Title: Improvements relating to processes for preventing rusting of ferrous metals
IPC: C23C22/83
Filed: 1933-09-05
Abstract: An anti-corrosive coating is formed on ferrous metal by immersing the metal first in a bath containing phosphoric acid and then in a bath of oil containing graphite in colloidal suspension. The metal may be treated in a bath containing 1/2 -1 per cent phosphoric acid, washed to remove all traces of acid, and then immersed in a colloidal suspension of graphite in oil, preferably linseed oil, the suspension containing 1 fluid ounce of graphite per gallon of oil.  The graphite fills the pores in the metal and in conjunction with the phosphate coating protects the ferrous metal from corrosion.  According to the Provisional Specification, colloidal suspensions of relatively inert solid substances other than graphite may be used.

Abstract: 713,858. Coating with metals. CATHODEON, Ltd. Jan. 26, 1953 [Oct. 26, 1951]. No. 25090/51. Class 82 (2) [Also in Group XXXVI] The target electrode in a photo-conductive pick-up tube is produced by applying a selenium layer by sputtering, or vacuum deposition on to a transparent conducting signal plate 5, on the internal glass face 3 of the tube, while this is maintained at a temperature of between 30‹C. and 40‹C. The process improves the photoconductivity effect of the selenium. The glass face 3 is secured to the tube by a metal ring 4 of "Kovar" or "Telcoseal I" (Registered Trade Marks), material which serves as the connection to coating 5 which is preferably of cadmium oxide. An evaporating source 6 may be used to apply the selenium which may be extracted from the tube through neck 8 which is then sealed off. The temperature of the glass face 3 may be maintained at the required temperature by means of a jet of hot air from pipe 7. A coating 9 forms the final anode for use with electron gun assembly 2.

Title: Photographic silver halide materials with wide exposure latitude
Inventor: MARCHANT JOHN CARL
IPC: G03C1/46
Filed: 1969-05-16
Abstract: 1275069 Photographic silver halide materials with wide exposure latitude EASTMAN KODAK CO 16 May 1969 [20 May 1968] 25122/69 Heading G2C A photographic material comprises a support carrying two light-sensitive silver halide emulsion layers having different photographic speeds but sensitive to the same region of the spectrum, the slower layer containing a non-diffusible photographic image-forming coupler and a non- diffusible development-inhibitor-releasing (DIR) coupler, the faster layer containing a non- diffusible photographic image-forming coupler and having a higher effective photographic speed than said slower layer. The faster layer preferably has an effective photographic speed at least 0À6 log exposure units higher than the slower layer. Many examples are listed of couplers. The DIR coupler preferably carries a heterocyclic monothir radical in its coupling position. Other DIR couplers include α-{3-[α-(2,4-di-tertamylphenoxy) butyramido]benzoyl}-α-(2- aminophenylazoxy)-2-methoxyacetanilide and α-{3-[γ-(2,4-di-tert-amylphenoxy)butyramido]- benzoyl-α-(2-amino-4-methylphenylazoxy)-2- methoxy-acetanilide. The light-sensitive silver halide emulsion layers may be separated from the support by a non-image recording silver halide emulsion layer in which the silver halide grains have an average diameter of less than 1 micron. The non-image recording layer may have a thickness of 10-40 microns, and reduces image spread. Both the slower and faster layers may contain cyan-forming couplers and the DIR coupler may form a cyan dye (see Example). The light-sensitive silver halide emulsion layers may be separated from the support by an antihalation layer. The DIR coupler in the slower layer extends exposure latitude and reduces contrast. These materials can record images of vastly different intensity in close geometrical proximity with minimal image spread, and exhibit excellent sharpness. They produce high contrast records of faint images and low contrast records of bright images. Reference has been directed by the Comptroller to Specification 953454.
