    Abstract: A method of “reading” the result of an assay effected by concentrating a detectable material in a comparatively small zone of a carrier in the form of a strip, sheet or layer through the thickness of which electromagnetic radiation such as visible light is transmissible, wherein at least a portion of one face or the carrier is exposed to incident electromagnetic radiation which is substantially uniform across the entire portion, the portion including the small zone, and electromagnetic radiation emerging from the opposite face of the carrier is measured to determine the assay result. Preferably the radiation is diffuse light.

    Abstract: An assay result reader, for use in conjunction with an assay device comprising a porous liquid-permeable carrier in the form of a strip or sheet through the thickness of which electromagnetic radiation is transmissible, the carrier including a detection zone in which an assay result is revealed by specific binding of a detectable material directly or indirectly to a binding agent immobilized in the detection zone, detection of the detectable material being effected by determining the extent to which electromagnetic radiation transmitted through the thickness of said carrier is attenuated by the presence of the detectable material bound in the detection zone.

    Abstract: A machine is disclosed for inspecting the profile and wall of a bottle which is delivered by a conveyor sequentially to two inspection stations. A pair of light sources, when fully illuminated, define two images of the bottle on a CCD camera image, so that the wall can be inspected. Portions of the light sources are darkened so that two different images of the bottle will be imaged on the CCD camera image so that the profile can be inspected.

    Abstract: A portable, hand held reflectometer which employs at least one blue light emitting diode for measuring the optical brightness of an opaque material, such as a stack or pad of paper is disclosed. A brightness measuring reflectometer which employs two blue light emitting diodes arranged so as to substantially reduce measured brightness variations caused by changing the orientation of the reflectometer relative to that of the fibers contained in a fibrous material such as paper whose brightness is to be measured is also disclosed. An ultraviolet light source such as a fluorescent lamp is also employed for measuring the brightness of paper or other materials which contain ultraviolet light excitable blue wavelength emitting substances. An electronic circuit for operating the reflectometer is also disclosed which employs a negative feedback circuit for maintaining the intensity of the ultraviolet light source at a relatively constant level.
