摘要:
Methods and apparatus' for induction welding a first workpiece to a second workpiece at a welding region may include a metallic strip. The metallic strip may be a mesh. The properties of the metallic strip, such as, for example, pore size, thickness, and density, may be configured to conduct heat uniformly across the welding region and prevent eddy current formation across a workpiece. The metallic strip may be embedded in a workpiece or may be fixed to an induction welding tool that acts on the welding region during induction welding. A removable polymer tape may be disposed between a workpiece and a metallic strip fixed to an induction welding tool. The workpieces may be thermoplastic composite structures and thermoplastic composite stiffeners in aircraft structures.

A retortable container is formed with an opening formed defined by a projecting rim. The rim includes an external surface and securing structure formed thereon. A flexible membrane is sealed to the rim and closes the opening. A closure is provided having a molded plastic tubular ring and a separately formed molded plastic disk. The tubular ring includes an overlapping flange at a top and directed inwardly towards an inwardly positioned open area. The skirt includes an engagement structure for securing the closure to the external surface of the rim. The disk is separately attached to the ring within the open area after the retort process is applied to the sealed bottle.

Thermoplastic welding apparatus and related methods are disclosed. An example method includes providing a smart susceptor between composite parts that are to be joined via thermoplastic welding. The example method includes positioning the composite parts and the smart susceptor on a tooling surface within a cavity of a tooling apparatus and applying a seal to the composite parts and the tooling surface to form a vacuum chamber between the composite parts and the tooling surface at a welding joint of the composite parts; producing a magnetic field at the welding joint. The example method includes providing a vacuum in the vacuum chamber during a welding operation.

Disclosed are a spout stopper with easy open and close operation when being opened or closed, a packaging container, and a packaging container manufacturing method. The spout stopper comprises a spout further comprising a spout tube and base portion, formed by injection molding and disposed upon a spout hole of a packaging container that is formed from a webbing laminate packaging material; a sealed partition of the packaging container that is capable of being ruptured; and a cap that covers the spout. The cap is inserted upon the spout tube in a detachable manner, and comprises a bottom partition, which is partially fused upon the sealed partition such that the sealed partition is capable of being ruptured by the cap, and a pull ring, which is for pulling up on the cap.

An induction foil cap sealer of the present invention includes a cap foil sealer head installed along a conveyor. A controller is operatively connected to the cap sealer head. An infrared detector is adapted to obtain temperature data from a work piece on the conveyor. An electronic memory storage device is capable of storing electronic data, and is operatively connected to the controller. A comparator is in communication with the controller, the electronic memory and the infrared detector. The comparator compares the temperature data with pre-stored electronic data in the electronic memory storage and sends a signal to the controller based on the comparison.
摘要:
A method of fabricating a thermoplastic component using inductive heating is described. The method includes positioning a plurality of induction heating coils to define a process area for the thermoplastic component, wherein the plurality of induction heating coils comprises a first set of coils and a second set of coils. The method also includes controlling a supply of electricity provided to the plurality of inductive heating coils to intermittently activate the coils. The intermittent activation is configured to facilitate prevention of electromagnetic interference between adjacent coils.

A container provides sealed storage for contents. The container includes a composite top member formed of a panel and a frame. The panel includes an opening for providing access to the contents of the package. The frame includes a closure member that is molded in an open position, and which can be moved to a closed position for closing the opening in the panel. The container is formed of a container body in the form of a tubular member formed to a desired shape. The container body is closed using the top member that closes a top opening of the container body, and a bottom member that closes a bottom opening of the container body.
