Abstract: The fire damper of this invention is to protect sensitive areas and equipment from fires which originate in the process of a plant. The invention, for example, may have utility in the protection of bag house filters and the like. It will, however, by way of example only, be largely described herein as applied to an electrostatic air cleaner located on a process stack. In recent years such electronic air cleaners, often in the form of a two-stage electrostatic precipitator, have become quite popular. Such apparatus, however, is quite sensitive to high temperatures such as are occasioned by fires and may readily be destroyed when exposed to them. In this invention a temperature rise is sensed by means of electrical detectors and relayed to the control box of the fire damper.

Abstract: An integrated system for measuring and correcting rubber tires for forces generated by dynamic non-uniformities and for measuring and marking both sides of the tire for lack of symmetry. The force measurements are fed to a computer and the forces indicative of dynamic non-uniformities correlated to given angular positions on the tire by means of a pair of transmissions which act as a shaft encoder, the transmissions incorporating computer controlled timing discs which act through an hydraulic controller to control the honing mechanism which cuts the outside periphery of the tires at the proper locations and in the proper amounts to reduce the non-uniformities to an acceptable low level. Computer control means are also provided to revolve the tires to the proper positions for the marking of their side walls to inidcate points of maximum unbalance so that corrective measures may be thereafter taken to correct the tires for lack of symmetry.

Abstract: A power grid for a fluidized bed for electrostatically depositing a powdered plastic coating material from the bed onto an elongated metal substrate moving in a path of travel above the upper surface of the bed on a substantially horizontal pass line. The power grid includes two co-planar wire mesh elements positioned beneath the surface of the bed, the elements having opposed edges in parallel spaced relationship and defining a gap therebetween beneath the pass line. The edges are upturned to form a plurality of electrode segments, the tips of the electrode segments being substantially coincident with the upper surface of the bed when energized. In operation the electrode segments form a row of localized corona discharges to either side of the passing substrate to effect electrostatic deposition of a thin uniform film coating of the powdered material thereon.

Abstract: Apparatus for transferring articles (such as two-piece cans) between work stations, at succeeding ones of which a dimension (such as a diameter) of the articles is reduced. The articles pass along a channel, and at each station means are provided to stop the articles in position to be operated upon. After the completion of an operation which reduces the dimension of the article, the article may pass the stop means, and be transported to the next station, where other stop means are provided to position the article for the next operation. The articles are conveyed along the channel by aerodynamic or other means. Each of the stop means is shaped to fit the article which is stopped by it, and vacuum means are associated with the stop means to insure accurate positioning of the articles at each station for the operation to be performed on them at that station.
