  • Patent number: 6660387
    Abstract: A display device substrate which meets requirements for weight reduction, thickness reduction, high reliability, good heat resistance, and good impact resistance all at once. The display device substrate is composed of a pair of glass sheets facing each other and a layer of plastics material interposed between said paired glass sheets in such a way that said glass sheets have an internal compressive strain ascribed to the plastic sheet. Thus, the very thin glass sheets are hardly liable to breakage. This makes light weight and reduced thickness compatible with reliability.

  • Patent number: 4524100
    Abstract: There is prepared in inorganic composite containing a needle-like inorganic material or a fiber-like inorganic material which is present as a mixture in isotropic solid vitreous inorganic material while maintaining its needle-like or fiber-like structure. The inorganic composite is prepared by a process comprising the steps ofkneading a mixture containing a vitreous inorganic material and a needle-like or fiber-like inorganic material which does not melt at the softening point of the vitreous material;molding the mixture into a predetermined shape; andcalcining the molded mixture at a temperature higher than the softening point of the vitreous inorganic material and below the melting point of said needle-like or fiber-like inorganic material.

  • Patent number: 4495223
    Abstract: There is disclosed an improved process for phosphating asbestos fibers by reacting phosphorus chlorides with asbestos fibers in a first reaction vessel heated to a temperature within the range of the boiling temperature of the selected phosphorus chloride at atmospheric pressure and 200.degree. C. above the boiling temperature of said phosphorus chloride, then the phosphated asbestos fibers are cured in a second chamber and purged of any volatile by-product formed during the phosphating step. The products obtained possess reduced haemolytic activity.

  • Patent number: 4486254
    Abstract: This disclosure is directed to a heat-activated patch or repair composition for metal object or surface capable of maintaining its shape at the temperatures to which it is heated to activate and set the composition and ranging from about 250.degree. to about 500.degree. F. comprising a preponderant concentration of a fibrous adhesive containing silicate, soda and asbestos fibrous cement, and lesser concentrations of iron ore and an alumina-containing air set mortar having Pier test of about 600 to about 800 p.s.i. and comprised of alumina, clay and grog (ground-up fired clay). The aforementioned heat-activated patch or repair composition is utilized in a system for repairing such metal object or surface by intimately associating said composition with asbestos cloth, preferably woven asbestos cloth, by applying said composition to one surface of said asbestos cloth and then wrapping the adhesive composition surface of the woven asbestos cloth around the exterior of the metal object or surface to be repaired.

  • Patent number: 4456650
    Abstract: A method for using alkanolamine-carboxylic acid salts as a coating for friction materials which during use contact, at least part of the time, rustable metals. The method comprises contacting the friction material with an aqueous solution comprising at least about 0.05 weight alkanolamine-carboxylic acid salts being the reaction product of:(i) alkanolamine; and(ii) C.sub.4 -C.sub.20 carboxylic acid;and thereafter evaporating water from the aqueous coating on the friction material so as to leave the friction material with a coating comprising alkanolamine-carboxylic acid salts. Friction materials coated by above method are also claimed.
