Abstract: This invention relates to novel whitening agents for cellulosic substrates. The whitening agents are comprised of at least two components: at least one chromophore component and at least one polymeric component. Suitable chromophore components generally fluoresce blue, red, violet, or purple color when exposed to ultraviolet light, or they may absorb light to reflect these same shades. The whitening agents are further characterized by having a dispersion component value of the Hansen Solubility Parameter of less than or equal to about 17 MPa0.5. This invention also relates to laundry care compositions including but not limited to liquid and/or powder laundry detergent formulations and rinse added fabric softening (RAFS) compositions that comprise such whitening agents.

Abstract: A method for forming a high aspect ratio sintered powder anode with low warpage, an anode made thereby and a cathode comprising the anode are provided. The method comprises placing a multiplicity of anode precursors on a forming substrate in a common plane wherein no more than 10% of the anode precursors are out of the common plane. A second substrate is then placed over the forming substrate with the anode precursors between the forming substrate and the second substrate thereby forming a sandwiched assembly. The sandwiched assembly is heated to a sintering temperature of the anode precursors thereby forming the sintered powder anodes. The and sintered powder anodes are removed from between the forming substrate and the second substrate.

Abstract: An improved capacitor is described. The capacitor has an anode with an anode lead wire extending from a first face of the anode. A dielectric layer is on the anode and a cathode is on the dielectric. An anode lead with an anode base and a cavernous anode protrusion extending from the base is provided wherein the anode lead wire is in electrical contact with the anode protrusion. A cathode lead with a cathode base is provided wherein the cathode base is in electrical contact with the cathode on a side face wherein the side face is adjacent the first face and the cathode base and said anode base are coplanar.

Abstract: An apparatus is disclosed for drying materials wet with one or more solvents, particularly hygroscopic materials and materials wet with a high boiling point (low vapor pressure) solvent that are sensitive to heat. Wet material is loaded into a chamber, which is then sealed and caused to oscillate back and forth. Vacuum is enlisted to provide rapid evaporation of solvent at a lower temperature than possible at standard atmospheric pressure. The material is oscillated until a sudden decrease in the residual pressure of the chamber, which indicates completion of the drying cycle. Because vacuum is applied to an oscillating chamber, a rotary vacuum seal is not required to accomplish drying in accordance with the practice of the instant invention.

Abstract: A method of thermally removing binder from porous compacts pressed from metallic or ceramic materials using atmospheric pressure and binder-free compacts produced therefrom.

Abstract: Metal powders are pressed into compacts more readily through the addition of a minor percentage of dimethyl sulfone binder. Dimethyl sulfone may be dry-blended with the metal powder by mixing it in the form of a powder, or it may be wet-blended by first dissolving it in a suitable solvent, then adding it to the metal powder and evaporating the solvent. Dimethyl sulfone may be almost completely removed from compacts pressed from tantalum, etc., either by vacuum distillation or by water leaching, to leave compacts uncontaminated by the binder and suitable for further processing into capacitor anodes, etc.

Abstract: Organic acid-based binders are efficiently removed from powder metallurgy compacts, such as tantalum capacitor anode bodies, by immersion in a heated aqueous alkanolamine solution followed by rinsing in warm water. This method results in lower residual carbon and oxygen levels than are found with thermal binder removal methods.
