    • The invention relates to a malodor reducing composition comprising: at least one of (A) phenylglycidate represented by the following formula (1): wherein R1 is a C1-C4 branched or linear alkyl group, R2 is hydrogen or methyl, and R3 is hydrogen, a C1-C4 branched or linear alkyl group or a methoxyl group; and (B) 1,2-diketone represented by the following formula (2) or (3): wherein R4, R5 and R7 are each independently, a C1-C5 linear or branched alkyl or alkenyl group, R6 is a (C1-C5) alkylidene, R4 and R5 may form a C4-C7 saturated or unsaturated alicyclic or hetrocyclic ring structure which may be mono-substituted or poly-substituted by (C1-C4) alkyl groups, and R6 and R7 may form a C4-C7 unsaturated, alicyclic or heterocyclic ring structure which may be mono-substituted or poly-substituted by (C1-C4) alkyl groups; and the weight ratio of the phenylglycidate (A) to the 1,2-diketone (B) being from 1:99 to 99:1. The invention also relates to the fragrance composition and consumer products containing this malodor reducing composition.

    • A method and apparatus for measuring the flow rate of a single phase fluid, particularly a gas, through a conduit. A pulse of tracer fluid is discharged or injected into a first fluid flowing through a conduit, the concentration of the tracer fluid is measured as a function of time at a downstream from where it is injected, and the flow rate of the first fluid is determined based on the concentration measurements. The concentration of tracer fluid is preferably sampled substantially continuously from when the tracer gas first passes the measuring point until substantially all of the tracer fluid has passed the measuring point and the sampled concentrations integrated. The concentration of tracer fluid is preferably determined by measuring the thermal conductivity of the mixture of the first fluid and tracer fluid which is dependent upon the concentration of the tracer fluid.
    • 一种用于通过导管测量单相流体,特别是气体的流量的方法和装置。 示踪液的脉冲被排出或注入到流过导管的第一流体中,示踪流体的浓度作为时间的函数在其被注入的下游被测量,并且确定第一流体的流量 基于浓度测量。 从示踪气体首先通过测量点直到基本上所有的示踪流体已经通过测量点并且采样的浓度整合时,示踪剂流体的浓度优选基本上连续地取样。 示踪剂流体的浓度优选通过测量依赖于示踪流体浓度的第一流体和示踪流体的混合物的热导率来确定。
