Abstract: A method is provided for collecting measurement parameters related to imbalance forces of a tire/hub assembly of a vehicle during motion of the vehicle. An apparatus is removably attached to the tire/hub assembly of the vehicle via lug nuts of the tire/hub assembly. The apparatus includes a disk, a plurality of cup-shaped objects, and one or more inertial measurement units (IMU's) mounted to the disk. Each of the cup-shaped objects are rigidly fixed at one end to the disk and extend perpendicularly outward from the disk. The plurality of cup-shaped objects are arranged a fixed radial distance from a radial center of the disk in a pattern that matches the lug nuts of the tire/hub assembly. The one or more inertial measurement units (IMU's) are mounted to the disk and configured to measure parameters that are used for calculating the imbalance forces during motion of the vehicle.

Abstract: Method and apparatus for detecting a limit of a usable portion of a batch of fluent material flowing in a conduit from a container wherein usable and unusable material lie in layers. The embodiment disclosed includes two containers each having a conduit leading from the container to a switching valve. Each conduit is provided with a sensor for sensing the conductivity of fluent material flowing in the conduit. Signals from the sensors are sent to a computer which has in memory a range of values for the conductives of usable material. When the signal from a sensor goes outside that range the computer generates a signal to the switching valve to cause the switching valve to discontinue flow from the one container and allow flow from the other container which contains a fresh batch of fluent material. A conduit leads from the switching valve to a coating hopper for coating a thin layer of photographic emulsion on a continuous web. The unusable material may be froth on top of the usable material or it may be air.
