The present invention relates to new delivery systems for cyclopropene compounds of a cyclopropene compound generator comprising at least one substrate, a material containing at least one cyclopropene compound and a release agent whereby at least one side of one substrate is coated with the material containing at least one cyclopropene compound and wherein when the material containing at least one cyclopropene compound is exposed to the release agent, a gaseous cyclopropene compound is released. The present invention also provides methods to release a cyclopropene compound from such a generator to deliver a cyclopropene compound to plants, fruits, flowers or vegetables to inhibit an ethylene response in the plants, fruits, flowers or vegetable.

Delivery systems for cyclopropene compounds

An apparatus and method are disclosed herein for processing exposed photosensitive self-developing film in a single use camera.

Single use camera employing self-developing film and method thereof

A film assemblage of the self-developing type which has a pair of upper and lower carrier sheets in juxtaposed relationship to one another. A pair of openings is provided in each of the carrier sheets. A photosensitive sheet and a positive receiving sheet are joined to outer surfaces of the upper and lower carrier sheets; respectively, so as to cover the respective openings. The pair of upper and lower carrier sheets is fixedly joined together in overlapping relationship, whereby the photosensitive and receiving sheets are in superimposed and spaced apart relationship thereby forming, in combination, an image area of the film.

Simplified self-developing film assemblages and methods of making the same

The present invention relates to a hand-held diagnostic testing system and method employing apparatus that can effect a chemiluminescent reaction and record the same on photographic film.

Apparatus for performing diagnostic testing

A postage stamp assemblage wherein an indicia bearing element containing a photographic film unit is covered by an overlay sheet containing a transparent zone, allowing the photographic film unit to be visible. The postage stamp assemblage contains machine readable indicia and postage indicia.

Self-service postage stamp assemblage

A diagnostic device adapted to retain a fluid sample to be analyzed until it is desired to initiate the analytical test is described. The device includes a deformable material layer, a well for holding a fluid sample, a porous material and a diagnostic assay element.

Diagnostic assay device

The present invention provides a method of providing a self-contained processor having a luminescent testing material capable of generating a read-out signal in response to contact with a reagent of interest in a test sample. In an alternate aspect, the present invention also provides a portable and self-contained diagnostic assay system for detecting and recording the presence of a luminescent signal generated by a reaction between a luminescent testing material and a reagent in a test sample on a self-developing film assemblage.

Diagnostic assay system and method having a luminescent readout signal

The present disclosure relates to several embodiments in which different self-developing film formats are constructed in order to permit easy operator separation of the pod and trap from adjacent integral film units.

Photographic film assemblages of the self-developing type having removable portions

There is described a self-developing film unit which has a photosensitive member and an image-receiving member and wherein one outermost surface of the film unit comprises a support layer carrying a layer of a releasable material and a layer of an adhesive material. After an image is formed in the film unit by photoexposure of the photosensitive element and photographic processing of the exposed photosensitive element, the support and releasable material layer can be removed and the film unit or the image-receiving element, as the case may be, adhered to a surface for viewing of the image.

Self developing-film unit

An imaging apparatus and method for use with a film assemblage strip of the self-developing type including an active matrix LCD for providing an area imaging means for exposing the film assemblage at an exposure station, wherein indexing the strip is accomplished by having indexing means of the strip selectively cooperate with pressure applying means, such that when one of the frames on the strip is processed the next successive film frame is simultaneously advanced to the exposure station to be exposed.

Imaging apparatus and method

A diagnostic assay device comprising a housing assembly and an image recording material housed therein that is exposed by a luminescent read-out signal generated by a luminescent activity triggered in response to displacement of a liquid carrier assembly carrying an analyte of interest with a reservoir containing an assay solution.

Diagnostic assay system and method

A camera according to the present invention includes a first cavity to accommodate conventional film material having multiple frames, each frame having a corresponding indicia disposed on the conventional film material to identify the corresponding frame and a second cavity to accommodate self-developable film material having multiple image forming portions, each image forming portion having a corresponding indicia disposed on the self-developable film material to identify the corresponding image forming portion and a corresponding frame of conventional film material. The camera further includes a light path for exposing simultaneously one of the multiple frames of the conventional film material and one of the multiple image forming portions of the self-developable film material.

Dual exposure photographic apparatus and method of operating same

A photographic film assemblage comprising: a plurality of photographic elements connected in end-to-end fashion and a separable portion connected to and between adjacent pairs of the elements is disclosed wherein each of the separable portions has at least a weakened segment that separates when pulled and allows adjacent pairs of the elements to separate. At least one layer is connected to one of the elements so as to extend generally longitudinally along the film assemblage and be in overlying relationship to at least the weakened portion. The layer is constructed and sized to reduce friction on the film assemblage in operative relationship to the pressure applying members to thereby enhance separation of the separable portions and the elements.

Self-developing film assemblage

An imaging apparatus and method for singulating individual film units from a self-developing integral film which units are carried serially in spaced apart relationship to each other are provided. The imaging portion of each unit is stiffer than associated leading and trailing portions whereby the leading portion beyond the pressure applying assembly is severed, while the severed flexible portion is diverted toward a receiving area therefor as the film unit advances along a path. Thereafter, provision is made for severing the strip along a trailing edge adjacent the imaging portion as the imaging portion advances along the path towards the exit; and, diverting the relatively flexible trailing portion from the path to a receiving area therefor as the film unit.

Imaging apparatus and method of handling film

An improved self-developing film unit comprising: a processing fluid supply including a rupturable reservoir of processing fluid; an image recording assembly of the self-developing type including first and second overlying layers one of which is exposable to form a latent photographic image, and a spacer connected to and between the first and second layers for providing a processing space therebetween for allowing processing fluid to pass therethrough; a fluid trap at a trailing end portion of the film unit for collecting excess processing fluid traveling through the processing space; a first fluid-tight coupling device including a fluid passage for fluidically coupling the reservoir to a leading end of the processing space for allowing processing fluid from a ruptured reservoir to be introduced into the processing space and initiate processing of the latent image; and, second fluid-tight coupling device including a fluid passage for fluidically coupling a trailing end of the processing space with the trap for allowing processing fluid to enter into the trap; the image recording assembly comprises a photosensitive layer, an image receiving layer in overlying and coextensive relationship to the photosensitive layer; the image receiving layer and the photosensitive layer being of the integral diffusion transfer type; and, the spacer comprises a pair of spaced apart and generally parallel elongated rails coextensive with and adjacent opposed marginal edges of the layers.
