Abstract: A process according to which filaments are embedded in a thermoplastic substance. The filaments pass through a chamber which is filled with a thermoplastic substance under pressure and made viscous by heating and the filaments run over a number of return members, thus having the effect of embedding the filaments in a matrix consisting of the thermoplastic. On leaving the chamber, the filaments pass through at least one die with the matrix in which they are embedded. The pseudo monofilament thus formed is subjected to a twist and is coated with a sheath of wear-resistant thermoplastic substance.
Abstract: A method is provided for manufacturing a chemical mixture, such as a gasoline blend, which conforms to a set of regulations set by an outside public agency. The invention is directed to a set of regulations which require the manufacturer to prepare a master specification which sets control limits on the chemical characteristics of the chemical mixture and require that the master specification conform to a set of controlling criteria which are dependent upon such control limits--such as predicted exhaust pollution emissions from the burning of the subject gasoline blend.
