Abstract: A filter comprising a housing, which consists of at least two housing parts, and a filter element attached inside the housing. The invention provides for at least one latch element by means of which a detachable latched connection can be established between the filter element and at least one of the housing parts.

Abstract: A liquid filter includes an openable filter housing. The liquid filter has an unfiltered-liquid inlet and a clean-liquid outlet. A first filter element is arranged in the filter housing. The first filter element has an essentially hollow-cylindrical design, with the liquid flow travelling through it from the outside to the inside. An additional hollow-cylindrical filter element is arranged inside of the first filter element, wherein the liquid flow is also from the outside to the inside through the additional filter element. A separating wall is disposed between the two filter elements. The entire filter has a compact construction with a large effective filter area.

Abstract: The bow door (9) of a ferry consists of two sections (7) of the sides (5) on either side of the stem beneath the foredeck (4) and a section (10) of the foredeck lying thereabove. These side and foredeck sections (including the relevant section of the stem) are joined together to form an integral insert in the ship's hull (9). This insert can be pivoted from the closed position into an open position substantially above the foredeck (4) to provide a bow opening through said foredeck.

Abstract: An oil separator for the gases of the crankcase ventilating system of an internal-combustion engine has a filter element through which the breathing gases flow and from which the separated oil is returned via an oil return into the oil tank 4. The blow-by gases, from which the oil was removed, are supplied to the air intake system of the internal-combustion engine. A vacuum generator is provided which generates a specified constant vacuum for the sucking-off of the blow-by gases. In addition, an air oil removal element that separates the oil has microfibers which are made of fiber glass material.

Abstract: In this process for the preparation of ketene by the thermal, catalytic cracking of acetic acid under reduced pressure, the hot cracked gases are cooled to approx. 0.degree. to -10.degree. C. and, in the course thereof, water, unreacted acetic acid and acetic anhydride are condensed. The quantity of acetic acid employed for the thermal cracking reaction should be 0.5 to 2.5 t.times.hours.sup.-1 .times.m.sup.-3, relative to the volume V of a shell-and-tube heat exchanger through which the cracked gas is passed. The pressure drop in the tubular heat exchanger should be 50 to 150 mbars and the surface/volume ratio should be 60 to 120 m.sup.-1.
