For this purpose a conductor securing device has a disk divided into two half disk sections interconnected by a snap-on connection. Each half disk section has outer elements for holding individual conductors and a bow-shaped shell located centrally inwardly so that two shells of two interconnected half disk sections hold at least one further electrical conductor between the shells. Each shell extends with a shell extension laterally and axially out of its half disk section and the shell extension has as a shoulder for axially retaining a strapping belt.

Abstract: An image motif is transfer printed onto a decor film made of an organic material having a texture surface with ridges and valleys. A stack is formed on a supporting surface by placing the decor film, a motif carrier, and a pressure transfer mat, in that order, on the supporting surface. The motif carrier and the pressure transfer mat are sufficiently flexibly yielding for intimately contacting all surfaces of the decor film when heat and pressure are applied to the stack. The pressure is applied through the pressure transfer mat or in a heatable press.

Abstract: A seat cushion section with a fiber core is elastically deformable and combined with a plastically deformable shock absorber seat section to form a seat structure, for example for an aircraft passenger seat. The fiber core of the cushion section has fibers therein which are substantially continuous or uninterrupted within the core volume because each fiber has only two ends and extends otherwise uninterrupted throughout the core volume between these two ends so that any pin effect of fiber ends sticking out of the cushion is minimized. The shock absorber seat section includes plastically deformable elements, such as honeycomb cells, for protecting a passenger during a crash.

Abstract: A semi-automatic system for finishing a conductor wire harness permits an operator to secure contact elements to ends of conductor wires in a bundle and to insert secured contact elements into a connnector member in a computer aided manner. For this purpose the system has at least one desk type work station for an operator and a harness carrier for holding at least one conductor harness that was assembled, but not finished on a form board. The harness carrier is constructed as a platform for supporting the semifinished conductor harness. The platform is mounted on a movable support in a rotatable manner and for transporting the platform along a factory floor into a position for cooperation with the work station which includes an insulation stripper, a combined contact attachment device and crimper, a connector member clamping device, and a guide beam generator, all of which are computer controlled.

Abstract: A flap door for closing a hatch through a floor separating an upper and lower deck, e.g. in an aircraft, is equipped with a locking and unlocking mechanism in which a locking roller can be moved out of a locking position prior to any force applied to the door in an upward opening direction. For this purpose a bearing block is secured to the body of the flap door and a bell crank lever is journalled in the mounting block. One lever arm of the bell crank lever is constructed as a handle, while the other substantially shorter arm of the bell crank lever carries at its free end the locking roller. In its locking position the locking roller engages a spring biased locking claw. When the flap door is to be opened, the initial angular movement of the handle lever caused the roller to first disengage from the claw and then roll along a guide rail. When the unlocking is completed, the handle lever is in a substantially vertical position enabling the operator to apply an upwardly directed force to the flap door.

Abstract: Surfaces of structural components made of aluminum or aluminum alloys are chemically treated to produce an aluminum oxide coating for improved adhesive bonding to other components or to other surface layers. The oxidizing is accomplished by exposing the surface to be oxidized to a combination bath of an inorganic mineral acid and an oxidation medium for a specific time duration, so that an oxide coating is produced on the surface of the structural components, as a prerequisite for a good adhesion stability of adhesive bonds to be formed after oxidizing.

Abstract: An operating mechanism for an aircraft door performs all the door motions and locking motions for the opening and closing of the door with the aid of electric motors which operate the respective elements of the mechanism through gear drives or through spindle drives to provide the power or torque moment for the respective motion. The door sealing may be accomplished with contact hardware components or with toggle hardware components for taking up the forces resulting from the internal cabin pressure. The door is hinged to the aircraft body structure by a guiding and supporting hinging element, one end of which is hinged to the aircraft body structure while the other end is hinged to the door structure. The door swinging motions in the opening and closing directions, the door opening and closing motions and the door locking and unlocking motions are all performed by program controlled electric motors. Such motors also control the deployment of an emergency escape slide.

Abstract: A spindle of clamping apparatus is adjusted in height or elevation in an infinitely variable manner by means of a transmission. The transmission comprises a pinion connected with a motor meshing with a gear wheel, which is indirectly connected with the spindle. The apparatus is especially useful for clamping large-are a work pieces.

Abstract: Aircraft cabin stairs to connect the aircraft fuselage to a parking area surface gave a frame comprising at least two telescoping segments as well as steps located in the region of the frame. An end segment forms part of the frame by means of side stringers which are present at least in certain regions and which are connected in a telescoping manner to side stringers of a main segment. At least one step in the region of the main segment is mounted such that it is free to slide in the direction of the stairs' longitudinal axis.

