Abstract: In a storage phosphor reader having a receiving station for receiving a cassette containing a removable storage phosphor, the storage phosphor having an end cap with an alignment opening and access openings, an extraction bar assembly comprising: an extraction bar; a locator pin and spaced hook members projecting from the extraction bar toward a received cassette; a slider for mounting the locating pin, the slider being slidably mounted on the extraction bar; an over center spring connected between the slider and the extraction bar; mechanism for moving the extraction bar towards a received storage phosphor so that the locator pin and hook members are respectively inserted into the alignment opening and the access openings of the storage phosphor end cap and then for moving the extraction bar laterally of the storage phosphor so that the hook members engage the end cap of the storage phosphor, the slider slides in the extraction bar, and the over center spring locks the hook members in the engaged position; a

Abstract: A batch mixer for mixing a container of concentrate and diluent, the batch mixer comprises a mixing tank; and a drawer assembly for delivering the concentrate to said mixing tank. The drawer includes a multiple position receiving station for permitting the concentrate to be arranged in a plurality of configurations.

Abstract: A supply magazine for use in an apparatus for removing individual film that has been placed within a light-tight pouch having a leader secured to the leading edge. The magazine has a base which receives and retains a stack of sheet film within the light-tight pouch, and a cover secured to the base which can be rotated between a closed position and an open position. A take-up spindle is rotatably secured within the base for winding of the pouch thereon. The improvement comprises a lever arm for biasing the leader toward the spindle which cooperates with hook provided on the spindle when the cover is in the closed position. The lever arm includes a clamp pad which has a configuration which forms a resistive wall section in the leader when the magazine is in the closed position such that when the spindle is rotated, the hooks will engage the leader at the resistive wall section allowing the pouch to be wound around the spindle.

Abstract: A package for a stack of X-ray film sheets has a pouch and a leader secured to the pouch. Heat seals secure side edge portions of the leader to edges of outer faces of sheets forming the pouch. Rows of perforations and slits in the leader adjacent the heat seals enables tearing of the leader from the pouch edges.

Abstract: A package for a stack of film sheets has a pouch that is sealed around the stack of sheets and a leader that is secured to the pouch and engageable with a spindle in a magazine so that rotation of the spindle can pull the pouch from around the stack of sheets. The pouch and leader are formed of different polyolefin materials with the pouch comprising a material having a low coefficient of friction to enable the pouch to be easily pulled around the stack of sheets while the leader comprises a material having a high coefficient of friction to facilitate engagement with the spindle and pulling the pouch uniformly.

Abstract: A heat exchanger comprising a conduit formed by two elongated channel forming sheets bound and sealed together along facing flat edges by encapsulating plastic extending around the edges of the sheets and extending through matching openings in the flat sheet edges. The encapsulation is preferably carried out as part of the reaction injection molding of a container, with the heat exchanger encapsulated in a wall of the container.

Abstract: Processing apparatus for photographic film, particularly intraoral xray film, in which the various processing stations are positioned in a circle about a central rotatable column. The column has an external spiral groove in which rides a pin carried by, and extending into the bore of, a hub which fits around the column. Rotation of the column moves the hub up or down, depending upon the direction of rotation. The hub carries a plurality of arms equal in number to the number of stations, seven in the apparatus disclosed. Each arm has a magnet for attaching a novel film holder which is detachable at the unloading station. After loading a film holder with film to be processed, the holder is loaded into the machine through a spring-pressed loading door onto a loading platform which moves the film holder upwardly to engage it with one of the arms when the door is closed.
