    Abstract: A process for treating paint sludge in which previously cured paint sludge powder is used as a diluent and mixed with wet paint sludge. The paint powder/sludge mixture is agitated and heated to cure the paint sludge. Processing can occur either continuously or in batch mode, and can be accomplished using a mixer charged with heated gases, or a heated mixer.

    Abstract: A ship steering system has a multiplicity of selectable steering stations. A continuously rotating helm at each steering station generates digital rudder control signals which cause a predetermined rudder movement for each 360.degree. of helm rotation. Steering stations are selected through a multiplexer controlled at a command steering station. The steering system is operable from the command steering station in a plurality of modes, which includes auto-pilot, helm (full-follow-up), and tiller (non-follow-up). Helm and/or tiller modes of operation are available at steering stations remote from the command steering station. The system provides for an emergency takeover from the helm or autopilot modes by automatically establishing the tiller mode when the tiller stick is moved. When in the autopilot mode an alarm system provides an alert should the course deviate from a selected course tolerance.

    Abstract: A method and apparatus are disclosed for the treatment of paint sludge and for reducing volatile organic compound emissions from a paint spraybooth operation, thereby obtaining a recyclable material for use in new coating products. In such an operation, uncured paint resins mixed with volatile organic compounds are sprayed onto an article to be painted and at least a portion of the overspray is mixed with water to form a waste stream containing water, uncured paint resin, volatile organic compounds and inorganic substances. The method includes the steps of: removing a portion of the water and liquid volatile organic compounds from the waste stream; heating the resultant sludge to volatilize the residual water and liquid volatile organic compounds and to cure the uncured paint resin; collecting the residual solids stream, and removing all of the volatilized organic compounds from the resultant stream, thereby generating a volatile organic compound-free gas effluent. The amount of volatized organic compounds removed is at least about 5% of the volatile organic compounds input to the paint spraybooth operation.The apparatus includes a waste paint stream dewatering device and an enclosed rotary screw heat exchanger maintained in an inert environment; the apparatus also provides a system for adding a scouring aggregate to the sludge before heating and for removing the aggregate after heating. Finally, the apparatus includes a separator for removing entrained solids from the resulting gas stream, and provides a system for processing the gas stream to remove all volatile organic compounds.

    Abstract: A low velocity oven seal for use with an elongated oven complex of the type in which articles to be processed are moved longitudinally through the oven. The seal includes an air seal compartment adapted to be aligned with the entry end of the oven complex to form a prefix to the oven complex. In one form of the invention, a blower assembly is mounted on the roof of the air seal compartment adjacent the exit end of the comparment and functions to withdrawn air from the upper region of the air seal compartment adjacent the exit end thereof for delivery to a pair of plenum chambers disposed at either side of the air seal compartment. The air delivered to the plenum chamber is introduced into the lower region of the air seal compartment generally below the path of the articles being processed within the oven complex and this air in turn moves upwardly and toward the exit of the air seal compartment where it is received by the inlet to the blower assembly to complete the air cycle. In another embodiment of the invention, the air is withdrawn from the upper region of the exit end of the air seal chamber by ducting which communicates with the existing exhaust ducting of the convection heating compartment of the oven and the air reintroduced into the air seal through the plenum chambers is supplied to the plenum chambers through ducting connecting with the existing air supply system of the convection heating compartment.

    Abstract: The present invention is directed to a powder paint delivery method and apparatus employing a pressurized reservoir pump that supplies a controlled stream of densely fluidized or dense phase powder paint to the applicator though a powder delivery conduit. The powder flow rate is a function of the pressure in the reservoir and the flow resistance from the reservoir to the applicator, and is therefore very stable over time, and simple to control. The powder flow can be controlled by holding the resistance of the powder flow path constant and varying the pressure in the reservoir, or by holding the reservoir pressure constant and varying the resistance of the powder flow path.

    Abstract: An apparatus for use in measuring fluid flow across a boundary is disclosed including a conduit, supply means for control fluid and two fluid flow sensors. The conduit is positioned to extend across the boundary so that its open ends are located on opposite sides of the boundary. The supply means introduces control fluid at an intermediate point so that control fluid flows through the conduit in opposite directions and discharges through both open ends. The fluid flow sensors are mounted so that each may sense variations in control fluid flow exiting at the ends of the conduit. These sensors generate output signals responsive to fluid flow across the boundary.
