Abstract: The invention concerns a life-saving vehicle (10) designed as a hollow body with the form of a sphere or disk essentially flattened along a vertical axis (16) that demonstrates its greatest width in a horizontal plane (15) and which body, composed of an upper part (11) and a lower part (13), limits an internal passenger compartment (25), whereby the body comprises a stabilizing arrangement (12) that stabilizes the vehicle when it is in water, a telescopic arrangement (40), a stabilization means (14) arranged at the lower part, which stabilization means can be displaced in a vertical direction downwards from the lower part through activation of the telescopic arrangement (40). The vehicle, in order for it to travel not only in the air but also in water, comprises: a first and second rotor (52, 17), a motor (55) with an associated transmission (54), a pair of propulsion units (60) and a stabilizing fin (65).

Abstract: For an apparatus and method to shut down pipelines, an apparatus frame is supported by the pipe to be shut down, and includes a pointed drill and a drill cylinder to drill a hole, essentially similar in diameter size with the plug cylinder or, when in the same temperature, essentially smaller in diameter size than the plug cylinder, through the pipe to be shut down. The apparatus includes a plug cylinder and equipment for installing the plug cylinder in the drill hole. There is a channel inside the drill cylinder and/or plug cylinder and/or shaft to feed a coolant, a flowing substance, preferably hydrogen, carbonic acid, or other such substance, cooling and at the same time reducing the size of the plug cylinder until it is inserted in the drilled hole. After the plug cylinder has been inserted, the flow of the coolant stops. As a result, the temperature of the plug cylinder increases, and the size of the plug cylinder increases as well.

Abstract: An apparatus for land, sea, and air defense, including a cylinder setup opening into a cylinder mast formed by nested cylinders and equipped with a weapon container. The weapon container includes, depending on the intended use, various weapons that fire automatically as well as ammunition. A drill, with a power device, is connected to the opposite end of the cylinder setup and cylinder mast's weapon container for drilling a hole into the earth.

Abstract: A safety valve to stop flow in the flow pipe (3), the safety valve including a drilling device (8) with its frame (6) to drill a hole in the flow pipe, a winding device (7) fixed to the frame of the drilling device and a band (4) wound with a winding device. The safety valve includes a sleeve to which sleeve a drilling device (8) and a winding device (7) have been fixed and the sleeve has been equipped with systems to fix it to the outside surface of the pipe (3).

Abstract: A system for detecting and positioning objects, the electric conductivity of which differs from the surrounding medium thereof by measuring variations in an electric field generated into the medium. More precisely, the invention concerns a method and assembly for detecting objects or objectives, for example vessels, in electrically conductive medium, for example sea, by measuring changes, disturbances, signs, indications or the like caused by the object or objective, especially for surveying water fairways and/or extent.

Abstract: A method and apparatus for accomplishing an underwater weld joint with a welding electrode between a support and an element to be welded fast onto the support in which the element to be welded fast is insulated from the ambient water with a protection cover which is disposed tightly against the free surface of the element to be welded fast and through the wall of which cover the welding electrode rotating about its longitudinal axis extends is led during the welding operation against the edges of an opening in the element to be welded fast, towards the support.

Abstract: A method and a tool for freeing of parts held fast, especially for freeing of bolts and nuts rusted fast under water. According to the invention an electric arc is created between the rotating endpiece (21) of the tool and the fast held part (1), with which the fast held part is heated and/or thermally cut, after which the fast held part can be freed from the fastened object.

Abstract: Disclosed is an improved method for arc cutting of metal, more specifically a method in which an electric arc is formed between the metal and a cutting torch and gas is blown into the cut during the cutting process. According to the invention a paste is injected through the torch into the region of the arc, said paste containing a finely-divided electrically conducting substance mixed with a carrier and acting as an electrode which causes the electric arc to be struck. The conducting substance may contain e.g. metal powder, such as powder of aluminium or of an aluminium alloy, to which also carbon and phosphorus may be added.

Abstract: A procedure is disclosed in the application, for carrying out arc welding under water or in otherwise difficult external conditions. In the procedure, there is introduced in the arc area or in its immediate vicinity, an auxiliary substance having the purpose to boost the ignition of the arc and its burning and to retard the cooling of the weld bead produced, so that the emergence of gases from the welded seam is promoted and the quality of the weld seam improves. The auxiliary substance used consists mainly of soap which is a salt formed by anions of a fatty acid, a fatty acid mixture or a mixture of fatty and resin acids and by metal cations or a mixture of such salts and which may in addition contain water and inorganic salts. Best results have been obtained by using for auxiliary substance soft soaps made of tall oil and which contain salts of both fatty acids, such as oleic and linoleic acid and of resin acids, such as abietic acid.
