An apparatus for automatically and continuously projecting an elapsed time in which a vehicle traveling over a racecourse will complete the course, wherein a difference between the projected elapsed time and a predicted time is continuously displayed to a driver of the vehicle, so that the driver can adjust the speed of the vehicle as needed during a race to approximate the predicted time. A plurality of magnets are mounted on a drive shaft of the vehicle in a circumferentially spaced relationship. A pickup coil is mounted adjacent to the magnets to detect movement of the magnets past the coil for measuring the distance traveled by the vehicle. A computer is electrically connected to the pickup coil and collects data from the coil for continuously calculating a difference between the projected elapsed time and the predicted time during a race. A motion switch is electrically connected to the computer and detects forward movement of the vehicle at the start of a race for automatically actuating the computer. A light gage is electrically connected to the computer and includes a set of red lights and a set of green lights which, when illuminated, indicate that the projected elapsed time is faster or slower, respectively, than the predicted time in 0.01 second increments. When one or more of the red or green lights are illuminated, the driver can decrease or increase the speed of the vehicle, respectively, so that the elapsed time approximates the predicted time at the end of a race.

Drag race analyzer

The invention provides an electric-arc furnace electrode assembly having electrode sections of improved structural integrity. A pair of carbonaceous electrode sections are held securely in end-to-end relationship by a pin threaded into a pair of sockets found in the respective ends of the electrode sections. Harmful stress concentrations which occur near the base of the socket are reduced by providing a novel base portion. This is achieved by incorporating a generous radius of curvature intermediate the lower-most socket thread and the base of the socket. All of the socket threads are engaged and a threaded portion of the pin extends beyond the lowermost socket thread without engaging the base of the socket.
