Title: Processing mixed waste plastic - in successively hotter extruder stages with interstage expulsion
IPC: B29C48/395
Filed: 1971-05-18
Abstract: A method of preparing mixed waste plastics for reuse in the plastics ind. is carried out as follows - the mixed granulate is fed into a first extruder where it is raised to a temp. sufficient to melt the lowest melting type of plastics contained in the mix, this melt then being removed; the remaining mixt. passes to another extruder operating at a higher temp., where the next lowest melting component is melted and again removed, and so on for further stages until an unworkable residue only remains. The prefd. appts. comprises a single shaft extruder constituted by the successive shafts of the successive stages, each shaft being conically widening in the flow direction; at the discharge (downstream) end of each stage, the barrel is perforated, so that the smelt from that stage is squeezed out laterally and removed from the extruder. The final, unworkable residue may be used as a cheap fill material for civil engineering works.

Title: Remelting furnace program control - of current and voltage combined with electrode motion feedback
Inventor: FAJN PAWEL IOELJEWITSCH
IPC: G05B19/12
Filed: 1973-03-28
Abstract: A programme control system for electroslag and vacuum arc remelting furnaces includes photoelectric programme control units for the remelting current, the electrode voltage, the active slag resistance or the furnace input. In addn. an inductive transducer converts the electrode motion into an electric signal for driving the motor for the electrode motion differential and the two motors for the chart feed of the programme control units. This enables the process to be controlled not only as a function of its duration (causing changes in current and voltage) but also of the electrode displacement. The result is a more stable function of the furnace, and an improved metal structure and surface condition. The removal of shrinkage cavities is facilitated and the scrap rate is reduced.
