Abstract: A connecting rod for a piston engine, in particular a twin crankshaft piston engine, with a first connecting rod head (2) that comprises a first connecting rod eye (20) for mounting a connecting rod (1) to a piston (52) of the piston engine. A second connecting rod head (3) has a second connecting rod eye (30) for mounting the connecting rod (1) to the crankpin (58; 59) of a crankshaft (60; 61) of the piston engine, along with a connecting rod shank (4) that links the first connecting rod head (2) and the second connecting rod head (3). The connecting rod shank (4) has a narrow first connecting rod shank section (40) adjacent to the first connecting rod head (4) and the connecting rod shank (4) includes a wider second connecting rod shank section (45) adjacent to the second connecting rod head (3).

Abstract: A reciprocating piston combustion engine with at least one cylinder (2) in which a piston (1) is located, so it can be moved in a reciprocating manner; a first crankshaft (4); a second crankshaft (6); wherein the first crankshaft (4) and the second crankshaft (6) extend parallel to each other and rotate synchronously in opposite directions; wherein the rotation axes (X, X?) of the two crankshafts (4, 6) extend parallel to a common cylinder midplane (Z) and laterally offset relative to it; wherein a first piston rod and second piston rod (3, 5) are arranged at the reciprocating piston (1), so that the first piston rod (3) is pivotably connected to the to the reciprocating piston (1) with its first end and rotatably connected to a crankpin (40) of the first crankshaft (4), and that the second piston rod (5) is pivotably connected with its first end to the reciprocating piston (1), and rotatably connected to the crankpin (60) of the second crankshaft (6) with its second end, and wherein the crankshafts (4, 6) ar

Abstract: A piston engine which has at least one dry-running piston-cylinder unit. It has a first housing (1), at least one cylinder arranged in or on the first housing (1) in which a piston is reciprocably arranged. The piston-cylinder unit further has a first crankshaft (4) and a second crankshaft (5), the first and second crankshafts (4, 5) being arranged parallel to each other and synchronously rotating in opposite directions. The axes of rotation (X, X?) of the crankshafts (4, 5) are arranged parallel to a center plane (Z) of the cylinder, and they are laterally offset relative thereto. First and second piston rods (6, 7) are pivotally connected to piston (3). The first piston rod (6) has a first end pivotally connected to piston (3) and a second end connected to a crank pin (40) of the first crankshaft (4). The second piston rod (7) has a first end that is pivotally connected to piston (3) and a second end that is pivotally connected to a crank pin (50) of the second crankshaft (5).

Abstract: The present invention relates to an electrical connector designed for use inside a tube such as an ejector tube for the expulsion of bodies from the tube, whereby the electrical connector is ejected from the tube together with the respective body, such as a mine. As soon as the body leaves the tube, the connector automatically separates itself from the ejected body and falls apart. For this purpose the components of the electrical connector are so shaped that they cooperate for making electrical contact only inside the tube.

Abstract: A method and apparatus for detecting the leakage of coolant into the jacket of a nuclear reactor fuel rod. The apparatus includes a coolant absorbing means mounted at a predetermined location within the jacket. Upon leakage of coolant and absorption thereof pressure forces developed by the absorbing means locally deform the jacket. Periodic inspection of the jacket's exterior by gauges, optical instruments or the like, reveals the presence of such deformation thereby indicating the presence of coolant leakage.
