    Abstract: In an X-ray photography apparatus of this invention, an X-ray tube and an image receiving device are attached to two tilting members which are each rockably supported on the distal end portion of a traveling support frame telescopically protruding parallel to a horizontal main axis from a rotating base rotating about the main axis. The position and the angle of X-raying of the X-ray tube may be set as desired by suitably selecting the length of extension of the traveling support frames and the angle of rotation of the tilting members. It is also possible to set as desired the position and direction of an image receiving device for receiving an X-ray beam transmitted through a subject or a patient.

    Abstract: An optical temperature gauge using a semiconductor crystal (12) having a band-edge shift property which is temperature dependent. An external narrow band light source (10) provides optical excitation through an optical fiber (11) and light energy thus passed through the crystal (12) is conveyed by a second optical fiber (13) to a light-to-electric transducer (14) at an external location, the crystal (12) thereby being locatable in cryogenic or other systems, to provide remote read-out. The light wavelength is varied (scanned) in a repetitive pattern in source (10), the instantaneous wavelength passing over the band-edge wavelength during each cycle of the scan. The timing of the crossover is related to the temperature of the crystal by electronic means (15 and 17). Several alternative elements of instrumentation are disclosed.A variation in the basic measurement apparatus is also disclosed, in which the band gap voltage of a light source (10) such as a laser diode is evaluated at the time of band-edge crossover in the crystal (12) and converted to a temperature value.

    Abstract: An improved method and apparatus for measuring the moisture contained by a moving sheet of web material includes a water simulating filter in a typical dual wavelength moisture gauge which provides transmission ratios. The relationship between the change of ratios of various samples of the material with different moisture content with the change of the filter ratios when various layers of moist dirt are placed in the gauge transmission path is used to provide a corrected transmission ratio from which water weight can easily be determined. The method is also applicable to polymer coatings or similar substances.

    Abstract: The propagation in an optical fiber of an incoherent optical signal pulse containing a moderate spread of optical wavelength carrier components, such as supplied to the optical fiber by a light emitting diode (LED) source, results in a broadening (distortion) of the optical output signal emerging from the fiber. This distortion is caused by the fact that different optical wavelengths propagate at different velocities through the fiber material, that is, by the dependence of refractive index upon wavelength (material dispersion); and also by the fact that different optical modes propagate at different velocities (mode dispersion). In order to compensate for such distortions, a semiconductor charge carrier drift delay line is located in the path of the optical radiation emanating from the fiber. Advantageously, this semiconductor delay line is depleted of bulk majority charge carriers by means of a reverse voltage bias and is terminated by a charge carrier detector having an inherent gain (such as an avalanche diode or a transistor). The delay line is arranged such that the time delays of different wavelengths or modes in the fiber are compensated by the different drift time delays of the charge carriers generated by the different wavelengths or modes absorbed at different locations in the semiconductor delay line. In the case of mode dispersion compensation, the s

    Abstract: Apparatus for avoiding ambiguity in a quantised signal representing a pattern which is scanned by an optical detector. The apparatus operates to scan the pattern to be represented and to produce a quantised signal each quantum of which represents the major colour in each scanning element of the pattern scanned. Sampling means are provided which sample the binary signal produced by the scanning means at a rate higher than the rate at which the signal is ultimately to be quantised and the output from the sampling means controls a gating circuit which operates to prevent the signal representing the pattern from changing from a representation of one colour to a representation of another unless a predetermined number of the samples all represent one colour. This avoids any indeterminacy in the quantised signal at colour junctions where there are two or more colours present in an element being scanned, and no colour is sufficiently predominant for the detectors to unambiguously provide an output representing only that colour.

    Abstract: A method and device for generating spectral radiation characteristic of a liquid sample. An electrical voltage is applied to a body of conductive liquid, the voltage being in excess of the breakdown voltage of the vapor state of the liquid and causing a current sufficient to raise the temperature of the liquid to cause the liquid to vaporize and form a bubble. The bubble formed is sufficiently restricted so that the potential across the bubble can rise until electrical breakdown and an electrical discharge only across the bubble occurs.

    Abstract: A flow-through cell analyzer using a compensating photoelectric circuit indicating the ratio of light passing through a measuring cell and light impinging on the cell. A source of light projects a beam which is controlled, for example, by different filters and which is split into two equivalent beams going to respective photoelectric cells the outputs of which are compared, one of the cells providing a reference voltage which is kept constant by varying the intensity of the light source or by the use of filters or diaphragms.

    Abstract: In a monochrome sensor, a sensor unit is covered with a protective film, and a light-transmitting organic film is formed on this protective film. Consequently, ripples in the spectral sensitivity characteristics are reduced. Even if the positions of the peaks and valleys of these ripples vary due to variations in the thicknesses of the protective film and the organic film or due to effective variations in these film thicknesses caused by the difference in the incident angle of light, a variation in the sensitivity at a given wavelength is small. This results in a small variation in the wavelength at which the maximum value of the spectral sensitivity is obtained and a small variation in the sensitivity derived from the difference in the incident angle of light.

    Abstract: Apparatus for gathering data about a plurality of chemical or physical conditions, e.g. on industrial plants, utilizes a plurality of passive optical sensors. Light for the sensors is provided by a common broadband source, and distributed by an optical fiber from which light of a selected color is withdrawn for each sensor in turn, the color selected for each sensor being different from that selected for the other sensors. Each color is modified by its respective sensor as a function of changes in the conditions applied to the sensor, and all the modified colors are conveyed along a common data bus to be demultiplexed and the data displayed. The colors may be supplied by the data bus to detection means simultaneously or sequentially. Passive optical sensors avoid electrical interference and incendiary risks due to electrical sparking, and color multiplexing avoids difficulties associated with other forms of multiplexing in plant environments.
