An apparatus for filtering fluids, which comprises: a. a housing, comprising 1. a filter chamber including a first end wall having an opening, a second end wall having an opening, and a first enclosing side wall having a filtrate opening; 2. a first sealing chamber including the first end wall, a third end wall having an opening, and a second enclosing side wall; and
Claim 2
Independent Claim
64 words
An apparatus for filtering fluids, which comprises: a. a housing, comprising 1. a filter chamber including a first end wall having an opening, a second end wall having an opening, and a first enclosing side wall having a filtrate opening; 2. a first sealing chamber including the first end wall, a third end wall having an opening, and a second enclosing side wall; and
Claim 3
Dependent Claim
206 words
a second sealing chamber including the second end wall, a fourth end wall having an opening, and a third enclosing side wall; b. a tubular fluid inlet member slidably movable through the openings in the end walls in the housing, which includes at a first end a first section, a second section, and a perforated medial section which is located intermediate the first section and second section; c. tubular filter media extendable through the openings in the end walls in the housing; d. means for displacing the tubular fluid inlet member and the tubular filter media so that during filtration the first end of the tubular fluid inlet member extends into the housing through the tubular filter media for positioning the first section in the first sealing chamber, the medial section in the filter chamber, and the second section in the second sealing chamber, and after filtration the length of tubular filter media in which the filtered solids are retained and the second section and medial section of the tubular fluid inlet member are displaced from the housing; and e. means for sealing the filter chamber which cooperate with the first section and second section of the tubular fluid inlet member to seal the filter chamber.
Claim 4
Dependent Claim
206 words
a second sealing chamber including the second end wall, a fourth end wall having an opening, and a third enclosing side wall; b. a tubular fluid inlet member slidably movable through the openings in the end walls in the housing, which includes at a first end a first section, a second section, and a perforated medial section which is located intermediate the first section and second section; c. tubular filter media extendable through the openings in the end walls in the housing; d. means for displacing the tubular fluid inlet member and the tubular filter media so that during filtration the first end of the tubular fluid inlet member extends into the housing through the tubular filter media for positioning the first section in the first sealing chamber, the medial section in the filter chamber, and the second section in the second sealing chamber, and after filtration the length of tubular filter media in which the filtered solids are retained and the second section and medial section of the tubular fluid inlet member are displaced from the housing; and e. means for sealing the filter chamber which cooperate with the first section and second section of the tubular fluid inlet member to seal the filter chamber.
Claim 5
Dependent Claim
106 words
A fluid filtering apparatus as recited in claim 1, in which the first section of the tubular fluid inlet member comprises a first mandrel, the second section of the tubular fluid inlet member comprises a second mandrel, and the sealing means comprise a first tubular flexible seal mounted in the first sealing chamber, a second tubular flexible seal mounted in the second sealing chamber, and means for expanding the first tubular flexible seal and the second tubular flexible seal so that during filtration the first tubular flexible seal is expanded about the first mandrel and the second tubular flexible seal is expanded about the second mandrel.
Claim 6
Dependent Claim
133 words
A fluid filtering apparatus as recited in claim 1, in which the tubular fluid inlet member includes, at the second end, a guide rail, a rack having a blank section, and a pawl pivotally mounted in the blank section of the rack, and in which the displacing means includes a second housing, a first shaft rotatably journalled in the second housing, a pinion gear mounted on the first shaft engageable with the rack or pawl, a second shaft rotatably journalled in the second housing, a guide wheel engageable with the tubular filter media mounted on the second shaft, a guide wheel gear mounted on the second shaft, and a gear train mounted in the second housing engaged with the pinion gear at one end and the guide wheel gear at the other end.
Claim 7
Dependent Claim
42 words
A fluid filtering apparatus as recited in claim 2, in which the first tubular flexible seal and second tubular flexible seal are expandable to seal about the ends and along the medial portion of the first mandrel and the second mandrel respectively.
Claim 8
Dependent Claim
50 words
A fluid filtering apparatus as recited in claim 3, in which the guide wheel has openings at circumferential locations, and includes a plurality of fingers radially extendable, and means for reciprocally extending and retracting the fingers radially through the circumferential wheel openings to engage and release the tubular filter media.
Claim 9
Dependent Claim
52 words
A fluid filtering apparatus as recited in claim 3, further comprising means for supporting the other end of the tubular fluid inlet member, comprising a bracket support plate including first rollers mounted therein which bear against the tubular fluid inlet member, and second rollers mounted therein which bear against the guide rail.
Claim 10
Dependent Claim
30 words
A fluid filtering apparatus as recited in claim 3, further comprising slitting wheels mounted at one end of the housing in the path of displacement of the tubular filter media.
