Title: Procedimiento de obtención de un fertilizante granulado a partir de roca fosfórica parcialmente acidulada
Inventor: VELOZ MADRAZO YANELIS
IPC: C05B11/08
Filed: 1997-11-07
Abstract: Con el objetivo de ofrecer un producto con buenas propiedades físico-mecánicas se granulan la roca fosfórica empleando ácido sulfúrico concentrado (96% mínimo) con el objetivo de solubilizar el P2O5 presente en el mineral en presencia de solución amoniacal (18-25% de nitrógeno) e incorporando a la mezcla zeolita (en cantidades entre 5-25%). La relación ácido sulfúrico / roca fosfórica oscila entre 0.5-1 del valor estequiométrico. En el producto obtenido se solubiliza entre un 40-50% del fósforo de forma inmediata, aporta además cantidades de Nitrógeno, Azufre, Calcio, Silicio y Hierro, entre otros componentes de interés para la agricultura. En comparación con la roca parcialmente acidulada tradicional este producto presenta las siguientes ventajas pues actúa además como: - Acondicionador de suelos erosionados, salinizados y ácidos. - Regulador del pH. - Mejorador de las condiciones físicas del terreno aumentando el coeficiente de utilización de los nutrientes, lo que incrementa los rendimientos agrícolas. Además: - En los suelos salinos favorece el intercambio Sodio-Calcio. - Mejora la utilización del nitrógeno impidiendo sus perdidas por volatilización y lo libera según lo requiera la planta. Asimismo la presencia de nitrógeno favorece la asimilación del fósforo en el suelo. - Evita el endurecimiento de los fertilizantes y disminuye las perdidas de los mismos por agua superficial.

Patent WO-03032513-A1 (WO)
Inventor: RUPRICH THOMAS
IPC: H04B1/707
Filed: 2002-07-24
Abstract: The invention relates to a method for carrying out the joint detection (JD) equalization of a received signal that returns to the superimposition of a number of spread-coded subscriber signals. In a first step, a set of equalizer coefficients for the k-ten subscriber is calculated by solving for an inhomogeneous linear system of equations whose coefficient matrix is based on the received signal. This involves the use of an iterative solving method. In a second step, the received signal is equalized while using the calculated equalizer coefficient set for the k-ten subscriber.

Title: Fuel loading facility - for pressurised water reactor incorporating loading channel and storage bay
Inventor: WEBER ROBERT
IPC: G21F5/08
Filed: 1972-10-30
Abstract: Reactor plant layout particularly applicable to pressurised water reactors in which sae handling fuel is enhanced by a water filled vertical loading channel inter-connected to the fuel storage bay.
