摘要： The invention concerns a process for washing fibrous materials, skins, textile materials or the like using an aqueous, surfactant containing washing liquid obtained by adding washing agents to water. The minimal dispensed amounts as determined in subsequent washing tests are always obtained automatically, without the cleaning power and the cleaning efficiency being reduced to unacceptable levels. To this end, the surface tension of the washing liquid is measured during the washing process using a tensiometer. The actual washing agent concentration is derived from these measured values and an initial concentration is derived from the quantity of washing agent added. The detergency is calculated from this initial concentration. The addition of a washing agent is discontinued when no further increase occurs in the detergency. The invention also concerns a device for carrying out the process. The device has capillaries connected to constant gas flow sources and immersed to the same depth in the washing liquid. The capillaries are connected to a device for determining the pressure or the frequency of pressure variations which controls a dispensing unit via an evaluation unit.

摘要： The present disclosure refers to a gas fuel admission system for a gas fired engine. A gas pressure regulating unit includes a gas pressure regulating unit inlet and a gas pressure regulating unit outlet. The gas pressure regulating unit is configured to receive gas and to discharge the gas at an injection pressure. An engine gas inlet is configured to direct gas into the at least one combustion chamber. A gas admission valve is configured to admit the gas having an injection pressure at a predetermined time for a predetermined duration into the engine gas inlet. A gas pressure relief device is fluidly connected to the gas conduit and it is configured to relieve overpressure of the gas in the gas supply conduit, if a pressure differential between the injection gas pressure and the intake air pressure is above a predetermined threshold. A specific engine control module is configured to control the gas admission valve in response to inputs from various sensing devices.
