Abstract: A method is disclosed of coating articles of manufacture to prevent corrosion which comprises applying a thermoplastic coating material to the article, applying a layer of fibrous material over the coating material, wetting the layer of fibrous material, and heating the three components, whereby contraction of the fibrous material, during heating, will compress the coating material and counteract its deformation tendencies such that it is well bonded to the article. The thermoplastic coating material is preferably applied in the form of a coating tape comprising the thermoplastic coating material and a thermoplastic adhesive and is used to provide a protective coating for underground pipe.

Abstract: A flexible, e.g. polyurethane, open cell foam sheet is impregnated with a controlled amount of a liquid polymerizable resin system which cures at ambient temperature, and the resin impregnated sheet is immediately chilled at a suitably reduced temperature, e.g. 40.degree. F. or below, to arrest polymerization or hardening. The resulting resin impregnated sheet is stored at such reduced temperature. When needed for adhesive bonding the chilled resin impregnated sheet, cut to the desired pattern or size, is applied between the surfaces of objects to be bonded, e.g. fiber reinforced polyurethane insulation blocks and plywood strips, or such insulation blocks and the steel hull of a liquid natural gas (LNG) container or marine tanker.

Abstract: A micro-capsular material for use as a photographic reproducing medium includes a plurality of micro-capsules distributed over a given surface. Each of the capsules is formed with a mantle of light transmissive material. The mantles may be clear or colored and are advantageously transparent. The contents of each of the capsules includes a photoconductive material as well as a color progenitor or precursor material. Simultaneous exposure of the capsular material to light and high frequency electrical energy causes rupture of the capsule mantles and release of the capsular contents. When an image is focused by a lens onto the surface, selected ones of said capsules are ruptured to thereby result in a reproduction of the image. Dispersing micro-capsules having different color progenitor materials makes possible color photography when means are provided for selectively directing only those component of colored light onto the micro-capsules having corresponding color progenitor materials.

Abstract: A process is disclosed of forming a reversal dye image. This is accomplished by developing an imagewise exposed photographic element with a black-and-white developer and poisoning the developed silver as a redox amplification catalyst for a peroxide oxidizing agent. The undeveloped silver is then rendered developable to form a silver catalyst image pattern. This latter silver image pattern is then used to catalyze the redox reaction of a peroxide oxidizing agent and a dye-image-generating reducing agent, such as a color-developing agent, or a redox dye-releaser.

Abstract: A method of predicting the filter pack correction required to print a color ilm that has been exposed at any illuminant color temperature is provided without the need for a grey card in the scene.This method involves first the experimental determination of the correction filter pack required to produce a grey print from any of the following: the clear unexposed portion of the negative, an image of a continuous wedge or step tablet exposed at a known color temperature on a sensitometer, or the image of a grey card on a roll of film that was exposed at a known color temperature. The red, blue, and green densities of the grey card, or a particular exposure on the characteristic curve, are added to the densities of the correction filter pack to obtain a value called the Total Negative Grey. In the case of the clear portion of the negative, a correction factor of 0.02 green and 0.13 blue must be added to the base fog densities before the densities of the filter pack are added.
