Abstract: A device to assemble a skin and a frame of an aircraft fuselage. The device includes first and second brace members that extend along opposing sides of a gap. Arches are spaced apart and fixedly connected to the first and second brace members and that extend across the gap. A strongback is attached to and movable along the first and second brace members with the strongback having a curved shape that matches the plurality of arches. The strongback includes clamps configured to engage with the frame. First and second tension devices apply tension to the skin at the strongback.

Abstract: Systems (100) for assembling stiffened composite structures comprise a layup mandrel (102) and a network (104) of fluid lines (116) configured to be selectively and fluidically coupled to string bladders (118) positioned relative to the layup mandrel (102).

Abstract: In accordance with the present invention, a 31-33 kDa glycoprotein of D. immitis (DiT33) is provided which represents another member of the family of putative pepsin inhibitors. Other known members include Ov33 (a.k.a. Ov33.3, Oc3.6, OvD 5B), Bm33 and Av33. These filarial molecules possess significant homology to the known pepsin inhibitor (Aspi3) of A. suum. Using DiT33 or Ov33, in the form of a recombinant fusion or non-fusion protein, antibody responses to DiT33 may be monitored and used in immunodiagnosis of heartworm infection in mammals. Antibodies reactive with the DiT33 or Ov33 may also be used to detect DiT33 antigen as a means of immunodiagnosis of heartworm infection in mammals.

Abstract: An armoring material single or multilayered is provided with reinforced edge fastening to absorb impact of ballistic projectiles and to prevent delamination of the armoring material from the protected surface when a ballistic projectile strikes it.

Abstract: A battery cap indicator has a transparent cap which permits the viewer to read both electrolyte level and density simultaneously, the indicators also giving the viewer the ability to determine whether the readings are at the higher or lower end of an acceptable range. The float assemblies of the indicator are configured for minimum friction with the guiding structure of the indicator body.

Abstract: A switch assembly for a multiple power cell unit is readily mounted and has the ability to conveniently provide booster capability to a battery by interconnecting the terminals of the cells from an original standby parallel connection to a series connection when terminal connecting busses and their contact elements are moved from parallel to series connection.

Abstract: A battery cap is disclosed which permits visual determination of the state of battery fluid level and density, each of which is shown by one of two indicator flags within the battery cap.

Abstract: A battery cell has a casing and terminal seal construction which precludes leakage and plate and terminals which provide greater power and longer life.

Abstract: An electric storage battery assembly is formed of easily removable individual cell casing units. Each of the cell units is provided on alternate corner edges with vertical dovetail projecting ribs and dovetail grooves. The dovetail ribs and grooves provided on the edges of adjacent cell casings matingly and removably interengage. Conductor straps are provided to removably mechanically and electrically interconnect the electrode terminal posts of adjacent cell units in series arrangement. Longitudinal U-shaped channeled covers may be provided to slidably interlock with the conductor straps connecting adjacent cell casings. A cell casing lid provided with suitable openings and electrolyte-filling bosses is provided to cover and close the open top end of the cell casing.
