Transparent outer wrappers for cigarette packets are prepared by advancing a continuous strip of overwrap material along a given feed path in a given direction, piercing a predetermined area of the strip with a series of slits spaced apart one from another and extending nominally transverse to the feed direction, and bonding a narrow ribbon to the strip along the predetermined area, aligned on at least one portion of the slits; the strip then passes under a blade shaped so as to cut a series of “U” notches spaced apart one from the next, each creating a pull tab at the end of the ribbon, before being divided ultimately into leaves by a pair of contrarotating cutter rollers equipped with respective blades. Each single leaf serves as a wrapper for a relative pack, fashioned so that when torn open by pulling the ribbon, the ribbon encounters the slit and initiates two break lines extending away from the ribbon on either side to facilitate the removal of the wrapper in its entirety.

A bandage is formed of a film layer, an adhesive applied to the film layer, and an absorbent layer connected to the film layer. The absorbent layer comprises a compressed fabric that upon saturation with liquid expands to a volume that is at least two or three times the volume of the compressed fabric. The film layer extends in at least two directions beyond edges of the absorbent layer, so that the film layer with adhesive can attach to skin around a wound with the absorbent layer covering the wound. The film layer has folded sections adjacent the absorbent layer, so that the folded sections unfold upon expansion of the compressed fabric. The expansion of the fabric layer upon contact with bodily fluids from a wound pulls the fluids and any infectious agents out of an away from the wound, thus speeding the healing process.

A z-axis is defined as an optical axis and axes perpendicular to the z-axis are defined as an x-axis and a y-axis. Multiple metal plate pieces each have multiple groove portions formed in the direction of the x-axis. An outer shape of the metal plate pieces are such that the respective cross sections of the metal plate pieces are parallel to x-z planes at given intervals of a lens along the y-axis from a lower edge to a center and from the center to an upper edge. A metal dielectric lens is formed by laminating the metal plate pieces such that the metal plate pieces are arranged parallel to the x-z planes at the given intervals. Thus a refractive index responsive to the number of the groove portions, and the width and the depth of the groove portion can be obtained. A resultant structure causes visible light to pass therethrough.

The present invention discloses a novel method for preparing and purifying 4-(6-Amino-purin-9-yl)-2(S)-hydroxy-butyric acid methyl ester. The preparation started from cheap and easily available L-malic acid, which was transformed to intermediate I after simultaneous protection of the groups of 1-carboxyl and 2-hydroxyl. The intermediate I was selectively reduced to intermediate alcohol II, whose hydroxyl group was further transformed to an easily leaving group to afford intermediate III. The intermediate III was nucleophilically substituted with adenine to afford intermediate IV. The intermediate IV was deprotected and methyl-esterified simultaneously in methanol in the presence of an acid or a base to afford crude 4-(6-Amino-purin-9-yl)-2(S)-hydroxy-butyric acid methyl ester, which was purified by recrystallization to afford the purified product. Comparing with the prior preparation methods, the present method has advantages in low cost, mild conditions, high retention of the chiral center during the reaction, high productivity, great improvement in the quality and yield of the product and great decrease in cost, and thus is suitable for the production on a large scale.
