Inventor: KURG ANTS
IPC: G01N21/55
Filed: 2000-04-20
Abstract: Total internal reflection fluorescence is used for imaging biopolymer arrays.  A beam of light (2) is guided into the solid support (1) at a certain angle, evoking total internal reflection in the solid support. A certain portion of light will not reflect from the inner glass surface but penetrate out of the glass as an evanescent wave. It will excite fluorophores incorporated in the biopolymer molecules, contiguously attached to the surface of the support.  Fluorescence thus evoked will be guided to a light sensitive element (7), providing data on the fluorescent molecules attached to the surface of the support. The said detection of fluorescence signals is rapid, taking about 10 seconds per fluorescence channel.

Abstract: An illumination system provides a light output distribution that is ideally suited for home and office applications. The illuminations system (10) generally comprises a solid waveguide (30) and a light directing structure located on a side opposite of the waveguide's light output side (34) for controlling the light output distribution from the illumination system (10).  The light directing structure may be unitarily formed with the waveguide (30) or it may be secured thereto by an interface which provides approximately 100 % contact between the waveguide (30) and light directing structures (40). The light directing structure (40) includes an array (42) of light directing features configured as generally lenticular prisms (48) that extend in a direction substantially perpendicular (i.e., not parallel) to the average direction at which light rays enter and propagate through the waveguide (30).  Each light directing feature defines an included angle that controls the distribution of light output from the illumination system (10) in a first direction. The interface, when provided, controls the distribution of light output from the illumination system (10) in a second direction that is generally orthogonal with respect to the first direction.

Title: Turbine blade to disk retention device
Inventor: FONTAINE MIKE
IPC: F01D5/30
Filed: 1999-11-22
Abstract: The invention provides a turbine blade retention device installed in an axially extending gap between the blade root bottom and the slot floor. The retention device has two parts: a blade root retention clip and a spacer bar.  The clip has an elongated web of a selected web thickness and width less than the width of the slot floor. The clip includes a forward and a rearward transverse flange extending radially outwardly and extending laterally from forward and rearward ends of the web. The flanges serve to engage the forward and rearward faces of the rotor hub disk respectively, and to engage forward and rearward faces of an associated blade root. The height of at least one flange is less than the gap depth to permit conventional sliding installation of the blade root. The spacer bar is installed in the gap between the clip and slot floor to hold the clip radially outward in engagement with the forward and rearward faces of the blade root. The spacer bar has a thickness that, together with the clip web thickness, substantially equals the gap depth. Preferably, the spacer bar extends axially through the gap and has forward and rearward bent over tabs for engaging the forward and rearward faces of the rotor disk hub.

Abstract: The present invention is directed to a method of manufacturing particle board and other fiber board panels of improved structural quality. A known manufacturing method is improved by utilizing at least one endless metal mesh belt which is made from a material with significantly higher thermal conductivity than, but with coefficient of thermal expansion roughly similar to the steel belt. In the method the steel belt and the metal mesh belt are led back together through an insulating tunnel to prevent heat loss. The metal mesh upstream of the infeed into the press area is led to a heating tunnel separate and apart from the steel belt and is heated to a higher temperature difference from the steel belt of at least 40°C and the specific press pressure acting on the furnish mat during the first 80% to 90% of the press time in the continuously operating press is never below 0.3N/mm2.

Title: Improved skew resisting hydrodynamic seal
Inventor: KALSI MANMOHAN S
IPC: F16J15/32
Filed: 2000-04-26
Abstract: A novel hydrodynamically lubricated compression type rotary seal (2) that is suitable for lubricant retention and environmental exclusion. Particularly, the seal geometry ensures constraint of a hydrodynamic seal (2) in a manner preventing skew-induced wear and provides adequate room within the seal gland to accommodate thermal expansion. The seal (2) accommodates large as-manufactured variations in the coefficient of thermal expansion of the sealing material, provides a relatively stiff integral spring effect to minimize pressure-induced shuttling of the seal (2) within the gland, and also maintains interfacial contact pressure within the dynamic sealing interface (18, 32) in an optimum range for efficient hydrodynamic lubrication and environmental exclusion. The seal geometry also provides for complete support about the circumference of the seal (2) to receive environmental pressure, as compared the interrupted character of seal support set forth in U.S. Patents 5,873,576 and 6,036,192 and provides a hydrodynamic seal (2) which is suitable for use with non-Newtonian lubricants.
