Abstract: A process for producing glass bottles with shoulders includes a preform preparation step and a finishing step, in which a compressed gas is blown and the preform is rotated by 180° between the preform mold and the finishing mould. Preform preparation is achieved by introducing a glass gob into the mold through an upper aperture; inserting a blowing sleeve into the glass gob, the end of the sleeve extending beyond the shoulders of the outline of the preform of the bottle, the sleeve being closed by a plunger element slidable within its interior; opening the cavity of the sleeve to disengage the plunger element; and blowing air through the sleeve, wherein the final finishing step is achieved in an open preform mold, the volume of the cavity of the finishing mold being greater than the volume of the cavity of the preform mold by 5-20%.

Abstract: An optical fiber array includes a V-groove substrate for housing an uncovered glass fiber section formed at an end portion of an optical fiber contained therein. A lower covered section housing portion houses a covered section of the optical fiber and is formed to be deeper than the V-groove forming portion. An optical fiber is disposed so that the uncovered glass fiber section is housed in the V groove and the covered section is housed in the lower covered section housing portion. A lid substrate is composed of a glass fiber protective portion covering an upper surface of the uncovered glass fiber section and an upper covered section housing portion houses a covered section of the optical fiber. The upper covered section housing portion is formed to be deeper than the glass fiber protective portion and is disposed on the V-groove substrate. A resin is filled in the gaps among the V-groove substrate, the optical fiber, and the lid substrate and cured to give a unitary optical fiber array.

Abstract: A process for the formation of a container of glass, includes a first molding step performed in a preforming mold having pins projecting into the mold over a length less than the thickness of the walls of the preform of the article, the external walls of the preform presenting after removal from the mold recessed portions corresponding to the presence of the projecting pins. A second step is performed in a smooth-walled finishing mold having the shape and the dimensions of the container to be made, the blowing pressure in the interior of the finishing mold being controlled so as to permit a smoothness of the external wall of the container and the formation of air inclusions in the wall of the container.

Abstract: A forming method of a glass product includes the steps of successively setting female press-molds on a gob feeding stage; feeding gob to the female press-molds at the gob feeding stage at predetermined intervals; successively transferring the female press-molds fed with the gob to a press-forming stage; press-forming the gob into a glass product at the press-forming stage; and removing the press-formed glass product at a product removing stage.

Abstract: An individual section of a multiple section glassware forming machine has three operating stations in spaced apart relation along the longitudinal center line of the section. Three independently operable transfer means move, respectively, a parison formed in an upright position at the first station to the second station, a further formed parison from the second station to the third station, and an article of glassware from the third station to a takeout position over a deadplate. The operating speed and rate of acceleration of each of the three transfer means is selected independently of the operating speed and rate of acceleration of both the other transfer means to effect its movement in the shortest practicable time compatible with the state of the glass during the movement of that transfer means.

Abstract: An individual section of a multiple section glassware forming machine has three operating stations in spaced apart relation along the longitudinal center line of the section. A parison formed in the first station is transferred to the second station and released there by a first transfer means. A second transfer means which is operated independently of the first transfer means engages the parison at the second station and moves the parison to a third station in which an article of glassware is formed. By adjusting the time of operation of either transfer means relative to the other, the period of time during which the parison reheats may be changed without altering the relative timing of any of the machine functions which together make up the parison-forming cycle or the relative timing of any of the machine functions which together comprise the glassware forming cycle.

Abstract: A glassware forming machine has three operating stations, in the first of which a parison is formed in an inverted position. First transfer means transfers a parison from the first station to a second station where the parison is released by the first transfer means in an upright position. A second transfer means receives the released parison at the second station and supports it for a selected time, after which the second transfer means transfers the parison to a third station, releases it and reverts to a position at the second station for receiving a further parison. A third transfer means operative independently of both the first and second transfer means removes an article of glassware from the third station and supports the glassware for a cooling period beyond the third station.

Abstract: Glassware forming apparatus includes a parison mold, a blow mold, a pair of neck rings for supporting glassware blanks, first and second invert arms for supporting the neck rings and first and second arbors for supporting the first and second invert arms, respectively. The invert arms support their respective neck rings for movement in a common vertical plane. The axes of the arbors extend generally parallel to one another and generally perpendicular to the common plane. The molds have parallel vertical axes lying in said common vertical plane. Apparatus is provided for shifting the arbors such that their axes move toward and away from one another during an operating cycle. Apparatus is provided for pivoting the arbors about their axes to move the neck rings in invert and revert arcs between the parison mold and the blow mold.

Abstract: A blown hollow glass object having an optical inner wall structure is produced by pressing a plunger against a heated glass blank which has been inserted into a hollow mold cavity. The plunger is configured to taper toward a narrower end in the direction in which the plunger is introduced into the mold cavity. After formation of the optical inner wall structure by pressing of the plunger against the glass blank, the plunger is longitudinally withdrawn. The optical inner wall of the glass object is formed as a result of a generally helically shaped molding pattern defined about the exterior surface of the plunger. The molding pattern is configured in such a way as to prevent deformation of the optical inner wall structure when the plunger is withdrawn.

Abstract: An improved method is disclosed for forming glass bottles by the blow and blow process. A parison mold having a one-piece annular blank mold section and split neck and shoulder mold sections is charged fully with molten glass. Air is subsequently blown through a manifold covering the upper end of the parison mold to force the molten glass into an annular space defined by a cavity in the neck mold section and a neck pin projected into the neck mold cavity. The neck pin is then reciprocated from the neck mold cavity, and air is blown through the molded neck to cause the molten glass to chill its surface by pressure contact with the inside of an upright truncated pyramidal-shaped cavity formed in the blank mold section. The glass which comes into contact with the cavity walls in the blank mold section develops a very uniform enamel due to the uniform cooling achieved with the solid annular blank mold section.

Abstract: The individual section of a Hartford I. S. type machine is modified to permit forming the parisons in an upright orientation, and also for transferring the upright parisons from the blank to the blow side of the section without disturbing this upright orientation. The pressing plungers at the blank station are mounted for movement toward and away from the upwardly open blank mold cavities, and each blank mold cavity is defined in part by partible neck ring molds, in part by a lower solid blank or body mold, and finally by intermediate partible mold sections which engage the upper neck ring molds and also the lower body mold. These intermediate mold sections at the blank side of the machine are mounted on the existing blank mold holder arms.
