Title: Improvements in or relating to blowpipe burners for cutting, welding and similar metal working operations
IPC: B65C11/04
Filed: 1934-09-13
Abstract: 448,908. Blowpipe burners. LINDE AIR PRODUCTS CO., 30, East 42nd Street, New York, U.S.A. Sept. 13, 1934, No. 26322. Convention date, Sept. 13, 1933. [Classes 75 (i) and 75 (iii)] In a blowpipe burner for welding, cutting, deseaming, and similar metal-working operations, the oxygen or other combustion-supporting gas is mixed with air before being mixed with the fuel gas and the flow of oxygen and the fuel gas is controlled by valves operated by a single means. In the burner shown, a single lever 96 operates the stems 95 of two diaphragm valves 48, 76 controlling the flow of oxygen and acetylene respectively from hose nipples 15, 69 to the heating gas passages 90 in the blowpipe nozzle 38. The oxygen on leaving the valve 48 enters an injector nozzle 54 in a bore 52 in the valve body B and passes with air aspirated through a shielded bore 56 through a throat 59 to a tube 60 which extends to a bore 61 in the blowpipe head He. The oxygen and air mixture then returns through a tube 62 to the valve body B where it passes through a mixer nozzle 67 in a bore 64 which is connected to the valve 76 through an exchangeable metering plug 77. The acetylene gas and air mixture is then conveyed to the nozzle 38 through a throat 82, an expansion chamber 81, and a tube 80. The length and volume of the tubes 60, 62 are such as to ensure that flashbacks will be extinguished before reaching the air inlet 56. The operating arm 96<a> of the lever 96 is cut away so as to open the oxygen valve,48 sooner and permit its closure by the spring 94 later than the acetylene valve 76. Oxygen is supplied to the cutting gas passage 41 in the nozzle 38 on a lever 27 being pressed to operate a plunger 31 to raise a spring-pressed valve V from its seating 18, thereby allowing the oxygen to pass through a tube 34 to a bore 35 and cavity 39 in the head He. The bore 35 is fitted with a constricting plug 37 limiting the volume of oxygen delivered. The oxygen and acetylene inlets to the valve body are fitted with screw-down stop valves 44, 72. The acetylene valve 72 is opened fully at starting and the oxygen valve 44 is then adjusted till a flame of the character desired is obtained.. A pilot burner P for igniting the heating gas mixture is connected by a tube 102 to a passage 101 in the valve body B, the passage 101 being connected to a passage 74 conveying acetylene to the valve 76. A bracket 103 clamped to the tube 80 carries the burner P which is fitted with a double screen 108 to prevent clogging of the fuel nozzle 109. A metering orifice 112 determines the size of the flame which is protected by a shield 113. The lever 96 and the operating button 28 of the lever 27 are arranged on opposite sides of blowpipe so as to be operable by the fingers and thumb of the operator's hand gripping the blowpipe handle H. The Specification as open to inspection under Sect. 91 comprises also the subject-matter of Specification 449,003. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to methods of thickening latex
IPC: C08K3/30
Filed: 1932-09-22
Abstract: Latex is thickened to any desired degree without coagulation by the addition thereto of a colloidal sulphide, and a fixed alkali, preferably zinc sulphide and sodium hydroxide.  Auxiliary thickeners and stabilizers such as soap, glue, may also be added. The colloidal sulphide is preferably formed in situ in the latex. According to an example, to 286 parts of normal latex (35 per cent solids) is added 10 parts of a 10 per cent sodium oleate solution, 6 parts of sodium polysulphide solution, and a paste consisting of 0,25 glue, 5 water, 5 zinc oxide and 6 sodium polysulphide solution.  To this mix is added 2,15 parts of a 25 per cent solution of sodium hydroxide.  The sodium polysulphide solution consists of 100 parts Na2S.9H2O, 50 parts sulphur, and 46 parts water.  If the films obtained from this latex are to be vulcanized, additional sulphur is added.  The viscosity depends upon the amount of alkali added, and may be reduced at any time by the addition of a weak acid, such as boric.  Ammonium or potassium polysulphides, or a solution of sulphur in sodium hydroxide may replace the sodium polysulphide.

