  • Patent number: 9587421
    Abstract: In at least some implementations, a cable control system includes a spool on which a portion of a cable may be taken up and released, an input shaft coupled to the spool, and a motor coupled to the input shaft to drive the input shaft and spool in a first direction to take up cable on the spool and in a second direction to release cable from the spool. The control system also has two clutches that allow rotation of the spool without corresponding rotation of the motor. Each clutch may have a first member coupled to the input shaft and a second member coupled to the spool and relative rotation between the first and second members of the clutch allows rotation of the spool relative to the motor or input shaft.

  • Patent number: 7032648
    Abstract: An investment mould process for forming a cast member is described. The process comprises forming a precursor casting (12) from a master mould (10). The master mould (10) has an internal surface (16) defining a space (14) in which the precursor casting (12) can be formed. The surface (16) defines a location indentation (20) to provide a corresponding location projection (3) on the precursor casting (12). A holding member (22) can be inserted into the location projection (3) to hold an internal member (17A, 17B).

  • Patent number: 6571640
    Abstract: An apparatus and a method for measuring the flexural characteristic of a golf club shaft. The apparatus includes a table having a clamping structure for clamping the golf club shaft thereto. A data collection system having a computer coupled to an image recording device measures the amount of deflection of the golf club shaft before and after a bending moment is applied to the golf club shaft. The stiffness of the golf club shaft is determined from the amount of deflection.

  • Publication number: 20020140621
    Abstract: An existing monopole is strengthened to accommodate loading associated with additional elements included in over-the-air communications systems by fixing strengthening elements to the exterior surface of the monopole. Monopole strengthening may require base plate strengthening, adding anchor bolts and/or foundation strengthening. This permits an existing monopole to accommodate more elements than were initially envisioned when the monopole was initially erected.

  • Publication number: 20020140623
    Abstract: An existing monopole is strengthened to accommodate loading associated with additional elements included in over-the-air communications systems by placing expanding foam and aggregate, light weight aggregate concrete, normal weight aggregate concrete or other types of fill material into the hollow bore in the interior of the monopole. Monopole strengthening may equire base plate strengthening, adding anchor bolts and/or foundation strenghtening. This permits an existing monopole to accommodate more elements than were initially envisioned when the monopole was initially erected.

  • Patent number: 6405595
    Abstract: An apparatus for determining the torsional stiffness of a shaft comprises a rigid frame having a collet for securing one end of the shaft to be measured the rigid frame. A second collet secures the opposite end of the shaft to an inertial weight, which is supported for rotation by a separate bearing so that the inertial weight introduces no axial load in the shaft being measured. The inertial weight has mounted to it a biaxial accelerometer, optical gate or other electronic means for measuring the torsional frequency of the shaft/weight combination. When the inertial weight is displaced from the initial static position and released, the inertial weight oscillates about its center of mass under the urging of the torsional stiffness of the shaft. A computer is programmed with the mass moment of inertia of the inertial weight and therefore is able to solve the differential equation of motion for the torsional spring constant of the shaft based on the frequency of oscillation.

  • Patent number: 5752414
    Abstract: A cable operated interlock system between the gear selector lever (12) of an automatic transmission and the brake pedal (42) restrains the gear selector lever (12) in the Park position until the brake pedal (42) is first depressed. The interlock system includes a shifter cable (68) having one end (70) connected to an L-shaped pedal actuator (62) and another end (72) connected to an inhibitor pin (74) adjacent the gear selector lever (12). A compressible tip (82) is telescopically received over the end of the pedal actuator (62), with a spring (84) trapped therebetween for yielding when the brake pedal (42) returns to its rest position in the event the gear selector lever (12) resides in one of its drive positions. The interlock system may also include an ignition cable (90) extending between an ignition switch (52) of the automobile and the pedal actuator (62).

  • Patent number: 5605074
    Abstract: A motion-transmitting remote-control assembly (10) of the type for transmitting motion along a curved path by a flexible motion-transmitting core element (12) with a conduit (14) slidably supporting the core element (12). A terminal (30) has a bore (32) extending therethrough and defines oppositely facing first (32a) and second (32b) openings with the second opening (32b) disposed for connecting the core element (12) to a control member (24). An adjustment interconnects the terminal (30) and the core element (12) for adjusting the position of the terminal (30) axially along the core element (12) and includes a lock button (36) movable between an unlocked position extending from the assembly and a locked position within the assembly for locking the axial position of the terminal (30) relative to the core element (12).

  • Patent number: 5569113
    Abstract: A transmission with a continuously variable adjustable ratio comprising a first disk fixedly coupled to a first shaft, and a second disk coupled for a rotation about the axis of the first disk. A second shaft is supported for rotation about an axis essentially parallel to the face of the first disk wherein said axis is supported in a tilted position relative to the planar face of the first disk such that the distance between said axis and the first disk planar face increases from said disk center to said disk edge. An idler is coupled for rotation about and axial movement along each second shaft and is in frictional contact with the first disk face. A pinion is fixedly coupled to each second shaft and interconnects with the face of the second disk. Thus, idler axial movement along the second shaft varies both the relative rotational speeds between the first and second disks and the frictional contact pressure between the idler and the first disk face.

  • Patent number: 4744758
    Abstract: An extracoronal attachment for a removable partial denture utilizes a joint comprising a fixed ball within a movable resilient tube to connect the prosthesis to the abutment teeth. The attachment is accurately constructed by a kit and applied by a method which insures that tensile and shear stresses otherwise applied to such attachments during functional loading are significantly reduced so that the male retainer may be permanently secured to the abutment teeth by means of an adhesive bond.
