  • Patent number: 12270602
    Abstract: The invention relates to a method and an apparatus for preparing a cryogenic sample, whereby the sample is subjected to rapid cooling using a cryogen. A pair of conduits for transporting cryogenic fluid are provided, each of which conduits opens out into a mouthpiece, which mouthpieces are arranged to face each other across an intervening gap, wherein in the gap a sample that is provided on a substantially planar sample carrier can be received. Cryogenic fluid can be pumped through the conduits so as to concurrently flush from the mouthpieces and suddenly immerse the sample in cryogenic fluid from two opposite sides. As defined herein, at least one of the mouthpieces comprises at least two nozzle openings for evenly cooling the substantially planar sample carrier during the flushing.

  • Patent number: 11313069
    Abstract: A stain removal accessory that cooperates with a stain removal device for treating a stained area is attached to a front head of the stain removal device, namely to a water and/or steam venting face of the stain removal device. The stain removal accessory includes a container like a pad, a cartridge, a sachet, or a capsule provided with a permeable external layer, for containing a stain removing material, and a flap-flip piece including a holder for holding the container, whereby the stain removal accessory is adapted to release the stain removing material on the stained area when cooperating with the stain removal device by facing a flow of water and/or steam generated by the stain removal device.
