Abstract: A low emission power generating apparatus which comprises a modified two-stroke diesel engine component (12) and modified turbocharger component (14) which has a relatively low aspect ratio. The diesel engine component (12) is a modification of a conventional two-stroke diesel engine design and includes an exhaust valve cam of unique design that has a cam profile which results in a later-than-normal exhaust valve (24) opening and an earlier-than-normal valve closing so that the time during which the exhaust valve (24) remains open is shorter than normal, thereby causing a substantially greater volume of residual gases to remain in the combustion chamber (18) following the scavenge stroke. Reduction in peak combustion temperature advantageously results in the lower than normal production of nitrogen oxide and, therefore, allows advancement of the injection timing, while still maintaining the NOx emissions coming form the engine lower than those legislatively mandated. The modified turbocharger component (14) provides an additional charge of oxygen-rich air into the combustion chamber (18).

Abstract: A diagnostic platform includes a processor, storage media and user interfaces, including a display screen, the processor being coupled to engine analyzer hardware and adapted to be coupled to a scanner for downloading data from vehicle on-board computers. The system stores libraries of information regarding vehicle identifications, drivability symptoms exhibited by vehicles, vehicle system and component tests and service codes which can be registered by the vehicle on-board computer. System software permits the user to input an identification of the vehicle under test and, in one mode of operation, displays a library of faults, such as symptoms or service codes, from which the user can select those exhibited by the vehicle, whereupon the system selects from the test library those tests pertinent to diagnosis of the causes of the selected faults and displays them in a hierarchically ranked order based on likelihood of successful diagnosis of the faults. The user can then select and initiate any displayed test. In other modes, the system initially displays one of the libraries of system or component tests, from which the user selects those deemed appropriate, whereupon the system highlights icons which can be selected for initiating pertinent test procedures. Selected test procedures may include links to the engine analyzer or scanner hardware or other appropriate test modules.

Abstract: An image is reproduced and transferred onto a substrate by (a) providing a positive electrode having a continuous passivated surface moving at substantially constant speed along a predetermined path, said passivated surface defining a positive electrode active surface; (b) forming on the positive electrode active surface a plurality of dots of colored, coagulated colloid representative of a desired image, by electrocoagulation of an electrolytically coagulable colloid present in an electrocoagulation printing ink containing a coloring agent; and (c) bringing a substrate into contact with the dots of colored, coagulated colloid to cause transfer of the colored, coagulated colloid from the positive electrode active surface onto the substrate and thereby imprint the substrate with the image. Step (b) is carried out by (i) providing a first and a second series of negative electrodes each having a surface covered with a passive oxide film, the negative electrodes of each series being electrically insulated from one another and arranged in rectilinear alignment so that the surfaces thereof define a plurality of corresponding negative electrode active surfaces disposed in a respective plane spaced from the positive electrode active surface by a respective constant predetermined gap, the first and second series of negative electrodes being arranged in spaced-apart parallel relationship with the negative electrodes of each series being spaced from one another by a distance at least equal to the respective electrode gap; (ii) coating the positive electrode active surface with an olefinic substance to form on the surface micro-droplets of olefinic substance; (iii) filling the electrode gaps with the electrocoagulation printing ink; (iv) electrically energizing selected ones of the negative electrodes of the first and second series in a controlled alternate manner such that the electrodes of the first series are energized prior to an undesirable formation of a gelatinous deposit on the electrode active surface of each energized electrode of the second series and the electrodes of the second series are energized prior to an undesirable formation of a further gelatinous deposit on the electrode active surface of each energized electrode of the first series, thereby causing point-by-point selective coagulation and adherence of the colloid onto the olefin-coated positive electrode active surface opposite the electrode active surfaces of the energized negative electrodes while the positive electrode active surface is moving; and (v) removing any remaining non-coagulated colloid from the positive electrode active surface.

Abstract: A structural system that may be applied as an element in the construction of buildings, portable shelters, furniture, home accessories or where rigid structural elements are necessary. The invention of this system is based on two principal parts, which, when combined produce a system with a load bearing capacity. A flat surface or sheet is pre-deformed or tensioned by a limiting membrane, forming a curvilinear volume. The structure is comprised of a bendable surface or a sheet and a tensile membrane connected along virtually the entire periphery of the sheet. The membrane can envelop the entire sheet so that the sheet is bent inside it. Because of the sheet, the stretched tensile membrane assumes a saddle-shape, or a surface of negative Gaussian curvature.

Abstract: The one-way hinge damper includes a cylindrical housing into a rotor is rotatably inserted. A gap is formed between the rotor and the cylindrical housing which is filled with silicone or a similar viscous fluid for damping the rotation of the rotor. The damping can be increased by forming longitudinal grooves or similar discontinuities in the interior surface of the cylindrical housing and longitudinal passageways on the exterior surface of the rotor.      A clutch, to which the output shaft is attached, is biased against an end of the rotor by a wave spring. Both the clutch and the end of the rotor include complementary rotationally alternating ramped surfaces and flat (or longitudinally level) surfaces. Radially extending walls are formed between the higher end of the ramped surfaces and the adjacent flat surface. When the output shaft and the clutch are rotated in a first direction, the radially extending walls of the clutch align with and engage the radially extending walls of the rotor and the rotor rotates through the viscous fluid thereby achieving damping. However, when the output shaft and clutch are rotated in a second direction, the ramped surfaces of the clutch "ramp over" the ramped surfaces of the rotor, and the rotor does not rotate, thereby allowing the clutch and output shaft to rotate substantially free of damping.

Title: Efficient implementation of typed view hierarchies for ordbms
Inventor: PIRAHESH MIR HAMID
IPC: G06F17/30
Filed: 2000-06-02
Granted: 2003-11-18
Abstract: A method for typed view hierarchies for an object-relational database management (ORDBMS). The views in the hierarchy are merged into a unified hierarchy view through case expressions for mapping and wrapping of overloaded columns. During the merge, the underlying logical tables are eliminated which results in a simplified query graph. The transformation is a non-loss operation which condenses the type information within the case expressions. This allows update, delete and insert operations to be resolved on the query graph on a local level. Using query rewrite rules, the case expressions may be simplified further.
