Title: Ultrasonic testing method
Inventor: FERREIRA NICHOLAS C
IPC: G01N29/34
Filed: 1989-02-20
Granted: 1992-12-22
Abstract: ABSTRACT OF THE DISCLOSURE        An ultrasonic sound echography technique is disclosed in which echo-masked zones of the workpiece are reduced by utilizing particular orientations of the beam of ultrasonic sound relative to formations in the workpiece.  Echo-masked zones result from formations in the workpiece which reflect the ultrasonic sound waves back to the probe and therefore mask the much smaller echoes from anomalies, if any, in the workpiece.  Instead of the conventional orientation of the beam, in which the scanning plane in which the beam lies is oriented perpendicularly to formations, the scanning planes are selected so as to be nonperpendicular with respect to such formations and to minimize the amount of masking echoes from the formations.

Abstract: A method and apparatus for applying sleeve labels to product containers including a label gripping assembly for engaging a label and pulling it onto a product container and a web positioner for adjusting the position of a next-to-be-applied label prior to engagement by the label gripping assembly.  During a label applying cycle, the label being applied is severed from the web along a line of weakness interconnecting the end most label with the next-to-be-applied label, after the next-to-be-applied moves to a predetermined position located downstream of an initial position.  The web positioner reverse feeds the web until the leading edge of the next-to-be-applied label retracts to the desired initial position.  The web positioner includes a driven roll and a nip roll that is movable towards and away from the driven roll by an actuator.  The driven roll is continuously rotated and the nip roll is driven into frictional engagement with the driven roll in order to effect web retraction.

Abstract: ABSTRACT    This invention relates to an apparatus for encoding and transmitting an image.  The apparatus includes a vector quantizer.  A quantization preprocessing circuit is used for subsampling an image signal, for thinning out pixels from the image signal according to a pixel ratio, and for generating from the pixel signal an n-dimensional vector.  A group of input buffers are used to store each input vector in a sequence for quantization processing and for repetitiously reading the input vector at an interval of the processing period.  A vector output circuit is used to prepare the output vector corresponding to a probability distribution of the input vector and for selecting and outputting the output vector based on an index input.  The distance between the input vector and the output vector is calculated by the distortion computation circuit.  An index output generating means is used to generate an index for a processing period based on the calculated distance value from the encoding section.  Finally, a quantized index output circuit will generate an index of a quantizer from the generated index and will output the index.
