  • Apparatus for guiding a vehicle
    Patent number: 4458775
    Abstract: The invention relates to apparatus for guiding a vehicle as it moves, of the kind comprising a detector (12) sensing deviation of the heading of the vehicle relative to a pre-determined direction and producing an electrical deviation signal, a hydraulic piston and cylinder device (16) steering the vehicle wheels (2) and control means (15) responsive to the deviation signal.The technical problem is to provide apparatus of this kind whose operation is progressive and avoids systematic hunting.In accordance with the invention, the detector produces a deviation signal which is proportional to the deviation of the vehicle heading from the pre-set direction, and the servo-valve provides progressive control as a function of the deviation signal.

  • Apparatus for filling a high temperature liquid into a biaxially oriented, saturated polyester bottle, a device for cooling said bottle
    Patent number: 4450878
    Abstract: A biaxially stretched molded bottle is forcibly cooled by having its outer surface contacted with a cooling fluid such as cold water or gas to avoid its deformation by the heat of a liquid poured into the bottole and elution by such heat of any constituent of the material from which it is molded, when the bottle is a molded product of a saturated polyester resin, particularly polyethylene terephthalate, which has poor heat resistance like bottles of other synthetic resins, and is filled with the liquid which is heated to a high temperature for sterilization purpose only when it is filled into such a bottle and which is allowed to return to room temperature or cooled. When the liquid is poured into the bottle through its open neck, the cooling fluid supplied for cooling the bottle is prevented from flowing into the bottle through its open neck and mixing impurities into the liquid in the bottle.

  • Detector for use in optical measuring instruments
    Patent number: 4444499
    Abstract: A detector for use in optical measuring instruments such as a double-beam spectrophotometer, comprising a photoelectric element having a photosensitive surface and a beam mixer disposed adjacent the photosensitive surface for causing each of two alternate light beams to be projected evenly and uniformly onto the photosensitive surface of the photoelectric element thereby to eliminate errors which would otherwise be caused in the result of measurement due to local difference in sensitivity of the photosensitive surface of the photoelectric element. The beam mixer comprises a symmetrical pair of light diffusing plates so arranged as to form a roof-shaped configuration and a tublar body having one end opening closed by the pair of light diffusing plates and the opposite end opening closed by the photosensitive surface of the photoelectric element.

  • Method and apparatus for real time detection of faults in industrial objects
    Patent number: 4433385
    Abstract: Method and apparatus for the detection of faults in industrial objects and signalling such faults to handling apparatuses. According to the invention, the image is taken of a sample object by a television camera or other sensing device; the image is digitized and stored in a frame memory. The digitized sample (standard) image is then divided into small areas, for each of which the square root of variance (standard deviation) for the luminance levels of dots belonging to each area is calculated and stored. The same operations and elaborations are followed for each object to be checked and the obtained values are compared with those of the sample. When the differences thereof are above predetermined thresholds, an output signal is generated for distinguishing the fault and generally the faulty object and for controlling a handling apparatus for the objects.

  • Implantable glucose sensor
    Patent number: 4431004
    Abstract: A method and apparatus for more accurate measurements of the glucose content in body fuids by sensing the absolute level of oxygen concentration in the fluid and correcting the output differential measurement indicative of the glucose content in the fluid according to the absolute level of oxygen.In the two electrode systems known to the art, the unaltered oxygen electrode of the electrode pair may be employed to read the absolute level of oxygen concentration and in addition, function to establish the difference in oxygen concentration caused by glucose oxidation.In view of the fact that temperature may vary, a thermistor may be included in the electrode system to make temperature corrections for reason that the absolute oxygen reading from either a polarographic or galvanic oxygen electrode is extremely sensitive to temperature and the rate of glucose oxidation is temperature sensitive.
