  • Patent number: 7878027
    Abstract: A glassware forming machine blowhead arm assembly includes a one-piece blowhead arm body having at least one longitudinal air passage and a plurality of lateral air passages connected to the longitudinal passage. A blowhead chuck is removably received in a first end of each lateral passage and a cap is threaded into the second end of each lateral passage spaced from the associated blowhead chuck. A spring is captured in compression between each cap and an associated blowhead chuck biasing the blowhead chuck in a direction out of the lateral passage and away from the cap. In an exemplary embodiment of the disclosure adapted for use in conjunction with so-called isolated finish cooling blowheads, there are first and second longitudinal air passages extending through the blowhead arm body separately from each other, and separate air inputs in the body respectively coupled to the first and second longitudinal passages.

  • Patent number: 7861557
    Abstract: The improved plasma torch for making synthetic silica includes use of nitrogen screen gas from outer quartz tubing to provide active environment isolation. In addition, the present induction plasma torch includes a ring disk for more compact but complete environmental protection (360 degree coverage). It also includes offsetting and switching the position of the chemical injection nozzles for allowing improved deposition in both directions, when operated in a horizontal mode. Further, the present induction plasma torch maintains laminar flow for the injected chemicals and the middle quartz tube is provided with a concave section for increasing the average enthalpy of plasma jet, thus improving the efficiency of the plasma torch. In addition, it may utilize more plasma gas inlets. It also includes chemical injection nozzles having a downward angular inclination.

  • Patent number: 7845193
    Abstract: Apparatus for opening and closing mold arms in a glassware forming machine includes a gearbox for mounting on a glassware machine frame, a cylinder housing suspended beneath the gearbox, and a cylinder disposed within the cylinder housing. The cylinder has a piston with an extending piston rod and a gear rack machined or otherwise formed in the piston rod. A first drive gear in the cylinder housing is coupled to the gear rack and a drive shaft extends from the first drive gear and the cylinder housing into the gearbox. A second drive gear is disposed in the gearbox and coupled to the drive shaft. Laterally spaced operating shafts extend upwardly from within the gearbox. Means including an idler gear couple the second drive gear to the operating shafts such that the operating shafts are rotated simultaneously in opposite directions by the cylinder, the gear rack, the first and second drive gears and the idler gear.

  • Patent number: 7632448
    Abstract: The invention relates to a method and device with which it is possible to arrange complicated shapes with considerable differences in height in wood fiber board, and in particular but not exclusively so called MDF (Medium Density Fiberboard). The deformation of the wood fiber board which can be achieved with the invention is known in the art as extusion, wherein a considerable plastic deformation takes place accompanied by flow and stretch of the material.

  • Patent number: 7588706
    Abstract: A method of improving hot tack and/or seal strength in a multi-layer film by selecting a first PE comprising at least one of mPE, LDPE or LLDPE to form a first layer and selecting a blend comprising a mPE and a PP to form an outer layer; and coextruding the first PE and the blend to form the multi-layer film comprising the first layer and the outer layer; wherein the inner layer comprises at least one component having a final melting point at least about 15° C. higher than a final melting point of at least one component of the first layer, wherein the multi-layer film has a maximum hot tack at least about 25% greater than a similar multi-layer film with 0-weight % of the PP in the inner layer.
