Title: Improvements in or relating to colour photography
IPC: G03C7/30
Filed: 1944-05-12
Abstract: 576,889. Colour photography. HARRISON, G. B. May 12, 1944, No. 9085. [Class 98 (ii)] Photographic material comprises a substantially colourless transparent support carrying in superposition a red-sensitized silver halide emulsion layer containing a colourcoupler, a green-sensitized silver halide emulsion layer containing a colour-coupler, a yellow filter layer containing a colouring matter which is stable to treatment with ordinary developing baths, but which is capable of being discharged, and a blue-sensitive silver halide emulsion layer not containing a colour-coupler. The yellow colouring matter may be the free base of Auramine or Thioflavine T or the dyes described in Specification 555,642. In an example, a support is successively coated with a gelatino silver iodobromide emulsion redsensitized with 3: 3<1>: 9 - trimethyl - 5 : 5<1-> dichlorothiacarbocyanine bromide and containing 1 : 2-hydroxynaphthoyl-p-dodecylanilide, a gelatino silver iodobromide emulsion greensensitized with 1 : 1<1> - diethyl - 2 : 2<1> - cyanine iodide and containing 1-(m-octadecoylaminophenyl)-3-methyl-5-pyrazolone, a gelatin filter layer dyed with Auramine base, and a bluesensitive gelatino silver iodobromide emulsion. After exposure, development in a metolhydroquinone developer containing a small proportion of silver halide solvent, and washing, the material is colour developed, washed, bathed in an acetic acid solution to remove the Auramine, washed, bathed in a potassium iodide-thiourea solution, washed, bathed in an Auramine O solution, washed, bathed in a silicotungstic acid solution, washed, treated in Farmer's Reducer, and washed. In a modification, the silver halide in the blue-sensitive layer is re-exposed and developed in a colour developer containing diacetoacetbenzidide and the auramine in the filter layer may be removed before or after this treatment. In a further modification, the silver halide in the bluesensitive layer is converted to silver sulphide by treatment in an aqueous ethyl alcohol solution of sodium sulphide (the auramine in the filter layer being removed before or after this treatment), the material is treated in Farmer's Reducer, and after washing the material is treated in a cadmium nitratepotassium cyanide solution to convert the silver sulphide image to yellow cadmium sulphide. The colour-coupler may be selected to give a false-colour material. Specification 556,003 also is referred to.

Title: Sprinkling device
IPC: B05B3/06
Filed: 1929-03-22
Abstract: 330,330. Orr, F. C. March 22, 1929. Rotary apparatus; splashing apparatus. - A sprinkler having a slow intermittent rotary movement comprises a. tubular member 11, Fig. 1, rotatably mounted in a stand pipe 10 and carrying an inclined tube 12 terminating in a nozzle. Pivoted on a bracket 14 on the tube 12 is an arm 16, movement of which is limited by a stop 18, and carrying at one and a bent tube 4 and at the other a weight 17. Water from the nozzle 13 passing through the tube 4 gives a reaction causing the apparatus to rotate, when centrifugal force raises the weight 17 causing the tube 4 to be withdrawn from the jet thus stopping the rotary movement. Fig. 6 shows a modification by which a slow intermittent movement is given for part of the rotation and a rapid continuous movement for the rest. In addition to the weighted arm 16 carrying a deflector 22 a second arm 25 is pivoted to the tube 12 carrying an inclined plate 27 which is normally in the path of the jet the reaction of which rotates the apparatus. An adjustable cam 30 withdraws the plate 27 as shown in dotted lines when the deflector 22 is brought into action to give intermittent movement. Fig. 10 shows a form in which a curved plate 33 is mounted on the arm 16 and carries a lug 34 of the cross-section shown in Fig. 11 against which water from the jet 13a impinges.

