摘要:
A transmission for a race car or other high performance vehicle includes a top mounted shift lever which has a remote location displaced rearwardly from the standard position directly above the gearbox. The shift lever can be mounted to either side of the gearbox to provide sufficient room and allowing the driver to be stationed away from the door for enhanced safety at the right side mounting position. A novel interlock mechanism is located in the transmission between the shift forks to provide a more compact arrangement and improved reliability.

The present invention relates to the field of motorized mobility devices for wheelchair users, specifically, portable collapsible motorized mobility devices for wheelchair users that removably engage the frame of a traditional wheelchair allowing for the wheelchair user to have a greater degree of autonomy and to negotiate a variety of terrains otherwise inaccessible to them. The present invention includes a collapsible platform operatively connected to a plurality of motorized rolling tracks and a plurality of securing means to secure the user's traditional wheelchair to the device to allow the wheelchair user a greater degree of autonomy.

摘要:
Bis-diazo,triaryl and aryldiazo-N-arylphenazonium quencher moieties, substituted with electron-withdrawing and electron-donating substituents which induce polarity in the delocalized aryl/diazo ring systems, are useful as labels when attached to biomolecules such as polynucleotides, nucleosides, nucleotides, and polypeptides. The quencher moieties are non-fluorescent and accept energy from fluorescent reporter labels by any energy-transfer mechanism, such as FRET. Fluorescence quencher compositions are useful in preparing quencher labelled biomolecules for various molecular biology assays based on fluorescence detection.
