Abstract: Non-food plant biomass is subjected to hot-water extraction in a pressurized vessel at an elevated temperature up to about 250° C. and at a pH below about 7.0, to yield an aqueous extract containing hemicellulosic components, other wood-derived compounds, and a lignocellulosic residue. The separated aqueous extract or liquor is purified and concentrated through a multi-step process producing fermentable sugars. At each stage, inhibitory chemicals such as acetic acid, lignin, and furfural are separated and eventually recovered as commercial chemicals. The lignocellulosic residue may be further processed, as a material with enhanced resistance to sorption of water, for manufacture of improved pulp and paper, construction materials, pellet fuel, and/or other useful products.

Abstract: A transmission with a load brake has a ball spline and a stabilizer ring for reducing chatter, a seal for preventing leakage, and an adjustment mechanism for extending the effective life of the brake disk stack. In the past, transmissions equipped with Weston brakes have experienced significant problems with instability and chatter. The present invention overcomes the problems of instability and chatter by introducing a ball spline at the junction between the output shaft and the loading assembly. The ball spline reduces friction caused by the axial movement of the output cam of the loading assembly. Also, the invention introduces a stabilizer ring around the loading assembly to reduce instability and chatter caused by the angular and transverse movement of the loading assembly. The invention also may also utilize a fluid damper in place of the stabilizer ring to reduce instability and chatter caused by the angular and transverse movement of the loading assembly.
