Abstract
Abstract A process and a gel cutting device constructed and adapted to remove gel like material from a surface, the device having a hollow body with fluid communication therethrough, a pickup conduit attached to the inlet of the body, a cutter on the inlet end of the pickup conduit. The outlet of the body is connectable to a vacuum source. In operation the process and the gel cutter have the cutter of the pickup conduit passed into gel material, cutting same and passing the removed material through the pickup conduit into the hollow body.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
241 words
A gel cutting apparatus comprising a hollow substantially cylindrical body having an inlet and an outlet to provide fluid communication therethrough, a cutter portion attached to said inlet, a vacuum pressure source connected to said outlet, said cutter portion including a structure defining an essentially elongated conduit having a flattened end and having an edge portion defining a substantially elliptical structure sharpened on its periphery, said elongated conduit including an internal diameter smaller than the internal diameter of said hollow body to provide greater suction force in said elongated cutter portion, said flattened end facilitates directing said apparatus in an essentially linear path over a gel surface and includes an areal opening smaller than the internal areal opening of said elongated conduit of said cutter portion to provide a greater suction force at said opening of said flattened end for easy removal of said gel and said gel cutting apparatus traverses a generally linear path over said gel surface, said cutter portion is essentially longer than said hollow body, said hollow body comprises a first conduit section having a second outlet end and said inlet and a second conduit section including a second inlet end and said outlet, said second outlet end removably lodges within said second inlet end, said inlet and said outlet generally comprise approximately identical diameters such that said inlet may be attached to said vacuum pressure source and said outlet may be connected to said cutter portion.
Claim 2
Dependent Claim
241 words
A gel cutting apparatus comprising a hollow substantially cylindrical body having an inlet and an outlet to provide fluid communication therethrough, a cutter portion attached to said inlet, a vacuum pressure source connected to said outlet, said cutter portion including a structure defining an essentially elongated conduit having a flattened end and having an edge portion defining a substantially elliptical structure sharpened on its periphery, said elongated conduit including an internal diameter smaller than the internal diameter of said hollow body to provide greater suction force in said elongated cutter portion, said flattened end facilitates directing said apparatus in an essentially linear path over a gel surface and includes an areal opening smaller than the internal areal opening of said elongated conduit of said cutter portion to provide a greater suction force at said opening of said flattened end for easy removal of said gel and said gel cutting apparatus traverses a generally linear path over said gel surface, said cutter portion is essentially longer than said hollow body, said hollow body comprises a first conduit section having a second outlet end and said inlet and a second conduit section including a second inlet end and said outlet, said second outlet end removably lodges within said second inlet end, said inlet and said outlet generally comprise approximately identical diameters such that said inlet may be attached to said vacuum pressure source and said outlet may be connected to said cutter portion.
Claim 3
Dependent Claim
33 words
The gel cutting apparatus of claim 1 wherein said hollow body additionally includes thereon a means providing a handle thereon for pushing said flattened end in a linear path over said gel surface.
Claim 4
Dependent Claim
21 words
The gel cutting apparatus of claim 2 wherein said second outlet end and said second inlet end are essentially cylindrically shaped.
Claim 5
Dependent Claim
31 words
The gel cutting apparatus of claim 3 wherein said means providing a handle comprises a plurality of circular flanges circumferentially attached to said first conduit section and said second conduit section.
