摘要： A method and apparatus for delivering a glass stream comprising a first inner layer and a second outer layer, comprising a generally vertical orifice (20), and delivering glass from a second source (24) such that the glass from said second source provides an outer layer about the glass from the first source (22) as it flows through said orifice (20). A resistance heated tube assembly (30) is made of platinum or material having similar resistance heating properties and extends from a glass source to an orifice through which the glass flows from a glass source for the inner layer. The tube assembly (30) includes a tube portion (34) having an inlet end that communicates with the source for the outer layer and an outlet end that communicates with the source. The tube portion (34) has an axis positioned at any angle ranging between the horizontal and vertical but preferably has an axis which is more vertical than horizontal. Flanges (36, 38) are secured to the ends of said tube portion (34), and the flanges are connected to an electric power supply. The cross sectional thickness of said flanges (36, 38) is preferably greater than the thickness of the tube portion (34). Each flange includes an annular groove (42) adjacent its respective end of the tube portion into which the end of said tube portion extends. The flanges (36, 38) are welded to the tube portion (34). Flange heater modules (60, 70) surround each end of the tube portion (34).

摘要： The material is in a fluid state at a predetermined temperature above the ambient temperature. According to the invention:

a) at least two different compositions of this material in the fluid state are prepared;
b) simultaneously and concentrically both the core of the rod with the aid of one of the compositions and a sheath enveloping this core with the aid of another composition are cast; and
c) the casting is then taken to a temperature at which it solidifies to constitute the rod.

Advantageously, the section of the casting is made to grow by its passing through a cylindrical mold shaped to define the final section of the rod.
Application to the manufacture of a glass rod presenting a cross-sectional refractive index gradient.

摘要： Process for the manufacture of glass articles with a transparent glass body (2) bearing a message (3) such as an advertisement, logo or other information. The process consists in transferring the message (3) to a support (4) made from a material heat compatible with the transparent glass body, for example, glass having the same technical and chemical features as the glass of the article (2). The support is then fed into an apparatus for coating with molten glass. The support assembly together with the formable glass enclosing it is then processed to achieve the desired shape with a view to producing the message-bearing article. Within the article, the message seems suspended in a vacuum or is carried on a support of a desired shape, colour and/or texture. The message-bearing article can be a sphere, a carafe stopper, or the bottom of a glass or dish.

摘要： The invention relates to a method of manufacturing successive spherical glass articles, in each of which is accommodated a three-dimensional object or figurine, which method comprises the following steps, to be performed in a suitable sequence, of: (a) providing a container with a mass of molten glass, which container comprises a discharge opening through which liquid glass can be delivered; (b) providing thermally resistant figurines; (c) wholly enclosing successively at least one figurine by molten glass; (d) portioning the molten glass before or after step (c) such that molten glass masses are formed, in each of which a figurine is embedded; and (e) modelling these masses to a spherical form by substantially omnidirectional rolling for a time with simultaneous cooling so that the glass solidifies. According to the invention molten glass is fed to the figurine from at least two sides. The invention also relates to a method for manufacturing an object of glass with at least one three-dimensional figurine enclosed therein, comprising the following steps: introducing an amount of glass having a desired temperature, at which the glass is soft, into a mould cavity; pressing a heated figurine into the glass; pressing the amount of glass with the heated figurine therein substantially to a desired shape.

摘要： An extruding apparatus having at least two independent inlet ports (21, 22), one outlet port (23) communicating with the inlet ports (21, 22), and at least two passages (24, 25) connecting the inlet ports (21, 22) with the outlet port (23), in which a section of a joint portion (26) of the passages (24, 25) has a central portion and an outer peripheral portion which are concentrically arranged, is prepared. A core material (31) is supplied to one of the passages (24) communicating with the central portion of the joint portion (26) from a corresponding inlet port (21), and a cladding material (35) is supplied to the other passage (25) communicating with the outer peripheral portion from a corresponding inlet port (22), thereby causing the two materials (31, 35) to join each other at the joint portion (26). An integral shaped body having a portion corresponding to a core at its central portion and a portion corresponding to a cladding around the central portion is extruded from the outlet port. Water and a binder and other impurities are removed from the shaped body, and the resultant body is consolidated.
