Abrégé

An arrangement for synchronization between at least two data acquisition devices of an online monitoring system for monitoring an electrical distribution network, each located at a known point A or B in the network and configured to detect high-frequency events during data acquisition phases. During a first phase of estimating the period of the electrical signal travelling through the network, each data acquisition device samples the electrical signal travelling through the network and deduces therefrom an estimate T′A or T′B of the period of the electrical signal by detecting times of zero crossings of the sampled signal, which are locally timestamped by a timestamping means associated with each data acquisition device. One of the devices then sends an information signal at a first time of detection tZCA1,1, which is locally timestamped, of a new zero crossing of the sampled signal, and triggers a data acquisition phase at a first time TRA separated from the first time of detection by a duration corresponding to the first estimate T′A of the period of the electrical signal. The time of reception of this signal at the other device is also timestamped by a local timestamping means. After a duration corresponding to half the second estimate T′B of the period of the electrical signal following the time of reception has elapsed, this other device triggers a phase of acquiring high-frequency events over a plurality of successive cycles having a predefined cycle duration, at a second triggering time tRB determined locally and corresponding to a second time of detection of a new zero crossing of the locally sampled signal. It is then possible to determine a synchronization difference Δtoa between two high-frequency events acquired, over a given cycle, by the two data acquisition devices by calculating the difference between the second triggering time tRB and the first triggering time tRA.

A clamp (10) for holding a flexible slender structure includes a housing (11) with a through hole (12), where the through hole has a tapered section, and a gripping element (13) arranged in the tapered section of the through hole. The gripping element is movable in the axial direction of the through hole, and the gripping element has an outer surface facing the walls of the through hole and an inner surface (18) configured to grip the flexible slender structure. A movement of the gripping element in the axial direction in the through hole causes a radial movement of at least a part of the gripping element thus providing a gripping force on a flexible slender structure arranged in the clamp.

A transfer device for transferring flowable material between a first reservoir and a second reservoir is provided having a loading device (106) mounted on a support structure (101). The loading device (106) includes several loading arm sections (103-105) mechanically connected by pivot joints (113,116,118). The transfer device further has a transfer line (122) connecting the first and second reservoir. The transfer line (122) is composed of rigid and flexible transfer line sections (123-126, 133). The flexible transfer line sections connect the rigid transfer line sections. At an upstream end at least one rigid transfer line section branches into several flexible transfer lines, which are fluidly merged into the next rigid transfer line in flow direction.

A spacer device (20) for holding a cable (22) in a central region of a hollow longitudinal structure has, in one arrangement, a spacer body (21) with a through hole (23). The distance from the through hole to the outer surface of the spacer body varies along the axial direction of the through hole. The spacer body has a region with a maximum diameter. The maximum diameter functions as a pivot point/region for the spacer device in the hollow longitudinal structure, around which the spacer device can rotate when there is relative movement between the hollow longitudinal structure and the cable. The region with maximum diameter can have a curved outer surface to facilitate the rotation and reduce wear on both the spacer device and the inner walls of the hollow longitudinal structure.
