Abstract: 1,237,569. Radiographic film. INTERNATIONAL POLAROID CORP. 16 July, 1968 [21 July, 1967], No. 33918/68. Heading H5R.  In preparing a radiograph there is exposed to the ionizing radiation a product comprising a support layer carrying an intensifier emulsion layer which contains particles of both a luminophor and a photosensitive material, the luminophor being excitable substantially only by penetrating ionizing radiation, and the photosensitive material being sensitive to the radiation emitted by the luminophor, and thereby forming a latent image in the intensifier-emulsion layer and this latent image is developed and formed as a positive image by transferring by diffusion an imagewise distribution of undeveloped photosensitive material to an image receiving layer. Preferably this image receiving layer is part of the product exposed to the ionizing radiation and is positioned on that side of the intensifier emulsion layer remote from the support and the latent image is developed and the positive image formed by spreading processing composition between the intensifier emulsion layer and the image receiving layer. The spreading of this layer may be achieved by positioning a rupturable container between the intensifier-emulsion layer and the image receiving layer. There may be on each side of the intensifier emulsion layer a layer opaque to visible light at least one of such layers being penetratable by the ionizing radiation. It is preferred that a light reflecting layer is positioned between the support and the intensifier emulsion layer. One of said layers opaque to visible light may be positioned between the intensifier-emulsion layer and the image receiving layer and may consist of an alkalipermeable layer of black dye. In a preferred embodiment, the image receiving layer includes its own supporting layer and is adapted to be stripped from the intensifier emulsion layer by positioning between the intensifier emulsion layer and the image receiving layer, a stripping layer of alkali permeable polymeric material. The preferred luminophor is zinc sulphide and it may be used in an amount such that the emulsion layer is opaque to visible light.

Title: Improvements relating to the distribution of pesticidal material especially from aircraft
Inventor: COLLIER KENNETH DOWSETT GOULD
IPC: B64D1/16
Filed: 1953-12-07
Abstract: 761,782. Dropping smoke bombs from aircraft to distribute pesticides. TILTMAN LANGLEY, Ltd., [formerly TILTMAN LANGLEY LABORATORIES, Ltd.]. Dec. 7, 1954 [Dec. 7, 1953 ; March 2, 1954], Nos. 34002/53 and 6125/54. Classes 9 (1) and 9 (2). A smoke bomb for dispersing pesticides comprises a metal  canister 1 containing a smoke charge 34 above which is a resilient metal diaphragm with a central depending flange 3 supporting time fuze mechanism for ignition of the charge. An annular chamber above the fuze mechanism contains a parachute. A sleeve 4 extending through the flange 3 houses a spring-loaded firing pin 5 and a percussion cap 7 connected to a length of quickmatch 8 embedded in the charge 34. A detent lever 10 engaging the firing pin is held in the safety position by clockwork mechanism 9, the lever being locked by an arming pin 13. To set the fuze, a graduated ring 18, which engages the lever 10, is turned to the appropriate reading, operation of the clockwork being prevented by a timing-pin 20 which is withdrawn before dropping the bomb. Through a cruciform lid 15 passes a cord 14 connecting the arming pin to a cord 16 attached to the parachute 17, which is in turn connected by lines 27 to a spring clip 29 attached to the lid 15. A cardboard ring 25, snapped into grooves 26 holds the parachute in the chamber 22. Before dropping the bomb from an aircraft, a loop 32 of the cord 16 is hooked to the aircraft, so that as the bomb falls the pin 13 is pulled out and the cord 16 tears the ring 25 from the chamber 22 and withdraws the parachute. When the lines 27 tauten, a weak link 30 connecting the cord 16 to the parachute is broken and the parachute opens. When the ring 18 has rotated until a notch 19 registers with the lever 10, the lever disengages from the ring and frees the striker. Smoke from the charge escapes through openings 33. Belt conveyers 35 carry the bombs 37 to an outlet 38 in the bottom of the aircraft. A flexible tube may be filled with the pesticide, the tube being of such a material that it is destroyed by the burning powder. The charge may be distributed at intervals along the tube intervening sections being used to transmit combustion. The tube may be of flattened or circular section and a fuze may be placed at one or both ends or at intermediate positions. The tube may be stored in coils or on reels, the fuze being attached to a parachute. Several insecticide bombs may be connected together by instantaneous fuze or by electric cable, an igniter being placed at each end of the connecting means.

IPC: C09B62/08
Filed: 1954-11-29
Abstract: The invention comprises dyestuffs, which in the form of their free acids, are of formula <FORM:0785222/IV (b)/1> where A may contain substituents other than hydroxy and amino groups, X is H or a substituent other than halogen and of Y1 and Y2 one is H and the other H or SO3H. They are made either by diazotizing an appropriate 2-sulphoamino-benzene and coupling with the required azo component or by condensing equimolar quantities of cyanuric chloride, preferably in an aqueous medium, and the necessary benzene-azo-naphthalene dyestuff.  The heterocyclic component may be made in situ and all reactions are preferably effected at below 5 DEG  C. to avoid side reactions and, also for this reason, the dyestuffs are preferably isolated at pH 6.4-7.8 and dried at 20-40 DEG  C. in the presence of buffering agents which maintain a pH of about 6.5, e.g. mixtures of disodium hydrogen phosphate with sodium or potassium dihydrogen phosphate.  Specified diazo components are aniline-2-mono- and -2,5-di-sulphonic acids, 3-aminobenzotrifluoride-4-, 4-chloro - 5 - methyl-, 5 - chloro - 4 - methyl-, 4-acetylamino-, 4-chloro-, 4-methyl- and 4- and 5 - methoxy - aniline - 2- and 2,4 - dimethyl-, 3 - acetylamino-, 3 - methyl and 2,4 - dimethoxy-aniline-6-sulphonic acids.  Azo components are derived from 1-amino-8-naphthol-6-mono-and -3,6- and -4,6-di-sulphonic acids.  The dyestuffs as their alkali metal salts yield red colours on cellulosic textile material, e.g. when they are impregnated with a solution of the dyestuff and after-treated with an acid-binding agent such as caustic soda in an aqueous medium containing an electrolyte such as sodium chloride or sulphate or when printed with a paste containing the dyestuff and a substance such as sodium bicarbonate, which on subsequent heating or steaming, liberates an acid-binding agent. Examples are provided illustrating the preparation of the dyestuffs and their use in dyeing cotton, the components used being chosen from those listed above. Specification 209,723, [Class 2 (iv)], is referred to.
