Disclosed is a multiple machining apparatus for, upon receiving a plastic cylindrical work piece therewithin, performing multiple machining operations thereon. The apparatus comprises a rotary fixture capable of rotation; the rotary fixture comprises a proximal means for snugly holding a proximal portion of the work piece, and a distal means for holding substantially the rest of the portion of the work piece. The apparatus further comprises a movable table comprising a blade holder for holding a plurality of blades, each of which corresponding to a machining operation, the movable table and thereby the blade holder capable movement along X, Y and Z axes. The multiple machining operations are executed as the work piece is rotated and with the blades working against the rotating work piece.

The purpose of the present invention is to provide an inorganic fiber laminate having improved uniformity of surface density, as well as provide a vacuum insulation material using the same, and a manufacturing method for the same. The present invention relates to an inorganic fiber laminate (10) at least including a first inorganic fiber mat (1) that has a high-surface-density section (1a) and a low-surface-density section (1b), and a second inorganic fiber mat (2) that has a high-surface-density section (2a) and a low-surface-density section (2a), wherein the high-surface-density section (1a, 2a) of the first inorganic fiber mat (1) and/or the second inorganic fiber mat (2) are/is laminated on the low-surface-density section (1b) of the first inorganic fiber mat (1), and the high-surface-density section (1a, 2a) of the first inorganic fiber mat (1) and/or the second inorganic fiber mat are/is laminated on the low-surface-density section (2b) of the second inorganic fiber mat (2).

Disclosed are filter media packs having a single layer of a high loft filter media and a single layer of a low loft filter media, the filter media pack characterized by the absence of oil added to the filter media pack, the filter media pack capable of filtering air laden particulates from an air stream at greater than 94% efficiency at air stream flow rates of between about 100 feet per minute and 3000 feet per minute. Also disclosed are filter assemblies formed from the filter media pack, and methods of using the filter assemblies.

A structure of phosphorous-containing functionalized poly(arylene ether), a preparation method thereof, and a composition prepared therefrom are provided. The curable (cross-linkable) composition includes an unsaturated monomer and a phosphorous-containing functionalized poly(arylene ether) having a polymerizable group and a molecular weight between 500 and 20,000. The composition provides excellent fluidity and fast curing rate. After curing, the composition exhibits excellent low dielectric coefficient and dielectric loss, high heat resistance and flame retardancy. It is suitable for prepregs, laminated sheets for printed circuits or the like.

A tester for bonded composite materials uses a magnetic source to generate a response signal from wires infused in an adhesive used between layers of the composite material. Acoustic or magnetic response signals, separately or in combination, can be received and analyzed to detect stresses in wires indicative of voids in the adhesive or other defects affecting the bond quality between layers of the composite material.

The apparatus further consists of a movable table with a blade holder for holding a plurality of blades, each of which corresponding to a machining operation, the movable table and thereby the blade holder is capable of movement along X, Y and Z axes. The apparatus performs multiple machining operations on the work piece by virtue of the rotation of the rotary fixture, rotation of the blades, and the movement of the movable table, working against the rotating work piece.

In-line processes for producing scrubby substrates, and related scrubby substrate cleaning articles. The process may include melting a polymer resin material, and extruding or otherwise dispensing the molten polymer resin material through one or more orifices of a heated nozzle, into a stream of hot inert gas, which attenuates the molten resin, so that the resin forms into elongated globules (rather than fibers or filaments). Such globules may have irregular cross-section and/or irregular thickness along a length of the globules. Alternatively, the molten resin may be formed into substantially continuous or discontinuous string or chain pattern of abrasive fibers, exhibiting a high frequency, low amplitude substantially linear pattern on the base substrate. In either case the globules or abrasive fibers are collected onto at least a portion of a base substrate layer to form a scrubby substrate that is more abrasive than typical meltblown materials.

The example of the vehicular interior trim according to the present application is multilayer structure including at least a base material and a skin layer. The multilayer structure is configured to satisfy the relationships in the following expressions (1) and (2), where RSm (mm) is the average surface roughness of the base material in the horizontal direction, E1_80 is the Young's modulus of the base material at 80 C., d1 (mm) is the thickness of the base material, E2_80 (GPa) is the Young's modulus of the skin layer at 80 C., and d2 (mm) is the thickness of the skin layer. Expression (1): Expression (2):
0.15<RSm/(E2_80d2)(1)
RSm/((E1_80d1){circumflex over ()}2+(E2_80d2)2)<135(2).
