Title: Method for designing on a drawing board and device for carrying out the method
Inventor: LINDEMANN HANS
IPC: G06K15/22
Filed: 1986-05-21
Abstract: A new method is described for designing on a drawing board, using a plotter which is to be laid on the drawing sheet of the drawing board, an input unit with a plurality of keys and a control unit, such as a computer or the like, at least one length command and one direction command being sent by the input unit to the control unit for the controlled movement of the drawing nib of the plotter over the drawing sheet. As a result, not only is the production of the rough draft facilitated, but separate digitalisation and inputting of the values into the computer become superfluous. The length command which serves to produce the controlled movement of the drawing nib is composed of a plurality of preferably different length commands. A device for carrying out the method is characterised by a drawing board, on which a plotter rests, a control unit, such as a computer or the like, and an input unit with at least four direction keys by which the drawing nib can be moved in the coordinate system determined by the plotter in accordance with the predetermined length, and by at least four length keys, by which a particular length for the movement of the drawing nib can be predetermined.

Title: Turn-off limiting network for inverters with GTO thyristors
Inventor: PEPPEL MICHAEL DR
IPC: H03K17/00
Filed: 1987-05-23
Abstract: In this turn-off limiting network for limiting the slope of the returning voltage after the turn-off of a GTO thyristor, the series circuit of a capacitor (C1, C2) and a diode (D11, D12) is connected in parallel with each GTO thyristor (T1, T2). The common diode-capacitor junctions are combined via the primary winding of a transformer (L3), the parallel connection of a capacitor (C3) with a resistor (R3) and a diode (D3). The secondary winding of the transformer (L3) is connected via a diode (D4) to the direct voltage source supplying the inverter. To reduce the power dissipation, some of the capacitor energy is fed back into the direct-voltage source via the transformer (L3). The additional introduction of the RC element (R3, C3) ensures rapid demagnetisation of the transformer (L3) without using control components. <IMAGE>

Title: Arrangement for interferometrically measuring distance and thickness
Inventor: RIEMANN MANFRED PROF DR SC TEC
IPC: G01B11/06
Filed: 1987-07-28
Abstract: The invention relates to an arrangement for contactless interferential distance and thickness measurement on transparent objects to be measured. The object is in this case to design the arrangement in such a manner that the measurement is also made possible on objects with curved, non-parallel surfaces and thicknesses of more than a few tenths of a millimetre. According to the invention, the object is achieved by arranging a radiation source for optically coherent radiation as well as two lenses in front of the object to be measured, by expanding the radiation to a divergent bundle of rays by means of the first lens and by converging the radiation, inclined with respect to the surface normal of the object to be measured, to a line or a focus on the object to be measured by means of the second lens. The interference phenomenon (interference pattern) in the overlap region of the two bundles of rays reflected from the surfaces of the object to be measured is used to determine the thickness of the object to be measured in such a manner that the distance of the interference fringes is evaluated as a measure for the thickness.

Title: Rotary-wing aircraft and hang glider
Inventor: KLEINE BRUNO
IPC: B64C29/00
Filed: 1987-09-01
Abstract: Rotary-wing aircraft and hang glider, characterized in that, with suitable positioning, the rotary wing can be moved from hang glider flight into the helicopter position by means of a tilting process. The tilting process can be repeated in flight by changing the incidence angle of the wing blades. The power required to introduce and complete the tilting moment is achieved by changing the incidence angle of the wing blades within one revolution of the rotary wing. If it is expected that the tilting process will not be completed within the permissible time, the process can be accelerated by the interposition of an auxiliary unit.   Changing the incidence angle results in a lower traction force being produced in the front part of the circular area "V" and in the upper part of the circular area "O". An increased traction force is achieved in the rear part of the circular area "H" and in the circular area "U". These different traction forces are intended to produce the tilting moment.

IPC: F02F3/22
Filed: 1987-09-30
Abstract: In a piston in which the skirt (2) is pivotably connected to the piston upper part (1) by way of the piston pin and in which the piston upper part (1) is to be simultaneously cooled, both radially inside and outside an annular support (5) on the head, by cooling oil sprayed on from the crank chamber, a cooling oil supply feasible with simple design means is sought. In order to solve this problem, secondary ducts (10, 11), branching off from the same point, are provided in the upper area of the piston skirt (2). Each of the two secondary ducts leads into one of the head areas to be cooled. Both secondary ducts (10, 11) are supplied by a jet of cooling oil from a nozzle (8), which, at the junction of the two ducts (10, 11), is divided into these. In order to prevent a divergence of the cooling oil jet between nozzle (8) and inlet into the secondary ducts (10, 11), an oil collecting duct (9) of restricted circumference, aligned parallel to the piston axis, is situated in front of the secondary ducts (10, 11) towards the end of the piston skirt. <IMAGE>
