Title: Process and apparatus for purifying low-boiling gases for gas mixtures
Inventor: BALDUS WOFGANG
IPC: F25J5/00
Filed: 1965-06-08
Abstract: 1,105,925. Adsorption process for purifying gases LINDE A.G. 8 June, 1965 [5 June, 1964], No. 24127/65. Heading B1L. Compressed crude gas or gas mixtures boiling below 50K such as H 2 , He. or Ne, are freed from the 'bulk of the low boiling impurities present therein in a first adsorption stage comprising at least two adsorbers which can be switched between adsorption, regeneration, and recooling phases in succession, and are then freed from the remaining low boiling impurities at a lower temperature in a second adsorption stage having at least one adsorber. Incoming raw H 2  from compressor 1 is freed from CO 2  and H 2 O by adsorbers 3 and 5 and cooled to below 100K by heat exchangers 2, 4, and 6, and then to 90K by bath 8 of liquid N 2 . Liquid CH 4  condenses and is collected at 9, while the crude H 2  containing e.g. 2% CO, CH 4  and N 2  is now fed to the first-stage adsorbers of which 10 is in the adsorption, 12 in the regeneration and 11 in the recooling phase. The gas leaving adsorber 10 is recooled in the N 2  bath 8, some of the effluent gas in duct 14 being used to recool adsorber 11 before it rejoins the main stream to the next stage. Heat exchanger 17 cools the gas stream containing, for example, 100 ppm of impurities, to 35-45K before it enters one of adsorbers 20, 21. The effluent H 2  contains 0.5 ppm of impurities. The adsorbent in all the adsorbers may be silica gel or a molecular sieve. Adsorber 12 is incompletely regenerated at 180-220K. for re-use by means of a scavenging gas; reduced pressure may also be used in regeneration. Incomplete regeneration is preferred to complete because less recooling, is thereby needed.

Title: Improvements relating to the removal of iron from materials containing the same

Filed: 1925-10-03
Abstract: 256,428. Johnson, J. Y., (Badische Anilin & Soda Fabrik). Oct. 3, 1925. Carbonyl processes.-Iron is removed from materials, such as ores, containing the same by acting on tEe said materials with a rapid current of carbon monoxide, or a gas containing carbon monoxide, of sufficient speed to carry away all the iron carbonyl formed at an elevated temperature and pressure. The ores may be subjected to reduction until substantially all the iron is in the metallic form before treatment with the carbon monoxide &c. and the iron recovered from the carbonyl by exposing the latter to a high temperature. In an example, ground titaniferous iron sand containing about 25.2 per cent of iron is first reduced by a current of dry hydrogen at ordinary pressure and at 900‹ C. The reduced mass is then subjected to the action of carbon monoxide at a pressure of 200 atmospheres and at 200‹ C. and the iron carbonyl produced is condensed in a suitable receiver.

Abstract: 1438972 Composite, bulky yarns TEIJIN Ltd 24 May 1973 25008/73 Headings D1F and D1W A composite, bulky yarn is produced by feeding a sheath yarn B to a core yarn A, which is being false-twisted by means of a false-twisting spindle, passing the yarns through a heater to heat set the yarns and then through the spindle in such a manner that yarn B becomes wrapped around yarn A prior to the heat setting, the process being carried out under conditions such that and where Tn is the number of turns per metre exerted by the false twisting spindle, DA and DB are the deniers of the yarns, and R is the overfeed ratio of the sheath yarn B. The ratio R is defined as where 11, 12 are the velocities of the core and sheath yarns. The position of the point at which yarn B contacts yarn A is maintained constant by means of a thread guide located along the core yarn at a point between the means for feeding the core yarn to the spindle and the point at which yarn B would contact yarn A if the guide were removed. Typical composite yarns are shown in Figs. 2(E) and 2(F). The composite yarn may be napped by passing the yarn over a rotating napper roller having a rough surface. The roller may be located between the heater and the spindle. Two of the composite yarns so produced may be formed into a composite yarn by bringing them together on the surface of a napper roller. Sheath yarn B may comprise two or more different yarns.
