Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
144 words
A pump for pumping solid articles of a predetermined size, said pump comprising: a housing having walls defining a cylindrical impeller chamber, an inlet coaxial with and communicating with said chamber, and an outlet communicating with and extending outward with the outermost wall thereof at a tangent to the outer periphery of same chamber, a multiple disc impeller rotatably mounted coaxially within said impeller chamber in said housing and having at least a first pair of coaxially disposed flat smooth continuous surface discs closely spaced a first distance apart defining a first path therebetween to permit free-flow of fluid via said first path to said outlet and so disposed within said housing to define a second path for unobstructed passage of articles, of a predetermined size greater than said first distance from said inlet past said discs via said second path to said outlet.
Claim 2
Dependent Claim
144 words
A pump for pumping solid articles of a predetermined size, said pump comprising: a housing having walls defining a cylindrical impeller chamber, an inlet coaxial with and communicating with said chamber, and an outlet communicating with and extending outward with the outermost wall thereof at a tangent to the outer periphery of same chamber, a multiple disc impeller rotatably mounted coaxially within said impeller chamber in said housing and having at least a first pair of coaxially disposed flat smooth continuous surface discs closely spaced a first distance apart defining a first path therebetween to permit free-flow of fluid via said first path to said outlet and so disposed within said housing to define a second path for unobstructed passage of articles, of a predetermined size greater than said first distance from said inlet past said discs via said second path to said outlet.
Claim 3
Dependent Claim
26 words
The pump of claim 1, including one pair of discs adjacent said inlet and said one pair of discs includes an opening in the center thereof.
Claim 4
Dependent Claim
36 words
The pump of claim 1, wherein said impeller comprises a drive disc mounted on a drive shaft, and defining a third disc, said first pair of discs being connected to and spaced from the drive disc.
Claim 5
Dependent Claim
37 words
The pump of claim 1, wherein said impeller includes in addition to said first pair of discs a third disc spaced a second distance from one of said first pair of discs to define said second path.
Claim 6
Dependent Claim
32 words
The pump of claim 4, wherein said second distance is at least one fourth of an inch and said first distance is between one ten thousandths and one quarter of an inch.
Claim 7
Dependent Claim
21 words
The pump of claim 3, wherein said first distance is between one ten thousandths and one and one-half of an inch.
Claim 8
Dependent Claim
41 words
The pump of claim 6, wherein said first pair of discs include means defining a hole through the center thereof and defining an inner diameter thereof, and a plurality of bolts connecting said discs together closely adjacent the inner diameter thereof.
Claim 9
Dependent Claim
16 words
The pump of claim 7, wherein said second distance is greater than one and one-half inches.
Claim 10
Independent Claim
114 words
A method of transporting solid articles of a predeter-mined size from a first location to a second location, compris-ing the steps of: selecting a rotary disc impeller pump having an inlet and an outlet, pairs of closely spaced discs for increasing the pressure therein and a spacing between at least a pair of discs sufficient to permit unobstructed passage of solid articles of a predetermined size, connecting said pump in conduit means extending between said first location and said second location, selecting solid articles of a predetermined size to be transported, introducing said articles into a liquid, and thereby forming a mixture, and introducing said mixture into the pump inlet at said first location.
Claim 11
Independent Claim
114 words
A method of transporting solid articles of a predeter-mined size from a first location to a second location, compris-ing the steps of: selecting a rotary disc impeller pump having an inlet and an outlet, pairs of closely spaced discs for increasing the pressure therein and a spacing between at least a pair of discs sufficient to permit unobstructed passage of solid articles of a predetermined size, connecting said pump in conduit means extending between said first location and said second location, selecting solid articles of a predetermined size to be transported, introducing said articles into a liquid, and thereby forming a mixture, and introducing said mixture into the pump inlet at said first location.
Claim 12
Dependent Claim
24 words
The method of claim 9, wherein the step of selecting said articles includes selecting said articles from the class consisting of fruits and vegetables.
Claim 13
Dependent Claim
28 words
The method of claim 9, wherein the step of selecting said articles includes selecting said articles from the class consisting of marbles, rock, coal particles, and glass particles.
