Abstract: There has been provided a delivery system for conditioning molten thermo-plastic material, wherein a first pipe member, having an inlet at one end adapted to receive the material and an outlet at an opposite end for delivering the material therefrom at a desired homogeneity is coupled at its inlet end to a furnace. An insulated shell structure, having at least one fluid inlet and outlet therein, is located concentrically about the first pipe member and defines a closed insulated space thereabout. The shell is adapted to receive heat exchange fluid for circulation from the inlet to the outlet in said closed space for removing heat from the thermo-plastic material flowing through the pipe member. Means is provided for shielding inside surfaces of space between the shell and the pipe member from deleterious ambient including a purge fluid which may act alone as the heat exchange fluid.

Abstract: Certain portions of the discharge slots of an existing extrusion die for forming honeycomb structures are blocked off by selectively positioning a plurality of tabs within such discharge slots so as to convert the cellular configuration originally formed by the discharge slots of such die to that of a desired cellular configuration.

Abstract: A ceramic honeycomb structure having cells which deform in a preinduced manner under stress is disclosed. Each of the cells is formed by interconnected convexly and concavely curved partitions, the cross-sectional profile of each of the curved partitions preferably being a half sine wave. Thermally induced stresses exerted in planes normal to the honeycomb axis will cause the concave partitions to bow inwardly and the convex partitions to bow outwardly, whereby the corner angles between partitions will remain generally equal to their original values.

Abstract: In a flat panel display system including an enclosing housing structure having opposed front and back panels connected together by a plurality of hermetically sealed sidewall panels, which structure requires a subatmospheric or evacuated environment for the performance of the components contained therein resulting in the production of undesirable stresses in the opposed panels due to the forces generated by atmospheric pressure, the sidewall panels are formed with oblique panel portions lying skew to the opposed front and back panels and extending outwardly of the housing intermediate said opposed panels, and thereby reduce the maximum stresses generated in such front and back panels to within acceptable limits. The skew panels may be formed of glass and be of uniform thickness along their extent, or may be contoured so as to taper in thickness toward a center portion intermediate the front and back panels.

Abstract: A cell for generating electric energy is provided comprising a sealed container partitioned into anode and cathode chambers, said partition comprising an electrolyte/separator in the form of a bundle of hollow glass or ceramic fibers, fusion sealed together between their interstices adjacent at least one end thereof. Preferably, the ends of the fibers which project within the anode chamber are sealed closed whereas the opposite ends are in open communication with the cathode chamber. Preferred anode and cathode materials comprise an alkali metal such as sodium or potassium and sulfur respectively.

Abstract: In a flat panel display system including a polyhedral enclosing housing structure having opposed front and back panels, which structure requires a subatmospheric or evacuated environment for the performance of the electronic components contained therein, a plurality of substantially parallel transversely spaced apart and longitudinally extending supporting vanes are fixtured within said housing between said front and back panels for limited movement within said housing prior to evacuating the interior thereof and for engagably supporting said front and back panels against the forces generated by atmospheric pressure when said interior is evacuated.
