Title: Data processing systems
Inventor: HUBER J

Filed: 1972-08-30
Abstract: 1391216 Redundant processing systems SIEMENS AG 30 Aug 1972 [28 Oct 1971] 40100/72 Heading G4A A data processing system includes a store formed of three redundant storage units and two or three redundant processing units, each storage and processing unit having a pair of terminals for connection to processing and storage units, the arrangement being such that each processing unit is connected to two storage units, no more than two of the processing units are connected to any one of the three storage units, and each of the storage units is connected to at least one of the processing units. The arrangement enables system units having only two terminals to be interconnected in triplicate or duplicate. As described the store is triplicated SE1, SE2, SE3, one processor set is triplicated VE1a, VE1b, VE1c, and another duplicated VE2a, VE2b. Each terminal pair may include a comparator to detect differences in data supplied by supposedly redundant units. The Specification gives in some detail the procedures followed when a comparator detects a difference. For example, if a fault occurs in a triplicated processor, say VE la, the comparators in stores SE1, and SE2 detect a difference whereas that in store SE3 does not. Processor VEla can thus be identified as faulty. If however, a fault occurs in a duplicated processor only one store comparator detects a difference so that the faulty processor can not be identified. The system may be used to control a telecommunications exchange.

Title: Process for the production of elemental sulphur from sulphur dioxide
IPC: C01B17/04
Filed: 1970-08-24
Abstract: 1318257 Sulphur; purification of waste gases SHELL INTERNATIONAL RESEARCH MAATSCHAPPIJ BV 24 Aug 1970 [26 Aug 1969] 40648/70 Heading C1A Sulphur is prepared from SO 2  by passing a portion of the SO 2  into a reactor in which a hydrocarbon is undergoing a catalytic conversion at elevated temperature and recovering, from the products, an H 2 S-containing gas which is combined with the unreacted SO 2  according to the conventional Claus reaction, the Claus reaction may be carried out at elevated temperature over an alumina catalyst, or in a liquid which promotes the reaction, such as, diethylene and triethylene glycols, dipropanolamines and sulpholane. The quantity of SO 2  added to the converter may be up to 10% of the hydrocarbon and may be in gaseous or liquid state. If the SO 2  is to be the sole source of H 2 S two-thirds (molar) of the SO 2  is converted to H 2 S; alternatively, is there is H 2 S available from other sources, e.g. when the impurities in the hydrocarbon undergoing conversion liberate H 2 S, then only sufficient SO 2  is converted to bring the molar ratio of H 2 S : SO 2  to 2 : 1. Suitable hydrocarbon conversion processes include catalytic cracking, e.g. using a synthetic SiO 2 /Al 2 O 3  catalyst, and reforming or cracking processes carried out under hydrogen pressure such as hydrodesulphurization, and hydrocracking. The SO 2  is conveniently obtained by preparing an SO 2 -rich gas stream from the SO 2  present in waste gases, for example by absorbing the SO 2  on a solid acceptor comprising a carrier on which a metal and/or a metal compound, e.g. copper and/or copper compounds, have been deposited and regenerating the acceptor with a reducing gas such as hydrogen or hydrocarbons to yield an SO 2 -rich gas.

In an automatic feed weigher, for proportioning by weight constituent materials of a mixture used for bituminous road surfaces, a pointer shaft of a weigher dial 2 is coupled to a wiper spindle of a potentiometer 4 connected to a D.C. source, whereby a voltage output from the potentiometer 4 is representative of the actual weight of material in a weigh hopper 1 and energizes a coil 8 of a polarized relay. A second coil 11 of the relay is energized from a potentiometer 7 which is pre-set to provide a voltage representative of the desired weight of material in the hopper 1. In operation, with the hopper 1 empty the voltages across the coils 8, 11 are unequal and an armature 9 maintains a switch 12 closed in the position shown, and a control device 10 effects discharge of a first constituent from a storage bin I. The feed therefrom continues until the voltages are nearly equal whereupon the armature 9 opens the switch 12 which stops the feed of the first constituent and initiates the feed of a second constituent from a storage bin II. The above sequence is repeated for second and third constituents successively using a similar pre-set potentiometer for each constituent in place of the potentiometer 7 to apply a voltage to the relay coil 11 in opposition to a total weight representative voltage from the potentiometer 4.

General system. Tobacco fleece from the ripping machine is first reduced by sieving using a sieve conveyer or gutter with a 3 mm mesh, which passes about 90% of the material. The remaining fleece is long-fibred tobacco and foreign bodies. This material is passed on high speed conveyer 2 first to a spiked roller, whose distance from the conveyer is adjustable and is rotated at a speed somewhat less than that of the belt. The angled spikes spear filter plugs and cigarette lengths, which are removed by comb 4 and via channel 5. Alternatively an inclined roller or spiked belt is used at this stage. Photoelectric system. This represents the final sorting stage. Fluorescent lamps 8 illuminate the pieces of paper which contrast strongly with the brown tobacco and black conveyer belt surface. The lamps are energized at a high frequency and the detector circuit contains a filter to cut out this frequency. Reflected light passes via lenses 9, filters 10 matched to the lamp spectral range, prisms 11 to photocells 12 having similar spectral response to the filter pass band. The chosen wavelength is one which is not strongly reflected by the tobacco, but is by the foreign bodies. Reflected intensities above a certain threshold cause one or more electromagnetically controlled flaps 14 to be raised and allow the foreign body to be sucked into common exhaust chute 15.
