Patent IT-1227922-B (IT)
Inventor: MILONE CARMINE
IPC: G02C5/16
Filed: 1988-11-18
Granted: 1991-05-14
Abstract: The present invention concerns a bar for spectacles formed in two parts of relatively stiff plastic material, joined together by means of an elastic springing element in the form of a spiral spring. According to the invention, said elastic element also comprises a flat spring with surface positioned on a vertical plane, said spiral spring being wound in tight coils around a central part of said flat spring and being checked on opposite sides by two stop rings, the end parts of said flat spring forming means of anchorage into the two bar portions of plastic material. The invention also concerns a method for manufacturing said bars for spectacles, wherein said end parts of the flat spring of the elastic element are enclosed into a respective box of an injection mold, using said stop rings of the elastic element to delimit and close the mold, plastic material being then injected into said boxes to incorporate said end parts of the flat spring.

Title: Oxidn of ethylene to acetaldehyde - in aq catalyst soln contg cupric chloro-acetate, palladium salt and acetic acid
IPC: C07C/
Filed: 1975-05-06
Granted: 1979-11-20
Abstract: In the prepn. of acetaldehyde (I) by direct catalytic liq phase oxidn. of ethylene (II) in presence of O2 in an aq. soln contg. Pd, Cu salt and acetic acid, the catalyst soln. contains CuCl(CH3COO) (III) opt. mixed with CuCl2. Pref. the soln. contains 0.001-0.015 mol/l Pd. Salt; 0.3-1.2 mole/l (III) (or 0.25 - 1.15 mole/l (III) plus 0.05-0.5 mole/l CuCl2) and 15-30 wt. % acetic acid. Oxidn. and catalyst regeneration occur in a single zone and rate of circulation of catalyst soln. can be increased from 5-6 to 16-18 kg/m3/hr. Selectivity is improved with redn. in content of Cl-contg. byprods. from 2-3 to 0.6%. Cu content in the catalyst soln. is 2-3 times lower than conventional soln. and, since O2 and (II) conversions are almost 100%, gas recycle is unnecessary.

Title: Adhesive fastener for repeated resealing
Inventor: CLERICI PIERO RUSCONI
IPC: C09J/
Filed: 1982-12-20
Granted: 1987-01-21
Abstract: Adhesive device consists of a part which will adhere selectively to another identical or similar part so that the two can be repeatedly sepd. and rejoined. Each part consists of at least one adhesive layer of elastomer (pref. a mixt. of 80-85 wt.% natural rubber and 15-20 wt.% butadiene-styrene rubber, dry wt.) on a substrate, the strength of the substrate and the adhesion between the substrate and the elastomer being greater than the adhesion between two elastomer layers. The elastomer layer has a smooth surface and is less than 1mm thick. It may be vulcanised, but not to the extent that it loses its adhesivity. The degree of vulcanisation may vary through the thickness of the layer, being greater nearer the substrate, and the most highly vulcanised part may itself constitute the substrate. Unlike adhesive tapes, the device sticks only to itself and is not affected by dust and moisture in the atmosphere. Two parts of the device can easily be separated and will not form a permanent bond over a long period.

Granted: 1992-09-09
Abstract: The machine for the processing of precious and semiprecious stones is made up of a base, a pillar on which an electric motor is placed, a tool turret with three degrees of freedom. This turret moves to and from the disks, whish are put in motion by the motor via a ram on calibrated rollers. They are moved to and from the centre of the disk by the oscillation of a bushed bearing around the bearing axle, and cause a radial shift in respect to the disks via the oscillation along a group of splitters for the faceting of the stones.

