Inventor: KRETSCHMAR KLAUS
IPC: C10M175/00
Filed: 1988-10-21
Abstract: In the process for the hydroconversion of heavy and residual oils, spent and waste oils mixed with sewage sludges in a typical liquid-phase hydrogenation with hydrogen-containing gases with addition of a finely ground material, this additive preferably has a large internal surface area. 
<??>Industrial and also municipal sewage sludges frequently contain problematic constituents which preclude disposal by application to fields in agriculture or landfill or by combustion and pyrolysis processes. 
<??>The additive is added in two different grain size ranges, in such a way that a part of the additive is a fine-grained fraction having a grain size of 90  mu m or less and another part is a coarse-grain fraction of a grain size from 100  mu m to 2000  mu m, preferably 100 to 1000  mu m, and that the process is carried out at a weight ratio of the feed oils and the sewage sludges used of 10 : 1 to 1 : 1.5. 
<??>The process is used for converting the vacuum residue from a Venezuelan heavy oil with addition of 2% by weight of lignite coke as an additive and admixing of 10% by weight of sewage sludge in a liquid-phase hydrogenation to obtain, in particular, useful liquid products and extensive conversion of the organic fractions of the sewage sludge.

Abstract: An engine control system derives a basic fuel supply amount on the basis of preselected parameters including an intake air volume associated value and modifies the derived basic fuel supply amount in such a manner that the modified fuel supply amount becomes equal to the basic fuel supply amount derived on the basis of the preselected parameters when the engine is not in an acceleration state satisfying a predetermined first condition, and the modified fuel supply amount varies at a greater rate than variation rate of the basic fuel supply amount derived on the basis of the preselected parameters when the engine is in the accelerating state satisfying the predetermined first condition. The basic fuel supply amount as modified may be further modified with a correction value during the engine accelerating state satisfying a predetermined second condition. The engine control system may further perform a spark ignition timing control system in which the spark ignition timing is determined with taking the modified fuel supply amount as an engine load representative data.

Abstract: An image of an original is recorded on a recording medium such as a film based on image signals produced from the original by scanning the original at a predetermined sampling pitch in a main scanning direction and also scan­ning the original in an auxiliary scanning direction trans­verse to said main scanning direction. Image image information is read from the original at a sampling pitch which is N times (N is a positive integer) larger than the predetermined pitch in the main scanning direction, and image information is read from the original on at least every Nth scanning line across the auxiliary scanning direction, to produce image signals. The image signals are then processed in an image processing mode for sharpness emphasis, for example. The processed image signals are extracted repeatedly N times and recorded on the recording medium in a main scanning direction thereof. Processed image signals on N scanning lines are also extracted which include at least the processed image signals corresponding to an Nth scanning line, and recorded on the recording medium in an auxiliary scanning direction thereof.

Abstract: A voltage is electrostatically induced at a sensing device (ED) in correspondence with a surface potential of a measured object (O). In the case where the sensing device uses a field effect transistor (DF) in transferring detected information, there are some factors decreasing the accuracy of detection. Various new arrangements prevent such decreases in the accuracy of detection. In the case of the surface potential of the measured object corresponds to an optical image, new arrangements ensure accurate detection of the optical image. In some cases, color component signals are obtained on the basis of a detection signal.

Abstract: Electromagnets (54) and spring-damper units (34) respectively impart forward movement and rearward movement to slider members (26, 26') having hammer faces (30) at their forward ends and armatures (32) intermediate their lengths. The electromagnets (54) and spring-damper (34) units are mounted by the frame of the print mechanism for independent longitudinal adjustive movement. Adjustive movement of the spring-damper assemblies (34) effects lateral alignment of the hammer faces (30) at the forward ends of the sliders (26, 26'). Adjustive movement of the electromagnets (54) effects adjustment of the forward movement characteristics of the sliders (26, 26'). Clamping forces are preferably imposed upon the electromagnets (54) pending and during their adjustive movement. Anchoring of the electromagnets (54) in their final positions preferably is accomplished by laser welding. An inexpensive frame plate (14) restrains lateral movement of the sliders, maintains desired spacing between the pole faces (62) of confronting electromagnets (54), and provides a surface upon which adjustive movement of the electromagnets can readily occur.
