Abstract: The present invention provides a device for heat-treating a coating of flat-bed offset printing plates by application of hot air upon the flat-bed offset printing plates, comprises an upper hot-air chamber: a lower hot-air chamber, arranged at a distance from the upper hot-air chamber below the latter; an air-permeable endless conveyer belt having a carrying run, which extends between the upper and the lower hot-air chambers; a first air diffuser provided on the bottom of the upper hot-air chamber, and a second air diffuser provided on the top of the lower hot-air chamber. The two air diffusers are provided with air outlet openings that face the conveyer belt and at least one air inlet opening which is connected with the intake side of one or more blowers. The space between the two hot-air chambers, except for an entry opening for the carrying run and an exit opening for the carrying run for the conveyer belt, is closed.

Abstract: The invention describes an ash collector for smokers, which is characterized by a bar-shaped container with an opening on one end that is closed by a removable closure body which consists, in full or predominantly, of a material resistant to the glowing ash or cigarettes of cigars.

Abstract: A device for washing and drying printing plates has a run-in table (1) followed by a series of washing, rinsing, conserving and/or gumming and drying stations (2, 3, 4, 5), and pairs of rolls (10, 11) arranged in the various stations with a horizontal axis of rotation and a roll slit that lies at the level of the run-in table (1). At least one roll of each pair of rolls (10, 11) may be driven so as to feed the printing plates engaged by the rolls (10, 11) through the roll slit. The device finally has a run-out table (6). In all stations (2, 3, 4, 5) are provided longitudinal guiding means (12) aligned in a common line together with the conveyor (26) of the pairs of rolls (10, 11) All longitudinal guiding means (12) lie either above or below the roll slit and delimit after the roll slit an obstacle-free passage through all stations (2, 3, 4, 5).
