  • Publication number: 20250108599
    Abstract: A dryer and shaker powder recirculating system for a direct-to-film print that includes a powder application container and a powder collection container. The system uses a vacuum, coupled to a compressor, to create a venturi suction that pulls powder from the collection container. The system also includes a joint, preferably a T-joint, that is coupled to a valve and the vacuum. The valve can be motorized, and the compressor can be tankless. The system also includes a filling tube that leads into the powder application container. The joint, vacuum, and filling tube are all connected via a series of tubes, which can be sealed against holes in the containers using tube clamps. The system can also include an inner tube that extends into the powder collection area.

  • Patent number: 4395251
    Abstract: A chain tensioning device comprises a pair of arms 2, 3 which are pivoted together and urged apart so that the arm 3 applies a tensioning force to a chain by means of a spring loaded cam block 5. A catch disc 9 and rod 8 arrangement is provided to prevent return movement of the spring loaded block and hence collapse of the arm 3 under load reversals of the chain.
