Abstract: A laser warning receiver or detector for the detection of extraneous light not emanating from the laser to be detected. Thus, extraneous light is differentiated from incoming laser light. The laser radiation coming from a laser to be detected is detected on the basis of its time coherent radiation. Simultaneously, the wave length as well as the pulse form or shape are analyzed in spite of any presence of incoherent radiation components.

Abstract: A broadband nonlinear drive control network for linear amplifiers with several amplifier channels has a first branch (Z1) with an adjustable amplitude limiter (A) connected to a signal source (S) through an impedance inverter (B), whereby an increasing impedance is produced at the signal source (S) when the limiter is activated. A variable resistor (C) is connected to the signal source (S) in a second branch (Z2). The resistor (C) begins to conduct only above an adjustable high frequency signal voltage. The amplitudes at the limiter (A) and at the resistor are tuned to each other so that the load impedance at the signal source (S) remains constant. Linear branch signal combinations provide the drive control voltages for the individual channels (K2 . . . Kn). A portion of the power output of the branch (Z1) directly drives the amplifier channel (K1).

Abstract: A combination engine for a flying craft capable of flying at speeds within a wide range from subsonic speeds to hypersonic speeds, is equipped with a rocket engine section that is independent of an atmospheric air supply, and a turbo air jet engine section having a compressor which is driven by a turbine that is also independent of an external air supply. The combination may further include extra fuel supply nozzles for operation as a ram jet which uses the same flow channel as the turbo air jet engine section. A gas generator equipped with two valving mechanisms is arranged coaxially with the rocket engine section. The valving mechanisms are controllable to open the gas generator chamber to the rocket combustion chamber while closing off gas flow to the turbo air jet section or vice versa. Either section can work alone or in parallel and simultaneously with the other section.

Abstract: A laser diode in the form of a chip with a heat sink connected to an electronic control circuit, is positioned in front of a light conductor for emitting light into the light conductor. The light conductor (103), such as a fiber (101) of a glass fiber cable (102), passes through a hole in the wall of a housing (100) for the electronic control circuit. The light conductor end is precisely adjusted in the Z-direction of an X-Y-Z-coordinate system, and rigidly held in the adjusted position in a bore or slot (17a) of a mounting block (17). The laser diode (10) with its chip (11) and its heat sink (12) are held in a roughly adjusted position in a milled recess (17c) of the mounting block (17) relative to the tip of the light conductor by a compression leaf spring (14) which permits an adjustment of the laser diode with its chip and heat sink in the X- and Y-direction for a precise adjustment. A displacement gripper tongue mechanism is then used for a precise position adjustment in the X- and Y-direction.

Abstract: The amplification efficiency is increased in a system for linear amplification of signals, especially in satellite transponders, by connecting at least three amplifier impedance inverter units in parallel to each other between an input signal control network and a common load. The reactive loading of the individual amplifiers is compensated by shunt susceptances at the output ports of the individual amplifiers.

Abstract: The invention relates to a safety device for motor vehicles in the form of an impact protection arrangement, wherein the pot-shaped housing of the sensor for the activation of the ignition device of the gas generator, has a form fitting with the flange of the gas generator housing, and is attached to it in such a way that part of the gas generator housing is contained in the sensor housing, thereby forming an air gap which is electromagnetically shielded against interfering influences. An example embodiment is described and shown in the figures of the drawings.

Abstract: The junction between two optical fiber light conductors is protected by a sleeve envelope which connects the protection coatings directly to each other. Tension resistent filler fibers are compressed by a shrink fit inside the sleeve envelope so that tension stress bypasses the light conductor fibers through the filler fibers. The sleeve envelope ends are shrink fitted to the protection coating. The highly tension resistant filler fibers, surrounding and bridging the junction, are tightly enclosed in the sleeve envelope by the shrink fit so that tension stress also passes through the filler fibers, thereby permitting the sleeve envelope to perform its protection function while the filler fibers provide the required strength.

Abstract: A laser operation such as a laser welding operation or a laser cutting operation is improved in its quality and a consistently high quality is achieved by arranging auxiliary tool units upstream and/or downstream of a main laser tool unit including a primary laser head on a common tool carrier. The secondary tool units upstream of the laser operation are intended for a preliminary surface treatment to present the most appropriate surface conditions for the following laser operation. Similarly, the tool units arranged downstream of the laser operation are intended for subsequent work operations such as an immediate cleaning operation, a coating operation or the like to avoid a reoxidation of the welding seam or of the cut edge of the work piece. The secondary tools make sure that the laser operation is enhanced or improved either by presenting optimal conditions for the laser operation or by improving the work piece subsequent to the laser operation.

Abstract: A semiconductor optical image sensor is constructed particularly as a CCD-structure having a linear or two-dimensional array configuration with parallel or serial read-out. The CCD-structure is combined with an avalanche diode structure arranged on one side of the semiconductor or in laterally spaced locations to allow an optically controllable amplification of the image signal in the image sensor by an avalanche effect.

Abstract: A recognition system for alarming and early warning against starting and approaching flying objects with an active engine evaluates the "plume signature" of such an engine. Image signal generating electro-optical sensors, which operate in a preselected spectral range, are combined with an image processing and evaluating arrangement for producing output signals that can initiate countermeasures semi-automatically or automatically after a threat analysis has established that a threat exists.

