Patent number: 6823918Abstract: The present invention generally relates to a multi-layered structure which for a given external geometry a section of interest may be integrally reinforced by varying the relative proportions of the layers in that section. That is, the layers making up the structure may have varying relative proportions to the structure's overall thickness between two or more positions while the structure maintains a constant thickness between the positions. By varying the relative proportions of the structure's layers, the mechanical properties of the structure may be selectively altered from a first position to a second position without altering the structure's external profile. This is especially desirable in composite sandwich structures used in aerospace applications which often require additional reinforcement at structural interfaces.Type: GrantFiled: December 28, 2001Date of Patent: November 30, 2004Assignee: Lockheed Martin CorporationInventors: Duane D.

Patent number: 6047756Abstract: In order to reduce the weight and cost of LPG pressure-resistant containers, thermo-plastic resin is used in the continuous formation of a hollow container wherein the outer surface of a hollow continuous liner is continuously braided with multiple yarns. The present invention is a system for forming a braided hollow container comprised of a continuous liner forming section 1 which continuously forms the continuous liner 70 for the inner layer 72 of the hollow container in the axial direction through a hollow joining section 71, a braid forming section 2 which uses a braiding machine BR to braid the outside of the continuous liner to form the continuous braided body 73, cutting section 3 which cuts the continuous braided body in the radial direction in the hollow joint section, and a plug welding section 4 which welds a plug 75 to the openings formed by the cutting section; and the pressure-resistant container formed using said system.Type: GrantFiled: June 10, 1998Date of Patent: April 11, 2000Assignee: Murata Kikai Kabushiki KaishaInventor: Hiroshi Uchida

Patent number: 5888339Abstract: An apparatus for wrapping a joint of pipe with a web of reinforced concrete includes an improved applicator that wraps the joint of pipe with a web of concrete that is reinforced with a steel mesh and which is also layered with a web of poly film. The improved applicator has a motor drive and a gear box that interfaces the motor drive with one of the belt pulleys that drives the applicator belt. The primary applicator belt can be disengaged from the pipe, thereby transferring both pulleys to idler pulleys after pipe wrapping is initiated. This allows the large motor drives that actually rotate the pipe to control the speed at which the web of concrete is applied to the pipe. The motor drive for the applicator belt is initially engaged for a few seconds to overcome initial friction associated with start up of the applicator. A timer can be used to regulate the number of seconds that the applicator motor operates until it is disengaged using the clutch.Type: GrantFiled: June 7, 1996Date of Patent: March 30, 1999Assignee: Bredero Price CompanyInventor: George Hanson

Patent number: 5694734Abstract: A material having fibers in a curable matrix is applied as a reinforcement to a vertical column. The matrix is cured by providing a reinforcement curing apparatus including a steel cylindrical housing split lengthwise into at least two sections, and a plurality of elongated radiant heaters mounted to an interior wall of the housing and oriented to direct their heat inwardly. The curing apparatus is assembled around the perimeter of the column having the reinforcement thereon and operated to heat and cure the reinforcement.Type: GrantFiled: December 18, 1995Date of Patent: December 9, 1997Assignee: XXSYS Technologies, Inc.Inventors: Larry Cercone, Nicholas J.

Patent number: 5516391Abstract: The present invention provides an endless belt including a reinforcing load-carrying layer which is constituted by an even number of cord-like load-carrying members (5, 6). The load-carrying members extend within the load carrying member having a load-carrying layer in a plurality but at least more than one full turn each. In order to balance unbalanced force components produced by the load-carrying members having a pitch angle, the load-carrying members are arranged in pairs. Each load-carrying member would in one transverse direction has a corresponding load-carrying member wound in the opposite transverse direction within they load-carrying layer. Only within the same longitudinal transition zone (A) of the load-carrying layer the load carrying members form a pitch angle each with respect to the longitudinal direction of the belt.Type: GrantFiled: October 7, 1992Date of Patent: May 14, 1996Assignee: Fenrir AGInventors: Jonathan Schanin, Shmuel Harel

Patent number: 5405485Abstract: A payguide mounting bracket assembly is connected to a support stand, and a spool is connected to the payguide mounting bracket assembly to have a fiber optic coil formed thereon. A pair of payguide assemblies are demountably coupled to the payguide mounting bracket assembly. A robotic manipulator assembly is configured to decouple a selected one of the first and second payguide assemblies from the payguide mounting bracket assembly and move the selected payguide assembly to a location adjacent the spool such that a layer of optical fiber is paid out to the spool from the selected payguide assembly as the spool and payguide mounting bracket assembly rotate relative to the selected payguide assembly. The invention also preferably comprises further comprises an epoxy applicator assembly configured to be demountably coupled to the robotic manipulator assembly for movement to a location adjacent the coil for applying epoxy to the coil.Type: GrantFiled: January 14, 1994Date of Patent: April 11, 1995Assignee: Litton Systems, Inc.Inventors: James A.

Patent number: 5320702Abstract: A press blanket for a press device in a paper making machine, or the like, is formed of an elastomeric blanket material and fully embedded layers of reinforcement threads. The radially inner layer is formed of longitudinal threads which extend parallel to the axis of the press blanket. The radially outer layer is formed of circumferential threads which are wound in the direction of blanket motion and are wound generally helically. The threads are fully surrounded by the layer of homogeneous elastomeric material, that is formed from a single pouring. The circumferential threads have a diameter of at most 1/500 of the outside diameter of the fully rounded press blanket. In a unit area of the press blanket, the tensile strength of the circumferential threads is at least 40% greater than the tensile strength of the longitudinal threads.Type: GrantFiled: March 31, 1992Date of Patent: June 14, 1994Assignee: J.M.

Patent number: 5039368Abstract: Thermoplastic matrix composite cylinders, pipes, and other hollow bodies are formed by a winding technique using thermoplastic filaments. The filaments are fed from a vertically moving winding head onto the surface of a rotating mandrel. The filaments are preheated to soften them and then pass beneath a heated compaction roller bearing against the mandrel. The compaction roller is castered so as to follow a helical path. Several plies of the thermoplastic material may be laid down in this fashion, the surface of each prior ply being heated so that the layers fuse properly. When cooled to below its solidification temperature, the formed object is removed from the mandrel.Type: GrantFiled: September 25, 1989Date of Patent: August 13, 1991Assignee: Thiokol CorporationInventor: Mark A.
