Abstract: The present invention provides processes for the production of polysaccharides containing the L-iduronate subunit, for example, heparin-type polysaccharides. New intermediate compounds and processes developed during the production of said polysaccharides are also presented.

Abstract: Cutting apparatus and methods are provided for cutting and trimming of flat materials, the invention incorporating an optical guide means for positioning of the flat material in a desired orientation. A laser device is positioned on a cutter to project a visual indication of the line of cut to be made by the cutting blade, and optionally along other lines such as to show a border or margin. Means are provided to power the laser device, and an optical element is provided to focus an emitted beam onto the cutter base, and any material placed thereon. Additionally the cutter includes a switching means for turning the laser device on and off. The switch can be mounted anywhere on the base or the cutting assembly. The cutter includes a cutting base for supporting the materials to be cut, a cutting blade assembly, and assistive cutting means such as a bottom blade on one edge of the base or a pad cooperating with the cutting blade to cut the flat material.

Abstract: The invention relates to benzoic acid derivatives being leukotriene antagonists. The compounds therefore are suitable as active ingredients in medicaments particularly in medicaments for the treatment of respiratory diseases.

Abstract: A chimney cap for diverting rain and downdrafts from a chimney while providing minimal restriction to the upward escape of chimney gases includes a base, for attachment to the chimney, and two arch-like sheet metal members attached to the base. The arches are of different heights and overlap one another over the center of the base to form a clearance therebetween for the escape of gases. The crowns of the arches are inclined in opposite directions and slope downward from the center of the cap to overlie opposite sides of the base.
