Title: Improvements in or relating to composite cinematograph films
Inventor: MARGUTTI VICTOR LOUIS ALEXANDE
IPC: G03B15/08
Filed: 1955-06-27
Abstract: 787,759. Producing composite pictures. MARGUTTI, V. L. A., and BOWIE, L. G. April 13, 1956 [June 27, 1955], No. 18445/55. Class 98(2) The production of a composite picture includes the steps of photographing a foreground and a plain backing on a single multi-layer colour film and developing said film to a negative; the foreground and backing being independently illuminated so that of the photographically effective rays reaching the colour film those from the foreground include substantially no rays of the same wavelength as those from the backing. The process is preferably carried out by exposing a colour film in a camera to a yellow-lit foreground in front of a blue tint plain backing and developing the film to give a colour negative A.. This negative is printed, if desired through through a blue filter, on high contrast bluesensitive orthochromatic film to give a film B having the foreground silhoueted on a clear background. A second print (film C) is also made from film A, through a yellow filter, on panchromatic film to give a black- and-white foreground image on an opaque background. Finally, negative stack is exposed under film B together with a positive film of the desired background scene and, before development, is re-exposed under film C alone so as to yield on development a negative foreground image on a negative image of the desired background. By the process several foreground scenes may be married to any desired background.

Patent GB-463711-A (GB)
Title: Improvements in or relating to the manufacture of amines
IPC: H04M11/04
Filed: 1935-06-28
Abstract: Amines are prepared from primary, secondary or tertiary aliphatic alcohols containing 10--20 carbon atoms, or from alicyclic alcohols, by treating the alcohols in the vapour phase with ammonia in the presence of a dehydrating catalyst.  The relative proportions of primary, secondary and tertiary amines produced may be controlled by adding one or two of these types of amines to the reaction mixture. Specified catalysts are alumina, thoria, tungsten oxide, metal sulphates and phosphates, silica gel, and zeolites; a description is given of the preparation of granular alumina, for use as a catalyst, from solutions of alum and sodium carbonate.  Preferably, rigid supports impregnated with a dehydrating oxide or mixture of oxides are used.  The supports may be impregnated, with or without preliminary evacuation, with a solution of a metal salt, such as a carbonate or nitrate, capable of yielding a dehydrating oxide when decomposed by heat.  Specified supports are alumina gel, silica gel, active carbon, indianaite, base-exchanging silicates, and the material known under the Registered Trade Mark "Doucil."  The reaction temperature may be 250--500 DEG  C., preferably 300--400 DEG C., and the molar ratio alcohol: ammonia may vary between 1 : 0,25 and 1 : 10, but is preferably 1 : 3.  The reaction may be effected at atmospheric or raised pressure.  In the examples: (1) lauryl alcohol and ammonia are passed at 300 DEG  C. and atmospheric pressure over a catalyst prepared by evacuating silica gel at 400 DEG  C., impregnating the cooled gel in aluminium nitrate solution, and heating the product to 400 DEG  C.; a mixture of mono-, di- and tri-laurylamines is obtained; (2) the process of example 1 is effected at 350 DEG  C.; if mono- and tri-laurylamine are added to the reaction mixture, dilaurylamine only is produced; (3) stearyl alcohol and ammonia, passed at 360 DEG  C. and atmospheric pressure over the catalyst of example 1, yield a mixture of mono-, di- and tri-stearylamines; (4) oleyl alcohol and ammonia, under the conditions of example 3, yield a mixture of mono-, di- and tri-oleylamines; (5) decamethylene glycol and ammonia are passed at 350 DEG  C. and atmospheric pressure over the catalyst of example 1 and yield the corresponding diamine.  Reference is made also to the manufacture of amines from cyclohexanol and naphthenyl alcohols.

Abstract: 532,870. Colour photography. CINECOLOR, Inc. June 28, 1939, No. 18793. Convention date, Aug. 2, 1938. [Class 98 (ii)] A coloured photographic print is produced by printing a colour component negative on to a positive film, developing, toning to Prussian Blue with an iron toning solution, converting the Prussian Blue image to a ferric or ferrous hydroxide image, printing a second component image in registration on the film and developing, reconverting the ferric or ferrous hydroxide image to Prussian Blue, and toning the second image to a different colour. The red component negative may be printed on to a positive film containing a filter dye either from the emulsion or support side, the film is developed and washed, and optionally slightly hardened, and the developed image is toned to Prussian Blue. After washing, the image is converted to a ferric hydroxide image and the remaining silver salt resensitized by treatment with a 2 per cent. sodium carbonate solution. Additional resensitizing agents may be added to the alkaline solution or applied in a subsequent bath, and a small amount of sodium thiosulphate may also be added to the alkaline bath, or a weak solution of sodium thiosulphate subsequently employed, to remove silver ferrocyanide or other silver salt formed in the toning. After washing and drying, the second colour component image is printed on to the film in register with the first image and is developed, washed and optionally fixed. The ferric hydroxide image is reconverted to a Prussian Blue image by a potassium ferrocyanide bath containing formalin followed by a hydrochloric acid bath containing alum. The two baths may be combined. After washing, fixing (if not previously effected), and washing the second image may be toned red in a uranium toning bath or mordanted with an iodine bleaching bath and dyed with a basic dye. A third colour component image may be produced in an emulsion layer on the other side of the support or may be produced in a separate stratum of the emulsion layer. The third image may be chemically or dye toned or produced by the inhibition process. The fixing agent may be any other alkali metal thiosulphate or may be a cyanide or thiocyanate.
