Title: Methods and apparatus for route optimization in a communications system
Inventor: BUDKA KENNETH CARL
IPC: H04W36/12
Filed: 1999-10-26
Abstract: A route optimization technique in a GPRS network includes establishing a gateway GPRS support node in a visiting public land mobile network in which a roaming mobile station is currently located. Specifically, a tunnel is formed between the gateway GPRS support node and a serving GPRS support node to which the mobile station is in direct communication over a radio link. In this manner, external corresponding hosts may route packets to the gateway GPRS support node, rather than the GPRS  support node in the mobile station's home public mobile network, as is done in conventional GPRS networks. Advantageously, a shorter path is established for transfer of packets between a mobile station and a corresponding host. A similar route optimization technique is provided in a CDPD network, wherein a home mobile data-intermediate system node (local HMD-IS) in the foreign (visiting) network serves as a gateway node to the roaming mobile-end system.

Title: Nurse inductor apparatus for air seeders
Inventor: ENGEN RONALD NATHANIEL
IPC: A01C7/04
Filed: 1999-11-04
Abstract: A nurse inductor mechanism for an agricultural seeding implement converts an air seeder meter box into a nurse inductor box to convey seed particles to the singulator of a planting mechanism. The nurse inductor mechanism is detachably mounted on the meter box of the air seeder to receive a supply of seed particles therefrom. The nurse induction mechanism intercepts the normal air flow for the metering mechanism to divert the stream of air into engagement with a pile of seed particles and induce the entrainment of the seed particles for conveyance thereof to the remote planting mechanism. A partition wall divides the nurse induction mechanism into a seed side and an air side. The seed side receives the supply of seed particles from the hopper and allows the seed to pass through a passageway into the air side for engagement by the stream of air. Divider walls are provided to isolate each discharge tube from the other discharges tube so that the planter mechanisms can provide a continuous supply of seed particles. The discharge tubes pass through the nurse induction mechanism in a stacked pair, modular configuration with the respective discharge tubes being adequately separated with respect to the seed side to permit the passage of seed particles therebetween.

Title: The method for padding ground below a duct using excavated soil, device for realising the same, equipment for compacting soil below a duct and soil-compacting mechanism
Inventor: BYKOV ALEXANDR V
IPC: E02F5/10
Filed: 1998-06-26
Abstract: The present invention relates to a method for padding ground below a duct (1) using excavated soil (2), wherein said method uses a vehicle (6) that comprises a soil feeding organ (13), a transport organ (14) and soil compacting organs (104, 105). The vehicle moves along a ground path (16) which is formed by the soil feeding organ (13) as it collects excavated soil (2). This method allows for a reliable orientation of the soil compacting organs (104, 105) relative to the duct (1), wherein said compacting organs apply a force on the soil previously deposited in the trench (4). This invention also relates to a device which is used for padding ground below a duct (1) and comprises a device (106) for hanging a soil-compacting mechanism (103) to the vehicle (6). The device (106) includes a disconnection mechanism (153) that enables the cyclic displacement of the rammer-type compacting organs (104, 105) in the displacement direction of the vehicle (6). When compacting soil, the working members (171) of the compacting organs (104, 105) are capable of cyclic downward displacement towards each other while simultaneously rotating in a direction in which the angle they define becomes smaller. This system may be used for efficiently compacting soil below a duct (1) while minimising the stress applied by the soil to the surface of said duct (1).
