A modular support system for organic filter material, compost material or other material is formed of a multiplicity of polygonal bed platform modules with planar top surfaces, the modules arranged side by side contiguously to form a bed platform which is elevated above a base surface. The method comprises providing primary and secondary road wheel position sensors configured to generate road wheel angle signals indicative of a road wheel angle to a microprocessor. Based on the partial query, the search engine creates a set of predicted queries. This separating nozzle is furnished with a nozzle channel, wherein the nozzle channel is furnished with one or several twisted grooves at the circumference of the nozzle channel and wherein the number of the twisted grooves and the diameter and the length of the nozzle channel are placed in such ratio that the separating jet subjected to pressure is rotated. The plate is pressed by the injection pressure of the resin to come into close contact with the stopper and to create a seal which prevents leakage of resin into the slot.
