81	Process for reclaiming composite materials	US202283	1980-10-30	US4332677A	1982-06-01	Mieczyslaw Budzich; Forest G. Fitz, Jr.
A process for reclaiming composite materials that includes viscous and non-viscous constituents is described. The process comprises the steps of submerging the materials in a bath of liquid having a specific gravity greater than the viscous constituent but less than the non-viscous constituent, blasting the submerged materials with a gas or vapor heated to a temperature in excess of the melting temperature of the viscous constituent whereupon the viscous constituent is liberated from the non-viscous constituent and rises to the surface of the bath, skimming the viscous constituent from the surface of the bath, and emerging the non-viscous constituent from the bath.
82	Continuous recovery of base metal from insulated wire scrap	US602111	1975-08-05	US4022638A	1977-05-10	James H. Weet
A procedure and apparatus are shown for on a continuous, commercially practical basis recovering a non-ferrous base metal, such as copper or aluminum in the form of clean, bright metal pieces or bits and for enabling recovery of different non-ferrous coating metals, such as of lead, tin or alloys thereof, and under conditions in which a resin insulating coating may be present. Mechanical shredding means is used for reducing insulated wire to an aggregate containing bits, particles or pieces within a requisite size range, extraneous magnetics are removed, and the content of resin coating material is reduced under dry conditions to within a maximum of 2%. A preliminary step for attaining a less than 2% resin content importantly includes moving the aggregate as a vibration-activated, dry, fluid mass of substantially uniform thickness upwardly along a spiral path while separating the material into heavier and lighter portions, with the lighter innermost portion being recycled to further concentrate the metal bit content thereof and to further minimize the resin content thereof.After the resin content has been thus reduced, and the metal bit content maximized, the aggregate is again moved along a fluidized helical path in a vibration-activated stream of substantially uniform thickness upwardly, while applying a reactive chemical solution thereto in a counterflow path downwardly, with a substantially full area of exposure of the metal bits to the solution during its upward movement.
83	Method of selectively recovering vinyl halide insulation from insulated wire scrap	US543559	1975-01-23	US3975208A	1976-08-17	Stanley L. Tate; Bobby A. Rowland; Michael M. Blackstone
A process for selectively recovering vinyl halide insulation from mixed insulated wire scrap by selectively dissolving the vinyl halide insulation with a solvent at a temperature at which the solvent is a specific solvent for the vinyl halide and has no solvent effect upon other organic insulation material present in the mixed insulated wire scrap. The dissolved polyvinyl halide is recovered from solution in a dry granular state suitable for extrusion upon wire as insulation. The polyvinyl halide insulation is polyvinyl chloride, copolymers of polyvinyl chloride or mixtures thereof.
84	Process and apparatus for recovering metals from cables	US3650012D	1969-12-17	US3650012A	1972-03-21	GRAVEMAN FRED J
Aluminum is recovered from steel reinforced aluminum cable (ACSR cable) by first straightening the cable and thereafter cutting the strands of aluminum away from the steel core at the end of the cable so as to expose a short portion of the core. Next, the cable is severed so that the exposed portion of the core is disposed at the end of a relatively short segment of cable. The steel core is then withdrawn from the surrounding aluminum strands by passing its exposed portion through an opening and pulling it while the ends of the aluminum strands abut against the member in which the opening is formed. Finally, the aluminum strands, freed of the steel core, are introduced into a rotary shear which reduces them to pellet size fragments.
85	Process and apparatus for recovering metals from cables	US3612412D	1970-06-18	US3612412A	1971-10-12	GRAVEMAN FRED J
Cable comprising aluminum strands wound about a steel core is reduced to its separate metal components by cutting substantially through the aluminum strands at closely spaced intervals, but leaving the steel core intact. This frees small aluminum strand segments from the core and these segments may be reduced still further in a reduction mill. The core is wound into a roll after the segments are cut away from it. The aluminum strands are severed into the segments by blades having notches therein which are sized to fit around the core but not around the strands about the core. The blades may be mounted on revolving wheels or they may reciprocate.

94	INSULATION OF CONDUCTORS WITH IMPROVED SEPARABILITY FROM PROCESSED BROKEN STONE	EP07817392.9	2007-10-26	EP2087491A1	2009-08-12	VALENTA, Pavel; FIALA, Jaromír; SRANK, Zlatko; MASTNY, Libor; MECÍR, Pavel
The invention deals with insulation with improved separability from the processed broken stone designed as single- layer or multi- layer insulation surrounding an electric conductor where the principle is that at least one layer of the insulation is made of magnetic material and at the same time at least one layer is made of electrically non-conductive material. The magnetic main material component is produced on the basis of magnetite or ferrite or on the basis of noble earth elements in the oxidation degree II, or on basis of ferric oxide in the modification y-Fe2O3, or on the basis of powder iron, or on basis of magnetic alloy of iron or on the basis of a mixture or alloy containing the above mentioned magnetic partial components, or on the basis of magnetically hard materials of the AINiCo or FeCoCr type. The non-magnetic main material component is beneficially produced on the basis of plastic material, advantageously selected from the group of polymers or copolymers, mainly from the group of elastomers as silicone or butadienstyrene rubber or plastic materials as PVC, PE, PP or PTFE.

