The present disclosure relates to automotive heat exchanger assemblies that may withstand high environmental temperature and pressures conditions. By providing a tube strengthener into the tubes at the areas of highest stress, the heat exchanger assembly may be strengthened so that it is substantially more efficient under typical operating conditions.

The present invention relates to automotive heat exchanger assemblies that can withstand high environmental temperature and pressures conditions. By providing a tube strengthener inserted into the tubes at the areas of highest stress, the heat exchanger assembly is strengthened to be efficient under typical operating conditions.

In one embodiment, the container/dispenser for an ultra high purity chemical includes a thin walled inner container made of TEFLON polymer. The thin walled inner container is closed at the top by an inner container lid. An outer container surrounds the inner container and comprises a metal outer wall that is interiorly covered or lined with TEFLON polymer or other polymeric material. The outer container is closed at the top by an outer container lid. The inner container is separated from the outer container by a spacer assembly that spaces the side and bottom walls of the inner thin walled container away from the inteiror surface of the outer container. An inert gas is disposed in the interspace between the inner and outer container and a set of valves are mounted on the inner and outer container lids. One valve allows an inert gas to be bubbled through the ultra high purity chemical while another valve dispenses the 'bubbled' chemical. Third and fourth valves permit injection and extraction of the inert gas from the interspace between the inner and outer containers. The method of storing and dispensing includes the steps of containing the ultra high purity chemical in a thin walled TEFLON polymer inner container, surrounding the entirety of the inner container with an inert gas, providing an outer container and enclosing the inner gas and the surrounding inert gas with the outer container.

Reusable container dispenser for ultra high purity chemicals and method

An apparatus for relieving static subterranean water heads surrounding subterranean walls which includes a perforated hollow sleeve arranged to extend through the subterranean wall and into a surrounding static water head. The sleeve has distal and proximal ends, with a plurality of spaced perforations being formed in the wall of the sleeve substantially along the length thereof. The distal end is tapered substantially to a pointed tip, and the tapered tip portion is of generally solid construction. A flanged coupling means is formed adjacent the proximal end for coupling water conduits internally thereof. When desirable, an imperforate sleeve means may be provided adjacent the proximal end for rendering a portion of the perforated hollow sleeve adjacent the proximal end substantially watertight, thereby protecting paneling which may be pre-positioned in the subterranean wall.
