Abstract: Method and filter apparatus for extracting entrained lint particles from an effluent air stream prior to discharge into the atmosphere. The filter apparatus and method are used in combination with a vertical settling chamber for separating relatively dense fiber product from airborne lint entrained in a product stream. The filter apparatus includes a housing forming an air stream inlet, a product discharge outlet and a clean air outlet. A rotatable screen is interposed between the air stream inlet and the clean air outlet for collecting the entrained lint on the screen as the effluent air stream flows through the screen for discharge into the atmosphere. Bulk fiber product which settles to the bottom of the chamber is discharged through a rotary valve in the product discharge outlet. The accumulated lint deposit is presented to the product discharge outlet as the screen turns.
Abstract: Hulls are removed from brewer's spent grain (BSG) by drying and milling the BSG in a roller mill having a differential of about 2.5 to about 4.0 and a tight setting, followed by passing the milled mixture through a No. 36 light wire sieve which retains the hulls and permits the bran to pass through. An improved method of making bread with bran which comprises thoroughly mixing the bran with oil and surfactant before adding the other bread ingredients is also described.
Abstract: This invention relates to a manufacturing method and a hermetic glass-to-metal seal suitable for a component in an electric circuit such as a liquid tantalum electrolytic capacitor. The method comprises the steps of fusing a raw material glass in order to form a glass tube; setting a bead, obtained by cutting the glass tube across the axis, in the opening to be sealed, for example, the opening of a member which forms a circuit component; and heating the assembly of the members which composes the circuit component including the bead, above the melting temperature of the bead, with a longitudinal conductor piercing through the bead. This simplified method of manufacturing a hermetic glass-to-metal seal accomplishes a perfect sealing since the sealing glass includes no undesirable impurities such as binder, and since the thermal expansion coefficient of the sealing glass is close to that of the metals used to construct the circuit components, and the sealing glass is stable to electrolyte.

Abstract: First and second arms for holding a blank mold are pivotable about a shaft between an open position and a closed position by means of a motor. A motor operated cam cooperates with rollers on the arms to apply a clamping force to prevent premature movement of the arms toward an open position.
Abstract: The apparatus disclosed for severing gobs issuing its stream from a glass feeder. The shearing mechanism takes the form of two sets, or pairs, of shear blades mounted from diametrically opposed positions relative to the bowl of the feeder. A single cam drives through multiple linkage mechanisms to operate the two pairs of shear mechanisms and synchronisms so that the gobs will be all sheared at the same instant. The links in the linkage mechanism all are provided with the usual adjustments, as to lengths, in order to provide that adjustment after setup which is normally necessary to assure the proper operation of the shears.
Abstract: A glass batch preheater in one stage of which hot flue gases from a glass melting furnace are passed through a bed of cullet and a bed of glass batch material. The bed of cullet, while being heated, filters dust and other particles from the hot flue gases while the bed of glass batch materials is simultaneously heated and fluidized. An alternative preheater includes a first stage and a second supplementary stage to further heat the glass batch material. A separate stage may also be used for elutriation of glass particles. Steam may be injected to provide moisture to the glass batch and for other purposes.

Abstract: Glass fiber sizing compositions and methods of making same and glass fibers containing dried residue of the sizing composition are provided that yield improved efficiencies, reduced migration, reduction in drying conditions, reduced cleaning time and improved housekeeping. The sizing composition, method and glass fiber strand involves the use of a high solids sizing composition having a water solubilized, condensation, cross-linkable, unsaturated polyester resin having free carboxyl groups either pendant or terminal or pendant and terminal and an amino-containing silane and an amount of water to yield a sizing composition having an amount of total solids in the range of about 18 to about 40 weight percent. In addition, other additives can be included in the sizing composition such as additional polyester resins, additional coupling agents, thermoplastic polymers, anti-static agents, film-former modifiers, wetting agents, stabilizers and lubricants.

Abstract: The present invention embraces apparatus for the production of mineral fibers such as glass fibers. In particular, the apparatus comprises a guide member for gathering filaments into side-by-side strands wherein the guide member has a locating hole and support means for holding the guide member normal to the side-by-side strands. The support means comprises a supporting member, a pin member extending upwardly from the support member for positioning the guide member thereon at the locating hole, and an adjustable member extending from the support member and adapted to support the guide member so that the guide member is held above the support member by the pin and the adjustable member.
Abstract: A method for producing decorative glass objects in which the decoration is created by blisters formed by air bubbles within solid glass and/or by a pattern on the outer surface of the glass. When producing glass objects provided with air bubbles by means of known methods the bubbles remain on the surface of the objects which then easily break. In addition, the bubbles are formed at random, which may make them appear as dim impurities. When, in accordance with the invention, molten glass is poured from above in the shape of a band into a hot mould, the molten glass is spread into the mould in layers between which microscopic air bubbles remain. As the glass surface cools, the air enclosed within the bubbles expands in the molten glass which, while cooling, leaves the bubbles as clear pearls inside the glass. As the molten glass is spread in layers towards the wall of the mould, a pattern is formed as the glass surface cools.
