Abstract: ABSTRACT OF THE DISCLOSURE   An apparatus for analyzing line sequential binary data generated by scanning a printed circuit board with a scanning laser apparatus is disclos-ed.  The circuit board contains conducting strips on an electrically insulated substrate.  The conductors can be characterized by the number and the locations of their corners and by their widths and by the widths of the substrate ocur-ring between parallel and spaced apart conductors.  The line sequential data when viewed together forms a two dimensional image array of the circuit board and the two dimensional array contains information about the conducting corners, widths, etc.  The line sequential binary data is first smoothed by smoothing circuits to eliminate errors due to noise, scanning equipment tolerances, etc. Then the smoothed data in line sequential format is transmitted to a corner recognition and pairing circuit where the corner features of the conductors are recognized.  Because of digitizing errors, a corner feature often appears as two, three or more vertically and/or horizontally adjacent corner pairs. The excess corners are eliminated by the corner recognition and pairing circuit. At the same time, a line/space width error detection circuit portion of the apparatus examines the widths of the horizontal and vertically directed conducting strips and the spaces between them.  If any of the conductors or spaces fall below a predetermined minimum over a predetermined length of the conductor or strip an error signal is generated.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention is concerned with a method for monitoring furnace installations, comprising the steps of (a) passing a flow of gas through a heat-exchange zone where heat is removed from the flow of gas and the tempera-ture thereof is reduced to between 200 and 300°C, (b) measuring the oxygen partial pressure in the flow of waste-gas at the reduced temperature by using a sensing device which responds to the oxygen partial pressure in the waste-gas and which produces an output-signal as a function of the oxygen partial pressure, (c) detecting an abrupt change in the sensing-device output-signal occurring at the transi-tion from super-stoichiometric to sub-stoichiometric com-bustion, and vice-versa, and (d) producing at least one switching and/or warning signal as a function of the abrupt change in the output-signal from the sensing device, the switching or warning signal serving to actuate a shut-off element or alarm.  The method of the invention permits simple safety-monitoring of jacketed radiant-heat tubes and recupera-tor-burners, by means of a sensing device responding to the oxygen partial pressure in the waste-gas.  Unsatisfactory combustion-conditions, flame-outs with the gas-supply open, leaks in closed gas solenoid-valves and damages, e.g. cracks in the jacket of the radiant-heat tube, are all reliably detected and switching signals for shutting off the media-supplies and returns of the jacketed radiant-heat tube, or for releasing a warning, are produced.

Abstract: ABSTRACT          This specification  discloses  a  resilient  wheel suspension  (10)  wherein  a  wheel  (11)  is  rotationally mounted  upon  an  axle  (12)  and  the  axle  is resiliently suspended  with  respect  to  a  mounting  plate  (14).   The resilient suspension includes an elastomer disk (60) which is coupled along one major surface to the axle  (12)  and along the other major surface to the mounting plate.  The axle is coupled eccentrically to the elastomer disk so that the  axle axis  is  offset  from  the  central  axis  of  the elastomer  disk.   Lateral movement  of  the  axle  causes  a shear to be applied in the elastomer disk.  The eccentric mounting provides increased suspension travel, more ground clearance and more wheel mounting clearance with respect to a concentric mounting.   The suspension can have nonlinear characteristics by having  a plurality of elastomer disks (60, 61, 62) and metal disks (55, 56, 57, 58) with central openings for passing the axle and successively coupled to adjacent  disks  between  a  coupling  to  the  axle  and  a coupling to the mounting plate.   The size of the opening diameter increases in successive disks going from the disk adjacent to the axle to the disk adjacent to the mounting plate.   Successive  disks  are  also  mounted  eccentrically with respect to the axle.

Abstract: APPARATUS FOR MEASURING           VISCOSITY AND ELASTICITY OF A FLUID                 ABSTRACT OF THE DISCLOSURE          Disclosed herein is a torsion tube apparatus for making on-line measurements of the viscosity and elasticity of a fluid.  The apparatus includes a housing member, an outer cylinder having one end rotatably mounted with respect to the housing member, and a motor for rotating this outer cylinder.  An elongated torsion tube is mounted concentrically within and spaced from the outer cylinder and has one end fixed to the housing member, with its other end freely disposed within the cylinder for torsional movement with respect to the fixed end.          Therefore, an annular void is defined between the tube and cylinder.  Fluid may be introduced through a conduit into the interior of the cylinder for flow therethrough and discharge therefrom, such that rotating motion of the fluid caused by rotation of the cylinder exerts a torsional force directly on the outer surface of the tube.  A torsion indicating shaft extends concentrically through the tube, having its one end fixed to the free end of the tube.  An indicator is fixed to the other end of the shaft.  Accordingly, torsional force on the tube provides the sole source of rotative movement of the shaft that is detected by the indicator.  The assembly provides a smooth axial path for the fluid which flows through the annular void between the outer cylinder and tube.

Abstract: ABSTRACT OF THE DISCLOSURE   A moisture-measuring device for measuring moisture of the ambient on one side of a solid wall comprises a piezoelectric crystal sonically coupled to the wall on a surface thereof facing the one side. A capacitor or other moisture sensitive impedance means is connected to the piezoelectric crystal over a network which is operable to provide a response indicative of the impedance of the capacitor upon excitation of the crystal at the resonant frequency of the circuit. The capacitor comprises at least two spaced plates which are exposed to the ambient. Change in moisture in the ambient thus causes change in capacitance of the capacitor. By sonically exciting the piezoelectric crystal from an opposite side of the wall, a measure of change in resonant frequency of the network can be made. This measurement is related to the moisture content of the ambient.

Abstract: ABSTRACT OF THE DISCLOSURE    A wave motion compensator for a marine winch, in which the tension on the winch rope is maintained sub-stantially constant while the load on the rope moves relative to the winch.  This constant tension is main-tained by controlling the winch drive motor so that the movement of the winch rope matches the movement of the load without substantial lag.  The control is provided by a computer which repeatedly monitors the movement of the winch rope and, by comparing this input data and standard sea state data, predicts the relative movement of the load and the winch at a time in advance of the time the predic-tion is made at least as long as the lag time of the winch system.  The computer then issues appropriate commands to the winch drive motor controller.  In marine applications involving the lifting or lowering of loads, the computer is also used to determine the optimum time for initiating lifting and completing lowering of the load, and to automatically perform these operations.
