The invention relates to a drive cable for actuating a vehicle member being movable as against a vehicle structure, comprising a cable body (26) which is made of plastics, and which includes an denticulation (28) extending in the axial direction for engaging with a driving toothed wheel (24) and through which an armouring extending in the axial direction reaches. The denticulation (28) is formed by pocket-like recesses (34) which are spaced apart in the axial direction at regular intervals, and which are limited, in the longitudinal direction of the cable, by flanks of resulting tips of teeth (36) formed by the cable body (26) and in the transverse direction of the cable, on each of their two sides, by a pocket flank (38) and which are in each instance limited by a root of a tooth (40) on the bottom side, the armouring reaching through said cable body (26) beneath said recesses (34) and said tips of teeth (36), the armouring defining an armouring plane (A) which extends in the transverse direction of the cable and in the longitudinal direction of the cable, and in which at least two continuous armouring harnesses (30A, 30B, 30C) extending in the axial direction are arranged side by side and/or in which at least one armouring harness (30) having a flat cross-section is arranged.


A masonry reinforced with at least one bed joint masonry reinforcement structure. The bed joint reinforcement structure includes at least two cords, which have metal filaments that are twisted together. The cords are oriented parallel or substantially parallel in the length direction of the masonry reinforcement structure.

The filter for gel shearing and particle filtration of molten polymer comprises a first layer of metal fibers of an average equivalent diameter between 8 and 65 m. The cross-section of the metal fibers has two neighboring straight sides with an included angle of less than 90 and one or more irregularly shaped curved sides. The metal fibers have an average length of at least 6 mm. The metal fibers are bonded to each other by means of metal bonds; wherein the metal of the metal fibers of the first layer is the bonding agent forming the metal bonds. The filter comprises a second layer of metal fibers. The average equivalent diameter of the metal fibers of the second layer is smaller than the average equivalent diameter of the metal fibers of the first layer.


Saw cords used for sawing natural or manmade stony materials are made of saw beads threaded on a steel cord (52,522,522), wherein the saw beads are separated by polymer spacers. The saw beads comprise a metal sleeve (204, 304) of which the outer surface is covered with an abrasive layer. The inventors observed that saw cords returning from the field frequently failed due to saw beads that begin to rotate during use thereby eroding away the polymer between the steel cord and the inner of the saw bead. Eventually, the polymer is worn away and the outer steel filaments of the steel cord are ground away due to the interaction with saw dust and water. The inventors provide the inner surface of the sleeve with two sets (214) of parallel grooves in a first (206, 306) and second (208,308) axial part of the sleeve. The two sets of parallel grooves differ in at least one of the groove angle (,), the groove offset () or the groove spacing (1l, D2), thereby preventing axial movement of the sleeve and blocking the rotation of the saw bead.

An apparatus (100, 200, 300) and a method for measuring residual torsions of an elongated structure (202) such as a steel cord use a pivot head (102). The pivot head (102) comprises a wheel (104) adapted to guide an elongated structure (202). The wheel (104) is mounted in the pivot head (102) to transmit torques exercised by the elongated structure (202) on the wheel (104) to the pivot head (102). The pivot head (102) is mounted along a pivotal axis (110). This pivotal axis (110) lies in a plane of the wheel (104) and comprises the centre of the wheel (104). Sensor means (116, 206) measure the torque on the pivot head (102). The pivotal movement of the pivot head (102) around the pivotal axis (110) is limited to an angle range of 5, preferably 3 in order to reach an improved accuracy of the torque measurement.

A protective fence for rock fall protection structures or to stabilise a layer of earth, comprising a plurality of elongated steel elements being interconnected in form of meshes,wherein at least one of the plurality of elongated steel elements 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 per cent to 1.0 weight percent,a sulphur and phosphor content being limited to 0.025 weight percent, the remainder being iron,and said steel has as metallurgical structure:a volume percentage of retained austenite ranging from 4 percent to 25 percent, the remainder being tempered primary martensite and untempered secondary martensite.


The invention relates to a masonry reinforcement structure (100) comprising at least two assemblies (102) of grouped metal filaments, at least one positioning element (104) for positioning the assemblies (102) of grouped metal filaments in a predetermined position and a polymer coating (110) for securing the assemblies (102) of grouped metal filaments in this predetermined position. The invention also relates to a method of manufacturing such masonry reinforcement structure (100) and to a roll comprising such a masonry reinforcement structure(100). The invention further relates to masonry reinforced with such masonry reinforcement structure (100) and to a method to apply such masonry reinforcement structure(100).
