摘要： The invention relates to a filtering device which includes a common-mode inductor (LF) comprising a winding (L1, L2) on each line of an AC power supply and a magnetic core made up of a first torus (T1) and a second torus (T2). The first torus (T1) has a first magnetic permeability (μ1) and the second torus (T2) has a second magnetic permeability (μ2, μ′2), the first permeability being equal to or greater than three times the second permeability, in order to prevent the common-mode inductor from saturating in the resonant frequency range of the filtering device. Application to the EMC filter of a speed variator.

摘要： This invention relates to methods of formulating steroid pheromones as novel stable emulsions. These emulsions can be used for administration of the steroid pheromones to living organisms such as humans or pigs in place of current organic solvent or pressurized aerosol formulations that present hazards in both shipping and application. Uses relating to pigs are in stimulation of sexual maturation, diagnosis of the onset and timing of oestrus in female pigs, and inducing boars to accept dummy sows. The water-based emulsions can include 5α-androst-16-en-3-one and 3α-hydroxy-5α-androst-16-ene for administration to pigs. The use of water-based emulsions eliminates the need for formulation of the steroid pheromones in organic solvents, delivery of these pheromones as pressurized aerosols, and following the precautions required to reduce hazards during shipping and handling. The water-based emulsions allow for treatment of living organisms where a liquid organic solvent formulation or aerosol of the pheromones might be harmful to the organism or a substrate.

摘要： A power switching circuit (T115, T5) including at least one bipolar transistor stage (T5) and a control circuit for that stage, the control circuit including first bias means for applying forward bias to that stage during first time intervals (t3), and second bias means for applying reverse bias to that stage during second time intervals (t2, t4), the reverse bias being intended to prevent charge accumulating in the transistor while it is subjected to a reverse voltage. The first bias means comprise a first capacitor (C108) and a first switching circuit (D120, T113) serving, outside the first time intervals, for selectively charging the first capacitor by means of a DC voltage soruce, and for discharging the first capacitor into a control input (T115-G) of that stage; and the second bias means comprise a second capacitor (C107) and a second switching circuit (D119, D123, T113, T114) serving, outside the second time intervals, for selectively charging the second capacitor from the voltage supply, and for discharging the second capacitor into the control input.
