  • Publication number: 20200382921
    Abstract: Minimally invasive surgical methods employ an offset drive shaft to actuate an end effector. A minimally invasive surgical method includes introducing an end effector to an internal surgical site. The end effector includes an end effector base that is coupled to the instrument shaft via a wrist. An end effector articulation mechanism is operated to reorient the end effector base relative to the instrument shaft. A surgical task is performed by operating a motor to rotate an offset drive shaft relative to the instrument shaft to actuate the end effector.

  • Patent number: 10779896
    Abstract: Mechanisms, assemblies, systems, tools, and methods include an offset drive shaft within an independently rotating member. An example method of transmitting torque through an offset drive shaft routed within a rotatable main shaft includes supporting a main shaft to rotate relative to a base so that the main shaft rotates about a main shaft rotational axis. A drive shaft is supported to rotate relative to the main shaft so that the drive shaft rotates about a drive shaft rotational axis that is offset from the main shaft rotational axis. The drive shaft is engaged with a drive feature having a drive feature rotational axis that is fixed relative to the base as the main shaft rotates. The main shaft is rotated relative to the base. The drive feature is rotated relative to the main shaft so as to rotate the drive shaft relative to the main shaft.

  • Publication number: 20200188746
    Abstract: A golf club head that is capable improving on the inertia properties of a golf club head all while also improving the Center of Gravity (CG) location is disclosed herein. More specifically, the golf club head in accordance with the present invention achieves a relative low Moment of Inertia (MOI) about the Z-axis (MOI-Z) as well as a relatively low MOI about the Shaft-axis (MOI-SA), all combined with a high MOI about the X and Y-axis (MOI-X and MOI-Y) and maintaining a consistently and relatively low CG location measured along a direction tangent to the hosel axis along the X-Y plane (CG-B).

  • Patent number: 10292767
    Abstract: Surgical tools having a two degree-of-freedom wrist, wrist articulation by linked tension members, mechanisms for transmitting torque through an angle, and minimally invasive surgical tools incorporating these features are disclosed. An elongate intermediate wrist member is pivotally coupled with a distal end of an instrument shaft so as to rotate about a first axis transverse to the shaft, and an end effector body is pivotally coupled with the intermediate member so as to rotate about a second axis that is transverse to the first axis. Linked tension members interact with attachment features to articulate the wrist. A torque-transmitting mechanism includes a coupling member, coupling pins, a drive shaft, and a driven shaft. The drive shaft is coupled with the driven shaft so as to control the relative orientations of the drive shaft, the coupling member, and the driven shaft.

  • Patent number: 5565622
    Abstract: A simplified method for solid phase extraction of components of interest from a sample employing a syringe in which the inner surface of the cannula or needle is at least partially coated with a stationary phase such that aspirating the sample into the needle results in adsorption of the components of interest into the stationary phase. Aspiration of a solvent may be employed for removing the components of interest from the stationary phase for direct injection into a chromatographic instrument, or the components of interest may be removed by thermal desorption, wherein the needle is placed in the injection port of the chromatographic instrument and heated.

  • Patent number: 5470487
    Abstract: A cap for sealing pressure vessels is disclosed. The present invention permits a nominal closure to be formed by hand tightening and a substantially higher force to be applied to a cap by a separate clamp mechanism, thereby forming a pressure seal. In certain preferred embodiments, means for providing a process flow through a hole in the seal and filtering means are also provided as part of the cap assembly. A preferred application of the cap of the present invention is for the sealing of sample vessels used for supercritical fluid extraction of compounds from a solid matrix for subsequent chemical analysis. Methods of supercritical fluid extraction are also disclosed. The present invention thus provides methods and apparatus whereby the placement of a sample into a pressurized system may be automated and monitored to ensure adequate seals have been created and maintained within such pressurized systems.

  • Patent number: 4507137
    Abstract: A conveyor apparatus for receiving and transporting cylindrical stock or articles past work stations includes a plurality of rollers disposed along spaced-apart parallel axes. The rollers are driven through one-way or overrunning clutches and rotate cylindrical stock disposed between adjacent pairs of rollers. At a work station, a moving member such as a belt engages the stock and rotates it at a speed higher than the speed imparted to it by the rollers. The overrunning clutches release the conveyor rollers and rotate with the stock at a correspondingly higher speed. The constant, non-slipping contact between the rollers and stock minimizes such difficulties as scoring of the stock and significantly improves product quality and appearance.
