Abstract: Шелковое тканое полотно известно и прославлено своими тактильными качествами. Однако недостатки шелка представляют собой его высокую цену, неудовлетворительную устойчивость при стирке и низкое сопротивление к определенным видам химической обработки. Таким образом, задача настоящего изобретения заключается в том, чтобы предложить шелкоподобное тканое полотно, которое преодолевает указанные недостатки. Согласно настоящему изобретению эту задачу решает предложение шелкоподобного тканого полотна (2), изготовленного из уточных нитей (4) и основных нитей (6), в котором по меньшей мере одна из уточных нитей (4) и основных нитей (6) содержит лиоцелловые волокна (8) или состоит из них.

Granted: 1983-12-08
Abstract: The hooper assembly is for transporting finely divided or granular material from a storage bin to a processing machine. It is located intermediate the discharger end of a mixing chamber and the processing machine entrance throat. The hopper itself is an inverted conical section, and has its open top sealable by a hinged closure. The hopper surfaces are pulled taut when it has been tipped by lifting from one side to empty it. This ensures no material of a different colour or type is left clinging to the wall sides when the machine is changed to a different run, as in the case of e.g. granulated plastics.
