Abstract
Abstract An electrophoretic apparatus for use in a quantitative analysis of a specimen such as a blood serum applied to a belt-like carrier body, which is capable under the unified conditions of performing the electrophoresis for the blood serum by applying direct voltage to the latter through the carrier body and comprises a main body having a pair of buffer solution troughs respectively containing a buffer solution, a transport means for transporting the carrier body into and out of the main body, a pair of high absorbent paper at least a part of each of which is dipped into the buffer solution in respective buffer solution troughs and contacting means for contacting each side end portion of the carrier body with each one of the high absorbent paper, whereas the direct voltage is applied to the carrier body through the buffer solution and said pair of high absorbent paper.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
245 words
An electrophoretic apparatus for use in an analysis of a specimen such as blood serum applied to a belt-like carrier body comprising: a main body having a chamber portion and entrance and exit windows formed in the opposite portions of the chamber portion, a pair of buffer solution troughs disposed in the chamber portion and respectively containing a buffer solution, a transport means for transporting the carrier body from the entrance window into the chamber portion and out of the chamber portion from the exit window, a pair of high absorbent papers at least a part of each one of which is dipped into the buffer solution in respective buffer solution troughs, a pair of contacting means movably disposed in the chamber portion for contacting each side end portion of the carrier body placed in the chamber portion with respective ones of said pair of high absorbent papers, including an operating rod rotatably mounted on said main body, at least a pair of cam disks mounted on said rod for rotation therewith, a pair of arms each engaging a cam surface of a cam disk for movement as said disk is rotated, and a pair of pressing plates each mounted on one of said arms for pressing said carrier body into contact with one of said papers, wherein direct voltage is applied across both side end portions of the carrier body through the buffer solution in each buffer solution trough and respective high absorbent paper.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
45 words
An apparatus as in claim 1, wherein each of said pressing plates has a flat surface extending parallel to the paper it contacts and wherein said arms extend substantially horizontal and wherein said contacting means further includes vertical rods connecting said plates to said arms.
Claim 4
Dependent Claim
48 words
An apparatus as in claim 2, wherein said transport means includes first and second endless belts for engaging said carrier and means for driving said belt and further including further pressing plates for engaging said belts and further vertical rods connecting said further plates to said horizontal arms.
Claim 5
Dependent Claim
40 words
An apparatus as in claim 2, further including a pair of wires mounted adjacent to said pressing plates for disengaging said carrier body from said pressing plates when said pressing plates are moved out of contact with said carrier body.
Claim 6
Dependent Claim
35 words
An apparatus as in claim 1, wherein said pressing plates are mounted below said carrier and wherein said contacting means includes vertically movable rods and connecting bars connecting said pressing plates to said rigid arms.
Claim 7
Dependent Claim
33 words
An apparatus as in claim 5 further including wires mounted adjacent said pressing plates for disengaging said body from said plates when said plates are moved out of contact with said carrier body.
Claim 8
Dependent Claim
40 words
An apparatus as in claim 5, further including shutter members for opening and closing said entrance and exit windows and means connecting said operating rod to said shutter means for closing said windows when said pressing plates contact said papers.
Claim 9
Dependent Claim
232 words
An electrophoretic apparatus for use in an analysis of a specimen such as blood serum applied to a belt-like carrier body comprising: a main body having a chamber portion and entrance and exit windows formed in the opposite portions of the chamber portion, a pair of buffer solution troughs disposed in the chamber portion and respectively containing a buffer solution, a transport means for transporting the carrier body from the entrance window into the chamber portion and out of the chamber portion from the exit window, a pair of high absorbent papers at least a part of each one of which is dipped into the buffer solution in respective buffer solution troughs, a pair of contacting means movably disposed in the chamber portion for contacting each side end portion of the carrier body placed in the chamber portion with respective ones of said pair of high absorbent papers including a pair of bar-like pressing members, rotatably mounted on said main housing and having sector shaped cross-sections, an operating rod rotatably mounted on said main body, and means connecting said operating rod to said pressing members for rotating said pressing members to engage said carrier body and press said body into contact with said papers, wherein direct voltage is applied across both side end portions of the carrier body through the buffer solution in each buffer solution trough and respective high absorbent paper.
Claim 10
Dependent Claim
232 words
An electrophoretic apparatus for use in an analysis of a specimen such as blood serum applied to a belt-like carrier body comprising: a main body having a chamber portion and entrance and exit windows formed in the opposite portions of the chamber portion, a pair of buffer solution troughs disposed in the chamber portion and respectively containing a buffer solution, a transport means for transporting the carrier body from the entrance window into the chamber portion and out of the chamber portion from the exit window, a pair of high absorbent papers at least a part of each one of which is dipped into the buffer solution in respective buffer solution troughs, a pair of contacting means movably disposed in the chamber portion for contacting each side end portion of the carrier body placed in the chamber portion with respective ones of said pair of high absorbent papers including a pair of bar-like pressing members, rotatably mounted on said main housing and having sector shaped cross-sections, an operating rod rotatably mounted on said main body, and means connecting said operating rod to said pressing members for rotating said pressing members to engage said carrier body and press said body into contact with said papers, wherein direct voltage is applied across both side end portions of the carrier body through the buffer solution in each buffer solution trough and respective high absorbent paper.
