Title: Electrode for plasma generator the generator comprising same and process for treatment of solidifying liquid metal
Inventor: ROSEN RAN
IPC: H05H1/34
Filed: 1997-01-16
Abstract: A main electrode for plasma arc generator, a generator comprising same and a process for treatment of solidifying liquid metal by the mentioned generator, wherein the main electrode in association with a counter electrode provides a two-rail structure capable of generating a plasma arc discharge displaceable along a closed path uninterruptedly. The uninterrupted movement of the arc discharge is achieved by a specific design of the main electrode. The electrode comprises an essentially tubular body having a first rim usually connected to a d.c. power source via at least one connector site, and a second, working rim serving for the electric arc discharge. The tubular body is divided by at least one slot (gap) associated with one connector site and extending between the first and second rims so that it forms at the second rim region a second rim gap. Two sides of the second rim gap are an arc transmitting and an arc receiving zones, respectively. Mutual positions of these two zones and the associated connector site are such, that when the arc column is created and displaces along the second rim, it will always be transmitted from the transmitting zone to the receiving zone at a location positioned downstream from the projection of the associated connector site to the second rim (in respect of the direction of the plasma arc movement). Owing to this arrangement the arc column will cross the second rim gaps uninterruptedly.

Title: A self-configuring radio network
Inventor: MCGIBNEY GRANT
IPC: H04W40/00
Filed: 1999-07-09
Abstract: This invention is a radio terminal that co-ordinates with similar terminals around it to form a time division multiple access (TDMA) network. No base station or special devices are needed to manage the network. The terminals autonomously establish the critical functions that form the backbone of the network including routing anal synchronization. Once established, any terminal can send radio messages through the network using any modulation format, analogue or digital, that meets the network's bandwidth, timing, and power specifications. Terminals are able to reach destinations beyond their range by routing signals through neighbouring terminals. The routing algorithm is simplified considerably by exploiting the broadcast nature of radio waves and allowing the signal to take more than one path through the network at the same time. For network synchronization, each terminal acts as both a slave, locking its clock frequency to the rest of the network, and a master, pushing the network frequency to match its own reference. In a simplified embodiment of the invention, the terminal accesses the network but does not participate in routing or synchronization. This allows battery-powered devices such as handheld terminals to access the network.
