Patent DE-10033632-C1 (DE)
Inventor: LEIST JOHANN
IPC: C03B19/09
Filed: 2000-07-11
Granted: 2002-01-03
Abstract: The invention relates to a device (5) for producing a quartz glass crucible (2). At least two electrode arrangements (7, 8) which are evenly distributed on the periphery of the quartz glass crucible (2) and which produce a first arc and an additional arc each heat a section (14, 15) of a wall (13) of the quartz glass crucible (2), which rotates during this process. The use of multiple electrode arrangements (7, 8) enables the period in which the sections (14, 15) cool off before reaching the next heating area (11, 12) to be shortened, which in turn prevents an undesirable considerable temperature difference in the wall (13). At the same time, the necessary heat output for each individual electrode arrangement (7, 8) can be reduced, which reduces evaporation phenomena and the bubble formation that is associated with this. This not only improves quality but also shortens the production process.

Title: Pressure sensor for vehicle door
Inventor: MADER GERHARD DR
IPC: B60R21/01
Filed: 1996-11-15
Granted: 1997-11-13
Abstract: The sensor dynamically measures force in the millisecond region. The sensor measures the sudden increase in pressure deltap relative to the previous absolute pressure po. The ratio deltap/po is needed because the measured signal delta p is approximately proportional to the absolute pressure po.  A lower threshold frequency is determined. The measuring region only needs to match the dynamic pressure changes because pressure equilibrium occurs over time. The sensor includes a diaphragm.

Title: Servo drive for furniture, e.g. to adjust hospital bed
Inventor: KROGMEIER NORBERT DIPL ING
IPC: A47C20/04
Filed: 1996-11-16
Granted: 1998-04-23
Abstract: The servo drive has a servo motor (12), which is connected to a gear system (14,16,18,24), to drive a linear drive (26). The linear drive terminates in a thrust flange (28). The thrust flange presses on to a hinged lever arm (30), which drives one of the adjustments, e.g. the angle of the back support. For a set angular displacement of the hinge movement, the lever arm is drivingly connected to the thrust flange in a push direction only. After the arm has moved over the set angular displacement, a clutch catch drops into place and the lever arm is drivingly connected to the thrust flange in both push and pull directions. This provides a second drive mode, e.g. to alter a different part of the bed. The clutch catch comprises a pivot arm which is brought into operation by a cam driven by the linear drive.

Abstract: The invention relates to water power engineering, particularly to a hydraulic station, which comprises a low-power hydraulic turbine designed to produce electrical or mechanical power in individual farms for irrigation in areas located near rivers, using the kinetic energy of the flowing water of rivers.The hydraulic turbine comprises a platform, fixed on a shore pier by means of a bearing structure with the possibility of regulating the position of the platform relative to the running water flow level. On the platform are placed a generator or a hydraulic pump and a multiplier, to which is linked a vertical axle, at the end of which is mounted a rotor, which includes radial horizontal bars (11), on which, in turn, are installed blades with hydrodynamic profile. Each blade consists of floating modules (12) with hydrodynamic profile, consisting of finned bodies (13).

The peripheral circuit of screens (18) is made equidistant with respect to the profile of the blades. The modules (12) are assembled by means of locking elements (16) on a common axis (10) and movably attached to the end of the radial horizontal bars (11) of the rotor. The length of the axis (10) is selected depending on the depth of the river. The free ends of the modules (12) are interconnected by a common rod (17).
