Abstract: An improved inflator for use in automated wheel/tire assembly lines is disclosed herein. The improved inflator incorporates temperature sensors to sense both the temperature of the compressed air used to inflate the tire and the ambient air temperature in response to which control means will adjust a base reference inflation pressure to compensate for these variables. A pressure sensor is also provided which serves to provide feed back information as to the actual pressure to which the tire is inflated.
Abstract: A system for accurately mixing two or more liquids and for dispensing the mixture. The system is generally adapted for use in paint spraying operations. The flow of one of the components is accurately measured by means of a flow meter and the measured value provides a signal to control a valve which, in turn, controls the flow of the other liquid. Periodically the volume of the first mentioned liquid is measured for a given time period so as to make necessary adjustments in the flow meter-valve interconnection. An improved arrangement is provided for purging a mixing manifold immediately prior to the completion of the dispensing cycle so that none of the mixture will be wasted. The control arrangement includes improved air operated two and three-way valves.
