For leak testing closed containers (9) which are filled with a filling product containing at least one liquid component the container is introduced in a test cavity (1) which is evacuated at least down to vapour pressure of that liquid component. The pressure in the surrounding of the container (9)

For leak testing closed containers (9) which are filled with a filling product containing at least one liquid component the container is introduced in a test cavity (1) which is evacuated at least down to vapour pressure of that liquid component. The pressure in the surrounding of the container (9) and thus within test cavity (1) is monitored. Monitoring is performed by a vacuum pressure sensor (7), whereas lowering pressure surrounding the container (9) is performed by a vacuum pump (5). Leakage is detected by monitoring a pressure change in the surrounding of the container which is due to evaporation of liquid emerging from a leak and being evaporated in the low pressure surrounding.

The hanger comprises a resilient material with a flat base affixed to the wall with two forked tongues extend perpendicularly therefrom. The forked tongues engage the protrusions within the hollow channel to hold the frame member securely to the hanger and thus to the wall. The hanger with its resilient forked tongues assures proper spacing between the adjacent fabric wall panels mounted on the hanger. 810500, Gorewitz, 047/026; US-4280314, 19810700, Stuck, 053/241; US-4297811, 19811100, Weder, 047/072; US-4333267, 19820600, Witte, 047/084; US-4347686, 19820900, Wood, 047/073; US-4380564, 19830400, Cancio et al., 428/167; US-4400910, 19830800, Koudstall et al., 047/084; US-4413725, 19831100, Bruno et al., 206/045.33; US-D279279, 19850600, Wagner, D11/143; US-4546875, 19851000, Zweber, 206/082; US-4621733, 19861100, Harris, 206/423; US-4640079, 19870200, Stuck, 053/390; US-4717262, 19880100, Roen et al., 383/120; US-4733521, 19880300, Weder et al., 053/580; US-4765464, 19880800, Ristvedt, 206/082; US-4771573, 19880900, Stengel, 047/067; US-4773182, 19880900, Weder et al., 047/072; US-4801014, 19890100, Meadows, 206/423; US-4810109, 19890300, Castel, 383/105; US-4835834, 19890600, Weder, 029/525; US-D301991, 19890700, Van Sant, D11/149; US-4941572, 19900700, Harris, 206/423; US-4946290, 19900800, Matyja, 383/010; US-4980209, 19901200, Hill, 428/034.1; US-4989396, 19910200, Weder et al., 053/397; US-D315700, 19910300, Stephens, D11/151; US-5073161, 19911200, Weder et al., 493/154; US-5074675, 19911200, Osgood, 383/122; US-5105599, 19920400, Weder, 053/399; US-5111638, 19920500, Weder, 053/397; US-5120382, 19920600, Weder, 156/212; US-5152100, 19921000, Weder et al., 047/072; US-5181364, 19930100, Weder, 053/397; US-D335105, 19930400, Ottenwalder et al., D11/164; US-5199242, 19930400, Weder et al., 053/397; US-5205108, 19930400, Weder et al., 053/397; US-5228234, 19930700, de Klerk et al., 047/041.01; US-5235782, 19930800, Landau, 047/072; US-5239775, 19930800, Landau, 047/072; US-5249407, 19931000, Stuck, 053/399; US-5259106, 19931100, Weder et al., 029/469.5; US-5307606, 19940500, Weder, 053/410; US-5315785, 19940500, Avot et al., 047/072; US-5350240, 19940900, Billman et al., 383/104; US-5353575, 19941000, Stepanek, 053/461; US-5361482, 19941100, Weder et al., 029/469; US-5388695, 19950200, Gilbert, 206/423; US-5428939, 19950700, Weder et al., 053/397; US-5443670, 19950800, Landau, 156/191; US-5493809, 19960200, Weder et al., 047/072; US-D368025, 19960300, Sekerak et al., D09/305; US-5496251, 19960300, Cheng, 493/224; US-5496252, 19960300, Gilbert, 493/224; US-5526932, 19960600, Weder, 206/423; US-5551570, 19960900, Shaffer et al., 206/575; US-5572849, 19961100, Weder et al., 053/399; US-5572851, 19961100, Weder, 053/399; US-5617703, 19970400, Weder, 053/413; US-5624320, 19970400, Martinez, 472/051; US-5625979, 19970500, Weder; US-5647168, 19970700, Gilbert, 047/072; US-5647193, 19970700, Weder et al., 053/465; US-5715944, 19980200, Windisch, 206/423; US-D404684, 19990100, Shea, D11/164; US-5974730, 19991100, Chien, 047/041.01; US-D419436, 20000100, Celtorius et al., D09/305; US-6098336, 20000800, Ferguson, 206/423; US-6125578, 20001000, Weder, 047/072; US-6129208, 20001000, Ferguson, 206/423; US-6129209, 20001000, Tchira, 206/423; US-6279264, 20010800, Weder, 047/072
