Title: Cable Suspended Robot for Industrial Plants
Inventor: HASSANE TRIGUI
Filed: 2021-07-19
Abstract: Cable-driven robotic platform systems and methods of operation are disclosed. The system includes a robotic platform suspended by a system of overhead cables, motorized cable reels and pulleys. A master control computer coordinates operation of the motorized cable system as a function of sensor data captured by navigation sensors on-board the platform so as to move the robotic platform inside an industrial plant. The system is configured to maneuver around pipings and avoid obstacles in the plant in order to maximize the effective workspace that the robotic platform can reach to perform operations including inspection or repair. Additionally, a robotic “wire jacket” device can be attached to suspension cables and configured to crawl along a cable. The wire-jacket can be selectively positioned on a cable to provide an intermediate cable suspension point that improves platform mobility within congested spaces and avoids obstacles. Fig 1.

Abstract: An elastomer nanocomposite comprises an elastomer comprising a non-functionalized first elastomer and a functionalized second elastomer and a functionalized filler crosslinked with the elastomer, wherein the non-functionalized first elastomer and the functionalized second elastomer are independently an ethylene-propylene-diene monomer rubber; a nitrile butadiene rubber; a hydrogenated nitrile butadiene rubber; a butadiene rubber; a styrene-butadiene rubber; an acrylonitrile butadiene rubber; an acrylate-butadiene rubber; a natural rubber; a polyisoprene rubber; a polychloroprene rubber; an ethylene-vinyl acetate rubber; a polypropylene oxide rubber; a polypropylene sulfide rubber; a fluoroelastomer; a perfluoroelastomer; a polyurethane rubber, or a functionalized derivative thereof.

Abstract: Abstract Wire netting and method for manufacturing a helix for a wire netting 5 The invention is based on a wire netting (10a; 1ob), in particular a safety net, with a plurality of helices (12a, 14a; 12b) which are braided with each other, of which at least one helix (1 2a, 14a; 12b) is bent from at least one single wire, a wire bundle, a wire strand, a wire rope and/or another longitudinal element (1 6a; 16b) with at least one wire (18a; 18b), which in particular comprises a high-tensile steel, the at least 0 one helix (12a, 14a; 12b) having at least one first leg (20a; 20b), at least one second leg (22a; 22b) as well as at least one bending region (24a; 24b) connecting the first leg (20a; 20b) and the second leg (22a; 22b) to each other, It is proposed that the longitudinal element (16a; 16b is bent at least substantially torsion-free in itself along a contour of the first leg (20a; 20b) and/or of 5 the second leg (22a; 22b).
