A safety ski binding comprises a releasable front jaw (11) engaging one end of the ski boot (15) and a heel jaw (12) which engages a second end of the ski boot (15). A heel jaw housing (16) is mounted longitudinally displaceably in longitudinal guides (13) affixed to the ski. Preferably, there is at least some vertical and horizontal play between heel jaw housing (16) and longitudinal guides (13)....

A non-invasive method and apparatus are described for measuring the oxygen concentration in the infected cells of the nodules of nitrogen fixing plants in the laboratory or field. In many cases, this information can be used to estimate the nitrogenase activity, and therefore the nitrogen fixation rate, in these nodules since recent studies have shown that the oxygen concentration limits and contro...

A polyester film having a nodule surface is disclosed. The acrylic coating is preferably a crosslinked composition having a relatively high methyl methacrylate content and specific surfactants. The acrylic coating composition is applied as an aqueous dispersion to polyester film, preferably after corona treatment of the polyester film. The nodule surface reduces the coefficient of friction of the ...

The present invention relates to a process for the preparation of polyurethane rigid foams having a low thermal conductivity, comprising reacting: a) organic and/or modified organic polyisocyanates with, b) at least one higher molecular weight compound having at least two reactive hydrogen atoms, and optionally c) lower molecular weight chain extending agents and/or crosslinking agents in the pres...

Self-extinguishing polyurethanes are obtained by stepwise polyaddition of diisocyanates or polyisocyanates with polyols with the addition of a flameproofing agent comprising a phosphorus component and a nitrogen component as synergists. While the phosphorus component used is an ammonium polyphosphate which is sparingly soluble in water and, if desired, has been microencapsulated with a melamine/fo...
