A method of joining panels for a vitrine is disclosed. The ends of the panels to be joined are mitered cut and bonded with a suitable adhesive providing adequate adhesion and transparency. The joints are formed to provide a wedge-shape bond gap sufficient to allow application of the adhesive from the outside of the gap through capillary action. The adhesive may be catalyzed or ultraviolet- or light-hardened.

A joining structure includes a first member, a second member of a material different from that of the first member, and a separation mechanism provided between the first member and the second member and that separates the first member and the second member from each other, wherein a resin is filled into the space between the edge of at least one member among the first member and the second member, and the other member.

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 device and method for inductively heating package sleeves including: at least one unit for producing an alternating current, at least one inductor having at least one effective section, and a holding unit having a front holding area and a rear holding area for mounting the inductor, wherein the inductor is connected to the unit for producing an alternating current, and wherein the holding areas arranged in such a way that a gap is formed between the front holding area and the rear holding area, the longitudinal direction of which gap corresponds to the conveying direction of the package sleeves. The effective sections of the at least one inductor may be at least in sections arranged asymmetrically to one another in relation to a center plane lying in the gap.

A packaging apparatus with an improved pinch roller apparatus, fluid supply apparatus, and/or a sealing apparatus. The pinch roller apparatus (e.g., comprising one or more guide and/or pinch rollers) is used to deliver film material to the fluid supply apparatus (e.g., nozzle and blower apparatus, or the like) that fills one or more chambers of the film material with fluid (e.g., air, gas, or other like fluid), and the film material is then sealed by a sealing apparatus (e.g., using one or more heating elements with an improved temperature sensor configuration) that seals the fluid within the one or more chambers in order to form the inflated article (e.g., inflated packaging material). In particular, the sealing apparatus provides improved sealing through the improved accuracy of the temperature reading in the heating zone, in part, by locating a sensor between a heating element and a protective member that covers the sensor.

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.

Aspects of the disclosure relate to manufacturing a balloon envelope for use in a stratospheric balloon system. For instance, a stream of polyethylene mixture is 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.

A system for forming a tendon sleeve on an atmospheric balloon is described herein, the system comprising a coupling assembly including a seam coupling mechanism that forms a seam joint between a first gore panel and a second gore panel, the seam joint is spaced from respective first and second lateral edges of the first and second gore panels to form first and second edge flanges, and an edge coupling mechanism that forms an edge joint between the first and second edge flanges and closes a tendon sleeve, the edge joint spaced from the seam joint, the tendon sleeve includes a tendon sleeve passage between the seam joint and the edge joint and between the first and second edge flanges. The system also includes a tendon positioning mechanism that positions a tendon within the tendon sleeve passage. A tendon sleeve formed by this system is also described herein.

A reinforced polybag and methods of manufacturing the same are presented. A method of making a reinforced polybag involves: providing a plurality of walls; providing a hole in a wall of the plurality of walls such that a remaining portion of the wall separates the hole in the wall form a side edge of at least one side edge of the wall; forming the polybag out of the plurality of walls by attaching each wall in the plurality of walls along the at least one side edge of that wall to at least one adjoining wall; providing a synthetic resin fiber mesh cover to cover the hole in the wall; and attaching a peripheral portion of the synthetic resin fiber mesh cover the remaining portion to cover the hole in the wall. Each wall in the plurality of walls is made of a synthetic resin film.
