  • Patent number: 9908756
    Abstract: A constant pulling force winch control system includes a sensor that senses a degree of winding of a winch cable around a winch drum, and a control system configured to control a winch motor to achieve a constant pulling force on the winch cable based on the degree of winding sensed by the sensor. The sensor may be a position sensor that measures a position of the winch cable relative to a centerline of the winch drum as the degree of winding. The position sensor may sense an angular position of a tension plate relative to a tensioner shaft to measure the degree of winding. The winch motor may be a hydraulic winch motor or an electric motor, and the control system is configured to control the power applied to the hydraulic winch motor to achieve the constant pulling force based on the degree of winding sensed by the sensor.

  • Patent number: 9463965
    Abstract: A pulling tool is provided with a rotatable drum having a cable wound thereon. A motor is drivingly connected to the rotatable drum and the rotatable drum and motor are disposed within a unique housing structure. The rotatable drum is driven by a planetary gear system that is disposed within the rotatable drum to provide a compact assembly. A belt and pulley system is provided for delivering torque from the motor to the planetary gear system. The rotatable drum is provided with a two-piece stepped construction that allows the planetary gear system to be assembled within the drum and allows for the initial wraps of a cable around the smaller diameter portion of the stepped drum.

  • Publication number: 20110180770
    Abstract: A winch includes a rotatable drum. A cable is wound onto the drum in one rotative direction and off the drum in a second rotative direction. A sealed axial flux permanent magnet drive motor includes a drive shaft selectively rotated by the motor in either direction of rotation. A gear train interconnects the drive shaft and the drum for rotatably driving the drum at a reduced rotative speed relative to the motor shaft. The motor can apply regenerative braking. A spring-applied electric release brake is connected to the drive shaft to apply a braking force to prevent rotation of the drum. A connecting shaft connects the gear train to the rotatable drum. The connecting shaft includes axially spaced splines that reduce the disparity in the gear train and drum centerlines to thereby reduce gyration therebetween. The drum can be made partially from carbon fiber to reduce the weight thereof.

  • Patent number: 6460671
    Abstract: A clutch control for shifting a vehicle drive system as between automatic four-wheel drive, locked four-wheel drive and two-wheel drive. An engagement system for engaging drive and driven components of the drive system may include roller clutch engagement or pawl clutch engagement. The clutch system is provided with a coupling mechanism for coupling the engagement member to ground or to the driven member to thereby achieve automatic four-wheel drive and locked four-wheel drive, respectively. The engagement member is decoupled from both ground and the driven member to achieve two-wheel drive.

  • Publication number: 20020112934
    Abstract: A hub clutch mechanism wherein actuation of the clutch ring movement is provided by an over-center spring. A first spring portion is secured to the clutch ring and a second spring portion is movably secured at the clutch ring center. The second spring portion is offset axially from the first spring portion and biases the clutch ring away from the first spring portion. Stops restrict movement of the first and second spring portions which enables movable positioning of said second spring portion from one side to the other of said first spring portion and thereby urging reverse axial movement of the clutch ring.

  • Patent number: 5917528
    Abstract: A solid ink stick supply system and related method for delivering solid ink sticks to an ink jet print head reservoir is disclosed. The supply system includes a housing with a keyed plate that guides the ink sticks into the proper loading position in a supply channel. A pusher rod in the supply channel transfers an ink stick onto an endless belt for delivery to the print head reservoir. A push device on the endless belt engages and delivers the ink stick to the print head reservoir. A second ink stick is transferred from the supply channel to the endless belt and is retained on the belt by a stop device. A method for efficiently loading ink sticks into the supply system is also provided.

  • Patent number: 5805191
    Abstract: An apparatus and method are described for applying an intermediate transfer surface, in the form of a liquid layer, on a support surface as may be used in a phase change ink printing system. The apparatus includes an applicator assembly for distributing the liquid layer onto the support surface to produce the intermediate transfer surface and an apparatus for metering the liquid layer uniformly on the support surface. The applicator assembly has a contact medium for removing foreign matter from and delivering the liquid onto the support surface. Preferably the contact medium is a liquid impregnated web that is periodically incremented to present a clean web surface in contact with the support surface. The metering apparatus is a hydrodynamic blade that uniformly distributes the liquid intermediate transfer layer over the support surface.

  • Patent number: 5614933
    Abstract: A phase change ink transfer printing apparatus (10) applies a liquid intermediate transfer surface (12) to a heated drum (14, 28). Because the intermediate transfer surface is a thin liquid layer, molten ink drops (122) striking it flatten and spread out (110, 112, 114, 130) prior to cooling and solidifying as an ink image (26, 130) at the drum temperature. After the ink image is deposited, a print medium (21, 132), such as a transparency film, is fed into a nip (22) formed between the heated drum and an elastomeric transfer roller (23). As the drum turns, the print medium is pulled through the nip to transfer the ink image to the print medium. When in the nip, heat from the drum and print medium combine to heat the ink in accordance with a process window (90), making the ink sufficiently soft and tacky to adhere to the print medium but not to the drum. The ink drops comprising the ink image have a desired diameter to height ratio of from about 1.

  • Patent number: 5608430
    Abstract: A print head (216) tilt angle positioner (258) includes a scroll cam (344), a tilt arm (332), a flexure (334), a tilt angle adjuster (336), and a biasing spring (338). The tilt arm and the print head are attached to a shaft (220) that rotates the tilt arm and the print head together between printing, maintenance, and shipping tilt angle positions to control the distance of the print head from the image receiving drum.
