Abstract: Two fixed heads are used to lubricate a split-mold. The heads do not interfere with the movements of the mold and are effective to inject a jet of a gas that forms a powdery carbonaceous material. When the mold is open, the injection axis of each head is just about in line with the axis of the associated half-casting.

Abstract: Apparatus for spraying lubricant into closed moulds of a glass forming machine has the spray outlets on a carrier structure which is pivoted on the funnel arm shaft of the machine. For lubrication a pneumatic cylinder couples it to its support, fast with the funnel arm shaft so that the carrier and spray outlets are moved over the moulds. During a moulding cycle the carrier is held back inoperative by a spring so the funnels can be used normally. A method of moulding glass parisons includes selectively moving the carrier structure and spray outlets to spray lubricant at selected intervals to effect periodic lubrication cycles.

Abstract: A multipiece spray assembly is disclosed which provides an annular axially and radially inwardly inclined nozzle passage operative to rapidly and efficiently apply a substantially complete and uniform coating to the inner surfaces of a forming cavity. Additional nozzle means may also be provided to simultaneously coat an overlying forming tool.

Abstract: A new spray ring apparatus for use in forming apparatus of the type used in metal forming and glassware forming which include a forming cavity into which a fluid lubricant material is sprayed. In one embodiment, the spray ring includes a plurality of nozzles through which the fluid lubricant material is sprayed into the cavity in a tangential helical flow pattern to thereby uniformly coat the interior surfaces of the cavity prior to the forming of the metal or glassware parts therein. In another embodiment, an annular nozzle flowpath is provided with the helical flow pattern being imparted to the lubricant material via a tangentially disposed inlet opening into an annular manifold chamber. A plurality of nozzle openings may be provided in the outer surface of the spray ring which may operate to uniformly coat the outer surfaces of a punch or similar type of associated overlying forming tool.

Abstract: Apparatus for spraying lubricant onto the blank moulds of an IS glass forming machine has static spray heads above the open positions of the mould halves, to spray downwardly onto them when the mould halves are open. Electrical and pneumatic equipment in a separate cabinet causes metered quantities of lubricant to be delivered after a predetermined number of machine cycles. The neck rings may also be sprayed by a further static spray head which is positioned above the mould halves and sprays through the space between them when they are open.

Abstract: An apparatus for spraying an oil-water-air mixture onto a plurality of shear blades adjacent to a glass gob feeder and including a multi-compartmented mixing block, a flow meter in the water line, an oil-water ratio controller, signal means connecting the flow meter output to the ratio controller for actuating an oil injector in response to the water flow whereby a metered quantity of oil-water mixture is entrained with the air in the mixing block and individual spray nozzles are connected to each compartment.

Abstract: The present invention is directed to an apparatus and process for the ion change hardening of glassware by passing the glassware through a stream of molten salt. The glassware may be arranged at different levels on a conveying means, provided with perforations to allow the molten salt to fall from level to level from an overhead salt distributor. The glassware may be positioned on a horizontally spinning rack so that molten salt continuously fills up and empties from the glassware. The molten salt is recycled from the bottom of the apparatus and may be replenished by adding salt to the recycle stream.

Abstract: In a glass ware forming apparatus including a blank mold, a split blow mold, a bottom plate, and a neck ring assembly, the inclusion of a nozzle assembly mounted on the blank mold supporting structure and oriented to spray lubricant onto the inner walls of the open blow mold and further nozzle means mounted to spray lubricant onto the inner surface of the bottom plate prior to the closing of the blow mold about a parison for blow forming the parison into a finished form.

Abstract: A device for an intermittent application of a lubrication or a separation liquid to a component part of a glass-forming machine engageable with molten glass, includes an intermittently driven high-pressure pump and a spraying nozzle connected to the pump by a pressure conduit to apply momentarily a cone of atomized lubrication or separation liquid on the machine part at a pressure of at least 100 bars.

Abstract: A new spray ring apparatus for use in metal forming and glassware forming machines of the type having a forming cavity into which a fluid lubricant material is sprayed, said spray ring including a plurality of nozzles through which the fluid lubricant material is sprayed into the cavity in a tangential helical flow pattern to thereby uniformly coat the interior surfaces of the cavity prior to the forming of the metal or glassware parts therein.

Abstract: A process and apparatus for producing glass foil is disclosed in which a thin glass foil is produced by conveying a glass melt from a rotatable crucible of a smelting furnace through an annular distribution reservoir and a distributing disk having flow-through slots. Jets of glass emerge from the flow-through slots and are combined at a funnel-shaped wall into a hollow, cylindrical glass mass. Due to its weight and to heating by pressurized, gas-heated heating and cooling zones, the cylindrical glass mass flows downward, and is stretched until it reaches a pre-determined wall thickness by auxiliary conveyor belts. The hollow cylinder of glass is then split on one side by a separating device, flattened, conveyed to a bath of liquids, and then drawn-off at full width in the form of a glass foil by a draw-off guide roller. After the glass foil is drawn-off, the auxiliary conveyor belts are moved laterally so that they are no longer in physical contact with the glass cylinder.

Abstract: Release and lubricating composition for avoiding seizure between molten glass and metal molds for forming glass articles, for minimizing wear between mold sections and for improving the pack of glassware, comprising, a dispersion of graphite in a polyphenylene sulfide, molds having such composition coated thereon, and a method of applying the composition to molten glass contacting surfaces comprising dispersing the composition containing graphite with the polyphenylene sulfide in the form of small particles in a carrier, applying the dispersed composition to the glass contacting surface and then curing the coating at an elevated temperature, including curing resulting from hot molds during glassware production.

Abstract: An improvement is provided in methods for conveying a charge, or gob, of formable glass along glass loading equipment, from the point of severance of the gob to the point where the charge of formable glass is discharged into a mold for forming; the improvement essentially resides in increasing the effective glass contacting life of lubricants, which have been previously employed on the glass loading equipment, by providing a support coating for the previously employed lubricants, which support coating comprises a transition metal in a major amount applied from a flame spray or plasma spray and presents an abrasion-resistant, rough surface profile upon which the previously employed lubricants are then deposited.

These laminates may be used at various glass contacting locations for handling glass in its process of manufacture.
