Abstract: The present invention relates to a method and apparatus for the production of fibrous insulation, especially relatively thick fibrous insulation. Previously some relatively thick insulation has been produced through lamination techniques using a plurality of insulation layers, which possibly included the use of a continuous fibrous hinge as an alignment aid during lamination. However, proper alignment using a continuous hinge is difficult and leaves an objectionable bulge of fibrous material. The present invention eliminates the fibrous bulge of the prior art and provides a more accurate means by which to substantially accurately align the layers of fibrous insulation.

Abstract: A method and apparatus for the reclamation of inorganic fibers from waste continuous strips of inorganic fibers. A binding agent, such as an organic binder, must be removed before the fibers can be reused or further processed. One or more layers of continuous strips are conveyed to a heating zone where the strips 42 are supported along a predetermined path as a heating fluid is drawn rapidly through the strips. The heating fluid is controlled as to temperature, pressure and mass flow rate to insure that the binder is properly decomposed and that the products of decomposition are rapidly carried away from the strips to prevent heat buildup which could cause a temperature increase to the fusion point of the fibers. Process temperatures are thus suitably controlled to below the fusion temperature of the fiber material.

Abstract: This invention relates to glass filament production. Conventionally the hollow cooling tubes and/or metal bars utilized in the making of continuous glass fibers have been constructed of high temperature corrosion resistant materials whose costs are exorbitant for extensive present day factory operations. The present invention dramatically reduces the price of cooling tubes 24 suitable for use in the making of glass filaments by coating or cladding a relatively inexpensive base or substrate metal 48 such as copper or refractory metal such as nickel, Inconel or molybdenum, and alloys thereof with a high temperature corrosion resistant material 50 such as the noble metals, e.g., platinum, palladium, rhodium, iridium, gold, silver or alloys thereof. Fins 52 which may be attached to the cooling tubes 24 may be made either of a solid noble metal or may also be coated or clad in the same manner as the cooling tubes 24.

Abstract: An improved multiple article beverage package for cans or the like. The package is designed to contain a plurality of cans with the carrier being carried by a handle formed in the top panel of the carrier. An improved tear-out dispensing feature is provided in the subject package which is formed on one side of the package and is designed to be torn out of a portion of the side panels and a portion of the end closure flaps and to be folded downwardly to expose an immediately adjacent can within the package whenever the package is filled. The package also contains retaining means formed on the package for retaining the cans in the package after the tear-out dispenser feature has been opened so that only one can at a time may be removed without the remaining cans rolling out of the package by being forced out by the weight of cans positioned above the lower level of cans.

Abstract: The present invention concerns stacking of shingles, in particular shingles having one edge portion thicker than the other edge portion. Such shingles require that at least some of the shingles in a stack be oriented to place the thicker edge thereof opposite the thicker edge of the other shingles in the stack to form a neat and easily packaged stack of shingles. Such a stack of shingles must be formed quickly and accurately in order to keep up with the high rate of shingle production. The present invention accomplishes this by permitting selected shingles to be dropped and simultaneously rotated about a longitudinal axis as the shingles drop from one star wheel catcher (20) to another star wheel catcher (30). This rotation takes place by applying a substantial moment to the shingle as it falls by interposing specially shaped flipping fingers (46) in the path of the shingle.

Abstract: Refractory ceramic fiber blanket modules with a continuous strip of ceramic fiber material folded into a number of layers in a serpentine fashion are used to insulate high temperature equipment. The blanket is supported by support structure which penetrates the blanket in the vicinity of folds near the furnace wall, providing increased strength against tearing away of the blanket from the supports.