Title: Improvements in and relating to phosphate fertilizers
Inventor: HUDSON JOHN HERBERT
IPC: C05B7/00
Filed: 1951-11-19
Abstract: Granular fertilizers consisting mainly of dicalcium phosphate and ammonium nitrate are prepared by reacting with continued agitation, phosphate rock with sufficient nitric acid to produce monocalcium phosphate and calcium nitrate, then adding mono-ammonium phosphate and ammonia, the former being sufficient to decrease the molar ratio of nitrate to phosphate radicles to about 4 to 3, and the latter being sufficient to ensure conversion of all the monocalcium or mono-ammonium phosphate and calcium nitrate to dicalcium phosphate and ammonium nitrate, and finally adding dried recycled material to reduce the water content to between 7 and 12 per cent. by weight. The nitric acid employed is preferably a 45 to 65 per cent. by weight aqueous solution.  The addition of the ammonia, which may be gaseous, an aqueous solution or anhydrous liquid ammonia may be made in stages, preceding, together with, or subsequent, the addition of mono-ammonium phosphate.  The latter may be added as aqueous solution, but preferably as crystals.  The quantity of ammonia employed is p  preferably 5 per cent. in excess of that required to secure the conversion to dicalcium phosphate and ammonium nitrate, but a large excess should be avoided since reversion may occur. According to an example, phosphate rock was reacted with 50 per cent. nitric acid in a paddle mixer for 5 minutes, after which some aqueous ammonia was added.  A solution of mono-ammonium phosphate at 90 DEG C. was then added with stirring; the temperature of the mass was 43 DEG  C.  More aqueous ammonia was then added and after 15 minutes dried recycled material was added to reduce the moisture content to 11 per cent., after which, with continued mixing, granules were obtained which were dried at 80 DEG  C.  The process may be batch or continuous.  The mono-ammonium phosphate is preferably prepared by reacting phosphate rock similar to that used in the main reaction, with sulphuric acid and ammonium sulphate.  After separating at least some of the gypsum the solution may be neutralized with alkali, suitably ammonia, and concentrated or evaporated.

A device for turning a row of cigarettes comprises feeding means to feed the cigarettes sideways and a rotatable member with a plurality of angularly disposed cigaretteholding devices arranged to receive the cigarettes one at a time and carry them in overlapping relationship generally lengthwise in an arcuate path about the axis of the member so as to reverse theirorientation. In Figs. 1 and 2 a double row of cigarettes, formed by bisecting cigarette and mouth-piece assemblages on a grooved drum 1, are transferred to a roller 5, which cooperates with a plate 6 to restore the mouthpieces to circular shape, and then on to chains 11 with cigarette receiving recesses which deliver the cigarettes to a turning station at which one row of cigarettes proceeds directly on to a catcher band 16 whilst the second row is turned through 180 degrees by a transfer member 18 before delivery on to a catcher band 17. The transfer member 18 comprises a rotating disc with inclined cigarette receiving grooves 24 provided with suction passages 25 connected at appropriate periods in the rotation to a suction drum 30. As the cigarettes fall off the chain 11, one end is supported by a guide 36 to tilt the cigarettes approximately to the angle of the grooves 24 in which the cigarettes are held in overlapping relationship by suction until they have been carried round to a ramp 34 down which they roll on to the band 17. In a modification, Fig. 3, the transfer member comprises a rotary drum 103 having flat faces 103 provided with rows of suction holes 107 which co-operate with a helical suction applying groove 109 in a stationary spindle 105 so that suction is applied to the holes 107 in succession from the bottom of each row to the top. As each cigarette is delivered down a ramp 101, it is held to a face of the drum by suction acting on the bottom holes 107 of the appropriate row and as the drum rotates the suction, moving up the row of holes 107, causes the cigarette to roll sideways along the face of the drum so that successive cigarettes can overlap one another, the cigarettes being discharged, after turning through 180 degrees, on to a ramp 113 leading to the catcher band.
