Stitch bonded fabrics were found to be suitable substrates for coated abrasives when the fabric has a strength in the warp direction of at least 30 dekanewtons (daN) per centimeter (cm) of width, a fill yarn cover factor of at least 40%, and stitch yarns with a tensile strength of at least 0.5 daN. For substitution of the established commercial classes of abrasives known as X and Y weights, the fa...

Films comprising alpha-olefin polymers, such as polypropylene consisting essentially of recurring propylene units and having a substantial crystalline polypropylene content, and in particular isotactic polypropylene, are rendered poorly adhesive to the welding bars of automatic and semi-automatic machines conventionally used for the manufacture of containers, envelopes, bags, vessels and, in gener...

Reinforcements such as, for example, carbon fibers, are coated with a poly(arylene sulfide). The poly(arylene sulfide) is cured in place on the reinforcement. The reinforcement can be used in compositions such as, for example, poly(arylene sulfide) compositions.

The present invention relates to an enclosure member consisting essentially of solid, non-aromatic polymers that have a linear carbon to carbon backbone structure and have a plurality of free hydrogen atoms attached to the carbon atoms with a permeability to wet and dry solvents and fuels of less than 1/50, of the permeability of untreated enclosure members having a thickness of 1 mm, a portion of...

A stitch-through fabric includes a layer of diagonal or biased-extending filling yarn elements 196 to provide new aesthetic effects and multi- dimensional stability not previously known with this category of fabric. The yarns are laid by a carriage 154 driven along a path inclined to the fabric-forming direction of the machine and a layer of conventional filling yarns may also be supplied by a car...

The invention relates to method and apparatus for determining the flow rate of fluid in a well over an interval including zones where fluid is exchanged between the well and the formations through which it is bored. A logging sonde is used to measure the temperature of the fluid along said interval, and the flow rate is measured at least at the ends of the interval. Then for each depth, a flow rat...
