  • Patent number: 10436145
    Abstract: A marine engine operates according to first and second sets of mapped parameter values to achieve a first fuel-air equivalence ratio and maintains a stable output torque while transitioning to operating according to third and fourth sets of mapped parameter values to achieve a different fuel-air equivalence ratio. The first and third sets of mapped parameter values correspond to a first combustion parameter. The second and fourth sets correspond to a second combustion parameter. The transition includes: (a) transitioning from operation according to a current value of the first combustion parameter to operation according to a target value thereof; (b) transitioning from operation according to a current value of the second combustion parameter to operation according to a target value thereof; and (c) timing commencement or completion of step (b) and setting a rate of step (b) to counteract torque discontinuity that would otherwise result when performing step (a) alone.

  • Patent number: 6007332
    Abstract: A method and system for determining the color characteristic of a tooth, particularly in a mouth in which restorative dentistry is contemplated, employs the photographic imaging of the tooth of the patient, and the photographing of visually selected color standards, to achieve the final selection of the closest color match. The resulting photographic images, which may be on a single photograph, are subjected to calorimetric or spectrophotometric analysis to achieve the final selection of the closest match. The system avoids the need to rely upon the visual color acuity of the practitioner in order to achieve a close color match for a prosthetic device. Additionally, the method and system of the invention avoid the problems associated with color shifts associated with photography, when such is used alone as the indicator of tooth color.

  • Patent number: 5605017
    Abstract: A utility line support structure for use as a tangent crossarm or deadend including a hollow fiber reinforced beam with a bushing inserted into a transverse hole in the beam. Bushing includes a hollow inner member for receiving a bolt and a pair of integral washers arranged on opposite ends of inner member and against an outer surface of the beam. The hollow inner member and the integral washers cooperate to support axial loads applied by the bolt. End caps extend over opposite ends of the beam to seal the beam so as to prevent moisture from entering the beam. Also, a method for adapting a non-standard-sized utility line support beam to be compatible with standard-sized tooling.

  • Patent number: 5242305
    Abstract: The amount of mercury released from amalgam restorations in the teeth of living beings is significantly reduced without changing the composition of the silver-tin-copper alloy or changing the mercury-alloy ratio. This is achieved by introducing a mercury-absorbing metal component which acts only during the final setting stage of the amalgam. In a process embodiment, this is achieved by introducing a mercury-absorbing metal component which is applied to the prepared tooth cavity walls where it absorbs excess mercury from the setting amalgam. In a composition embodiment, the composition of the amalgam restoration consists of three components: a finely divided silver-tin-copper alloy; mercury; and a mercury-absorbing metal powder containing at least 50% by weight of palladium and the remainder of the group consisting of gold, copper, platinum, indium, zinc, and silver, some of which may be present as a coating on the palladium base powder.

  • Patent number: 5080588
    Abstract: Apparatus and method for finishing a surface, such as the surface of a tooth, for improving the strength of an adhesive bond. A plurality of cuts are made into the surface at an angle which is less than 90.degree.. Undercuts are thus formed which enhance the micromechanical engagement between the surface and the solidified adhesive material. The undercuts are dimensioned in response to the viscosity characteristic of the fluid adhesive material so as to promote flow of the fluid adhesive material into the undercuts by capillary action. The undercuts are formed by application of a rotary tool to the surface, the tool having a plurality of spaced-apart edges thereon, which are applied to the surface so that each such cutting edge makes a respective undercut.
