Abstract: A cable bolt for providing support and balance to a rock mass, comprising: a multi-strand cable having a plurality of steel wires being twisted together, said multi-strand cable having a first end portion for anchoring in a borehole of rock mass and a second end portion for being positioned adjacent to the opening of the borehole, a fixture secured to the second end portion of said multi-strand cable, wherein at least one of the plurality of steel wires is made from steel having as steel composition: a carbon content ranging from 0.20 weight percent to 0.95 weight percent, a silicon content ranging from 0.5 weight percent to 2.0 weight percent, a manganese content ranging from 0.40 weight percent to 1.0 weight percent, a chromium content ranging from 0.0 weight percent to 1.0 weight percent, a sulphur and phosphor content being limited to 0.

Abstract: An aquaculture net (1) comprises wires that form sidewalls (2) and a bottom (3) of the net (1). The sidewalls (2) form a perimeter for the aquaculture net (1). The aquaculture net (1) further comprises a frame (4) fitting inside the perimeter and leaving a gap between the frame (4) and the perimeter. The frame (4) has a removable auxiliary net (5) inside the frame. The frame (4) is movable up and down inside the perimeter. The frame (4) is provided with bristles or brushes (6) pointing outwards the frame and bridging the gap between the frame (4) and the perimeter.

Abstract: Aquaculture net (30) having a bottom net (31) and side walls (32), said bottom net (31) configured of four or more mesh parts (34) of a chain link fence, said chain link fence comprising a wire direction (33) and a flexible direction, wherein the wire direction of each mesh part (34) is perpendicular to the outer side (36) of said mesh part, said outer side corresponding to the circumference of said bottom net, and wherein the outer sides of said mesh parts are knotted. The invention also provides a method for manufacturing such an aquaculture net.

Abstract: An aquaculture net (20) has one or more side walls. These side walls comprise wires (12, 14) in a wavy form with maxima and minima, wherein the maxima of one wire (12) interlock with minima of a neighboring wire (14) to form patterns of a series of diamonds. The one or more of side walls have at least two parts (22, 24) wherein the wire direction in one (22) of said parts is different from the wire direction in another (24) of said parts. The aquaculture net (20) thus combines the advantages of a net with horizontal wires in the side walls with the advantages of a net with vertical wires in the side walls.
