Abstract: A method and a regulating valve for maintaining a fluid pressure within a defined volume (3), and simultaneous registering of discharge of fluid from the volume as a result of leakage or consumption. The fluid is supplied from a pressure regulating valve (20) provided with a means (5-7, 22-26) which opens for the supply of fluid to the volume (3) when the pressure therein has sunk below a first value (P1), and which shuts off the fluid supply when the pressure in the volume (3) has achieved a preset second value (P2) which is substantially higher than the first value (P1). Thus, after each opening of the regulating valve (20) there occurs a distinct pressure increase at the valve outlet. This pressure increase is registered as a pressure pulse, and the frequency of delivered pressure pulses is monitored and utilised as a measure of occurring leakage and/or consumption of the supplied fluid.

Abstract: The invention relates to the characterising, separating and/or elimination of suspended particles in a carrier gas of an aerosol. According to a first aspect of the invention volatile suspended particles are eliminated in that in a first step the aerosol is heated to a temperature at which the volatile suspended particles evaporate and in a second step the aerosol is diluted with a dilution gas. The sequence of the first and of the second step may be exchanged. According to a second aspect a dilution of the raw gas takes place such that raw gas is led to a measurement gas channel through which measurement gas flows, wherein the quantity of raw gas transferred per unit of time is dependent on the volume flow in the raw gas channel. According to a third aspect of the invention, in a condensation nucleus counter not only is the number of scatter light pulses evaluated but also their intensity in order to be able to draw conclusions on the reliability of the measurement.

Abstract: The present invention, generally speaking, provides a firewall that achieves maximum network security and maximum user convenience. The firewall employs “envoys” that exhibit the security robustness of prior-art proxies and the transparency and ease-of-use of prior-art packet filters, combining the best of both worlds. No traffic can pass through the firewall unless the firewall has established an envoy for that traffic. Both connection-oriented (e.g., TCP) and connectionless (e.g., UDP-based) services may be handled using envoys. Establishment of an envoy may be subjected to a myriad of tests to “qualify” the user, the requested communication, or both. Therefore, a high level of security may be achieved. The usual added burden of prior-art proxy systems is avoided in such a way as to achieve full transparency—the user can use standard applications and need not even know of the existence of the firewall.
