Title: Delay mechanism for retarding relative movement between two members
Inventor: HASSLER STEPHEN P
IPC: E05D3/00
Filed: 1994-12-23
Abstract: Abstract of the Disclosure A delay mechanism for retarding relative movement between two members has particular application in a hinge assembly for a dropout fuseholder. In one embodiment, a pin member rotatably connecting two adjacent members is disposed through a sleeve which has a cavity filled with viscous material, such as silicon putty. Protrusions extending from the shaft of the pin engage the putty and retard the relative rotational movement of the two members. In another embodiment, a friction member, such as a washer or annular seal, is disposed between the adjacent rotatable members. The friction member has facing surfaces contacting the opposing surfaces of the rotatable members such that the frictional forces between the friction member and the rotatable members retard rotation. In still another embodiment, the hinge assembly of a dropout fuseholder includes a latch member which rotates away from the fuseholder once dropout is initiated. As this occurs, the latch member draws a plug member through a putty-filled chamber in the fuseholder. The plug member includes extending projections which engage the viscous putty to retard rotation of the latch member. Additionally, dashpot devices may be employed between the various members of the hinge assembly to retard relative movement.

Title: Yeast-leavened refrigerated dough products
Inventor: DOMINGUES DAVID J
IPC: A21D10/02
Filed: 1994-03-04
Abstract: The present invention provides refrigeratable yeast-leavened dough compositions and methods of making such doughs. The dough's composition and the strain of yeast used therein are chosen to limit the total leavening action of the yeast by controlling the amount of substrate in the dough fermentable by the yeast or by inactivating the yeast at high temperatures. Dough compositions made in accordance with the invention are capable of being leavened at elevated temperatures, yet stored in a sealed container at refrigeration temperatures for extended periods of time. In a preferred embodiment the yeast used in the dough is substantially incapable of fermenting carbohydrates native to the dough and a predetermined quantity of a non-native carbohydrate fermentable by the yeast (e.g. galactose) is added to the dough to provide the desired amount of proofing. A diploid yeast is further provided with the further property of being inactive at low temperature.

Title: Assay and reagents for identifying anti-proliferative agents
Inventor: DRAETTA GIULIO
IPC: G01N33/50
Filed: 1994-06-06
Abstract: The present invention makes available assays and reagents for identifying antiproliferative agents, such as mitotic and meiotic inhibitors. The present assay provides a simple and rapid screening test which relies on scoring for positive cellular proliferation as indicative of anti-mitotic or anti-meiotic activity, and comprises contacting a candidate agent with a cell which has an impaired cell-cycle checkpoint and measuring the level of proliferation in the presence and absence of the agent. The checkpoint impairment is such that it either causes premature progression of the cell through at least a portion of a cell-cycle or inhibition of normal progression of the cell through at least a portion of a cell-cycle, but can be off-set by the action of an agent which inhibits at least one regulatory protein of the cell cycle (e.g., cdc25) in a manner which counter-balances the effect of the impairment.

Title: Fish landing net with telescoping handle
Inventor: BOEHM GEORGE L
IPC: A01K77/00
Filed: 1996-05-28
Abstract: The disclosed fish landing net includes a telescoping handle movable with respect to two handle-engaging "mirror image" lock pieces, each of which has a pair of interior grooves. When the net is in use or when the handle is being telescoped toward the distal portion, each groove of each lock piece is in registry with the corresponding groove of the other lock piece. Axial ridges on the handle engage respective pairs of grooves and prevent relative rotating movement between the handle and the lock pieces. A release portion at the outer end of the handle permits the lock pieces to be rotated with respect to such handle when the net is being folded or unfolded. The net also includes a locking member preventing telescoping handle movement when the net is erected ready for use.
Patent CA-2179570-A1 (CA)
Title: Event or novelty detection
Inventor: SCARTH GORDON B
IPC: G06K9/62
Filed: 1996-06-20
Abstract: A significant problem is unsupervised detection of events in the digital image representation of objects or bodies acquired at logically different states. To detect events a set of sample data points is selected, and normalized using a novel technique to desensitize the analysis to the intensity level of the data. The normalized data are presented to a clustering algorithm, preferably the fuzzy C-Means clustering algorithm which groups the data into a user-specified number of clusters. The resulting clusters are not affected by human bias or preconceived notions, since the process is independent of prior knowledge of the events. The cluster centroids identify the characteristics of the events and the cluster maps depict the image domains associated with the events. The invention is equally applicable to normal and abnormal events and is capable of detecting expected and unexpected results.
