    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 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 test apparatus includes a housing having an interior sized for retaining a plurality of instrument components including a control unit. A sniffer gun is linked to the instrument components, the sniffer gun having an intake point, and a test leak includes a gas reservoir, a constriction, an opening suited for introducing the intake point of said sniffer gun, and a temperature sensor. The temperature sensor is linked, either by means of a wired connection or wirelessly to the control unit for signal transfer.

    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.

    摘要： A process is disclosed for inspecting a plurality of similar test bodies for leaks. The test bodies are first evacuated by a fore-vacuum vacuum pump (evacuation mode), down to a pressure P.sub.u, selected to ensure that the maximum admissible pressure in the mass spectrometer (5) is not exceeded when the measurement mode is switched on, and then the evacuation mode is switched to a measurement mode by opening the second valve (16). In order to shorten evacuation times, a learning process is used to determine the optimum switching pressure P.sub.u opt.

    摘要： The invention concerns a gas leak detector (1) having an inlet (3) enabling connection to a test piece or test chamber, a detector unit disposed within the detector (4), a high-vacuum pump (5) which is connected at one end to the detector unit and through which a test gas, such as helium, passes in the opposite direction, a back-up pump (6), a line (9, 13) joining an outlet of the high-vacuum pump (5) with an inlet of the back-up pump (6), and a line (7, 9) joining the test-piece connector (3) to the high vacuum pump outlet. In order to reduce the complexity and expense necessary to produce the back-up vacuum, the invention proposes that line (13) is fitted with a throttle (14) and including a further line (15) which is fitted with a valve (16), said line directly joining the test piece (3) to the inlet of the back-up pump (6).
