摘要： A plural screw machine has a housing (1) in which intermeshing helically profiled rotors (6, 7) define working chambers of volumes, and thus pressures, which vary as the rotors rotate. To prevent a build-up of heat in the rotors, a small flow of evaporable liquid such as water is directed at portions of the rotors subjects to higher pressures. The flow rate of the liquid is too small to effect any substantial cooling of the gas through the machine.
摘要翻译：多个螺旋机器具有壳体（1），其中啮合的螺旋形轮廓转子（6,7）限定了体积的工作室，并且因此限定了随转子旋转而变化的压力。为了防止转子中的热量积聚，小的可蒸发液体如水的流动被引导到转子的部分受到更高的压力。液体的流速太小，无法通过机器实质性地冷却气体。

摘要： A fluid having a positive-slope for a vapour part of its temperature-entropy diagram, such as n-pentane, is heated as a liquid under pressure in a heat exchanger (13) by heat from the source (12) and expanded to generate power in a two phase expander (17) to form a homogenous mixture of liquid and vapour which is delivered to a separator (20). The separated vapour is expanded in a turbine (25) to generate further power before being condensed in a condenser (28), the condensate being supplied to a first feed pump (41). The output of the pump (41) and the relatively small amount of liquid from the separator (20) are returned by a second feed pump (42) to the heat exchanger (13). In a modified arrangement, the liquid from the separator is returned by a further feed pump to an intermediate point of the heat exchanger.

摘要： A plural screw compressor-expander machine has a casing (10) in the interior of which are mounted intermeshing helical rotors (11 and 12). The rotors (11 and 12) are supported at each end in bearings in the end walls of the casing. The interior of the casing is divided by a transverse partition (14) into a relatively longer compressor portion (1) and a shorter expander portion (5). The higher pressure ports (16, 18) of the compressor and expander portions are adjacent the partition, on opposite sides of a plane through the rotor axes. Similarly, the lower pressure ports (15, 17) are on opposite sides of the plane through the rotor axes but adjacent the end walls. This arrangement reduces the loads on the bearings of the rotors.

摘要： A system for lifting and moving heavy loads, especially for use in the installation or removal of offshore platforms, comprising a number of lifting devices (1) which are arranged for mounting on a floating structure (2) which during use floats on the surface (3) of a volume of water (4) beside the load which has to be lifted. Each lifting device (1) comprises a lever arm unit (5) with a first (6) and a second (7) arm projecting in opposite directions from a common mounting point (8), the first arm having a lifting point (11) at its free end for engaging with the load, at least one first container (12) which is connected to the first arm (6) at a point near the said lifting point (11), and which is arranged to receive and discharge a flowable medium and to be submerged in the volume of water (4), and at least one second container (19) which is suspended at the free end of the second arm (7). The interiors of the containers are interconnected via a pipeline device (21), and a device (22) is provided for fast transfer of medium in the first container (12) via the pipeline device (21) to the second container (19).

摘要： A non-contacting grooved face seal assembly (10) for a shaft rotating at a high pressure and high speed with a combination of two groove patterns on one of the two sealing faces (17, 18; 118) of mating sealing rings (16, 18; 119); one pattern being relatively deep angled grooves (34; 134), and the other pattern being a relatively shallow annular groove (44; 144). The relatively deep groove pattern is optimized for hydrodynamic operation and on shaft rotation pumps the sealed fluid between the sealing faces to set the running clearance. The relatively shallow pattern is designed to hydrostatically prevent a friction lock of the sealing faces at starting and stopping of shaft rotation by admitting controlled amount of sealed fluid between the sealing faces (17, 18; 118) when the shaft is at or near to a stationary condition.

摘要： Helical intermeshing main and gate rotors (1, 2) are mounted for rotation about their axes in respective intersecting bores in a housing. The profiles of the rotors as seen in cross section are generated by the same rack formation. The high pressure flanks of the lobes of the main rotor (1) and of the grooves of the gate rotor (2) are both generated by a preferably cycloidal portion (GHA) of the rack R.
