Patent CA-2297472-A1 (CA)
Inventor: JACKSON DANE R
IPC: A61F13/26
Filed: 2000-01-28
Abstract: An applicator is provided that has a textured finger grip. The textured finger grip is formed by exposing the applicator barrel to a beam of a laser to form deformations in the applicator barrel surface. The textured properties of the laser engraved finger grip of the present invention are enhanced when protuberances are superimposed on laser engraved areas by conventional embossing techniques. In addition, it is disclosed that effects of conventional embossing techniques are improved by embossing over areas that have been previously been exposed to a beam of a laser. Processes for manufacturing applicator barrels having the aforementioned textured fingergrips are also provided.

Title: Method of determining conifer embryo maturity using sugar alcohol content
Inventor: KOESTER MARTHA K
IPC: A01H7/00
Filed: 2000-02-07
Abstract: The invention relates to the knowledge of sugar alcohols as indicators of biochemical maturity of pine zygotic and somatic embryos. It has been discovered that loblolly pine zygotic embryos have a progression of different sugar alcohols as they approach biochemical maturity. Pinitol is the first sugar alcohol to appear in abundance. This is followed by D-chiro-inositol, and finally by fagopyritol B1. As a later appearing alcohol becomes more abundant in the embryos, the earlier ones decrease in amount present. Analysis of the embryo sugar alcohols can be helpful in determining when to harvest cones from seed orchards. Further it can be used as a guideline for formulation of more effective culture media in the propagation of somatic embryos by tissue culture. There appears to be a requirement for fagopyritol B1 if good germination of somatic embryos is to be achieved.

Title: Method and apparatus for forecasting and controlling congestion in a data transport network
Inventor: KUNG HSIANG T
IPC: H04L12/56
Filed: 2000-02-22
Abstract: A method and apparatus for controlling congestion at a node in a data network. The node includes an input for receiving traffic units from the network, an output for releasing traffic units to the network and a control unit. The control unit is responsible for estimating a level of data occupancy of at least a portion of the network by looking at the traffic units received at the input from a remote node in the network. When the data occupancy level reaches a certain threshold, the node issues a control signal to the remote node such that the remote node lowers its rate of traffic units input in the network. By estimating the network data occupancy level, congestion at the node can be effectively foreseen and controlled.

Title: Preparation of solutions of betane
Inventor: WALLER FRANCIS JOSEPH
IPC: C07C229/08
Filed: 2000-02-28
Abstract: Betaine is produced by the oxidation of a choline salt in the presence of a base and a supported noble metal catalyst at temperatures from about 20°C to 100°C and pressures from atmospheric to about 100 psi. This process is advantageous over prior processes for the production of betaine in that no amine halocarboxylate contaminants are produced by this reaction.

Title: Deflector for controlling entry of cooling air leakage into the gaspath of a gas turbine engine
Inventor: VALENTINI VALERIO
IPC: F01D11/00
Filed: 1999-03-22
Abstract: The invention provides a deflector for redirecting cooling air leakage to improve the effi-ciency of a gas turbine engine. A  conventional gas turbine engine includes a forward stator assem-bly and a rotor assembly with an air cooled rotor disc, and a cir-cumferential array of blade re-tention slots. An array of air cooled rotor blades with blade bases are retained in each slot.  The rotor blades are disposed equidistantly about the circum-ference of the rotor disc with a radially extending gap between each adjacent rotor blade. It is the significant detrimental ef-fect of cooling air leakage into these gaps, which is the focus of this invention. The invention relates to providing a deflector, disposed circumferentially on a forward face of the coverplate, for deflecting cooling air leak-age, flowing from the running seal through the cooling air leak-age path, away from the gaps be-tween the blades, onto the out-ward surface of the blade platform, and into the gaspath at an acute angle relative to rearwardly axial flow therein.

Title: Method for forming a biological stent
Inventor: STERZER FRED
IPC: A61F2/84
Filed: 1999-07-27
Abstract: The invention is a method for creating a "biological stent" in a tubular structure (e.g., the urethra). The biological stent is created by situating a microwave balloon device (100) in the urethra of the patient in proximity to the prostate gland, inflating the balloon (112) to apply sufficient squeezing pressure on urethral tissue to effect a certain amount of temporary widening of the urethra, and heating the narrowed bore of the urethra (preferably by employing a microwave generator having a transmitter (110) located in the balloon) to make permanent the widening of the urethra due to the formation of a biological stent. The heating, and elasticity of urethral tissue may be monitored to determine when sufficient energy has been delivered to the urethral tissue.
