Title: Method and apparatus for controlling differentially driven wheel slip for an articulated vehicle
Inventor: HOSSEINI JAVAD
IPC: B60T8/175
Filed: 1992-09-18
Abstract: An anti-spin apparatus (100) for a vehicle is disclosed. The vehicle is articulated and has at least one axle set (118) with at least two driven wheels (101, 103). The anti-spin apparatus (100) includes braking mechanisms (131, 133) which controllably apply braking forces to each of the driven wheels. A controller (160) produces a slip signal having a value responsive to the difference in rotational velocity between the wheels (101, 103) of the axle set (118). A transducer (165) produces an articulation signal having a value responsive to the angle of articulation of the vehicle. Further, a microprocessor (205) receives the slip signal and the articulation signal, controllably modifies the slip signal in response to the value of the articulation signal. The microprocessor (205) then compares the modified slip signal with a first predetermined reference value, and produces a braking control signal in response to the modified slip signal value exceeding the first predetermined reference value. Finally, one of the braking mechanisms (131, 133) receives the braking control signal and controllably applies the braking forces to the faster rotating wheel (101, 103) in response to the received signal.

Inventor: RUVANG JOHN A
IPC: E02F9/28
Filed: 1994-03-08
Abstract: An elongated resilient wedge and spool retaining structure longitudinally extends through generally aligned openings formed in a replaceable excavating tooth point, and an adapter nose portion received in a tapered socket within the tooth point, to captively hold the tooth point in place on the adapter nose. The retaining structure includes a tapered spool member having an enlarged side portion received in the tooth socket and blocking removal of the spool member, and a tapered wedge member driven into the tooth and adapter openings to a position in which longitudinally extending series of ratchet teeth on facing sides of the spool and wedge members are intermeshed and releasably lock the structure in place within the tooth and adapter assembly. A recess formed in a nontoothed side of the wedge member receives a locking member that forcibly bears against a surface portion of the adapter nose opening and is movable into the recess in a manner compressing a plurality of elastomeric members therein. The elastomeric members are maintained in compression and exert resilient reactive forces that simultaneously act to draw the adapter nose into the tooth socket and forcibly hold the spool and wedge member ratchet teeth in intermeshed engagement with one another. A removal tool may be driven into a longitudinal passage extending through the retaining structure, centrally through the intermeshed series of ratchet teeth, to laterally separate the wedge member from the spool member and thereby facilitate the removal of the installed wedge member.

Title: Gasphase ion source for time-of-flight mass-spectrometers with high mass resolution and large mass range
Inventor: BERGMANN THORALD
IPC: H01J49/40
Filed: 1994-06-30
Abstract: Abstract To achieve a high mass resolution in a time-of-flight mass-spectrometerwith gasphase ion source, the initial velocity components in the direction of acceleration of the ion source must be kept small. This can be done by injecting the analyte gas or ion beam at right angles to the direction of acceleration into the ion source.   When the direction of acceleration and the direction of the analyte gas or ion beam or not colinear, the amount of unwanted gas ballast in the drift space of the time-of-flight mass-spectrometer will be less. This will increase the dynamic range of the mass-spectrometer. The heavier an ion is, the more its path will deviate from the axis of the ion source and if it deviates too far from the axis of the ion source it will be lost. This effect gives the limit of the mass range of such an ion source. If the electrical deflection field for these ions is already within the acceleration region of the ion source, its mass range can significantly be enlarged.

Title: Misfire detection method for an internal combustion engine
Inventor: NOBLE GARDINER A
IPC: F02P3/02
Filed: 1994-11-01
Abstract: A method for detecting misfire in the combustion cylinder of a spark ignition internal combustion engine. The method includes the steps of charging an ignition transformer to a maximum ignition charge and initiating an ignition discharge between electrodes of the spark plug. The ignition transformer is then charged to a predetermined diagnostic charge which is less than said maximum ignition charge. If combustion is occurring within the cylinder, the temperature and pressure near the spark plug will be sufficient to allow the diagnostic charge to discharge. If the diagnostic charge does not discharge, the charge will be reflected back into the ignition transformer where it will be detected by a circuit as an indicia of misfire.
