Presented are repair systems for fixing filler-reinforced polymer structures, methods for making/using such repair systems, and techniques for repairing surface damage/defects of multidimensional fiber-reinforced polymer (FRP) panels. A repair system for fixing a contoured surface of an FRP structure includes a flexible contact sheet that is fabricated from a thermally stable polymer, and has a textured contact surface that seats on the FRP structure and overlays the damaged area. A rigid cover sheet, which may be fabricated from a metal material, a polymeric material, and/or resin-impregnated fiber, has a complementary surface that conforms to the contoured surface of the FRP structure and covers the flexible contact sheet. The repair system also includes a heating element that lays against the rigid cover sheet and applies heat to the contoured surface with a substantially uniform profile that is sufficient to soften/melt portions of the FRP structure neighboring the damaged area.

There is provided a sealing apparatus for a cryopreservation bag, with which a sealing treatment of an inlet/outlet of the cryopreservation bag is carried out automatically and anyone can safely and properly carry out the sealing treatment. The sealing apparatus includes: a bag clamping device 56; a laser device 57; and a scanning structure 58 for moving the bag clamping device 56, for example. The bag clamping device 56 includes a fixed pinching block 67, a movable pinching block 69, and a clamp actuator 70. The laser device 57 includes a laser oscillator 104 and a condensing lens 107. The fixed pinching block 67 includes a block base 73, a heat radiator 74, and a heat radiator holder 75. An infrared laser beam is radiated to a sealed portion 55 of the bag to form a seal bead 125 for sealing in a state in which the sealed portion 55 is pinched and fixed by the heat radiator 74 and the movable pinching block 69 and while the bag clamping device 56, for example, is moved by the scanning structure 58.

A sealing device for sealing a lid material to sealing areas of a blister web comprises a first, heated sealing tool and a second sealing tool arranged opposite each other and movable relative to each other. A first intermediate element of elastic material is attached to the first sealing tool on a side facing the second sealing tool, and a second intermediate element of thermally-insulating material is attached to the second sealing tool on a side facing the first sealing tool. The first and second sealing tools are movable relative to each other between an opened position and a closed position, in which at least sections of the first intermediate element and of the second intermediate element exert pressure on each other. In the closed sealing position, the first intermediate element rests on the lid material and the second intermediate element rests on lands of the blister web.

Disclosed embodiments relate to an induction sealing device for heat sealing packaging material for producing sealed packages of pourable food products. In some embodiments, the sealing device includes: an inductor device which interacts with said packaging material by means of at least one active surface; a flux-concentrating insert; and a supporting body made of heat-conducting material and housing said inductor device and said flux-concentrating insert, wherein said flux concentrating insert is made by a magnetic compound of a polymer and soft magnetic particles; and said flux concentrating insert interacts with said packaging material via at least one interactive surface.

A welding device includes a first graphite heater and a second graphite heater that come into contact with a first member and a second member; and a first die and a second die, which sandwich the first and second graphite heaters with the first and second members interposed therebetween. The first and second graphite heaters have graphite sheets that generate heat by electric power, insulating materials, outer covers, and inner covers, and are configured such that structures of the graphite sheets covered by the insulating materials are interposed between outer covers and inner covers.

A low mass staking module includes a punch having a cavity on a first side, a contact surface on the second side opposite the first side, and a circular flange extending about an outer edge thereof, the punch formed of a thermally-conductive material, an annular housing engaged with the punch about the circular flange at a first end, and a heating element located inside the annular housing. The heating element has an output side in contact with the contact surface of the punch, the contact surface having a shape conforming to a shape of the output side of the heating element. The punch is desirably a low thermal mass punch, while the heating element may be a high power (watt) density, solid state, ceramic, resistant heating element (e.g., aluminum nitride or boron nitride heaters).

A human tissue isolation pouch for use with a sealer machine to indirectly seal human tissue medical pouches while avoiding cross contamination is herein disclosed. The human tissue isolation pouch comprises a rigid frame supporting a high temperature material and having one or more magnets for removably attaching the human tissue isolation pouch to a sealer machine.

During use a medical pouch, which may contain a human tissue sample, is inserted within the human tissue isolation pouch. The jaws of the sealer machine clamp down directly on the high temperature material, thus indirectly heating and sealing the medical pouch inside the human tissue isolation pouch. The sealing machine jaws do not physically contact the medical pouch at any time during the sealing process, and in this way contamination of the sealer machine (and cross contamination of medical pouches from distinct donor cases) is avoided. The rigid frame of the human tissue isolation pouch may be sterilized after each donor event. And the containment bag formed of a high temperature material may be disposed of after each donor event.

The present disclosure is directed to systems and methods for heat sealing plastic packaging. In various embodiments, the disclosure provides a sealing system including a heater block with one or more coupling mechanisms for removable attachment to a silicone shoe. The silicone shoe includes a metal plate coated with or otherwise attached to a mineral-loaded silicone layer, which provides thermal conductivity. The sealing system can be attached to a conventional sealing assembly such that the silicone layer faces a direction toward lids over plastic packages. The silicone layer has a sealing surface which provides heat and pressure to the lids over the plastic packages thereby sealing the lids to the plastic packages. Due to the coupling mechanism, a degraded silicone shoe can be easily detached and replaced with a new silicone shoe.

An exterior body panel assembly having a Class A painted surface, mold-in color or non-Class A surface, and process of infrared welding components of the assembly. Panels of the assembly are placed on a nesting structure and the inside half of the structures are brought together with the other for a fit check. Panels are separated and an infrared heating fixture then heats the various areas to be heated on the panels. The areas on the panels are heated depending on the thicknesses of the parts at each area and surface geometries to be welded. The parts are immediately clamped back together under pressure for joining and cooling of the joined surfaces in the clamped arrangement.

A sealing device generally includes a rotatable support cylinder having an outer, circumferential surface and a heating element disposed about such surface and secured thereto such that the heating element rotates therewith. The heating element is coiled about the outer surface of the cylinder in the form of an overlapping helical pattern. Juxtaposed film plies may be sealed together by bringing the sealing device into rotational contact with the juxtaposed film plies and heating the heating element to a temperature sufficient to cause the film plies to seal together.
