Overlapping wound vulcanized fabric strips with internally exposed or embedded spring steel support helix and additional external glass fiber cord fixation, for NEO 1/2 and SIL 1/2 hose types. Variable production possibilities of spiral hoses made of different materials, foil. We have proposed and implemented a scheme for Spiral Phase Plate (SPP) with continuous surface fabrication on fiber tips. By combining Focused Ion Beam-Scanning Electron Microscope (FIB-SEM) system and bitmap (BMP) format processing method, we fabricated a SPP with the topological charge of 1 on.

This paper presents a work for the development of a new fiber reinforced polymer (FRP) tube for seismic application. A proposed column consists of a FRP-Wrapped Spiral Corrugated Tube (FWSCT) filled with concrete. Five specimens were cyclically tested to investigate the flexural and shear strengths. The hose cover protects the hose against external influences such as abrasion, chemicals, electrical voltage, mechanical stress, ozone, UV rays and weathering. Spiral Fin coils are used for heating, cooling and dehumidifying.
