A soft thermally insulated padded shell housing a rigid infrastructure with a series of horizontal shelves forming compartments which are vertically aligned, and includes a pair of opposing vertical and vented walls with shelve support brackets. The pair of vertical and vented walls has a paired series of mating horizontal tracks to receive horizontal slide-in shelves in a spaced vertical array. Each of the pair of tracks are horizontally aligned to form complementary ledges that receive and support the outer edges of the slide-in shelves. The shelves may be releasably attached within tracks of the side walls of the compartment, having snapping receptacles to ensure a snug fit. When the shelves are not in use as being placed within the receiving tracks, the space within the infrastructure is substantially unobstructed and can be used to store various items. Also, the infrastructure and insertable shelves are easily and conveniently removable so that the bag may be folded for storage. Narrow side compartments, immediately adjacent to the vertical, vented walls, house coolant containers. Further, the top section of the infrastructure has segmented compartments arrayed in a horizontal fashion to accommodate a variety of food supplements in pill and powder form. Separate from the rigid infrastructure, but adjoined to the soft thermal insulated padded shell, are other soft compartment housing beverage containers, fruit, silverware, and bulk protein powder storage.

A xenon arc lamp for a motion picture projector is cooled by providing the anode end of the lamp with a shroud that forms part of a support for that end of the lamp. Cooling air flows into the shroud along the support arm and enters the shroud through a slot in its side wall. The shroud provides an annular air space around the anode end of the lamp and has an annular air outlet through which the cooling air leaves as a "sheet" of laminar air flow which tends to adhere to the surface of the bulb, thereby providing precise cooling. In this way, arc instability is avoided or minimized, while lamp life is extended.
