been run the read/write memory is checked to determine whether the second data set has been entered for all addresses provided for the program.

Title: Turbine type air sifter - has sifting action enhanced by suction at inside edge of rotor vanes
Inventor: LESCHONSKI KURT PROF DR ING
IPC: B07B7/083

Patent DE-4123464-A1 (DE)
Inventor: HUEBSER KARL DIPL ING
IPC: B22D47/00
Filed: 1991-07-16
Abstract: The invention relates to a process for operating a die-casting machine in which the molten metal (6) in a reservoir (7) is taken in metered quantities via a suction or rising pipe (8) into a filling chamber (9) and from there pressed via a die-casting ram (14) into a hollow mould (5) shaped in accordance with the workpiece to be produced. Here, after a predeterminable number of casting cycles, and preferably after each cycle, the suction or rising pipe (8) is detached from the filling chamber (9), whereafter the molten metal filling aperture (25) is cleaned and the filling chamber (9) and hollow mould (5) are rinsed with gas to clean them and/or coat them with a parting compound via means (15) in the region of a molten metal filler aperture (25) in the filling chamber (9). These cyclic cleaning processes greatly reduce the risk of impurities in the molten metal which lower the quality and further machining properties of the finished workpiece.
