Abstract: A process is disclosed for reclaiming a jelly-filled telecommunication cable. The process comprises the steps of cutting the cable into segments of jelly bearing insulated wires and forming the segments into a slurry heated to a temperature sufficient to soften the jelly. The slurry is milled thereby liberating insulation from the wires with a substantial portion of the softened jelly adhering to the liberated insulation. The jelly-bearing liberated insulation is then separated from the wires.

Abstract: 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.

Means (52) are also provided for securing the pair of covers (10) together about the clamp supports (22).

Abstract: A method and apparatus are disclosed for determining the presence of an out-of-service telephone in a building. The method comprises the steps of electrically isolating the building interior and exterior loops, determining if the electrical resistance of the interior loop is within a selected range, determining if the electrical capacitance of the interior loop exceeds a selected capacitance level, and generating a telephone present signal should either the determined resistance be within the selected resistance range or the determined capacitance exceed the selected capacitance level.

Abstract: Apparatus is disclosed for storing and displaying record albums comprised of a frame and means for mounting the frame to a wall. The frame has an upright side wall from which slide trays laterally extend and upon which albums may be positioned one behind the other to form a stack and later slid partially off the trays to reveal underlying stack members.

Abstract: A method and apparatus is disclosed for separating finely sized materials of diverse weights comprising a housing 8 having an opening 20 through which materials may be introduced for separation, an air intake 26 through which air may be introduced, and an air outlet 34 through which an air stream may exit. Means 53 are provided for forcing air into the housing 8 through the air intake 26 and out of said housing through the air outlet 34. A series of steps 10, 12, 14 is mounted within the housing 8 over which the materials may cascade. Means are further provided for channeling air introduced into the housing 8 through the air intake 26 into at least one air stream which passes between adjacent steps of the series of steps whereby the air stream may pass through the cascading materials and entrain the lighter materials.
