  • Torque measuring device
    Patent number: 4470312
    Abstract: A torque measuring device has a torsion bar with effective length adjustable to show different energy absorption capability. One end of the torsion bar's effective length is held stationary while a torque from a torque controlled winding tool is applied to the other end through a one direction of rotation clutch. The actual torque applied to the torsion bar is measured after which the torque on the bar is released.

  • Breakaway duct coupling
    Patent number: 4469354
    Abstract: Flanges (12, 14) attached to duct sections mate to form a ribbed portion around the circumference of the ducts. A plurality of U-channel shaped sections (50, 52, 54) are placed over the ribbed portion with a band (40) holding the sections in place, thereby securing the coupling. Each U-channel section is formed of parallel side sections (20, 22) secured to a segment via shearable fasteners (26). A sufficient bending load to the ducts causes shearing of the fasteners thereby releasing the duct coupling.

  • Directional control device for aircraft
    Patent number: 4466586
    Abstract: A yaw control arrangement for tailless aircraft utilizing a plurality of rudder-like surfaces which are normally retracted into the surface of an aircraft wing and extended only momentarily on demand to generate a yawing moment.

  • Automated feed for a punch press and method of using same
    Patent number: 4436007
    Abstract: A stack of strips of feed stock are placed on an adjustable height table. The strips are positioned on the table by arms which align the stack to the centerline of punching dies in a punch press. A pneumatic actuated head uses vacuum cups to raise the end of the top strip and insert it into in-feed rolls. The drive means for the in-feed rolls also drive an encoder which signals roll movement as the rolls incrementally feed the stock into the punch press. Drive means for the feed stock switches to the out-feed rolls once the blanked out stock reaches those rolls, and when the end of the strip passes through the punch press, a control unit is signaled and a new strip is fed into the system.

  • Decompression equalization relief valve
    Patent number: 4432514
    Abstract: A pressure relief device extends between the double side walls of a passenger compartment of an airplane to communicate with an adjacent cargo compartment. A duct is formed between a perforated section of an inside wall and a panel extending from the inside to the outside wall. A spring closing, pivotally mounted valve extends across to close off the duct and has perforations to permit air flow through the closed valve at low pressure differential between the compartments, but the valve will open at sudden high differential pressures.

  • Directional coupler for optical communications system
    Patent number: 4423922
    Abstract: A directional coupler for an optical communications system of the type utilizing non-collimated optical beams transmitted by waveguides. The coupler includes an input waveguide, a network waveguide, and a detector port, and has a beam-directing surface positioned between the input waveguide and the network waveguide. The beam-directing surface defines an opening aligned with and adjacent to the input waveguide, and a beam conducting medium fills the space between the two waveguides. Input optical beams are transmitted from the input waveguide through the opening to the network waveguide, and output optical beams are transmitted from the network waveguide to the beam-directing surface. The core area of the network waveguide is large relative to the opening, and the output optical beam expands as it travels through the conducting medium to the directing surface.

  • Ram assembly for electromagnetic riveter
    Patent number: 4417463
    Abstract: A ram assembly for an electromagnetic work tool which includes a ram shaft, conductive driving plate, and insulator plug, which elements are bonded together to form an integral ram assembly thereby reducing shear stress on the insulator plug since no counterbores or screws are utilized in the ram assembly. The insulator plug utilizes a composite of unidirectional glass fibers in an epoxy matrix, which glass fibers are oriented parallel to the axis of the ram shaft thereby providing superior load distribution of the insulator plug. A reduced number of interfaces in the ram assembly provides less interfaces for reflection of shock waves.
