Apparatus and process for the manufacture of a glazing having a complex form for vehicles, comprising a roller heating oven (1), a supporting air bed (7) in the shaping section (2) and a shaping ring (24) for conveying the glass (V) first to an upper shaping mold (17) and then to a tempering station (3), the air bed (7) is formed with fustoconical nozzles of such a size as to enable the ring (24) to pass through them and to be placed beneath the the floating plane of the glass, the ring (24) effecting a first vertical movement to lift the glass (V) toward the shaping mold (17) and a second horizontal movement to convey the glass (V) to the tempering station (3).

An apparatus comprising cathode plates (1, 3) so placed as to form the walls of a rectangular parallelepiped, is able to produce an atom beam for the formation of a thin layer deposited on a substrate and simultaneously an ion beam for the bombardment of the layer during its formation. The process for the deposition is also described. Thin layers can be formed on transparent substrates of large size, to be used as sheets of glass for buildings and motorcars.

The invention relates to a manufactured article formed of two transparent layers, preferably one made of glass and the other made of plastic, adapted to be used as glazing for motor vehicle windows and buildings, consisting of a glass substrate onto which is applied a single-layer plastic comprising a composition of polycaprolactones, a vinyl monomer N-vinyl-2-pyrrolidone,mono-, di-, tri-, tetra-acrylic monomers, a photoinitiator, and flow control agents, reaction catalysts, solvents, plasticizers and adhesion promoters, and aliphatic polyisocyanate, which composition is distributed as a liquid with uniform thickness over the surface, which is spun and exposed to ultraviolet radiations to form the coating.

Apparatus for cutting sheets of plate glass, particularly for making automobile windows, according to a profile programmed in a digital control unit the control output of which is coupled to electrohydraulic amplifiers, each of which controls the movements of an oleodynamic cylinder moving on a fixed piston rod. A cutting head is fixed to one of the cylinders, while a table to bring the sheet of glass to becutinto contact with the cutting head is fixed to the other cylinder. The two cylinders move in perpendicular directions, and their coordinated movements cause the glass to be cut in a programmed profile. A belt conveyor is incorporated in the machine to carry the glass to the table, and may assume a raised position for transport and a lowered position at rest.

This invention relates to a refractor (R) consisting of various flanked dioptric elements (Es) of transparent material with refractive index higher than 1, characterized in that: the elements making up the system have an afocal profile of asymmetrical geometry, such as to allow them to remain in fixed position with time and to concentrate the luminous rays (A) from the solar source on to an underlying smaller than those of the refractor (R) in question. … The dioptric elements (Es) making up the refractor (R) are of the Fresner type but arranged, as said, asymmetrically about a preselected axis of joint (X). The luminous rays (A) are transmitted through the profiled of the various elements at different inclinations. … Of these elements, the central one is formed by two half flat-convex lenses with different focal points, therefore the central element (Ec) is afocal. The lower elements (Ei) with respect to the axis of joint (X), that is, those nearest to the horizontal plane (T), all have greater dioptric powers than the dioptric power of each of the elements lying above the preselected of join; hence the upper elements limit the solar image excursion in the downwards direction, while the lower elements (Ei) straighten the sun's rays in the upwards direction more efficiently. … By keeping the refractor position fixed, the ratio between the refractor profile (L) width and the dimension (L1) within which takes place the maximum excursion of the solar image on the collecting plane is always equal to or greater than 2.
摘要:
A device for electrically connecting the source of electric power and conductors of a defroster for rear window in automobiles, comprising a plate to be welded on the collector of the defroster and a tail for connection to the power source, staggered with respect to the plane of the plate and having a portion of reduced transversal section. The plate is provided with holes and recesses which allow a welded connection with the conductor, so as to withstand stresses due to deformation possibly caused during the operation of assembling the electrical connections (Figure 1).
