Title: Appts. for extinguishing borehole fires in oil deposits - includes sliding carriage pushed over borehole so that aperture in carriage bottom takes oil outflow for direct piping away
Inventor: SAAM JOSEF
IPC: E21B33/02
Filed: 1991-05-06
Abstract: Appts. has a sliding carriage resistant to fire and heat. The carriage has a flat sliding bottom surface from which an opening (1) leads into the carriage interior and directly from there into a pipe (10) that leads away from the carriage (2). Pref. the forward end of the carriage is at an angle to the sliding bottom surface.

Title: Sheet metal cutting tool - has one jaw with attached platform which prevents metal from bending when being cut
Inventor: BECK GUENTHER
IPC: B23D29/02
Filed: 1991-10-01

Patent DE-4209967-A1 (DE)
Inventor: EYERMANN MANFRED
IPC: H01H50/46
Filed: 1992-03-27
Abstract: A solenoid switch for a starting device of an internal combustion engine provides damping of the pull-in movement of an armature (13) so as to increase reliability at high temperatures and reduce the influence of production tolerances. For this purpose, a metal ring (27), through which the magnetic flux of the solenoid winding (12) passes, is permanently arranged in the area of the solenoid winding (12) and is dimensioned in such a manner that when the armature (13) is attracted, damping forces occur due to eddy currents in this metal ring (27) which prevent a bouncing of the contacts (17, 23) of the solenoid switch. <IMAGE>

Patent DE-4219643-A1 (DE)
Inventor: SHIRKANI GHUNBAR
IPC: F24H1/10
Filed: 1992-06-16
Abstract: The electric instantaneous heater (1) has a box-shaped housing with a cold-water inlet (2), a control arrangement (3), a heating section (5) and a hot-water outlet (7). Cold-water inlet (2) and hot-water outlet (7) are connected movably to the heating section (5) via flexible, preferably electrically insulating lines (4, 6). In the case of a fixed position of the heating section, inlet and outlet can therefore be adapted positionally to a predetermined water-connection pattern, if appropriate even crossed over.

Title: Testing and simulation of bit serial transmission of bit parallel data signals
Inventor: DIEGEL HEIKE DIPL ING
IPC: H04L12/26
Filed: 1992-12-21
Abstract: The test and simulation procedure (TSP) involves transmitting bit parallel information signals with test information and at one rate to a transmission controller (TRANSMIT), running in a test and simulation device (PATGEN). The first information is converted into second bit parallel information which is transmitted to a transmitter (TAXTRANS) at a second rate. After the bit serial transmission over a line (L), a receiver controller (RECEIVER) converts the incoming bit parallel information back into the first bit parallel information at the first rate.An analysis process (AUS) which runs in a receiver test and simulation device (PATTEST) is then carried out. The transmission line (L) is connected at both ends to a transmitter or receiver (TAXTRANS, TAXREC). The transmitter converts bit parallel information into bit serial information which is transmitted over the line. The receiver re-converts the bit serial information into bit parallel information.
