Abstract: La présente invention fournit un moyen d'appliquer numériquement la modulation d'amplitude et de phase et directement à une fréquence RF qui bénéficie de la puissance de sortie élevée en utilisant des amplificateurs non linéaires. Ceci est accompli par la combinaison de deux vecteurs variables à phase et amplitude constantes. Un oscillateur de référence produit un signal de porteuse, qui est fourni à deux lignes à retard numériques composées d'une séquence de banques à retard. Les lignes à retard sont commandées par des tables de consultation qui sont mises à jour par le circuit de commande vectoriel utilisé pour déterminer le retard sur chaque ligne à retard numérique. Le retard des lignes est fixé de manière à produire deux vecteurs avec le déphasage souhaité qui, lorsqu'on les additionne, produit un vecteur ayant les caractéristiques souhaitées de phase et d'amplitude.

Abstract: A track assembly having first and second hub assemblies that are operatively connected to a support frame by first and second attachment members, respectively. The first and second attachment members include resilient or movable mounts that are configured so that the track assembly can be attached to vehicles whose axles or wheel flanges are misaligned or have irregular rotational movement such as runout or wobble. The attachment members may be adjustably positioned relative to the support frame to accommodate vehicles having different wheelbase lengths and axle lengths. An endless track encircles the first and second hub assemblies, and the support frame, and is drivingly engaged by one of the hub assemblies. First and second rollers, which define the longitudinal extent of the endless track, are positioned at either end of the support frame. A tensioning member, with at least one upper idler roller, positions the endless track so that it is spaced from one of the hub assemblies in a spaced relation. The track assembly increases traction and stability by providing a vehicle with an independent front suspension, a larger footprint, and a longer wheelbase. In use, each track assembly is bolted onto wheel flanges of a vehicle using existing wheel lugs and nuts.

Granted: 2008-02-12
Abstract: A method for producing ethanol starting from corn flours, which provides for the milling of the corn, the separation of the light fractions (bran), a first refining of the milled fractions, a first sifting with germ separation, a second refining of the milled fractions, and a second sifting with germ separation. In particular, according to the invention, impact milling of the wet corn is provided so as to preserve the largest possible average particle size of the milled fractions, and subsequent crushing of the germ is also provided, so as to facilitate size separation thereof. With respect to known systems for producing ethanol starting from corn flours, the method according to the invention allows to extract from corn at least 7%, preferably at least 10% (by weight with respect to the initial product) of pure germ (i.e., germ not contaminated by other components) and at least 1% pure bran, preferably at least 2.5%, before transfer to the ethanol extraction plant, with the previously cited consequent advantages and overcoming the drawbacks that arise from using the systems that constitute the background art. In particular, the extraction from corn of at least 7% of the germ, preferably at least 10%, and of at least to bran, preferably at least 2.5%, allows to achieve drastic reductions in the production of pasty residues in the subsequent ethanol extraction process.
