Abstract: The present invention relates to maskless photolithography using a patterned light generator for creating 2-D and 3-D patterns on objects using etching and deposition techniques. In an embodiment, the patterned light generator uses a micromirror array to direct pattern light on a target object. In an alternate embodiment, the patterned light generator uses a plasma display device to generate and direct patterned light onto a target object. Specifically, the invention provides a maskless photolithography system and method for photo stimulated etching of objects in a liquid solution, patterning glass, and photoselective metal deposition. For photo stimulated etching of objects in a liquid solution, the invention provides a system and method for immersing a substrate in an etchant solution, exposing the immersed substrate to patterned light, and etching the substrate according to the pattern of incident light.

Abstract: A match package includes a synthetic resin core in combination with cover members sandwiching the core to define a space of uniform height. The core includes partition walls dividing the space into oblong compartments. The walls are joined at one end to block those ends of the compartments and at the other end are joined by floors which reduce the height of the space in each compartment. The head of a match is positioned at the blocked end of the compartment and its free end projects from the other, open end. Striking material on the cover portions which oppose the floors frictionally engage a match head to ignite same in response to axial withdrawal of a match from its compartment.

Abstract: A refillable matchbook holder having open and closed positions. The holder comprises a single strip of flexible material folded into four segments. Two of the segments are provided with slots for securing matchbooks to the strips, the other two segments being provided with windows permitting access to the match-striking surface of matchbooks. In its closed position, the holder and attached matchbooks form a compact match case, with the two matchbooks facing each other and oriented top to bottom.

Abstract: A plastic holder for safety matches or bookmatches which completely enfolds a typical pack of bookmatches and locks in such a manner that it is difficult for children to open and gain access to the matches. The plastic holder is formed with a pouch to receive the pack of matches which exposes the striker area on the pack when the holder is open. The holder requires a squeezing-twisting motion in order to lock the holder around the pack of matches and a reverse motion of twisting and squeezing is required in order to open the holder.

Abstract: A match book safety case having a back and a front hinged together for enclosing a book of matches. The case presents an opening so that the striker portion of the book itself is exposed when the case is closed; and the case has a safety device which automatically covers the book striker portion when the cover is open, and therefore the user cannot strike a match until the cover is closed.
