Abstract: A message receiving arrangement operative to reduce the risk of uncontrolled distribution of transmitted and printed messages. The arrangement includes a sheet-store and printing mechanism for printing messages on sheets taken from the store and a supply of enveloping material intended for enveloping sheets with messages printed thereon. The arrangement also includes a closed casing (11) which functions to gather printed sheets to a collected bundle (33). Mounted in the casing (11) are means (25, 27, 30) which function to automatically envelope the thus gathered bundles of sheets.Also mounted in the casing (11) is a folding device (29) which, during the enveloping process, is intended to move perpendicularly to the transport direction of the sheets during the gathering of the sheets to a bundle form (33).

Abstract: An apparatus for leading off air from liquid, preferably blood, and for measuring the flow of liquid through the apparatus which comprises two chambers separated by a partition formed with a throughflow aperture. One chamber is movable in relation to the other chamber and adapted, in relation to the amount of liquid in one or the other chamber, to control a valve regulating the build-up of pressure in the apparatus.
