Abstract: 1. Method of evening out the steady-state running of a reciprocating internal combustion engine having three or more cylinders, wherein the mean indicated pressure of at least one cylinder is varied, characterised in that at least one order of the torsional vibrations of the drive system is minimized by : in a first step of the method : measuring the torsional vibrations at the drive shaft or at a shaft (12, 22) connected kinematically to the drive shaft, by means of a torsional vibration meter (3), in a second step of the method : subjecting the measured torsional vibrations to a Fourier analysis for torsional vibrations, in a third step of the method : determining correction factors for the variation of the mean indicated cylinder pressure of at least two cylinders in a computer from the ascertained amounts and phase positions of the torsional vibration amplitudes and from comparison of predetermined torsional vibrations produced by the individual cylinders (161, 162, 163, 164, 165, 166), in a fourth step of the method ; the correction factors effect a variation of the amount injected per injection step of the injection pump (61, 62, 63, 64, 65, 66) at least one of these two cylinders.

Abstract: A valve operating mechanism for an internal combustion engine having a valve (1) disposed in an intake port or an exhaust port of a combustion chamber and being openable by a rotatable cam (3, 4) and cam follower in synchronism with the engine crankshaft rotation. The valve (1) is normally urged toward the closed position by a spring means encircling the valve. Means (11) are provided for varying the resilient force urging the valve (1) toward the closed position during different engine operating conditions, such as, increasing the resilient valve closing force during high-speed operation for ensuring proper valve operation and descreasing the resilient valve closing force during low-speed operation for reducing friction in the valve operating mechanism. The valve operating mechanism preferably includes means for switching between actuation by a low-speed cam (3) or a high-speed cam (4). One form of the spring means includes a mechanism for increasing the spring force on the high-speed cam follower only during high-speed operation. Another form of the spring means includes a valve spring having a non-uniform rate of compression for imposing a higher rate of increase of spring force as the valve is opened a larger amount at high-speed.

Abstract: A spacer assembly for imparting a swirl to a passing steam water mixture within a fuel channel of a boiling water reactor is disclosed. The spacer assembly is placed at periodic intervals along the inside of a square cross sectioned fuel channel so as to separate the fuel containing rods from each other and the fuel channel sides. Each discrete spacer element is con­structed of a matrix of helically twisted sheet metal spacing elements (E1-E4) for the serendipitous purpose of pro­viding separation of the steam and water, with water being deposited on the fuel rods (R) surfaces. Each helical element is a twisted planar metallic member and includes a rotation of the metal surfaces in the order of 450° over a typical two inches of length. For each 90° interval of rotation from the top and bottom of each helical element, paired lattice connections are provided for attachment to adjoining elements. Intermediate of the lattice connectors at 45° for confrontation to the spaced apart fuel rods, there are placed rods stops. The resultant spacer thus improves the thermodynamics of steam generation by maintaining water on the fuel rods, imparts swirl to the steam water flow between spacers, and provides a lighter and less neutron absorbing metallic mass in the reactor.

Abstract: PFBC power plant for burning fuel, primarily coal, in a flu­idized bed of particulate material, at a pressure exceeding the atmospheric pressure. The plant comprises a bed vessel (12) which is divided into a first section (14) and a second section (16) by a vertical partition (17) which reaches up to the upper wall of the bed vessel (12) so as to form two separate freeboards (86 and 46, respectively), one for each section of the bed vessel. The first section (14) of the bed vessel (12) forms a gas generator in which a burnable gas is generated. This burnable gas is cleaned in a gas cleaner (90), then burnt in a secondary combustion chamber (98), and then mixed with the combustion gases from the second section (16) of the bed vessel (12), thus raising the temperature of the gas supplied to a gas turbine to an optimum level for the gas turbine.

Abstract: The invention relates to a method and an arrangement for detecting ionizing current in an ignition circuit (32, 33) incorporated in the ignition system of an internal combus­tion engine, in which a measuring voltage is applied to the ignition circuit (32, 33) in at least one secondary winding (30, 31), and in which a measuring device (29) is used to detect the possible presence of an ionizing current in the ignition circuit (32, 33). 
     A normal problem existing when measuring ionizing currents is that the spark plugs become coated with soot deposits, as a result of the electrical voltage field which always exists between the electrodes of respective plugs. This problem is particularly troublesome during an engine start sequence, since the deposits can prevent the engine from starting. The invention solves this problem, essentially by applying sole­ly a low measuring voltage during an engine start sequence, or alternatively no measuring voltage at all, and by apply­ing a high measuring voltage subsequent to the engine start.
