Title: Production of hydrogen
Inventor: EASTMAN DUBOIS
IPC: C01B3/36
Filed: 1957-05-20
Abstract: A hydrocarbon, e.g. fuel oil or natural gas, is reacted with oxygen at elevated pressure, preferably 200-600 p.s.i.g. and a temperature above 2000 DEG  F., preferably above 2250 DEG  F., so as to produce a mixture of hydrogen and carbon monoxide, the mixture is cooled by contact with liquid water to a temperature of 350-600 DEG  F., preferably 400-500 DEG  F., in a period of not more than 0.2 sec., at least a portion of the water thereby being vaporized, and the carbon monoxide in the resulting mixture is reacted with steam to produce carbon dioxide and further hydrogen.  Contact may be effected by injecting the water into the gas or vice versa. 0.5-1.0 volume of steam per volume of mixture of hydrogen and carbon monoxide may be <PICT:0837030/III/1> produced.  The hydrocarbon may be reacted with a gas containing more than 95% of oxygen obtained by rectifying air. The oxygen-containing gas may be compressed to a pressure of 100-1500 p.s.i.g. before oxidation.  Ammonia may be produced from the hydrogen product by reacting with gas containing more than 99% of nitrogen also obtained by rectifying air.  As shown, air is rectified in a plant 6 at 80 p.s.i.g. to yield 95% oxygen and 99.7% nitrogen.  The oxygen is passed at a rate of 180 tons per day via a compressor 7 into a synthesis gas generator 8, at a temperature of 300 DEG  F. and a pressure of 340 p.s.i.g., where it burns a surrounding stream of natural gas at a temperature of 915 DEG  F. passed at a rate of 5,583,000 cu. ft. per day from a preheater 9 to produce a gas containing ca. 32% of carbon monoxide.  The generator is operated at a pressure of 340 p.s.i.g. and a reaction temperature of 2600 DEG  F. The residence time, cased on the synthesis gas product, is 3.5 sec. The synthesis gas is passed into a water jacketed transfer line 11, wherein it is contacted with sufficient quench water from line 13 to reduce the temperature of the gas to 450 DEG  F. with the production of 0.75 vol. of vaporized water per vol. of mixture of hydrogen and carbon monoxide.  The cooled gas passes to a saturator scrubber 12 containing bubble-cap trays or packing, wherein it is scrubbed with water recirculated via pump 16.  An aqueous carbon dispersion passes out via line 15 while the scrubbed gas is reheated to 650 DEG  F. (heater not shown) and passed to a shift converter 17 containing an iron catalyst.  The gas from the shift converter, which contains ca. 2% of carbon monoxide and is at a temperature of 750 DEG  F., is cooled to 100 DEG  F. with condensation of water (cooler not shown) and is contacted with aqueous monoethanolamine solution optionally followed first by aqueous sodium hydroxide solution and then by liquid nitrogen in a purification unit 18. The resulting hydrogen is passed to an ammonia synthesis unit 19 wherein it is reacted with nitrogen passed from the rectification plant 6 via line 21.

Title: Hydraulic valve assembly for power transmission systems
IPC: B60T13/14
Filed: 1946-05-27
Abstract: 651,963. Fluid pressure control of brakes. BENDIX AVIATION CORPORATION. May 27, 1946, No. 16084. Convention date, June 22, 1945. [Class 103 (i)] [Also in Group XXIX] A hydraulic valve assembly, applicable to braking systems, comprising supply, exhaust and delivery ports controlled by valve means and a piston, movable with the valve control member, subject to the reaction of the pressure in the delivery port to provide a force opposing movement of the control member, is characterised by means responsive to the rate of fluid flow to the delivery port for partially neutralizing the opposing force. Rotation of the lever 38, Fig. 2, moves the reaction piston 30 connected to the hollow stem 29 so that the stem end seats on the head 25 and closes the delivery line 41, Fig. 1, from the exhaust 40 via passages 42, 45, and lifts the spring-loaded poppet 22 to allow pressure fluid to pass via passages 21, 55, 57 to the delivery line. A venturi 49 fitted in the delivery port has throat passages 51 leading via passage 47 to the piston chamber 31, so that when fluid flows the pressure reduction at the throat, equal to the pressure drop from the beginning to the end of the delivery line, is communicated to the reaction piston. In the modification, movement of the lever 74, Fig. 3, moves the reaction piston 82 to close the exhaust port 63 and allow fluid to flow from the inlet 61 through the venturi 71 and passages 72, 65, to the delivery port 62, the throat of the venturi communicating via passages 67, 66 to the end 64 of the reaction piston. In another, arrangement, rotation of the lever 107, Fig. 4, moves the differential reaction piston 99 to close the passage 97 by which the delivery passage 92 communicates with the exhaust 93, and then open the spring-loaded poppet 94 to allow pressure fluid to pass from the inlet 91 through the restriction 103 to the delivery. The pressure drop across the restriction is applied across the differential reaction piston by the passage 105 leading to the smaller piston face 106.

