Patent CA-2285710-A1 (CA)
Title: Retractable boat line
Inventor: KNIGHT DARREL C
IPC: B65H75/42
Filed: 1999-10-06
Abstract: A retractable boat line for mooring a boat is wound about a payoff reel contained within a stationary housing, which my be mounted beneath the exterior surfaces of the boat, for example within the hull, transom or gunnel. The invention provides a locking mechanism that latches into a guide wall of the payoff reel at a point remote from the edges of the guide wall to rotationally lock the payoff reel relative to the housing. The mooring line can thus be selectively extended to a desired length and remains locked to the selected length until the locking mechanism is disengaged.

Title: Preparation of high activity catalysts; the catalysts and their use
Inventor: CULROSS CLAUDE C
IPC: C07B61/00
Filed: 1998-04-20
Abstract: A process for the preparation of a catalyst useful for conducting carbon monoxide conversion reactions, especially a Fischer-Tropsch catalyst, use of the catalyst for conducting such reactions, especially Fischer-Tropsch reactions, and the composition produced by said process. In the preparation of the catalyst, a solution of a carbohydrate, or sugar, notably a monosaccharide or disaccharide, particularly sucrose, is employed to impregnate and disperse a compound or salt of a catalytic metal, or metals, e.g., copper or an Iron Group metal such as iron, cobalt, or nickel, or in a preferred embodiment both a compound or salt of rhenium and a compound or salt of a catalytic metal, or metals, e.g., copper or an Iron Group metal such as iron, cobalt, or nickel, onto a refractory inorganic oxide support, e.g., titanic. The rhenium, when present only in a small amount permits full and complete reduction of the catalytic metal, or metals, dispersed by the carbohydrate. Higher catalyst activities with lower rhenium loadings are thus achieved than in previous preparations where higher concentrations of rhenium were required to both effectively disperse, and reduce the catalytic metal, or metals, during the preparation. Surprinsingly, as little as about 1/10 of the rhenium is required to accomplish the reduction promotion where the dispersion is effected with the carbohydrate.

Title: Controllable overrunning coupling
Inventor: HARRISON SHARON
IPC: F16D41/12
Filed: 1998-04-28
Abstract: A planar overrunning coupling includes a pair of coaxial, rotatable coupling plates (10, 20) situated in close proximity, and a strut retainer plate (22) disposed therebetween. Struts (38) nominally carried ins recesses (26, 28, 30, 32, 34, 36) formed in one coupling plate (20) are normally urged into engagement with recesses (48) formed in the other coupling plate (10) by a spring (52) disposed beneath each strut (38). The retainer plate (22) includes angularly-spaced apertures (46) such that, when the retainer plate (22) is in a first angular position relative to the one coupling plate (20), a given strut (38) extends through a retainer plate aperture (46) into engagement with the other coupling plate (10). When the retainer plate (22) is in a second angular position relative to the one coupling plate (20), an aperture (46) is no longer registered with the given strut (38), and the retainer plate (22) prevents the given strut (38) from engaging the other coupling plate (10), thereby eliminating the deleterious ratcheting contact between the given strut (38) and the other coupling plate (10).

Title: Adjustment of call selection to achieve target values for interval-based performance metrics in a call center
Inventor: ERTEL JAMES EDWARD
IPC: H04M3/00
Filed: 1999-11-04
Abstract: A call selection process in a call center is controlled so as to ensure the achievement of target values for one or more interval-based performance metrics. In an illustrative embodiment, a memory in the call center is used to store information regarding contractual target values of one or more interval-based performance metrics such as, for example, an average speed of answering metric, or a percent in service level metric. The call selection process is then adjusted within a given performance interval based at least in part on a comparison of a value of the metric actually achieved during the interval to the corresponding stored target value. For example, a service objective of the call selection process may be adjusted at one or more designated points in the interval if the value of the metric actually achieved to a given one of the points will not allow achievement of the target value within the interval.
Patent CA-2288542-A1 (CA)
Title: Floating ring mixer for extruder
Inventor: MYERS JEFFREY A
IPC: B29C48/67
Filed: 1999-11-04
Abstract: An extruder-mixer has a plurality of rotor rings provided on the downstream end of a motor driven extruder shaft mounted for rotation in a conventional heated barrel or stator. The rings comprise a plurality of spaced driven rotor rings spaced apart from each other and a plurality of non-driven but rotatable floating rings interleaved between each pair of driven rotor rings. Both rings have parallel upstream and downstream faces between which polymer flow passageways extend so that the polymer melt moves downstream first through one type of ring followed by movement through the other type of ring and the viscosity of the melt causes the rotatable floating rings to be rotated by the driven rings at a slower speed than the driven rings so that shearing force on the melt effects mixing of the melt.

Title: Tough-coated hard powders and sintered articles thereof
Inventor: TOTH RICHARD EDMUND
IPC: B22F1/18
Filed: 1998-05-13
Abstract: A sintered material and the tough-coated hard powder (TCHP) to make such a material is comprised of core particles that consist essentially of a first metal compound having the formula M aX b. M is a metal selected from the group consisting of titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, tungsten, aluminum, boron and silicon while X represents one ormore elements selected from the group consisting of nitrogen, carbon, boron and oxygen. The letters a and b represent numbers greater than zero up to and including four. The core particles are surrounded by an intermediate layer consisting essentially of a second metal compound, different in composition from the first metal compound thereby forming coated particles. The material of the intermediate layer has a higher relative fracture toughness than the material comprising the core particles and is capable of bonding with the metal compound(s) forming the core particles and also being capable of bonding with iron, cobalt or nickel. The coated particles are surrounded by an outer layer of iron, cobalt, nickel, their alloys, their mixtures and their intermetallic compounds. The intimate liaison of multiproperty alloys within the TCHP grains allows the combination of normally conflicting sintered article performance characteristics (e.g., strength and hardness) at levels heretofore unseen in the powder metallurgical art.

Title: Custom coupon process
Inventor: SHIRLEY TERRY JOE
IPC: G06Q30/00
Filed: 2000-04-25
Abstract: A unique process by which manufacturers and retailers are able to offer coupon savings utilizing the Internet or direct mail to customize and deliver unique customer selected coupon savings. In a retailer application, the consumer selections are delivered in one of two manners. If the retailer uses a "frequent shopper card," which is customer specific, formatted data is collected, maintained and transmitted to the retailers' secure interface. The data is then transmitted to the appropriate retailers' point-of-sale system. The consumer selected discounts are deducted from the consumer's grocery total after purchase verification and use of the "frequent shopper card." If a "frequent shopper card" is not used by the retailer, a database will collect the selection data, laser print the customer specific coupon selections, imprint each with the appropriate consumer identification and retailer logo, and direct mail the coupons to the consumer. In a completely non-Internet application, consumer selections are made, scanned and recorded using a paper selection form delivered through the mail. Regardless of method, all consumer selection data is catalogued, maintained and managed by the database.
