Patent IT-1169963-B (IT)
Inventor: ADORJAN ANDRAS
IPC: A61M5/315
Filed: 1983-12-09
Granted: 1987-06-03
Abstract: PCT No. PCT/HU83/00060 Sec. 371 Date Aug. 6, 1984 Sec. 102(e) Date Aug. 6, 1984 PCT Filed Dec. 5, 1983 PCT Pub. No. WO84/02278 PCT Pub. Date Jun. 21, 1984.Disposable syringe made of plastics, for medical purposes, consisting of a barrel (1), a piston (2) provided with a plunger shaft (3) guided at a distance from the barrel wall, and a closure cap (4), the piston (2) being releasably joined to the plunger shaft (3). The piston (2) is at least partially softly resilient due to the fact that on the piston periphery wall parts of greatly reduced wall thickness are present. The closure cap (4) contains a sufficiently long, stable slide bearing for the plunger shaft (3), so that deformation of the latter, arising out of off-center application of force in the retracted piston position, and out of the tendency of the relatively thin plunger shaft (3) to bow or buckle, will not be transferred to the piston (2).

Title: Optical fibre splice alignment guide - is formed with curved sides by pulling two touching heated glass rods
IPC: G02B/
Filed: 1979-07-31
Granted: 1990-12-27
Abstract: The optical splice having a V-groove alignment guide for butting together the ends of two optical fibres is formed by placing two glass rods together with axes parallel and surfaces touching and pulling the rods while they are heated. This produces a V-guide with curved surfaces when circular rods are used. Straight-sided V-grooves may be made by using rods of triangular or quadrilateral cross-section. Two to four rods may be used and the guide formed from the fused rods may be secured to the inside surface of a tube.
Patent IT-1044841-B (IT)
Title: Composite reflective elements - formed by setting small balls in a resinous surface
IPC: G02B/
Filed: 1972-06-17
Granted: 1980-04-21
Abstract: In making composite reflective elements consisting of a principal transparent body which receives and refracts light so that it is focused through a spherical surface onto a reflecting surface, the transparent body is coated with a transparent layer of plastic capable of remaining soft at a low temp. but gelling rapidly at 100 degrees C and is treated with small balls preheated to 100 degrees C. which initiate local gelling so that when the surface is completely covered the resin has polymerised. The method is suitable for forming spherical surfaces with a coating of small balls, or by detaching them, surfaces backed with spherical imprints which can be reflectively coated. The principal transparent body is pref. a sphere of a lenticular shape. The plastic coating layer is pref. a polyisocyanate mixed with a polyester contg. free OH gps. together with an amine accelerator. The small balls may be precoated with a release agent. After removal of the balls the spherical imprints may be coated with a reflective layer out may also first receive a meniscus of solidified liquid resin.

Title: System for the manufacture of insulating panels and the respective panels
Inventor: TONELLO ROMEO
IPC: E04D/
Filed: 1990-03-20
Granted: 1993-09-03
Abstract: The invention concerns a machine for the manufacture of flat or curved sandwich panels for the thermal insulation of buildings. The insulating layer, which is made of polystyrene, is injected directly between two flat or curved metal and/or plastic sheets. This invention refers to the covering panels for buildings and in particular panels for curved or flat walls and roofing. At present, in the buildings to be insulated, panels are used with polyurethane foam injected into the gaps, or polystyrene panels are used.
Patent IT-1206672-B (IT)
Title: Warp knitter yarn feed - with roller pair connected to drive of cross guide unit through a gearing and freewheel to eliminate yarn store
IPC: D04B/
Filed: 1978-03-28
Granted: 1989-04-27
Abstract: The feed of yarns, film or other strip material to a warp knitter uses a reciprocating cross guide unit and a pair of rollers to move the material. A guide roller deflects the yarn, film or other strip material so that it is guided parallel to the movement of the cross guide. The drive to the roller pair is connected to the drive for the cross guide unit through a gearing and freewheel so that the rollers are only powwered during the away movement of the cross guide unit. The system provides a positive feed action for the yarn or film strip material, without requiring a store unit in the material feed path to the warp knitter.
Patent IT-1069068-B (IT)
Title: Grain oriented silicon steel annealing separator - based on magnesium oxide and contg. rare earth oxides or metal silicates
Inventor: MARIANESCHI EDMONDO
IPC: C21D/
Filed: 1976-05-24
Granted: 1985-03-25
Abstract: An annealing separator for grain oriented Si steel sheets based on MgO contains in addn. oxides of rare earth metals, cpds. of rare earth metals which thermally decompose to oxides, or silicates. The separator economically improves the annealing operation and also improves the magnetic and electrical properties of the sheet. The surface of the annealed sheet has cavities contg. a glass film which affects the roughness and the resistivity. Rates of denitriding and desulphurisation are increased. The adhesion of vitreous films to the sheet is also increased. By reducing the roughness the drawability is improved, leading to improved magnetic properties. The final annealing time is reduced. In certain cases the additional insulating glass can be eliminated. There is also fewer problems when mechanically treating the sheet.

Abstract: Water-soluble polyurethanes and their prepn. by reaction of (A) an anionic sulphonated polyester with average mol. wt. 500-3000, acid valve below 20 mg KOH/g., and S content 0.8-2 wt. %, with (B) >=1 diisocyanate, at 130-230 degrees C in molar ratio of NCO/OH+COOH 1. The opds. are used as sizes for textiles, esp. warp yarns in weaving, and for re-sticking the grain and flesh sides of leather. The polyurethanes dissolve readily in cold water to give stable solns. They are esp. suitable for sizing synthetic yarns, and do not dirty or block up the looms.

Title: Piston sleeve coupling for radial piston pump - has spring loaded piston terminating in enlarged spherical section socket
IPC: F04B/
Filed: 1975-02-12
Granted: 1979-03-30
Abstract: A spring-loaded piston and a socket-type sleeve are adapted to receive the piston in a high-pressure radial piston pump. The piston terminates at a rear end in an enlarged spherical section that defines a volume smaller than a hemisphere. The socket member includes a spherical recess that receives the spherical section of the piston, and a surrounding edge region that is crimped inwardly at diametrically opposite portions to define a plane of oscillation of the sleeve member w.r.t. the piston and to capture the spherical member in the sleeve. To retain the coupling parts in operative association with each other, an external abutment ring is pressed over the piston adjacent the spherical section. The abutment ring extends radially outward to contact the front end of the sleeve member when the sleeve has oscillated through a limited predetermined angle w.r.t. the piston.

Abstract: Descreve-se um dispositivo de imobilização
interdental que consiste numa fixação de pelo menos dois
componentes, um elemento de parafuso, e uma porca, ou como
uma fixação de 3 ou 4 peças que emprega um cone com uma
abertura desde a base até ao bértice de modo a que o parafuso
pode passar através dele, tendo o parafuso uma haste
helicoidal roscada que se une por enroscamento com a porca.
O parafuso e o cone têm meios para ancorar o parafuso ao
cone. O cone é passado sobre o parafuso e ancorado no mesmo;
e o parafuso é impelido através dele a partir do interior
da boca, através da gengiva e entre dentes adjacentes,
e depois engatado sobre a porca roscada, pelo que o elemento
de fixação fica seguro entre dois dentes adjacentes.
Utilizando uma pluralidade destas duas fixações de 3 ou 4
peças, alternadas e espaçadamente dispostas ao longo tanto
do maxilar superior como do maxilar inferior, quando estes
estão interligados com arame ou elástico, o maxilar inferior
fica efectivamente imobilizado ao maxilar superior.
