  • Patent number: 5353358
    Abstract: In an article handling system that functions to make article discrimination-identification determinations, the possible article orientations A, B, C . . . are stored and compared to establish maximum pixel difference numbers and identification of longitudinal window position along the article where such maximum difference occurs. Each of the possible orientations is compared with all other possible orientations so that a small number of windows is identified as part of a setting procedure. When operating, the work articles are scanned and only the data at window locations are used to make article orientation identifications to reduce time and memory requirements for data processing.

  • Patent number: 5347791
    Abstract: The horizontal wrapping machine of the type wherein a succession of articles are fed into a traveling tube of web material which is sealed longitudinally and severed and sealed between the articles to produce individual hermetically sealed packages. A variable speed motor drives a conveyor which may be provided with article feeding flights and a switch, actuated once each revolution of a timing shaft, provides a pulse corresponding to each flight on the article feeding conveyor. In addition an encoder driven by the variable speed drive motor shaft provides a digital velocity signal used as a reference signal for servo motors that may be coupled, in combination or individually, to drive web feed rolls, longitudinal sealing wheels and one or more sealing and severing heads. A delivery conveyor transporting individual packages may, through a suitable drive train, be driven by the variable speed drive motor.

  • Patent number: 5347895
    Abstract: A brake lathe for truing brake rotors includes a tool holder driven by a direct current motor to move a cutting tool radially with respect to the rotor axis in direct proportion to the number of turns of the drive shaft of the direct current motor. A tool feed power control circuit maintains the direct current motor at constant speed regardless of radial forces acting upon the cutting tool and includes a converter/filter circuit, a regulator circuit, a sensing circuit, and a speed control circuit. A speed selection control includes a rheostat for providing a reference voltage corresponding to a select speed. The sensing circuit compares a voltage drop across the direct current motor to the reference voltage and produces an error voltage. The speed control circuit provides a direct current power voltage to the direct current motor in accordance with the error voltage output of the sensing circuit to maintain operation of the motor at constant speed.

  • Patent number: 5311977
    Abstract: A high resolution article handling system serves as an article discriminator or identifier by creating an object silhouette. The objects are singulated on a conveyor and scanned by a linear array of CCD units (2048 pixels per inch) at a scan rate of 10 MHz. Pixel transitions corresponding to object edge points are converted to a single count value from a counter which is synchronized with the scanner. A microprocessor with a first in, first out buffer memory needs only a capacity to handle the count value rather than all data from the pixels. Article orientation is corrected in response to signal generated by determining the count value difference between a reference value and a work article value at only the scan slice windows at equally spaced positions along the article length where differences have been predetermined to be a maximum.

  • Patent number: 5299643
    Abstract: A radially locked subsea housing includes a low pressure housing having upper and lower radial lock regions, each of which regions includes a radial interference surface that is between vertical to only slightly tapered in orientation. A high pressure housing also has upper and lower radial lock regions, each of which regions includes a radial interference surface that is slightly greater in radial diameter than the corresponding interference surface of the low pressure housing. The interference surfaces of the upper and lower radial lock regions form upper and lower interference fits, respectively, between the high pressure and low pressure housings when the housings are assembled subsea.

  • Patent number: 5259451
    Abstract: A down hole well tool for use in operating another well tool against the resistance of incompressible well bore fluid. The down hole tool includes a pressure chamber that communicates through an adjustable pressure relief valve with the well bore fluids beneath the tool, so that when the pressure of said fluids exceeds the relief valve setting the valve opens and allows said fluids to pass into the chamber, thereby lowering the fluid pressure beneath the tool and facilitating its downward movement to actuate the other well tool.
