  • Patent number: 8387501
    Abstract: A method and apparatus for rapidly severing a decoy towline extending from an aircraft by a mechanical spring actuated cutting blade and a thermal fuse type of release mechanism eliminating a pyrotechnic actuation device. The cutting blade is biased toward cutting engagement with the towline by a preloaded coil compression spring retained in the loaded position by a length of a polymer cord. The polymer cord has a heater wire wrapped about a portion of the cord which is connected to a DC voltage supply. The heater wire melts the cords when electrically connected to the DC power supply which releases the restraint on the spring which then drives the cutting blade into severing engagement with the towline.

    Abstract: A wire processing unit has a crimp head moved in a ā€œzā€ direction by an eccentric drive and a crimping tool arranged on the crimp head moves with it. The crimp head also moves a pin connected to a lowering unit that has a C-shaped bracket on which the gripper unit is arranged. When a crimping punch moves, the gripper unit is moved with it, and the wire-end held by a gripper pair is inserted into an upwardly-open conductor crimp and an insulation crimp respectively. A cutting head of a cutting unit cuts off the leading wire-end, removes the insulation, and separates contacts with defective crimp fastening from the wire-end.

  • Patent number: 7171884
    Abstract: Steel reinforced tire fabrics are cut with long rigid bar blades, circular disc blades and disc and anvil blades. All of these blades may have an open relatively deep slot spaced close to the cutting edge that creates a resilient cantilevered spring element that includes the cutting edge. In response to cutting forces, the spring element will deflect and form a concave crossover area that improves cutting. A supporting material, particularly a precompressed supporting material, such as a precompressed or stretched polyurethane strip may be inserted into the slot. The supporting material limits or reduces the deflection of the spring element so that the yield strength of the spring element is not exceeded and it returns to its original position when the forces are removed. A precompressed supporting material exerts an outward force on the spring element. A polyurethane strip may be precompressed by stretching it before it is inserted into the slot.

  • Patent number: 5344506
    Abstract: A shape memory alloy (SMA) actuator predeformed in compression actuates a cable cutter mechanism. A cable or other item to be cut is placed between an anvil and a movable blade affixed to the SMA element. The SMA element is heated by an electrical resistance heater to cause it to return to its undeformed elongated state, thereby moving the blade against the anvil to compress and sever the cable or other item. Ones of the shape memory alloy actuator have a plurality of parallelly arranged SMA elements, every other one of which is predeformed in compression and intermediate ones of which are predeformed in tension. The elements are coupled end-to-end so that, when they are heated to cause them to return to their undeformed states, their respective elongations and shrinkages combine at the output to produce an actuation that is the cumulation in the same direction of the changes of all the elements. The plurality of elements may be in a side-by-side or concentric arrangement.

  • Patent number: 4728275
    Abstract: Multi-bladed disc cutter for cutting into pellets thermoplastic material extruded from a die plate of an underwater pelletizer, wherein the blades of the cutter are integrally formed on the periphery of a backplate and radially project therefrom, the sidewalls of the blades being integrally connected by shroud members to provide added strength against bending and twisting of the blades under load. Perforations are provided in the shroud members and backplate to permit passage of water to cool and flush away the cut pellets. Additionally, integrally formed blades may be arranged in concentric circles inwardly of the periphery of the backplate. The integral of the disc cutters avoids weakening and misalignment of the blades, saves space and permits a greater number of cutting edges than is possible in disc cutters wherein the blades are fastened to a hole by bolts. Casting the cutter integrally with its blades permits off-line grinding for final alignment purposes.

  • Patent number: 4656903
    Abstract: A cutter for cutting material in tape form comprises a movable blade of circular segment shape in cross-section and a fixed blade. The movable blade is coupled to a rotating shaft so as to move it in front of the fixed blade. A first support carrying the fixed blade is U-shaped in cross-section, the inside of its bottom being semi-circular. A longitudinal first opening intersects the bottom of the first support and a groove opens laterally into this first opening in its inside surface, the groove accommodating the fixed blade. An auxiliary support is generally trough-shaped and has a bottom which is semi-circular on the inside. A second opening intersects the bottom of the auxiliary support, the edges of which are inserted between the sides of the U shape of the first support. A substantially cylindrical housing for the movable blade is defined between the first and auxiliary supports.

  • Patent number: 4655111
    Abstract: The fiber cutting device of the present invention comprises a die block having a feed opening extending therethrough for receiving a multi-strand fiber. The die block has a flat cutting surface at one end of the feed opening. A fiber feeder is adapted to feed the fiber through the feed opening toward the cutting surface. A rotatable cutting blade is mounted to rotate about an axis approximately parallel to the longitudinal axis of the feed opening, and the blade has a cutting edge adapted to pass in sliding frictional engagement with the cutting surface of the die block once during each revolution of the cutting blade so as to cooperate with the cutting surface to cut the fiber exiting from the feed opening. Adjustable controls are provided for adjusting the speed at which the feeder feeds the fiber through the feed opening, and additional adjustable controls are provided for adjusting the rotational speed of the cutting blade.

  • Patent number: 4456036
    Abstract: In order to allow an adjusting of the bending tools to a given diameter of the wire being bent allowing the producing of the requisite bending radius a central mandrel which forms two bending or forming, respectively, jaws is replaceable together with a shearing tool. To this end a hollow shaft is mounted at the rear of the central mandrel, which shaft is mounted to a supporting shaft by means of a screw joint. The supporting shaft is supported in turn rotationally and can be rotated by means of a motor in order to disconnect the central mandrel. By mentioned rotation the screw joint is released. A special coupling of the shearing tool to an axially movable operating shaft allows a simultaneous disconnecting of the shearing tool together with the central mandrel. A bending mandrel is mountable at locations having various radial distances from the central mandrel.
