Patent DE-2903977-A1 (DE)
Title: IC engine ignition and/or injection control - uses computer control of end stage and two frequency counting steps between two control signals
Inventor: WESEMEYER JUERGEN DIPL ING
IPC: F02P5/15
Filed: 1979-02-02
Abstract: The controlled repeated engine actions, such as ignition and/or injection steps are controlled in dependence on the engine parameters. The control device contains a periodic signal generator, driven by the engine shaft. The signals are used for controlling an end stage in dependence on the engine speed via a computer. In a first period a frequency of two control signals is counter, and the result is supplied in the following period to the computer for evaluation. The signal frequency is counted in a second step, following the counting of the first two control signals, and the result is again supplied to the computer (20) for evaluation Pref. the control signals operate a bistable switching device (14) for alternately triggering one of the two counting processes, each of which is carried out by a separate counter (16, 18). Alternatively, the two counting steps may be carried out in the same counter, the result being taken over by a register prior to resetting of the counter.

Patent DE-3021855-A1 (DE)
Title: Braking control system for preventing wheel lock - cyclically modulates brake pressure to test braking conditions using phase comparator
Inventor: DITTNER ADAM
IPC: B60T8/70
Filed: 1980-06-11
Abstract: A tachometer (2) on the wheel (1) axle gives a speed signal to a differentiator (3), and from thence to one input of a comparator (4). A reference input is derived from a braking reaction sensor (11) on the vehicle frame whose output is also differentiated (12), and applied to a phase comparator (13). The resulting signal controls a reference setter (15), which provides the second input to the comparator (4). The phase comparator (15) also has an input from the tachometer. An oscillator (16) modulates the reference setter, typically by about 5 per cent. The phase shift which this modulation produces between tachometer and reaction sensor is used to further modify the reference, and reduce the braking effort exerted by the brake cylinder (6) via the electro-hydaulic control unit (5), if the friction between wheel and road is low and a tendency to slip exists. The presence of slip produces the phase shift between wheel and reaction signals.

Title: One-piece fibre reinforced synthetic helicopter rotor hub - has one flange thicker than other to take main blade flap bending stress
Inventor: SCHWARZ ALOIS DIPL ING
IPC: B64C27/32
Filed: 1980-07-10
Abstract: The helicopter rotor hub is a one-piece fibr fibre-reinforced-synthetic member comprising two coaxially arranged star-shaped plates of substantially identical outline separated by a spacer, as in 2712706. Each blade mounting is thus a fork with arms flat perpendicularly to the rotor plane. The two plates (1.1,1.2) have a thickness ratio such that the thicker arm (2.2-5.2) of each blade mounting makes the predominant contribution, at least, to its bending stiffness in the direction of blade flap. Where bending forces are large compared with centrifugal forces, the ratio is approx. 2:1.

Patent DE-3107693-A1 (DE)
Title: Rolling stand
Inventor: STOY ERICH
IPC: B21B29/00
Filed: 1981-02-28
Abstract: A rolling stand with two work rolls (2, 3), two intermediate rolls (4, 5) and two back-up rolls (6, 7) (six-high rolling stand) in which axially displaceable intermediate rolls are used in order to roll down strip of a large range of thicknesses, is to be improved in such a way that operations can be carried out under constant conditions of action at as low as possible a Hertzian stress between the work rolls and the intermediate rolls for all strip widths which can be rolled. At the same time, an optimum diameter selection for the work rolls (2, 3) and the intermediate rolls (4, 5) - in relation to the rolling task and the control of the peripheral forces - is to be made possible and, furthermore, problem-free changing of the work rolls (2, 3) and of the intermediate rolls (4, 5) is to be achieved. The aim and object of the axially displaceable intermediate rolls (4 and 5) in this arrangement is to reduce the intensity of the rolling down of the rolled strips in the region of their longitudinal edges and to reduce the especially high stressing of those sections of the work rolls (2, 3) which act on the edges of the rolled stock. Starting from a six-high rolling stand in which blocks (12) fixed to the stand are on the one hand provided with vertical guide surfaces for the chocks (13, 14) of the work roll (2, 3) and the chocks (15, 16) of the intermediate rolls (4, 5) and, on the other hand, have adjusting means for balancing and bending the rolls, and in which certain adjusting means acting against the upper back-up roll (6) can be brought to bear on the chocks (15) of the upper intermediate roll (4), the aim set is achieved by the fact that the chocks (15 and 16) of both intermediate rolls (4 and 5) are assigned adjusting means (22, 38) provided in the blocks (12) as a bending device for the intermediate rolls (4, 5), that a lower and an upper guide piece (19, 20) provided with guide surfaces for the chocks (15, 16) of the intermediate rolls (4, 5), is guided in vertically displaceable fashion on each block (12), and that the adjusting means (22, 38) forming the bending devices for the intermediate rolls (4, 5) can be displaced horizontally, parallel to the axes of the rolls, relative to the guide pieces (19, 20) and/or to the chock (15, 16). <IMAGE>

Title: Device for the generation and optical projection of virtual image compositions
Inventor: SZABO LYUBOMIR
IPC: G02B27/08
Filed: 1981-05-12
Abstract: The invention relates to an optical synthesizer device for the generation and optical projection of virtual image compositions for operating games and for domestic entertainment. According to the invention this is achieved when the device consists of a conusoidal triangular configuration as a game attachment, which is composed of three trapezoidal reflecting surfaces having a side ratio of preferably a = 1; b = 2; c = 3 at an angle of 60 DEG  to one another, in order to produce multiple reflection between the reflecting surfaces x, y, z of the illuminated, real master pattern originals (figures, motifs), which are moved by motor, in order to generate a globular, spherical, virtual, movable image composition that can be controlled individually in light, colour and shape. In contrast with the conventional kaleidoscope, viewing can be performed with two eyes and the three-dimensional effect achieved. The same device conceived as an optical image projector with a lens suitable for the purpose and a condenser lens on the optical axis enables the image composition to be emitted as an optical image onto an image projection screen at full sharpness and any size for many viewers. A second virtual image composition inside the first can be generated by a second device on the optical axis.
