Abstract: A transmission chain comprising links and hinge pins extending through link apertures an intermediate member being received between each hinge pin and the opposite aperture sides of a plurality of adjacent links, the length of the intermediate member being equal to or somewhat less than the length of the hinge pin a limited displacement thereof in the longitudinal direction being possible.

Abstract: Clamping device having clamping members cooperating via a pressure area and an intermediate member with a pressure member, the intermediate member consisting of a slide member having a cross section in the form of a segment of a circle, a plane surface cooperating with the pressure area and a circular arc-shaped surface in a corresponding seating provided in the associated clamping or pressure member.

Abstract: The disclosure concerns a transmission chain. The chain may be used in a transmission with conical disks (not shown). The chain comprises a number of links intercoupled by hinge pins extending through openings in the links. The interacting surfaces of each link are, on the one hand, one of the sides of each of the openings of the links coupled by a hinge pin and, on the other hand, one of the opposite curved side surfaces of a single hinge pin.

Abstract: A vessel comprising a pair of laterally spaced elongated buoyancy hulls and vertically mounted thereon a plurality of hollow columns, distributed around the outer circumferential area of the vessel and supporting a work platform above the water level when the hulls are submerged, the hulls containing water ballast compartments. The platform supports one or more heavy duty cranes, adapted for outboard handling of loads. At the lower end of the columns, air chambers are provided in open connection with the surrounding water at their bottom ends. At their upper ends these chambers have air valves for discharging air from and supplying air to the chambers selectively controlled by directions from a computer which is added to the crane operating device.

Abstract: A wheel-bogie for supporting a crane, said bogie comprising a load-carrying foot, a main frame, at least two intermediate frames and a number of wheel frames; the transfer of the load from the foot to the main frame and from said frame to the intermediate frames and then to the wheel frames is effected by means of line contact occuring between two cooperating cylindrical planes with different radii of curvature.

Abstract: A pull strand of high tensile strength which may be composed of a number of parallel, longitudinal steel wires and a series of transverse, stiffener elements made of aluminum or other metal spaced along the pull strand and providing oppositely facing lateral edges for active engagement with coned sheaves are interconnected solely by a continuous molded body of rubber or rubberoid material in adherence with the pull strand and with the transverse elements. The molded body runs longitudinally through identical cavities of the said transverse elements, extending sidewardly at least onto their lateral edges and filling intermediately thereto at least a portion of each space between the sidewalls of the said transverse elements along the said cavities.

Abstract: A stabilizing system for a crane vessel of the twin hull semi-submersible type having a working platform supported above sea level by columns on submersible hulls. Water ballast compartments above sea level on the corner columns are discharged selectively in order to stabilize the vessel during handling of heavy outboard loads by cranes. The water is discharged through controlled valves of special construction. This control is regulated in dependence of measured values of the moment of force applied on the vessel by the crane load, and effects the operation with the help of a computer.Lower water ballast compartments in the columns have an additional "passive" function and the water can be discharged therefrom by pressurized air or by pumping it into the upper ballast compartments.

Abstract: The trapezoidal cross-section or profile of an endless driving belt is shaped by means of an uninterrupted row of thin metal plates transversely mounted on a metallic pull band over the entire length thereof. The plates are pressed against each other by tensile stress in the pull band. The pull band may advantageously be subdivided into two separate, parallel band strips each these two strips being inserted from oppisite sides in sideward slots provided in the metal plates. The alignment of each plate in a plane perpendicular to the longitudinal direction of the band is maintained by coupling means between all contiguous plates preventing lateral shifting of each plate with respect to its adjoining plates but allowing a slight mutual tipping of the plates around an axis perpendicular to the longitudinal direction of the pull band and parallel to the plane thereof.
