Patent CA-2246038-A1 (CA)
Title: Tire tread compound
Inventor: HALASA ADEL FARHAN
IPC: C08L15/00
Filed: 1998-08-27
Abstract: This invention relates to a tire tread compound that is easily processable which can be used to improve the treadwear, rolling resistance and traction characteristics of tires.  The tire tread compounds of this invention are a blend of tin-coupled polybutadiene, high vinyl polybutadiene and natural rubber.  This blend of low glass transition temperature rubber and high glass transition temperature rubber is surprisingly easy to process which makes the concept of this invention commercially feasible.  Thus, the tire tread compounds of this invention can be utilized in making tires having greatly improved traction characteristics and treadwear without sacrificing rolling resistance. These improved properties may be due, in part, to better interaction and compatibility with carbon black and/or silica fillers.  The polybutadiene in the blend can be asymmetrical tin-coupled to further improve the cold flow characteristics of the rubber blend. Asymmetrical tin coupling in general also leads to better processability and other beneficial properties. This invention more specifically discloses a tire tread rubber composition which is comprised of (1) from about 20 phr to about 60 phr of tin-coupled polybutadiene rubber,  (2) from about 20 phr to about 60 phr of a rubber selected from the group consisting of natural rubber and synthetic polyisoprene and (3) from about 5 phr to about 40 phr of high vinyl polybutadiene rubber.

Title: Simplified keyboard and electronic musical instrument
IPC: G10H1/18
Filed: 1996-06-26
Abstract: Disclosed is an electronic musical instrument comprised of operators organized in repeating patterns of seven. The operators are electronically interpreted to correspond only to the valid notes of a selected scale.      The repeating patterns of seven notes directly corresponds to the vast majority of music theory and thus constitutes an enormous simplification in the art of learning, performing and composing music. The present invention enables users of the electronic musical instrument to master chord and note progressions in any scale and mode by learning only a single set of note patterns, in contrast to the myriad scales, chord and note patterns which must be learned on traditional keyboard and pedal devices.

Title: Uniform dispensing multichamber tubular containers
Inventor: PRENCIPE MICHAEL
IPC: B65D81/32
Filed: 1997-05-21
Abstract: A multichamber container must have certain characteristics in order to uniformly dispense the contents of each chamber from the container. The outer wall of the container and the inner divider web walls must have certain characteristics. The inner divider web walls must be highly flexible while the outer container wall must be less flexible.  The Deflective Force for the outer wall must be greater than the Deflective Force for the web walls. In addition, to alleviate the problem of suckback of air into the container chambers, the outer wall should exhibit a specific Retention Index. This is a measure of the outer wall to remain deflected after the removal of the deflecting force. The inner divider web wall will have a lower Retention Index than the outer wall. By the proper selection of outer wall and web walls, there can be uniform dispensing from the dispenser.

Title: Hollow frustum reagent test device
Inventor: PUGH JERRY THOMAS
IPC: B01L3/00
Filed: 1999-01-08
Abstract: A hollow, frustum-shaped disposable device is used in an apparatus for measuring the concentration of an analyte in a sample of a biological fluid.  The smaller end of the frustum his a porous membrane, to which a sample of the fluid may be applied. Preferably, a reagent in the membrane reacts with the analyte to cause a color change. The device is mounted on a meter, which measures the color change and computes from the change the analyte concentration in the sample.  The apparatus permits remote dosing of the device, which minimizes the likelihood of cross-contamination between the user and the meter. Devices can be mounted on the meter and released from the meter without touching them, to further protect against contamination.
