Abstract: A plate filter having several filter plates that can be moved and pressed against each other by a closure device (6) is known. The filter plates are arranged in pairs of adjacent plates mutually linked by spacers, forming a filter chamber that is delimited by a continuous, raised sealing edge (13) on at least one filter plate (4). At least one heavy liquid inlet opens into the filter chambers, whereas at least one of the filter plates that delimit each filter chamber is provided with a compression membrane (15) that can be pressed by a pressurized medium. In addition, a filtering means (7), preferably in the shape of a ribbon, extends between two adjacent filter plates (4). In order to improve such a filter, at least one sealing edge (13; 34) of each pair of adjacent filter plates (4) has at least a marginal recess (19; 37) in which a tubular body (20; 33) that serves as a heavy liquid inlet and that extends in the direction of the sealing edge (13; 34) can be sealingly laid. The tubular body (20; 33) is provided with heavy liquid outlets (23; 38) which open into the filter chamber and the tubular bodies (20; 33) of the pile of filter plates (4) are mutually linked by spacers. The so-called cake frame can thus be dispensed with.

Title: Direct free-hand drawing on light-sensitive recording element and copying - by exposure with actinic light and development to printing plate
Inventor: BAUER GERHARD DR
IPC: G03F1/00
Filed: 1991-05-25
Abstract: The use of light-sensitive recording element as artistic medium for producing and reproducing free-hand drawings is claimed. The element consists of a dimensionally stable base and a negative- or positive-working light-sensitive layer, which is sensitive to UV and/or visible actinic light. Pref. the element may also have an optically transparent top coat contg. polymer(s) forming a tear-proof film. The drawing is made with a material which is opaque to the actinic light concerned and does not damage the surface of the recording element. The element is then totally exposed with actinic light, which causes solibility differentiation between the exposed and unexposed areas. One of these areas is washed out with a suitable developer, giving a printing plate with the motif, which is used for duplicating the motif. USE/ADVANTAGE - The technique is useful for making flat and cylindrical, gravure, offset, letterpress or flexographic printing plates. Accurate reprodns. can be obtd. without the cost of photomechanical reprodn..

Patent DE-4121581-A1 (DE)
Inventor: BURGDORF JOCHEN DIPL ING
IPC: B60T8/32
Filed: 1991-06-29
Abstract: The proposal is for a brake system with inlet valves (6, 7) in brake lines (2, 3) between the master cylinder (1) and the rear-axle wheel brakes (4, 5).
