Title: Surgical router
Inventor: FUCCI JOSEPH
IPC: A61B17/32
Filed: 1994-08-31
Abstract: ABSTRACT A surgical router for cutting anatomical tissue includes an outer tubular member and an inner member rotatably disposed in said outer member and having a pair of router blades disposed distally of a distal end of the outer member and equally spaced about a longitudinal axis of the inner member and a pair of flutes disposed between the router blades. The flutes have bottoms and sides transverse to the flute bottoms, with the flute bottoms angularly intersecting a passage in the inner member to form aspiration ports within and integral with the flutes. The router blades have leading walls, trailing walls and clearance walls with a width between the trailing walls that is tapered in a distal direction. The leading walls correspond to the flute sides and are curved about the inner member axis in the direction of rotation of the inner member in the outer member. End and side cutting edges are disposed along the leading walls with the end cutting edges being curved about the inner member axis in accordance with the curvature of the leading walls, and the side cutting edges extending longitudinally, helically along the inner member. Center cutting surfaces join the clearance walls and the leading walls at notches at the inner member distal end, and the junctures of the center cutting surfaces with the clearance walls define center cutting edges angled from the end cutting edges in the direction of rotation of the inner member in the outer member.

Title: Methods for the regulation of plant fertility
Inventor: TAYLOR LOVERINE P
IPC: C07H21/04
Filed: 1993-03-05
Abstract: Plants in which flavonol activity has been impaired are conditionally male fertile (CMF), and male fertility can be rescued or restored by providing fertility restoring flavonols at pollen sites in the plant. Although viable pollen is produced by flavonol deficient plants, pollen germination and tube growth are severely reduced both in vivo and in vitro, resulting in plants which are self sterile. However, by contacting pollen of the plant with an amount of a fertility restoring flavonol effective to enhance germination of the pollen, full pollen germination and tube growth may be restored. Useful fertility restoring flavonols include compounds of formula (I), wherein R1, R2, R3, R4, R5, R7, and R8 are hydrogen, hydroxyl or alkoxy having from 1 to 3 carbon atoms. Particularly preferred flavonols include galangin, kaempferol, iso-rhamnetin, quercetin and morin.

Abstract: A method of producing, on a physical medium, a gradient tonal representation of an image and a printhead for producing the same.  An input image is divided into first and second regions.  First, continuously variable intensity level, continuous tone and second,  discretely variable intensity level, half-tone portions of the representation which respectively correspond to the first and second regions of the image are then printed by depositing selected quantities of ink on the first and second portions of the physical medium such that each pixel thereof has an ink intensity level corresponding to the image intensity level for the corresponding one of the pixels of the first region of the image.  The ink is deposited on the second portion of the physical medium by depositing a spot of ink having a first diameter on selected ones of the pixels of the second portion, depositing a spot of ink having a second diameter on others of the pixels of the second portion and depositing no ink on still others of the pixels of the second portion such that the second portion of the representation has the desired ink intensity level.  The color of the ink ejected may be black, in which case, the gradient  tonal  representation  produced  thereby shall be a gray scale representation, or other color such as yellow, cyan or magenta.

Title: Waste recycling system
Inventor: TOWNE GARY A
IPC: F23G5/16
Filed: 1994-10-17
Abstract: A waste recycling system which separates the reusable components within waste such as tires by incomplete burning followed by a series of separation steps. The incomplete burning is carried out within a chamber (40) having at least two hollow perforated rollers on which the waste is supported. The tires are ignited and caused to smolder within the chamber (40), allowing gaseous and vapor by-products to be released (92) and travel downward into the rollers. Inorganic solid matter remaining from the combustion process continuously falls between the slowly rotating rollers into a removal bin or conveyor. The gaseous combustion by-products are directed through an oil bath filter (90) having a mesh on which sprayers apply a cooling oil mist to capture the oil vapor. The remaining hydrocarbon emissions are burned incompletely (120), and the resulting carbon black within the effluent filtered out (123). The effluent is then completely combusted (125) generating heat and then scrubbed (124) to emit a relatively clean gaseous discharge (129).

Title: In home oral fluid sample collection device and package for mailing of such device
Inventor: BAHL CHANDER
IPC: A61B10/00
Filed: 1996-03-27
Abstract: This reagent strip is comprised of a testing portion which contains an absorbent cotton pad. This absorbent cotton pad may be placed in the mouth on the tongue to collect an oral fluid sample. A plastic frame surrounds the pad to help hold the fluid thereon. This testing strip contains at its opposite end a sealing mechanism for sealing engagement with a preservative pouch, and an oversized handle with a patient identifying mechanism. The preservative pouch of the present invention contains a pair of seals. The first seal, located proximally to the user, enables a preservative which is maintained within the pouch to be sealed during shipment of the pouch to the user. Thereafter, the user punctures the first seal upon placement of the reagent pad into the pouch. The sealing mechanism contained on the reagent pad then seals at the opening in the pouch to maintain the reagent pad in sealing arrangement within the pouch. At its distal end, the pouch contains a second sealing mechanism. This sealing mechanism helps protect the preservative as well as the oral sample, within the pouch during shipment from the user back to the testing laboratory.
