Abstract: There is disclosed a test element advancing mechanism for use in an analyzer to move such test element from station to station, and a method of doing the same. The mechanism features a support surface over which the test elements move in a predetermined direction, a test element mover for engaging and moving the test elements, means for reciprocating the mover along a surface disposed to one side of the support surface, a portion of said mover being constructed to engage the reciprocating means, and means for pivoting the mover about an axis that extends parallel to the movement direction so that the engaging means are moved into or out of contact with such test elements. The test element mover includes a lever arm emanating from one side of the reciprocating means engaging portion, constructed to interact with the pivoting means.

Abstract: A method and apparatus for opening expendable film cartridges of the type having film supply and take-up chambers joined by a hollow intermediate part having an exposure aperture. The cartridge opening apparatus has a support head for supporting a cartridge, film sensing means for sensing the type of film in the cartridge, and a movable spindle and chisel responsive to the sensing means if the film is the correct type for substantially simultaneously positioning and opening the film take-up chamber.
