  • Patent number: 10577279
    Abstract: A method of modifying glass frit involves treating the frit with a grain-boundary-healing compound. The method increases transmission and clarity, and reduces haze of a fired enamel coating made from such modified glass frit as compared to a coating not made from such modified glass frit. The grain-boundary-healing compound influences the chemistry at the grain boundaries to prevent haze. The compound burns out to yield a fluxing material that dissolves alkaline carbonates or bicarbonates on the surface of the glass frit. The dissolved species are incorporated into the enamel coating, thereby promoting the fusion of the glass frit and reducing the amount of haze in the enamel coating. The additives also function to prevent the formation of seed crystals on the surface of the glass frit that may inhibit the fusion of the glass frit.

  • Patent number: 5170731
    Abstract: An adjustable needle-craft implement comprises an elongated graspable barrel having a longitudinally extending bore communicating between opposed ends of the barrel. The barrel includes a longitudinally extending plurality of mutually spaced apart transverse slots communicating with said bore's interior and form a barrel indexing rack. An elongated hollow cylinder supports a hollow tubular needle at one end thereof. The cylinder has a resiliently mounted cylinder indexing rack with transversely extending processes thereof that are adapted to be engagable in selective axial register with corresponding ones of the transverse slots in the barrel indexing rack. The cylinder is adapted to be received internally of the bore, in releasably lockable, longitudinally slidable relation therewith.

  • Patent number: 4749856
    Abstract: An optical sensing device which incorporates a suitable optical sensor system, preferably a fiber optics system, with a suitable environmental sensitive polymeric material is presented. The polymeric material must be of the type which undergoes wavelength-independent changes in optical properties in response to environmental changes. Accordingly, preferred polymers include crosslinked, semicrystalline polymers, high strength amorphous polymers, and polymer blends. This novel combination will accurately and, at times, reversibly measure and detect temperature, humidity, pressure, position, radiation, flow, stress/strain, light, color, electric field, and a plurality of other properties with respect to changes in the environment.

  • Patent number: 4642254
    Abstract: A process and device utilizing the memory characteristics of cross-linked polymers for temporarily holding and releasing parts or components is presented. In a first step, a polymeric material or part capable of being cross-linked is formed into a first "memory" shape. Thereafter, in a next step, the polymer is cross-linked via irradiation or any other suitable technique to fix or lock the polymer into the first memory shape. Next, the polymer is heated and deformed to a second shape and thereafter cooled to lock in that second shape. During the deformation process, the cross-linked polymer will preferably be deformed about a second component or part so that upon cooling, the second part will be tightly held by the deformed polymer. Thus, the second part or component will be temporarily held for any desired length of time.

  • Patent number: 3965230
    Abstract: Ductile composite of a cold-rolled rubber reinforced resin sheet and a normally embrittling layer. The rubber reinforced resin in sheet form is cold rolled to reduce its thickness to between 95 and 40 percent of the original thickness. The cold rolled sheet may then be shaped by deep drawing. A protective or decorative layer which would normally impair the impact strength and toughness of unrolled resin is applied to the cold rolled sheet to yield a tough, impact resistant composite.
