    Abstract: The present invention is to provide a double-pass type double monochromator having a high resolving power and an improved relative speed. To this end, there is provided an improved optical system in which the number of times light passes through the light dispersing element is doubled only with the provision of inexpensive reflector elements.

    Abstract: Symbols formed by marking a substrate with coded inks, the coding represented by the absence or presence in one or more levels of one or more photoluminescent components, are irradiated with ultraviolet light and the photoluminescence from the various coding components is projected through a dispersing agent, such as a prism or a grating, onto the sensitive surface of a television camera tube, such as a vidicon or orthicon, the output of the camera tube producing electrical pulses in each scan corresponding to the position of the various photoluminescent colors. The output can be read out on an oscilloscope or other readout device synchronized with the television camera electron scan. The presence of coding components are represented by pulses in corresponding positions and the height of the pulses can represent the level of component concentration if it is present in more than one concentration.

    Abstract: Coded inks are described having one or more photoluminescent components to represent different symbols which can then be read out by ultraviolet illumination. For example, six components can represent 63 different symbols by their presence or absence in a mark. A set of components is divided into two groups, for example, four and two in the case of six components. The four components are sufficient to generate 15 different symbols, for example, more than enough to represent 10 digits. These symbols are printed in four spatially separated small marking areas which may be circles or squares. Four digits, if arranged sequentially can represent the numbers 0 to 9,999; however, their sequence has to be known. The other group of components, for example two is incorporated into the marks to define the intended sequence of symbols regardless of the actual sequence in which marks are read.

    Abstract: A diffraction-grating-type monochromator apparatus having an improved apparatus for rotating the grating is described. The grating is fixedly mounted at the pivot of a follower arm which is pivoted by an arm bearing portion engaging the sloped surface of a wedge-shaped bearing member driven in a direction at an acute angle to the plane of the sloped surface. The wedge-shaped member is a solid wedge or a member in which the acute angle between the sloped surface and the direction of the drive is adjustable.

    Abstract: An optical dispersion element (e.g., a diffraction grating) is mounted on a scanning arm, pivoted on a first pivot pin carried by an auxiliary lever, which in turn is pivoted about a second fixed pivot pin. An (angled straight) edge of the scanning arm is cammed by a linearly moving driving pin so as to cause initially the scanning arm to pivot about the first, lever-carried pivot pin. A blocking mechanism inhibits rotative movement of the scanning arm relative to the auxiliary lever at a certain position, beyond which the scanning arm and the lever necessarily pivot conjointly about the second fixed pivot pin. The grating is therefore rotated at two different but related mathematical functions of the driving pin motion. A specific example obtains two different cosecant functions, thereby rotating a grating at two different angular rates (each of which is differently proportional to the wave number of the diffracted radiation leaving the grating in a fixed (in space) direction), thereby yielding a ''''scale change'''' during the grating rotative scanning.
