Abstract: Methods for producing crucibles for holding molten material that contain a reduced amount of gas pockets are disclosed. The methods may involve use of molten silica that may be outgassed prior to or during formation of the crucible. Crucibles produced from such methods and ingots and wafers that are produced from crucibles with a reduced amount of gas pockets are also disclosed.

Abstract: A longneck glass or metal bottle of one-piece integrally formed construction has a body with a closed base and a shoulder at an end of the body remote from the base, and a neck extending from the shoulder along an axis and terminating in a neck finish for attachment of a closure. The bottle neck includes at least one internal embossment for affecting flow of liquid from the body through the neck. In exemplary embodiments of the disclosure, the at least one internal embossment includes at least one internal annular rib or at least one internal rib coplanar with the neck axis or at least one internal spiral rib or at least one internal elliptical rib.

Abstract: A refrigerator having an air-cleaner is provided. The refrigerator includes a main body with a predetermined storage space defined therein, and an air-cleaner including a case fixed to the main body and having at least an inlet and outlet, a decor panel that linearly reciprocates to selectively open and close the outlet, a filter device that filters air sucked through the inlet, a blower that sucks air through the inlet and discharges the air filtered in the filter device through the outlet, and an anion generator that generates anions which are discharged along with the air through the outlet. The air-cleaner is securely mounted to the upper surface of the refrigerator.

Abstract: The invention relates to a method of producing glass articles, especially closure bodies of glass such as, for example, glass stoppers, wherein the following steps are carried out: a) introducing a portion unit of liquid or paste-like glass into a negative mould (10) of an article to be produced; b) applying negative pressure to the negative mould (10) for a period which is sufficient for the liquid or paste-like glass to be sucked into the negative mould (10) and to be brought into exactly fitting contact with the walls of the negative mould (10); c) cooling and de-moulding of the moulded glass article. The invention further relates to an apparatus, to a plant and also to the use of the apparatus and plant in the production of glass articles.

Abstract: A device and process for forming hollow glassware comprising producing solid glass blanks in a manufacturing line, storing the blanks, feeding the blanks to a manufacturing line for forming hollow glassware, preheating the blanks during the feeding step, supplying the preheated blanks to a heating stage, heating to form solid plastically deformable glass globs, transferring the glass gobs to a blow molding stage and blow molding the glass gobs supported by a bottom lifter in a blow mold.

Abstract: The method and apparatus for producing a hollow glass article permit removal of a resulting hollow glass article without severing a moll. By this, glass powder which would otherwise be caused and fallen into the hollow glass article during severing the moil may prevented. The invention also permits elimination of a means for positioning a respective blow head and for stopping rotation thereof. A quantity of molten glass of a disk-shaped configuration is supplied onto a support ring. Each blow head is lowered onto a corresponding support ring. The molten glass on the support ring is held by the blow head by its periphery. Then, the support ring is removed or withdrawn. A quantity of air is blown into the molten glass by means of the blow head so as to form a hollow glass article. Subsequently, the holding ability of the blow head is eliminated, so as to remove or unload the resulting hollow glass article. Alternatively, the support rings may be omitted.

Abstract: A method of producing a glass blank, comprising the steps of: supplying a desired weight of molten glass material to a bearer heated to a temperature of not more than a softening point of the glass material; performing and cancelling, at a temperature of not less than the softening point, pressing of the glass material supplied to the bearer so as to adjust a thickness of the glass material; and cooling the glass material to a temperature of not more than the softening point.

Abstract: Disclosed is a glass press molding method which comprises a step of heating glass material and a mold die composed at least of an upper mold die and a lower mold die for molding the glass material;a step of pressing the glass material by means of the mold die;plural pallets for supporting the glass material and the mold die, each of the pallet supporting the glass material and the mold die in independent manner;a step of transporting, in succession, the pallets each supporting the glass material and the mold die; anda step of transferring the glass material, prior to the pressing step, in such a manner as to place the glass material, heated to a predetermined temperature in the heating step, between the lower mold die and the upper mold die, and to transfer the pallet with the glass material inserted in the mold die to the pressing step.

Abstract: A glassware molding machine includes a plunger and neck mold assembly that cooperates with a carriage and a parison blank mold to form a parison around a first vertical axis (46) in a forming station, and to suspend the completed parison by the neck ring portions. A pair of carriges, and body forming mold portions, alternately cooperate with the neck ring portions to form a container from the parison while the parison remains suspended by the neck ring portions and while the parison remains around the first vertical axis in the forming station. While one pair of forming mold portions transport a completed container from the forming station to a cooling and take-out station with the container held between the closed forming mold portions, the other pair of forming mold portions, are open and, with timing independent of the movement of the first pair move by rectilinear movement back to the forming station.

Abstract: A molten glass parison is expanded to the shape of a mould cavity (16) to thereby form the parison into an article of glassware (A). Air is supplied under pressure to the interior of the parison so that an elevated pressure is created in the parison causing it to expand. The air under pressure passes through an on/off valve (30) before entering the parison and, during the blowing process, the air supply is interrupted at least twice by turning the valve off. Thus, the pressure is caused to fluctuate, during the blowing process.

Abstract: The invention relates to a method and apparatus for pressforming an article of a thermoplastic material. In accordance with the method a charge of molten material is deposited in a mould (14) and the central axis of a pressing plunger (18) and the mould (14) are aligned, after high a pressing operation is performed, the alignment being interrupted just before the end of the pressing operation. The apparatus comprises a frame (2), a mould (14) and a plunger (18), which plunger (18) is connected to a guide mechanism (22) which is movably connected to the frame (2) and which can be coupled rigidly to the mould (14) by coupling means (52).

Abstract: A method wherein the material for manufacturing the fitting is supplied into the mold to the point of intersection of its side channels which are arranged substantially horizontally, and pressing is performed simultaneously in all of the above channels of the mold.