Title: Improvements in or relating to gas-mixture fractionation apparatus
IPC: B01D3/42
Filed: 1956-03-27
Abstract: 789,051. Cold separation of gas mixtures. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. March 27, 1956 [March 30, 1955], No. 9530/56. Class 8(2). In a gas mixture, e.g., air fractionating apparatus comprising a column 1 from which gaseous nitrogen passes along a duct 17 to a heat sink, e.g., the condenser space of a gas refrigerator 19 of the reversed hot gas engine type wherein the nitrogen is condensed and flows down a duct 21 and is forced up a duct 23 to act as reflux by means of vapour bubble pump action controlled by the level of liquid in the boiler 2, and from which apparatus product liquid nitrogen is withdrawn, e.g., through a branch 28 of the duct 21 the rate of withdrawal of product liquid nitrogen is controlled by means, e.g., a port 27 located at the normal level of liquid 26 in the duct 21. In operation air at substantially atmospheric pressure is drawn by the subatmospheric pressure within the column through a duct 15 past cold apertured fins 12 on which easily condensible impurities are deposited and through a duct 16. Energy for the bubble pump is derived by heat conducted from the boiler 2 along an apertured duct 6 and a metal strip 24 ; the duct 6 together with a duct 5 serving to connect the vapour space of the boiler 2 with the column 1 through a valved duct 8. In the event of the level in the boiler rising above normal, i.e., just above the bottom of a tube 4 which connects the liquid space of the boiler to the column, the apertures 25 in duct 6 become closed, the oxygen content in the duct decreases and hence the temperature is decreased resulting in a lower pumping action which in turn results in liquid nitrogen being transferred through the port 27 into the branch 28 to a receptacle 30. Lowering of the boiler level results in increasing the bubble pump action, cessation of overflow of liquid nitrogen through the port 27 until the extra reflux supplied to the column restores the level in the boiler 2. In a modification product nitrogen is withdrawn directly from the condenser of the refrigerator through a valved duct controlled by variations in an electrical resistance located at the normal liquid level on the downpipe.

Title: Improvements relating to the production of fibrillated monofilaments
Inventor: ATKINSON EDWARD BROWELL
IPC: D01D5/42
Filed: 1964-03-06
Abstract: 1,104,694. Making fibrillated monofilaments. BAKELITE XYLONITE Ltd. 8 June, 1965 [6 March, 1964], No. 9530/64. Heading B5B. Fibrillated monofilaments are made by treating with an agent which selectively acts on one of the polymer phases of the monofilament an oriented monofilament comprising an intimate mixture of two or more polymers of which two or more of the polymers are incompatible with one another in the proportion present in the mixture, flexing the treated filament (particularly by crimping it by a mechanical process), and if necessary, removing the agent. The effect of treating the monofilament with the selective agent is to cause the monofilament to be more easily fibrillated after it has been flexed. The action of the agent on the monofilament may result in at least one but not all of the polymer phase of the monofilament (said phase consisting of one or more polymers) becoming relatively soft, flexible, waxy or liquid, while the other component of the monofilament (which component consists of one or more polymers incompatible with the first component) remains unaffected or relatively unaffected by the treatment or relatively rigid. When one of these components is nylon, a liquid ketone such as acetone may be used. Two polymers are defined as being mutually incompatible if, when mixed in the proportions in which they are present in the monofilament and at a temperature at which they are both in a soft plastic or liquid condition, they do not form a homogeneous mixture and are not mutually soluble. The selective softening of the filament may be effected as follows: (1) by immersing the filament in a solvent which dissolves one component of the filament and not the other, the time of immersion being only sufficient to soften the soluble component; (2) by heating the filament to a temperature at which one component of the filament is softer than the other; (3) by treating the filament with a chemical reagent which makes one component harder or softer than the other (e.g. a cross-linking agent or a plasticizer respectively). The monofilaments may be produced by melt-spinning the following polymer mixtures: (1) polystyrene and polyethylene oxide; (2) polystyrene, styrene/ acrylonitrile copolymer and polyethylene oxide; (3) polyethylene and polyethylene oxide; (4) nylon type 6 and low molecular weight polyethylene; (5) nylon type 6 and a low molecular weight polymer of #-pinene; (6) high density polyethylene and cellulose acetate; (7) isotactic polypropylene and cellulose acetate; (8) polypropylene and low molecular weight polystyrene; (9) polypropylene and polyethylene oxide.
