A module and an apparatus incorporating such module utilizing a plurality of tubular membrane elements, each configured to separate oxygen from an oxygen containing feed stream when an electric potential difference is applied to induce oxygen ion transport in an electrolyte thereof. The tubular membrane elements can be arranged in a bundle that is held in place by end insulating members. The insulating members can be positioned within opposed openings of end walls of a heated enclosure and can incorporate bores to allow an oxygen containing feed stream to flow past exposed ends of the tubular membrane elements for cooling the end seals of such elements. Further, first and second manifolds can be provided in a module in accordance with the present invention to collect separated oxygen from two separate portions of the tubular membrane elements.

Oxygen separation module and apparatus

An adhesive composition that bonds at low temperatures is disclosed. The composition is a solution in an organic solvent of a polyimide, an epoxy resin, and a cyanate. The polyimide can be a polyimidesiloxane, made from a dianhydride, an aromatic diamine that does not contain siloxane, and a siloxane diamine. The adhesive composition can be used to make a single layer tape, a coated tape, or a double-sided trilayer tape. The tape can bond an article, such as a chip, to a substrate, such as a circuit board.
