  • Patent number: 5074805
    Abstract: A terminal case for straight or angled off cable configuration as it extends from a plug connector, particularly for use in aircraft, is provided to have an integral or separate threaded ring and a transition piece of open cross section having sector-like contour, the sector angle decreases away from the ring towards a cable catch. The purpose thereof is to increase the strength of the configuration so that even if the parts are made of synthetic, strength values become comparable with known terminal cases made of metal.

  • Patent number: 4957576
    Abstract: Light conductive fibers being embedded as crack monitors in reinforced compound material are protected as follows. During laminate assembly the fiber ends are slipped into relatively short teflon hoses but being provided to be at least in parts embedded in the compound parts to be made; the ends of the hoses that will be embedded are closed with a cold curing laminate resin; the fiber ends with enclosing teflon hoses will be threaded through laminate openings during assembly of the lamination, and the fiber ends with projecting hoses are also inserted in a conical bore of an assembly device; open areas and portions of the compound part adjacent to the conical bore of the assembly tool are filled with laminate resins; a protective cover is then placed onto said bore and over the teflon hose protected fiber ends prior to curing of the part; and the thus prepared part is cured in an autoclave.

  • Patent number: 4910674
    Abstract: A method of navigation and serial guidance under utilization of elevational data correlation, wherein a correlator compares terrain specific elevational reference data, with actually acquired and processed altitude data, is improved by using a millimeter wave sensor operating in the atmospheric window of about 94 gigahertz; and being operated during cruising by back and forth scanning in a substantially vertical down direction across a prescribed flight path; occasionally the sensor is pivoted about a horizontal axis, for scanning in the forward direction in a forward search mode for purposes of target acquisition.

  • Patent number: 4808238
    Abstract: Aside from certain immediate preparatory steps, the parts are primer coaated and cured on surface parts from which that coating may have to be removed but for which that coating serves as protection; other surface parts are primer coated and the coating is just dried. Following some preliminary assembly of parts the latter surface parts are then painted or lacquered. After completion of assembly the cured coating is chemically removed by a thickened, 20:1 blend of sulfuric acid (H.sub.2 SO.sub.4) and nitric acid (HNO.sub.3).

  • Patent number: 4786013
    Abstract: Flaps mounted on an carriage are being protracted and retracted in relation to a aircraft wing of which the flap is a part by a drive mechanism which is to be provided for variable torque and torque limiting and, if necessary, fixing and holding the position of the flap and its drive carriage in case of failure. A branching gear is driven for the common shaft which drives the flaps of one wing and there are separate transmission paths which include in each instance output shafts from the branching gear, crank drives and thrust rods. One of the thrust rod is directly connected to the flap carrying carriage and the other one indirectly through a load switch and a connecting rod; in addition one of the output shafts of the branching gear is lead into a delta alpha brake having as a second input, the output of the principle drive shaft. The delta alpha brake stops motion of the flap carrying carriage in case there is an angle difference among its input shafts that exceeds a particular limit.

  • Patent number: 4763862
    Abstract: A flap is pivotally mounted on a roller that runs in a track; a three point control lever has one point connected to the roller, a second point to the front of the flap, and a third point is variably connected to a turning lever that drives the flap. The variation is obtained either by providing a secondary lever on the turning lever to obtain a cycloidal path, or a spindel drive just varies the distance between the third point of the control lever and the axis of the turning lever. The turning lever is hollow to accommodate the drive elements for the third point variation.
