Abstract: Systems are described for plant propagation and transportation. The systems include modular stackable carriers and modular stackable trays, wherein the trays accommodate plant pots, and wherein the carrier accommodate the trays. Trays and carriers may be stacked and nested in various configurations to create ensembles based on a desired functions, such as for transportation, storage or stowage.

Abstract: The present application discloses a needle tip shielding device for protection of a needle tip of a needle. The needle tip shielding device comprises a fixing arrangement having a proximal side and a distal side, which fixing arrangement is comprising at least one engaging element, which engaging element is resilient and resiliently striving from a compressed state towards an expanded state, in which expanded state the shortest distance between a point of said engaging element and the central axis of said needle tip shielding device is longer than the shortest distance between said central axis and any other point of said needle tip shielding device. A catheter instrument comprising the needle tip shielding device and a method for manufacturing is also disclosed.

Abstract: A transmission attenuating aerosol, which is transmission attenuating and has a low refractive index for electromagnetic radiation, particularly for absorption within the IR-range, which aerosol includes activated carbon having approximately 80% of the particles distributed within a range of diameters between 1 and 9 .mu.m and 10% above and below these limits, the activated carbon also being arranged having high mechanical strength.

Abstract: A third relay is provided in a signalling apparatus for ships, the apparatus primarily being intended for signalling in poor visibility and comprising an electric signalling device connectable to a current source by means of a first relay, a plurality of alternatively selectable and periodically closable make contacts connected in parallel with each other and in series with the first relay to the current source, and a second self-holding relay for coupling the motor to the current source. The third relay is connected to the current source in series with a plurality of parallel-connected switches for manual signalling, has a break contact coupled into the holding current path of the second relay and at least one make contact for connecting the signalling device to the current source.
