Abstract: Multi-chamber containers with a dispenser/doser portion are blow molded as a single integral piece. Each chamber can then be fitted with dip tubes with a dip tube fitment forming a seal in the transition of the container body to the dispenser/doser portion. The dividing webs in the container which form the container into multiple chambers are continued up into and through the dispenser/doser portion. The webs of the container body are of a thickness so that they flex upon a compression force being applied to the container walls. This compression force flows liquid in each chamber of the container body up through the dip tubes and into the dispenser/doser portion.

Abstract: An injection nozzle for use in an injection molding apparatus including a generally annular base portion which supports a generally cylindrical hollow side wall portion. The hollow side wall portion terminates at its upper end portion in an inwardly beveled heat transfer control portion. The beveled heat transfer control portion terminates in an angled mating portion which is of complementary angle to the angled mating surface of an injection nozzle accepting recess in the injection mold portion of the apparatus. The injection nozzle structure provides for controlled heat transfer control from the sprue portion of an injection molded parison to prevent crystallization in the sprue portion of the parison.

Abstract: A method of making an electric conductor wherein a plurality of glass strands are coated with a thermally curable liquid dispersion of conductive particles and the strands are heated to thermally cure the liquid dispersion. The method includes grouping the wetted strands in a roving and winding the roving about rotating heated drums, which flattens the roving into a ribbon and cures the liquid dispersion on the strands. The conductive roving is spirally wrapped with a non-conductive strand into a cylindrical core and then encased in a semi-conductive overcoat.
