Abstract: An apparatus for separating objects, such as cherries, that are joined together by removable links, includes a collecting vessel having a water inlet and into which the objects are conveyed by means separate from the water inlet. One or more conduits extend downstream from the collecting vessel and have respective inflow mouths situated downstream of the collecting vessel. Water pumps within the conduits cause liquid to whirl about with the products taken in therewith, and pump them into the respective outflow mouths so as to eject them. The collecting vessel is a tank whose wall facing the inflow mouths has an upper edge adapted to perform as a horizontal spillway. The upper edge is situated higher than the inflow mouths, and a chute between the upper edge and the inflow mouths causes the liquid and the objects to converge towards the inflow mouths. Preferably, water ejected from the conduits is recovered and recycled.

Abstract: A bin cleaning plant includes a bin destacking and overturning station, a plurality of bin washing stations, the whole being connected to a conveyor that transfers the bins in an orderly, continuous and sequential manner through the stations; and means that sense and measure the level of dirt present in each of said bins and that modify the washing process selectively for each of said bins according to the level of dirtiness detected. Preferably, the measurement and control means are connected to optical devices oriented toward the internal surfaces of the bins, and detect the optical/luminous/chromatic image reflected from their internal surfaces. The image is converted into one or more electrical signals with representative characteristics, which signals are compared with corresponding levels selectively predetermined and previously memorized. The measuring and control means control actuators suitable to control/drive one or more of the operating parameters of the washing station.

Abstract: Microspheres, having a size lower than 1&mgr; and comprising a biocompatible polysaccharidic polymer, are prepared with a process comprising the precipitation of polymer induced by means of a supercritical antisolvent (SAS). These microspheres are used as vehicling agents or carriers in the preparation of pharmaceutical compositions administrable by oral, nasal, pulmonary, vaginal or rectal route. These microspheres can also be advantageously used as vehicling agent or carriers in the preparation of pharmaceutical compositions for the treatment of human diseases associated with genic defects, for the preparation of diagnostics and in the agro-alimentary industry.

Abstract: The present invention is drawn to a pharmaceutical composition, comprising a pharmaceutically effective amount of an acidic polysaccharide and/or a derivative thereof, a gaseous vehicle, and a pharmaceutically acceptable carrier or excipient. Said acidic polysaccharide or derivative thereof can be hyaluronic acid, a pharmaceutically acceptable salt of hyaluronic acid, a partial or total ester of hyaluronic acid with an alcohol, a partial or total intermolecular ester of hyaluronic acid, a partial or total intramolecular ester of hyaluronic acid, a cross-linked ester of hyaluronic acid, an alginic acid ester, an ester of carboxymethylcellulose, an ester of carboxymethylchitin, an ester of carboxymethyl starch, a gellan ester, a cross-linked gellan ester, a pectic acid ester, and a pectinic acid ester. The composition can contain one or more topical drugs, and can be in the form of an aerosol or liquid spray, a foam, or a dry spray.

Abstract: Processes are provided for coating the surfaces of objects with hyaluronic acid, its derivatives or other natural or semisynthetic polymers, for applications in the fields of surgery, health care and diagnostics. The processes make it possible to bind such polymers in a stable manner to the surfaces of objects made of a wide range of materials. Surfaces treated according to the processes are characterized by a high degree of wettability, and are able to inhibit the adhesion of cells or bacteria present in the biological fluids.

Abstract: The present invention is directed to a microsphere for the controlled release of a biologically active molecule which comprises a biologically active molecule and an ester of hyaluronic acid or mixtures of said esters of hyaluronic acids, and wherein said biologically active molecule is surrounded by or adhered to said ester of hyaluronic acid, and wherein said microsphere has a diameter of between 1 .mu.m to 100 .mu.m.
