Aspects of the disclosure relate to manufacturing a balloon envelope for use in a stratospheric balloon system. For instance, a stream of polyethylene mixture us extruded. through an extruder in order to orient molecules of polymer chains of polyethylene and to provide an oriented film. The oriented film is passed through an electron beam and thereby crosslinking the polymer chains to provide a cross-linked film. The cross-linked film is heat sealed to form the balloon envelope

An insulating device can include an aperture having a waterproof closure which allows access to the chamber within the insulating device. The closure can help prevent any fluid leakage into and out of the insulating device if the insulating device is overturned or in any configuration other than upright. The closure also prevents any fluid from permeating into the chamber if the insulating device is exposed to precipitation, other fluid, or submersed under water. This construction results in an insulating chamber impervious to water and other liquids when the closure is sealed.

A method for applying a thermoreactive seam tape to a seam is provided. The thermoreactive seam tape may be positioned adjacent to the seam, which may include a first fabric surface and an adjacent second fabric surface. The thermoreactive seam tape may include an interior planar surface that engages both the first fabric surface and the second fabric surface of the seam. The thermoreactive seam tape may further include an exterior surface opposite the interior surface, where the exterior surface is substantially non-planar with respect to the interior planar surface along a length of the thermoreactive seam tape. Heat and pressure may be applied to the thermoreactive seam tape, wherein the heat and the pressure facilitate adhesion of the thermoreactive seam tape to the first fabric surface and the second fabric surface of the seam.

A modular safe room that can be installed in an enclosed space in existing homes, buildings and other occupied structures is disclosed. The modular safe room is constructed from three separate elements and can be sized to fit the desired space. The elements making up the modular safe room comprise tongue and slot elements for attachment to each other.

The invention relates to a method for the manufacture of a breast prosthesis, comprising: providing and superimposing inner and outer plastic foils; welding together the plastic foils to form the circumferential welding seam, thereby leaving a gap to form a filling channel connecting the inner space to an outside; filling the inner space with a fluid curable mass, which is a precursor of the filler material, by injecting the fluid curable mass into the inner space through the filling channel; and curing the fluid curable mass inside the inner space to form the filler material; wherein the filling channel is provided with a check valve to prevent fluid curable mass from entering the filling channel after injection. The invention additionally proposes a breast prosthesis made by such method.

Exemplary embodiments are disclosed of liners, linings, and liquid containment vessels including the same. Also disclosed are exemplary method of providing liners and linings for liquid containment vessels, such as process tanks, immersion tanks, containment pits, gravity feed conduits for transferring or conveying liquid, etc. In an exemplary embodiment, a liner or lining is anchored to at least one structural component by at least one extrusion weld and at least one mechanical fastener. The mechanical fastener is coupled to the structural component. The extrusion weld is coupled to the mechanical fastener. The liner or lining may be anchored to a wide range of structural components, such as a frame, a framework, a frame member, a tank, a wall, a support member, a reinforcing member, an outer shell, a substrate (e.g., concrete, etc.) or sidewalls defining a pit or a gravity feed conduit, combinations thereof, other structures or components, etc.

The present disclosure relates to liners and methods of making liners. The liners may be suitable for use with tanks and other storage/containment vessels, such as process tanks, immersion tanks, indoor or outdoor containment pits, gravity feed conduits (e.g., concrete trench, canal, or drain, etc.) for transferring or conveying liquid, grain storage tanks or containers (e.g., dielectric or electrically non-conductive liners for grain storage, etc.), etc.

A heating unit is described and illustrated including at least two heating devices for at least partially heating with hot air end areas of package sleeves to be sealed, wherein the heating unit has an air supply device for supplying air to be heated to the heating devices, wherein the heating devices each have a heating element for producing hot air and a nozzle unit for blowing hot air produced in the heating device against the end area of the package sleeve. In order to be able to increase the leak tightness of the sealed end areas of the package sleeves without having to accept an excessive outlay and effort in terms of the equipment and/or in terms of the method for this, it has been proposed that the heating devices are each separately connected to the air supply device by means of at least one holder and are each separately held on the air supply device by means of the at least one holder.

An insulating device including an outer shell, an inner liner forming a storage compartment, an insulating layer positioned in between the outer shell and the inner liner, wherein the insulating layer provides insulation for the storage compartment, and an opening configured to allow access to the storage compartment.

An insulating device can include an aperture having a waterproof closure which allows access to the chamber within the insulating device. The closure can help prevent any fluid leakage into and out of the insulating device if the insulating device is overturned or in any configuration other than upright. The closure may also prevent any fluid from permeating into the chamber if the insulating device is exposed to precipitation, other fluid, or submersed under water. This construction results in an insulating chamber that is substantially impervious to water and other liquids when the closure is sealed.
