Abstract: ABSTRACT Disclosed are methods and devices for deter-mining blood group classifications from blood or serum samples.  The test device comprises:  (a) a porous solid substrate and (b) one or more essentially pure anti-bodies specifically reactive with erythrocyte antigenic determinants characterizing blood groups wherein the antibodies are bound to the porous solid substrate in an array of delimited adsorption areas of differing spe-cificities such that they are capable of binding erythrocytes for which they are specifically reactive so as to produce detectable color signals.  The test device may be used to determine the blood group classification of a sample by (a) incubating the test device with a sample of blood, the type of which is to be determined; (b) rinsing the test device and (c) detecting a color signal from erythrocytes bound to antibodies which are themselves bound to the solid substrate.

One of the rotatable members carries no cutting blades, and the second rotatable  member  carries  a  plurality  of  double-edged, circumferentially spaced blades that individually cooperate with the non-rotatable blade in a shearing action. The non-rotatable member includes a protruding, forwardly expanding, wedge member, the wedge member being configured to define a forwardly opening wedge-shaped cavity.  The wedge-shaped cavity is adapted to receive, and interact with, the propeller shaft housing. The rotatably mounted annular bolt ring is disposed intermediate the non-rotatable cutting ring and the propeller shaft housing. The rotatably mounted annular cutter ring is mounted rearwardly of the non-rotatably mounted cutting ring so that the non-rotating cutter ring is disposed in sandwiched relation to the bolt ring and the rotatable cutter ring. The protruding wedge members cavity enters into abutting engagement with the propeller shaft housing attendant rotation of the propeller shaft, the propeller shaft housing entering into fine engagement with the forwardly opening wedge-shaped cavity substantially instantaneously upon the introduction of a load on the apparatus
