Filed: 1928-04-30
Abstract: 317,506. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). April 30, 1928. Coking processes. -Organic substances which are volatilizable at an elevated temperature are recovered from mixtures with solid material by gradually raising the temperature while allowing the material to flow in a viscous condition and in thin layers over a surface, the solid residue being removed continuously. The material is fed at a to the surface of a cone b rotating on ball bearings d, scrapers l mounted within an outer shell k serving to pass the solid residues to a chamber m, whence scrapers n convey them to a chamber o. Heat is supplied from a burner f within an inner shell e, the gases of combustion passing by the path shown into the reaction space between the cones b, k. Auxiliary scavenging gases may be admitted at p and the distilled substance passes off at q.

A composite melt-extruded thermoplastic filament or bristle having a diameter of at least 0À010 inch comprises a melt-extruded inner core of a thermoplastic synthetic resin and a melt-extruded concentric outer sheath of a second thermoplastic resin, the two thermoplastic resins having different properties, characteristics and chemical composition. The core and sheath may have been oriented. The core may consist of plasticized polyvinyl chloride and the sheath may consist of unplasticized polyvinyl chloride. The overall diameter of the filament may be up to 0À150 inch, and that of the core a diameter of 0À003 to 0À014 inch, while the sheath may have a thickness of 0À001 to 0À035 inch. The core may have a cellular structure. The term polyvinyl chloride is defined as including both homopolymers of vinyl chloride and vinyl chloride copolymers in which vinyl chloride predominates. The copolymer may be the polymer of vinyl acetate or of vinylidne chloride. When the inner core consists of plasticized polyvinyl chloride it generally contains about 15 to 60% and preferably 25 to 45% by weight of any conventional P.V.C. plasticizer. The core and sheath portions of the composite filaments may or may not be bonded to each other. The core may consist of polyethylene made by the high-pressure process and the sheath may in this case be nylon. The composite filaments may be made by means of an apparatus comprising an extruder having a cylinder 1 (Fig. 1), a screw 2 and a die 3 connected to the cylinder 1 by the internally threaded ring 7. The cylinder 1 and die 3 are provided with electrical heating jackets 15 and 16, respectively. Unplasticized P.V.C. material S is forced by the extruder 1 through holes 9 in a mandrel 5 and is extruded through the annular extrusion orifice between the hole 4 in the die 3 and the tip of the mandrel 5.

Filed: 1941-10-10
Abstract: 589,127. Impulse generators. BLUM. LEIN. D. (Representative of BLUMLEIN, A. D.). Oct. 10, 1941, No. 13065. [Class 40 (v)] An impulse generator comprises a storage device consisting of capacity and inductance and a switching device and a load so arranged that the closure of the switch redistributes the energy so that the polarity of the voltage across the capacity is reversed and the energy dissipated in the load. The load in the case of a single storage device is unilaterally conducting. A second storage device may be used with the load connected between the devices, so that after the redistribution of the energy the voltage is applied in series with that in the second storage device to the load. Fig. 2 shows a condenser 1 charged through a diode 5 and associated with an inductance 2 feeding a magnetron 3 with switching effected by impulses applied to gas discharge device 4. Alternatively charging may be effected through an inductance which may form with the capacity a circuit resonant at the applied frequency. The storage device may comprise a delay network instead of a simple inductancecapacity combination in which case the load and the switch may be connected to opposite ends of the network Fig. 1 (not shown). Fig. 4 shows an arrangement in which a further storage device, the delay network 1a, 2a is connected in series with the load 3 and charged simultaneously with the network 1, 2, so as to increase the voltage applied to the load. The charging is effected from an alternating supply through a unilateral conductor and the further storage device may be charged through a terminated delay network. 1b, 2b or through an impedance, e.g. a choke in parallel with the unilaterally conducting load, Fig. 3 (not shown).
