Abstract: Stereolithography is used to fabricate directly a single-piece, missile-usable, accurate, flightweight igniter without the use of intermediate, non-operational molds or prototypes in the fabrication process. The same prototype-less, direct stereolithography can be used to produce other missile-usable parts by designing each such part to be of a single-piece configuration and by using material that is suitable for both stereolithography and functional missile application.

Abstract: In at least some embodiments, a filter comprises a filtering media. The filtering media is impregnated with chemical compounds that effectively retain water molecules and water-alcohol molecules but not alcohol molecules. The filter also comprises a liquid channeling structure, wherein the liquid channeling structure directs liquid entering an input of the filter to flow through the filtering media before exiting an output of the filter.

Abstract: A deck of cards, tiles, or similar playing pieces, real or simulated on a computer or other device, chiefly characterized by a trilateral organization comprising three independent aspects: suit, value, and color or color group. The plurality of cards representing each element of each aspect comprise approximately equal pluralities of each element of each of the other aspects. Except for auxiliary cards, each card in a single deck represents a unique combination of a single suit, a single color group, and a single value or rank. The preferred form of the invention is a series of related triadic decks of playing cards comprising three suits and three color groups (20R, 20G, 20B), nonsexist or gender-neutral picture cards (22, 24), an improved layout, and indicative card backs (32). The layout improvement typically involves additional set designation markers (16) in the two commonly vacant corners of a card face (FIG. 2A).

Abstract: Mechanism and means for enclosing a package in a wrap. The external dimensions of the package are first determined and sufficient wrap is fed with which to enclose the package. Depending on the external dimensions of the package, the amount of wrap fed is adjusted and thereafter the package is enclosed in the wrap.
