  • Patent number: 7870945
    Abstract: A method for sorting objects using a continuous loop conveyor sorting system having two or more feeders. In one embodiment, the method includes sorting a batch of objects to form a first group of objects and a second group of objects, using a first feeder to feed all of the objects from the first group onto the conveyor, using a second feeder to feed all of the objects from the second group onto the conveyor, removing the objects from the first group from the conveyor prior to the any of the objects reaching the point at which the second feeder feeds objects onto the conveyor, and removing the objects from the second group from the conveyor prior to the any of the objects reaching the point at which the first feeder feeds objects onto the conveyor.

  • Patent number: 6935522
    Abstract: Pre-packaging of flats mail by mailers, printers, and binding houses is provided by a carrier assembly that provides optimum shipping volumes while requiring reduced handling at postal facilities at elevated rates while supporting both manual and automated mail processing. The carrier assembly consists of a substantially rigid carrier body of rectangular cross section and includes a plurality, at least two, of generally flat, rectangular side walls and at least one end wall, two or more of which have one or a pair of banding guide slots formed in respective outer edges thereof in mutual registration for receiving banding or other strapping means in either parallel or cross-banding arrangements for securing mail loaded therein.

  • Patent number: 6685030
    Abstract: A method and system for collating groups of flats mail items for a plurality of carrier routes into carrier walk order sequence (CWS) using a Flats Bundle Collator (FBC) system which is capable of pre-staging carrier route subsets in one or more staging towers, or immediately collating a group into CWS for a group being fed into the system. The pre-staged subsets can be collated by the staging towers on demand. A U-shaped footprint for the FBC facilitates loading and unloading by the same operator. Additional input feeders may be added to the modular FBC, as well as random sequence towers.

  • Patent number: 6598748
    Abstract: A method and system for re-sequencing mail prepared in enhanced carrier route line of travel (ECR-LOT) format into carrier walk sequence (CWS) format within a flat bundle collator (FBC) system. The mail items in LOT are separated into subsets, one subset being in the same order as CWS, and another subset being in reverse order to CWS. All items from all groups are then merged into a stream of items in CWS for delivery by mail carriers.

  • Patent number: 5652149
    Abstract: An assay device for detecting the presence of analytes in an unknown sample includes a reaction system wherein resilient storage reservoirs containing reagents are fluidly connected to a track containing the sample. An actuation mechanism forces the reagent from each of the reservoirs into the track where the reagents mix together and with the sample. The mechanism produces a first flow rate and the mechanism is operable to reverse the pressure applied to the reservoirs to reverse the direction of flow of the fluids in the track for a predetermined period of time after which the flow is again reversed. The mechanism then reduces the force applied to allow a second flow rate less than the first flow rate so that reaction can occur whereby a determination may be made as to whether the target analyte is present in the sample.

An actuation mechanism forces the reagent from the reservoirs and into the track where it mixes the reagents together and then with the sample at a first flow rate. The mechanism then reduces the force on the reagent to allow a second flow rate less then the first flow rate to force the reagent and sample mixture through the track so that reaction can occur, whereby a determination as to whether the target analyte was present may be made.
