Abstract: In a method for producing a PBO fiber with increased resistance against UV-caused degradation, a coating is provided on the PBO fibers, wherein the coating comprises graphene oxide cross-linked by polymerization with glutaraldehyde and resorcinol. The fibers are useful for lighter than air vehicles.

Abstract: A lithium sulfur battery with a low solvating electrolyte at an amount of less than 2 ?l per mg sulfur. The electrolyte comprises dioxolane and hexylmethylether, as well as a Li salt, for example LiTSFi. The electrolyte is free from lithium nitrate, LiNO3.

Abstract: Disclosed is a water dispenser including a container with an out-let channel at the bottom thereof and a manually operated valve arrangement with a valve member resiliently pre-stressed towards a closing state.

Abstract: Disclosed is a water filtration device which includes various hoses for connection between different parts of the filtration device and a rotatable cam system which, during backwash cycles, is rotated so as to clamp various the hoses in predetermined sequences for thereby controlling the direction of the flow of water through the tubing system. Electrical pinch valves are use alternatively to a cam shaft.

Abstract: A lighter than air airship (1) comprising a gas-filled flexible hull (2) which is elongate with a longitudinal axis (1?) and with a front end (4) and a rear end (5), wherein a harness-structure (3) is abutting an outer side of the hull (2) and not perturbing the hull and not extending through the hull, the harness-structure (3) is made of a bendable material and carries a propeller engine (10) for forward thrust of the airship (1), rechargeable batteries (11) for providing electrical power to the propeller engine (10), and a solar panel for providing electrical power to recharge the batteries (11).
