Abstract
Abstract A holder for centrifuges, for receiving specimen containers such as test tubes holding substances to be centrifuged, comprising three major parts which are connected in a form-fitting manner, namely a stirrup member, a cup member therein, and a frame in the latter, with bores in the frame for the test tubes. The cup member is preferably transparent, and the frame has apertured side portions that allow inspection of the substances in the test tubes. Photo-electric means may be provided for automatically controlling the energization of the centrifuge, depending on the progress of the settling process.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
185 words
A holder for centrifuges, adapted to receive a plurality of specimen containers such as test tubes holding substances to be centrifuged; the holder comprising, in combination: a substantially U-shaped stirrup member having a bottom plate and rigid therewith two upstanding shanks, the latter with journal pins in their terminal portions, for pivotal insertion in the head of the centrifuge; at least one cup member inserted in a form-fitting manner in said stirrup member between said shanks and held in position on said bottom plate; and at least one frame member inserted in a central opening of said at least one cup member, and having therein a plurality of bores adapted to receive test tubes, wherein said at least one cup member is made of a substantially transparent material, and said at least one frame member includes a substantially square-shaped hollow body portion, with apertured side portions that allow inspection of substances within test tubes to be inserted in said frame, a head portion having said bores therein to receive test tubes, and a bottom adapted to support terminal portions of test tubes when inserted therein.
Claim 2
Dependent Claim
185 words
A holder for centrifuges, adapted to receive a plurality of specimen containers such as test tubes holding substances to be centrifuged; the holder comprising, in combination: a substantially U-shaped stirrup member having a bottom plate and rigid therewith two upstanding shanks, the latter with journal pins in their terminal portions, for pivotal insertion in the head of the centrifuge; at least one cup member inserted in a form-fitting manner in said stirrup member between said shanks and held in position on said bottom plate; and at least one frame member inserted in a central opening of said at least one cup member, and having therein a plurality of bores adapted to receive test tubes, wherein said at least one cup member is made of a substantially transparent material, and said at least one frame member includes a substantially square-shaped hollow body portion, with apertured side portions that allow inspection of substances within test tubes to be inserted in said frame, a head portion having said bores therein to receive test tubes, and a bottom adapted to support terminal portions of test tubes when inserted therein.
Claim 3
Dependent Claim
30 words
The receptacle holder as defined in claim 1, further comprising fastening means on respective portions of said journal pins and said shanks, adapted to take up substantially high centrifugal forces.
Claim 4
Dependent Claim
24 words
The receptacle holder as defined in claim 1, wherein said stirrup member and said bottom plate are made from a single piece of material.
Claim 5
Dependent Claim
34 words
The receptacle holder as defined in claim 1, further comprising connecting means between said stirrup member and said bottom plate to immobilize the same in a form-fitting manner with respect to said stirrup member.
Claim 6
Dependent Claim
40 words
The receptacle holder as defined in claim 1, further comprising locating means in mating portions of said stirrup member and said at least one cup member to immobilize the same in a form-fitting manner with respect to said stirrup member.
Claim 7
Dependent Claim
50 words
The receptacle holder as defined in claim 4, wherein said shanks are elongated, flat members and said locating means is constituted by elongated indentations in two opposite side walls of said at least one cup member, with a shape allowing nesting therein of at least terminal portions of said shanks.
Claim 8
Dependent Claim
100 words
The receptacle holder as defined in claim 1, including a housing and a rotatable centrifuge head therein, said holder being secured to said head and describing A continuous flight path within the housing when said head is rotated, and said at least one cup member is of a substantially transparent material, and further comprising a stroboscope lamp and at least one photo-electric means secured to said housing, said flight path being between said lamp and said photo-electric means, and circuit means connected to said at least one photo-electric means to provide a signal for controlling the energization of the centrifuge.
Claim 9
Dependent Claim
68 words
The receptacle holder as defined in claim 7, wherein said at least one photo-electric means includes at least two separate photocells aligned with the apertured side portions so that test tubes as they pass in the flight path provide separate output signals for said circuit means, responsive to the light - dark jump and the dark - light jump in transparency during the settling of the substances therein.
Claim 10
Dependent Claim
25 words
The receptacle holder as defined in claim 1, wherein said stirrup member includes immobilizing means for holding in place said at least one cup member.
Claim 11
Dependent Claim
34 words
The receptacle holder as defined in claim 9, wherein said immobilizing means is in the form of a girdle member attached to said shanks, adapted to hold at least two of said cup members.
Claim 12
Dependent Claim
28 words
The receptacle holder as defined in claim 9, wherein said immobilizing means is in the form of at least a pair ledge members attached to said bottom plate.
Claim 13
Dependent Claim
33 words
The receptacle holder as defined in claim 9, wherein said immobilizIng means is in the form of a trough attached to said bottom plate, adapted to hold a plurality of said cup members.
