Title: Control arrangement for a damper
IPC: F16K31/122
Filed: 1975-01-24
Abstract: 1474311 Controlling flow through filter AMERICAN AIR FILTER CO INC 24 Jan 1975 [18 March 1974] 3250/75 Heading B1T [Also in Division F2] A damper controlling the starting and stopping of flow through cloth fabric filter bags and preventing damage thereto has a valve blade 2 moved relative an opening 86 by a fluid ram 4 which is energised by a valve 6. The valve 6 is moved from a central closed position by solenoids 12, 14 which move the valve to opposite end positions in which one of the lines 8, 10 feeding the ram is connected to a pressure supply line 40 while the other line 8, 10 is connected to a restricted exhaust line 36, 38. Solenoid 14, which energises the ram 4 to close the damper, is energised by closing contacts 54 while the solenoid 16, which acts to open the damper, is energised by closing contacts 52. When contacts 52 are closed the solenoid 12 is energised through normally closed contacts 56. However when the damper blade has moved to partially open position an arm 80 closes contacts 68 to energise solenoid 66 to open contacts 56 to stop movement of the damper blade and to close contacts 72 to energise a timing element 73 which times out closing contacts 75. Solenoid 76 is thus energised to close contacts 70, reenergise the solenoid 66, close contacts 56, re-energise solenoid 12, and recommence the opening of the damper. A cylindrical projection 90 on the damper blade provides a constant flow through opening during initial movement of the damper. The ram 4 may be replaced by a motorised drive and gearing and the valve 6 by a suitable reversible drive.

Title: Improvements in or relating to the purification of hydrogen-containing gas mixtures
Inventor: FABRY GEORGE LOUIS
IPC: C10K1/16
Filed: 1963-01-26
Abstract: <PICT:1013422/C1/1> In a process for removing higher boiling point impurities from a hydrogen-containing gas mixture by washing the gas mixture with liquid N2 under pressure in a rectification column to produce a substantially pure H2-N2 mixture and residual washing liquid containing higher boiling point impurities, at least a part of the liquid N2 used as washing liquid on the column is produced by compressing gaseous N2, cooling the compressed N2 at least in part by heat exchange with at least a part of the substantially pure H2-N2 mixture and/or at least a part of the residual washing liquid, expanding at least a part of the cooled compressed N2 with the performance of external work to a pressure substantially below the pressure in the rectification column, liquefying the expanded N2, and pumping the liquid N2 so formed to the column pressure before feeding it to the column to serve as washing liquid. Feed gas, containing, say, CO, N2, A and CH4 as impurities, is compressed, passed through heat exchanger 1, where it is cooled partly by a portion of the pure H2-N2 product and partly by vaporized residual washing liquid, and further cooled in exchanger 2 with H2-N2 product.  The feed gas is then fed to rectification column 3 where it is washed by a descending liquid N2 stream.  The purified gas leaving the top of 3 is divided into two parts, the major passing through exchangers 2 and 1 and the minor part being used to cool unexpanded gaseous N2 in pre-cooler 5, the N2 being previously compressed in compressor 4.  The N2 is further cooled in conventional refrigeration system 6, whence one stream passes through expansion engine 10 to 8 where it is completely liquefied by heat exchange with residual washing liquor, from the sump of 3, which has already been partially vaporized in heat exchanger 9 following passage through expansion valve 14.  The liquid N2 stream leaves cooler 6 and passes to 7 where it is cooled by heat exchange with the minor part of the H2-N2 product. From 7 the N2 passes to expansion valve 13, where it is partially liquefied during starting up and adjustment of the plant, and subsequently enters separator 12 from which the gaseous portion is conducted to join the H2-N2 product upstream of 7, while the liquid portion is combined with the liquid from the first N2 stream and the combined liquid is subcooled in exchanger 9 prior to entering column 3.  The major portion of the pure N2-H2 mixture leaves exchanger 1 and is joined by the minor portion leaving exchanger 5.  The main bulk of the N2 fed to compressor 4 may be withdrawn and fed to the H2-N2 product to increase its N2 content to 75%, if direct production of NH3 is subsequently desired.
