Abstract
Abstract Method and apparatus for generating centrifugal forces, including a plate rotatable about an axis, and at least one holding means mounted on the plate for rotation therewith, the holding means being adapted to receive an article to be subjected to centrifugal force and being rotatable relative to the plate member to permit the direction of centrifugal force acting on the article to be changed.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
84 words
Apparatus for generating centrifugal forces comprising: (a) a plate member adapted to rotate about an axis, and (b) at least one holding means mounted on the plate member for rotation therewith, said holding means being adapted to receive an article to be subjected to centrifugal force and being rotatable relative to the plate member whereby rotation of the holding means relative to the plate member during rotation of the plate member about said axis changes the direction of centrifugal force acting on said article.
Claim 2
Dependent Claim
84 words
Apparatus for generating centrifugal forces comprising: (a) a plate member adapted to rotate about an axis, and (b) at least one holding means mounted on the plate member for rotation therewith, said holding means being adapted to receive an article to be subjected to centrifugal force and being rotatable relative to the plate member whereby rotation of the holding means relative to the plate member during rotation of the plate member about said axis changes the direction of centrifugal force acting on said article.
Claim 3
Dependent Claim
17 words
Apparatus as defined in claim 1 which includes means for rotating the plate member about said axis.
Claim 4
Dependent Claim
19 words
Apparatus as defined in claim 1 which includes means to rotate the holding means relative to the plate member.
Claim 5
Dependent Claim
37 words
Apparatus as defined in claim 3 wherein the means to rotate the holding means includes a rotatable shaft fixed to and carrying the holding means, and drive means to rotate said shaft to turn the holding means.
Claim 6
Dependent Claim
21 words
Apparatus as defined in claim 4 wherein the drive means includes motor means to drive said shaft to rotate said shaft.
Claim 7
Dependent Claim
20 words
Apparatus as defined in claim 5 wherein the motor means drives gear means, and- the gear means drives said shaft.
Claim 8
Dependent Claim
19 words
Apparatus as defined in claim 6 which includes clutch means to releasably engage the gear means from said shaft.
Claim 9
Dependent Claim
20 words
Apparatus as defined in claim 1 wherein the holding means includes means to secure said article thereto for rotation therewith.
Claim 10
Dependent Claim
100 words
Apparatus for carrying out chemical testing under centrifugal force comprising: (a) a plate member adapted for rotation about an axis, (b) holding means mounted on said plate member for rotation therewith, said holding means being rotatable relative to the plate member as the plate member rotates about said axis and being adapted to receive sample processor means for carrying out chemical testing, whereby the holding means is rotated during rotation of the plate member to change the direction of the centrifugal force acting on the sample processor means to effect testing of a sample placed in the sample processor means.
Claim 11
Dependent Claim
100 words
Apparatus for carrying out chemical testing under centrifugal force comprising: (a) a plate member adapted for rotation about an axis, (b) holding means mounted on said plate member for rotation therewith, said holding means being rotatable relative to the plate member as the plate member rotates about said axis and being adapted to receive sample processor means for carrying out chemical testing, whereby the holding means is rotated during rotation of the plate member to change the direction of the centrifugal force acting on the sample processor means to effect testing of a sample placed in the sample processor means.
Claim 12
Dependent Claim
17 words
Apparatus as defined in claim 9 which includes means for rotating the plate member about said axis.