Abstract: Preimpregnated fiber reinforced tapes, so-called prepregs, are dispensed and deposited in a molding and bonding apparatus by a device in which a supply spool or roller carrying the tape is supported by a carrier having an adapter for connection to an arm of a conventional industrial robot. The carrier also supports feed rollers for advancing the tape and a cutter for cutting the tape. The feed rollers are secured to a support which in turn is secured to a fixed member by guide elements and biasing springs for a vertical guiding of the support movement. All drive members are controllable, so that all functions can be performed under the control of a computer in accordance with a program stored in the computer. Thus, the tape dispensing, application, and cutting takes place substantially automatically.

Abstract: In a pivotable seat especially for a flight attendant in an aircraft, the backrest and the seat part are constructed to be pivotable together about an approximately vertical axis when the seat part is pivoted about an approximately horizontal axis into an upright position. The seat is secured to a carrying structure of the aircraft. The seat plate (25) and the backrest carrier plate (27) are milled parts. A spring is activated by tilting the seat part (2) into an upright position, whereby the seat 1 is biased into a recess (15) for storage. For pivoting the seat out of the use position into the recess (15) during non-use, only the locking of the seat part must be released and the seat part tilts itself into the vertical position, whereby the mentioned spring is activated for pivoting the seat into the recess (15) and locking it automatically in the recess.

Abstract: In an opto-electronic sight, including several optical devices, the separate optical axes are combined by means of mirrors and beam splitters so that all the beam paths amay be directed exactly at the same sight point, either directly or via a directing and stabilizating mirror. Axis alignment errors and the need for axis adjustment are eliminated.

Abstract: A method and apparatus for steering a moving object is based on an electro-optical sensor unit which selectively detects the UV-radiation generated by a flying body or projectile. The signals resulting therefrom are processed and converted by a computer into steering and control signals for the object to be steered, whereby the locating probability and the interference reliability are improved.

Abstract: A solar collector panel arrangement includes a plurality of panels interconnected to form panel wings which in turn are secured in a symmetric fashion to a spacecraft, especially a satellite. At least the axially outermost panels forming the tip of a panel wing, are partially and/or fully foldable while the other panels of the wing are fully unfoldable. In the fully unfolded state of a wing all panels are located in a common plane in which also the system central axis is located. The two solar generator wings are so folded and structured or arrestable in certain positions that the entire center of gravity in the partially unfolded state remains in the same position as in the fully unfolded state and in the fully folded state.

Abstract: A process for data transmission uses a geo-stationary satellite and at least one sub-satellite, the sub-satellites being placed on lower orbits. For the transmission of news, at least two data streams are transmitted with different powers. The first data stream, with a higher power is used for linking with the geo-stationary satellite (S.sub.1) and the other data streams are transmitted by means of PN (pseudo-noise) sequences for linking with the sub-satellites (S.sub.2). Two data transmissions thus take place in the same carrier frequency, but involving different satellites that are both within the visibility range of an earth station. This type of transmission using additional data streams of information is suitable for controlling and/or regulating the exchange of news between satellite-satellite and/or earth-satellite-earth or for controlling or regulating the orbit of the satellites.

Abstract: A spherical space, especially a hemispherical space, is scanned by an optical scanner for the presence of a target in the scanned spaced. The optical scanner includes an objective lens (4) which scans the space through an optical deflector (1 or 7) arranged upstream of the objective lens and rotatable about two axes, one of which is the optical axis (2, 3) of the objective lens. At least one tiltable prism (5) is arranged downstream of the objective lens (4). At least one row of sensors (6) is arranged downstream of the prism (5) for converting received optical signals into respective electrical signals which are processed under control of a central processing unit (CPU) including a computer and memory (21). Drives (9, 16) controlled by the CPU rotate the deflectors (1 or 7) about the two axes (2, 3) extending perpendicularly to each other. The imaging speed at which an image passes the detector row (6) is always constant independently of the instantaneous viewing or scanning direction.

Abstract: In a semiconductor element having a semiconductor body, an electrode structure is arranged on at least one major surface of the element for storing charge carriers of at least one conductivity in cells formed by the electrode structure. Control electrodes which are at least partially enclosed in the semiconductor body are arranged in at least one plane essentially parallel to the major surface of the semiconductor body. The control electrodes similarly enable charge carriers to be stored in defined cells. The control electrodes stored also make it possible to shift stored charges from one cell to another, whereby at least two independent charge images can be stored in a three-dimensionally arranged storage cell pattern.

Abstract: Two laser distance measuring functions are preformed on board of a ground-hugging cruise missile by at least one laser distance meter for taking downwardly directed altitude measurements and diagonally or slantedly forwardly directed distance measurements for producing corrected altitude signals for use in controlling the flight of the missile. Both types of measurements can be made by one laser distance meter that is tiltable in the required direction or two laser units are provided. The correction provides a clear recognition of artificial fog by evaluating both types of measured values in an intelligent signal processing unit which compares the intensities of the measured values from the same ground locations, determines the extinction coefficient of the fog and takes the angular distribution of the back-scattering intensity of the laser beams into consideration for correcting the altimeter readings.

Abstract: A structural panel, for example for forming interior aircraft cabin walls, has a lightweight composite panel substrate, an aluminum sheet, adhesively bonded to the substrate, and a desired visual image or attractive colored pattern on the visible surface of the aluminum sheet. The panel is produced by first cleaning the substrate surface to be decorated; applying an adhesive layer (5) to the cleaned surface; adhering or pressing an aluminum sheet (6) onto the adhesive layer (5); curing the adhesive layer (5); cleaning the aluminum sheet (6); applying and curing a base coat layer (7); and applying a number of colored layers (8) to produce the desired visual image or pattern.
