Title: Improvements in or relating to the removal of sulphur from gases
IPC: C10K1/20
Filed: 1953-10-19
Abstract: 740,662. Purifying gas. GASTECHNIK GES. Oct. 19,1953 [Dec. 15, 1952], No. 28825/53. Addition to 683,432. Class 55 (2). In an improved method of operation of the towers or cleaners of the parent Specification, fresh pelleted material is supplied only to the last cleaner of a series which performs the final purification, the material discharged from this cleaner is fed, after regeneration, into a circulation of previously discharged material which comprises an extraction process for the removal of absorbed sulphur. After extraction and before the circulating material enters the cleaner next to the final cleaner, the completely exhausted material is removed and replaced by the material from the final cleaner. The material in this cleaner is less active than that in the final cleaner but the H 2 S concentration is higher so that the rate of combination with H 2 S is such that much sulphur is removed when the material is circulated rapidly through the cleaner in order to make the maximum use of the material. The rate of circulation in this rough cleaner is made several times, preferably seven times greater than that through the final cleaner, and the material discharged is regenerated with air, extracted, the exhausted material eliminated, and the remainder returned to the top of the rough cleaner. One seventh of the material circulating should be removed at each cycle. The rough cleaner may be preceeded by an additional rough cleaner through which material circulates at twice the rate of circulation in the rough cleaner. Half the discharge from the additional rough cleaner is returned directly to the top after regeneration, the other half is dispatched for extraction and elimination and is returned to the top of the rough cleaner. The discharge from the rough cleaner is passed to the top of the additional rough cleaner. When it is necessary to dilute the crude gas, e.g. in the case of an exceptionally high H 2 S concentration, the gas leaving the additional rough cleaner or the rough cleaner may be recirculated. The cleaner or cleaners may then be increased in size to accommodate the increased flow of gas.

Patent GB-391221-A (GB)
Title: Improvement in adsorber systems
IPC: F25B17/08
Filed: 1931-10-22
Abstract: <PICT:0391221/III/1> In an absorber system wherein activation heat is supplied by steam and subsequent cooling by means of a liquid such as water, the adsorbent, such as silica gel, is contained in tubes 15 in an outer casing 11, the tubes being exposed to the material to be treated in the space 18.  The space 21 is provided for the heating and cooling media.  The steam for activating is supplied from a boiler 25 preferably having a fluid fuel burner 26, the supply to which is controlled by pressure-actuated mechanism 29, arranged so that the steam pressure is maintained substantially constant.  The cooling water is supplied from a cooling tank 40, the circulation of water being maintained during the adsorption period by thermosiphon action, by an injector 50 or by a circulating pump. When the adsorption is complete, the valves 41<1>, 45 are closed, and steam admitted through pipe 33.  The water in the adsorber jacket is forced back into the cooler through a thermostatic steam trap 43, which prevents the entry of steam into the cooler.  The steam is condensed and its heat used to activate the adsorbent.  The condensate is delivered through the trap 43 to the cooler or returns to the boiler through the check-valve 35 and float feed apparatus 36.  When activation is complete, the steam is cut off, and cooling water admitted for a new adsorption phase. The cycle can be carried out continuously by suitable mechanical operation of the valves.  Two or more adsorbers may be used, one adsorbing while the other is being activated and cooled, this arrangement providing better load conditions for the boiler and cooler.  Either the boiler or cooler may be eliminated if a suitable source of steam or cooling water is available.

Title: Method of photography employing lenticular screens
IPC: G03B35/24
Filed: 1945-11-06
Abstract: 661,951. Multiple photographs; lenticular screen photography. RELIEPHOTOGRAPHIE SOC. POUR L'EXPLOITATION DES PROCEDES DE PHOTOGRAPHIE EN RELIEF M. BONNET. Nov. 6, 1945 [March 31, 1944; Aug. 10, 1944], Nos. 29577/45 and 29578/45. Drawings to Specification. Classes 98 (i) and 98 (ii). A method of photography employing a lenticular screen for recording on a single negative, by means of an objective of smaller aperture than the elements of the screen, a number of independent separate images and/or the subsequent printing of said separate images, is characterized in that the successive recording or subsequent printing of these different images is achieved by altering the angle at which light strikes the lenticular screen during recording or the angle at which it leaves the screen during printing. If spherically lenticulated screens are used, the screen and associated light-sensitive surface are caused to pivot about two perpendicular axes parallel to the axes of the screen. Instead of spherically lenticulated screens, two crossed cylindrical screens of equal thickness, but the upper one of twice the focal length of the other, are superposed in contact. As an alternative to pivoting the lenticular screen and sensitive surface, the objective may be displaced in perpendicular directions parallel to the face of the screen. Contact prints of particular images may be obtained in an analogous manner by placing the image-bearing layer of the negative, which is on the opposite side of the support to the lenticular screen, and the emulsion layer of the printing material in contact, and placing a light source behind an aperture of the same size and at the same distance from the negative as the objective employed in photographing the original. In the case of projection printing using the taking lens system, if the projected image is formed inconveniently near to or distant from the negative, the image plane may be changed by using as necessary a simple negative or positive auxiliary projection lens. Oblique marginal rays encountered due to the use of a very small aperture objective system may be suitably presented to the lenticular screen by placing a converging lens against the screen. Specification 283,954, [Class 98 (ii)], 615,530, 619,948 and 638,551 are referred to. The Specification as open to inspection under Sect. 91 states that instead of pivoting the screen and the sensitive surface, the successive recordings or printings may be produced by relative transverse sliding movements between the screen and the sensitive surface. This subject-matter does not appear in the Specification as accepted.
