Abstract: Transparent, refractory coatings and methods for their application to environmentally exposed substrates are disclosed. The coatings can be deposited over organic decorative materials, which generally prevent application of hard, protective, inorganic materials due to emission of exudates and vulnerability to excessive heat. The coatings are applied using plasma-enhanced chemical-vapor deposition techniques that reduce reaction temperatures and produce multilayer structures that seal organic exudates before a final layer of coating is applied, such multilayer protective coating structures being particularly suitable for protecting automobile bodies and the like against degrading external forces.

Abstract: Sputtering apparatus in which a substrate passes through a sputtering chamber in a continuous rectilinear movement. The chamber is formed in a coffer-like vessel which has a closure and a body that are brought together into a sealing engagement to form the chamber. There is an air lock at opposite ends of the coffer for the substrate to enter and leave.The sputtering conditions are provided by suitable gases, pumps, electrical connections and the like, these being admitted or led into the chamber. Electrode pairs are provided, one of each pair being mounted on the closure the other in the body to give good access thereto. The one mounted on the closure may be the anode and the other the cathode or vice versa. The sputtering is carried on with r.f. power.The closure may be hinged.For sputtering selectively, masks may be interposed between the targets and the anodes. Such masks will result in strip sputtering.

Abstract: Electrophotographic medium which comprises a multilayer structure of materials for imaging radiant energy patterns at high speed and with high sensitivity of a degree capable of meeting and exceeding the sensitivity of silver halide film, with greater resolution than that of silver halide film of the high speed type.A method of using electrophotographic film to achieve high sensitivities and speeds.The medium comprises a transparent substrate, ohmic layer and coating of photoconductive material, all of which form a modulating structure for the radiant energy that is adapted to be projected through the substrate; a dielectric layer intimately bonded to the surface of the photoconductive coating and a conductive electrode in intimate contact with the dielectric layer.The use of the electrophotographic medium does not require initial charging; hence no means for effecting this are required.

Abstract: Electrophotographic medium which comprises a multilayer structure of materials for imaging radiant energy patterns at high speed comprising a transparent substrate, ohmic layer and coating of photoconductive material, which form a modulating structure for the radiant energy projected through the substrate; a dielectric layer intimately bonded to the surface of the photoconductive coating and a conductive electrode in intimate contact with the dielectric layer. The dielectric layer constitutes the storage medium for the image which is produced in electrostatic charge form and, the medium is capable of retaining latent images for a very substantial length of time.The use of the electrophotographic medium does not require initial charging; hence no means for effecting this are required. Further, the speed of the medium is so high compared with all other media that extremely low energy levels can provide sufficient contrast to produce images.The structure as described is used by connecting a d.c.

Abstract: Electrophotographic medium which comprises a transparent substrate, ohmic layer and coating of photoconductive material, all of which form a modulating structure for the radiant energy that is adapted to be projected through the substrate; a dielectric layer (storage medium) intimately bonded to the surface of the photoconductive coating and a conductive electrode in intimate contact with the dielectric layer. The structure is used by connecting a d.c. voltage across the outer electrode and the ohmic layer and projecting the image onto the electrophotographic medium from the bottom surface of the substrate. The charge image appears on the dielectric layer. The charge image is read out with an electronic beam or toned and fixed or transferred. During use the electrode is brought into intimate contact with the dielectric layer and removed after forming the charge image in order to enable the medium to be processed further without the electrode.
