Abstract: ABSTRACT OF THE DISCLOSURE An elastomer-coated bias fabric having one tacky surface, for use in reinforcing power transmission belts and the like is disclosed herein. The fabric is a bias fabric having opposed surfaces, yarn or fiber bundles and interstices, and which are pre-impregnated with an elastomeric latex composition.  The fabric is provided with a layer of uncured non-carboxylated and non-tackified first elastomeric composition coated on both of the surfaces of the fabric and penetrating the yarn or fiber bundles and the interstices of the fabric, the layer having opposed surfaces and being substantially dry. That layer is overcoated with a layer of uncured tacky, carboxylated second elastomeric composition on only one of the surfaces thereof.  This fabric reinforcement is particularly advantageous because it provides secure posi-tional attachment between the coated fabric and the product base in prepara-tion for vulcanization.  A method for producing the coated fabric is also dis-closed.

Abstract: ABSTRACT OF THE DISCLOSURE      A method and a system are disclosed for measuring the baseline vector   between a pair of survey marks on the ground by radio interferometry using radio signals broadcast from the earth orbiting satellites of the NAVSTAR Global Positioning System (GPS), the radio signals broadcast by the satellites being double-sideband modulated with their carriers suppressed.  An antenna is positioned at each survey mark. The signals received by one antenna during a predetermined time span are separated into upper and lower sideband components.  These separate components are filtered, converted to digital form, and then multiplied together.  their product is analyzed digitally by means of correlation with quadrature outputs of a local oscillator to determine the power, and the phase relative to that local oscillator, of the carrier wave that is implicit in the double-sideband signal being received from each satellite.  Differences in Doppler shift are utilized to distinguish the carriers of different satellites, The signals received at the same time by the other antenna are processed in the same manner.  Thus, the powers and carrier phases of the signals from a plurality of satellites are measured simultaneously and numerical data representing the measurement results are obtained at each survey mark.  The measurements are performed in real time at each mark without reference to signals that are received at any other place and without knowledge of any of the coded signals that modulate the GPS carriers.  The data from the measurements performed simultaneously but independently at the two survey marks, once per second for a predetermined time span, are then processed together to determine the baseline vector that extends from one mark to the other.  Two methods of processing are disclosed.  In either method, an "ambiguity function" is computed which is a function of the measurement data and of a trial value ? of the baseline vector.  The vector space of ? is systematically searched to find the unique value of   that maximizes the computed function.  This value of ? is taken to be the desired determination of ?.  By using signals from a plurality of five satellites and a time span of about 5000 seconds, a baseline vector determination can be obtained by the method of the present invention with an accuracy of about 5 millimeters in each coordinate for a baseline length of about 100 meters.

Abstract: ABSTRACT     A centrifugal fan having the inner edges of the impeller blades (7) extending parallel to the impeller axis incorporates a circular damper plate (11) supported coaxially within the array of blades with its edge closely adjacent the inner edges of the blades, and movable in an axial direction so as to vary the useful width of the blades and thereby the flow rate. The damper plate, being separate from the impeller (2), may be supported in a non-rotatable manner and enables the fan to operate at an efficiency comparable with one having a radial vane damper, but is simpler mechanically as it requires only a single primary moving part.

Abstract: Abstract of the Disclosure A spectrophotometer is shown in which a deuterium lamp emits a plurality of frequencies of interest the beam passes through a filter for selecting the wavelength of the light desired to be incident onto the sample and then onto a beam splitting plate which diverts a relatively small fraction of the beam to a first reference photocell.  The remaining portion of the beam then is incident directly on a sample tube.  The sample tube may be so designed that its transparent walls form a lens focusing the beam on the sample to be tested.          The beam then passes through the further wall of the sample tube and is detected by a second testing photocell, the output of which may be compared to the output of the reference photocell to provide a signal indicative of the relative amplitude of the testing beam.  The reference photocell may be used to insure that the intensity of the beam incident on the beam splitter remains constant over time so that values output by the testing photocell may be comparable to measurements taken at a later time, without the use of a reference sample for calibration purposes.  A sample cell is provided which allows the use of the instrument of the invention in on-line applica-tions in high pressure systems.  A particularly preferred method of mounting the deuterium bulb is also shown.

Abstract: ABSTRACT OF THE DISCLOSURE           Method of vaporizing a solution containing a solvent and molecules of interest for detection or analysis, where the molecules of interest are non-volatile or ionic or thermally labile or a combination thereof.  The method involves partially vaporizing the solution in a heated passageway;  controlling the temperature of the solution in the passageway to maintain a predetermined degree of vaporization as the flow rate or solu-tion composition varies;  spraying the partially vaporized solution through a nozzle to form a thermospray of relatively dry particles entrained in an intense vapor jet;  controlling the downstream environment to prevent recondensation of solu-tion of the molecules of interest.  The remaining solvent carried by the relatively dry particles is vaporized by internal enthalpy.           Apparatus for the practice of this method is also disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE         In a binarizing system in which analog picture image signals formed by scanning a manuscript with a line sensor undergo quantization and digital picture image signals obtained by the quantization are binarized into signals representing black or white according to a predetermined threshold value, levels of a digital picture image signal of a picture element to be corrected and of a digital picture image signal of a picture element at least one main scanning line before the picture element to be corrected and positioned at the same position as the picture element to be corrected in an auxiliary scanning direction which is attenuated with each main scanning line or lines are compared.  Among the above two signals, a signal having a larger level at a given time is used as a reference signal showing the nature of tone of the manuscript.  When the level of digital picture image signal of the picture element to be corrected is smaller than the level of the reference signal, the level of the digital picture image signal is decreased.  In other cases, the level of the digital picture image signals is maintained.  By this operation, the nature of tone of the manuscript is emphasized,  Thus, accuracy of judgement in binarizing analog picture image signals is improved.

The other edge of the tarp is attached to a roller leaving a part of the roller bare so that the part can drop over the other side of the truck box just into a plurality of semi-circular half bearings defined by flat plates at right angles to the side of the truck box.   The bare roller thus can rotate in the half bearings to tighten the tarp.  Move-ment of the tarp is obtained by guide cables rolled up on to the roller in drum sections defined by flanges at the ends of the roller.  Each cable is attached to a spring mounted in a vertical tube to take up changes in length and to tension the tarp.  In one arrangement the roller is driven by a motor co-axial with the shaft with torque from the motor being communicated through a housing to a track along which the housing runs.  The housing includes a torque bar which can be bent in dependence upon the amount of torque with the degree of bending being mea-sured by limit switches which act to halt the motor.