Title: Hydrometallurgic process for the recovery, the purification and the reuse of platinum, palladium and gold by the use of activated carbons
Inventor: BARONCELLI FRANCO
IPC: C22B/
Filed: 1990-11-16
Granted: 1994-07-28
Abstract: Hydrometallurgic process for the recovery of precious metals from any low content source (minerals, catalysts, residues from industrial processing, wastes, scrap, and the like) based on the use of activated carbons. The process allows the concentration and purification from extraneous elements and the total recovery of the elements Au, Pt, Pd from acidic solutions derived from the attack of materials soluble in aqua regia. The process is classifiable under the name "hydrometallurgic" because it avoids the alternative, high energy-cost, processes which use high temperatures (pyrometallurgic processes), and allows a recovery of precious metals greater than 99%, with an impurities content less than 0.1%. <IMAGE>
Patent IT-1116522-B (IT)
Title: Multistation reaction injection moulding appts. - in which each station is fed with components via a supply and a return manifold
IPC: F25D/
Filed: 1979-03-29
Granted: 1986-02-10
Abstract: In apparatus for reaction injection plastics material at separate stations, each of the components is fed from a source along a supply manifold and back to the source via a return manifold. Each station has a mixer/injector head connected via feed and return shunt lines to the supply and return manifolds. First valves are provided to stop circulation in the manifolds and second valves are provided to prevent circulation of components from the manifolds to the heads. In use, to effect injection with a chosen head the first valves are closed to prevent manifold recirculation and the second valves of all the heads except the chosen one are closed. This causes the components to flow along the supply manifold and down the shunt line of the chosen head for dispensing. The arrangement is of particular use in injecting foamed resin, e.g. polyurethane, into refrigerator cabinets fed from a main conveyor to positions beneath the heads. One or more heads can be used at the same time.

Title: Grouting of fissured concrete or masonry faces - using sealed surface cover with tubular edge bead to apply vacuum and then inject grout
IPC: E04B/
Filed: 1977-08-31
Granted: 1985-05-25
Abstract: The process may be used to grout fissured or impaired concrete or masonry surfaces, and uses a temporary impervious surface cover to apply vacuum and finally insert grout. The cover (1) has a continuous tubular edging (2) and is stretched tightly over the subject surface (R). The edges (5) of the cover are then sealed, air or other fluid is evacuated from within the cover and the fissures of the subject surface, and finally the grout is injected. The edging tube (2) may be of semi-circular cross-section, may be used as the medium for evacuation. It may be a separate component which is sealed independently onto the surface and the cover. Grout injection may be effected through an inlet (4) in the main cover (1) body.

Title: Selective recovery process for chrome present in the solid residues from tannery procedures, and the use of the organic de-chromed material for the production of fertilizers, gelatine glues and protein products
Inventor: MANZINI MASSIMILIANO
IPC: C22B/
Filed: 1989-12-18
Granted: 1993-04-22
Abstract: A process conceived to resolve the problem that the tanning industry has to face: the treatment of the chromium residues from tanning, which are presently stockpiled, or are used as fertilizers, with consequent, and not to be overlooked, environmental degradation; it is enough to think, that leather shaving alone, which produces shavings, filaments and cuttings, as a result of the cleaning of leather already tanned, makes up about 1/3 of the total amount of tannery waste, and contains on the average, 2.5% chrome. We are faced with a considerable environmental problem, as well as with an enormous waste of products, which are presently destroyed and create pollution damage.

Filed: 2021-04-22
Abstract: The present invention discloses a composition of bread comprising supercritical carbon dioxide defatted sea buckthorn berry pomace, in order to improve the nutritional value of the bread - antioxidant potential and dietary fiber content. In this way, during the mixing of the dough, from 1 % to 5 % of the flour is replaced by supercritical carbon dioxide defatted sea buckthorn berry pomace, which is prepared by drying freshly pressed sea buckthorn berries at a temperature of 40 to 50 °C until the residual moisture content does not exceed 10 %, grinding to approx. 0.5 mm particle size and defatting by extraction with supercritical CO2 at a pressure of 35-40 MPa, at a temperature of 45-50 °C, for 4 hours. According to the best variants of the composition, in which 2.5 and 5 % of the flour is replaced by defatted sea buckthorn pulp, the total content of phenolic compounds increases 10 and 11 times, the oxygen radical absorption capacity 5 and 21 times, the content of dietary fiber 2.08 and 2.85, respectively. Other physicochemical parameters change insignificantly.
