  • Device for winding / taking up cables, ribbons, or other coilable structures
    Patent number: 6971605
    Abstract: A cable take-up device has a central spool situated between opposing first and second spool end walls, wherein the first spool end wall is rotatable and bears a cable guide thereon which reciprocates along the length of the spool during such rotation. Cable inserted through a cable guide aperture in the cable guide is thereby wound about and along the length of the spool when the first spool end wall is rotated to cause the cable guide to orbit the spool. The first spool end wall preferably bears a feed aperture therein which feeds cable into the cable guide aperture in a direction oriented generally axially with respect to the spool, with the feed aperture being defined within a feed tube which protrudes from the first spool end wall to define a cranking handle.

  • Method and apparatus for controlling spark ignition in an internal combustion engine
    Patent number: 5038744
    Abstract: A method and apparatus for controlling spark reignition in an internal combustion engine based on the detected luminosity or pressure in the combustion chamber is provided. Only the luminosity or pressure measurement may be used as a basis for this control. This method and apparatus is also capable of providing same cycle control of spark reignition.

  • Method of operating an engine and measuring certain operating parameters
    Patent number: 4940033
    Abstract: An internal combustion engine having a luminosity probe and an arrangement for measuring certain parameters such as IMEP, combustion chamber pressure, heat release and the like by measuring luminosity in the chamber and adjusting the running parameters of the engine to obtain the desired luminosity. Also disclosed is an arrangement for maintaining uniformity from cycle to cycle in a given combustion chamber and uniformity combustion in the combustion chambers of a multi-chamber engine.
