Abstract: ULTRASONIC DRIVE/SENSE CIRCUITRY FOR     AUTOMATED FASTENER TIGHTENING     Abstract:    An ultrasonic signal drive/sense circuitry is provided, which circuitry is adaptable to a variety of automated or manual fastener tightening operations.  This circuitry operates for measuring tension in a fastener as a function of change in time of flight of an ultrasonic wave.  A microcontroller directs the operation of circuit components to generate high amplitude, high repetition rate, drive pulses with these amplitude and repetition rate factors being electronically adjustable to compensate for fastening tool and fastener acoustical properties and tightening rates.  Software driven timing circuitry calculates, calibrates and adjusts pulse echo detection window width and center location and also optimum echo detection threshold.  This timing circuitry is implemented by digital techniques to measure pulse time of flight and incorporates analog interpolation of data between digital counts.  Sampling rates of the echo pulses are adjusted to tool speed.  An auto-calibration technique is implemented prior to each fastener tightening operation to overcome circuit errors and set detection window position and to optimize pulse voltage and echo threshold detection levels.  Time of flight data is selectably calculable from the initial ultrasonic pulse to the primary echo or successive reflections thereof.

Abstract: A b s t r a c t : (referring to Fig. 4) On  pallets loaded with several layers (tiers 11), relative-ly thin intermediate layers 13  made  of  cardboard  or  the like  are usually located between the tiers 11. These inter-mediate layers have to be removed after a tier 11  has been unloaded.  For  this  purpose,  a  suction lifter 16 with a suction plate 17 is provided,  which  lifts  and  discharges the  free  intermediate layer by means of a vacuum. To avoid undesirable relative displacements of the  stacked  articles (blank  stacks  12),  the suction lifter 16 is provided with holding-down devices  22.  These  devices  22  pass  through openings  23  in the intermediate layer 13 and come to abutt the blank stacks 12, such  that  the  latter  are  fixed  in place  when  the  intermediate  layer  13 is lifted. Profile members 31  are  arranged  on  the  suction  lifter  16  for further  securing  the  articles  (blank  stacks  12). These members  31  enter  cavities  32  formed  between   adjacent articles  (blank  stacks  12)  in  a  form-fitting  positive manner.

Abstract: ABSTRACT An  extruded hinge  with  a  multiplicity of bearing assemblies spaced along its length has a pair of abutting hinge leaves with mounting portions and pivot portions with convexly arcuate surfaces extending along their abutting edges and  intermeshing gear  teeth extending along  the length thereof.  The pivot portions have channels in their surfaces opposite the arcuate geared surface, and  the hinge leaves have pairs of axially offset, opposed cooperating cutouts extending through the pivot portions.  These cutouts provide a center portion in which the cutouts are aligned and recesses at the axial ends thereof in opposite hinge leaves.   An elongated lateral bearing member has a cavity therewithin which receives the pivot portions, and it has opposed flanges at its free ends, which extend into the channels of  the pivot portions to lock the hinge leaves in assembly.  In each of the cutouts is a bearing block with a body portion disposed in the center portion of the cutouts and axially projecting portions at each end disposed within the recesses defined by the cutouts.  The bearing block has channels along its sides which seat the bearing member flanges.  Bearing caps are disposed in the cutouts between the ends of the body portion of the bearing block and the adjacent pivot portions of the leaves, and they are engaged with their respective pivot portions and pivotable therewith.

Filed: 1992-02-24
Abstract: ABSTRACT OF THE DISCLOSURE      A pseudo-luminous panel has a substrate and a thin film optical color filter formed all over the main surface of the substrate with or without a reflecting film interposed therebetween.  The main surface of the substrate is formed by obliquely downward and upward band-like surface portions alternately arranged side by side in a vertical direction. Obliquely downward band-like surface portions of the reflecting film, formed on the obliquely downward band-like surface portions of the substrate, or the obliquely downward band-like surface portions of the substrate are each a smooth reflecting surface. Obliquely upward band-like surface portions of the reflecting film, formed on the obliquely upward band-like surface portions of the substrate, or the obliquely upward band-like surface portions of the substrate are each an irregular or uneven reflecting surface.    With the pseudo-luminous panel of such a structure, it is possible to prevent that a pattern on the panel is too dazzling in the daytime and too dark at night to recognize in a predetermined hue when the panel is disposed above ground outdoors.
