A soundproofing material including a porous body having a cell structure and including inorganic fibers other than asbestos, wherein an average cell diameter is more than 300 μm and 1000 μm or less, a bulk density is 0.007 to 0.024 g/cm.sup.3, and a flow resistivity is 170,000 to 2,000,000 Ns/m.sup.4.

A property-enhanced cover sheet, and methods for forming a property-enhanced cover sheet, for a portable electronic device are disclosed. A property-enhanced cover sheet is formed by thermoforming a glass sheet into a specified contour shape while modifying one or more properties of the glass. Other property-enhanced sheets can be formed by layering two or more glass sheets having different material properties, and then thermoforming the layered sheets into a required contour shape. Property enhancement for a cover sheet includes, hardness, scratch resistance, strength, elasticity, texture and the like.

The present invention relates to a printing substance for coating glass surfaces by way of an ink jet printing method, the printing substance comprising A) at least one monomer having at least one C—C double bond; B) at least one cationically curable monomer comprising epoxy groups; C) at least one cationically curable monomer comprising oxetane groups; D) at least one adhesion agent. In addition, the present invention describes a method for producing the printing substance and the use thereof.

A rear cover of an electronic device is provided. The rear cover includes a glass substrate including a first face facing a first direction, a second face facing a second direction opposite to the first direction, and at least one side face disposed between the first face and the second face, a roughness layer formed on the first face and having a first roughness, a hairline pattern formed on the roughness layer and having a second roughness, and a hard coating layer formed on the roughness layer and the hairline pattern.

A device for repairing a damaged spot in a repair area of a glass pane includes an attachment portion, a repair portion and a first sensor device. The attachment portion is configured to be releasably attached to a main surface of the glass pane. The repair portion is configured to repair the glass pane. The first sensor device is configured to be brought into data connection with a control device and to determine a contact pressure with which an injector unit, which is configured to be disposed on the repair portion, is pressed onto the repair area in order to release a repair agent.

Disclosed is a method for manufacturing ultra-thin glass. The method includes: patterning, on a mother glass substrate comprising a plurality of display cells and a dummy area surrounding the display cells, a cutting line having a shape corresponding to the display cells; forming a mother glass protective film on the mother glass substrate; forming a through-hole which corresponds to the cutting line by etching the mother glass substrate; and cutting bridges which are formed by the mother glass substrate and connect the through-holes.

The system includes a robot multi-jet system having a spray section, a drier section, and a catalyst section. The drier section includes a warm air blower, the catalyst section includes a photocatalyst tank, and the spray section includes a plurality of jet extensions. A first jet extension connected to the photocatalyst tank sprays a uniform layer of a photocatalyst through a first set of jets, and a second jet extension that is mechanically connected to the drier section and in fluid communication with the warm air blower is configured to spray a gas onto an inner surface of the glass tube with a second set of jets. Both the drier section and the catalyst section are mounted on wheels to move the system on the inner surface of the glass tube. A motor is electrically connected to a battery mounted within the robot and mounted to the wheels.

A system for use in glass production technology such as for production of glass packaging, glassware, glass home equipments, wherein the system allows all kinds of design additions such as color, pattern, texture, decor, seal and form changing processes to be applied to the product without requiring re-firing of the product, after removal of the product from the moulds in the production lines while the product is still hot and the temperature is kept constant.

A closable portable painting palette case has a glass paint mixing surface with a glazed or color backing. The glazed or color backing uses an automotive process that may include an adhesion promoter, a color application, an opaque base coat application, and a clear coat application. The glass paint mixing surface may be a shatter-resistant glass with a wrong or rough side and a right or smooth side, so that the glazed or color backing is applied to the wrong or rough side, leaving the right or smooth side for use in mixing paint smears. The glazing or color backing may be white, silver, or gray, depending on the application. A magnetic attachment may be provided for attaching the palette to a sketchbook or watercolor book for hands-free use. Molded or magnetic paint pans may be provided in the closable portable painting palette.

Systems and methods are disclosed for depositing particles on a substrate, the method comprising generating a thermal bubble on a surface of a substrate submerged in a medium having suspended particles such that the thermal bubble deposits the particles on the substrate; and deflating the thermal bubble such that the deposited particles are pulled toward a central position to form an island of particles.
