Abstract
Abstract A pneumatic pulsator is provided for imparting vibratory motion in a liquid in a container, and the pulsator comprises a rotatable slide valve in the form of a disc, housed in a body with an inlet port and exhaust port, the disc having one or more holes or slots for periodically providing communication between the liquid in the container with a compressed air line or the atmosphere. The container is connected to the exhaust port by an outlet pipe which is coaxial with the exhaust port.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
161 words
A pneumatic pulsator for imparting vibratory motion to liquid in a container, said pulsator comprising a compressed air supply line; a body with an inlet port and an exhaust port, said inlet port communicating with said supply line, said exhaust port communicating with the atmosphere, a slide valve comprising a disc with hole means therein, said disc being rotatably housed in said body between the container and the inlet and exhaust ports, said hole means being located in said disc to be in periodic communication with said inlet and exhaust ports during rotation of the disc and provide periodic connection of the container with the compressed air supply line and with the atmosphere; means for rotating said slide valve; and an outlet pipe connected to the container and to the body coaxially with said exhaust port such that said outlet pipe is in communication with the atmosphere when the hole means in the disc is in registry with the exhaust port.
Claim 2
Dependent Claim
161 words
A pneumatic pulsator for imparting vibratory motion to liquid in a container, said pulsator comprising a compressed air supply line; a body with an inlet port and an exhaust port, said inlet port communicating with said supply line, said exhaust port communicating with the atmosphere, a slide valve comprising a disc with hole means therein, said disc being rotatably housed in said body between the container and the inlet and exhaust ports, said hole means being located in said disc to be in periodic communication with said inlet and exhaust ports during rotation of the disc and provide periodic connection of the container with the compressed air supply line and with the atmosphere; means for rotating said slide valve; and an outlet pipe connected to the container and to the body coaxially with said exhaust port such that said outlet pipe is in communication with the atmosphere when the hole means in the disc is in registry with the exhaust port.
Claim 3
Dependent Claim
51 words
A pneumatic pulsator as claimed in claim 1, wherein said hole means in said disc is constituted by a plurality of holes, some of which periodically communicate with the inlet port in the body, while others communicate with the exhaust port, the holes being located along concentric circumferences in the disc.
Claim 4
Dependent Claim
24 words
A pneumatic pulsator as claimed in claim 2 wherein said holes are constituted as circumferential sloTs extending along respective concentric circles in the discs.
Claim 5
Dependent Claim
21 words
A pneumatic pulsator as claimed in claim 2 wherein at least one of said holes is constituted as a circumferential slot.
Claim 6
Dependent Claim
43 words
A pneumatic pulsator as claimed in claim 1 comprising a connecting pipe between the body and outlet pipe and providing communication between the outlet pipe and the inlet port when the hole means in the disc is in registry with said inlet port.
Claim 7
Dependent Claim
43 words
A pneumatic pulsator as claimed in claim 1, wherein said body is hollow and said disc is mounted therein to block connection of the inlet port and exhaust port with the container except when the hole means is in registry with said ports.
Claim 8
Dependent Claim
20 words
A pneumatic pulsator as claimed in claim 1, wherein said hole means is constituted by at least one circumferential slot.
