Abstract: There is illustrated and described a plastics material hose comprising: a hose wall of plastics material, and an electrical conductor, wherein the electrical conductor is constructed as a braid having a plurality of fibers. In order to achieve compensation for and reliable discharge of electrical charge concentrations with specific disadvantages being avoided, it is proposed that the braid have at least one carbon fiber.
Abstract: A device for distributing gases in liquids, comprising: an aerating element made out of plastic, with an upper side and a lower side joined with the upper side, a support element, and a gas inlet, wherein the aerating element comprises at least one cavity that can be filled with gas through the gas inlet, wherein at least the area of the upper side of the aerating element comprises holes, perforations or the like as the gas outlet, and wherein the support element is situated in the cavity of the aerating element. In order to enable a uniform and reliable aeration of larger water surfaces in a cost-effective manner, it is proposed that the width of the support element be greater than its height.
