The fitting assembly comprises a first fitting 26 having an outwardly extending flange 27, an outer annular wall 28 which fits inside the neck 23 of the bottle and an inner annular wall 36 surrounding the spout 44, a second fitting 29 having an annular wall which fits inside the wall 28 of the first fitting, and an outwardly extending flange 31, and a third fitting 38 which fits inside the wall 36 of the first fitting and has a tubular outlet 46. O-ring seals 33 and 42 are received in annular spaces 32 and 41 respectively between the upper end of the wall 28 and the flange 31 and between the upper end of the third fitting 38 and a flange 39 at the upper end of the wall 36. In use, compressed air supplied to the inlet 51 from a supply line 52 passes into the annular recess 48 and thence through the spout 551 into the tube 54 so that air pressure above the liquid in the bottle causes liquid to be discharged through the spout 44 and the outlet 46. Air is discharged through the outlet 49, and tubes 47, 53 connected to the outlets 46 and 49 respectively convey liquid and air to the spray dispenser (13), Fig. 1 (not shown). The tubes 47, 53 and the air supply line 52 are confined within an elongated guide-member 58 attached to the first fitting 26 and the inverted bottle is mounted on a stand which includes a metal supporting tube 20 surrounding the cap assembly. The ends of the spouts 44 and 551 are coplanar with the mouth of the bottle so that a closure cap (512), Fig. 15 (not shown) can be fitted on the bottle in place of the cap 22 and the fitting assembly. Fig. 16 (not shown) depicts a device in which the tube 54 is replaced by a shorter closed tube (254) having a slit (261) which acts as a valve permitting flow of air into the bottle.
Patent GB-351271-A (GB)
IPC: C01D9/04
Filed: 1930-07-11
Abstract: In the production of potassium nitrate by the double decomposition of potassium sulphate and calcium nitrate, double salts such as syngenite (K2SO4, Ca SO4, H2O) and potassium pentacalcium sulphate (K2SO4, 5 Ca SO4, H2O) ar formed as byeproducts.  This disadvantage is avoided in a cyclic process in which potassium chloride, nitric acid, ammonia and carbon dioxide are the raw materials and potassium nitrate and ammonium chloride the products, whilst gypsum is added and its calcium and sulphuric acid kept in circulation.  The process comprises the following steps: (i) stirring a solution of ammonium chloride and carbonate (obtained in (v)) with gypsum (obtained in (iii)) and separating the precipitated calcium carbonate; (ii) adding potassium chloride to the liquor from (i), treating with ammonia and separating potassium sulphate; (iii) treating a mixture of the calcium carbonate and potassium sulphate with nitric acid to produce gypsum and potassium nitrate, the former being separated and the latter obtained by evaporating the solution; (iv) separating part of the ammonium chloride in the liquor from (ii) by cooling; (v) neutralizing the remaining liquor from (iv) with carbon dioxide to produce the starting material of (i).  In a modification, steps (i) and (ii) are combined, the ammonium chloride-ammonium carbonate solution being successively stirred with gypsum and potassium chloride and treated with ammonia, and the mixture of potassium sulphate and calcium carbonate so formed treated as in (iii), In another modification the greater part of the potassium nitrate is separated from the liquor of (iii) by cooling instead of evaporation, and the mother liquor is used for dissolving further quantities of potassium sulphate for treatment with calcium carbonate and nitric acid.

Title: Pressurized fog producing device
Inventor: COLLINS DEAN E
IPC: B05B7/24
Filed: 1970-05-01
Abstract: 1,271,886. Spray producers. ROOT-LOWELL MFG., CO. 1 May, 1970, No. 21045/70. Heading B2F. A fog producing device consists of a chamber .10 in which there is a motor-driven fan or blower effective to draw in air from the left side of the housing 12 and discharge it through a nozzle 74 connected to the opposite end of the chamber, this chamber being connected by a pipe 16 to a liquid container 28, the pipe passing through an apertured tube 52 sealed to both chamber housing 12 and the container with a part-cylindrical sleeve 62 around it which can open or close a bleed valve 58, the pipe 16 extending into chamber 10 and through conduit 70 to have its outlet adjacent the nozzle. The tube 52 is sealed to the container 28 via a seal 22 which is releasable so that the container and chamber can be separated. In operation, with the bleed valve 58 fully open, only atmospheric pressure acts on the liquid in the container 28, the flow of air through chamber 10 to the nozzle 74 past the outlet of tube 16 aspirates liquid into the air stream and a fine fog or mist is discharged through the nozzle, the character or quantity of which being optionally controlled by a valve 78 at the nozzle, which valve controls air flow from apertures surrounding the nozzle. The nozzle 74 contains a venturi passage the recovery angle of which determining the conical shape of the discharge. To produce a less fine fog or mist containing larger particles the sleeve valve is closed, this increasing the pressure on the liquid in the container 28, producing a combined aspirating action and pressure feed of liquid through pipe 16, this increasing the rate of liquid entrainment in the air stream. Intermediate positions of the sleeve valve 62 can produce intermediate liquid particle sizes. The apparatus may be used for spraying insecticides, pesticides, deodorants and scenting materials.

Title: Improvements in or relating to the introduction of vapour fillings into sealed enclosures
Inventor: ALLWOOD WILLIAM NORMAN
IPC: H01J9/395
Filed: 1962-06-05
Abstract: 961,245. Introducing gas and vapour fillings into electric lamp bulbs. GENERAL ELECTRIC CO. Ltd. May 27, 1963 [June 5, 1962], No. 21712/62. Heading H1F. In a method of introducing the vapour into the enclosures of a device which is to contain gas and vapour and to be sealed, the filling gas is fed unidirectionally along a path which passes over a quantity of a substance capable of producing the vapour on heating and then through the enclosure, the substance being at first maintained at a temperature such that little or no vapour is contained in the gas which is then used for flushing impurities out of the enclosure and is subsequently heated so that a considerable quantity of vapour passes into the enclosure with the gas stream and the enclosure is sealed off whilst it contains a filling of gas and vapour. Apparatus for carrying out the method for use in making electric incandescent lamps containing a filling of argon and iodine vapour consists of a source 1 of argon leading through a control valve 2, a gauge 3 and a drier 4 to a closed vessel 5 containing iodine crystals I. A pipe 12 surrounded by a heating coil 18 passes from the vessel 5 to a compression head 6, a narrow capillary tube 11 of platinum extending from the pipe 12 through the exhaust tube 7 of a lamp 8, the tube 7 being held in a rubber gland 9 in the head 6. A tube from the head 6 passes to atmosphere through an iodine trap 12<SP>1</SP>. The vessel 5 is surrounded by an outer jacket through which hot or cold liquid can be passed from sources 15, 16 by means of a control valve 17. Flushing of the lamp is effected by the flow of argon while the vessel 5 is maintained at a low temperature and filling is effected by raising the temperature of the vessel 5 so that iodine vapour is added to the argon, the vessel 5 being cooled again after the exhaust tube 7 is sealed off. If desired, the supply of iodine to the vessel 5 may be maintained by passing the argon through a reservoir containing iodine crystals and maintained at a temperature sufficient to produce iodine vapour, which condenses in the vessel 5 during the periods when this is cooled.
