摘要： The apparatus and system utilize sprays of steam to clean the exterior or laminated objects, preliminary to electrostatic powder coating, as well as to effect volatilization of liquid contaminates trapped between lamina thereof. Off-gassing that would otherwise occur when the objects are heated to effect fusion of the powder deposit is thereby avoided. The apparatus includes a conveyor for transporting a workpiece along a horizontal travel path through a chamber, above and below which path a spray compartment and collecting compartment are defined, respectively.

摘要： Electrostatic apparatus and method for coating interior surfaces of objects. The apparatus employs a fluidized bed unit in which the fluidization chamber is relatively shallow, and is circumscribed by a marginal portion that conforms closely to the dimensions and configurations of the cavity of the object. The apparatus employs a non-vacuumized powder recovery and recirculation system, and provides a peripheral slot in the marginal portion of the housing for entry of undeposited powder. Coating inside corners of objects is effectively achieved using the method of the invention, and heavy, uniform builds of the particulate material are produced efficiently and at high rates.

摘要： Concrete strengthening members, particularly prestressing tendons such as strands of steel wire, are provided with a strongly adherent plastic coating which may be substantially impermeable for improved corrosion resistance, and/or which may have embedded therein abrasive or grit-form particles to provide improved bond with the concrete, and particularly to provide controllable bond transfer in prestressing tendons of the pre-tensioned type. The plastic coating preferably is applied electrostatically in powder form, and fusion bonded by heat. The abrasive can be applied by spraying during a viscous state of the heated resin, and can be varied as to size and spacing density so as to control the surface condition and the bonding effect. Fusion and curing heat may come from preheating of the member before application of the resin powder, which preferably is a heat curable, thermosetting epoxy. Coating thickness and grit application are readily variable to meet particular requirements. Particularly advantageous results are achievable for high strength steel strands for prestressing concrete by pretensioning, facilitating their use where previously considered impractical or impossible.

摘要： The apparatus, system and method utilize sequential sprays of wet, low-temperature steam, and dry, high-temperature steam to clean the exterior of laminated objects as well as to effect volatilization of liquid contaminates trapped between lamina thereof. Water is injected into the conduit through which the low-temperature steam is delivered, so as to produce a desirable concentration of droplets therein. A conveyor moves the laminated objects along a horizontal path through zones in which they are sprayed by the low temperature and high temperature steam, and then through a zone in which they are electrostatically coated with powder.

摘要： A method and apparatus are disclosed by which electrical conductor cable can be produced utilizing electrostatic coating means, which method and apparatus are highly convenient, uncomplicated and economical to carry out. An outstanding and unique feature of the cable produced in accordance herewith resides in the presence of a web portion of reduced cross-section connecting the individual conductors, by which manual severence of one from another is facilitated. Most desirably, the apparatus and method provide means for producing individual insulating coatings on each of the conductors, which means ideally utilizes an electrostatic cloud coating technique.

摘要： Apparatus and method for coating interior surfaces of objects employs an electrostatic fluidized bed unit in which the fluidization chamber is relatively shallow, and is circumscribed by a marginal portion that conforms closely to the dimensions and configuration of the cavity of the object. The apparatus employs, as a feature of its recovery and recirculation system, a fluidized bed for agitating and facilitating feeding of the particulate material, thus making the system especially well suited for depositing coatings of abrasive materials, such as vitreous frit.
