Abstract:
This invention concerns lasable bond-ply materials comprising a nonwoven reinforcing material and at least one resin material. The present invention also includes methods for using the bond-ply of this invention to manufacture high density multilayer printed wiring boards.
Abstract:
This invention provides improved methods and compositions for achieving material coloration using particle scattering. These coloration effects can be designed to be either highly stable or dependent upon the switching effects of either temperature, integrated thermal exposure, moisture absorption, or exposure to actinic radiation. Articles employing materials with these coloration effects are described. Composition comprise a solid, light-transmitting matrix component having a non-liquid particle scattering colorant dispersed. Articles are produced wherein another solid second matrix component has an electronic transition colorant dispersed therein and the first and second compositions are disposed on one another, and optionally interpenetrate each other. Colored articles are produced in the form of fibers, films and molded articles.
Abstract:
A composite molding compound comprising a combination of metal and ceramic powders is disclosed. The powders are combined with a binder, a liquid carrier and other processing additives in a manner to provide uniform distribution of two phases in a material format that facilitates the molding of complex parts at relatively low pressures and temperatures using conventional injection molding machines. The products formed from these molding compounds may be designed with tailored physical and mechanical properties such as thermal conductivity, thermal expansion coefficient, density, elastic modulus and wear properties.
Abstract:
An inkjet printing coating compositions and recording sheets having printable coating compositions on substrates which are suitable for photographic quality prints by inkjet printing technology, such as thermal and piezo. The recording sheet which comprises a substrate and a dried coating composition on the substrate, which coating composition comprises either (i) a hydrophilic or amphiphilic polyether polyurethane plus one or more polymers selected from the group consisting of cellulose ester polymers, cellulose ether polymers and vinyl polymers or (ii) cellulose acetate trimellitate plus optionally one or more polymers selected from the group consisting of cellulose ester polymers, cellulose ether polymers and vinyl polymers; a quaternary ammonium compound; a metal salt chelating agent; and a microcrystalline filler drying agent.
Abstract:
A spin finish which enhances yarn processability and contributes to improved yarn performance. The spin finish is advantageous when compared with conventional spin finishes applied to industrial yarn because the present spin finish enhances yarn processability as evidenced by low forming, improved mechanical quality at lower amounts of spin finish per yarn, improved mechanical quality at higher draw ratios, and minimal depositing. It also improves yarn performance as evidenced by improved strength and wicking.

Abstract:
A process is disclosed for brazing plate/plate and plate/fin multi-channeled structures using an amorphous brazing foil as a brazing filler metal between the parts in order to form uniform joints having optimal dimensions, shape and strength. The parts are assembled in an unconstrained stack, and a controlled load is applied to the top of the stack. The stack is then heated to a temperature at which the interlayer melts and reacts with the base metal to form the joints. The stack is cooled resulting in a brazed structure having the desired characteristics, wherein the brazed joints are optimally formed and the strength of the structure is equal to the underlying strength of the base metal.
