20090188621 | Lamination cooling system formation method - An electric motor, transformer or inductor having a cooling system. A stack of laminations have apertures at least partially coincident with apertures of adjacent laminations. The apertures define straight or angled cooling-fluid passageways through the lamination stack. Gaps between the adjacent laminations are sealed by injecting a heat-cured sealant into the passageways, expelling excess sealant, and heat-curing the lamination stack. Manifold members adjoin opposite ends of the lamination stack, and each is configured with one or more cavities to act as a manifold to adjacent passageway ends. Complex manifold arrangements can create bidirectional flow in a variety of patterns. | 07-30-2009 |
20100186893 | SYSTEM, METHOD AND APPARATUS FOR FABRICATING COMPOSITE STRUCTURES - Composite structures are fabricated and cured without applying external heat from an autoclave or oven. This technique uses composite preforms to form high strength, three-dimensional co-bonded joints, and thermoplastic conformal mandrels such as rota-molded vacuum bags. The bags form internal tooling within the structure and provide molding with integral fittings that circulate heated air within the bags. The exteriors of the bags are simultaneously under vacuum and exert pressure on the composite elements of the structure that are being cured. This internally-applied heat initially causes to the bags to soften and fully conform to the internal shapes of the structure that are being co-bonded. The heat then transfers into the uncured materials, causing them to cure without unnecessarily heating the entire structure or any required tooling. | 07-29-2010 |
20100258244 | Lateral pipe-lining method and flange-pressing implement for lateral pipe-lining material used in the method - A lateral pipe that intersects a main pipe is lined using a lateral pipe-lining material having a tubular resin-absorbing material impregnated with a curable resin and having a flange formed at one end thereof. The flange of the lateral pipe-lining material is disposed on an expandable flange-pressing implement, and an adhesive is applied onto the flange. Hot water is fed to the flange-pressing implement to expand and press the flange against the periphery of the lateral pipe opening of the main pipe. The hot water thus fed also heats and cures the adhesive on the flange to secure it to the periphery of the lateral pipe opening of the main pipe. The drainage performance of the main pipe can be improved because a gap does not form between the flange of the lateral pipe-lining material and the periphery of the lateral pipe opening of the main pipe, and neither underground water nor earth or sand flows into the main pipe. | 10-14-2010 |
20100282408 | METHOD AND DEVICE FOR LINING A PIPE - A method for lining an interior portion of a pipe includes inserting a vacuum bag having a first end and a second end inside the pipe. A porous media is inserted between the vacuum bag and the pipe. The first end of the vacuum bag is removably sealed to a first end of the pipe. The second end of the vacuum bag is removably sealed to a second end of the pipe. An airtight cavity is formed between the vacuum bag and the pipe. A draw hose is removably connected from the airtight cavity to a resin container. A vacuum hose is removably connected from the airtight cavity to a vacuum source. The vacuum source is activated thereby drawing resin from the resin container into the draw hose and the airtight cavity. The liquid resin is set until the liquid resin has formed a hardened layer. | 11-11-2010 |
20120132361 | MANUAL CONTAINER ASSEMBLY AND LINER INTEGRATION FIXTURE FOR PULP-MOLDED SHELL WITH POLYMER LINER CONTAINER SYSTEMS - A method of using a assembly facilitator for a pulp-molded shell with polymer liner containing systems to precisely create a integral pulp molded shell is disclosed along with the assembly facilitator itself | 05-31-2012 |
20130174979 | PIPE LINER AND METHOD OF USING THE SAME - A pipe liner and a method of using the same are provided. The method includes inserting a pipe liner impregnated with a resinous material into a length of pipe, where the pipe liner has an outer diameter substantially equal to or greater than an inner diameter of the pipe. A bladder having an unstretched outer diameter less than the inner diameter of at least a portion of the length of pipe and capable of stretching circumferentially is inserted into the pipe liner. The bladder is expanded under fluid pressure against the pipe liner, pressing the pipe liner against an inner wall of the length of pipe. The resinous material is allowed to cure and harden, leaving a renewed pipe wall. The length of pipe may have a plurality of inner diameters, and the bladder stretches to produce a smooth interior surface of the pipe liner across the plurality of pipe diameters. | 07-11-2013 |
20140027055 | PROCESS AND MACHINE FOR MEMBRANE LAMINATION AND ARTICLE PRODUCED WITH SAME - Embodiments provide a lamination machine for laminating a membrane to a fabric of an article, such as to an inside surface of a backpack. The lamination machine may include an enclosure with a rotating air connection coupled to a top surface of the enclosure. The membrane may be mated with the article, and then a plug may be inserted in a top opening of the article. The plug may be coupled with the rotating air connection. The rotating air connection may pump compressed air into an interior portion of the article, through an inlet in the plug. A heater may heat the area surrounding the article to activate an adhesive disposed between the membrane and the inside surface of the article. Additionally, the rotating air connection may rotate the plug, thereby rotating the article assembly to facilitate distribution of heat. | 01-30-2014 |
20140326405 | BASEBALL OR SOFTBALL BAT WITH MODIFIED RESTITUTION CHARACTERISTICS - A softball or baseball bat with modified restitution characteristics is provided. The bat can comprise a substantially rigid shell coupled with a single or multi-piece insert. The shell can comprise a tip end, a barrel, a handle taper, and a handle. The insert can be press-fit or adhered to the inside of the barrel of the shell. The insert can be a single or multi-piece design and can be single or multi-layered. The insert can comprise a material capable of impact absorption. Portions of the insert can be separated from the shell with a separation layer to improve restitution in certain areas of the bat. The insert can also comprise multiple layers that are separated from each other with a separation layer to improve restitution in certain areas of the bat. The material and thickness of the insert and the shell can be varied to meet applicable restitution requirements. | 11-06-2014 |
20150101747 | METHODS OF MAKING CONTAINERS - A hermetically sealed container is disclosed that may be produced by an effective and economical process for an in-plant system. The container comprises a coated unitary tray component having a base portion, a side wall portion, and a flange portion; and a lid component hermetically sealed to the flange portion of the tray component. A selected composite polymer film is blow-molded onto an interior surface of the pre-shaped unitary tray structure to provide the coated unitary tray component having its interior surface seamlessly, creaselessly and integrally bonded with the polymeric film. | 04-16-2015 |
