Abstract: A conveyor track drive includes a continuous loop conveyor for supporting and carrying a specimen container, with one portion of the conveyor extending through a drive housing. The conveyor includes a first segment extending through the housing, which then wraps around a portion of a drive sprocket, extends back upstream and around a portion of an idler sprocket and then includes a second segment transversely adjacent the first segment. A guide plate on the housing is positioned over the adjacent segments of the conveyor with a slot located to guide a specimen carrier from the first segment to the second segment. The specimen carrier then exits the housing on the second segment of the conveyor. A motor in the housing drives the drive sprocket to move the conveyor.

Abstract: A transfer apparatus includes a shuttle depending from an overhead support with a pair of arms for receiving and shifting a specimen carrier from one conveyor to a second conveyor of a dual-conveyor track. The shuttle is operable to retain a specimen carrier along either the first or second conveyor and to release a specimen carrier along either the first or second conveyor. Sensors are located to detect the presence of a specimen carrier at each of the retention locations, and to confirm the release of a specimen carrier from the shuttle along each of the conveyors. A drive motor for moving the shuttle between the retention and release positions is electrically connected to a command module with a processor, for receiving instructions as to the position of the shuttle. The sensors are also connected to the processor to transmit detection data to the processor. A queue is positioned upstream of the shuttle and is electrically connected to the processor.

Abstract: A transfer and positioning apparatus includes a positioning assembly located between the tracks of a dual lane conveyor and upstream of a lane changer. The positioning assembly includes a retractable shaft for stopping a carrier along a first conveyor adjacent the assembly. A pair of gripper arms are pivotally mounted to move between an open position permitting the carrier to pass along the conveyor track, and a closed position with forward ends in contact with a specimen container on the carrier to position the container in a reference location for direct processing. The lane changer includes a shuttle depending from an overhead support with a pair of arms for receiving and shifting a specimen carrier from one conveyor to a second conveyor of a dual-conveyor track. The shuttle is operable to retain a specimen carrier along either the first or second conveyor and to release a specimen carrier along either the first or second conveyor.

Abstract: A method and apparatus that collects demographics from contestants using ubiquitous Internet devices or a new slot machine on a casino floor. Contestants are given the opportunity to earn points that they can redeem for various prizes that are of interest to them. A plurality of prizes can be selected from a plurality of categories. As the contestants play games of chance, a pool of advertisements is presented to the contestants. Advertisements from the pool are selected in accordance with each contestants buying propensity. As contestants play games of chance, the system infers additional propensities of each user and stores this for later reduction. The reduced data is then sold as marketing data together with a list of system users that comprises name, address, phone number and e-mail addresses and the like. The system is implemented using a client-server paradigm. A server maintains databases needed to track all of the contestants that register with the system.

Abstract: A conveyor track drive includes a housing with a first continuous loop conveyor having a portion extending through the housing within a generally horizontal drive plane. The conveyor includes a first segment extending through the housing in the drive plane, then wraps around a portion of a drive sprocket, extends back upstream and around a portion of an idler sprocket and then includes a second segment transversely adjacent the first segment within the drive plane. A guide plate on the housing is positioned over the drive plane with a slot located to guide a specimen carrier from the first segment to the second segment at the point where the two segments are adjacent one another. A motor in the housing drives the drive sprocket to move the conveyor.

Abstract: The passive transfer guide of the present invention is positioned in a section of tangency between a first continuous loop conveyor and a second continuous loop conveyor, with a first guide lane for directing a specimen carrier from the first conveyor to the second conveyor, and a second guide lane for directing a specimen carrier from the second conveyor to the first conveyor. The guide includes a horizontally oriented “H”-shaped central member having a pair of upper legs, a pair of lower legs, and a cross-member connecting the upper and lower legs. The upper legs and an upper portion of the cross-member form one specimen carrier-directing lane, and the lower legs and a lower portion of the cross-member form the second carrier-directing lane.

Abstract: A scanning apparatus includes a pair of operable scanners which project scan beams along beam paths that reflect off of a back mirror. Each beam path has an initial portion prior to reflection off the back mirror, and a reflected portion after reflection. A passageway is created which crosses through both the initial and reflected portions of both beam paths such that the scan beams cover the entire perimeter side wall of the object.

Abstract: Compounds containing a cephem nucleus are prepared by heating a 1-oxide of a Schiff base of 6-aminopenicillanic acid. These cephem compounds are useful as intermediates in the preparation of physiologically active cephalosporins.
