Title: Method for limiting a woodland fire and devices for implementing that method
IPC: A62C/
Filed: 1992-03-31
Granted: 1996-04-29
Abstract: A method for restricting a woodland fire and devices for implementing the method are described. The method is designed to provide a strip of land which inhibits flame propagation through laying a plurality of uniformly distributed explosive charges of equal size along the sides of a strip of land which is intended to prevent the propagation of flame and priming of the charges by means of a detonator. Subsequently there is explosion of the charges with the formation of high pressure such as to cause ordered and systematic dispersion of the bushes, trees, shrubs and others present in this strip. The method also comprises the laying of a number of explosive charges substantially along the axis of the longitudinal centre of the strip of land, priming these and explosion of the charges with the formation of turbulence such as to cause orderly and systematic dispersion of fire- preventing material located about the set of charges which will cover the strip and a strip of vegetation on the sides of the said strip. <IMAGE>

Title: Procedimento per la realizzazione di protesi tessili, ad esempio protesi vascolari, e protesi tessile ottenibile con tale procedimento
Inventor: BONA GIOACHINO
IPC: A61F2/06
Filed: 1992-08-06
Granted: 1995-12-27
Abstract: La protesi viene ottenuta intrecciando un filo di fondo (1) ed almeno un filo di effetto (2). Il filo di fondo (1) presenta un elevato grado di termoretraibilità mentre il filo di effetto (2) è sostanzialmente termostabile. L'intreccio così ottenuto viene quindi riscaldato, ad esempio per immersione in acqua bollente, così da determinare un restringimento del filo di fondo (1), con conseguente riduzione della permeabilità ai liquidi. Il restringimento non interessa in misura apprezzabile il filo di effetto (2). E' quindi possibile ottenere buoni effetti di vellutatura senza ricorrere al tasso di sovralimentazione del filo di effetto (2) molto elevati.(Figura 4).
