Patent number: 6186335Abstract: A improved process for beneficiating kaolin clays to remove discoloring impurities is disclosed. The beneficiation of kaolin clay is improved by fractionating a kaolin clay starting material into a lower brightness first fraction having a majority of the discoloring impurities and a higher brightness second fraction with less impurities. The first fraction is then beneficiated (such as by flotation, selection flocculation, high intensity magnetic separation and/or leaching) to produce a kaolin clay product with improved optical properties. The first and second fractions may be combined to produce a product with improved optical properties.Type: GrantFiled: March 20, 1998Date of Patent: February 13, 2001Assignee: Thiele Kaolin CompanyInventors: Lee Ann Arrington-Webb, Robert A.

Patent number: 6178789Abstract: A convertible cylinder lock handle comprises a hub, a handle extending from the hub, and a drive shaft extending from the hub along an axis of handle rotation. The hub has a channel sized to receive a lock cylinder and a slot that extends along and spacially communicates with the channel sized to receive a spring loaded lock cylinder bolt. The lock handle also has a bolt lock plate sized to be received in reversible orientations within the slot that has two stops spaced apart a distance to receive and entrap the cylinder bolt therebetween. One of the stops has a ramp for camming engagement with the spring loaded cylinder bolt whereby in one lock plate orientation the bolt is locked out of the lock plate and in its reversed orientation the lock plate receives and entraps the bolt. The handle is particularly suited for use on delivery van type vehicles as it is fully compatible with existing lock cylinders that may be removed with spanner tools without having to disassemble the handle.Type: GrantFiled: March 30, 1999Date of Patent: January 30, 2001Assignee: Kason Industries, Inc.Inventors: Burl Finkelstein, Stevie C.

Patent number: 6152673Abstract: A front loading refuse collection vehicle (10) is provided having a body (12) which includes a hopper (16), a storage container (17), a pair of arms (56) coupled to a pivotal fork (58). The vehicle also has a control circuit (100) which coordinates movement of the fork with the arms. The control circuit receives the initial pickup position of the arms and fork from an arm position sensor (200) and a fork position sensor (201) when grasping a portable container. This position is later recalled to assist the operator in returning the arms and forks to these positions in order to release the portable container.Type: GrantFiled: September 23, 1997Date of Patent: November 28, 2000Assignee: Toccoa Metal Technologies, Inc.Inventors: James M.

Patent number: 6136801Abstract: Quantitative compliance markers and associated methods for monitoring patient compliance with medication prescriptions associated with compliance markers have been found to eliminate the need for specific quantitative relationships for each new drug tested. Such compliance markers and methods for monitoring patient compliance utilize pharmacologically inert substances, namely the weak acids benzodiazepines, or non-metabolizable substances in association with an underlying drug at a measurable dosage, so as to correlate compliance marker concentration with underlying medication concentration to determine amount of actual medication ingested.Type: GrantFiled: December 24, 1998Date of Patent: October 24, 2000Assignee: U. D. Testing, Inc.Inventor: Michael Kell

Patent number: 6135669Abstract: A cylindrical shape with a open channel running the entire length (7). Opposite of the channel is a rib (5) added for strength and rigidity of the connector. Four openings (1) with a 45 degree angle (2) used for clearance open to four slots (3). Each slot is in line with another forming two groups which allow a flattened end of a rod to be inserted, lowered, and snapped in place. Inserting a rod into both groups creates a simple, economical, and reusable connection. Four tabs (4) protrude into the channel with a center line just above the top of the rod to be inserted allowing the rod to be held firmly in the connector and creating a barrier that doesn't permit the rod to start moving perpendicular to the connector which is how the rod is inserted and taken out. The length and width (6) of the material can vary depending on the weight requirements. A coated or inherently corrosion resistant alloy or a plastic that can resist the eliminates of the outdoors is appropriate.Type: GrantFiled: August 31, 1998Date of Patent: October 24, 2000Inventors: Mark D. Doelling, Michael C. Sacher
