Abstract: Members of the InK4 (Inhibitors of CDK4) family inhibit the activities of specific cyclin D-dependent kinases (CDK4 and/or CDK6), thereby arresting cell cycle progression in G1 phase and preventing chromosomal DNA replication. Disclosed herein are novel mammalian InK4 family members, having apparent molecular masses of 18,000 and 19,000 daltons, designated "InK4c-p18" and "InK4d-p19", respectively, or simply "p18" and "p19". In particular, the invention provides p19 genes and proteins isolated from murine or human cells and p18 genes and proteins from murine cells.

Title: High opacity tipping paper
Inventor: MAHONE KERRY A
IPC: D21H27/00
Filed: 1997-10-01
Abstract: The present invention is directed to a tipping paper adapted for wrapping a filter of a smoking article. The tipping paper contains a pigment made from calcium carbonate particles having a median size of between about 0.1 microns to about 0.5 microns.      The calcium carbonate pigment can be used to create a tipping paper having an opacity of up to at least 89%.      In comparison to conventional tipping papers, it has been surprisingly discovered that the tipping paper of the present invention reduces knife wear of a cutting instrument used to cut the paper and is less retentive to solvents when the paper is printed with a solvent based ink or covered with a solvent based coating.

Patent CA-2218882-A1 (CA)
Title: Stabilization of water
Inventor: DE VILLIERS HENDRIK ABRAHAM
IPC: C02F5/08
Filed: 1996-04-18
Abstract: The invention provides a process for the stabilization of raw water having a pH of 2,5-9, an alkalinity of at most 50 mg/l expressed as calcium carbonate, a calcium content of at most 100 mg/l expressed as calcium carbonate, and a positive calcium carbonate dissolution potential. The process comprises separating part of the water from the remainder thereof and acidifying said part to increase its calcium carbonate dissolution potential. The acidified water is then fed through a bed of particles comprising calcium carbonate where said water consumes part of the calcium carbonate thereby increasing the calcium content and the alkalinity of the water which issues from the bed. The water issuing from the bed is then mixed with the remainder of the raw water to obtain an at least partially stabilized product water having a positive calcium carbonate dissolution potential which is at least 2 mg/l calcium carbonate less than that of the raw water.
Patent CA-2220725-A1 (CA)
Title: Hydroentangled nonwoven composites
Inventor: KEPNER ERIC SCOTT
IPC: D04H13/00
Filed: 1996-06-03
Abstract: Disclosed herein is an entangled nonwoven composite made from absorbent fibers such as wood pulp fibers and matrix fibers such as polyolefin staple fibers.  The absorbent fibers are entangled with the matrix fibers in such a manner so that the composite has an absorbent-rich side and a matrix-rich side.  Intermediate the two exterior sides there is an entangled interior portion made from a mixture of the absorbent and matrix fibers. The composite is particularly well-suited for use in multifunctional handling of fluids such as, for example, body fluids which are absorbed by personal care absorbent articles. The matrix fiber portion of the composite acts as a fluid intake region while the absorbent fiber portion acts as a fluid retention region and the portion of the composite intermediate the two exterior surfaces acts as a fluid transfer region.

The endoscopic component of the device may also be utilized to visually observe the use and/or effect of one or more separate device, such as valvulotome(s) used for cutting venous valves located within the lumen of a vein.
Patent CA-2224038-A1 (CA)
Inventor: NOSE MASAYOSHI
IPC: H04L12/801
Filed: 1997-12-08
Abstract: In an ATM network, a database is provided in a network controller for holding data pertaining to network topology and remaining network resource. The controller has a supervisory circuit that constantly monitors communication links between ATM switches. Route decision and resource reservation logic circuitry updates the database if a network failure condition is detected by the supervisory circuit. The logic circuitry also receives, from a source terminal, a reservation request indicating a reservation of an end-to-end network resource between a scheduled start time and a scheduled end time, and makes a search through the database to reserve the network resource in the database if the network resource is available. The logic circuit causes the ATM switches to establish an end-to-end connection using the reserved network resource at the scheduled start time, informs the source terminal of a VCI/VPI of the established connection for subsequent transmission of messages, releases the established connection when the request in the registration memory indicates the scheduled end time, and removes the request from the registration memory. The logic circuit also accommodates class of service requests; for a first class, the database is searched, and requested resources are reserved at the time the request is received. For a second class, the search is not performed until the scheduled start time.
Patent CA-2225700-A1 (CA)
Inventor: KRANTZ WILLIAM DOUGLAS
IPC: B60K17/10
Filed: 1997-12-22
Abstract: A neutral by-pass for hydraulic fluid in a hydrostatic transmission is provided by an essentially closed conduit comprising a pair of bores and a channel communicating the pair of bores, all formed in the cam ring of the transmission.When the neutral point is attained, the bores will be communicated with oil dampening pistons in communication with the hydraulic fluid supply passages and the fluid pressure between the passages will be equalized. This will operate from either the forward or reverse direction. As the cam ring is angularly moved, essentially closed conduit is moved away from the dampening pistons, so there can be no fluid flow therethrough. When this occurs, all fluid flow goes to the motor rotor, causing output rotation.

Title: Code generating system for imporved pattern matching in a protocol analyzer
Inventor: KELLEY JEFFREY V
IPC: H04L12/26
Filed: 1998-01-09
Abstract: A machine code generating system for improved pattern matching in a protocol analyzer. The code generating system includes a pattern relationship analysis phase and a pattern matching code generation phase. The pattern relationship analysis phase includes evaluating pairs of test patterns to determine the relationship that exists between each pair such as superset, subset, independent, external, and identical. The pattern matching code generation phase includes generating general pattern matching code in addition to generating specialized comparison code that is specific to the types of relationships that exist among a given set of patterns. The machine code that is generated, organizes the patterns into groups to minimize the number of pattern matching comparisons required to a minimum defined in the average case as the sum of the number of patterns and the maximum number of words per pattern. The machine code generated by the code generating system is ready to execute at the completion of the code generating system operation.
