20090277270 | METHOD FOR INSPECTING JOINED MATERIAL INTERFACES - A method for inspecting joined material interfaces, such as butt fusion pipe joints of plastic pipes, using ultrasonic waveforms to discriminate between acceptable and unacceptable interfaces. The waveforms (amplitude vs time) having been transmitted to a material interface of interest are divided into a number of time zones and the amplitudes of the waveforms within the time zones compared against waveform amplitudes obtained from known acceptable joined material interfaces to determine the quality of the material interface of interest. | 11-12-2009 |
20110146407 | METHOD FOR IDENTIFYING DEFECTIVE HEAT FUSION JOINTS - A method for characterizing a defect of a defective heat fusion joint connecting two pipe segments in which the time of flight of an ultrasonic waveform reflected off an exterior surface of a heat fusion joint fitting connecting the two pipe segments or reflected off an interior wall of one of the pipe segments at a plurality of locations around the circumference of the heat fusion joint fitting is measured to determine the minimum and maximum times of flight, which correspond to the maximum and minimum combined wall thicknesses of the heat fusion joint fitting connecting the pipe segments and the pipe segment wall. If the difference between the minimum and maximum combined wall thicknesses as determined from the measured times of flight is equal to or greater than a predetermined amount, then the heat fusion joint is defective and possibly unacceptable for use, requiring a second set of time-of-flight measurements to characterize the nature of the defect. | 06-23-2011 |
20120043960 | NON-INTRUSIVE DETECTION OF LIVE ELECTRICAL LINES - A method for determining a presence of live 3-phase electrical lines inside a buried pipe or conduit from outside the pipe or conduit and preferably from an above ground location. A sensor suitable for detecting vibratory signals is placed on the ground proximate the location of the buried pipe. The sensor is then used to determine the presence of a current frequency signal and a current harmonic frequency signal, whereby presence of the current frequency signal and/or the current harmonic frequency signal corresponds to a presence of a live 3-phase electrical line within the buried pipe or conduit. Although intended primarily for use in connection with buried pipes, the method may also be employed on exposed pipes and conduits. | 02-23-2012 |
20130043887 | COMMUNICATION METHOD FOR MONITORING PIPELINES - A method for underground pipeline monitoring in which a continuous alternating electrical current having a current frequency in a range of about 1 kHZ to about 8 kHz is imparted onto a pipeline, producing an alternating magnetic field at the current frequency along the pipeline. Distributed along the pipeline is a network of RFID tag sensors which absorb an amount of energy from the alternating magnetic field. The impedance of the sensors is modulated, producing a modulated sensor impedance which is detected at a location proximate the location at which the continuous alternating electrical current is imparted onto the pipeline. | 02-21-2013 |

20100153310 | DEVICE AND METHOD FOR ACCEPTING MAIL PIECES - A device and a method for mail piece acceptance; with a mail item feed for mail pieces; with a user interface and with a accounting unit; with a card reader with cover plate into whose slit a postage credit card or an authorization card can be inserted; wherein after the settling the postage fee by the accounting unit a storage in secured storage containers in the storage region ensues; wherein the mail item feed is equipped with an adjustable opening of a feed shaft for depositing and for drawing in a mail piece; wherein the mail piece is an element of a set of mail pieces whose dimensions can be different; and the mail piece acceptance device has a number of devices for scanning the mail piece surface, for automatic position alignment of the mail piece, for transport, for printing a marking on the mail piece and for storage of the mail piece; wherein for storage a deflection of each of the mail pieces to a specific storage container ensues, which storage container is dimensioned corresponding to a size-accurate collection of mail pieces. The variable size of the adjustable opening of the mail item feed is set corresponding to the cost features input by the user. | 06-17-2010 |
20110206482 | FASTY DYNAMIC SCALE AND METHOD FOR CONTROLLING A FAST DYNAMIC SCALE - A fast, dynamic scale has a weighing unit formed by a weighing cell and a transport mechanism with a first motor to drive the transport mechanism. The transport mechanism) is arranged with the motor on the weighing cell, so the weighing cell is loaded with a preliminary load. A first sensor is located at the beginning of the weighing unit. This first sensor emits a first signal to a control unit to start the weighing process for a cargo piece B. A second sensor emits a second signal to the control unit that thereupon generates a communication that a cargo piece Bn following the cargo piece B can be supplied. A weighing unit with a shortened effective length for the weighing is provided. The shortened length allows the interval between successive cargo pieces to be correspondingly shortened. A switchable extraction device is arranged after the weighing unit in the transport direction. The control unit controls the cargo piece transport by means of a third motor of the extraction device and to control the extraction device depending on the length of the cargo piece and on the termination of the weight determination as a result of the weighing, with the extraction device being switched by an actuator. | 08-25-2011 |
20120222094 | METHOD AND ARRANGEMENT FOR ENABLING THE USE OF A CONSUMABLE UNIT - In a method for enabling the use of a consumable unit in a consumption device of a consumption arrangement, a first item of authorization information assigned to the consumable unit is transmitted from the consumption arrangement to a remote data center. The data center implements a first verification of the first item of authorization information and, as a function of this verification, a second item of authorization information assigned to the consumable unit is generated. The second item of authorization information is transmitted to the consumption arrangement, which implements a second verification of the second item of authorization information, dependent on which use of the consumable unit in the consumption device is enabled. The outcome of either the first or second verification is also used for an accounting for use of the consumable unit when, the first verification indicates that the consumable unit was previously unused. | 08-30-2012 |
20120279787 | DYNAMIC SCALE WITH MULTIPLE WEIGHING PANS, AND METHOD TO OPERATE THE DYNAMIC SCALE - A dynamic scale has multiple weighing units, each equipped with a weighing cell and a weighing pan, the weighing pan lying in an upper plane and the weighing cell between a lower plane spaced from the upper plane in the direction of gravity. A transport device has a motor encoder and sensors, with the encoder and sensors being electrically connected with the inputs of a control unit. The multiple weighing units are serially adjacent in a transport path, with simultaneous cascaded arrangement of the weighing cells in the direction of gravity. The control unit simultaneously starts the weighing processes in all weighing cells in a dynamic weighing mode and controls a transport motor depending on signals of the sensors and the encoder and controls the dynamic scale depending on signals from the weighing cells. | 11-08-2012 |
