Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
127 words
Apparatus for posing documents at a station, posed documents being registered with respect to an imaginary plane and an axis perpendicular thereto, comprising (a) means for feeding documents: (b) fluidic means for receiving and registering said documents at the station, the fluidic means including: a sleeve for internally accommodating said documents, at least a plurality of points on an inner narrow wall of the sleeve being located on the imaginary plane, a stop having at least one point aligned with the axis, and means, including at least one port in said stop and at least one port in said narrow wall, for providing in the sleeve a first fluid stream having velocity components normal to the imaginary plane and axis; and (c) means for collecting discharged documents.
Claim 2
Dependent Claim
127 words
Apparatus for posing documents at a station, posed documents being registered with respect to an imaginary plane and an axis perpendicular thereto, comprising (a) means for feeding documents: (b) fluidic means for receiving and registering said documents at the station, the fluidic means including: a sleeve for internally accommodating said documents, at least a plurality of points on an inner narrow wall of the sleeve being located on the imaginary plane, a stop having at least one point aligned with the axis, and means, including at least one port in said stop and at least one port in said narrow wall, for providing in the sleeve a first fluid stream having velocity components normal to the imaginary plane and axis; and (c) means for collecting discharged documents.
Claim 3
Dependent Claim
36 words
Apparatus as defined in claim 1 wherein said fluidic means include means for providing a second fluid stream in the sleeve for discharging registered documents, said first and second streams being present in the sleeve alternatively.
Claim 4
Dependent Claim
23 words
Apparatus as defined in claim 1 wherein said means for providing a fluid includes a fluid source for injecting fluid into the sleeve.
Claim 5
Dependent Claim
33 words
Apparatus as defined in claim 3 wherein said means for providing a fluid includes a manifold coupled to at least one of the ports and a pump for discharging fluid from the manifold.
Claim 6
Dependent Claim
25 words
Apparatus as defined in claim 4 wherein said fluid source includes apparatus for directing fluid under pressure, and said apparatus is coupled to said pump.
Claim 7
Dependent Claim
11 words
Apparatus as defined in claim 5 wherein said pump is reversible.
Claim 8
Dependent Claim
20 words
Apparatus as defined in claim 1 wherein said sleeve includes a pivotally mounted top plate and a translucent bottom plate.
Claim 9
Dependent Claim
27 words
Apparatus as defined in claim 7 wherein said means for providing a fluid includes a fluid source for injecting fluid into the sleeve at its other end.
Claim 10
Dependent Claim
33 words
Apparatus as defined in claim 7 wherein said means for providing a fluid includes a manifold coupled to at least one of the ports and a pump for discharging fluid from the manifold.
Claim 11
Dependent Claim
129 words
Apparatus for posing documents at a station in a sleeve, comprising: (a) means for serially feeding documents from a stack of documents; (b) fluidic means for serially moving documents in a first direction into registration at the station and for subsequently moving registered documents in an opposite direction; (c) means for collecting documents; and (d) means, adjacent to the sleeve, for engaging documents moved out of registration and moving engaged documents into said means for collecting documents, the rate at which documents are fed being long enough to allow engagement of a document moved out of registration before the next serially delivered document is moved into the sleeve, whereby at least a part of two documents can be present in overlapping relationship in the sleeve at the same time.
Claim 12
Dependent Claim
129 words
Apparatus for posing documents at a station in a sleeve, comprising: (a) means for serially feeding documents from a stack of documents; (b) fluidic means for serially moving documents in a first direction into registration at the station and for subsequently moving registered documents in an opposite direction; (c) means for collecting documents; and (d) means, adjacent to the sleeve, for engaging documents moved out of registration and moving engaged documents into said means for collecting documents, the rate at which documents are fed being long enough to allow engagement of a document moved out of registration before the next serially delivered document is moved into the sleeve, whereby at least a part of two documents can be present in overlapping relationship in the sleeve at the same time.
Claim 13
Dependent Claim
91 words
Apparatus as defined in claim 10 wherein said documents are registered with respect to an imaginary plane parallel to said first direction and an axis perpendicular to the plane, wherein at least a plurality of points on an inner narrow wall of the sleeve are located on the imaginary plane; wherein the sleeve includes a stop having at least one point aligned with the axis; and wherein the fluidic means includes means for providing in the sleeve a first fluid stream having velocity components normal to the imaginary plane and axis.
Claim 14
Dependent Claim
56 words
Apparatus as defined in claim 11 wherein said fluidic means include means for providing a second fluid stream in the sleeve for moving documents in said opposite direction; wherein said means for serially feeding documents includes at least one roller pair; and wherein said means for engaging documents cooperates with said means for serially feeding documents.
