Abstract: Methods and systems for pelletizing high melt flow polystyrene are described herein. The method generally includes providing a polystyrene including a melt flow index of about 16 g/10 min to about 34 g/10 min; extruding a strand of the polystyrene through a die head, wherein a temperature of the polystyrene at the die head is from about 370° to about 430° F.; and moving the strand through a bath, wherein a temperature of the bath is from about 95° to about 145° F.

Abstract: A method of making a stainless steel composite door is accomplished by forming an oversized composite core by gluing a sheet of lightweight plywood to a sheet of brushed metallic laminate formed of a layer of metal and phenolic plastic. The thus formed core is cut to form an undercut step through only a portion of the plywood section, leaving the laminate intact. A pan is then laid down on a flat table with flanges pointing up. One-quarter inch thick spacer pads are placed in each of the four corners of the pan. The oversized metallic laminated core, with an undercut step, is placed on top of the pan and centered. Overhead clamps are tightened to hold the core in place in the pan. The metallic laminated core is routed by a trim router having a rotatable bearing and a cutting bit, with the bearing having a lesser radius than the router bit. The difference in radii between the bearing and the router bit is equal to the thickness of the flanges of the pan.

Abstract: A drive train comprises an internal combustion engine, a clutchless gearbox, which can be shifted by means of an electronic control unit and by means of actuating devices, without a mechanical synchronizing device, and a hydrostatic gearbox with a hydraulic pump and a hydraulic motor, which are connected in a closed circuit. The rotational speed of the hydraulic motor being controllable in dependence on a control signal to the adjusting device of the hydraulic pump and/or to the adjusting device of the hydraulic motor. The control unit calculates the control signal by means of setpoint input via an accelerator pedal or as a function of the rotational drive speed of the internal combustion engine, with shifting of the transmission stages being possible by means of the actuating devices.
