摘要:
The present invention is directed to a method for forming glass articles containing internal enclosed channels. The method comprises the following steps: (a) delivering and depositing a first or channel-forming ribbon of molten glass to a surface of a mold assembly having a mold cavity possessing at least one channel-forming groove formed therewithin and a peripheral surface, wherein the channel-forming ribbon overlies the mold cavity and the peripheral surface of the mold assembly; (b) allowing the channel-forming ribbon of molten glass to substantially conform to the contour of the mold cavity resulting in the formation of at least one channel in the ribbon of the molten glass; (c) delivering and depositing a second or sealing ribbon of molten glass to the outer surface of the channel-forming ribbon of molten glass wherein the viscosity of the sealing ribbon is such that the sealing ribbon (i) bridges but does not sag into complete contact with the surfaces of at least one channel of the channel-forming ribbon and (ii) forms a hermetic seal wherever the sealing ribbon contacts the channel-forming ribbon to form a glass article possessing at least one enclosed channel; and, (d) removing the glass article from the mold.

The present invention is directed towards a lightweight, sealant-free, thin glass envelope having a front surface and back surface laminated and integrated together, i e. specifically, a unitary envelope body having at least one discharge or ionizable gas channel. The glass envelope exhibits a weight to area ratio of .ltoreq.1.0 g/cm.sup.2. Lightweight, internally channeled light-emitting devices can be formed from these thin glass envelopes by etching electrodes to the envelope, at opposite ends of, and in communication with, the gas channel which contains a discharge or ionizable gas.

摘要:
A method and apparatus for producing a glass ware, such as a bowl or plate, via vacuum forming. A deformable glass ribbon is passed through a pair of parallel rolls or rollers, one of the rollers having a recessed cavity thereon for forming a thicker product zone and a thinner cullet zone on the glass ribbon. The product zone may be specifically configured to compensate for process stretching of the glass ribbon during the vacuum forming process. The product zone is registered over a vacuum mold, and a vacuum is applied to the mold to thereby deform the glass to a concave shape and thus form the dish. The dish is separated from the glass ribbon by trimming at the periphery of the dish.
摘要:
A mold assembly for making blocks of glass and constituting five parts assembled into a mold to make a mold having a cavity open at opposite ends for molding an article of glass as a sheet cut into blocks having an upstanding flange along an edge thereof and a v-shaped ridge along an opposite edge for assembly with other similar articles along a scarf joint defined by the corresponding v-shaped ridges.
摘要:
A method of forming shaped products from thermoplastic materials, by bending a plastic strip with the sued of sahper members which reciprocate both lengthwise and crosswise relative to a continuously moving strip. A device for carrying said method into effect is characterized by the fact that said sahper members are fixed to structural components which are imparted reciprocating motion from a drive both lengthwise and crosswise relative to the strip under treatment.
摘要:
A process for rolling profiled glass bars and an apparatus for this purpose whereby a horizontal roller arrangement with at least one cylindrical roll surface and a pair of lateral roller arrangements, each with a respective roll surface contact the glass ribbon to deform the latter into the desire profile. Means is provided for driving the outer roll arrangements at 0.5 to 1.5 percent higher peripheral speeds than the central roll arrangement.
摘要:
A method and machine for obtaining bent glass sheets. Glass sheets are brought to their softening temperature, then they are caused to travel over a shaping bed of advancing elements for advancing them which are arranged along a path having a circular arc-shaped profile, the sheets progressively assuming their shape on entering the bed and over a first shaping zone, then being hardened by tempering or cooling in a second zone of the bed until they leave, and then the bent glass sheets thus obtained are recovered. The shaping bed is produced with a profile extending in a circular arc of more than 90°, and, on leaving the shaping bed, the hardened glass sheets are moved in a direction opposite that in which they were fed in.
摘要:
The invention relates to a glass-ceramic cooking plate for gas cooking apparatuses, characterized by the fact that it has at least one opening 2 intended to receive a gas burner 3 and several humps 5 of the same height distributed around this opening which are intended to support a cooking utensil which is to be heated by said burner, said humps being an integral part of the plate itself.
