Title: Method and apparatus for a mail processing system
Inventor: BAKER CHRISTOPHER A
IPC: G07B17/00
Filed: 1990-10-16
Abstract: Mail handling or processing systems are disclosed wherein the entire lot or batch of mail pieces is loaded into a bin for processing. Each mail piece is individually removed by an operator while the computer monitors the weight of the bin and simultaneously produces serial numbers for affixing to each mail piece. In an alternative embodiment a postage meter provides postage imprinting and labelling for each mail piece removed. By monitoring the tare weight difference of the bin prior to and after removal of each mail piece, the mail piece weight is determined from the difference between the two tare weights. The weight of each mail piece is required in order to determine postage cost or mail charges for each mail piece.      After all pieces of mail are removed from the bin, an operator can optionally key the system to produce a postal service form complying with manifest mailing requirements.      The computer also produces a manifest including serial numbers and mail charges related to each serial number marked mail piece and a manifest summary.      In an alternate embodiment, the bin is loaded one by one with each mail piece while a computer simultaneously monitors the weight of the bin as each mail piece is added, serial numbers are produced for affixing to each mail piece, and the computer links each serial number with a weight deviation thereby calculating mail charges for each mail piece and storing the information for reproduction in summary form in a mailing manifest.

Abstract: HARVESTING MACHINE      Abstract A harvesting machine is especially adapted for automatic topping and loading of crops, such as onions. The crops are gathered from the field and elevated on a conveyor to a region adjacent to which a topping device (a sickle) is disposed.  The conveyor has openings to permit the passage of air which is blown from a blower. The openings are sufficiently narrow to support the crop while allowing rocks, clumps and other debris to drop therethrough. The blower is offset from the topping region.  A duct extends tangentially and upwardly from the blower to direct a laminar (non-turbulent) flow of air through the conveyor openings for extending the tops.  The duct has a wall at the bottom thereof which faces the region. This wall has a passage, preferably with louvers which extend generally vertically.  A negative pressure is developed adjacent to these louvers and a generally laminar flow of air passes upwardly through the louvers and enhances the laminar flow through the conveyor in the region where topping occurs.  The rocks, clumps and other debris fall downwardly through the louvers and out of the machine thereby preventing damage to the blower.

Patent CA-2076781-A1 (CA)
Inventor: RUBSCHA ROBERT F
IPC: B65H29/58
Filed: 1992-08-25
Abstract: ABSTRACT         A printer capable of producing simplex and duplex copies includes a tri-roller inverter that employs a passive deflector gate downstream from input and output nips of the tri-roller inverter. A sheet driven by the input nip into a reversing chute of the inverter deflects the passive deflector gate to an open position that allows the sheet to enter the inversion chute and after the sheet is past the gate it returns to close deposition, thus allowing the sheet to be driven past it in reverse by a reversing roller. Once the lead edge of the reversed sheet passes the passive deflector gate, a second sheet enters the input nip resulting in two sheets being in the inverter at the same time.
