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.

Bonding apparatus and bonding method

The bonding apparatus of the present invention is an apparatus that bonds a patch containing a reinforcing fiber to a bonded section of a corner section CR of an object member. The bonding apparatus has s heater mat, a pushing member, a bag member having a decompression port, a mold releasing film, a breather, a heater mat and a sealant. A pushing member has a first cowl plate, a second cowl plate and an elastic pressuring body. A pressuring section of the pushing member has the surface shape corresponding to a corner section design value after the patch is bonded. By protruding from a gap between a first cowl plate and a second cowl plate to a direction of the corner section CR, the patch is pushed to the bonded section and the generation of a wrinkle in the reinforcing fiber can be prevented.

The present invention further relates to an arrangement (17, 17, 17) for portion-packing of an oral pouched snuff product.

Tendon placement for high-altitude balloons
10406756 · 2019-09-10 · ·

Aspects of the disclosure relate to manufacturing balloon envelopes for use in high-altitude mesh networks for packet-data communications. As an example, a gore portion may be placed on a table such that the gore portion overlies a groove within the table. A tendon may be placed on the gore portion and within the groove. A portion of tubing may be placed over the tendon. The tubing may have one or more surface openings. Restraining tape is applied over the one or more surface openings in the tubing. A constant force roller is applied to secure the tendon to the gore portion and to secure the tendon to the tubing. As an alternative or in addition to the surface openings, double-sided restraining tape may be placed between the tendon and the tubing. The tubing and restraining tape may prevent undesired lateral and longitudinal movement of the tendon during deployment.
