A heat exchange unit having a plurality of chamber units, said chamber units including an inlet orifice member, an outlet orifice member, and a plurality of walls defining a chamber interior, said chamber interior having lateral walls with plurality of protrusion members. The inlet receives a heat exchange medium flowing in a first flow direction in an initial line of low. Disposed within the chamber interior is a medium directing member, having an inclined surface, diverting the heat exchange medium from the initial flow direction so that it disperses within the chamber interior, in to at least two distinct flow patterns. The chamber interior having plurality of protrusion members on lateral walls of said interior, further causing the dispersion of heat exchange medium flow, causing turbulent flow pattern within the chamber interior. The heat exchange medium exits the chamber, via the outlet, in the initial line of flow. The chambers are interconnected by tubes to form assemblies. Plurality of chambers is arranged between manifolds to complete the medium flow.

A heat exchange chamber includes an inlet, an outlet and a plurality of walls defining a chamber interior. The inlet receives a heat exchange medium flowing in a first flow direction in an initial line of flow. Disposed within the chamber interior is a medium directing member, having an inclined surface, which diverts the medium from the initial flow direction so that it disperses within the chamber interior. Exposure to the contact surfaces provided by the chamber walls causes the medium to exchange heat with the chamber and the external environment. The medium exits the chamber, via the outlet, in the initial line of flow. The chambers are interconnected by tubes to form assemblies. Plural sets of chamber and tube assemblies are arranged between manifolds to provide a heat exchanger.

A pre-loaded container and a method of manufacturing a preloaded vial is provided wherein one or more active agents is lyophilized within the vial cap and the vial cap is then sealed onto a vial retaining a suitable diluent to form the pre-loaded vial. Lyophilizing the one or more active agents within the vial cap ensures that the one or more active agents are retained in sterile conditions, that the lyophilized one or more active agents and the diluent may be stored efficiently, and that the one or more active agents may be solubilized in a sterile and efficient manner.

A screw less, adjustable cover plate for electrical fixtures is disclosed. The cover plate has a rear side which comprises of a prong attached thereto or molded as an integral part of the cover plate. The prong extends rearward from the cover plate and is orthogonal to a face of the cover plate. The prong is positioned in such a manner that it aligns with a threaded hole in the electrical outlet conventionally used to receive a screw for fastening the cover plate to the outlet. In an embodiment, the prong is configured to be pushed and not threaded into the threaded hole, in order to secure the cover plate to the electrical outlet. In this manner, the cover plate can be quickly installed without any tools and screws.

The present disclosure relates to a membrane for flue gas separation containing a crosslinked, thermally rearranged poly(benzoxazole-co-imide) copolymer prepared simply by heat-treating a membrane prepared from an o-hydroxypolyimide copolymer having carboxylic acid groups such that thermal crosslinking and thermal rearrangement occur simultaneously or a membrane for flue gas separation containing a crosslinked, thermally rearranged poly(benzoxazole-co-imide) copolymer having a benzoxazole group content of less than 80% in the polymer chain, prepared from transesterification crosslinking of an o-hydroxypolyimide copolymer having carboxylic acid groups and a diol-based compound followed by thermal rearrangement, and a method for preparing the same.In accordance with the present disclosure, a crosslinked, thermally rearranged poly(benzoxazole-co-imide) copolymer membrane for flue gas separation can be prepared simply through heat treatment without requiring a complicated process such as chemical crosslinking, UV irradiation, etc. for forming a crosslinked structure and a membrane for flue gas separation prepared therefrom exhibits superior permeability and selectivity. Also, the method is applicable to commercial-scale production because the preparation process is simple.
