Abstract: Methods and apparatus are provided for applying a colorant material to the surface of a plastic insulation material which has been applied to an elongated material such as a metallic conductor (22) or an optical fiber which is being moved at any of a wide range of speeds along a path of travel. The colorant material is applied by nozzles which are staggered along the path of travel and which direct the colorant into engagement with the plastic insulation material at different radial directions. A first plurality of nozzles (46--46) each cause the colorant to be in a spray pattern (45) which is in the area of a plane. Advantageously, those nozzles cooperate to stabilize the conductor and prevent undulations thereof as the conductor is moved along its path of travel. A second plurality of nozzles (50--50) cause the colorant to be in a solid conical pattern (53).

Abstract: Can barrels of uniform diameter produced from a can barrel forming device by forming a square-shaped blank into a tubular shape with opposite edges joined linearly, are conveyed successively coaxially in spaced relation at a first speed with the joined areas of the can barrels directed upwardly. Then the can barrels are conveyed at a second speed slower than the first speed such that the open edges of the can barrels are coaxially spaced closely with small gaps left therebetween. Paint is continuously applied to the inner and outer surfaces of the joined areas while the can barrels are being conveyed at the second speed with the open edges of the can barrels being closely spaced by the small gaps.

Abstract: A method for fabricating concrete structural elements is shown. According to the method, a structural element, such as a sheet of insulating material reinforced with concrete, is vertically oriented and coated with fresh concrete sprayed by a shotcrete gun. This coating is then smoothed and shaped as required by the given application. The method does not require the use of moulds to cast the structural element, whose surface is therefore visible at all times during the course of manufacture. This allows for the repair of imperfections before the concrete has hardened.

Abstract: A generally rectangularly shaped powder coating booth of a powder spraying apparatus is fomed of two main sections, each of which is constituted of wall and roof elements which are swingably interconnected to one another. The walls and roof of each half of the booth may be straightened out to form a flat, continuous and rectangularly shaped surface from which residues of powder may be removed easily and rapidly. Thus when the two halves of the booth are flattened out the booth is transformed into two parallel and spaced surfaces which can be cleaned by being vacuumed by a respective suction nozzle that is disposed to travel over and vacuum the surfaces automatically.

Abstract: A nozzle and a method for applying adhesive to join two surfaces. The nozzle has a body member and a conical tip extending from an outlet face of the body member. A first pair of gas passageways is disposed on a side of the conical tip opposite a second pair of gas passageways. Each of the four gas passageways has a dispensing orifice at the outlet face of the nozzle body. The pairs of passageways are inwardly directed to project streams of gas, preferably air, parallel opposed sides of the conical tip. Thus, the streams of air converge at a distance from the outlet face beyond the apex of the conical tip. These streams of air cradle a stream of material issuing from the apex of the conical tip and cause an oscillatory zig-zag deposition of material. The deposition on a first surface has a resonant frequency and has smooth, controlled radius turns at its edges. A second surface is then brought into contact with the first surface while the adhesive is still in a fluid state.

Abstract: At least one complete surface of at least one metallic part of a can is given a uniform coating of corrosion-preventing lacquer and this part is subsequently worked such that the metal of the part is exposed at regions at least immediately adjacent the coated surface. Dots of lacquer are sprayed by the ink-jet method substantially only on the exposed regions of the part after working thereof and so that the dots together form a continuous layer covering the exposed regions. According to the viscosity of the lacquer the surface coating can be achieved by partially overlapping adjacent dots of the applied lacquer or without overlapping by the running together of the adjacent dots of the liquid, with no excess material having to be applied to and subsequently removed from the regions to be coated.

Whenever a sensor senses a notch in a flange of the moving part, application of material to the moving part is stopped for a predetermined distance prior to the start of the notch to a predetermined distance beyond the notch. Application of material to the moving part is finally stopped a predetermined distance prior to its trailing edge. Two separate sensors are used to control each of three spray guns for applying the material in the selected areas.

Abstract: In the case of sequentially coating workpieces, such as motor vehicle bodies, with a program controlled painter-robot, it has hitherto been difficult or impossible to finish painting a partly coated workpiece in the event of an unscheduled breakdown. This was because the robot and the workpiece would inertially overrun their synchronized relative positions after the breakdown, thus making it difficult to resynchronize the two. According to the subject invention, based upon the synchronized relative positions of the workpiece and the painter-robot both at the time of the breakdown and after the unit has come to stop, a path of travel is determined over which the robot is returned accurately to the relative position at which the breakdown occurred. The coating operation is then resumed from this position.

Abstract: Methods and apparatus are described for the random coloring of concrete roof tiles during the manufacture of such tiles. This enables the tiles to be installed in random fashion and without following any particular sequence. At the same time a roof is achieved which has an aesthetically pleasing random variation of the tile colors and which is absent the displeasing color patterns which often occur when tiles colored by a simple and frequently repeating pattern are not installed in proper sequence. Newly formed concrete tiles are sequentially advanced by a conveyor beneath a base applicator which sprays a base coat of coloring slurry over essentially the entire top surface of each tile. One or more overspray applicators located downstream from the base applicator then spray additional colors over different portions of the top surfaces of the tiles in intermittent, randomly varying fashion so that the color pattern on each tile is essentially unique and is not repeated on any other tile.
