摘要:
A method, medium, and system to receive an indication of an assembly including a plurality of different components to produce by additive manufacturing (AM), determine based on a forward search process that starts with individual components of the plurality of components and iteratively adds other components of the plurality of components thereto in combinations until an entirety of the assembly is accounted for, determine based on a reverse search process that starts with the entirety of the assembly and iteratively removes components of the plurality of components therefrom in combinations until a two-component set is reached, automatically select an optimal combination of the plurality of components from the combinations determined by the forward search and reverse search processes; and transmit the selection of the optimal combination of the plurality of components to an AM controller.
摘要:
A tool usable for working on high voltage lines including a hot stick and a tape dispenser attached to or incorporated in or on the hot stick. In some aspects, the hot stick further comprises an angle arm that may facilitate application of tape to the high voltage line. An attachment between the hot stick and the tape dispenser may be included and may also include such an angle arm. One or more index notched may be included to facilitate alignment of the tape dispenser. A cutter for the tape may be included. Also, associated methods.
摘要:
Machine and method for making air-filled packing cushions from a roll of prefabricated film material having a longitudinally extending inflation channel near one edge of the material and chambers which communicate with the channel through laterally extending passageways. The roll rests on a pair of spaced apart, horizontally extending rollers. The film material is fed from the roll to an inflation tube which extends into the inflation channel, air is introduced into the chambers through the inflation tube to inflate the cushions, and a longitudinally extending seal is formed across the passageways between the channel and the chambers after the cushions are inflated.
摘要:
A method of manufacturing a device having a first elastomeric portion and a second elastomeric portion, the second elastomeric portion being formed into a nonplanar shape, i.e., a vaginal discharge collection device that is formed of an elastomeric rim and a flexible film reservoir, including the steps of loading a rim into a carrier plate, laying film over the rim, heat sealing the film to the rim, preheating the rim and film, drawing the film into a chamber by creating a vacuum to form the collector, and removing the collector from the carrier plate.
摘要:
A spacer-locator with integrated locator pins and spacer tabs for use in joining applications. The spacer-locator provides consistent and accurate spacing between mating surfaces and the locator pins provide enhanced location control of the joining components while providing a mechanical advantage to the shear strength at the joint. Also, a spacer-locator for joining at least two objects along mating surfaces, the spacer-locator constraining at least two degrees of freedom for the objects to be joined.
摘要:
A fiber placement system including a fiber placement station at a first location, the fiber placement station including a tool and a fiber placement assembly configured to construct a reinforcement layup on the tool, the first fiber placement assembly including a compaction roller rotatable about an axis of rotation, the compaction roller at least partially defining a nip, a thermoplastic composite ply extending through the nip and a heating unit positioned to heat the thermoplastic composite ply proximate the nip, and a consolidation station at a consolidation location, the consolidation location being different from the first location, the consolidation station including a consolidation tool and a consolidation system configured to consolidate a reinforcement layup assembly that includes the reinforcement layup.

摘要:
A system for welding an elongate element along a longitudinal direction to a component including a support element comprising a support surface, a magnetic field generating arrangement generating a predefined magnetic field, a carriage comprising contacts supporting an elongate element against movement along the surface of the component in directions perpendicular to the longitudinal direction, a superconducting element being fixedly connected to the carriage, an element cooling device for cooling the superconducting element below its transition temperature, a mover operable to linearly move the carriage, and a welding device for welding the elongate element to the component. The predefined magnetic field defines a linear path along the support surface for the superconducting element when the superconducting element has a temperature below its transition temperature.
摘要:
A thermal welder is configured to weld a back seam of a bag formed of thermoplastic sheet material, which may be a polywoven material. The welder typically includes a weld heater and a compression mechanism downstream of the weld heater to compress the sheet material to form the back seam. The welder also includes a weld breaker downstream of the compression mechanism to break apart incidental welds which are formed adjacent the back seam.
