Title: Therapies using hemoproteins
Inventor: HAUSLADEN ALFRED
IPC: A61K38/50
Filed: 1999-07-09
Abstract: Herein it is shown that hemoproteins (e.g.Ascaris hemoglobin, myoglobin, flavohemoglobins) have NO-consuming and deoxygenase activities. The invention provides a method of reducing the concentration of oxygen and/or nitric oxide in a mammal. The method of the invention comprises administering a therapeutically effective amount of a hemoprotein having NO-activated deoxygenase activity or an enzymatically active fragment thereof to a mammal.  The method can be used to treat a mammal having pathologically proliferating cells, such as a tumor. The invention further provides a method of treating a mammal infected with Ascaris sp., comprising administering to said mammal a therapeutically effective amount of an inhibitor of NO-synthase. The NO-consuming activity of a hemeprotein (e.g. flavohemoglobin) can be used in a treatment where constriction of blood vessels is desirabel, or where it is otherwise desirable to reduce NO concentration, as inflammation.

Title: Bi-modulus composite seal and its method of manufacture
Inventor: CARR STEPHEN J
IPC: F16J15/32
Filed: 1999-09-03
Abstract: A lip-type fluid seal (10) for a shaft includes a composite sealing lip (26)  having an elastomeric portion (32) and a PTFE portion (36). The elastomeric portion (32) includes a lip edge (33) that extends circumferentially continuously to seal the adjacent lip edge (37) of the PTFE portion (36) fro m any contaminants on the elastomeric side (28) of the seal (10).

Patent CA-2349805-A1 (CA)
Inventor: ROBERSON RUSSELL K
IPC: B27B31/00
Filed: 2001-05-30
Abstract: A spiked H-style link for a sharp chain conveyor where the single centrally-placed saddle of the prior art is replaced by a double saddle with a centrally-located opening shaped to receive a sprocket tooth. The double saddle moves each saddle outward from the central portion of the spiked link to enhance the rigidity of the legs between which the connecting pins act. The legs are provided with a thickened offset step on the lower inner portion of each leg. There is a corresponding decrease in the thickness of the legs in the region where the connecting link works. By decreasing the thickness of the legs in the region outside the offset step, the connecting link may be widened, allowing for a greater bearing surface on the connecting pin and thus reducing the rate of wear on the connecting pin.

Inventor: BISCHEL WILLIAM K
IPC: G09F9/00
Filed: 2000-04-13
Abstract: An integrated optical microstructure includes a substrate (245) carrying an optical waveguide (240) and supporting a medium (210) disposed to receive optical energy from the waveguide. The medium includes an optical re-radiato r such as a phosphor (225), which re-radiates optical energy in response to optical energy received from the waveguide. The structure further includes a  reflector (250, 255, 260) disposed to redirect some of the input optical energy emanating from the medium back into the medium, to achieve spatial confinement of the input light delivered by the input waveguide. The structu re can thereby increase the efficiency of the light conversion processes of re- radiating materials. An aperture (235) in the reflector permits optical ener gy emitted by the re-radiator to emerge from the structure and to propagate in a preferred direction, such as toward a viewer or sensor. The structure is useful for increasing the brightness of various kinds of small emissive elements which are excited by light delivered from an integrated optical waveguide, including pixels in an information display.

Abstract: A golf club has grooves across its face that are angled from an upper face section positioned relatively toward a toe of the club to a lower face section positioned relatively toward the heel with respect to the sole of the golf club instead of being parallel with a sole of the club. The angled grooves cause a sideways spin to be imparted to a struck golf ball. In one application, the angled grooves impart a spin that corrects for what would otherwise be a slice. The grooves can be at different angles, depending upon the golf club and the application. In an embodiment, the low irons and woods will have the grooves at a relatively higher angle than the mid irons, which will have the grooves at a higher angle than the approach irons and wedges.  Clubs having such angled grooves can be structured according to USGA or other rules, but need not be.
