A heat exchanger assembly includes a core assembly having air passages that are closed off on at least one side by a closure bar. A reinforcing bar is received within a channel of the closure bar to create an interface with substantially no gaps that may accumulate moisture within the core assembly. The prevention of moisture accumulation at the interface between the reinforcing bar and the closure bar prevents potential damage caused by freezing.

A rupturable closure for use with a flexible container that is especially suited for pouring viscous fluids such as motor oil. The closure is secured to the pouring spout or other dispensing opening of the container and retains the viscous fluid in the container as the container is brought into inverted position for pouring. Notwithstanding the ability of the closure to hold in the viscous fluid, the closure also allows the closure to breathe when the cap is removed so as to relieve small variations in pressure as the flexible container is first grasped for pouring and thereby prevent premature rupture of the closure before or as the container is inverted for pouring. Such a closure includes a membrane secured over the dispensing opening of the container. The membrane has a small primary vent orifice in the region over the dispensing opening that is sized to permit the membrane to breathe. The membrane also has three or more part lines terminating in the primary vent orifice along which the membrane parts when the flexible bottle is squeezed. The part lines extend outward from the vent orifice substantially to the periphery of the dispensing opening. Each of the part lines is interrupted by a small connecting element across the line proximate to the primary vent orifice. The primary vent orifice and the connecting elements are of a size, and the connecting elements are positioned sufficiently close to the primary vent orifice, such that the membrane will contain the viscous fluid within the container when the container is brought into inverted position for pouring, yet the connecting elements will break away and the membrane will separate along the part lines when the flexible container is squeezed, thereby enabling the viscous fluid to flow through the dispensing opening.

External power source, and system and method using such external power source, for an implantable medical device having therapeutic componentry and a secondary coil operatively coupled to the therapeutic componentry. A primary coil is capable of inductively energizing the secondary coil when externally placed in proximity of the secondary coil. A repositionable magnetic core associated with the primary coil is capable of being repositioned by a user of the external power source. An indicator is capable of providing the user with information relative to coupling between the primary coil and the secondary coil as a function of repositioning of the repositionable magnetic core.

An ultrasmooth diamond film has a thickness greater than about ten microns and an average grain size less than about 0.5 micron. The ultrasmooth diamond film of the present invention is grown using ordinary microwave plasma CVD methods, with a metal vapor source included in the reactor to produce vapor during the growth of the film. The metal vapor source may be chosen from the first row transition elements, chromium, iron, cobalt, and nickel, or from the lanthanides praseodymium, europeum, or erbium. Any metal capable of existing in the vapor phase in the presence of the hydrogen plasma, will cause formation of the ultrasmooth film of the present invention.

An optical waveguide of niobium-doped lithium tantalate single crystal has excellent low loss waveguiding properties with strong electro-optic behavior. The waveguides are made by depositing a film of niobium on a polished lithium tantalate crystal, annealing the crystal so as to diffuse the niobium into the crystal and cooling the crystal.