Abstract: A jig comprising a plurality of clamping heads arranged in an adjustment device, with each clamping head comprising two elements adjustable in different planes, with one of the actuating elements connected with a suction part which comes to contact the work piece and a vacuum thus pulls the work piece towards this clamping head. The adjustment arrangement is laid out in such a way that each clamping head is movable in elevational, longitudinal, and transverse directions and because of its adjustment possibility any position on the work piece to be machined is accessible.

Abstract: A ceiling baggage storage combination with lighting fixtures for an aircraft passenger cabin with two lengthwise aisles, has a central and two side baggage storage compartments. The ceiling is made of individual curved ceiling elements that extend approximately between the upper edges of the baggage storage compartments. The combination has tube-shaped fluorescent lamps arranged in a direction lengthwise to the aircraft on a respective ceiling element. The ceiling element (5, 11) is curved approximately as a parabola, whereby the less strongly curved zone extends toward the fluorescent lamp (6) which is partly covered by a cover, so that primarily indirect light enters into the cabin. A reflector (7) is arranged on the side of the fluorescent lamp (6) that faces away from and approximately parallel to the ceiling element (5, 11). The reflector (7) reflects the light emanating from the fluorescent lamp (6) primarily toward the ceiling element (5).

Abstract: A locking mechanism for latching cargo pieces to a loading floor of aircraft has two latches housed in a common latch housing. The latching claws face in opposite directions. The latches rotate on journal shafts arranged parallel to the longitudinal axis of the aircraft with a lateral on-center spacing between the journal shafts. Tension springs act eccentrically to hold the latches in their extended locking position. In the locking position the latches support each other by bearing against respective stops. An inclined ramp, provided on each latch and extending in the loading direcion, cooperates with a connecting lever joint to assure that the latches can be rolled over by cargo pieces of full width, while pieces of half the full width are arrested in lateral and vertical directions when the mechanism is located between two pieces of half width closely spaced from each other.

Abstract: For purposes of protecting electrical installations in airplanes against electromagnetic disturbances and especially against overvoltages as can occur for instance as a consequence of a lightning strike, the electrical lines between the individual electrical devices are laid in flexible profiled tubes consisting of electrically conducting material and are rotatably connected with junction elements arranged on one side. At the same time the tubes are connected by means of these junction elements to charge dissipation points provided at the electrical devices. The lines laid in this manner are arranged in overbraiding of plastic material by way of chafing protection. In another embodiment, the chafing protection is provided by a plastic layer on the inside of the profiled tube. In still another embodiment, the chafing protection is itself a hose fabricated of fiber material.

Abstract: A locking mechanism for tying down a piece of freight on a loading floor in an aircraft has a housing (11) recessed in the loading floor. A latch operating member (1) and a latching member (10) are journalled in the housing to tilt toward each other or away from each other. Follower cams (16) of the latching member (10) ride in respective cam guide tracks (15) of the latch operating member (1). A tension spring (20) tends to bias the latching member (10) and the latch operating member (1) in opposite directions in a freight latching position or into a recessed beyond dead center position. Stop members (17, 18) are so positioned on the latch operating member and on the latching member that the latter cannot be tilted without activating the latch operating member which can be rolled over by a piece of freight in one direction when projecting from the housing and in the other direction when recessed into the housing.

Abstract: Decompression panels of this type are used in separation devices such as wall or floor sections which separate a passenger compartment from a freight compartment in an aircraft. For a decompression without damage to the respective wall or floor section, it is necessary to cover or close an opening in the wall or floor section by a panel secured to a rim of the opening by frangible mounting elements that break away in response to a decompression which may be of the blow-in or blow-out type. In a blow-in situation one panel is removed to form an opening. Two panels interconnected with each other are removed in a blow-out situation. In both instances frangible mounting elements break and permit opening a decompression hole in the separation device. All the frangible mounting elements are of identical construction. The arrangement of the frangible mounting elements on one side or on the opposite side of a panel section permits the panel release in the respective direction.

Abstract: A wing type sailing yacht is constructed to incorporate the airfoil principle. Such a yacht has a boat hull, a mast, and a sail, including a bow with a bow keel and a stern with a stern keel. Each keel has a buoyancy control fin (9, 10) at its lower end. An outrigger arm (6, 6') is attached laterally to each side of the hull. The end of each outrigger arm carries a downwardly projecting fin strut which in turn carries a further buoyancy control fin (8, 8'). The buoyancy control fins (9, 10, 8, 8') form a four-point wing or airfoil type system for producing lift or buoyancy and for maneuverability and stability. The outrigger arms (6, 6') are built as narrow surface wing type carriers having a negative sweepback. The arms have a predetermined elasticity. A pontoon (12, 12') is attached to the end of each outrigger arm. The fin struts act as lateral control fins or steering wings (11, 11').