96	A PROCESS FOR NON-DESTRUCTIVE SEPARATION OF MIXTURES CONTAINING PLASTICS AND NON-PLASTICS SCRAP	EP83900023.9	1982-12-23	EP0097187B1	1987-04-15	RASMUSSEN, Erik
Sink/float separation of finely divided mixtures of scrap plastics and non-plastics materials, such as metal and glass, by addition of a liquid halogenated hydrocarbon being substantially chemically inert towards the components of the mixture, having essentially no swelling or dissolving effect on the plastics components and having an intermediate density adapted to the densities of the plastics and non-plastics components, preferably a chlorofluoro-substituted aliphatic hydrocarbon, such as 1,1,2-trichloro-1,2,2-trifluoroethane, and then the resulting non-sedimented and sedimented fractions are separated and, if desired, subjected to further separation treatments, while the halogenated hydrocarbon is recycled. The process is non-destructive and particularly useful for separation of finely divided scrap wire, glass or cable, such as PVC/Cu, rubber/Cu, PEX/Al, PVC/Al, PE/Cu or mixtures thereof. Addition of density-adjusting additives permits separation of various types of plastics and it is also possible to extract and recover additives, such as plasticizers.
97	Method of and device for recycling remnants of plastic-coated cables	EP84112699	1984-10-20	EP0144666A3	1986-06-11	Drzevitzky, Bernd
Die Kabelreste werden in ein Bad (15) eingegeben, das ein flüssiges Quellmittel enthält, welches die Kunststoffteile aufquellen läßt und brüchig macht. Anschließend an den Quellvorgang werden die Kabelreste einer Waschstation (25) zugeführt und mit scharfen Strahlen aus Sprühdüsen (32′) besprüht, wobei die Kunststoffmäntel der Kabelreste durch den Strahldruck zerkrümmelt werden. Die Kunststoffteile (33) werden durch eine Trennvorrichtung (31) von den Metalltei len (38) getrennt. Das Verfahren hat den Vorteil, daß keine chemische Umsetzung bei den Metallteilen und bei den Kunststoffteilen erfolgt und daß keine schädlichen Abgase entstehen.

99	A PROCESS FOR NON-DESTRUCTIVE SEPARATION OF MIXTURES CONTAINING PLASTICS AND NON-PLASTICS SCRAP	EP83900023.0	1982-12-23	EP0097187A1	1984-01-04	RASMUSSEN, Erik
Séparation par enfoncement/flottaison de mélanges finement divisés de matériau de déchets plastiques et non-plastiques, tels que du métal et du verre, par addition d'un hydrocarbure à halogénation liquide, sensiblement inerte chimiquement envers les composants du mélange, n'ayant essentiellement aucun effet de gonflage ou de dissolution sur les composants plastiques et ayant une densité intermédiaire adaptée aux densités des composants plastiques et non-plastiques, de préférence un hydrocarbure aliphatique à substitution chlorofluoro, tel que 1,1,2-trichloro-1,2,2-trifluoroéthane. Les fractions non sédimentées et sédimentées obtenues sont séparées et, si nécessaire, elles sont soumises à des traitements ultérieurs de séparation, l'hydrocarbure halogéné étant recyclé. Le procédé est non-destructif et est particulièrement utile pour la séparation de fil métallique, de verre ou de câble de rebut finement divisés, tels que PVC/Cu, caoutchouc/Cu, PEX/Al, PVC/Al, PE/Cu ou leurs mélanges. L'addition d'additifs d'ajustement de la densité permet la séparation de divers types de plastiques et il est également possible d'extraire et de récupérer les additifs, tels que des plastifiants.
100	Procédé de destruction de produits à base de matières organiques contenant du soufre et/ou des halogènes et/ou des métaux toxiques et applications de celui-ci	EP82420098.4	1982-07-13	EP0070789A2	1983-01-26	Bienvenu, Gérard; Regnault, Alain; Tournier, Hervé; Dubuc, Dominique
Ce procédé foumit de façon rapide et économique des pyroiysats exempts de soufre et/ou d'halogénes, par immersion de la matière à traiter dans un bain de sels fondus. Le bain est constitué essentiellement d'hdroxydes et/ou d'oxydes de métaux alcalins et/ou alcalino-terreux, seuls ou en mélange. Le bain peut contenir en outre des carbdnates, sulfates et chlorures alcalins et/ou alcalino-terreux. Il peut être régénéré dans certains cas par une oxydation in situ. Le procédé s'applique à la destruction par pyrolyse ou craquage thermique des déchets de matières plastiques ou de caoutschouc, et plus généralement de produits organiques contenant des halogènes et/ou du soufre et/ou des métaux toxiques.
