Title: Improvements in or relating to the feed water control of forced feed tubulous steam generators
IPC: F22B35/06
Filed: 1934-04-03
Abstract: 436,086. Instantaneous steam boilers. DEHN, F. B., 103, Kingsway, London.-(Doble Steam Motors, Ltd.; 4053, Harlan Street, Emeryville, California, U.S.A.) April 3, 1934, No. 10070. [Class 123 (ii)] Two thermostats are arranged in a forced feed tubulous steam boiler 7 and operate so that when the water supply in the main portion of the boiler becomes deficient a secondary supply 73 is cut off by the one thermostat 74 and the increasing temperature causes the other 32 to shut down the fuel supply comprising a blower 23 and carburetter 27. A rocker 36 operated by thermostat 32 to make and break the blower circuit at contacts 43, 44, also affects contacts 59, 61, in a circuit including the solenoid of a valve 71 in the secondary feed supply in such a way as to introduce this supply when the temperature near thermostat 32 is a few degrees below that at which the blower is interrupted. Usually this supply forestalls the separation of the blower circuit contacts and the heat supply is continuous. To protect the main portion of the tubing from excessive heat owing to a deficiency of water through inlet 17 thermostat 74 is caused, when such temperature is reached, to separate contacts 64, 66, in the circuit of the secondary feed valve. Thermostat 32 not then being cooled by this feedwater causes the blower circuit to open. Specification 436,087 is referred to.

Title: Improvements relating to the rolling of metal wires and rods
IPC: B21B35/02
Filed: 1952-04-24
Abstract: 714,737. Rolling. PROPERZI, I. April 24, 1952 [Feb. 19, 1952], No. 10372/52. Class 83 (4). The passes 22 ... 34, Fig. 7, of a continuous roll train for the manufacture of metal rod or wire, each comprising three rolls 18, 19, 20, Fig. 3, spaced 120 degrees apart, are closely spaced with their drive shafts rotated in opposite directions and arranged alternately above and below the line of rolling, the rolls, in alternate passes, being shaped to produce threesided and round or hexagonal cross-sectional shapes on the work. In Fig. 3, the drive shaft 17 of the pass is arranged above the line of rolling to carry the upper roll 18 and two bevel gears 99, 100 which rotate bevel gears secured to the lower rolls 19, 20. These lower rolls are adjustable radially with respect to the line of rolling by means of screws 95 ... 98, Fig. 5, which act on bolts 94 mounted in the bearing housings 91 for the rolls. A tube 106 in screw-threaded engagement with a pin 108 and fitted with a squared end 107 for rotation by a key enables the pass to be withdrawn from the line of rolling. In the preferred embodiment, the passes are arranged in two groups 22 ... 28 and 29 ... 34, Fig. 7, each of which is driven by a train of toothed gearing from a main shaft 39 and 45. Each drive shaft is connected with its driving gear in the train by a splined connection while the driving gears are rotatably connected by intermediate gears which produce a reversal of rotation between each pass and a progressive increase in speed from pass to pass in the direction of rolling.

Patent GB-445319-A (GB)
Title: Improvements in recovery of carbon dioxide from waste gases
IPC: C01B32/50
Filed: 1935-04-03
Abstract: <PICT:0445319/III/1> Carbon dioxide is recovered from gaseous mixtures containing it but substantially free from sulphur compounds by absorbing from the gaseous mixture a portion of the carbon dioxide by reacting it with a solution of an alkali metal carbonate to form bicarbonate, absorbing from the gaseous mixture another portion of the carbon dioxide by reacting it with ammonia in the presence of water with the formation of an ammonium salt of carbonic acid, and subsequently recovering the carbon dioxide from the alkali metal bicarbonate and the ammonium salt.  The gases may be passed through an alkali metal carbonate solution mixed with an ammonia solution; or the gases may be passed through an alkali metal carbonate solution and then through an ammonia solution or a solution containing both alkali carbonate and ammonia.  Cooled flue gases which have been scrubbed free from dust and sulphur compounds are forced by a fan 11 into the base of a tower 13 up which they pass in counter-current to potassium carbonate solution having a temperature of 20--25 DEG  C., introduced through a pipe 19. The lean gases are delivered by a pipe 14 to the bottom of a tower 15 up which they pass in countercurrent to potassium carbonate solution, heated to 40--60 DEG  C., introduced through a spray 23, aqueous ammonia introduced through a spray 25 and cold water introduced through a spray 28, the gases finally passing away through a stack 26.  The ammonia from the spray 25 absorbs the carbon dioxide which has escaped absorption by the potassium carbonate, the resulting solution of ammonium salts passing down the tower 15 and mixing with the potassium carbonate solution to form potassium bicarbonate with the liberation of the ammonia which is carried up the tower by the gases.  The ammonia is prevented from escaping from the tower by the water spray 28.  The ammonia is thus used cylically in the tower and it is only necessary to add sufficient ammonia by the spray 25 to replace operating loses.  The partially carbonated solution is withdrawn from the tower 15 through a pipe 16 and is pumped through a cooler 18 to the top of the tower 13.  The solution of potassium bicarbonate withdrawn from the tower 13 passes to a lye boiler 21 where the carbon dioxide is liberated and the carbonate regenerated for return to the spray 23.  The carbon dioxide is dried by compression, any condensate containing ammonia being returned to the spray 25.  The towers 13 and 15 are preferably filled with Raschig rings.  If desired, the carbonate solution may be passed first through the tower 13 and then through the tower 15 or the tower 13 may be omitted.  Sodium carbonate may be used instead of potassium carbonate.
