  • Patent number: 12318059
    Abstract: A closure device for closing a particle capture volume, in particular a bag or a container, including an access element with an access element opening for providing an access to the particle capture volume, a closure slide which can be selectively displaced relative to the access element into a release position or into a closure position. In the release position the closure slide releases the access element opening and in the closure position closes the access element opening, and a locking mechanism for locking the closure slide in the closure position with respect to the access element, where the locking mechanism 6 for unlocking requires a defined unlocking element which is separate from the locking mechanism.

  • Patent number: 12167824
    Abstract: A particle receiving device for attachment to a particle outlet of a vacuum cleaner and/or of a cyclone separator and for receiving separated particles, including: a particle receiving volume for receiving the particles, an access element with an access element opening through which the particles can be transported into the particle receiving volume, and a closure element. The access element is selectively displaceable relative to the closure element into a closure position in which the closure element closes access opening, or into an open position in which the closure element releases the access element opening.

  • Patent number: 9977925
    Abstract: The invention relates to a slide device (1) for ascertaining an amount of insulin to be injected, comprising portions of flat material arranged in layers, which form a disk-like housing body (52), having a plurality of slide tongues displaceable counter to one another, wherein a first slide tongue (8) has a plurality of input scales (16), each with an equidistant line graduation, and a output scale (18), and can be manually grasped for the intended use and is displaceable in a first direction (14); wherein each input scale (16) is assigned a first parameter (37); wherein a second slide tongue (30) is displaceable in a second direction (32), which extends transversely to the first direction (14), and has a window (34) with a setting mark (35), which can be positioned relative to the housing body (52) in such a way that a visual inspection selectively of each of the input scales (16) is enabled; wherein next to the second slide tongue (30), a third slide tongue (38) is displaceable in the second direction (32)
