Abstract: A method for ultrasonic living body tissue characterization using a transducer (3) and processor (9). The method includes the steps of transmitting an ultrasonic pulse into the tissue (4) and receiving a reflected pulse, calculating the normalised power frequency spectrum of the reflected pulse, determining the frequency at which the maximum value for the power spectrum occurs, determining the high and low half powerfrequencies, calculating the upper and lower frequency ratios of the maximum value frequency and the half power frequencies, and determining the power exponent of the frequency of the reflection coefficient. The frequency exponent of the reflection coefficient is used to calculatethe attenuation slope of the ultrasonic wave. The attenuation slope or the reflection power exponent is used to generate a tomographic image of the living tissue characteristics for visual non-invasive tissue diagnosis. The attenuation slope and/or the reflection power exponent tomographic image or the others can be combined with a reflection intensity tomographic image or the others to produce other diagnostic images.

Abstract: Fin structure for a heat exchanger is fabricated by folding a strip of material back over itself at locations along the length of the strip such that integrally joining one of the folds on opposite sides are first confronting portions each of which in turn integrally joins by a further fold with a corresponding second confronting portion of the strip. Each pair of first and second confronting portions are processed to form a fin which has an interior space by joining their margins. This joining extends from the fold which integrally joins the first and second confronting portions substantially to the one fold. The one fold is deformed by displacing material from it more fully between the two fins, and preferably this is done at both ends of the fold. The displaced material strengthens the structure and spaces the fins apart.

Abstract: A continuous process for thermally cracking a heavy hydrocarbon oil, including heat-treating the heavy hydrocarbon oil in a first thermal cracking zone for obtaining a first cracked product, and introducing the first cracked product into a second thermal cracking zone where it is thermally cracked by direct contact with a gaseous heat transfer medium to form distillable cracked components and a mesophase-containing pitch. The liquid phase in the second thermal cracking zone, including the mesophase-containing pitch, is withdrawn therefrom and separated into a mesophase-rich pitch and a matrix pitch having a low concentration of mesophase. The matrix pitch is recycled to the second thermal cracking zone. The dis-  t illable cracked components are stripped from the liquid phase in the second thermal cracking zone with the heat transfer medium, and the resulting gas phase is discharged overhead therefom and then separated into a light fraction and a heavy fraction. The heavy fraction is fed to a third thermal cracking zone to obtain light oil components and an aromatic tar. The aromatic tar is recycled to the second thermal cracking zone.

Abstract: A circuit is provided which is capable of band switching a voltage controlled oscillator (VCO) while maintaining the relative sensitivity of the voltage controlled device and, hence, the control line voltage itself. The circuit includes an array of capacitors, including a pair of capacitors (C4, C5) and a voltage variable capacitor (varactor) (D), a switch (S3), and a tuning coil (L). When the switch is in the open position, the pair of capacitors are connected in parallel with the varactor. When the switch is closed, the pair of capacitors are connected to ground, arraying themselves on opposite sides of the varactor. In this closed position, the overall capacitance of the tuned circuit increased, thus lowering the tuned frequency of the circuit. Since the switched capacitance (i.e., the capacitance which changes the tuned frequency of the circuit) is arrayed on both sides of the varactor, the varactor maintains its relative sensitivity.

Abstract: A method of producing a gel of an organic liquid, using a metal phosphate ester in which all of the reagents are substantially free of water and pH-affecting substances. The gel is particularly useful in fracturing subterranean formations by entraining a solid particulate proppant therein and pumping the resultant mixture into the subterranean rock formation at sufficient pressure to fracture the formation. The organic liquid is preferably a hydrocarbon such as diesel or crude oil, and the metal phosphate ester is preferably an aluminum phosphate diester. The metal phosphate diester may be prepared by the reaction of a triester with P₂O₅ to produce a polyphosphate, which is then reacted with an alcohol to produce a phosphate diester. The latter diester is then added to the organic liquid along with a non-aqueous source of aluminum, such as aluminum isopropoxide in diesel, to produce the metal phosphate diester. The conditions in the foregoing two reaction steps are controlled to provide a gel with good viscosity versus temperature and time characteristics.

Abstract: A broad band, thin film attenuator. An attenuator for microwave circuits is constructed by placing a ground plane conductor on one side of a ceramic, insulating substrate, and conductive, resistive, and reactive elements on the other side of the substrate. Capacitive stubs are provided to compensate for inductance in a grounding conductors between resistance elements and the ground plane conductor. Constrictions are provided in input and output conductors to provide increased series inductance to compensate for distributed capacitance of the resistance elements. One resistance element is constructed so that the interface between the input conductor and that resistance element forms an obtuse interior angle with an adjoining transitional edge extending from the input conductor to the grounding conductor, and the transitional edge formsan obtuse interior angle with the adjoining edge of the grounding conductor, so as to minimize current density concentrations and distributed capacitance. A second resistance element is employed to achieve additional attenuation.
