Abstract: MICROVECTOR CONTROL FOR EDGE AND JOINT FOLLOWING ABSTRACT OF THE DISCLOSURE        An industrial robot is controlled to move by increments and approximately track an edge or a joint. A structured light pattern such as two parallel light bars is projected onto the workpiece and the scene is imaged by a visual sensor.  Information derived from the image is used to compute move vectors.  The navigation algorithm is based on extracting and computing the next move vector from the visual scene while the current move vector is being executed.  The positioning system of an arc welding robot approximately follows the joint to be welded;  the computed microvectors specify the direction and distance the positioning system moves.

Abstract: ABSTRACT OF THE DISCLOSURE   APPARATUS FOR CREASING FOLD LINES IN A   SHEET OF CARDBOARD   Apparatus for creasing fold-lines in a sheet of cardboard, especially for a lid e.g. for a tin plate stack, has an upright support surface for the cardboard sheet and a conveyor for bringing the sheet in an upright position against the support surface.  Adjacent the support surface is a resilient track, and a pressing wheel having a tapered periphery forming a creasing edge is arranged to move along said track so as to form a creased fold line in a front side of the sheet when the sheet is interposed between the wheel and the track.  A suction pad engages and picks up the sheet on the support surface and is movable horizontally and vertically so as to bring the sheet into the desired position for creasing on the said track and is rotatable so as to rotate the sheet in its plane in order that fold lines at angles to each other can be creased in the sheet. Creasing tongs are arranged to engage the rear side of the sheet to form creases therein.

Abstract: ABSTRACT                  "Strain Transducers"       A strain transducer of the kind in which a plug is inset into a workpiece surface requires an accurate interference fit with a drilled hole.  One method proposes an oversize hole (12) which first receives an annular insert (14) in whose aperture (15) the trans-ducer plug is a precision fit.  The outer cylindrical surface of the insert has axially parallel serrations (16) which bite into the sides of the hole.  Another method also has an oversize hole (22) whose mouth is constricted by a cylindrical punch (25) around a precision mandrel (24) which is then replaced by the transducer plug (28).          Serrations (35) may alternatively be provided directly on the transducer plug (32), which can then be driven into a drilled hole (36) of only approximate accuracy.

Abstract: INVENTOR:   JORIS SCHR?DER INVENTION:  GROUP CONTROL FOR ELEVATORS WITH DOUBLE CABINS                   ABSTRACT OF THE INVENTION           With this group control the allocation of the individual cabins of double cabins of an elevator group to stored storey calls can be optimized with respect to time, and newly arriving storey calls can be immediately allocated.  A computer containing a microprocessor is provided for each elevator and computes the service costs corresponding to the waiting times of passengers for each cabin of the related double cabin with reference to each storey.  The service costs are reduced if calls of identical direction are present for a storey for which the computation is carried out and a directly adjacent storey and/or there is coincidence of cabin calls and such storeys.  The service costs for both cabins of a double cabin are compared and the lesser costs are stored in a cost storage of the relevant elevator.  During a cost comparison cycle the service costs of all the elevators are compared on a storey-to-storey basis by means of a comparison device, and an allocation instruction is storable in an allocation storage of the related elevator with the least service costs.   The allocation instruction designates that storey to which the relevant cabin of the double cabin is optimally assigned with respect to time.

Abstract: ABSTRACT     Leather sheets having desired grain pattern are mounted on a roller with edges abutting.  Onto the surface of the grain pattern a sillicone synthetic resin is applied as a uniformly thick coating with a coating knife as the roller rotates.  The resin is hardened into a matrix.  It is then peeled off the grain pattern.  The grain pattern in the matrix is interrupted where the leather sheets abutted.  The matrix is placed with the pattern outward on a roller whose diameter pretty much matches the diameter of the embossing roller to be produced.  The surface of a tubular thermoplastic film is embossed by contact with the cylindrical matrix under heat and pressure.  The embossed surface of the thermoplastic film is once again overembossed under heat and pressure in the areas along the abutting edges of the natural grain pattern on the roller, so that an endless positive impression without seams in the grain's pattern is produced.  Another layer of sillicone rubber is applied to the positive impression, which layer is vulcanized into a matrix which is peeled off the positive form and adhered to the circumferential surface of the embossing roller with the negative side out.  With this embossing roller a natural leather grain can be embossed on a thermoplastic film without the appearance of discontinuities at the abutting edges.

Abstract: ABSTRACT OF THE DISCLOSURE     In a communication network in which a plurality of information processors are coupled to a communication medium through medium attachment units (MAUs), a pilot signal generator sends a pilot signal of a reference level to a predetermined point of the communication medium.  Each MAU has a gain controller to control the gain of a transmission amplifier.  This gain controller transmits a test signal to the communication medium through the transmission amplifier.  The gain of the transmission amplifier is adjusted in accordance with the reception level of this test signal such that the reception level of the test signal becomes equal to the reception level of the pilot signal.  Each MAU is pro-vided with a random number data generator and sets the transmission time slot of the test signal in dependence on random number data to prevent simultaneous transmis-sion of test signals from MAUs.

Abstract: Eddy Current Flaw Detector Method and Apparatus Abstract Eddy current test apparatus of the type that gener-ates eddy currents in an object and that senses flaws or defects by sensing changes in the induced eddy current. Two differential encircling coils surround a moving workpiece moving relative to said coils.  One of the two test coils has an enclosed tubular pathway forming a loop adjacent to the coil.  A steel ball is placed in the enclosed tubular pathway and is air driven through the pathway so that it continuously revolves in close proximity to the coil.  The steel ball disrupts the magnetic field flux generated by the test coil in the workups.  This disruption modifies the eddy current in the workpiece which in turn induces a well defined output signal in the test coil.  In an alternate and preferred embodiment, two ferrite objects are rotated near the two encircling coils to disrupt the eddy cur-rents produced by both coils.  The ferrite objects are radially offset so that they do not disrupt the magnetic fluid near a flaw at the same time.

Abstract: Abstract of the Disclosure A  low-pass  filter  for  digital  bearing  data  from  an aircraft  navigation  receiver  in  which  the  filter  time constant is set to a high value when the receiver bearing data  exhibits  characteristics  of  a  noisy  signal  received from a distant station where the bearing from the aircraft to the station can change only at a slow rate and in which the filter  time constant is set to lower values for less filter  delay  when  the  receiver  bearing  data  exhibits characteristics  of  a  less noisy  signal  received  from  a nearer station where the bearing from the aircraft to the station can change at a higher rate.  Receiver bearing data for  a  current  sampling  interval  is  compared  to  filtered bearing data for a previous sampling interval to determine change in magnitude of the difference.  Such difference for a  current  sampling  interval  is  compared  with  a  similar difference for a previous sampling interval for change in algebraic  sign.   Filter  time  constant  is  set  to  higher values when difference magnitudes are small and sign changes are  frequent  and  is  set  to  lower  values when difference magnitudes are larger and sign changes are infrequent.
