Abstract: A tire force modeling rig and method of obtaining data for use in optimizing cornering performance in a four-wheeled racing vehicle includes first measuring unsprung weight at each wheel. The vehicle is then positioned on the tire force modeling rig. The rig includes a first set of floating scales for recording the weight at each tire on a first side of the racing vehicle, a second set of fixed position scales for recording the weight at each tire on an opposing second side of the racing vehicle, and a mechanism to effect a horizontal force onto the racing vehicle. Scale readings at each wheel are recorded, after which a first horizontal force is applied to the vehicle. With the horizontal force applied, updated scale readings at each wheel are recorded. Collected data can then be used to ascertain optimal car setup.

Abstract: Apparatus for monitoring the progress of operations on mechanical components, such as the fitting of railcar wheels to axles, includes a tachometer monitoring motion of the press ram and generating pulses indicative of increments of forward and rearward movement of a press ram, a chart recorder having a pen whose position indicates the pressure applied to the ram, and a stepper motor driving the chart of the recorder, the stepper motor being supplied with stepping pulses proportional to the net forward motion of the ram as calculated from the outputs of the tachometer. Provision is made for predetermined numbers of forward stepping pulses to be supplied to the motor during rearward movement of the ram so as to separate from the chart the traces generated during successive movements of the ram.

Abstract: This invention relates to an apparatus for measuring and recording the changes in magnitude of a variable. The apparatus includes a recording stylus or pencil and a means for carrying a recording medium such as marking paper. The stylus or the means for carrying is connected to a transducer means which follows the changes in magnitude and provides an output to drive the stylus along the width of the paper in one direction when the magnitude is increasing and in the other direction when the magnitude is decreasing. In addition, either the stylus or the means for carrying the paper are connected to rotating means which rotate in one direction only and which are also driven by the output of the transducer. As the rotating means rotates in one direction only, the stylus will produce a straight line along the width of the paper when the output of the transducer is in one direction, and a straight line at an angle to the first line, when the output of the transducer is in the opposite direction.

Abstract: This invention relates to a liquid level measuring and recording apparatus which includes a recording stylus or pencil and a means for retaining a record such as marking paper. The stylus is connected to a float means which follows the level of the liquid and drives the stylus along the width of the paper in one direction when the level is rising and in the other direction when the level is following. In addition, either the stylus or the paper are connected to rotating means which rotate in one direction only and which are also driven by the up and down movement of the float. As the rotating means rotates in one direction only, the stylus will produce a straight line along the width of the paper when the float is moving in the non-rotating direction, and a straight line at an angle to the first line, when the float is moving in the rotating direction.
