Title: Method of obtaining novel lutein-based formulations
Inventor: LOPEZ ORTIZ JUAN FRANCISCO
IPC: A23L33/155
Filed: 2002-12-20
Abstract: A method of obtaining new formulations based on lutein.     The present invention describes a method of preparation of formulations of microcrystalline lutein, particularly in the form of esters, which are resistant to oxidation and are soluble in hydrophilic and/or lipophilic media. For these formulations, the esters of lutein are mixed with antioxidants, vegetable oils and/or organic solvents, and this initial mixture is submitted to various stages depending on the type of final formulation required. These formulations are suitable for direct application as colourants in the pharmaceutical, food and cosmetics fields. They can also be used as diet supplements.

Title: Alternate methods of parachute construction
Inventor: DROZD VLADIMIR
IPC: B64D17/02
Filed: 2003-08-07
Abstract: A novel parachute and method of manufacturing can be performed quickly and inexpensively. The parachute comprises a canopy having a plurality of gores with interior and exterior sides, and a pocket on the interior side of the gores formed either with folded or gathered or folded and gathered material from the gore. Preferably, each gore is fastened to adjacent gores at two spaced locations to form longitudinal apertures between gores. When the parachute is deployed some air initially passes through the apertures.  However, instead of acting as a single unit like a traditional canopy each gore initially inflates separately in the crown region. As the gores become inflated they work together to close the apertures between the gores and trap air as a single unit.
