Patent EP-0206517-A2 (EP)
Inventor: AMENT FRANK
IPC: F02D41/40
Filed: 1986-05-21
Abstract: IV The timing of the injection of fuel to the cylinders of a diesel engine (12) is normally determined in accordance timing values obtained from an empirically derived steady state timing schedule but is modified during transient operation of the diesel engine by an amount determined in accordance with the cylinder-to-cylinder change in requested fuel quantity. In light to moderate engine acceleration, the steady state timing value is modified by a correction amount which serves to retard the start of injection for effecting a reduction in engine noise and exhaust emissions. In periods of heavy engine acceleration, the steady state timing value is modified by a correction amount which serves to advance the start of injection to improve the engine performance. When the cylinder-to-cylinder change in requested fuel quantity indicates a return to substantially steady state operation, the correction amount is reduced in relation to the correction amount magnitude and the cylinder firing frequency.

Abstract: Air is mechanically entrained in an aqueous solution of surfactant and poly(oxyalkylene) polyisocyanate polymer, the poly(oxyalkylene) portion of which contains sufficient oxyethylene units to render the polymer water-soluble and hydrophilic, to form a fluid, water-based air foam which is sprayed or otherwise applied to exposed surface of a substrate, such as a body of hazardous material, the applied foam gelling or increasing in viscosity, due to reaction of the polyisocyanate polymer with water to form a poly(oxyalkylene) polyurea polymer, and forming a persistent gelled air foam or viscous air foam in the form of a coating on the exposed surface, thus sealing or otherwise protecting or controlling the substrate.

Abstract: In a device for controlling the speed of a diesel engine as a function of an arbitrarily actuated mechanical operating element of an electrical reference element (2), an electronic regulator (4) actuated by the reference element is provided, the output of which is connected via an electromotive final control element (12) to an adjusting lever (17) which regulates the delivery of an injection pump (22). An electrical speed signal can be fed into the electronic regulator (4). The electronic regulator is fitted with a limit speed control function designed to limit the speed of the diesel engine. In addition a mechanical limit speed regulator (centrifugal governor 8) is coupled to the injection pump (22). The mechanical limit speed regulator is set to regulate the delivery for a safety limit speed (nsO) which is greater than the maximum speed (nvO) from which the electronic regulator begins to function. <IMAGE>

Abstract: In the hybrid coder for video signals described, the data of a video image are subdivided into equally large datablocks and each datablock newly input is compared with a datablock of the preceding video image by means of a subtracting unit (SR). The datablocks of the preceding video image are stored in an image store (BS). To keep the transmission bit rates as low as possible, the datablocks are usually subjected to a transformation (for example a Fourier transformation) (F) and a subsequent quantisation (Q). At the high bit rate reduction required, coarse quantisation is necessary, which results in high quantisation noise. To eliminate the quantisation noise, a block-by-block adaptive low-pass filtering (T,FT1) is carried out in two signal paths of the hybrid coder. The quantiser (Q) can then be scaled more finely or even omitted entirely. The consequence of the low-pass filtering (T,FT1) is an unsharp video image which, however, is free of the interference of the quantisation noise which distorts the image in sections. <IMAGE>

Abstract: A probe mount carries a probe with test points having ends in a test point plane. The probe mount is supported at three spaced apart locations by respective first, second and third supports, each adja­cent to a respective one of the test points. These probe supports permit independent shifting of each of the three locations along respective parallel lines. As these locations are shifted relative to one another, the test point plane is tilted until it is parallel to a second plane containing the surface of an integrated circuit wafer to be probed. A test sur­face is positioned in the second plane and advanced toward the probe. As the test points contact the test surface, the test point plane is tilted. Micro­processor controlled stepper motors may be used to tilt the test point plane and to shift the test surface.

Abstract: The interference of dehydroascorbic acid, an oxidation product of ascorbic acid, in analytical methods is reduced with the use of certain nitrogen-containing organic buffers. Dehydroascorbic acid tends to cause premature reduction of reducible compounds which are used to provide detectable species in the presence of an analyte. These organic buffers, as opposed to inorganic buffers, prevent premature reduction of the reducible compounds. An analytical method can be carried out in solution or in a dry analytical element.

Abstract: In processing high-alloy martensitic steels, cracks frequently already form due to brittle fracture phenomena, and these put further processing in question or make it even completely impossible. In some cases, such damage in highly stressed plant components may manifest itself only when under stress and cause unforeseeable failures. An investigation has shown that the occurrence of this type of damage does not depend on the chemical composition of the steel but on the type of machining and that the structural component responsible for this damage is  delta -ferrite which frequently forms during processing of the steel. It is the object of the invention to provide a process for producing semi-finished and finished products, which precludes the formation of delta -ferrite during the machining of the steel or by means of which the  delta -ferrite which may have formed during machining of the steel is dissolved again. The object is achieved when a) after cold-forming with a degree of cold-forming of more than about 20 % b) after conclusion of the forming process by hot- and/or cold-forming, an additional heat treatment termed stabilisation annealing is carried out before the heat treatment for hardening and tempering, in order to obtain a structure free of  delta -ferrite.
