Abstract: A device for forming one or more wellbore sealants in a wellbore can include a wellbore barrier and a cured polymer. The wellbore barrier can be positioned in the wellbore. The cured polymer can be positioned with respect to the wellbore barrier for swelling the device from a compressed configuration to a swelled configuration for forming one or more wellbore sealants in the wellbore.

Abstract: Fiberballs have been prepared from mechanically-crimped fibers having both a primary crimp and a secondary crimp with specific configurations, especially amplitudes and frequencies. The fiberballs may contain a proportion of other fibers, particularly binder fibers, and used for making molded structures.

Abstract: Pillows and other filled articles are filled with bicomponent polyester fibers that have "spiral crimp" on account of a difference in chain-branched content of the polyester polymers of the components. Such bicomponent fibers are preferably novel hollow "spiral crimp" bicomponent fibers.

Abstract: An apparatus and method for transporting firewood are provided. The apparatus includes a container having an upright portion and a lower portion extending outwardly from the upright portion. Edges of the upright portion define an upper opening, and edges of the lower portion define a lower opening. Firewood is placed in the upper opening and removed from the lower opening. Doors are provided to cover the upper and lower openings. Wheels are provided to transport the container from one location to another, and belt and sprocket assemblies are provided for enabling smooth transport of the container over obstacles.

Abstract: An apparatus for indicating a quantity of electrical information in decimal notation. An input signal having a voltage level proportional to the quantity to be indicated is compared with a plurality of decimally related reference voltage levels to generate a separate decade enable signal for each reference voltage level which is equal to or less than the input signal voltage level. The input signal and the decade enable signals are utilized to generate a units signal having a voltage level proportional to the difference between the input signal voltage level and the voltage level of the largest reference voltage for which a decade enable signal has been generated. The units signal voltage level is compared with the reference voltage levels to generate a separate units enable signal for each of the reference voltage levels which are equal to or less than the units signal voltage level.
