A lightweight and buoyant eyeglass which floats includes a spectacle frame and two spectacle lenses received in the spectacle frame. The spectacle frame and two spectacle lenses are made from a same material, cyclic block copolymer is a main component of the material.

To ease and improve the production of objects, a method is described for producing an object (60) comprising a structural core (10) and an outer coating of polymeric material (52), comprising the steps of (i) coating with polymeric material (50) a lamina (10), wherein the lamina comprises a surface exhibiting macroscopic discontinuities (32) configured so that the polymeric material grips to them in order to form a multilayered piece; (ii) removing parts from the multilayer piece to obtain a contour corresponding to the object, the contour comprising an edge (B) along which a margin of the lamina remains uncovered by the polymeric material.

A method for processing a pair of spectacles having a metal sheet wrapping the surface of an acetate sheet including, cutting a 4.0 acetate sheet; softening the cut acetate sheet through baking, and tapping a steel needle into the acetate sheet; cutting out grooves in the two sides of the acetate sheet, and clamping metal fittings on the acetate sheet; mounting an upper die and a lower die on a 15-ton hydraulic press; clamping a metal material in the grooves formed in the acetate sheet, sleeving the metal material and the acetate sheet in a middle pressing die, and heating the metal material and the acetate sheet sleeved by the middle pressing die in an oven; and, baking the acetate sheet in a sealed oven.

The invention is related to a method of manufacturing of a composite substrate comprising an embedded electronic device by forming in a first substrate a cavity for receiving the electronic device; disposing the electronic device between the first substrate and a second substrate in said cavity; providing a solvent of cellulose acetate in-between the first substrate and the second substrate, maintaining the first substrate and the second substrate in contact together, wherein the electronic device is maintained between the first substrate and the second substrate, forming the composite substrate.

A floatable spectacle frame structure is provided. The floatable spectacle frame structure mainly includes a spectacle frame body, a cover sheet, and a coating member. A space is disposed in the spectacle frame body. The opening end of the space is correspondingly assembled with the cover sheet. The coating member correspondingly coats on the external parts of the spectacle frame body and the cover sheet. Therefore, a gas-filling space is formed in the spectacle frame structure to let the spectacle frame float on water after falling into the water. Hence, the spectacle frame structure can be easily found.

A floatable structure of eyeglasses temple is provided. The floatable structure includes a temple body, a cover sheet, and a coating member. The temple body has a first space, and an opening of the first space is correspondingly assembled and covered by the cover sheet. The cover sheet has a second space to correspond to the first space. The coating member covers the external parts of the temple body and the cover sheet. Therefore, a gas-filling space is formed inside the temple structure. The temple can float on water after glasses fall into the water, so that the glasses can be found easily.

An eyeglasses temple includes a curved section and a support section coupled to the curved section. The curved section includes a metal member, upper and lower plastic members for wrapping the metal member, and a connector installed to an inner side of the support section and proximate to an eyeglasses frame. The metal member is made of a flexible iron material, the upper and lower plastic members are made of silicone and nylon respectively, and the support section is made of nylon. With the metal member made of a flexible iron material, the upper plastic member made of silicon, the lower plastic member made of nylon, and the support section made of nylon, the eyeglasses temple has a higher strength, and provides a friction between the eyeglasses temple and a wearer's ear to prevent the eyeglasses from sliding down or falling out from the wearer's nose bridge and ears.

A manufacturing process of, and the relative laminated, polymeric semi-finished product are disclosed, the laminated, polymeric semi-finished product having in-depth aesthetic features, including at least two mutually welded layers by a lamination process with heat and/or pressure addition, wherein at least one of the layers is a thermoplastic material, in which the following steps are provided: providing a cohesion layer 100-500 micron thick, consisting of thermoplastic polyurethane, featuring in-depth aesthetic patterns; providing polymeric sheets with materials having a softening temperature above the one of the cohesion layer; and laminating at least one of the polymeric sheets at least partly transparent or translucent with the cohesion layer, by heat and/or pressure addition suitable to reach the softening of the cohesion layer featuring aesthetic patterns.

A method for making spectacle arms from composite material with differentiated rigidity, the arms defining a first portion and an adjacent second portion which is less rigid than the first portion. The method includes: providing a first layer of non-cross-linked fiber-reinforced polymer material in the first and second portions; providing a separating element in the first portion, and superimposing a second layer of non-cross-linked fiber-reinforced polymer material on the first layer so as to cover the separating element at the first portion and contact the first layer at the second portion; subjecting the first layer, the second layer, and the separating element interposed between them to a molding process at predetermined pressure and temperature levels so as to cross-link the polymer of the composite material, thus obtaining a thickness and rigidity of the arm at the first portion which are greater than the thickness and rigidity at the second portion.
