Patent DE-3006702-A1 (DE)
Title: Up-draft power plant using flexible tubular tower - supported by balloon or buoyancy chambers and having guide vanes at base to deflect entering air into turbine
Inventor: BOES CHRISTIAN DR ING
IPC: F03D9/00
Filed: 1980-02-20
Abstract: The updraft power plant is constructed from a flexible tube forming the tower, and as this tube is of light construction, its weight can be supported at the top by a captive balloon or by buoyancy gas chambers built into the tower walls. The captive balloon is so arranged that the upper end of the tower forms a wind scoop and turns constantly into the lee of the wind. The low pressure field behind the upper tube end therefore induces an updraft in the tower, and this energy is used by a turbine located at the foot of the tower. The airstream enters the tower first via a shallow roof structure close to the ground containing guide vanes, which rotate the entering air and prevent it from streaming across the entrance to the turbine and being wasted. The higher the tower, the more efficient the plant, and as the cost of the tower itself in relation to the cost of the entrance structure, is low, it thus pays to build the tower as high as possible.

Title: Adjustment system for tool of press - eliminates eccentric turning moment on support columns by moving reference point
IPC: B30B15/00
Filed: 1980-05-03
Abstract: The adjustment system measures electrically the inclination of a reference surface at the press head in the form of two inclination components w.r.t. a horizontal X-axis and an orthogonal Y-axis. The measurements are passed to an evaluator that serves a display screen with X and Y coordinates. The X inclination component forms the X-axis and the Y inclination component, the Y-axis. The measurements appear as a point in this XY system. The reference point of the tool is displaced against the direction of the vector of this point and by a distance proportional to the vector's length until the vector is zero. The system thereby eliminates unwanted eccentric load moments on the columns.

Abstract: Apparatus for controlling an electronic time piece having two motors M1, M2 comprises only six power transistors T13 to T18 divided into pairs of transistors of opposite conductivity type, the transistors of each pair being connected in series with each other in a respective switching circuit connected between the supply terminals (+,-). The first motor M1 is connected between the middle connection points of the pairs T13/T14 and T17/T18 and the second motor M2 between the middle connection points of the pairs T17/T18 and T15/T16. The pair of transistors T17/T18 is thus common to the two motors. The circuit provides alternating pulses to each motor M1, M2 or may be used to energize two separate windings of a single motor, for reverse and forward drive. If two motors are used, one may drive a seconds hand and a minutes hand, and the other an hours hand and a date indicator. Opposite conductivity type FETs may be used instead of bipolar transistors. <IMAGE>

IPC: H04M9/00
Filed: 1980-09-25
Abstract: The exchange has two controllers to supply certain sub-assemblies within an assembly which are coupled to the signalling lines for evaluating and then displaying the binary signals formed by different amplitudes of the signal line voltage at the receive side.
