Abstract: The present invention relates to a method for preparing polymeric films, preferably electroactive films, with enhanced physical properties by the steps of applying to a substrate a solution of a polymer containing pendant labile solubilizing groups, then removing the solvent and a sufficient concentration of the labile solubilizing groups render the polymer less soluble in the solvent than before the labile groups were removed. It is believed that the removal of pendant soluble groups a) permits optimization of the semiconducting backbone for charge transport performance, b) allows direct control of microstructure in the final film, and c) renders the final film more robust during subsequent process steps needed to construct multilayer devices.

Abstract: Invention relates to an on-board electrical generator system that may be retrofitted to existing railroad vehicles, such as freight cars, box cars, and the like, where rotation of the vehicle's axle powers the system. A preferred use thereof is to charge the battery for the electrically controlled brakes on the vehicle. Such vehicles typically include a chassis, having plural axles mounted thereon, and a journal box or adaptor block having a projection generally aligned parallel with the axles. Each axle contains a pair of wheels, which are inwardly mounted from the respective axle ends and rotatable with the axle. The generator includes a rotor fixed for rotative movement relative to a stationary stator, whereby such relative movement causes electric currents to be generated in the stator containing the generator in a non-rotatable housing.

Abstract: A dispensing head having a plurality of prong-like nozzles is useful for impregnating meat with tenderizing and flavoring liquids. It may be fitted onto a pressure dispenser of the conventional type containing a bag to hold the liquid, a gas pressure space thereabout, and a reciprocable dispensing valve. The head so utilized has an inlet leading to a flushable chamber communicating to several prong-liked nozzles which project on parallel axes from a meat pressing surface, preferably having a rim. Pressing this surface so spreads the meat against the sides of the nozzles as to seal them against the escape of liquid dispensed under superatmospheric pressure, thus forcing it to impregnate the meat. The dispensing head is readily flushed; and provisions are made for re-mounting on the valve stem without discharging the contents of the container.

Abstract: Apparatus for inserting wires into terminals comprises a templet plate having wire-receiving slots extending therethrough from one surface to the opposite surface.

Inserters move through the slots and insert the wires into a connector positioned under the other face of the templet. In accordance with a further aspect of the disclosure, a shuttle type wire feed is provided in combination with the templet plate and a second wire insertion apparatus is provided to produce electrical harnesses.
