Abstract: A storm water inlet filter system is disclosed which comprises at least two, but preferably three, distinct filter layers. The storm water inlet filter system uses a nested basket structure in which one filter basket fits within another. Preferably a piece of disposable filter media is placed within the internal basket. Polluted water flows first into the inner basket, and onto the disposable filter media. Overflowing water passes into the outermost basket which can remove debris. The storm water inlet filter system can be used with many existing drainage systems, and can be cleaned and the disposable filter media replaced without the use of specialized equipment or training.

Abstract: The invention comprises the following elements: cervico-anatomical orientation posts (FIGS. 1-8) used in the first surgical operation, in order to help replace the dental pieces to be restored; cervico-anatomical temporal healing pillars, of the direct or indirect type (FIGS. 9-12) whose design is intended to provide the gingival tissues with the morphology necessary in the healing phase and the ideal housing for the artificial tooth. Transporter (FIGS. 13 and 14), this being the element which evaluates the orientation, depth and inclination of the implants; direct and indirect cervico-anatomical transfer pins (FIGS. 16-18), which copy the exact intraoral position of the implants and the peri-implantory soft tissues; parallelizer (FIGS. 19 and 20) which replicate the position of the polygonal head of the implant; hexagonal base (FIGS. 23 and 24) for angle pillars; surgical guides (FIGS. 25-36) presenting the directing piece, patterns, tubular parts for bone drilling and direction posts.
