An optical glass comprising SiO2, B2O3 and La2O3 and one or more oxides selected from the group consisting of ZrO2, Nb2O5 and Ta2O5, having a refractive index of 1. The wet chips in a fluid transport travel in a trough to a shredder having a shredder assembly made up of a plurality of combs that cooperate with a plurality of sizing members with at least a portion of the combs and members being positioned within the trough. In addition the compositions incorporate the organofunctional group R as part of a O3SiR-siO3 unit in the framework of the compositions. The vapor passages within the discriminator, cylinder head andor manifold are sized for receipt of spring actuated ball’s to open andor close the vapor passages during suction andor discharge of refrigerant vapor or liquid by the compressor. The companion application window shows the windows from multiple applications as essentially one application or window on the graphic user interface. Dry gas under pressure is supplied to a filament path leading from a material supply to a liquifier, creating an active moisture barrier along the filament path.