Abstract: 816,874. Respiratory appliances. NORMALAIR Ltd., and MINISTER OF FUEL & POWER. April 26, 1956 [June 6, 1955], No. 16181/55. Class 81 (2). A closed-circuit breathing apparatus, primarily for use in mine rescue work, and including a liquid-oxygen cartridge in a vacuum-jacketed container in Fig. 1, is provided with inspiration and exhalation valves disposed upstream and downstream respectively of the mouthpiece and a vent valve for excess gas located between the exhalation valve and the CO 2  absorber. The oxygen cartridge a is carried in a vacuum-jacket b and at least part of the exhaled air passes around the cartridge to assist evaporation. To prevent the temperature of the circulating, gas from falling too low, part may by-pass the cartridge container, if desired, under the control of a manually-actuated flap valve. In another arrangement, a perforated plate is fitted over the inlet to the cartridge container and in this case, moisture in the gas is deposited as snow on the plate so that the gas is forced to flow entirely through the by-pass but when the temperature of the gas reaches a sufficiently high value, the snow melts and the gas again passes through the container. In yet another arrangement the perforated plate is disposed in the inlet pipe to the cartridge container, and the flow through the by-pass is additionally controlled by a manually-actuated butterfly-valve.

[Class 38 (iv)] Power is transmitted from an engine shaft 2 to a load shaft 5, 6 through a self-excited dynamo-electric machine G the armature 4 of which is mounted on the shaft 2 and its field system 3 mounted on the load shaft on which is also arranged the rotor 8 of an electric motor M having a stationary field system. A clutch 9 is arranged to couple drive and load shafts when starting up has been effected and a common regulator R is arranged to control the excitation of both machines during running up and to short circuit the machines and energize the clutch 9 when running up has been effected. The engine 1 is started by the generator G being driven from a battery B when the regulator R is in the position a, a switch T in the position a<1> and a press switch S is operated. Release of the button S and operation of the switch T to the position b<1> with the regulator R in the position b connects the generator G in series with its field which is bridged by the whole of the diverter resistance h across the motor M through a reversing switch u. As the arm 13 of the regulator is moved towards its middle position c the resistance h is cut out and the generator excitation and motor speed increase. Further movement of the arm 13 connects the whole of resistance h across the motor field 7 and progressively reduces its excitation until finally, in the position d, the motor and its field are bridged by resistances rl, r2 and h and the drive is through the generator and its field. In the final position f an electromagnetic clutch 9 is energized to give direct drive between the shafts 2 and 5 and the generator and motor are short circuited. Reverse drive is not provided for except for short periods when the motor drive is used.

Preserving meat, eggs, fruit, &c.-Foodstuffs, such as meat, eggs, and fruit, are preserved by keeping at a low temperature in an atmosphere of common salt which may be produced by atomization of a salt solution. The pieces of meat &c. are wrapped in a gas-permeable covering which does not absorb moisture, e.g. a textile-fabric impregnated with paraffin, and placed with a clear space around each in an insulated chamber 11 having doors 12. The chamber is then cooled to a temperature above the freezing point and a salt fog next produced from a salt solution supplied from tank 1 and tubes 2, 15 to atomizers 3 supplied through pipes 7 with compressed air from a pump 6. The air is passed through a cooling coil 8 in a tank 9 and the condensed water is withdrawn through a trap 10. The fog may contain between “-1 per cent or more of salt and is constantly agitated by fans 14 except during renewal. When fresh fog is being introduced, which may be every eight hours in the case of meat, the used fog and the gases from the meat &c. in the chamber are expelled through doors or automatic valves located at the bottom of the chamber and designed to prevent the pressure rising above atmospheric. The humidity is not more than is sufficient to carry the required percentage of salt. Refrigerating means are provided in or connected with the chamber which is sterilized and dried before use.

A magnetically soft sintered body is made by forming a mixture of magnetically soft metal or alloy powder and Ni-Zn, Mu-Zn, or other highresistance ferrite, the mixture containing 1-20 per cent of the ferrite, compressing at 6 to 8 tons/sq. cm., sintering in a vacuum or inert atmosphere, at between 900‹ and 1100‹ C., and thereafter compressing at 600‹ to 700‹ C. or compressing while cold and again sintering at 900‹-1200‹ C. This reduces the pore volume to less than 10 per cent, preferably less than 5 per cent of the volume of the body. To coat the particles which are flattened, the ferrite is finely divided and mixed with the metal particles while wet. The alloy powder should have high resistivity compared with iron, and may comprise an iron silicon alloy to which is added 30 per cent of a readily compressible iron powder.
