  • Publication number: 20250100332
    Abstract: A track attachment includes a track body forming a convex surface for facing a driving terrain and a concave surface for facing a wheel or tire, with at least one blade extending from the convex surface for increasing lateral traction of the wheel or tire. The at least one blade may be defined as an elongated shape extending in the direction of rotation of the wheel or tire to generate and increase in lateral traction. The track body and at least two blades may define a channel at the convex surface to generate a floating effect on soft and loose terrain. The track attachment may be provided with supporting ribs and openings for facilitating attachment to the wheel or tire. A traction system includes a plurality of track attachments secured to a wheel or tire.

  • Publication number: 20210262582
    Abstract: A pneumatically controlled flow booster includes a booster valve plug position sensor that enables control of the flow booster in a feedback loop, for example by a pneumatic valve positioner, thereby providing accurate, high speed, high flow control of both small and large actuator adjustments. Embodiments can accurately control a surge suppression valve over extended valve adjustment ranges and can fully open a surge suppression valve during a trip. The flow booster valve can include a spool and sleeve valve and/or a poppet valve. Embodiments provide bimodal flow boosting, whereby the output flow is less dependent on the valve plug position in a first position range, and more strongly dependent on the valve plug position in a second range.

  • Patent number: 10107415
    Abstract: A valve positioner monitors a valve stem position by remotely sensing a magnet attached to a coupler shaft that does not penetrate a sealed enclosure surrounding the positioner. A torsion spring, which can be helical or spiral, concentrically surrounds the shaft and is fixed to the shaft and frictionally coupled to a fixed surface by a clutch ring that coaxially surrounds the spring and is vertically pressed against the fixed surface. The torsion spring thereby suppresses backlash, vibration, and chatter by maintaining a torsional force on the shaft. The clutch ring can include a notch or slot cooperative with a key tab rotationally fixed to the coupler shaft so as to limit a range of rotation of the coupler shaft. The positioner is rendered compact by the concentric arrangement of its elements, so that embodiments can be used in place of legacy positioners.

  • Patent number: 8007279
    Abstract: Disclosed within is a dental restorative system including an impression coping with a body portion having a first end, a second end, and an internal chamber having non-frustoconical side walls. The body portion also has a facial aspect and a lingual aspect and the distance between the first end and second end on the facial aspect is greater than the distance between the first end and second end on the lingual aspect. The first end of the impression coping may include an opening and an interproximal, continuous slope. Certain embodiments of the impression coping include means for engaging an abutment or implant, located on the internal chamber. Other embodiments include external flange portions for retention of the coping in impression material. Alternative embodiments of the impression coping are also disclosed.

  • Patent number: 6267559
    Abstract: The present invention utilizes a torque compensation system and a power control feedback system to reduce power consumption in a linear peristaltic pump. The linear peristaltic infusion pump includes an electric motor, which is connected to a cam shaft with multiple cams positioned thereon. Numerous elongate fingers cooperate with the cams to partly occlude an intravenous drip tube at multiple points along the tube's path. A torque compensation system and power feedback control system reduce the overall power consumption of the pump. A torque compensation cam positioned on the cam shaft, in combination with a torque compensation cam follower and a mechanical spring assist the motor while it is working against a rising cam follower. The power feedback control system comprises a controller which optimally adjusts the power supplied to the drive means so as to reduce overall power consumption of the pump.
