Abstract: Abstract of the Disclosure An automatic document sorter particularly suit-able for sorting retail store coupons employs a plurality of relatively coarse sorting processes in cascade.  The sorting processes sequentially sort the documents according to predeter-mined properties of the document, including codes, such as bar codes or the like; physical properties, such as size, thickness, color, reflectivity and opacity; the characteris-tics of the inscriptions on the face of the document; and any uniquely marked areas of the document face.  Such a sorting hierarchy permits the documents to be sorted rapidly by reducing the precision required in each sorting step.  The hierarchy also permits each document to be classified during each sorting step as falling into a particular class of documents in order to simplify subsequent sorting steps.  If a property uniquely identifying the document is found during any one of the sorting steps, the processing is terminated at that point without completing the subsequent sorting steps.

Abstract: Abstract of the Disclosure An ultrasonic detection system uses an array of ultrasonic transducers that are uniformly closely disposed relative to each other so that their active surfaces for transmission (and reception) are maintained on a straight or curved line.  These transducers form radiation (and reception) beams each in a specific direction.  Beam orientation is accomplished by selecting a group of transducers from the array and applying appropriate phase-shifts to the signals transmitted to each transducer or to the signals received from each transducer.  Shields are maintained between adjacent pairs of transducers for suppression of sidelobes in the beam pattern.

Abstract: ABSTRACT This invention relates to a method and apparatus for investigating a rod-like body which is anchored in a surrounding material and which has an accessible end, for determining the state of the anchorage of the body and its length.  It has long been known in the art that elastic oscillations of a multiplicity of different wave types can be used to determine the state of boltsand other anchors.  However, there is a problem in the present art in that the oscillations are highly dampened.  The present invention provides the advantage of having oscillations with a much lower damping effect and which do not pro-pagate in bore hole mud.  Transient elastic oscillations are excited in the accessible end of the body.  The oscillations comprise a flexural wave causing a deformation of the body varying with respect to amplitude and phase over the cross-section of the body.  The flexural wave propagates in the longitudinal direction of the body and is partially reflected at discontinuities of the body and/or the anchorage.  Transient elastic oscillations comprising flexural waves reflected at such discontinuities and returning to the accessible end of the body are received and detected.  The position and magnitude and/or type of at least some of the discontinuities are estimated with the aid of time-position and amplitude of the reflected flexural waves.  Discontinuities of interest are the beginning and end of anchorage, the end of the body and possible cracks or fractures in the body and/or its anchorage.  The method and the apparatus are primarily intended for in-situ investigation of concrete-bond rock anchors (bolts) although the method and apparatus can be used for at least partially investi-gating other anchored rod-like bodies.
