Abstract: There is described a twin-screw extruder in which there are provided a pair of die hole sets which are aligned with the extrusion paths from each screw. This arrangement allows all the extrusion path lengths from a plane perpendicular to the screw ends to the outer ends of the die holes to be substantially the same. Preferably two sets of cutter blades cut extrudate at the die hole outlets of each set. The blades are arranged on a pair of rotary assemblies, the axes of rotation of which are substantially coaxial with the axes of rotation of the extruder screws. Optionally a pressure chamber, capable of sustaining a pressure of less than ambient, is in gas tight communication with the outlet of the extruder to receive extrudate to enhance expansion of the extrudate.

Abstract: A shear mount assembly and a compression mount assembly are combined to control ride harshness of a shock absorber. The shock absorber includes a body and a shock rod having a hydraulically sealed portion within the body and a distally extending free portion. A mount assembly is connected at the free portion having both a compression mount and a shear mount therein. The shear mount absorbs low-input vertical loads transferred from the shock rod, and the compression mount limits vertical displacement of the shear mount and absorbs a medium-input vertical load. The shear mount and the compression mount are tuned by selecting the durometer, dimensions, and physical configuration of each mount.
