Inventor: TROXLER ROBERT E
IPC: G01N9/24
Filed: 2001-06-01
Abstract: A nuclear density gauge and test method is provided for measuring bulk density, especially of a cylindrically shaped sample such as asphalt paving material. The gauge comprises a base (12); a sample holder (18) carried by t he base and having a surface configured for receiving and holding a first generally planar end of the cylindrically shaped sample (20); a plate (16) mounted in proximity to said sample holder; and at least three sources of gamma radiation located in said plate adjacent the sample holder. The source s (26) are positioned in spaced-apart relation from one another for emitting gamma radiation from at least three spaced-apart locations into said one end  of the sample. Each of the sources comprises an isotope having a characteristic primary energy. A detector is mounted to the base and is positioned adjacent the opposite end of the cylindrically shaped sample for receiving gamma radiation which has penetrated the sample. Means is provided  cooperating with the detector for calculating the bulk density of the sample  based upon the gamma radiation counts by the detector. Preferably the detect or comprises a scintillation detector (24), and the means for calculating the bulk density of the sample includes an analyzer connected to the scintillati on detector for detecting gamma radiation in a predetermined energy spectrum, which preferably falls within the range of 0.1 MeV to 2 MeV.

Title: Method and apparatus for increasing the effectiveness and efficiency of multiple boundary layer control techniques
Inventor: MOORE KENNETH J
IPC: B63B1/38
Filed: 2001-07-17
Abstract: In an apparatus and method for ejecting an additive for significantly reducing the drag of a first fluid moving relative to a wall, a drag-reducing substance is conditioned by causing a second fluid (5), which includes the drag-reducing substance as a dispersed solid, liquid or gas, to flow through a nozzle (13).  The second fluid is then passed by a vortex chamber (4) prior to ejection of the second fluid into the first fluid via an aperture that includes a Coanda surface (8) on a portion thereof. Additional techniques are also disclosed which increase the effectiveness and efficiency of ejecting a drag-reducing substance into a fluid that is moving relative to a wall, and which thus enable multiple layer to be established withougt the undersirable disruption of the boundary layer and without the rapid diffusion of the additives across the boundary layer that occur in prior art ejection techniques.

Title: Sleeve for pig-tailing optical fiber
Inventor: MARK JOHN G
IPC: G02B6/30
Filed: 2001-07-28
Abstract: A sleeve (22) enables attachment of an optic fiber (14) to a multi-integrated optic chip (10) in optical communication therewith, and maintains alignment of the fiber at its end adjacent the chip. The sleeve includes a symmetrically-shaped cavity (26) bounded by termini (30, 32) which are respectively disposed to fit onto the chip and to accept the fiber. An adhesive (46) within the cavity symmetrically bonds the fiber to the chip. The adhesive curs symmetrically in the cavity, to eliminate undersired motion of the fiber from its preferred alignment position vis-a-vis the chip connection point (12) or to provide a repeatable motion to achieve the optimum alignment position of the fiber with respect to the chip. The sleeve controls, defines and confines the index matching adhesive and/or fluid between fiber end (44) and connection point (12) by defining the areas and volume actually in contact with the adhesive or fluid. Symmetry is preserved over the effects of gravity and wicking which heretofore have prevented a very symmetrical pigtail which is necessary for performance and repeatability.

Abstract: An improved energy absorbing and impact attenuating module comprising multip le layers of energy absorbing cores, panels or articles fused or bonded together by common facin g sheets or otherwise fixed or positioned adjacent or in juxtaposition to one another to form an integral module each layer comprising honeycomb, foam or other energy absorbing materials. The properti es of the energy absorbing layers are designed and produced with a variation in physical properties such as thickness, density, crush and compressive strength to provide a specified no n- progressive crush sequence of layers or segments of layers and specified compound load (stress ) versus deflection (strain) response upon impact as the layers of the module crush. The successive layers in the crush sequence are positioned preferentially maximally distal to one another in th e module. The module of the present invention is more efficient and effective than energy absorbi ng articles of prior art by incorporating multi-phase energy absorption, designated deceleration and attenuation of the impacting body, and transfer and reflection of impact energy within and between layers or segments of layers of the module. The energy absorbing and impact attenuating respons e of the module can be designed specifically for a wide range of impact energies and variety of applications including an impact-absorbing barrier for racecars, highway barriers, automobile bumper systems, automobile chassis components, interior and door panels, crash and sports helmets, safe ty and protective equipment, protective clothing and the like.
