  • Publication number: 20210062436
    Abstract: Artificial turf system (10) including a primary backing layer (12) and a shock absorption component (20). The primary backing layer (12) has a plurality of artificial turf yarns (14) projecting upwardly from the primary backing layer (12). The shock absorption component (20) is composed of a sheet of three-dimensional random loop material 3DRLM (30). The sheet of 3DRLM (30) is in contact with the primary backing layer (12). The shock absorption component (20) includes (i) a cushioning layer (40) and (ii) a shockpad (50). The 3DRLM (30) in the cushioning layer (40) has an apparent density that is greater than the apparent density of the 3DRLM (30) in the shockpad (50).

  • Patent number: 9598626
    Abstract: The hydration of clays and shale in drilling operations may be inhibited by employing an aqueous based drilling fluid comprising a shale hydration inhibition agent having the formula: (I), R is an alkyl group having 1 to 6 carbons; R1 may be the same or different than R and is an alkyl group having 1 to 10 carbons or a hydroxy alkyl group comprising n number of carbons wherein n is an integer from 1 to 10 and n?1 hydroxyl groups; R2 is an alkyl group having 1 to 6 carbons; R3 may be the same or different than R2 and is an alkyl group having 1 to 10 carbons or a hydroxy alkyl group comprising n number of carbons wherein n is an integer from 1 to 10 and n?1 hydroxyl groups, with the proviso that R3 is not the same as R1; and X is an anion. The shale hydration inhibition agent should be present in the aqueous based drilling fluid in sufficient concentration to reduce the reactivity, such as swelling, of clays and shale when exposed to water-based drilling fluids.
