  • Patent number: 4465704
    Abstract: The recording of surface topology is obtained by first bringing the surface into contact with the imaging material-coated side of a dry process dispersion type recording film comprising a transparent substrate on which is coated a very thin, high optical density, opaque body of imaging material, preferably coated with a thin abrasion-resistant protective layer. Radiant energy is then momentarily directed to the imaging material through the transparent substrate. When the heat generated by the absorbed radiant energy is above a given threshold value at a particular location of the imaging material, the material deforms and disperses thereat to form connected or unconnected globules with spaces therebetween. Upon termination of the radiant energy, the dispersed material becomes frozen in place.

  • Patent number: 4271257
    Abstract: An imaging film, and a method of making it, comprising a flexible plastic substrate having a thin, high optical density, continuous layer of bismuth, or an alloy of bismuth, deposited on a surface thereof. The bismuth layer has a roughened outer surface. To this roughened surface a layer of a photoactive material is applied which serves as a photoresist as well as a protective overlayer for the bismuth. The photoactive material may be positive or negative working. A layer of a developable photographic emulsion may be applied to the photoactive material layer to impart camera speed to the imaging film. The photoresist side of the film has a non-shiny, essentially non-reflecting black surface which resembles the appearance of developed silver halide films. The substrate side of the film, on the other hand, has a metallic appearance which is easily distinguishable from the photoresist side. This feature of the film enables an operator to readily ascertain the photoresist side of the film and speeds plate making.

  • Patent number: 4267261
    Abstract: In a method for full format imaging, a solid continuous film of a dispersion imaging material is provided on a substrate and it disperses into a discontinuous film comprising space globules and free space therebetween through which free space light can pass where it is subjected to a short pulse of high intensity non-coherent radiant energy in an amount sufficient to increase the absorbed energy above a certain threshold value. The short pulse of high intensity non-coherent radiant energy is applied to the solid continuous film, through a mask, simultaneously and substantially evenly in a full format pattern to a plurality of areas thereof to cause simultaneous and substantially even dispersion of the continuous film in those pattern areas into a discontinuous film comprising the spaced globules and free space which are substantially evenly distributed in those pattern areas and through which free space light can pass.

  • Patent number: 4232966
    Abstract: A device for supporting a contact lens in any desired position with relation to an optical instrument to enable the parameters of the lens, especially the curvature and/or the axes of the surfaces of the lens, to be analyzed. The device comprises a base member which is provided with means for attaching it to an optical instrument such as a keratometer or radiuscope. The base member has an extension which carries a receptacle or container for a solid, resilient, elastomeric, lens-engaging material to which the concave and convex surfaces of a contact lens are removably adherable by slight pressure. The material is dry to the touch, non-blocking (i.e., no adhesion between the lens and the lens engaging material) and non-smearing with respect to the surface of a contact lens, and has a refractive index such that it eliminates reflection from the surface of the lens in contact with the material. A lens, when adhered to the material, can be oriented in any desired plane with respect to an optical instrument.
