Abstract: A fishing rod has a hollow interior in which is secured a semi-rigid line. The semi-rigid line is secured to a durable rubber band which in turn is secured to an interior base of the fishing rod, adjacent the handle. The opposite end of the semi-rigid line comprises a braided portion having a plastic anchor. A strike on the fishing line is thus transmitted through the fishing rod directly to the handle thereof.

Abstract: An aviation gasoline (Avgas) fuel composition possessing a high motor octane number and which contains reduced amounts of tetraethyl lead is disclosed. The Avegas composition preferably comprises about 20 to about 80 vol % iso-octane, about 5 to about 18 vol % toluene, about 1 to about 20 vol % C4 to C5 paraffins, about 0 to about 1 ml/gallon tetraethyl lead (TEL) and the balance light alkylate. The Avgas composition may be economically produced utilizing spare methyl tertiary butyl ether plant capacity to produce iso-octane as one component of the composition.

Abstract: A system employing thermographic techniques is provided for inspecting materials and detecting defects therein such as void, inclusions, interlaminar disbonds, or porosity. The system utilizes a composite material and a source of pulsed current which is delivered to conductive elements within the composite material which, in turn, heats the material being inspected allowing thermographic techniques to be employed to measure the temperature distributions related to the application of the heat source and indicative of the defects of the material being measured.

Abstract: Provided is a method for blending an unleaded summer gasoline containing ethanol. The method comprises providing a substantially oxygenate free unleaded gasoline blend stock having an RVP of no greater than 7.0, and preferably no greater than 6.0, and then adding sufficient ethanol to the gasoline blend stock such that the ethanol addition does not cause the T50 value to drop below the ASTM D 4814 minimum requirements of 170° F.

Abstract: Provided is an unleaded gasoline fuel which is substantially free of oxygenates, i.e., the fuel contains less than 1.0 weight percent oxygen based on the total weight of the fuel composition, and most preferably contains no oxygen containing compounds. The gasoline fuel of the present invention also has a Reid vapor pressure of less than 7.5 psi, a sulfur content of less than 30 ppmw, and more preferably less than 20 ppmw sulfur, and an aromatic hydrocarbon content greater than 30 volume percent and/or a 50% D-86 Distillation Point greater than 220° F. and/or a 90% D-86 Distillation Point greater than 330° F. The gasoline fuel preferably also has an olefin content of no greater than 8 volume percent, and more preferably 5 volume percent or less. It has been found that such a gasoline fuel offers a substantially oxygenate free gasoline which avoids the environmental impact of oxygenates, yet when combusted in an internal combustion automobile provides good performance and good emissions.

Abstract: A Josephson break junction device suitable for highly sensitive electronic detecting systems. A superconductor film such as YBa.sub.2 Al.sub.3 O.sub.7 is deposited on a substrate such as a single-crystal MgO. The film is fractured across a narrow strip by at least one indentation in the substrate juxtaposed from the strip to form a break junction. A transducer is affixed to the substrate for applying a bending movement to the substrate to regulate the distance across the gap formed at the fracture to produce a Josephson turned junction effect. Alternatively, or in addition to the transducer, a bridge of a nobel metal is applied across the gap to produce a weak-link junction.

The film is fractured across a narrow strip by at least one indentation in the substrate juxtaposed from the strip to form a break junction. A transducer is affixed to the substrate for applying a bending movement to the substrate to regulate the distance across the gap formed at the fracture to produce a Josephson turned junction effect.

Abstract: A series of pulses are transmitted to a first laser and the same series of ulses through a time delay network to a second laser. Each laser provides pulses of light through separate diagonal mirrors and through respective transparent holograms. Each light beam is then brought into convergence by respective sides of a wedge shaped reflector and brought into spacially coincident focus by an imaging lens onto the surface of a sample under test. The two hologram transparencies are imaged spacially coincident but separated in time on the face of the sample. Thermal elastic waves produced by laser heating at the sample surface transform into a desired acoustic beam pattern determined by the nature of the wavefronts which the hologram transparency represents. The position of the coincident image on the sample may be moved by varying the time between the two pulses.

Abstract: A transducer is provided having interconnections between a conductive member and one side of a heat sensitive piezoelectric substrate such as PVF.sub.2 to or from which electric signals flow. The interconnections are positioned on one side of the substrate with the opposite side having a metalization under the interconnection attachment positions and in a continuous region therebetween. The interconnection includes adhesive material such as epoxy disposed between and attaching an electrically conductive member to one side of the substrate and a single contiguous electrically conductive coating applied to adjacent portions of these two members to electrically connect them. Since both interconnections are positioned on one side of the substrate the transducer is adhesively fastenable to operational structure with a strong bond line, permits lead attachment after mounting and prevents lead shortout.

Abstract: Provided is an unleaded gasoline fuel which is substantially free of oxygenates, and most preferably contains substantially zero oxygenates. The gasoline fuel also has a Reid vapor pressure less then 7.5 psi, a sulfur content less than 30 ppmw, an aromatic hydrocarbon content between 25 and 30 volume percent, and/or a 50% D-86 Distillation Temperature between 210 and 220° F., and/or a 90% D-86 Distillation Temperature between 300 and 330° F., and the fuel composition fails the California Predictive Model requirements for emissions. Preferably, the olefin content of the fuel is also 8 volume percent or less. Such a gasoline fuel offers a substantially oxygenate free gasoline which avoids the environmental impact of oxygenates, yet when combusted in an internal combustion automobile provides good performance and good emissions, despite failing the California Predictive Model. The gasoline fuel in particular can provide surprisingly lower NOx emissions than that predicted by the California Predictive Model.
