摘要： A leak detector operating according to the counterflow principle comprises a first high vacuum pump that operates in series with a primary pump. A second high vacuum pump is branched at a connecting point and an entry side thereof is connected to a mass spectrometer. A light test gas in the form of helium flows through the second high vacuum pump in a direction opposite to a transport direction. A conduit connecting an inlet to the entry side of the first high vacuum pump is devoid of restricted flow zones and valves in such a way that the pumping capacity of the leak detector is high for helium, thereby reducing the response time thereof. A valve for blocking the conduit leading via the first high vacuum pump is arranged between the exit side thereof and the entry side of the primary pump.

摘要： A leak detecting device of the counterflow type includes a high vacuum pump having an inlet connected to a mass spectrometer. In addition, a prevacuum pump is provided having an inlet connected to an outlet of the high vacuum pump and a leak detecting device input. A connecting conduit is further provided between the leak detecting device input and an intermediate inlet of the high vacuum pump. A first valve of variable conductance is arranged in the course of the connecting conduit. Valves with a large inner diameter are expensive while valves with a small inner diameter show considerable resistance even in a fully opened state. A second valve arranged parallel to the first adjustable valve is provided in the course of the connecting conduit; thereby allowing the first and second valves to have relatively small inner diameters arranged in the connecting conduit, wherein the combined conductance of both opened valves is considerably increased.

摘要： The invention relates to a process for operating a test gas leak indicator (1) with a gas inlet (2) and a test gas-sensitive detector (4), in which all or part of a stream of gas containing the test gas reaching the inlet (2) is taken to the detector (4) in the event of a leak; in order to improve the sensitivity of the leakage detection, it is proposed that the stream of gas be preferably periodically modulated and the signal from the test gas detector (4) be processed in synchronism with the modulation of the gas flow.

摘要： A counterflow leak-detector unit (1) with an inlet (2) connected to a test specimen, or a chamber housing a test specimen. A high-vacuum pump (4) produces pressure in a test-gas detector. The inlet (2) to the leak-detector unit is connected to an intermediate line (16) in the high-vacuum pump (4). To increase detection sensitivity without any danger of the pressure in the detector rising to inadmissible levels, a constriction (17) is located between two high-vacuum pump states (5, 6) of the high vacuum pump (4). Pump stages (5, 6) are separated by the intermediate line (16). The inlet (2) to the leak-detector unit (1) is connected to the outlet side of the high-vacuum pump state (5) at a point upstream of the constriction (17).

摘要： The invention relates to a sheathing laminate for an absorbent product, such as a sanitary napkin, a diaper, an incontinence protector or the like, and which is to be used as a liquid permeable top layer, which, when the product is in use, faces the body of the user. The laminate (30) comprises a web (10) of plastic film, to one side of which are fixed two mutually spaced, longitudinal strips (14, 16) of non-woven material, while to the other side of the plastic film web (10)--in an area between the two strips (14, 16) on the opposite side of the plastic film web--there is fixed a longitudinal intermediate strip (26) of non-woven material. When used on an absorbent product, the laminate has perforations (42) at least within a portion of the area of the intermediate non-woven strip (26). The invention also relates to a process for manufacture of the sheathing laminate.

摘要： A leak detector includes an inlet, a high-vacuum pump, and a test gas detector, which is connected to the entry of the high-vacuum pump. A backing pump is connected to an outlet area of the high-vacuum pump, and a test gas line extends between the inlet of the leak detector and the backing pump, the test gas line being connected to the outlet area of the high-vacuum pump via a line section. In order to shorten the response time of the leak detector, the line and the backing pump are connected via separate connections to the outlet area of the high-vacuum pump.
