Abstract: Process and apparatus for reduced noise reception of frequency modulated electromagnetic signal transmissions employing at least three spatially displaced receiving channels. The received at least three signals are continuously sampled at a high frequency, and the sampled signals are compared to each other. As a result of this comparison one sampled signal is selected and used for the reconstruction of the original transmission. The process is repeated for each sampling.

Abstract: A novel process for forming protected, electrographic image on a substrate is disclosed. An electrographic element used in the process comprises a supporting layer, a conductive layer, and a dielectric layer. A protective element used in the process comprises a temporary support layer, a protective layer, and an adhesive layer. The novel electrographic imaging process comprises the steps of producing a toned electrographic image on the surface of the electrographic element; applying and adhering the adhesive layer of the protective element to the toned electrographic image to form an imaged composite; removing the supporting layer from the composite to uncover the conductive layer; pressure laminating the final substrate to the conductive layer; and then removing the temporary support layer from the protective layer to form the protected, electrographic image on the substrate of choice.

Abstract: A novel two step process is disclosed for the manufacture of protected, distortion-free, full-color electrographic images for use on large format posters, billboards and the like. A novel electrographic element, which is used in the process, comprises a carrier layer; optionally, a protective layer; a conductive layer; a dielectric layer; and a substantially tack-free, adhesive layer which is activated at a pressure and a temperature which is above ambient pressure and temperature of the electrographic element. The novel electrographic imaging process comprises: A) producing a toned image layer on the surface of the electrographic element, so that the toned image layer is adhered to the surface of the adhesive layer; and B) pressure laminating the receptor substrate at an elevated temperature to the toned image layer to form the completed electrographic image.
