Title: Stacked address transport in connection-oriented networks
Inventor: MCALLISTER SHAWN
IPC: H04L12/56
Filed: 1998-06-11
Abstract: There is provided a method of signalling a message using a terminal address across multiple network entities. At least two contiguous network entities are associated with addressing spaces for which message addresses are not routable by way of the terminal address and are not otherwise mutable by way of a single address. The method involves storing a terminal address of either an originating network entity or a terminating network entity as a party number. The message is routed according to the party number from the originating network entity through each succeeding and contiguous intermediate network entity, if any, which provides an addressing space through which the message is mutable. At every network border between any two contiguous network entities wherein an immediately succeeding network entity does not provide an addressing space through which the message is routable, it is determined whether the party number is to be stored and replaced with a new party number. If so, the party number is stored so as to permit its subsequent retrieval according to a last-in and first-out precedence to thereby create a stored party number. Once the party number has been stored, a replacement address is assigned as the party number. Also at every such border, it is determined whether the party number is to be discarded and replaced with a stored party number. If so, the last-in stored party number is assigned as the party number. The message is then routed according to the party number and, with the message, every stored party number is transported through the immediately succeeding intermediate network entity and through each further succeeding and contiguous intermediate network entity, if any, through which the message is routable. The step of determining whether the party number is to be stored and replaced, that of determining whether it is to be discarded and replaced, and that of routing the message and stored party numbers through succeeding intermediate network entities are all repeated until such time as the message is mutable to the terminating network entity according to the party number.

Title: Compositions and methods for mediating cell cycle progression
Inventor: ROBERTS JAMES M
IPC: C12N5/06
Filed: 1997-01-17
Abstract: Hypercellular nonhuman organisms have functionally inactivated expression of a cyclin inhibitor gene, especially p27. The growth rate of nonhuman organisms are increased such that a desired size is attained more quickly than as compared to nonvariant organisms. Inhibitors of the p27 cyclin dependent kinase inhibitor protein or sequences encoding the protein modulate vertebrate cell cycle progression and increase the proportion of dividing cells to non-dividing cells in a population of treated cells. As the proportion of dividing cells Increases, the cell population, e.g., hematopoietic progenitor (stem) cells, is more efficiently used for gene therapy applications. Transgenic animals and plants, and knockout alleles are provided.

IPC: G03B17/52
Filed: 1997-03-27
Abstract: An instant camera for exposing self-processing photographic film sheets (200) provided in a loose stack within the camera. The camera includes a mechanism for manually extracting each film sheet after exposure. The film extracting mechanism comprises a pair of opposed pressure rollers (310, 320), one of which has a gear pinion (130) meshing with the teeth (152) of a manually operable gear rack (110), and a pick or film gripper (144) provided at one end of the rack. Upon pulling out the rack from the camera body, the pick engages the trailing end of the uppermost film sheet such that the film leading end is moved into the nip between the opposed pressure rollers, which crush a bag, pod containing a film processing liquid developer and spread the liquid on the exposed film sheet surface while the film is being extracted from the camera due to continuated movement of the rack engaging the roller gear. An exposure counter disk (246) is arranged to be engaged by the rack pick and incremented during extraction of the rack. The camera can be a preloaded, single-use camera. The gear rack can be replaced by a continuous belt to be manually actuated by a slidable knob.

Patent CA-2251005-A1 (CA)
Inventor: ARNOLD D BRINK
IPC: B65G15/64
Filed: 1998-01-26
Abstract: A belt (10) for use in a conveyor system has ribs (12, 14, 23, 24, 26, 30) to aid in the training of the belt. The invention comprises a belt (10) with a body (18) having an inner surface (16), an outer surface, and a first set of longitudinal ribs (12, 14, 23) disposed on the inner surface (16) of the belt.  The ribs function to lessen the surface area of the belt contacting a roller (32) of the system during the training period. Accordingly, the new belt adheres to the rollers of the conveyor system less aggressively, reducing lateral coplanar forces having the potential to damage the belt and/or the conveyor system. The height of the ribs with respect to the body diminishes over time due to normal frictional wear during the use of the belt in the conveyor system. In some embodiments, the belt includes a second set of ribs (24, 26, 30) disposed on the outer surface (28) of the belt. The height of the second set of ribs with respect to the body also diminishes over time due to normal frictional wear during the use of the belt in the conveyor system. The sets of ribs may comprise two ribs (12, 14, 24, 26) running along the edges (20, 22) of the belt. A wider belt may require additional ribs (23, 30) located between the two edge ribs. The belt may be used in a system of rollers (32) and training guides (34). The training guides (34) function to maintain the alignment of the belt with respect to the rollers.
