  • Publication number: 20120108148
    Abstract: The method of modifying the flat glass surface is based on that the surface of a glass is worked by abrasive grains of synthetic diamond which are situated in the mass of plastic threads that are a part of a rotating brush. The glass is first tarnished using brushes with rougher abrasive grains of synthetic diamond and then tarnishing is finished using brushes with smaller abrasive grains. With the brushes, it is also possible to modify already sandblasted glass surface. The apparatus for modifying glass surface is made up of at least one rotating brush (9, 10) that is bedded in static or moveable disposition above the glass plate (5) which is to be modified, while the brush (9,10) has abrasive plastic threads (3) embedded with abrasive grains of synthetic diamond.

  • Patent number: 7666069
    Abstract: The present invention is directed to a wafer holder and a related wafer conveyor system. The wafer holder holds a wafer and moves horizontally within a chamber. A contact area between the wafer and the wafer holder is reduced, and potential contaminants generated by ear between components of the wafer holder are trapped by an airtight cover. Since the wafer holder moves horizontally while being fixed to a guide rail, the wafer conveyor system reduces friction between the guide rail and the wafer holder.

  • Patent number: 7628677
    Abstract: An automatic insulation block milling machine is disclosed. The machine combines a series of operations into a single, automatic, production-line machine. Blocks of rigid insulation material, such as cellular glass blocks, are fed into the automated machine. The blocks are first placed on an automatic programmed moving conveyor belt and are first cut on a pre-determined angle developed from the horizontal and vertical centerline of the block. This cut is made by an angled, vertical band saw mounted with its blade in the center of the moving conveyor, thus producing one angled side on each of the two cut blocks. The remaining three primary sides of the cut blocks are machined to create curved sectional blocks that are used to cover the outer surface of large bore pipe systems or other cylindrical items such as tanks.

  • Patent number: 7001249
    Abstract: Methods and systems are disclosed whereby the edges of a glass sheet may be beveled with minimal equipment down time. Preferably such methods and systems bevel the upper and lower edges along lateral sides of a glass sheet. In especially preferred embodiments, laterally separated pairs of upper and lower edge grinding assemblies are provided having respective upper and lower oppositely oriented tapered grinding wheels. A glass sheet may thus be moved in a generally horizontal conveyance direction between one of these pairs of upper and lower edge grinding assemblies so that respective upper or lower lateral edges of the glass sheet are brought into grinding contact therewith. Continually moving the glass sheet in the horizontal conveyance direction will therefore present the other lateral edge to the other pair of upper or lower edge grinding assemblies positioned downstream. As such, the other edge will then be beveled.

    Abstract: A method and apparatus for improved centering of a workpiece in a surfacing machine includes centering assembly having a plurality of individually movable biasing element sets, comprising an upper element and a lower element. Each element set is operatively connected to a closed circuit, double rod end hydraulic cylinder assembly which selectively and independently positions the element set responsive to the surface to the workpiece. The hydraulic cylinder assembly includes a valve. A pressure device is also operatively connected to each element set to provide a centering force. In use, as the upper or lower element of an element set is forced away from the centerline of the workpiece, the opposing element would automatically move the same amount when the valve is closed. When the valve is open, the upper and lower elements are free to move independently, allowing the centerline to be easily positioned as desired.
