Abstract: A radiation resistant optical waveguide fiber doped with fluorine or drawn with low tension in the fiber. The fluorine doping is substantially constant across the core and a portion of the clad adjacent the core. The concentration of the fluorine is in the range of about 0.3 to 3.0 weight percent. The draw tension is less than or equal to about 5 grams (40 dynes/cm.sup.2) to achieve optimum radiation resistance. A synergy is found when fluorine and low draw tension are applied to a fiber. Improvement in radiation resistance is largely independent of fiber type and geometry. Further improvement in radiation resistance is found when germanium is doped in a portion of the clad adjacent the core.

Abstract: Encapsulated aluminum salts are produced by combining and heating an aqueous aluminum salt selected from aluminum halohydrate, aluminum nitrohydrate and mixtures thereof; a hydrophobic liquid; and a carboxylate. The mixture is heated until substantially all of the free water has been removed. The encapsulated aluminum salts precipitate out after the removal of the water. The encapsulated aluminum salts are useful in deodorant and antiperspirant compositions.

Abstract: A process of making a polydiorganosiloxane-silica foundation mixture from a free-flowing, powdered, surface-modified, reinforcing silica-polydiorganosiloxane concentrate used to make, for example, RTV silicone sealant compositions which have non-sag properties. The foundation mixtures are made by combining, mixing, and heating a reinforcing silica filler and a diol surface modifying agent to a temperature of 20.degree. C. to <180.degree. C. using 0.05 to 0.5 parts by weight of the diol per one part by weight of the silica. Polydiorganosiloxane is added gradually to the resulting fluidized filler over a time period of less than 10 minutes to obtain the free flowing powdered reinforcing silica-polydiorganosiloxane concentrate. The foundation mixture is obtained by massing the concentrate and adding more polydiorganosiloxane to obtain a mixture which has from 5 to 20 weight percent silica filler. The foundation mixtures have a plateau stress of >700 dynes/cm.sup.
Abstract: Oligomers wherein phenylalkylsiloxane units comprise at least a portion of the repeating units increase the ability to penetrate porous substrates that is exhibited by crosslinkable liquid organosiloxane compositions containing polyorganosiloxanes when the oligomer exhibits limited compatibility with the crosslinkable polyorganosiloxane(s) present in the curable organosiloxane composition.

The foundation mixtures are made by combining, mixing, and heating a reinforcing silica filler and a surface modifying agent to a temperature of >90.degree. C. to <180.degree. C. using 0.1 to 0.5 parts by weight of the surface modifying agent per one part by weight of the silica. Polydiorganosiloxane is added gradually to the resulting fluidized filler over a time period of less than 10 minutes to obtain the free flowing powdered reinforcing silica-polydiorganosiloxane concentrate. The foundation mixture is obtained by massing the concentrate and adding more polydiorganosiloxane to obtain a mixture which has from 8 to 20 weight percent silica filler.
Abstract: A method and apparatus for making color filters for liquid crystal display panels. A transfer layer is formed on a collector roll, and a raised pattern corresponding to the desired black matrix pattern is formed on the transfer layer by embossing. A plurality of colored ink patterns is formed in the appropriate location within the boundaries formed by the raised pattern, thereby forming the multicolor image that will become the color filter. This multicolored image is then transferred to the substrate. Preferably, the inks are deposited into the black matrix pattern using typographic imaging pins which are smaller than the cells of the black matrix pattern.
Abstract: A method of producing a fibrous product is disclosed. Molten material is introduced into a rotating spinner which includes a peripheral wall having a plurality of orifices. The molten material is centrifuged through the orifices to create fibers. The fibers are directed generally downwardly and away from the spinner. The fibers are intercepted on a folded conveyor so that the fibers are draped over the folded conveyor. The fibers form first and second suspended portions which are oriented generally vertically. The folded conveyor and intercepted fibers are moved away from the spinner. The first and second portions of the suspended fibers are raised to a generally horizontal orientation by unfolding the conveyor, thereby producing a generally planar fibrous product.

Abstract: A termite shield according to the present invention provides a physical barrier between a foundation and a wooden building structure, a detection mechanism for detecting termite presence, and a chemical termiticide in the form of a bait block. The termite shield includes a sill plate barrier which is positioned between a masonry foundation and a sill of a wooden structure. An interior bait block holder is removably attached to the sill plate barrier on an interior side of the foundation, and an exterior bait block holder is removably attached to the sill plate barrier at an exterior side of the foundation. The bait block holders may be provided with a block of wood which is inspected periodically to detect the activity of termites. If termites are detected, the block of wood may be replaced with a bait block of cellulosic material containing termiticide.

Abstract: A method and apparatus for pressing glass articles. A single mold may be utilized for each article being pressed. The plunger has a ring-like member movably attached thereto. After pressing, when the plunger is retracted from the plunger, the plunger retains the glass article thereon. The ring-like member is then lowered relative to the plunger, thereby removing the pressed article therefrom.

Abstract: A tradeoff between crosstalk and channel bandwidth in dense wavelength demultiplexers is achieved by varying mode fields of input and output waveguides. Funnels are formed between inner and outer ends of the input and output waveguides to increase mode field radii, which results in decreased crosstalk attenuation but larger bandwidth channels.
