Patent CA-2219715-A1 (CA)
Title: Synthesis of macrocyclic polymers having low hysteresis compounded properties
Inventor: HALL JAMES E
IPC: C08F8/00
Filed: 1997-10-29
Abstract: The present invention provides a method of anionic synthesis of stable macrocyclic polymers that are compounded to form vulcanizable elastomeric compounds exhibiting reduced hysteresis properties. Cyclic organometallic compounds containing divalent metal atoms of Groups IIA and IIB of the Periodic System are employed as initiators of anionic polymerization of conjugated diene, vinyl aromatic and/or triene monomers. Coupling of the living ends of the resulting macrocyclic polymers or copolymers with a coupling agent or a coupling agent that is also a functionalizing agent results in stable macrocyclic polymers with improved hysteresis properties.

Abstract: The winding of tape into pads is effected on a machine which controls the tension in the tape as it is laid onto the pad by a lay-on roller which also drives the rotation of the pad.  A pad is a spiral winding of tape in which each turn of tape is laid directly on top of the previous turns.  The machine includes a series of cores one for each tape mounted on a shaft for independent rotation of each core relative to the shaft.  The tape is directed from common guide rollers to a series of individual arms one for each tape with each arm being mounted on a shaft for individual adjustment along the length of the shaft to a position associated with the particular core.  The shaft drives a lay-on roller at an outer end of the arm and the arm can pivot about the shaft to accommodate changes in diameter of the package as built. The use of lay-on rollers which are all driven at the same speed ensures a constant tension in the tapes even if the tapes are deviated outwardly so as to increase the spacing between the tapes relative to the original web from which the tapes are slit.

Abstract: An apparatus and method for placement of a tubular body in the urethra. The tubular body includes a proximal portion adapted for placement toward a bladder end and bladder neck end of the urethra and a distal portion opposite from the proximal portion. A sensor component located on the tubular body is responsive to a feature of the urethra and outputs a first signal indicating proper placement of the proximal portion of the tubular body relative to the bladder and bladder neck. Preferably an insertion tool is used during positioning of the urethral apparatus. The insertion tool is coupled to the distal end of the urethral apparatus and is used to push the urethral apparatus proximally in the urethra. The first signal can be transmitted from the urethral apparatus through the insertion tool from which it is perceivable by the person positioning the urethral device. Upon proper placement the insertion tool is decoupled from the urethral apparatus and withdrawn leaving the urethral apparatus in place in the urethra with the proximal portion properly positioned relative to the bladder neck and bladder.

Title: Lignin-based pest control formulations
Inventor: BEHLE ROBERT W
IPC: A01N63/40
Filed: 1996-12-05
Abstract: The present invention provides pest control formulations which comprise lignin as well as methods of protecting pest control agents from environmental degradation through the use of lignin. A solubilized lignin solution is prepared by mixing water, lignin, and a pH adjuster to form a solubilized lignin solution having a pH of between about 7 and about 12, preferably between about 8 and about 11, and most preferably between about 9 and about 10. The solubilized lignin solution is then used to prepare the pest control formulation by mixing with pest control agent and a multivalent salt and drying to form a dispersible formulation. The dispersible formulation is mixed with water to form the pest control formulation having resistance to solar degradation. Alternatively, the solubilized lignin solution may be used as an adjuvant by drying and later adding the dried adjuvant to pest control agent and a multivalent salt to form the pest control formulation, or by mixing directly with pest control agent and multivalent salt to form the pest control formulation. When prepared with the lignin adjuvant, the pest control formulation has improved resistance to washoff as well as resistance to solar degradation.

Title: Directional tail transfer threading apparatus
Inventor: HILKER DIETER H
IPC: D21G9/00
Filed: 1998-11-18
Abstract: A directional tail transfer apparatus includes a tray that defines a longitudinal path line extending along the tray overwhich a paper tail to be threaded travels. The longitudinal path line of the tray is positioned adjacent a first section in a papermaking machine where the paper tail exits. The longitudinal path line is aligned with the initial path of movement of the paper tail. The tray has with one or more creases, which extend across the tray width and bisect the longitudinal path line to effect a natural change in direction of the longitudinal path line through the tray. At least one of the creases bisects the longitudinal path line at predetermined angles other than 90 degrees to provide a lateral displacement in the portion of the tray that follows this crease. This one crease allows the paper tail to fold along its width on an angle that is not perpendicular to the natural downstream path of travel of paper tail. As a result the paper tail changes direction to follow the tray along the longitudinal path line. The fold angle of the creases and lengths of the tray portions pre-selected to accurately deliver the paper tail to a threading nip. The tray further includes an air or gaseous flow source for directing an air-cushioning stream over the tray to pull or draw the paper tail over and along the tray surfaces. The tray is operable at all angles of installation, including an inverted position.

Title: Firefighter's roof support
Inventor: BOUWKAMP JACK
IPC: E04G3/26
Filed: 1998-12-30
Abstract: This invention provides a roof support upon which a fire-fighter or other user can stand. The support fits tightly against a sloped roof, thus the support is wedge shaped. At the upper portion of the support is a standing surface upon which the user will be supported. The roof support is locked into place on a sloped roof by inserting a T-bar attached to a chain into a hole in the roof. Once the T-bar is inserted, it is pulled up against the inner surface of the roof and locked into place by attaching a plug on the opposite end of the chain to a locking device on the roof support.
