Abstract: A method and apparatus are provided for detecting a fault condition on a power system. By rectifying power system phase voltages to produce a rectified waveform, and filtering the rectified waveform or a representation of the rectified waveform through a finite gain synchronous band pass filter to generate a synchronous band pass filter output waveform that indicates the magnitude of a predefined harmonic frequency component, a fault condition on a power system can be identified.

Abstract: Superior piston bowl and combustion chamber configurations are designed for a reverse tumble spark ignition direct injection engine. The piston includes a shallow bowl extending from adjacent an edge of the piston head to an inner side slightly beyond a peak. The bowl features a bowl lip re-entrant angle at the spark plug location having an open or positive re-entrant angle. On lateral edges of the bowl between the inner and outer edges, wing like extensions include negative re-entrant angles. These help contain the injected fuel within the bowl during combustion. Other features of the combustion chamber include vertical intake ports that produce a weak reverse tumbling air flow motion with a tumble ratio of about 0.6, which allows increased flow efficiency of the port. An injector spray cone angle of 90 degrees is preferred with a bowl sized to capture the spray. Various additional features are disclosed.

Abstract: The present invention provides a fuel injector mounted on a side of a combustion chamber and delivers an ovalized fuel spray toward an oblong piston bowl of the chamber. The ovality of the spray is selected in relation to the oblong piston bowl and the motion of the combustion chamber air charge during the piston compression stroke to maintain the fuel charge within the piston bowl volume (including the space above the bowl) during compression and combustion of the fuel charge in the chamber. The shape of the oval spray may be adjusted as desired. In a specific embodiment, the ovality of the fuel spray indicated by the ratio of the major dimension to the minor dimension is in the range of about 2/1 to 4/1 for delivery into an oblong piston bowl with an ovality of about 1.2/1 to 1.5/1.

Abstract: A system for cleaning clogged orifices of a fluid head includes both apparatus and method by which reverse flow of a cleaning solution is combined with providing the vibrational energy of an ultrasonic frequency generator to the fluid head. A liquid pump and a filter interconnect between the input terminal of a fluid head to be cleaned and the input to the cleaning chamber of the apparatus so that a liquid cleaning solution reverse flushes the clogged fluid head, while the ultrasonic frequency generator is providing vibrational energy to break loose stubborn clogs.

Abstract: The present invention concerns prodrugs whose aromatic oxidation, particularly their enzymatic aromatic hydroxylation, results in their activation by the release of a drug moiety. It particularly concerns anti-tumour prodrugs and those which are specifically activated by the hydroxylation activity of the P-450 enzyme CYP1B1.

Abstract: The magnetic sweeper of this invention includes a laterally elongated hollow body of non-magnetic material having an open top and containing a pair of laterally spaced permanent magnets. The elongated side walls of the body have outwardly extending flanges slidably receiving a pair of covers of non-magnetic material for the magnets, and the covers have outer downturned ends facing the closed end walls of the body. An opening in each downturned end removably receives a wheel axle having an enlarged end captured between the body end wall and the adjacent downturned end of the cover, and interengaging detents on the body and each cover secures the cover removably to the body. A wheel is mounted rotatably on each axle and a handle extends from the body member for manipulating the sweeper over a surface to be swept of metallic objects.

Abstract: A retaining cap for an arm of a differential frame in an interaxle differential assembly removably secures a pinion gear on the arm between a central hub of the frame and the retaining cap, without the cap being supported by a frame structure. The retaining cap has female threading which engages male threading on the distal portion of the arm. An effective amount of a thread locking compound is applied to the threading prior to engagement.

Abstract: A technique for chemically planarizing an exposed surface of metal on a substrate to a pre-determined thickness is provided. The substrate has an exposed metal surface such as copper circuitry on a dielectric substrate which is to be planarized. Typically, this will be circuitization extending above a photoresist layer. A planarizing head is rotated against the substrate, with the planarizing head in contact with the metal surface on the substrate. A chemical etchant, essentially free of abrasive material, is continuously supplied to the interface between the metal surface and the planarizing head. The planarizing continues until a predetermined thickness of the metal has been reached. In circuit board manufacturing, this will form a surface co-planar with the photoresist. In some instances where significant height reduction is required, thus requiring significant metal removal, several passes of the substrate may be required or a device with multiple heads may be used.
