Abstract: An item recognition system and method which is particularly suited for automating entry of items too small to carry readable bar code labels. The system includes a camera which digitizes the image to produce a digitized image and a gray-scale digitized image. A binary image of the gray-scale image is then produced from which the computer records an image of the item, and a computer coupled to the camera which digitizes the image to produce a digitized image and a gray-scale digitized image. A binary image of the gray-scale image is then produced from which the computer identifies the item from the binary image and obtains the price from a price-lookup file.

Abstract: The present invention includes one or more fibers (12) made of a ceramic, such as glass, which are each suitable for being used as a reinforcing fiber (12) in a composite product or article. Each ceramic reinforcing fiber (12) has a ceramic core (24) and one or more ceramic layers (22) disposed around the core (24). The layered structure of the present ceramic reinforcing fiber (12) improves the overall strength and fracture toughness of the fiber (12). Before a crack propagating through the outermost layer (22) can propagate through the remainder of the fiber (12), a new crack must be initiated at the pristine surface (i.e., interface) of the underlying ceramic material. When there are multiple layers (22), a new crack must be initiated and propagate through each successive layer (22) of ceramic. A ceramic fiber composite article is made by disposing a plurality of the ceramic reinforcing fibers (12) into a suitable matrix.

Abstract: In a method of making a shaped fiber, a stream of fiberizable material is provided with an original shape and a void fraction from 20% to 80%. The void fraction can be provided by forming a hollow stream, a porous stream or a significantly shaped stream. The stream of fiberizable material has a soft portion at which the shape of the stream can be changed. Preferably the stream is provided by discharging molten fiberizable material through a first tube located in an orifice in a wall of a container, and introducing gas through a second tube into the interior of the molten material. The fiber stream is contacted to change the shape of the stream at the soft portion, preferably by applying torsion downstream from the soft portion. Torsion can be applied by contacting the fiber stream with a first surface moving in a direction generally transverse to the longitudinal axis of the stream.

Abstract: This invention is a strand of silicate glass fibers with a carbon skin or sheath around each glass fiber of the strand. The invention uses hydrocarbon pyrolysis with silicate fiber glass manufacturing to produce fibers using conventional melt-bushing technology. The formation of a carbon skin or sheath on the silicate glass fibers offers numerous advantages. For example, pyrolyzing hydrocarbons is endothermic. Heat is removed in the process and fibers are cooled faster. This helps to achieve higher throughput.

Abstract: A method for controlling secondary foam in a glass melting process is provided in which an oxidizing agent is added to a second melt region (32) of a glass furnace (14) where secondary foam (52) is formed. The oxidizing agent may be supplied directly to the second melt region (32) or may be added to the molten glass composition (46) with the batch raw materials (44) in a first melt region (30). When added directly, the oxidizing agent is preferably an oxidizing gas. When added with the batch materials (44), the oxidizing agent is a high temperature oxidizing agent which is inactive in the first melt region (30) yet active in the second melt region (32).
