摘要： The invention relates to a structure, such as a cooling tower, comprising a waisted tubular envelope consisting of a membrane made of a material which is capable of supporting tension in all directions in its plane. The membrane is pre-tensioned and carried with its tubular axis upright from a support which provides the vertical component of the pre-tensioning.

摘要： A waisted envelope for tubular building structures, such as cooling towers, is supported by way of a supporting structure, joined with its top end and responsible for a pulling or pretensioning force, on a system taking up the vertical component of the pulling force. The envelope is designed as a membrane made of material designed for supporting tension within its plane in all directions.

摘要： This invention relates to large reflectors in particular those used for antennas, solar mirrors and the like having a concave reflector surface. The reflector comprises a membrane having a reflective surface, which membrane in its initial planar state is capable of being deformed in all directions in its plane. The reflector is mounted in a gas-tight chamber as one wall thereof and a differential pressure is exerted across the membrane either by way of increased or reduced pressure applied to the chamber. When deformed to concave shape, such deformation may be sufficient to cause permanent deformation of the membrane to its concave shape when it has been stretched beyond its elastic limit and plastic deformation has occurred. The reflector may then be used removed from the gas-tight chamber and when so used is preferably backed with a rigid foam backing. Alternatively, the differential pressure applied to the membrane may be insufficient to permanently deform the membrane to its concave shape and a rigid foam backing or the like applied thereto while it is in its deformed concave shape. In this circumstance the rigid foam maintains the reflector in its deformed concave shape. Still further, the differential pressure across the membrane whether sufficient to cause permanent deformation or not may be maintained during use of the reflector. In this circumstance the gas-tight chamber becomes a supporting structure for the concave membrane and the differential pressure maintains the shape. A rigid ring serves as the circumferential edge of the chamber and the deformed membrane is maintained in tension by the differential pressure.
摘要翻译：本发明涉及大型反射器，特别是用于具有凹面反射器表面的天线，太阳镜等的大型反射器。反射器包括具有反射表面的膜，其初始平面状态的膜能够在其平面中的所有方向上变形。反射器作为其一个壁安装在气密室中，并且通过施加到腔室的增加或减小的压力跨膜施加压差。当变形为凹形时，当其被拉伸超过其弹性极限并且已经发生塑性变形时，这种变形可能足以导致膜永久变形到其凹形。然后可以使用反射器从气密室移除，并且当使用这种反射器时，优选地用刚性泡沫背衬支撑。或者，施加到膜上的压差可能不足以使膜永久地变形成其凹形，并且在其变形的凹形状下施加到其上的刚性泡沫背衬等。在这种情况下，刚性泡沫将反射器保持在其变形的凹形状中。此外，在反射器的使用期间，可以保持横跨膜的压差是否足以引起永久变形。在这种情况下，气密室成为凹形膜的支撑结构，并且压差维持形状。刚性环用作室的周向边缘，并且变形的膜通过差压保持张力。
