A plasma torch comprises a cascade between a cathode and an anode. The cascade is an inter-electrode insert.

As a result of the cascade being provided, the output power of the plasma torch is obtained not by an increase in the electric current but by an increase in the arc electric voltage. Therefore, the lifespan of each of the electrodes, i.e., the cathode and the anode, becomes remarkably longer. In addition, since a quasi laminar flow of the plasma is generated in the interior of the cascade, a fluctuation in the output power of the plasma jet is reduced. Thus, it is possible to lower the driving and operating costs. Therefore, it is possible to perform surface treatment such as plasma spraying, utilizing a high-performance plasma processing, a processing of refractory powder materials, and plasma chemistry processing and the like, with a high degree of efficiency.

Method for transmitting packets in a network
Stream Control Transmission Protocol (SCTP) transmits packets to the remote peer with a size equal or smaller than Maximum Transmission Unit (MTU). The MTU can be discovered by SCTP utilizing the path-MTU discovery algorithm of RFC1191 (or similar techniques). However the MTU of a certain path within a SCTP association can change over time. If the path MTU grows then there is no problem. If the path MTU decreases, then packets with size equal to the old path MTU will not be able to be delivered to the remote peer as the link or router with the smaller MTU will drop the packet. Thus all such packets will remain unacknowledged and will lead to head of line blocking for in-sequence delivery of packets of the streams to which to non-delivered packets belong. This leads to the failure of the association. The proposed method resegments SCTP-packets due to a path MTU decrease in a SCTP association. |

Supporting measurments and feedback for 3D MIMO with data transmission optimization
Technology is discussed for supporting wireless communication paths from an antenna array with a vertical directional component. Examples reduce training feedback for increased numbers of communication paths by only reporting on a subset of Reference Signals (RSs) provided for various vertical beam configurations. Additional examples reduce feedback with virtual measurements based on a difference between RS measurements. One such measurement can come from full set of RSs for a reference beam configuration and another from a partial set of RSs for an additional beam configuration. Such virtual measurements can also be based on cross correlation for beamforming weights associated with the two configurations. Several examples of preparing and sending measurement reports consistent with Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) standards are discussed. The supporting technology also increases diversity and reduces a power differential between spatially multiplexed layers transmitting a common codeword. |
