Abstract: A control method for an electric power transmission line based network including network sections each having a monitor and at least one device group, each device group having at least one input device and at least one output device, each input or output device having a set switch comprising transmitting a packet from one device to another device of the same device group over the network section containing the device group wherein the set switch of the device may set itself to belong to one device group, all devices have a right of controlling the network with different priorities, the packet transmission is performed after the device transmitting the packet having controlled the network if the priority thereof is the highest among the activated devices, and the remaining devices in the same network section may read the packet.

Abstract: An electric power transmission system for communications includes on/off switches; high-voltage power assemblies; groups of high-voltage devices each being powered by the high-voltage power assembly; a carrier waves communications network comprising a transformer and filter, a filter, and a carrier waves coupling device interconnecting the transformer and filter and the filter, wherein the transformer and filter includes a low-voltage power assembly for communications and the filter includes a high-voltage power assembly for communications; and low and high-voltage devices. Data can be communicated between the low-voltage devices, between the high-voltage devices, or between the low-voltage device and the high-voltage device by transmitting carrier waves over the AC power.

Abstract: A fixture for testing the strength of a resistance spot weld connecting two test strips comprises two identical clamping frames, each having releasable clamps for gripping and holding one of the test strips. A pull bar is mounted on each clamping frame in any one of several selected angular positions. The pull bars are aligned with one another and then grasped by a pulling mechanism to apply a separating force on the two strips. The arrangement is such that the line of the separating force passes through the weld.
