  • Publication number: 20250009925
    Abstract: A diffuser device disperses a substance that is in a liquid or a solid state at room temperature into the air as a vapor. The diffuser device has a receptacle that holds a storage container containing the substance. A porous body has an evaporation surface located in the receptacle. A heating member is arranged on or in the porous body so as to control a flow of the substance through the porous body. An aeration system has an air inlet, a fan and an air outlet. The aeration system is configured to create a flow of air from the air inlet to the air outlet while sweeping across the evaporation surface in an upward direction with respect to the diffuser device.

  • Patent number: 10548867
    Abstract: The invention relates to novel soothing compositions for animals, particularly for cats. It specifically relates to soothing compositions for non-human mammals, comprising between 1% and 50% w/w of at least one fatty acid comprising between 5 and 22 carbon atoms and between 0.01% and 5% w/w of nepetalactone, such that said at least one fatty acid and said nepetalactone are dissolved in a solvent. Said compositions are characterised in that they exhibit soothing properties for stressed animals and are stable for the entire period of use thereof.

  • Patent number: 10517292
    Abstract: The invention relates to paintball-pellet-type projectiles containing insect pheromones encapsulated in an aqueous oil-in-water-type formulation. Said formulations can release said pheromones in a sustained manner. Said projectiles are characterised in that they contain the aqueous formulation of encapsulated pheromone compatible with the envelope of the projectile composed of oxo-degradable polymer. The aim of the invention is to use said projectiles to treat trees against insect pests by spraying and bursting said projectiles on the trunks of said trees.

  • Patent number: 10271547
    Abstract: The present invention is directed towards microparticles consisting of a solid shell made of polymer, in particular an acrylic polymer, surrounding a core comprising a mixture of oil and wax and also pheromone. The present invention is also directed towards a production process and the use of an aqueous suspension of such microparticles containing pheromones comprising fatty chains, such as lepidopteran pheromones, and which are capable of releasing the pheromones in a sustained manner.

  • Patent number: 9866248
    Abstract: A method for verifying location information of a terminal equipped with a UICC card, connected to a cellular telecommunications network and located in a current cell, said terminal storing in the UICC card an identifier of the current cell and at least one identifier of a previous cell in which the terminal was previously located. This method comprises the following steps, implemented by a processing server connected to the network: receiving said identifiers coming from the terminal via the communication network; determining first location information using the identifier of the current cell; estimating second location information using the identifier of at least one previous cell; detecting a location error if the two items of location information correspond to different geographical positions according to a defined criterion.

  • Patent number: 9790171
    Abstract: The subject matter of the present invention is the novel molecules of formulae E, E? and F. These molecules prove to be synthesis intermediates that are very advantageous for the manufacture of derivatives of sphingosine or of ceramides functionalized in position 1, with good yields, in which R1 and R2 are fatty chains, R3 is an alkyl group and R4 is a protective group for alcohol functions. Another subject of the invention is the use of the intermediates of type F for converting same into intermediates of type G, by means of reduction in the presence of lithium borohydride. The G molecules are precursors that are known to make it possible to obtain sphingolipids or sphingomyelin.
