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.

Connector bushings and securing or locking elements which may be part of the bushings, for the mounting and fixation of contact pins are arranged in the connector mounting plate. The connector bushings are constructed as carriers for the spring contacts operated in the relay and simultaneously as connector arms for the fixed contacts. The contact pins are connected to respective conductors.

Abstract: An on-board guidance system for a flying body, such as a cruise missile, includes a radar device for a self-sufficient scanning of the topography during flight. Scanning antennas provide signals for evaluation and further application in a search and guide logic circuit. An on-board computer calculates an exact horizon angle which is used as an altitude guide or control value.

Abstract: A sailing yacht having a hull and a sectional mast holding a sail, is equipped with a canard rudder and two rolling keels. Each rolling keel has a ballast container. A three point wing system is formed by wings carried by the canard rudder and by the two rolling keels for producing buoyancy, for steering, and for stabilizing. Thus, the three point wing system has a fore wing (9) forming an end wing of the canard rudder and two aft wings (11, 11') forming end wings of the rolling keels (10, 10'). The rolling keels (10, 10') are tiltable about rotational axes extending above the water line approximately in parallel to the hull axis, whereby the rolling keels (10, 10') are normally above the water line and only the long end (14, 14') of the wing (11, 11') dips into the water, so that the end disk wing (15) functions as a lift producing surface. The ballast is shiftable between two ballast containers 17, 17'.

The subammunition container is permanently attached to the carrier and not intended to be dropped. One section of the device includes a housing (3) containing a release mechanism (4), a computer (5) and a power source (6). The housing (3) is secured inside the carrier (1) at the bottom side thereof. Another section of the device includes the safety device (14) or (25) and the setting or operating mechanism (9). The safety device and the operating mechanism are mounted in the container (2) for the subammunition. The safety device includes a pin (8) that can be moved by a solenoid between two positions. A loop (7) at one end of a rope pull (18) loops around the pin (8) which holds the loop in a first position with a smaller force and in a second position with a larger force.

Abstract: A device for intercepting and retaining of cargo that may have become loose in a transport or baggage compartment or cabin of an aircraft, is located between a freight compartment and a passenger compartment of an aircraft. The device forms an additional protective screen or wall connected to a mounting structure by connection flanges, e.g. the air frame or cabin structures such as the floor and ceiling. The protective screen has at least two wall sections arranged one behind the other with a spacing between the wall sections. The wall sections are joined to each other by energy absorbing elements inserted in the spacing to form a composite, laminated structure. Each wall section has an external covering. The passenger cabin facing wall section may have a decorated surface. The baggage compartment facing wall has a tough material covering to take up impacts, when a piece of cargo should hit the wall surface.

Abstract: A thrust vector control for a jet engine is accomplished by controllable flaps which have an inner, jet flow facing contour with a double curvature. One curvature section is convex and extends between the leading edge of the flap and a transition point. The other curvature section is concave and extends between the transition point and the trailing edge of the flap. The flap or flaps are arranged downstream of the propulsion jet nozzle and are tilted into the jet stream as required for the vector control. A pressure sensor is arranged so as to measure or pick-up a pressure value, preferably near the trailing edge of the flap, which pressure value depends on the dynamic pressure head in that area. The respective pressure value is used in a closed loop control circuit for operating the tilting drive of the respective flap.
