Abstract: A process of mechanical power generation including a binary cycle whose primary cycle works with a mixture of water and another substance of much lower volatility substantially immiscible with water. In the primary cycle, at least part of the vaporization of the water is accomplished by means of the heat yielded simultaneously by condensation at variable temperature of the substance of high boiling point. This binary cycle allows obtaining much higher efficiencies than conventional cycles in small power plants (up to 50 MWe), thanks to the diminishing energy losses in the heat absorption, optmising the expansion efficiencies with simple turbines and substantially eliminating the vacuum in the installation. The proposed cycle has better partial load efficiency and lower response time than conventional cycles, with similar cost.

Abstract: The present invention relates to a device for feeding out material from a low-pressure pocket 16 using a projection device 6 which travels to and fro. The present invention solves the problems which arise with the prior art in connection with the fetching motion of a projection device. The one of these problems is that the material column, in the case of certain fine-grained materials, is sucked into the low-pressure pocket 16, whereupon the material column will follow the projection device forward and back without any material leaving the low-pressure pocket 16. The other problem is that a minor quantity of material will always be transported by the projection device in the wrong direction, that is to say into the projection device housing. If this material is not regularly removed, it will provoke an operating stoppage. The present invention solves these problems by a discharge sleeve coupling in its front, upper part having been provided with a hinged, flexibly rigid return lock 4 and by a projection device housing having been provided with a chute 9, down which the material transported in the "wrong" direction has been fed, and with a spring- loaded cover plate 10, which covers the chute over the whole of its open surface in connection with the opening of dampers 13, the material which has been fed down the chute 9 being transported pneumatically back to the low- pressure pocket 16. <IMAGE>

Abstract: The invention relates to a novel type of support insulator which, because of its better resistance to impurities and precipitation, may be made considerably shorter than a conventional support insulator for the same voltage and which is able to withstand a considerably higher voltage at the same overall height, respectively. The support insulator (1) is intended to separate a first and a second electrode at different electric potential and has been given an outer pear-like shape. The insulator comprises a continuous supporting rod (8) of insulating material. The first electrode, which lies at high-voltage potential, is divided into a first (2) and a second (6) electrically conducting part, arranged around the rod (8) spaced somewhat from each other and electrically interconnected by means of a conductor (7). The second part (6) is thereby placed nearest the second electrode. These parts (2, 6) and the conductor (7) are enclosed by insulating material so that a first solid of revolution is formed around the first part and a cup-shaped second solid of revolution (4) is formed around the second part. The second solid of revolution (4) has been given a considerably larger diameter than the first solid of revolution (3). Further, it is suitable for the space (10) around the rod (8) between the cup-shaped solid of revolution and said second electrode to be enclosed by a shell of insulating material and for the space (10) to be filled with an insulating agent, for example SF6.

Abstract: The invention concerns a method of injecting primarily rock or concrete by pumping a sealing agent (19, 23) in pre-drilled holes (2, 3, 4, 32, 34) in the rock (1) or the concrete (33). The sealing agent (19, 23) is in liquid form and is pressed into fissures (5, 36) in the rock (1) or the concrete (33), sealing said fissures as it solidifies. While the sealing agent (19, 23) is still in liquid form inside the injection hole (2, 3, 4, 32, 34) it is made to flow out of the latter, while checked, to be re-used, in that another agent (19, 23) is pumped into the hole (2, 3, 4, 32, 34). A device for performing the method consists of a sleeve (6) applied in an injection hole (2, 3, 4, 32, 34) having an inlet/outlet (8) and a valve (9), and of a pipe (10) extending in a liquid-tight manner through the sleeve and into the hole (2, 3, 4, 32, 34), said pipe having an inlet/outlet (15) and a valve (14) positioned externally of the sleeve (6). A conduit (21, 25) leading from a supply (18, 22) containing a sealing agent (19, 23) is connectable to any one of these inlets/outlets (8, 15). A pump (20, 24) in the conduit (21, 25) is arranged to feed the sealing agent (19, 23) into the injection hole (2, 3, 4, 32, 34) to fill up fissures (5) in the rock (1) or the concrete (33).
