Black-and-white elements, such as radiographic films, can be processed in roomlight because they include certain light absorbing dyes and desensitizers. Processing of such elements can be achieved using a processing kit and a two-stage process carried out in the same light- and fluid-tight processing apparatus. In the first stage, development is initiated with a developing composition having a pH of from about 10 to about 12.5, and comprising an appropriate black-and-white developing agent and a sulfite. After an appropriate time, a non-sulfite fixing agent is introduced into the processing apparatus or container to provide a combined developing/fixing composition, and development and fixing are carried out simultaneously. The processing method is carried out quickly, usually within about 90 seconds. The presence of sulfite and high pH in both stages decolorizes or deactivates the particulate dyes. The processing kit includes the photographic element, a vessel containing a developing composition, a vessel containing fixing composition, and a light-tight, hand-held container for holding an exposed element as it is inserted into the first and second vessels to carry out processing.

An article of manufacture adapted to be connected to a male thread comprises an exterior surface, a cavity opening away from the exterior surface and defining an interior surface, and a plurality of ribs disposed on the interior surface extending longitudinally away from the exterior surface. The article can be connected to the male thread by threading the cavity onto the male thread. It is a particular advantage that the article of this invention, unlike prior art female threaded articles, can be prepared by conventional simple injection molding techniques not requiring an unscrewing step. In one preferred embodiment, the article is a plunger rod intended to be connected to the male threaded post of a plunger of an associated cartridge-needle unit to form a syringe assembly.

This invention relates to a holder for use in combination with a pre-filled cartridge-needle unit, the holder comprising a hollow body sized for housing the cartridge-needle unit therein, and provision for allowing the body to move axially relative to the cartridge-needle unit. In one preferred embodiment, the distal end of the body is elliptical in cross section and the proximal end of the body is circular in cross section. In another preferred embodiment, the body comprises a pair of cam slots at the distal end and a pair or retaining slots at the proximal end, the slots being sized to accept a circumferential ring on the cartridge-needle unit and positioned to hold the cartridge-needle units in use and safe positions. The holder is easier to use and manufacture and reduces the susceptibility of health care workers to accidental needle strikes.

Holder for cartridge-needle unit

An apparatus is disclosed for loading a photographic camera (426) of a type including an external housing (428, 478) having a movable closure (484) giving access to a film guide track (566) within the camera, the guide track extending between an unexposed film chamber (562) and an exposed film chamber (564), the apparatus including a frame (12); a source (24) for unexposed photographic film positioned on the frame; a nest for receiving the camera supported on the frame; a film loading device (72) extending between the source and the nest for guiding film from the source into the film guide track within the camera; a film unloading device (82) extending away from the camera; and means for driving film from the source, along the loading device and into said camera and for driving film from the camera along the unloading device. Corresponding methods also are taught.

Apparatus (610) is disclosed for opening and closing a photographic camera (426) of a type including an external housing (428, 478) having a slidable closure (484) giving access to a film guide track (566) within the camera, the closure including an externally accessible slot (636), the guide track extending between an unexposed film chamber (562) and an exposed film chamber (564). The apparatus may include a frame (12); a nest (74) supported on the frame for receiving a camera; and a door opening mechanism (612-646) supported by the frame, the mechanism including a member (632, 634) for engaging the slot and an actuator (616, 628) for moving the member to open the closure.

Apparatus is disclosed for actuating and testing a camera (426) of a type including a shutter trigger button (438) and externally accessible features (476, 508, 526, 530) for moving film within the camera. The apparatus may include a support frame (12); a nest (74) supported by the frame, the nest having a base (410) and walls (420, 422, 424) for guiding a camera into position on the base; a device (664-668) associated with the nest for depressing the trigger button to actuate and test a shutter mechanism of a camera; and camera drive mechanism (584-604) associated with the nest for engaging and operating the device for moving to drive exposed film from the exposed film chamber to the unexposed film chamber and then drive exposed film from the unexposed film chamber along the film guide track and out of the camera. Sensors may be included for detecting whether a lens cover is open or closed ((454-458), for detecting whether or not a flash switch is in a on or off position ((462-468), for detecting whether or not a flash ready light is illuminated (701,702), for releasing a zero lock mechanism (684), for sensing the presence of a camera in the nest (444-448) and for detecting whether or not a flash feature functions (698,700).

This invention relates to a collar adapted for use in combination with activatable prefilled cartridge-need units and disposable holders. The collar is adapted to fit over the hub of the cartridge-needle unit and comprises a solid circumferential neck; a circumferential foot interrupted in at least one point having inside and outside arcuate surfaces, the outside surface having thereon a circumferentially outwardly extending ring and the inside surface having thereon at least one radially inwardly extending shelf; and at least one leg connecting the neck to the foot. The collar provides improved safety reliability and thus reduces the susceptibility of health care workers to accidents, e.g., accidental needle strikes. In addition, the collar can be easily and economically manufactured, e.g., by conventional precision injection molding techniques.
