Abstract: A combination system may include a carburetor in fluid communication with an engine intake tract and a fuel injector in fluid communication with the engine intake tract.

Abstract: A fuel tube system having a tube, a fastening portion, a threaded portion, and a tool connecting surface is presented. The fastening portion is connected to and extends outwardly from the tube. The fastening portion of the fuel tube has an outer diameter larger than the outer diameter of the tube of the fuel tube. The threaded portion is disposed on the outer diameter of the fastening portion. The tool connecting surface is formed in the end of the fastening portion.

Abstract: A fuel bowl for a carburetor system may include a fuel container and a fuel flow assembly that is removeably couplable thereto. The fuel container may include a base, a pair of sidewalls extending upwardly from the base, a rear wall extending upwardly from the base, a top overlying the pair of sidewalls and the rear wall, and a cavity defined by the pair of sidewalls and the rear wall. The fuel flow assembly may include a base, a pair of sidewalls extending upwardly from the base, a rear wall extending upwardly from the base, and a top overlying the pair of sidewalls and the rear wall.

Abstract: An apparatus for measuring the acceleration of an engine for use in a race car for matching the engine to the car for a particular racetrack and includes an engine test stand having a base and an inertia shaft mounted thereto coupled to a gear box. The test stand includes an engine cart for mounting the engine thereto and positionable for coupling the engine to the gear box and has a plurality of selectively engageable inertia wheels attached thereto. The method includes mounting an engine to the engine cart and positioning the engine cart for alignment with the gear box coupling the engine to the gear box. The engine is then accelerated through a predetermined RPM range so that measurements of elapsed time at preselected RPMs can be determined and a selected load to simulate a racetrack length.

Abstract: An apparatus and method for a control unit which allows for autonomous, manual and tele-operation of mining vehicles. The control unit has a robust system design to withstand the harsh environment of underground mines. The control unit allows a tele-operator, in a remote tele-operator station, to use image and operational data, joysticks and foot pedals to remotely control the mining vehicle. In another aspect, the control unit provides safety features such as supervising its operation for operational errors and providing status, warning and error information to the tele-operator station.

Abstract: A vehicle brake pedal has first and second master cylinders and the first pedal arm removably attached to the vehicle having a brake pedal foot pad movably attached thereto. A second brake pedal arm is operatively coupled to the first master cylinder and coupled to the brake pedal foot pad on one end portion thereof for movement of the second brake pedal arm responsive to movement of the brake pedal pad. A third brake pedal arm operatively coupled to the second master cylinder is coupled to the brake pedal foot pad on another portion thereof. The movement of the third brake pedal arm is responsive to movement of the brake pedal foot pad so that the brake pedal foot pad can be rotated to different angles on the first pedal arm to thereby apply different pressure to the first and second master cylinders by carrying the brake pedal foot pad while applying pressure.

Abstract: A method of attaching an internal combustion engine piston oiler includes the step of removing a crank shaft from an internal combustion engine to expose a plurality of block main bearing surfaces, selecting a drill guide shaped to fit one of the engine block main bearing surfaces, which drill guide has a predetermined drill guide bore therethrough, and positioning the selected drill guide on the engine block main bearing surface. The method includes positioning a drill bit through the bore in the selected drill guide and drilling a predetermined bore through the engine block webbing from one main bearing surface into the rear of the engine cylinder and then tapping the bore drilled into the engine block and installing an oil metering jet into the drilled and tap bore.

Abstract: A communication system, particularly for a mine, has a broad band distribution system. Antennas, which may comprise leaky coax feeders, are connected to this distribution system by interface units. As required, the interface units effect signal level adjustment, frequency translation, and/or modulation technique changes. It is provided for each of the distribution system and the antennas to have separate in- and out- bound broad band spectra, with the antenna typically utilizing different frequency bands from the distribution system. A variety of information, including mobile and fixed radio, LANs, data acquisition systems, video, can communicate over this system.
