Claim 10
Dependent Claim
61 words
The apparatus as defined in claim 6, wherein said filter mechanism comprises a flexible filter element having an upper edge and a lower edge, a respective clamping mechanism provided for each said upper and said lower edges of said filter element, said clamping mechanisms serving to releaseably secure said flexible filter element to said inner wall portion of said double-wall jacket.
Claim 11
Dependent Claim
62 words
The apparatus as defined in claim 9, wherein said flexible filter element is provided with a respective marginal bead portion at each of its upper and lower edges, and said clamping mechanisms including clamping ring means provided for said upper and lower filter edges, said upper and lower marginal bead portions serving to secure said filter element to said clamping ring means.
Claim 12
Dependent Claim
158 words
The apparatus as defined in claim 10, wherein said filter mechanism incorporates an exchangeable filter insert, quick closure fastening means and sealing means for supporting said filter insert at said compaction compartment, said filter insert embodying said inner wall portion defining a support wall, said support wall possessing a ring flange forming at its ends forming a portion of said clamping ring means, said clamping ring means defining an upper and lower clamping ring member, said upper clamping ring member serving to clamp a ring member functioning as a pressure ring, said pressure ring functioning-clamping ring member carrying a sealing ring supported at an upper wall of said intermediate compartment, a clamping ring member serving as an attachment flange for clamping said lower clamping ring member, and a quick closure fastening mechanism for clamping said lower clamping ring member defining said attachment flange with said outer wall portion of said double-wall jacket and for retaining said filter insert.
Claim 13
Dependent Claim
33 words
The apparatus as defined in claim 1, wherein said filter mechanism comprises an exchangeable filter insert, and quick closure fastening means and sealing means for supporting said filter insert at said compaction compartment.
Claim 14
Dependent Claim
66 words
The apparatus as defined in claim 1, further including respective closure means for selectively connecting said compaction compartment with any one Of said negative pressure source, the atmospheric pressure and said overpressure source, force-actuatable elements provided for said closure means and for said inlets and outlets of said compaction compartment and supply compartment, and automatic control means for operatively coupling said force-actuation elements with one another.
Claim 15
Dependent Claim
54 words
The apparatus as defined in claim 13, wherein said control means is designed such that with closed inlet and outlet of said compaction compartment initially the closure means of the negative pressure source is opened and upon reaching a certain negative pressure in the compaction compartment the inlet of the compaction compartment is opened.
