Patent IT-1299563-B1 (IT)
Inventor: DOLCI GIOVANNI
IPC: A61Q11/00
Filed: 1998-07-17
Granted: 2000-03-16
Abstract: Biocompatible nanocrystalline materials based on apatite with high specific surface properties, having average size of the crystallites comprised between 0.5 and 200 nm and possible lattice deformations and/or defects, are proposed for use in the fields of dentistry and dental hygiene, in particular for the production of preparations, solutions, toothpastes and materials for the remineralisation of enamel and dentine and for the treatment of dentine hypersensitivity. The apatite-based nanostructured materials appear to possess specific physico-chemical properties connected to their nanocrystalline and defective nature, such as the remarkable surface chemical reactivity and the hygroscopicity, which allow the material to recrystallise as a result of the metastable character of the nanocrystalline system, to be used for the remineralisation of enamel and dentine. In addition, they possess the most suitable grain sizes to easily and deeply penetrate mechanically within the dentinal tubules, and also cause it to cement the internal surface thereof, both by swelling and by readily reacting with the natural tissues.

Title: Check valve for a medical infusion valve, has an elastically deformable material diaphragm acting as a fluid seal in combination with an annular valve seat, and cooperating with an axially sliding plunger
Inventor: GUALA GIANNI
IPC: A61M/
Filed: 1999-11-12
Granted: 2002-03-12
Abstract: The check valve has an axial upstream and downstream passageways (6,14), staggered and parallel with respect to each other, and an elastic material diaphragm (18) cooperating with an annular valve seat (25) for normally keeping communication between these passageways closed. The diaphragm has an end wall (18) of a cup-shaped element (17) on which a plunger (9) rests coaxially, the plunger (9) sliding between retracted inoperative, and advanced operative positions. Valve opening occurs following flexion of the diaphragm (18), which can be spontaneous due to a predetermined fluid pressure in the upstream passageway (6), or positively operated via the plunger (9).

Granted: 1999-09-01
Abstract: The invention concerns a locking device for sports footwear such as ski boots, in which a lower leg envelopment (12) is hinged to the shell (10). Said device consists of a support (20) fixed on the inner wall of the lower leg envelopment, in which there is mounted a cam (24) on which acts a rocker arm (35) which constitutes the relative complementary surface for the cam. The coupling of the cam to the rocker arm determines the skiing or walking attitude of the footwear, in relation to the rotations of the cam which are controlled by a lever (32) arranged beside it. The device thus produced is particularly compact and structurally strong and can be produced in plastics material and be fitted directly to the already assembled footwear, without requiring other operations for its utilization. <IMAGE>

Title: Method of purifying waste gases and apparatus therefor
Inventor: KUIVALAINEN REIJO
IPC: B01D53/81
Filed: 1991-02-19
Abstract: An apparatus provides purification of waste gases by adding particles of reagent and/or absorbent, which react with the pollutants in the waste gases, to the gases, and by introducing the gases into a wetting reactor for activating the reagent or absorbent contained in the gases. Gases are conveyed to at least two levels in the reactor through inlets so that a first portion of the gases is introduced into a wetting zone and a second portion of the gases below the wetting zone. A high density of particles is maintained in the wetting zone by recycling to the wetting zone particles separated from the gas above the wetting zone.
