The co-sintered structure comprises a sintered central layer of yttria stabilized zirconia ("YSZ") which is about 8 mole percent yttria and having a density of at least about 95% of theoretical, and sintered outer layers of strontium lanthanum manganite ("LSM") having the approximate molecular composition La.sub.0.8 Sr.sub.0.2 MnO.sub.3, having a density from about 50 to about 60% of theoretical, and having interconnected porosity from about 40 to 50% with an interconnected pore diameter from about one micron to about five microns. The sintered central layer is sandwiched by and bonded and sintered to the outer layers and is essentially free of significant amounts of manganese.A process for making the unitary composition-of-matter is also disclosed which involves tape casting a LSM tape and then on top thereof casting a YSZ tape. The process comprises presintering LSM powder at 1250.degree. F.

Abstract: A shaped element consists of a soft and preferably elastic foamed material, comprising cellular webs which have been deformed remanently at least over areas. The shaped element is formed from a foamed material granulate, a soft foamed material having a grain size of 2 to 20 mms and filler material, for example cork granulate, rubber granulate, chalk, calcium carbonate, hard polyurethane scraps or thermoplastic plastics material scraps, with a grain size of 2 to 20 mms, which are distributed in the soft foamed material by the foaming action. The cellular webs or walls between the individual floccules of the foamed material granulate and/or of the filler material are remanently deformed over the areas concerned.

Abstract: A microvoided polymeric receiver sheet provides important advantages in the transfer of electrophotographic toner images. Especially advantageous in reducing image defects is the use of such receiver sheets for thermally assisted transfer of toners of small particle size.

Abstract: A skin covered foamed plastic article capable of providing improved softness, feel and comfortableness by reducing the amount of penetration of the liquid foam resin into the skin cover with a thin wadding. The article includes a wadding to be attached on a back side of the surface skin and to make a direct contact with the pad member, having a soft layer contacting the surface skin and a hard layer contacting the pad member which has a constant thickness and is made to be harder than both the soft layer and the pad member.

Abstract: A foldable foam mat has a longitudinal fold line extending over the entire length of the foam mat and a plurality of transverse fold lines which are arranged in pairs and extend, perpendicular to the longitudinal fold line, over half of the mat toward the edges of the mat. One of each of the transverse fold lines, which are arranged in pairs, is configured as a single fold line, and one as a double fold line. Preferably, the fold lines have an asymmetric configuration, referring to the cross section of the foam mat.

Abstract: A process in which a blowing agent dispersion medium is used for producing poly(vinyl chloride) that is particularly well suited for use in insulation covers and the insulation covers made from the resultant poly(vinyl chloride).

Abstract: Novel opalescent coatings are disclosed containing foamed metal oxides. The foamed metal oxides impart a unique opalescence to the coatings, result in more natural hues, softer colors and minimal color travel.

Abstract: A thermoformable composite article comprising a thermoformable foam core which is reinforced with fibers.

Abstract: An improved microporous marking structure has a layer of a microporous material containing a marking fluid and an absorbent backing layer superposed thereon which shortens processing time by absorbing excess marking fluid from the microporous layer. The marking structure according to the invention may be advantageously used to make a self-inking hand stamp. No lengthy step for removing excess ink from the microporous layer is needed.

Abstract: An improved carpet padding comprises a layer of rebonded flexible polyurethane foam, a relatively thin intermediate layer of flexible prime polyurethane foam, and a top layer of polymer film. The layers are laminated together by either a flame or liquid adhesive method. In a preferred embodiment, the bottom layer of rebonded foam is from two to eight times as thick as the intermediate layer of prime foam, and the top layer of polymer film is a metallized polyester embossed with a uniform pattern.

Abstract: Disclosed are vulcanized rubber articles of foamed type and non-foamed type which are prepared by vulcanizing a vulcanizable and foamable (or a vulcanizable) molded product made of a chlorinated ethylene/.alpha.-olefin copolymer rubber, chlorinated polyethylene or chlorosulfonated polyethylene, said vulcanizable and foamable (or vulcanizable) molded product having been surface-treated with a coating solution containing at least one compound selected from alkylammonium halide, alkylphosphonium halide, amine having an acid dissociation constant (pKa) of not less than 10 and amine salt having an acid dissociation constant (pKa) of not less than 10. Also disclosed are processes for the preparation of the vulcanized rubber articles of foamed type and non-foamed type.

Abstract: A continuous process for the production of gypsum board of variable yet predictable density, wherein a fibrous form of stucco produced from gypsum crystals or fibers is combined with standard calcined gypsum and formed into the board. The density of the resultant board varies inversely with the content of fibrous stucco. The process yields lightweight board suitable as standard wallboards and inorganic insulating boards.

Abstract: An erasably markable article formed of a coated substrate that is markable with dry wipe inks without causing permanent discernible distortion of the substrate. The surface after marking is substantially fully erasable. The surface is provided by a smooth coating of cured lacquer preferably a radiation cured lacquer, for example, electron beam radiation cured urethane acrylate. The substrate may be flexible, for example, a biaxially oriented polypropylene multilayer film having a closed cell foam-like core wherein the substrate exhibits electrostatic cling properties. The substrate may also be adhesive coated paper or may be relatively inflexible pressboard.

Abstract: A non-woven ticking fabric is foam-coated to provide good barrier properties to bacteria and liquids and post-cure treated to provide additional bacteriostatic or repellent properties.

Abstract: A protective and decorative sheet material, such as a paint-coated film, which is bonded by an adhesive layer and vacuum thermoforming to an exterior automobile body panel as a substitute for spray painted finishes, can develop surface roughness when exposed to excessive heat for extended periods of time. This defect is unexpectedly reduced or eliminated by employing a foamed, pressure-sensitive adhesive layer.
