A magnetic sample rack adapted to support liquid containers is urged along a surface by means of a magnetic conveyor system located beneath the surface. The magnetic conveyor system comprises a plurality of magnetic housings driven by a belt, the magnetic housings including a magnet slideably contained in a closed upper cavity. Magnetic forces emanating from the magnet overcome frictional resistive forces between the sample racks and the operating surface and move the sample racks along input and output lanes defined in the operating surface. Abrupt movements of the sample racks are eliminated because the housing magnet slides smoothly towards the sample rack, secures the sample rack, and pulls the rack along the operating surface as the housings are moved at a steady rate by the belt.

A small sample cup rack adapter having a spring biased plunger moveably disposed within a generally cylindrical outer body, with the plunger adapted to support a small sample cup within the outer body. After initial contact between an aspiration probe and the bottom of the small sample cup, the probe may be lowered an additional distance, minimizing the “dead volume” of sample.

A clinical analyzer with a vision system proximate a sample tube rack, the rack having a number of different insert adapters, the adapters having markings to identify the insert, thereby identifying the type of tube. The adapters are of heights selected to position tubes of various heights at a common aspiration level. A 2-D imaging device is employed to read the markings and for analyzing various distinguishing characteristics of the sample tubes.

Disclosed are magnetic conveyor systems and apparatus having a magnetic coupling with a housing and moveable magnet therein. The moveable magnet is substantially constrained in one dimension and adapted to move in another. The moveable magnet is adapted to magnetically couple with an attracting portion of a sample rack and move the rack along a conveying surface. Ease of transfer of sample racks is provided while minimizing spillage from the open sample containers therein. Method of operating the conveyor system are provided, as are other aspects.

A tire changer having a vertical wheel hold down shaft rotatably mounted in a base cabinet and extending upward to a wheel mounting end portion above the cabinet. A collar attached to the hold down shaft beneath its mounting end portion and having a frusto-conical section extending upward to a backing flange centered about the hold down shaft. A locking pin which fits into a wheel lug hole extends upward from the flange. An upwardly extending biased centering cone slidably fitted around the hold down shaft. A bead breaker arm pivotally attached to an outside wall of the cabinet to pivot in a horizontal plane. A pneumatic cylinder is provided which is linked to both the hold down shaft and the bead breaker arm to actuate both, thus providing one pneumatic means for two different functions.

Safety apparatus for a tire changer having a support table for tire/rim assemblies and a tire inflation system includes a post having a quick disconnect mechanism for engagement with and release from the support table. The post has high pitch threads which receive a restraining cone with mating threads. The post is engaged with the table through a central rim opening and the restraining cone is moved on the threads to engage the edges of the rim opening. The post-table engagement actuates an air interlock which enables the tire inflation system. The cone is trapped on the post by structure on either end of the post.

A lower bead breaker quick release for a tire changing machine includes a manually overpowered spring lock mechanism that keeps the lower bead breaker in position during lower and upper bead breaking operations. Manual compression of the spring lock allows the lower bead breaker pivot shaft to be positioned axially to allow complete removal of the lower bead breaker from the tire changing machine. A manually actuated, friction locked lower bead breaker attitude adjustment is also provided.
