Abstract: A process for detecting link status in a computer network where the link and the load at the end of the link have a matched characteristic impedance. The data to be transmitted over the link is converted into a substantially continuous, random signal with a substantially known spectrum. This signal is transmitted over a link from a first end to the second or receiving end of the link. The first end of the link is analyzed for a reflection signal caused by a mismatch of the characteristic impedance of the link and the termination of the link. The link is identified as satisfactory if the reflection signal represents a substantial match between the characteristic impedance of the link and the characteristic impedance of the termination of the link. The link is identified as defective if the reflection signal represents a mismatch between the characteristic impedance of the link and the termination.
Abstract: The vehicle heater described has a burner supplied from a tank through a fuel line to which a pressure-controlled fuel pump (2) and a solenoid valve (24) are connected. The solenoid valve offers a relatively high resistance to the flow of fuel. The pressure in the pump delivery line thus drops relatively slowly. If vapor/gas forms in the fuel line (L2, L3, L4) due to overheating, it must be driven out of the line as rapidly as possible when the heater is switched on. The solenoid valve (24) offers only a low resistance to air/vapor/gas, resulting in a rapid drop in pressure at the pump delivery outlet and hence an increase in pump frequency (i.e. pump performance). The gas is therefore driven very rapidly out of the line between the pump and the burner, thus avoiding any interruptions in operations due to gas/vapor which has collected in the fuel line.

Abstract: The open cast mining apparatus comprises two sets of running gear between which a cutting drum is provided on a chassis. The conveyor tract is formed by an axial discharge conveyor inside the cutting drum, a vertical worm conveyor and a conveyor in the discharge jib or in the connecting bridge. The latter is supported on a loading carriage travelling parallel to a working face belt. The cutting drum is so designed that the mining machine can excavate and pick up material to be conveyed in both travelling directions.
Abstract: The present invention pertains to the problem of compressing biomass, e.g., ripe grain or cereals, into solid pressed bodies 1, which are suitable for use as fuel, despite differences in the harvesting conditions, and whose strength no longer depends on the moisture content in the biomass. It was found that this problem can be solved without an essential expense by imparting a wavy structure 6 to the pressed body 1. As a result, the outer surface of the pressed body 1 is compressed more strongly by the extrusion than is the middle cross section area, in which long-fibered parts of the mass are readily oriented in a wave shape 21 and lead to elasticity of the pressed bodies 1, which is favorable for handling.
