  • Patent number: 7138346
    Abstract: A coated glass mat comprises a glass mat substrate having non-woven glass fibers and a coating which essentially uniformly penetrates the glass mat substrate to desired fractional thickness of the coated glass mat. The coating imparts a tensile strength to the coated glass mat which on average is at least 1.33 times greater than the tensile strength of the glass mat substrate without the coating. In example embodiments, penetration of the coating into the glass mat substrate preferably extends to a depth of from twenty five percent of a thickness of the coated glass mat to seventy five percent of the thickness of the coated glass mat. Moreover, a non-coated thickness of the coated glass mat is sufficiently thick for bonding purposes with, e.g., a gypsum slurry or other core materials such as thermoplastic or thermosetting plastics.

  • Patent number: 7132378
    Abstract: Improvements in the high-temperature wash durability and discoloration levels for fabrics having topically applied silver-ion treatments (such as ion-exchange compounds, like zirconium phosphates, glasses and/or zeolites) are provided. Such solid compounds are generally susceptible to discoloration and, due to the solid nature thereof, are typically easy to remove from topical surface applications, particularly when laundered at elevated temperatures. The inventive treatment requires the presence of a specific cross-linked binder, either as a silver-ion overcoat or as a padded-on component of a cross-linked binder admixed with the silver-ion antimicrobial compound. In addition, specific metal halide additives (preferably substantially free from sodium ions) may be utilized to combat the discolorations typical of such silver-ion formulations.

  • Patent number: 6960542
    Abstract: The invention relates to a method for preparation of test bodies for analysis of porous, preferably thermally sprayed, surface layers, which are incorporated by casting in plastic. The method according to the invention is carried out by placing one or more test pieces of the surface layer in a mold introduced into a vacuum chamber, the pressure of which is lowered, pouring a ready-mixed, liquid casting resin into the mold containing the test pieces, again letting the air into the chamber, lifting the test pieces out of the casting resin and allowing the excess resin to drip from the test pieces. After that, they are placed in a mold cavity together with the test pieces with a pulverized resin, and applying pressure and heat to the mold cavity for a predetermined period of time, whereupon the test body is ready to be taken out and lapped.

  • Patent number: 6899965
    Abstract: After an underlying layer, made of a single crystal metal material, has been formed on a semiconductor layer, part or all of the underlying layer is changed into a metal oxide layer by supplying oxygen thereto from above the underlying layer. Then, a ferroelectric or high-dielectric-constant film is further formed on the metal oxide layer. Since the film made of a metal material is formed on the semiconductor layer, a silicon dioxide film or the like is not formed easily. Thus, a dielectric film, which includes an underlying layer with a high dielectric constant and has a large capacitance per unit area, can be obtained. Various defects such as interface states in the semiconductor layer can also be reduced advantageously if these process steps are performed after a thermal oxide film has been formed on the semiconductor layer.
