  • Patent number: 9222777
    Abstract: A method and system for generating a location identification grid and for using a location identification grid. The location identification grid can include a first geographic area that correspond to a pre-existing area. This pre-existing area can correspond to a postal code such as a zip code, a telephone code such as, an area code, or any other desired pre-existing area. The location identification grid can be subdivided into smaller geographic areas to allow more accurate identification of a location. The location identification grid can include a second geographic area. The second geographic area can be a subdivision of the first geographic area. The location identification grid can be used with signals that identify a location within a location identification grid. These signals can include a first component corresponding to the first geographic area and the second component corresponding to one or more second geographic areas.

  • Patent number: 6227378
    Abstract: A sorting system is disclosed, for example for mail items. In the disclosed system, a circulating storage system can receive items from an inlet, and deposit them in an appropriate output receptacle which has been allocated to items in a particular group. For example, the items can be sorted by destination, and each output receptacle can be allocated to a particular destination. In the event that the destination of an item has not output receptacle allocated thereto, the system controller can determine whether to allocate a receptacle, or whether to recirculate the item within the circulating storage system. This possibility allows items to be grouped together within the system, until there are sufficient items for a particular destination to allow them to be handled efficiently, and in particular allows the allocation of output receptacles to destinations to be controlled efficiently.

  • Patent number: 5998752
    Abstract: There is disclosed a sorting system, relying on the identification of items to be sorted by means of codes applied thereto, in which it is possible to infer the identity of items whose codes have become unreadable. The system relies on identifying the item by reference to the codes of items which precede and which follow the item.

  • Patent number: 5054602
    Abstract: A sorting system comprises a number of sorting conveyors (1, 2 --- 12) each being capable of selectively discharging items fed onto the conveyor at an input thereto, from any one of a number of destination outlets and a plurality of aggregating conveyors (21, 22 --- 29) corresponding in number to that of the outlets of each sorting conveyor and extending transversely of the sorting conveyors, each aggregating conveyor being capable of receiving items from the respective sorting conveyors at a corresponding outlet in each case and of feeding the received items towards an output.

  • Patent number: 5010998
    Abstract: A diverter for diverting articles travelling on a conveyor, comprises a diverter member (1) which is mounted on a linkage for movement into and out of the path of the articles and which has an elongate article contact surface to cooperate with the articles travelling on the conveyor. The linkage includes a pivotal connection (4a) with the diverter member (1) intermediate the length of the surface so that the diverter member (1) on contact with each article gives the article a sustained push to guide the article laterally of the conveying direction followed by a final nudge to complete the lateral displacement.

  • Patent number: 4967857
    Abstract: A weighing arrangement comprises a conveyor system defining a path for articles and including a first feed conveyor, a second upwardly inclined conveyor arranged to receive articles from the first conveyor and a third, downwardly inclined conveyor. The first and second conveyors have respective first and second motors for independent drive.The weighing apparatus has a weight measuring component in the form of a rotatable cylinder which cooperates with load sensing means.In use, an article is fed from the conveyor to the cylinder of the weighing apparatus. Operation of the weighing apparatus is based on the principle that as the article changes direction to be discharged via the downward conveyor there is an instant at which the total mass of the article passes through its center of gravity so as to act directly downwardly via the cylinder on the load sensing means.

  • Patent number: 4873662
    Abstract: Informaton for display at a terminal apparatus of a computer is stored in blocks the first part of which contains the information which is actually displayed at the terminal and the second part of which contains information relating to the display and which may be used to influence the display at the time or in response to a keyboard entry signal. For example, the second part of the block could include information for providing the complete address of an another block which would be selected by the operation of a selected key of the keyboard. The second part of the block could alternatively influence the format and/or color of the display at the terminal. When a block is read from the store of the computer the second part is retained in another store which may be located in the terminal or in the computer itself or perhaps both. The invention is particularly useful in reducing the complexity of the operating protocol of the computer.

  • Patent number: 4497536
    Abstract: A technique for aligning and coupling dielectric optical waveguides comprises threading the end of a waveguide through the central opening of a triad ball connector and forming by fusion a generally spherical glass bead on the end of the waveguide using, for example, an electric arc. The waveguide is then drawn back so that the bead contacts the balls of the triad connector to accurately locate the waveguide. The bead acts as a locating element and also has beneficial focussing properties.
