Abstract: A device for recording, handling and documentation of time/activity data. The duration of different categories of work occasions and/or activities, as for example down time, can be measured by activation of a press button corresponding to each category of work. A pulse train (11), generated in a pulse generator (10), is provided to at least one of a plurality of storage cells (12). As the time between two pulses (11a), following after each other, is constant and known, e.g. one hundredth of an hour, the total number of pulses (11a) the storage cells (12) are fed with, will correspond to a time value required for the respective output of work and/or activity. When desired the information content of all storage cells (12) is read. This information is converted and/or handled and the result is printed (7) in a manually readable form on an information carrier (6). The information content of the storage cells (12) can also be transferred to and handled by a central reading unit.

Abstract: An apparatus for manufacturing or treating a stencil intended for use in a silkscreen printing machine. The stencil has been lighttreated to transfer a design to a pre-treated net or film. The film being subjected to a water-treatment process to rinse the film to develop said pattern. The apparatus comprises at least two pipes having mutually facing nozzles and being arranged to co-act with a displaceable holder in a manner such one of said at least two pipes passes on the rear of the film and the other of said at least two pipes passes on the other side of said film.
