Patent IT-1143677-B (IT)
IPC: C08J9/00
Filed: 1977-08-30
Granted: 1986-10-22
Abstract: A three-dimensional, microporous polymer cell structure has a multiplicity of essentially spherical microcells. These have a mean diameter C of 0.5 - 100 microns and are essentially uniformly distributed over the structure. Adjacent cells are connected to one another by pores. The diameter of these pores is smaller than that of the microcells. The pore size distribution corresponds to a sharpness factor S in the range from 1 - 30. The decimal logarithm of the ratio between the mean cell diameter C and the mean pore diameter P has a value in the range from 0.2 - 2.4, and the decimal logarithm of the ratio between the sharpness factor S and the mean cell diameter C has a value in the range from -1.4 to 1.0. The pores and the cells are empty, and the polymer is a synthetic thermoplastic polymer from the class consisting of homopolymers and copolymers of ethylenically unsaturated monomers, condensation polymers and oxidation polymers, or a mixture of synthetic thermoplastic polymers belonging to this class. A further three-dimensional, microporous polymer cell structure corresponds to the above-described polymer cell structure, but at least some of the cells and pores therein are filled with a liquid active ingredient. The liquid active ingredient can be a lubricant, a surfactant, a glidant, a pesticide, a plasticiser, a medicament, a propellant additive, a polish, an insect-protection agent (insecticide), a flameproofing agent, an antioxidant, an antifogging agent or a fragrance.

Title: Displacement casting machine
Inventor: VINOGRADOV VIKTOR NIKOLAEVICH
IPC: B22D/
Filed: 1982-10-08
Granted: 1988-02-04
Abstract: Displacement casting machine has on a machine bed two dies of a mould, one of them on a movable carriage for a preliminary approach of the halves.

Title: Antiinflammatory, analgesic ointment contg. indomethacin - for use over prolonged period without effect on gastric tracts
IPC: A61K/
Filed: 1978-06-23
Granted: 1987-03-04
Abstract: An antiinflammatory and analgesic ointment comprises as an active ingredient , 0.5-1.5 wt.% of indomethacin. As the carrier, 5-35% of glycol (e.g. propylene-glycol, butyleneglycol), 10-50% of lower alcohol (e.g. ethanol) and 30-55% of water are used. Further, a gel-forming agent such as carboxyvinyl polymer, haydroxyethylcellulose, methylcellulose, carboxymethylcellulose, etc. is added. To facilitate the absorption of indomethacin through skin, esters of mono- of di-carboxylic acids are incorporated. Since indomethacin is not stable under a basic condition, it is necessary toa adjust the pH of the ointment to 5.5-7.5, (6.2-6.7). The compsn. of indomethacin facilitates its use over a prolonged period without troubles on gastric tracts.

Title: High efficiency separation and movement unit
Inventor: PESTRIN BRUNO
IPC: B07B/
Filed: 1989-06-02
Granted: 1992-06-30
Abstract: The "high efficiency separation and movement unit", is a machine that unites the pneumatic transportation and the hydraulic transportation areas. The pneumatic area is made up of the centrifugal compressor and the cyclone separator. The hydraulic transportation area is made up of the pump and the cyclone separator. This unique very compact system is able to carry out four fundamental operations at once. These operations are the aspiration, the centrifugation, the separation and collection, the pumping. All of which occur at a single and confined point of the transportation system. The centrifugation separates the material being transported from the fluid. This is done by taking advantage of the system's maximum acceleration, which saves system costs, space and energy. This gives it a higher level of efficiency in cleaning and returning used carrier fluid to the environment.
