Title: Method for thawing frozen road culverts
Inventor: STERLING ROBERT LAUREL
IPC: E01F5/00
Filed: 2000-03-10
Abstract: A method for thawing frozen road culverts which includes the following steps. A first step involves providing a collapsible tube having an interior cavity and opposed ends. The opposed ends are closed by fluid impervious end closures. A second step involves positioning the collapsible tube in a road culvert prior to an ice blockage occurring. One of the opposed ends is positioned upstream of an anticipated ice blockage site and the other of the opposed ends positioned downstream past the anticipated ice blockage site. A third step involves applying a vacuum to the collapsible tube until the collapsible tube collapses. This creates a void in an ice blockage adjacent to the collapsed collapsible tube which serves as an immediate flow channel.

Title: Tintable luminescent paint
Inventor: VAN DUYNHOVEN DEBRA M
IPC: C09D5/22
Filed: 2000-06-01
Abstract: By combining alkali earth oxide aluminate phosphors with an alkyd base, a rheology improver, another pigment, an anti-skin additive, and other ingredients, one can achieve a luminescent paint that has characteristics including tintability, applicability, viscosity, appearance and coloration comparable to a non-luminescent paint, with adequate protection from moisture and at a relatively reasonable cost. An alkyd base formulation is the preferred formulation that will allow for the highest amount of loading without compromising the quality of the paint with respect to appearance or applicability. The appearance of the paint in daylight has minimal orange peel or pockmark affects because of the ability of this formulation to suspend and diffuse the large luminescent particles effectively while applying the product. In addition because of the effectiveness of this formulation the appearance of the glow is even, consistent and undisrupted in a properly installed scenario. This product is non-abrasive and will provide a smooth, even appearance.

Inventor: FENNELL SCOTT
IPC: A63C13/00
Filed: 2000-05-24
Abstract: A device to enable a person to move on the snow. A plate has an upper and a lower surface. A binding is attached to the upper surface and can receive and secure the foot of a wearer. A unidirectional slip material is attached to the lower surface. This material allows the person wearing the device to slide the plate in one direction but resists the tendency to slide in the opposite direction. The device is an improvement over snow shoes in that it can be slid over the snow, if desired, in one direction and will also allow the wearer to climb quite steep slopes because of its resistance to sliding in the opposite direction.

IPC: G01N33/50
Filed: 1999-04-01
Abstract: The present invention relates to a method of identifying an agent which alters (inhibits, enhances) activity of GDF-9. The method involves combining cells having a receptor for GDF-9 and a gene, wherein expression of the gene is regulated by binding of GDF-9 to the receptor; GDF-9; and an agent to be assessed. The combination produced is maintained under conditions appropriate for binding of GDF-9 to the receptors on the cells. The extent to which binding of GDF-9 to the receptors on the cells occurs is then determined, wherein binding of GDF-9 to the receptor to a lesser or greater extent in the presence of the agent to be assessed than in its absence, is indicative of an agent which alters GDF-9 activity.
