Fabrics in accordance with the invention are characterized by densely woven bodies of substantial thickness, in which individual warp yarns define angled paths traversing a principal portion of the wall thickness. The warp yarns and lateral fill yarns completely interlock the structure in non-laminar fashion. Seamless thick walled bodies having selectable shapes are woven by methods in which fill yarns are circumferentially fed under tension between spaced and independently controlled warp yarns...

Binders containing metal oxide nanoparticles and a co-resin of phenolic resin and aminoplast resin, and electrophotographic imaging member undercoat layer containing the binders.

A series of roofing shingles (200, 240, 260, 280) are disclosed which have multiple tabs across the exposed width of the shingle. A polymer foam layer is bonded to an asphalt shingle material to form the roofing shingle. The polymer foam is thicker at certain of the tabs than others to provide a pleasing layered appearance to the roof. The tabs can also be varied in width and length relative to adjacent tabs.

A group of collated book signatures or other layers of paper are cut with bevel edged bits spaced around the circular periphery of a wheel by feeding the paper in the same direction as the teeth rotate such that an exposed side of the paper advances in a plane intersecting normal to the circular radius more than half an inch from the outer end of the radius, and such that the bevelled outer corner of the cutting edge enters through the paper plane first and with the edge inclined away from the p...

A thick-film resistor paste comprised of a resistor composition dispersed in an organic vehicle, the resistor composition containing at least one of RuO.sub.2 and a Ru composite oxide as a conductive material, a glass composition, a titanate compound of an alkali earth metal of any of BaTiO.sub.3, CaTiO.sub.3, and SrTiO.sub.3, a metal material, and further optionally CuO and Cu.sub.2O as an additive, the formulation of the resistor composition optimized in accordance with the required resistance...

A thick walled pressure vessel having a tubular wall is prestressed by bending to resist extreme external pressures, the bending being applied by the external pressure being resisted. The tubular or cylindrical wall contains internal axial cuts which divide the wall into axial sectors with faying surfaces therebetween so that the application of external pressure decreases the curvature of the sectors to prestress them.

A composition including an aprotic polar solvent such as DMSO, a non-protic water-soluble ether, a water-soluble thickener selected from acrylic acid polymers and an aliphatic amine having 6-20 carbon atoms.

A thick film resistive heating element having a thick film resistive track applied to the surface of an electrically insulative substrate. An encapsulating insulating layer is applied over the track to protect it while an area of the element is left uncovered by the encapsulating layer so as to define a window. A portion of a temperature sensitive control device is then placed in direct contact with the track and/or the electrically insulative substrate through the window. The window in the elem...

Thick opaque ceramic coatings are used to protect delicate microelectronic devices against excited energy sources, radiation, light, abrasion, and wet etching techniques. The thick opaque ceramic coating are prepared from a mixture containing phosphoric anhydride, i.e., phosphorous pentoxide (P.sub.2 O.sub.5), and a pre-ceramic silicon-containing material. It is preferred to also include tungsten carbide (WC) and tungsten metal (W) in the coating mixture. The coating is pyrolyzed to form a ceram...

A method of making a decorative veneer panel having the appearance of antique, solid, planked, hand-planed wood wherein one-eight inch veneer sheets are adhesively applied to opposite sides of a fiberboard panel, one of the veneer sheets being of high quality wood and preferably including a decorative veneer strip, cutting spaced, parallel, flat bottomed grooves in the sheet of high quality veneer to give the appearance of a plurality of separate boards, and hand planing the raised faces of the ...
