This allows a simple and speedy turn of the plurality of substrates. Further, even the apparatus for processing the substrates in a vertical attitude can transfer the substrates into and out of the apparatus in the horizontal attitude by using the common carrier.

Abstract: The apparatus and method for processing steel strand wire cable and the like for use in prestressed concrete is disclosed in which the outer surface of the cable produced has a substantial pure rust or hydrated oxide coating thereon enabling the cable to be utilized immediately in concrete configurations to thereby produce substantially higher flexural strengths in prestressed concrete than heretofore in the prior art. The apparatus and method specifically encompasses the use of ultransonic cleaning equipment which causes cavitation cleaning effects in the liquid medium through which the cable passes during its cleaning process. In effect, the ultrasonic cleaning "catalyzes" the chemical redox reactions by removing all surface inhibitors and reducing reactant diffusion barriers thus accelerating surface wetting of the strand cable with H.sub.2 O and O.sub.2, such that the rusting chemical reactions can occur spontaneously. The dominant bond developed between the steel and concrete is chemical.

Abstract: An apparatus and method are herein described for cleaning and waxing automobiles in commercial "car wash" operations without any need for mechanical buffing or polishing as, for example, with brushes. The surface of the car is first covered with a water soluble, agitated liquid cleaner which has been at least partially foamed. Then, the surface of the car is blasted with water soluble beads under sufficient pressure to apply a frictional cleaning motion to the liquid cleaner, but with insufficient pressure to damage the car surface by excessive abrasion. After the blasting step, the liquid cleaner and water soluble beads are rinsed by the application of a high pressure water spray thereto. If it is desired to wax the car surfaces, microcrystalline beads of dry, water soluble, carnauba wax are blasted against the car surfaces with sufficient pressure to cause frictional buffing and polishing of the surfaces, but insufficient pressure to damage the surfaces with abrasion.

Abstract: In an electrostatic high speed line printer, a pair of lightly wetted cylindrical rollers are sequentially arranged upstream of the print station to engage the paper surface to be printed. The roller surfaces are wetted with a very thin film of non-staining viscous film such as isopar, and driven at roughly the same speed as the paper causing the paper surface to be very slightly wetted, thereby tending to attract debris particles from the surface of the paper to the roller and also tending to cause other debris particles to be adhered to the paper surface at least until after they have passed through the print head. A dancer roller is positioned on the opposite side of the paper from the wet rollers, between the wetted rollers, to provide approximately 30.degree. of wrap across each wetted roller.

Abstract: This invention discloses the structure of, and the method and apparatus for making, improved metal-matrix composites. Each of the composites comprises a strain-hardenable metal matrix, and a plurality of high-strength, high-modulus, elongated reinforcing members arranged in spatial relationship therein. Each of the members is effectively bonded to the surrounding matrix at selected, discrete surface regions along its length so as to locally strain the matrix around the discretely bonded regions upon the composite being suitably stressed. When thus locally strained, the matrix is spatially selectively and differentially strain-hardened and strengthened near the bonded regions. The spheres of influence of the straining and strain-hardening in the matrix near the bonded regions on one member are caused to significantly overlap similar spheres of influence near the neighboring members.

Abstract: A reciprocating crossfire set of rinsing means rinses the surface of a glass sheet while maintaining a uniform thickness of rinsing medium in an area on the glass surface where a subsequent spraying operation is to be carried out. The rinsing means are angled obliquely downward, rearward and outward, and rinse water or other medium is supplied at a rate sufficient to force excess rinsing medium off the side and the trailing edge of the sheet, rather than being delivered into the spray area or accumulated along its trailing edge portion. The uniform thickness of rinsing medium prepares the substrate for receiving a more uniform transparent metal-boron coating in the spraying operation that follows.
