Embodiments of the present invention may provide methods and systems for recycling asphalt shingles (1) perhaps in a chemical solution (2) to provide oil free recyclable fiberglass (6), oil free recyclable sand (7), and even recyclable oil (8). The present invention may provide a screened tubular rotating equipment (16) may be at least partially immersed (18) in a tank (17) of a chemical solution (2) to treat the asphalt shingles (1).

Low-density thermoplastic expandable microspheres are disclosed. Various low-density structures, in particular, sandwich panels, based on foam prepared from the low-density microspheres, are also disclosed. Process of preparing low-density polymeric microspheres, per se, and the corresponding low-density structures, based on the microsphere foam, are also disclosed.

An automatic ring valve 10 comprising a valve seat 12 provided with a plurality of gas flow passages 14 arranged according to at least one annular row, at least a shutter 18 comprising at least one ring-shaped portion for selectively closing and opening the gas flow passages 14, wherein said ring-shaped portion of the shutter 18 comprises a fiber-reinforced matrix 40, at least one contrasting member for contrasting an opening movement of ring-shaped portion of the shutter 18, wherein said ring-shaped portion of the shutter 18 comprises a structural core 18A made by said fiber-reinforced matrix 40, and wherein at least a portion of said structural core 18A is covered by at least one primary layer 18B, designed to improve fracture and/or impact and/or wear resistance of said ring-shaped portion.

A filler-containing resin molded product with a surface which includes irregularities which are transferred from a mold cavity to the surface and have an arithmetic mean roughness of 0.8 μm or greater and 10 μm or less and a peak arithmetic mean curvature of 400 [1/mm] or greater and 900 [1/mm] or less.

It is an object of the present invention to provide a resin molded body capable of appropriately and easily improving strength compared to the prior art. The resin molded body according to the present invention includes first phases (21, 24) in which convex and concave parts extend in substantially linear directions (D, E), observed within a measurement range (A) of 5 μm×5 μm arbitrarily selected on a resin cross section and the first phases account for 50% or more. The first phases are preferably in a crystalline state. A second phase made of an amorphous substance (25) is preferably interposed between the first phases.

The direct-current cable includes a conductive portion; and an insulating layer covering an outer periphery of the conductive portion, the insulating layer containing cross-linked base resin and inorganic filler, the base resin containing polyethylene, a BET specific surface area of the inorganic filler being greater than or equal to 5 m.sup.2/g and less than or equal to 150 m.sup.2/g, and a mean volume diameter of the inorganic filler being less than or equal to 1.0 μm, the mass ratio of the inorganic filler with respect to the base resin being greater than or equal to 0.001 and less than or equal to 0.05, and the cross-linked base resin being cross-linked by a cross-linking agent containing organic peroxide.

A method is provided for treating the outer surfaces of a plurality of glass bubbles. That method includes loading a plurality of glass bubbles into a processing vessel having a roughened lining and displacing the processing vessel so that the plurality of glass bubbles move against the roughened lining to thereby roughen the outer surfaces. Alternatively, or in addition, the glass bubbles are subjected to air plasma treatment to increase the surface energy of the glass bubbles.

A polyamide resin composition for a vibration-damping material, containing a polyamide resin, a plasticizer in an amount of from 7 to 35 parts by mass, and one or more members selected from the group consisting of plate-like fillers and acicular fillers in an amount of from 15 to 80 parts by mass, based on 100 parts by mass of the polyamide resin. The polyamide resin composition of the present invention can be suitably used as a vibration-damping material for a material for audio equipment such as, for example, speakers, television, radio cassette players, headphones, audio components, or microphones, and manufactured articles such as electric appliances, transportation vehicles, construction buildings, and industrial equipment, or parts or housing thereof.

A reel based tensioning device includes a housing, a spool that is rotatably positioned within the housing, and a knob member that is operably coupled with the spool to cause the spool to rotate in a first direction within the housing and thereby wind a tension member about the spool. The reel based tensioning device also includes a load holding mechanism that is coupled with the spool and that is configured to rotate the spool in the first direction within the housing and to prevent rotation of the spool in a second direction to prevent unwinding of the tension member from about the spool. The reel based tensioning device further includes an audible component that is configured to produce an audible noise responsive to operation of the knob member to signal an adjustment of the tension member.

The present invention provides a resin material composition including 25 to 65% by mass of a thermoplastic polyolefin resin, 0.5 to 22% by mass of a glass wool, and 5 to 35% by mass of a thermoplastic elastomer.
