摘要:
Methods and apparatus for fabricating adhesive bonded joints while minimizing the voids and/or porosity found in the cured bondline. In accordance with various embodiments, the apparatus comprises an evacuation chamber combined with a pressure inducing device to produce bonded joints that are both void free and thoroughly compacted. The surfaces to be bonded are continuously evacuated throughout the bonding process (pre-mating, mating, debulking and cure). Continuous evacuation is provided via standard vacuum, while the induced pressure can be pneumatically or mechanically provided.

A process for packaging a product (P) arranged in a support (4) comprising unrolling a film (10a), transversely cutting the unrolled portion of film (10a) and preparing cut film sheets (18), moving the cut film sheets (18) to a packaging assembly (8) defining at its inside a packaging chamber (24), progressively moving a number of supports (4) inside the packaging chamber (24) of a packaging assembly (8), keeping the packaging chamber (24) open for a time sufficient for a number of supports (4) and for a corresponding number of film sheets (18) to properly position inside said packaging chamber (24), hermetically closing the packaging chamber (24) with the film sheets held above the respective support (4) and at a distance sufficient to allow gas circulation inside the support (4), optionally causing one or both of: a gas withdrawal from the hermetically closed packaging chamber (24) and gas injection of a gas mixture of controlled composition, heat sealing the film sheet (18) to said support (4), wherein the cutting of the film (10a) into film sheets (18) takes place outside the packaging chamber (24) at a station remote from the location where the film sheets are coupled to the supports. An apparatus (1) for performing the above process is also disclosed.

Featured is a vascular access device such as an IV catheter device including a housing, a tubular member and a seal member, and a securing mechanism. The housing includes a proximal and distal portion and a chamber that extends between the proximal and distal portions. The tubular member is coupled to the housing distal portion so it is fluidly coupled to the chamber. The seal member is disposed within the chamber and the securing mechanism secures the seal member distal end to the housing proximal portion so the seal member is sealingly and compressibly retained between a chamber proximal end and the securing mechanism. Such a seal member also is constituted so a portion of the seal member moves axially responsive to an axial force applied to the proximal end.

In one embodiment a method to form a composite part comprises joining a first structural element and a second element to form a fillet at an intersection of the first structural element and the second element, positioning an inflatable radius filler in the fillet, positioning the composite part in a vacuum chamber, venting the inflatable radius filler to an environment external to vacuum chamber, drawing a vacuum in the vacuum chamber, and curing the composite part. Other embodiments may be described.

Systems (200) and methods (1300) for selectively retracting a first component of a Vacuum Packaging Appliance (“VPA”). The method comprises: causing the first component to normally be in an engaged position in which the component facilitates a formation of a heat seal along an open end of a container disposed within the VPA; detecting an existence of at least one first condition associated with the VPA; and applying a magnetic field in proximity to the component when the first condition is detected, whereby the first component is at least maintained in an unengaged position in which the first component no longer facilitates the formation of the heat seal.
摘要:
A device for welding a plurality of foils to one another by means of a laser, for use in a packaging machine, comprises a clamping unit configured for applying pressure to a plurality of foils in a predetermined area as well as for conducting the laser radiation used for the purpose of welding to this area. A method for welding a plurality of foils to one another by means of a laser in a sealing station comprises welding the foils to one another along a sealing seam by means of the radiation of the laser while pressing them together in the area of the sealing seam.

A work station for a packaging machine comprises a tool structure and a tool movable relative to the tool structure by means of a drive. The drive comprises at least one countermagnet which is operatively connectable to an electromagnet and movable relative to the electromagnet. The drive further comprises a mechanism by means of which the movement of the tool is unidirectionally coupled to the relative movement of the countermagnet relative to the electromagnet.
摘要:
A method for fabricating an air-filled cellular structure for use as a resilient cushion. The method includes providing a molding structure including a shelf substantially surrounding a depression, and a platform that fits within the depression and is selectively movable between a plurality of positions relative to the shelf, moving the platform to a preselected position relative to the shelf, wherein the preselected position corresponds to a substantially predetermined amount of air to be contained by the air-filled cellular structure, and using a vacuum device to draw air from within the depression. The method further includes engaging a first portion of a first expanse of generally air-impermeable material with the shelf, whereby the vacuum device draws a second portion of the first expanse of material against the moveable platform, and bonding a first portion of a second expanse of generally air-impermeable material to the first portion of the first expanse, thereby enclosing a volume of air between the first and second expanses. The method may further include bonding a third portion of the first expanse to a second portion of the second expanse, thereby decreasing the volume of the air enclosed between the first and second expanses.
摘要:
A manufacturing apparatus of a lighting device, including a vacuum chamber, an exhaust system by which the vacuum chamber is set to a reduced-pressure state, and a transfer chamber from which a substrate is transferred to the vacuum chamber is provided. The vacuum chamber of the manufacturing apparatus includes a plurality of deposition chambers in which a first electrode, a first light-emitting unit including at least a light-emitting layer, an intermediate layer, a second light-emitting unit including at least a light-emitting layer, a second electrode, a sealing film are formed, and a substrate transfer means by which the substrate is sequentially transferred to the deposition chambers.
