A polypropylene strap for use in packaging articles. The polypropylene strap has a high tensile strength, a low elongation, a high rigidity, a high abrasion resistance, and flexible surfaces, and it is not easily split in the longitudinal direction. This strap has superficial layers stretched at a low draw rate of 1.2-3, and an inner portion stretched at a high draw rate of 10-18. The total thickn...

Orthogonal indicia of orientation of a drilling tool 22 at the end of a drill string 18 within a borehole 12 are measured by a pair of sensors at intervals of a first frequency. Pressure pulses indicative of the tool face angle are generated in the mud flow passing along the drill string 18 by means of a mud flow valve in response to each measurement, and the pressure pulses are sensed at the surf...

Disclosed is a primer composition which contains an isocyanate compound having one or more 1,3,5-oxadiazine-2,4,6-trione rings as an adhesion promoter, which is useful as a primer for bonding polyester plastics to the same or different substrates using an adhesive such as polyurethane, epoxy and polyolefin adhesives. When the surface of polyester plastics is treated with said primer prior to appli...
