Abstract: TV bulbs are composed of funnels and panels, and the present invention sets forth a novel construction of a funnel for a TV bulb which not only incorporates thinner walls than a conventional funnel, but which also utilizes less total glass when formed into a bulb than a conventional TV bulb, while retaining the required strength and sealing surface area necessary to form an evacuated TV tube when sealed to a viewing panel.

Abstract: A mechanism for automatically and sequentially feeding each of a plurality of pins, for supporting aperture masks adjacent the glass face plates or viewing panels of color television picture tubes, to a mechanism or gun for insertion of each of the pins into the glass of the face plates or viewing panels. The mechanism includes a rotatable turret or cylindrical pin magazine or canister which holds a relatively large quantity or plurality of the pins vertically stacked in columns adjacent the outer periphery of the turret or magazine for the pin feeding operations and which can readily and rapidly be removed from the mechanism and replaced by another full turret or pin magazine when the first one is empty of pins.

Abstract: A mechanism for handling and insertion, in surfaces of face plates or viewing panels for color television picture tubes for support of aperture masks, each of a plurality of relatively elongate support pins having a generally channel-shaped cross-sectional configuration, the mechanism being operable in cooperation with a heating means disposed adjacent said face plate for heating each of said pins prior to and for the purpose of the insertion thereof in said surfaces.

Abstract: An apparatus for heating glass-forming materials within a delivery conduit extending from an electric glass melting furnace to a connector channel is disclosed. The conduit is made from an electrically conductive refractory metal such as molybdenum and is used to conduct current from inside the furnace to its exit end in the channel. Joule effect heating between the exit end of the conduit and an electrode in the connector channel indirectly causes the glass materials within the conduit to partially melt, to the extent that the materials within the conduit may be exhausted from the conduit. A flange assembly for use with a molybdenum conduit is also disclosed.

A thickened annular area of the face plate, adjacent and surrounding the outer perimeter thereof, is preferably provided with a selected maximum thickness at or adjacent the ends of the minor axis of the face plate, a selected minimum thickness at or adjacent the diagonal axis of the face plate and an intermediate thickness at or adjacent the ends of the major axis of the face plate, the regions of the face plate at or adjacent such ends of said axes being the regions of the face plate having the greatest, least and intermediate stresses, respectively, when the face plate is part of an exhausted television picture tube.

Abstract: The present invention relates to decal applying and more specifically to an apparatus for and a method of stripping the backing paper of a water-soaked water-release slide-off decal from the transfer film of the decal and applying such transfer film to a surface of a dish-like article to be decorated.

Abstract: A method of heat treating a plurality of geometrically congruent and flat lens blanks made from a phototropic glass, such heat treating being performed for development of the phototropic properties thereof. A plurality of lens blanks are formed into a stack by alternately positioning and clamping similar areas between the flat surfaces of two flat, annular, spacer members. The stack is then rotated about the longitudinal axis oriented in a substantially horizontal position while evenly heating the lens blanks to the phototropic development temperature of the glass. The stack of blanks is then vertically positioned while continuing the heating thereof and part of each of the blanks sags into the hollow of the spacer member therebelow to form such part of each blank into a curved configuration for an eyeglass lens.

Abstract: A plurality of inner and outer shell molds having virtually identical surface contours are formed from a single master mold such that glass outer layers sagged to the contour of said outer shell molds may be laminated with any glass inner layer sag-formed on said inner shell molds.

Abstract: A mask or face plate, having an orifice or opening formed therethrough of desired size and configuration, is positioned against the discharge face of an extrusion die. The mask restricts the flow of extrudable material through the die so that such material will conform to the size and configuration of the opening or orifice formed through the mask. The face of the mask adjacent the discharge face of the extrusion die is provided with an offset or stepped portion which surrounds the orifice formed through the mask and extends radially outwardly therefrom in a plane extending perpendicular to the axis or direction of extrusion. Preferably the offset planar face is radiused at its juncture with the orifice.

Abstract: An apparatus and method for determining the elevation of the fusion interface between batch and molten glass in an electric glass-melting furnace is disclosed. A probe is driven vertically downwardly through the batch by a combination of a motorized drive assembly and a pneumatic hammer device. When the bottom tip of the probe penetrates the fusion interface, a current path is established from a furnace electrode through the molten glass to the probe tip, with such current flow thereby giving indication that the probe tip has descended to the elevation of the fusion interface.

Abstract: Apparatus for and a method of preforming into an elongate mold charge a gob of molten glass issuing from the outlet orifice of a forehearth and delivering such elongate charge to the forming cavity of a forming mold with the virgin or untouched surface of the charge facing downwardly in such cavity thereby providing to the mold cavity a mold charge having one or a lower surface of high optical quality. A mothering or serving cup receives said gob from said outlet orifice and is horizontally moved to spread or preform the gob into the elongate mold charge with the upper surface thereof being untouched, and the cup is then inverted to deliver the charge to a mold cavity with said upper surface of the gob facing downwardly.

Abstract: A luminaire for providing at least a shallow uniform equatorial zone of illumination above the pavement of airport taxiways and parking areas comprising a housing provided with an upper section having a vertical opening therethrough, a lens within the opening having a shallow frustoconical light exit face extending only slightly above the opening and a steeper generally conical light entrance face coaxial with and disposed below the light-entrance face, a lamp recessed substantially below the entrance face and proximate the axis of the light exit and entrance faces, and a reflector symmetrical about the axis of the exit and entrance faces for reflecting light rays from the lamp into the light entrance face at a predetermined range of angles of incidence therewith.

Abstract: An improved method of centrifugally separating two differing density phases of a multiphase fluid and simultaneously partitioning the phases with a thixotropic material. The thixotropic material is asymmetrically positioned within a closed end of a tubular container such that the exposed or upper surface of the thixotropic material is contoured to form a space for receiving the multiphase fluid between the surface and a sidewall portion of the closed end of the tube.

A pair of corresponding ends of said side portions of the pin are adapted for embedment in said envelope.

Abstract: An improvement in a method of transferring or applying a decal design of a heat release decal or decalcomania to a flat surface such as the flat bottom surface of the concavity of a dish-like article and with only a limited amount or without an appreciable amount of the heat release coating surrounding the decal design being transferred to the flat surface. A mask of a thin resilient material, such as silicone rubber for example, is disposed adjacent the flat surface, such mask embodying a hole or opening having a shape or configuration geometrically similar to the shape of but slightly larger than the face of a pressure head used in applying the design so that, during the transfer operation, the transfer to the flat surface of any appreciable amount of the heat release coating surrounding the decal design is prevented.
