  • Publication number: 20200337962
    Abstract: The present disclosure concerns a perfuming ingredient of a compound of formula (I) in the form of any one of its stereoisomers or a mixture thereof, and wherein X represents a CHO group when R1 represents a C1-2 alkyl group or X represents a CH(R6)CHO group when R1 represents a hydrogen atom or a C1-2 alkyl group. Each of R2, R3, R4, R5 and R6 represents, independently from each other, a hydrogen atom or a C1-2 alkyl group; or R3 and R4 represent, when taken together, a ethanediyl group; and —C(R3)(R4)—CH(R5)—OH group is, relative to position 1, an ortho, a meta, a para substituent of the aromatic ring or a mixture thereof. Also disclosed is the compound of formula (I) as part of a perfuming composition or of a perfumed consumer product.

  • Publication number: 20200319053
    Abstract: A leak detector for checking the sealing tightness of an object to be tested includes a detection inlet to be connected to the object, a first pumping device, and a gas detector. The first pumping device includes a first rough vacuum pump, at least one second rough vacuum pump, and a turbomolecular pump. The gas detector is connected to the turbomolecular pump. The outlet of the at least one second rough vacuum pump is connected to the first rough vacuum pump, between two in-series pumping stages of the first rough vacuum pump.

  • Publication number: 20200200641
    Abstract: A leak detector is provided for leak-testing objects that are to be tested by spraying tracer gas, the leak detector including: a detection inlet configured to be connected to an object that is to be tested; a pumping device including a vacuum line connected to the detection inlet, a rough-vacuum pump connected to the vacuum line, and a turbomolecular vacuum pump connected to the vacuum line, a delivery of which is connected to the rough-vacuum pump; and a gas detector connected to the turbomolecular vacuum pump, the pumping device further including an ancillary pump connected to the rough-vacuum pump and being configured to lower an ultimate-vacuum pressure of tracer gas in the rough-vacuum pump. A leak detection method for leak-testing objects that are to be tested by spraying tracer gas is also provided.
