Title: Improvements in the manufacture of carbon from carbon monoxide
IPC: C01B31/00
Filed: 1927-07-05
Abstract: 294,759. Cassel Cyanide Co., Ltd., and Ewan, T. July 5, 1927. Carbon is prepared by the catalytic decomposition of carbon monoxide in the presence of massive catalysts. The catalysts employed in the reaction include iron, nickel, cobalt or their oxides, but iron or mild steel in sheet form are preferably used in the process. The steel may be activated by dipping in fused sodium cyanide, washing in water, reducing carefully in carbon monoxide or hydrogen, and prolonged heating at 500-700‹ C. in carbon monoxide, or by repeated oxidation and reduction in carbon monoxide at 600-700‹ C. The carbon is deposited on the catalytic surface and is removed by mechanical scrapers which do not touch the surface. The carbon produced may contain 3-13 per cent of iron when iron is used as catalyst. The scrapers may be arranged to give a thin film with high iron content and rate of deposition or a thick film with the reverse. In one form, the carbon monoxide is brought into contact with the carbon produced at a temperature varying, according to the pressure employed, e.g. at 20-120‹ C. at atmospheric pressure, thus reducing the iron content of the carbon with the addition of iron carbonyl to the gas. The catalytic decomposition which takes place at a higher temperature e.g. 300-600‹ C. may be carried out in an iron tube, or a tube of silica or other non-catalytic material provided with a sheet-iron catalyst. The carbonyl accelerates the reaction and allows it to be conducted at a lower temperature, giving a more finely divided product. The tube has mechanical means for detaching the catalyst and conveying it in counter-current to the gas and for permitting removal of the carbon without admitting air. In a modificatiod, the carbon monoxide is passed directly into the hot zone and iron carbonyl is also added by passing a small proportion of the gas over reduced iron at atmospheric or higher pressure, or by bubbling it through iron carbonyl, or by injecting the carbonyl directly into the zone. Other carbonyls may also be used. By water cooling the inlet pipe, decomposition of the car- 'bonyl before it reaches the catalytic zone is prevented. The carbon may be retained in continuous agitation in the hot zone for about 12 hours to reduce its iron content. The carbon monoxide may contain an indifferent gas. The first Provisional Specification describes the use of carbon monoxide containing nitrogen, and, in that form of the process in which two temperature zones are employed, the removal of iron from the gas from the first zone by heating &c. The gas may be expanded to atmospheric pressure and mixed with further carbon monoxide before or after the removal of the iron.

Title: Improvements in connection with submersible burners
IPC: F23D14/44
Filed: 1944-09-18
Abstract: 585,893. Subaqueous burners. SWINDIN, N. Sept. 18, 1944, Nos. 17813/44 and 22735/45. [Class 75 (i)] [Also in Group XXIX] The flame orifice of a submerged flame burner is cleansed by a pricking device operated periodically or when the flame orifice becomes obstructed. In Fig. 1, clogging of the gas burner 1 by salts precipitated from acid or other liquid being concentrated in a container equalizes the gas pressures on opposite sides of an orifice plate 5 in the burner supply conduit 4 and thereby closes a static mercury switch 6, in the circuit of a solenoid 13. The solenoid 13 closes the circuit to a solenoid 14, the core 15 of which raises a valve 19 to admit compressed air below a piston 23 and cause a pricker 29 carried by the piston rod 25 to enter the burner orifice. At the top of its stroke a trip arm 31 on the piston rod operates a pivoted time delay mercury switch 33 to break the circuit of the solenoid 13 and the valve 19 falls to admit air above the piston 23 and return the pricker to its initial position. The operation is then repeated until the burner is clear of obstruction. The piston rod 25 is of rectangular section to engage a guide 26 and enters the container through a nut 40 and sealing bellows 30. The lower part of the piston rod may be articulated at 41 to the upper part and be given a slight twist adjacent the nut 40 to cause the pricker to be withdrawn from the flame path of the burner in its lowest position. In a modified arrangement the solenoid 14 directly operates the pricker. In another construction the solenoid 13 closes the circuit to an electric motor driving a centrifugal pump to supply fluid to a piston operating the pricker. In a further construction the pricker is operated by an electric motor a predetermined number of times at intervals determined by a rotary contact disc driven by a single phase synchronous electric motor. The pricker may consist of a spindle 74 carrying a head consisting of a centre-seeking coned top 70 and radial arms 72. The arms 72 are ploughshaped on one side so as to cause the spindle to rotate in its support 71 and cut vertical grooves in the incrustation during their upward movement. The other side of the arms are formed with shear cutters which cut vertical grooves in the incrustation during their downward movement.
