Title: Improvements in vacuum feed devices
IPC: F02B1/00
Filed: 1919-01-08
Abstract: 139,251. Muzzy, W. H. Jan. 8, 1919. Vacuum apparatus.-A fuel-feed system for internal-combustion engines comprises a vacuum chamber 2 connected by a pipe 9 to the source of suction and by a pipe to a low-level tank, a chamber 13 from which the fuel passes by gravity to the outlet, and a siphon 27 which automatically controls the pressure in the vacuum chamber. Air is admitted to the outer vessel 1 through a pipe 32 and cock 32a, the pipe passing round the exhaust pipe 36 and having its inlet, if desired, in the radiator cap 37, so that the air may be moist and heated. When this air reaches the vacuum chamber through a tube 21, the fuel in the chamber discharges through pipes 19, 16, provided with non-return valves, into the vessel 1 and the delivery chamber 13. As soon as the fuel level in the vessel 1 reaches the top of the tube 24 forming part of the siphon, this tube is filled, sealing the lower end of the tube 21, so that a partial vacuum is again formed in the chamber 2. The fuel is then drawn up the tube 21 by the vacuum in the chamber 2 until the level in the vessel 1 falls below the bottom of the siphon. Air is then drawn into the vacuum chamber again, and fuel is discharged as before. The siphon en. sures that a certain quantity of fuel must be drawn up through the tube 21 before the vacuum is destroyed. The aperture at the top of the tube 21 is restricted by a ball 33 which cannot quite close the aperture. Flooding of the vacuum chamber is prevented by a float 40 and valve 8. The cock 32a is closed at starting to enable a vacuum to be formed, and it may afterwards be turned so as to admit air direct to the vessel through a by. pass 32<b>. Reference has been directed by the Comptroller to Specification 123,500.

Abstract: 649,898. Gas separation. ELLIOTT CO. Jan. 8, 1948, No. 619. Convention date, Feb. 21, 1947. [Class 8(ii)] In a gas mixture separation process at low pressure comprising cooling the mixture, e.g. air, by indirect heat exchange at exchangers 8 or 9 alternately with a portion of effluent gas, e.g. nitrogen, in a duct 14 of a rectification column 13, at least some of the resulting warmed nitrogen leaving 8 or 9 is compressed at 19, 21, cooled at 23, 26 by indirect heat exchange with another portion of 16 effluent nitrogen, and a part of the cooled compressed nitrogen is condensed, e.g. in a reboiler 28, for use as liquid reflux at the top of the column 13, and the remainder of the cooled compressed nitrogen is expanded at 32, 32a with performance of external work and is then used to augment at a duct 15 the cooling capacity of the effluent nitrogen, and in particular of the second portion thereof. In operation filtered air from a blower 2 traverses an after cooler 3, a refrigerator 4, silica gel driers 6 and the exchangers 8 or 9 according to which drier is being derimed as described in Specification 642,587, and a residual acetylene trap and cold accumulator 11 and passes to the column 13. Flow of that portion of compressed and cooled nitrogen to be expanded by turbines 32, 32a and cooled at 23 by nitrogen from the duct 15 is automatically controlled by a valve 25 under the influence of a float 48 responsive to the level of liquid oxygen in the boiler 28. Similarly the flow of liquid reflux is controlled by an automatic expansion valve 31, controlled by a float 49 Carbon-dioxide contaminated gaseous nitrogen is delivered through a duct 38 and a valve 44, and pure liquid oxygen is delivered through a duct 42 and an automatic valve 47 controlled by a temperature responsive element 50. In a modification the portion of the compressed nitrogen being fed to the reboiler is cooled by a portion of the effluent nitrogen passing along path 14 to exchangers 8, 9 and the portion of compressed nitrogen to be expanded at 32, 32a is cooled by effluent nitrogen traversing the path 15. In a further modification for yielding, gaseous instead of liquid oxygen, liquid oxygen withdrawn from the base of the column 13 is vaporized and cools a portion of the nitrogen leaving the compressors 19, 21 and if pure nitrogen instead of oxygen is required, the exchangers 8, 9 are cleared of oxygen instead of nitrogen effluent. In a still further modification all the nitrogen from compressor 21 is fed to the reboiler 28, and partially compressed, nitrogen is cooled by nitrogen and oxygen effluent in parallel exchangers before expansion at 32.
