摘要： Hose structure suitable for transport of highly abrasive media including at least two concentric tube layers of elastomeric material. The radially innermost tube layer material is of greater abrasion resistance than a tube layer radially outwardly thereof. A radially outer tube layer material is of greater resilience than that of the radially innermost tube layer. The tube layers may be made visually distinguishable, for example, by being of different colors, so as to serve as a wear indicator.
摘要翻译：软管结构适用于输送高磨损介质，包括弹性材料的至少两个同心管层。径向最内管层材料比其径向向外的管层具有更大的耐磨性。径向外管层材料具有比径向最内管层更大的弹性。管层可以在视觉上可区分，例如通过不同的颜色，以用作磨损指示器。

摘要： A woven fabric belt having a coating of polyurethane on each face and extending through the interstices of the fabric. The polyurethane is the reaction product of a polypropylene ether glycol of 4,4'-methylene di(cyclohexylene isocyanate) cured with p,p'-methylene dianiline and having at least one face of said belt covered with the polyurethane having walnut shell powder incorporated therein.

摘要： A hose structure resistant to pressure and vacuum as well as kinking or collapsing which exhibits good recovery from crushing includes in its wall structure elastomer embedded reinforcing cords extending in opposite hand helical patterns about the hose axis and a filler layer of elastomeric material having a thickness from about one fifth to about one fifteenth of the mean radius of the filler layer from the hose axis. The filler layer elastomeric material is of high tensile modulus and hardness and preferably includes short length fibers dispersed throughout oriented predominantly generally in the circumferential direction of the hose.
摘要翻译：耐压力和真空的软管结构以及扭曲或塌陷，其表现出良好的破碎恢复，包括在其壁结构中弹性体嵌入的加强帘线围绕软管轴线以相反的手螺旋形图案延伸，并且弹性体材料的填充层具有从约为软管轴线上填料层平均半径的五分之一至约十五分之一。填料层弹性体材料具有高拉伸模量和硬度，并且优选地包括分散在主要通常在软管的圆周方向上定向的短长度纤维。

摘要： A woven fabric belt having a coating of polyurethane on each face and extending through the interstices of the fabric. The polyurethane is the reaction product of a polytetramethylene ether glycol of 4,4'-methylene di(cyclohexylene isocyanate) cured with m-phenylene diamine and having at least one face of said belt covered with the polyurethane having walnut shell powder incorporated therein.
