Abstract: Method and apparatus for installation of honeycomb core seals in jet engine mounting rings, including spray deposition of brazing alloy in seals and establishment of compressive relationships between seal and ring prior to brazing of seal in ring.

Abstract: A corneraide device is provided for finishing joints at the intersection of two or more surfaces. The corneraide includes a substantially planar central web with bead members along the edges thereof. Operatively associated with the bead members and extending therefrom are flange members adapted for alignment with the two or more surfaces. Joint compound, wallboard mud, stucco or some similar formable finishing or coating material is applied over the flange members and fayed from the bead members over the respective flange members to the respective surfaces. The corneraide of the invention permits ready alignment on the intersection and efficient application of finishing material thereon. Various embodiments and adaptations of the invention may be utilized to finish arches, window corners, exposed three-way corners, and other structures.

Abstract: An elongated metallic strip is provided which has oppositely disposed convolutions constituted by sinuosities, corrugations, nodes, or the like, and said convolutions are constituted by nadir and zenith convolutions. Provided on the nadir and zenith convolutions are cooperative hinge and locating means assisting in the juxtaposition of said nadir and zenith convolutions to one another, said integral hinge means being provided thereon to facilitate the disposition of such strip into a helical configuration. A seal is provided which is created by helically winding the strip to locate edges thereof in a cylindrical sealing configuration by juxtaposing the convolutions of the strip in operative relationship with one another and welding said convolutions to one another.

Abstract: An apparatus for forming honeycomb-type core strip includes a source of metallic ribbon, form gears for forming a desired configuration in the ribbon and take-up means for taking up the core strip as it is issued from the form gears. Interposed between the source and take-up means is lubricating means for insuring adequate lubrication of the metallic ribbon as it enters the bite of the form gears. The form gears are characterized by a configuration which enables them to impart hinge means to the ribbon which facilitates the utilization of the ribbon in unitary metallic seal constructions wherein a continuous length of the ribbon is bent into helical form.

Abstract: An apparatus is provided for forming a circular, honeycomb-type engine seal from pre-formed core strip having male and female nodes. The apparatus includes a source of strip and means for forming the strip into a circular seal configuration wherein the male and female nodes of the strip are automatically juxtaposed to each other for weldment as relative movement between the forming means and the source occurs to withdraw additional strip from the core strip source. As the relative movement continues, the juxtaposed male and female nodes are exposed to welding head means of the apparatus which welds the male and female nodes to one another. The forming means includes means for causing said relative movement constituted by drive means which is adjustable to permit forming means of different sizes to be utilized. The movement of the forming means permits successive layers or laminae of the strip to be welded to each other in circular form until a seal of the desired dimension is achieved.

Abstract: A panel includes metallic face sheets maintained in operative relationship with each other by a metallic core structure. The core structure consists of a plurality of securement core strips which may be internested or juxtaposed to provide a honeycomb core configuration. Structural integrity is created by the provision of internally generated welds which fasten securement portions of the core strips in operative relationship with the face sheets, but which can be terminated inwardly of the outer surfaces of the face sheets resulting in a very small volume of face sheet material being cast into a weld nugget and being heat affected and maintaining the integrity of the face sheets while, nevertheless, providing maximum structural strength and eliminating face sheet thickness limitations.

Abstract: A machine or apparatus simultaneously manufactures a core-reinforced welded panel and assembles core strips in operative relationship with the face sheets of said panel. The machine includes a first welding head which is insertable in the space between the face sheets and has welding electrode means thereupon which internally weld securement portions of the core strips to adjacent inner surfaces of face sheets of any desired thickness.The welding head includes movable jaws mounting the welding electrodes to move the welding electrodes into engagement with the securement portions of the core strips and the welding electrodes are resilient to permit them to move independently of the movable jaws and each electrode provides an electrically isolated weld.A second welding head is provided which is capable of securing web portions of the core strips by weldments to one another after the weldment of the core strips at their securement portions has been accomplished by the first welding head.

Abstract: A core strip blank is characterized by the provision at its opposite edges of folds or doublers and the resultant core strip has the folded edges disposed substantially normally to the web of the core strip to provide surfaces for the securement of face sheets to the opposite folded edges of the core strip. The resultant core strip can be provided in a variety of configurations and may incorporate such openings or notches as will facilitate the deformation of the core strip into the desired configuration.
