Abstract: A seamless, composite belt that is designed to maintain a substantially flat surface in the span between two rollers. The belts typically have one or more polymer layers, including the polishing layer, and one or more supporting woven or non-woven layers. The belts have the necessary balance between down-cupping and up-cupping forces achieved by: 1) varying the relative thickness of the different polymer and supporting layers in the belt, 2) varying the relative hardness or rigidity of the different layers in the belt, 3) varying the temperatures at which the different layers are formed, 4) varying the compositions of supporting layers, and 5) prestressing one or more of the composite layers. The belts are particularly useful in chemical mechanical polishing of semiconductor wafers.

Abstract: PURPOSE: To obtain a polyolefin resin composition excellent in heat and aging resistances and useful for films for self-adhesive tape substrates of good workability by mixing a base comprising a specified olefin resin with a high-mol. wt. hindered phenol antioxidant and a zinc compound. CONSTITUTION: A resin composition prepared by mixing 100 pts. wt. resin base comprising at least one member selected from among a polyethylene, an ethylene/vinyl acetate copolymer, an ethylene/alkyl acrylate copolymer, an ethylene/alpha-olefin copolymer and a mixture thereof with 0.1-10 pts. wt. high-mol. wt hindered phenol antioxidant and 1-20 pts. wt. zinc compound. Examples of the zinc compound to be used are desirably inorganic compounds and include zinc borate and zinc oxide. As the high-mol. wt. hindered phenol antioxidant, one having a mol. wt. of 500 or above is particularly desirable from the viewpoint of nonblooming properties, etc.

Abstract: A caulking tool (20) comprises mechanisms (24, 25, 26, 27) for temporarily securing the tool to a filter plate and a pivotally operable caulking body (29, 30, 31) which urges a caulking rope into a groove in the filter plate so as to capture a part of the filter cloth therein. This secures the filter cloth to the filter plate.

Abstract: In a seam, for example, for paper machine clothing, interdigitating seaming loops (13, 14) embrace deformable yarns (17) inserted between the last cross-machine direction yarns (15a) and the opposed seaming loops (14, 13). Alternatively, an insert may be in the form of a ladder-like member (30) comprising one or more cross-machine direction members (31, 32, 33) and a multiplicity of machine direction members (34) extending beyond the members (31, 32, 33) to locate the seaming loops. Also possible is the use of a strip or tape of foamed or foamable material.

Abstract: A method of manufacturing a polymer pore filter for filtering kaolin particles from an aqueous medium, comprising the steps of: coating and partially impregnating at least one face of a woven polyester textile substrate with a polyether based polyurethane polymer; coagulating the polymer by heating in the presence of a coagulant; and forming the polymer simultaneously with or immediately after coagulation.

Abstract: A diagnostic system for a jacquard machine having a plurality of heald hooks (16) moveable between at least two discrete shed positions, the system including visual sensing means (30) for producing a visual image of hooks (16) located at one of said shed positions during each weaving cycle, and control means (49) for comparing said visual image with a predetermined shed pattern for each corresponding weaving cycle in order to determine whether or not all the appropriate hooks have been selected to define the required shed pattern.

Abstract: A multifilament pintle wire comprises a polyolefin material optionally in combination with another material.

Abstract: A pair of filter cloths including a feed passage connector for a plate-type filter press is disclosed herein. The filter cloths include first and second tubular members each having opposed first and second free ends and through bores extending continuously from the first free end to the second free end of each of the first and second members. The first free end of the first member is connected to the first filter cloth with the respective cylindrical bore in coaxial alignment with the first feed opening and the second free end of the second member is connected to the second filter cloth. A third tubular member is provided having opposed third and fourth free ends and a radially outer surface and a central bore defining a feed passage. The radially outer surface of the third member is snugly received coaxially within the through bores of the first and second members to sealingly interconnect the first member to the second member.

Abstract: A temporary seaming aid for use in seaming a dryer fabric, comprising complementary parts (39) attached to two portions (31, 32) of a dryer fabric. The complementary parts are adapted for cooperation and enable the fabric ends which have interdigitating formations (33) thereon to engage. Engagement of the interdigitating formations allow a pintle wire (34) to be inserted therein to form a flexible joint resulting in seaming of the dryer fabric. The entire temporary seaming aid can easily be removed once the fabric ends are joined.

Abstract: A multi-layer fabric with paperside to lower surface weft ratios of greater than 1 in which all paperside weft yarns interlace with the warp yarns in an identical manner. The paperside weft yarns intermittently buttress against adjacent paperside weft yarns and possess an average lateral crimp ratio of greater than 1.62 giving a fabric having an air permeability of less than 275 c.f.m. at 1/2 inch water pressure.

Abstract: A phase separation apparatus such as a filter element or papermaking belt comprises an ormocer which provides abrasion resistance, cleanliness and stability.

Abstract: A method of coating an ormocer (organically modified ceramic) on a phase separation surface of a roller of a phase separation apparatus to facilitate phase separation.

Abstract: A method of coating an ormocer (organically modified ceramic) on a phase separation surface of a filter of a phase separation apparatus to facilitate phase separation.

Abstract: A dual purpose transfer printing and laminating blanket (18) has an endless woven base fabric (28) having at least one layer of fluoropolymer coating material (32, 33) applied thereto. A bonding layer is applied to each side of the base fabric, to bond the at least one layer to the base fabric.

Abstract: A method of coating an ormocer (organically modified ceramic) on a papermachine clothing.

Abstract: A papermaking fabric primarily for use as a press felt comprises basalt fibers.

Abstract: A Jacquard mechanism for creating a shed in a loom has a plurality of hooks operative to be connected, optionally via one or more other bodies, to yarns in a loom. The hooks are movable between a first position and a second position. A griffe is provided, the griffe being movable along a path so as to engage the hooks when the hooks are in the first position. The Jacquard mechanism also has a plurality of solenoids, each solenoid having a plunger operative to directly engage a hook. Movement of the plunger causes an associated hook to move to the second position wherein it will not be engaged by the griffe as it moves along the path.

Abstract: A papermachine clothing cleaning apparatus has a fluid injection nozzle with an apertured plate (14). The injection nozzle directs fluid onto the papermachine clothing (11) in order to clean the clothing. The areas of papermachine clothing that are adjacent the areas of clothing being impacted by the fluid are located in a press formed by the apertured plate (14) and a body (15) provided at the opposite surface of the fabric (11).

Abstract: A dewatering process in which a product comprising water and other materials is simultaneously subjected to compressive mechanical forces and electro-osmosis using a belt (12) having a plurality of connected spiral yarns and, at least in part, electrically conductive material thereon.
