  • Patent number: 10173413
    Abstract: A rotary printing machine includes a printing cylinder, at least one clamping unit mounted on a printing surface of the printing cylinder, and a feeding control mechanism and an unloading control mechanism mounted to a lateral side of the printing cylinder for changing the clamping state of the clamping unit. When the clamping unit is moved to an unloading position, the unloading control mechanism can be operated to control the clamping unit to maintain a closed state, so that a workpiece can be brought by the printing cylinder to a feeding position again. Then, the feeding control mechanism can be operated to control the clamping unit at the feeding position to maintain a clamped state, so that printing can be repeated on the workpiece to form multiple layers of ink and create three-dimensional printed layers showing a specific visual effect.

  • Patent number: 10150198
    Abstract: A method of inspecting a cutting blade having a cutting edge formed of abrasive grains of selected abrasive grain diameters which are bound by a bonding material, includes a cutting step of moving the chuck table and the cutting blade, which is being rotated at a high speed, relatively to each other along a direction perpendicular to an axis of rotation of a spindle, thereby forming a cut groove in the workpiece, and an inspecting step of capturing an image of the cut groove formed in the workpiece by image capturing means, and inspecting the state of the cut groove. The inspecting step examines whether or not the selected abrasive grain diameters are proper on the basis of any of the elements representing the size of an average chip, the number of chips, and the area of chips on both sides of the cut groove per unit length.

  • Patent number: 10145770
    Abstract: A conveyor or drive chain wear monitor includes two sensors spaced apart from one another a predetermined distance which is less than the distance between the two selected measuring points on a chain. Two timers are provided, one of which is a chain speed timer and the other of which is the chain wear timer. The two timers are both controlled by the spaced sensors. The problem of sensor beams being broken by irrelevant beam breaking obstacles located between the successive spaced measuring points is solved by providing an ignore obstacle software routine in the wear monitor computer. The ignore obstacle software routine allows a user to program the monitor to ignore any number of irrelevant obstacles which might occur between two spaced measuring points on a chain.

  • Patent number: 10125600
    Abstract: A system and method of sensing fluid in a wellbore, where fluid along a range of radial locations in the wellbore is diverted along a flow path that runs adjacent a fluid sensor. Diverting the fluid from the range of radial locations provides a representative sample of the fluid flowing in the wellbore. Further, the diverted fluid forms a continuous volumetric flow past the fluid sensor to avoid fluid stagnation adjacent the fluid sensor. Diverting the fluid flow can be accomplished by elongate diverter wings attached at discrete circumferential locations around an outer surface of a fluid sensor and that project at oblique angles to the direction of flow. Elongate members can be used for diverting flow, where the distal ends of the elongate members attach to a downhole tool, and vane members span across selected adjacent members for directing flow to the sensor.

  • Patent number: 10124572
    Abstract: Provided is a method for automatically adjusting the contact pressure between an intaglio cylinder and a wiping roller that further limits the amount of defective prints generated. The method adjusts said contact pressure by changing the position of the wiping roller shaft center with respect to the intaglio cylinder shaft center using a contact pressure adjustment motor. At least the position of the wiping roller shaft center at low speed and the position of the wiping roller shaft center during printing operation for which the contact pressures have been optimized during a previous printing are stored. Before starting the current printing operation, the wiping roller is moved to the stored low speed position. Then when the current printing operation is started, the wiping roller is moved to the stored printing operation position.

  • Patent number: 10067112
    Abstract: An improved sensor fish with robust design and enhanced measurement capabilities. This sensor fish contains sensors for acceleration, rotation, magnetic field intensity, pressure, and temperature. A low-power microcontroller collects data from the sensors and stores up to 5 minutes of data on a non-volatile flash memory. A rechargeable battery supplies power to the sensor fish. A recovery system helps locating sensor fish. The package, when ready for use is nearly neutrally buoyant and thus mimics the behavior of an actual fish.

  • Patent number: 10060251
    Abstract: A method of measuring fluid flow conditions in a wellbore includes generating an acoustic probe signal during fluid flow along the wellbore, measuring the performance attribute of the acoustic probe signal within a target frequency range, and of the fluid medium in at least a part of the wellbore based on the measured performance parameters. The target frequency range of the acoustic probe signal encompasses a bubble resonance frequency range for vapor bubbles in the wellbore, for example having frequencies in excess of 20 kHz. An estimated bubble size value may be calculated based on determining a frequency at which the measured probe signal experiences the retardation or peak attenuation.
