  • Method for encoding and transporting database objects over bandwidth constrained networks
    Patent number: 6230165
    Abstract: A method of transferring information across a computer network with a server and a client. The information is divided into a plurality of cards and a plurality of card forms. Each card includes a plurality of values. Each card form corresponds to one of the cards and includes a description of the values of a corresponding card. The cards and the card forms are stored in a server data base on the server and a client data base on the client. The information in the server is changed or replaced by attaching a card delta to one of the cards. The card delta indicates which information in the respective card is to be replaced. The card deltas are transferred between the client data base and the server data base when data bases are to be updated.

  • Milling roller module for a surface miner
    Patent number: 6224163
    Abstract: A milling roller module for a surface miner, includes a milling roller operating with undershot for loosening the material from the block being mined, a support frame for fastening the milling roller to the surface miner, and a takeup chute for supporting the intermediate conveying of the loosened material in the area of the milling roller and for transferring the material to the downstream discharge belt in a specific manner. The drives are placed into the milling roller and the feed lines are led into the milling roller together with the support frame for fastening the milling roller from the side in the upper third of the milling roller diameter. As a result, it is possible to perform mining operations up to a cutting depth that is equal to half the roller diameter. A takeup chute is provided to transfer the material from the milling roller onto the downstream discharge belt in a specific manner.
