Title: A process for removing ammonia and sulphuretted hydrogen from gases
IPC: C10K1/12
Filed: 1928-09-24
Abstract: 309,116. Hansen, C. J., (Assignee of Koppers Akt.-Ges., H.). April 5, 1928, [Convention date]. Drawings to Specification. Materials for purifying gas; purifier waste, revivefying.-Ammonia and hydrogen sulphide are removed from gases, e.g. coal distillation gases containing them in ratios less than 2:1 by scrubbing with a single liquor comprising iron or manganese thionate in solution and the hydroxide of the metal in suspension. So that the ratios of the iron in thionate form to that in the form of hydroxide may correspond to that between the hydrogen sulphide removable with ammonia to that in excess in the gas, the latter ratio, x :y, is determined by analytical test and the spent liquor is divided into two portions in the ratio 3x: 2y, these proportions of liquor required as thionate and hydroxide respectively being indicated by the equations of the scrubbing and regenerating reactions. The first portion is treated with sulphurous acid and the second is oxidized with air or other oxygen-containing gas, the two liquors then being returned to the scrubbing apparatus. Liquor to be worked up into ammonium sulphate and sulphur is freed from dissolved iron or manganese by treatment with the crude gas. Ammonia may be previously removed by cooling or cooling and washing with water in which case the iron-freeing operation may be effected by running the liquor through a scrubbing tower through which ammonia vapours obtained by distilling the condensate or ammonia wash liquor and containing hydrogen sulphida are passed. Ammonia from other sources may supplement that in the gas.

Title: Improvements in or relating to oil shale distillation
IPC: C10G1/02
Filed: 1952-10-31
Abstract: 706,164. Distilling oil shale. STANDARD OIL DEVELOPMENT CO. Oct. 31, 1952 [Oct. 31, 1951], No. 27450/52. Class 55 (1) In distilling oil shale maintained as a fluidized mass in a retort 15 by upwardly flowing oxygencontaining gases, part of the shale is crushed to a particle size of not less than half-inch in diameter and passed as a settled bed through a heat exchange zone 7 in countercurrent contact with distillation gases, and the other portion is ground to a fluidizable particle size not above quarter-inch and preheated by indirect contact with spent shale, as by circulating heat carrier pebbles first through a zone 75 in which they are heated by the spent shale and then through a zone 20 in which they pass downwardly through a fluidized bed of fresh shale. The coarser shale is heated by the distillation gases to e.g. 500‹- 1,000‹ F. and conveyed through a line 14 to an intermediate part of the retort. The remainder passes through a grinder 3 to the preheater 20 to which fluidizing gas such as product tail gas, flue gas or steam is admitted through a distributing core 27. The fluidized shale ascends the preheater in counterflow to the heat-carrying pebbles from zone 75 and leaves by a line 31 at 500‹- 900‹ F. for supply to an intermediate part of the retort. Air oxygen-enriched flue gas or steam mixed with flue gas and air or oxygen is blown into the base of the retort and in the embodiment shown heated by a part of the spent shale discharged through a pipe 63 and reintroduced through a pipe 69 after some heat has been extracted in a steam boiler 65. Sufficient heat is generated by combustion in retort 15 to maintain distillation at 800‹-1,200‹ F., the coarse and ground shale rapidly disintegrating to a particle size of 5-200 microns. High velocity gas jets 40, 42 may be used to assist the reduction. Gases and vapours may be scrubbed in a section of baffle cap plates 45 supplied with heavy oil, afterwards fed by downcomers 49 to the bed for cracking. After passing through heat exchanger 7 the distillation gases pass to a gas and liquid separator 55, if desired through a further cooler 53. Of the spent shale discharged from the retort, that part which is returned for heating the fluidizing gases passes through a line 73 to an intermediate part of the pebble heater 75 and the other part is fed to the bottom through a line 77. The shale is fluidized by hot steam, air, flue gas &c. and ascends in counterflow to the pebbles admitted at the top from a conveyer 28. Specification 584,386 is referred to.

Abstract: 319,614. Norddeutsche Diktograph-Ges. Sept. 24, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Selective signalling systems.- In an indicating system adapted to show the whereabouts of employees, indicators are provided at a central station and at each transmitter, means being provided so that at any transmitter the indicators relating to another transmitter may be operated. The Figure shows transmitters A, B and corresponding pairs of receivers, one at the transmitting station and the other A<1> at a central station. The operation of receiver A<1> from transmitter A is effected by a selector dial 4 which energizes a relay R2 and a switching device St2 so that the first train of impulses controls the " tens " indicator stepping magnet 1 and the following train the " units " magnet 2, while the cessation of the current impulses completes the circuit of the release magnet 12 of the device St2. The indication may be cancelled by key 13 which energizes release magnets 3. The operation of the receiver A<1> from transmitter B is effected by operating the switch 5 to close contacts 37, 38 when relay R1 and switching device St1 are operated by the impulse sender 4 and selector switch W is operated to select the wanted receiver A<1>. The indicator A<1> is then operated from transmitter B through relay R1 and switching device St1 which connects the line 57 successively to contacts connected to lines 53, 60 to operate the " tens '' and " units " indicators, and the final energizing of the magnet 9 of the switching device St1 effects the operation of the release magnets 8, 10 of the selector W and the device St1. In a modification, when the installation is large, instead of a common relay R2 for all signalling points separate relays may be employed.

Abstract: 677,148. Data-storing apparatus. BRITISH TABULATING MACHINE CO., Ltd., and KEEN, H. H. Oct. 25, 1950 [Nov. 1, 1949], No. 27954/49. Class 106 (i). An electro-mechanical data store, e.g. for use in a record card punching-machine as described in Specification 621,697, [Group VIII], comprises rotatable discs each bearing radially extending wires 7, Fig. 1, a wire-setting gate 15 for each disc, concentrically mounted arcuate insulating means 10 for retaining the set wires in position, and sensing means 9 which make electric contact with the set wires to complete read-out circuits. As shown, the wires 7 for each disc are clamped in rings 3 fixed to an insulating gear 1 which is rotatably mounted on a bushing 53 keyed to a shaft 11 and adjustably carrying the sensing brush 9; each readout circuit comprises shaft 11, bushing 53, brush 9, set wire, rings 3, a wire in contact with gate 15, contacts 58 and a terminal 59. The discs and brushes 9 are rotated together during data entry, and the brushes are rotated alone in the other direction during read-out by gearing connected by input and output half-revolution clutches 18, 19, Fig. 2, to a continuously-driven shaft 20, the differential 46, 37, 48 ensuring that if both clutches are operated the brushes are rotated at a rate corresponding to the difference between entry and read-out speeds. As each wire moves past its gate 15 it is guided, if set, to the unset position by the nose 55 and subsequently allowed to return under its own resilience through a slot 16 only if the gate is shifted upwards by a setting magnet 17, the set and unset wires being then retained on opposite sides of the insulating ring 10. Contactoperating cams 60, 61 on shaft 42 geared to shaft 11 prevent further operation of clutches 18, 19 respectively when the store is full (when an indicating lamp may be lit) and when the brushes are in the starting position just beyond the gates 15.
