Title: Helicoidally finned tubes
Inventor: BODAS JANOS
IPC: F28F1/36
Filed: 1983-04-06
Granted: 1986-03-13
Abstract: A helicoidally finned tube for use mainly in heat exchangers. The tube comprises a cylindrical tubular member which carries or is integral with a helical member the turns of which form the fins of the tube. The fins are provided with ripples which extend from the outer rim of the fins inwardly and the depth of which diminishes toward the tube center. The ripples serve for diverting a cooling medium inwardly to hotter parts of the tube thereby improving its heat transfer performance. The helicoidal member has rippled sections alternately with level sections, the rippled sections subtending an angle not exceeding about 90 degrees and both types of sections on successive turns registering with one another in the direction of the axis of the tubular member. The spacing of the sections is substantially equal to a quarter of the circumference of the tubular member so that the rippled sections of the helicoidal member occupy diametrically opposed positions on the tubular member, the ripples being disposed generally transverse to the direction of airflow. The ripple-free sections, thus positioned, facilitate removal of impurities precipitated in the fin gaps (FIG. 9).

Abstract: Improved fiber resin matrix prepreg fabrics are disclosed which are comprised of a first layer of reinforcing fabric coated with an epoxy resin composition and a discrete second layer of an epoxy resin modified with an elastomeric polymer. The discrete second layer is provided with a support comprising a gauze-like, lightweight fibrous mat or carrier of light-weight fibers that preserves the second "interleaf" layer during cure. Cured composites having the continuous interleaf layer intact exhibit high impact strength and resistance to impact damage. In addition, high-performance fiber resin matrix composites are disclosed which are comprised of a first layer comprising reinforcing filaments coated with a thermosetting resin composition and a discrete second layer of a thermoplastic resin. When the composite layers are matched to provide certain minimum strength and elongation properties, composites of unusually high impact strength and resistance to impact damage are achieved which retain their high performance properties over a range of temperatures and environmental exposures.

Abstract: A self-contained detector device for educational or amusement purposes cooperates with conducting and non-conducting zones of a carrier. The detector is in the form of an elongated hollow body with a reading or detecting head projecting from one end. The head is rigidly mounted on a printed circuit board that travels slidably in the hollow body. When the detector is in use on the carrier, pressure causes the head and board to slide up into the body and close a spring switch, energizing a detecting circuit on the board and coupled to the head. The head can favorably be formed as a stack of alternate conducting and non-conducting sheets. The non-conducting sheets can be of an elastomer.

Abstract: To prevent the vibrations caused by wind in suspended-roof supporting frameworks, the suspended-roof supporting framework has main chains composed of bar-shaped main links of relatively small cross section. The ends of these main links are connected to one another at joint centers, and the ends of the main chains are fastened to a stationary perimeter structure. The joint centers of adjacent main chains are connected by means of supplemental links of larger cross section. The supplemental links are larger in cross section than the main links, so they form supplemental chains which are heavier than the main chains. The supplemental chains extend obliquely relative to the main chains, and their ends are fastened to the perimeter structure.
