Title: Improvements in or relating to automatic control systems
Inventor: ROBINSON KENNETH ARTHUR
IPC: D06B11/00
Filed: 1958-08-22
Abstract: 901,685. Automatic speed control systems. LANCASHIRE DYNAMO ELECTRONIC PRODUCTS Ltd. Sept. 21, 1959 [Aug. 22, 1958], No. 27074/58. Class 38 (4). In an automatic control system, a moving element of an electro-mechanical transducer, responsive to a current to be controlled, is coupled to a detector which over a restricted range detects movement of the element and a restoring force is applied to the moving element so that the desired value to which the current can be controlled is variable over a greater range than that represented by the response of the detector. As shown, an armature of a motor 15 is supplied from a Ward-Leonard generator 14, the field of which is controlled so as to maintain the speed of the motor constant. The output of a tacho-generator 16 coupled to the motor 15 energizes a moving-coil 1 rotatable in a field due to a permanent magnet 3 against the action of a spring 4. A pointer 6 mounted on the moving coil and movable between stops 7, 8 carries a plate 11 forming a variable capacitor with a plate 10. Variation in the capacity between the plates when the current through the coil causes the pointer to move away from stop 7 causes a control unit 12 to vary the energization of the generator field so as to vary the supply to the motor 15 and tend to maintain the speed constant. The spring 4 is connected to an arm 5 movable over a scale 20 to set the spring torque representative of the desired speed. The capacity detector may be replaced by an inductive, a photo-electric, a potentiometric, or a contact-making device.

Title: Improvements in and relating to zeolites
IPC: C01B39/02
Filed: 1958-08-25
Abstract: A synthetic zeolitic molecular sieve, designated zeolite D, of general formula <FORM:0868846/III/1> , where w is 4.5 to 4.9, x is from 0 to 1 and y is up to 7, is prepared by forming an aqueous sodium - potassium aluminosilicate mixture having an initial composition in terms of oxide mol-ratios (Na2O+K2O)/SiO2 from 0.45 to 0.65, SiO2/Al2O3 of 28 and H2O/(Na2O+K2O) of 18 to 45, and maintaining the mixture at 25 to 150 DEG C. until the crystalline zeolite forms. Isomorphs may be prepared by cation exchanging the zeolite with solutions containing sodium, potassium, calcium, magnesium, zinc, strontium or lithium ions.  The initial mixture may be formed from sodium aluminate, alkali, sodium silicate and aqueous colloidal silica sol.  Characteristic X-ray diffraction patterns for the zeolite are given.  The zeolites may be employed as absorbents by dehydration in vacuo at about 350 DEG C.  Oxygen, nitrogen and argon are absorbed at -196 DEG C. and water, propane and n-pentane are absorbed at 25 DEG C.  The calcium exchanged zeolite D may be employed to separate mixtures of isobutane, which is not absorbed, from mixtures thereof with propane, butane, or pentane or in drying hydrocarbons such as isobutane or benzene.  Similarly normal paraffins may be separated from mixtures with branch-chained, aromatic or cyclic hydrocarbons; normal hydrocarbons are selectively absorbed.  The zeolite may also be employed to dry gases or as a desiccant.  Desorption may be effected by washing with water or steam or purging at elevated temperature.  The zeolite may be pelleted if desired in a mixture with clay. Specific zeolites referred to are 0.47Na2O:0.53K2O:Al2O3:4.65SiO2: 6.6H2O, 0.46Na2O:0.60K2O:Al2O3:4.90SiO2:6.7 H2O and 0.92CaO:0.08K2O:Al2O3:4.65SiO2: 7H2O.

Title: Process for the regeneration of a sulphur dioxide acceptor comprising carbon
IPC: C01B31/08
Filed: 1964-07-01
Abstract: A sulphur dioxide acceptor comprising carbon, which has been used for the removal of sulphur dioxide from flue gases, is regenerated (with the formation of SO2 and/or H2S) with a reducing gas or gas mixture at a temperature of from 250 DEG  to 700 DEG  C., and preferably of from 300 DEG  to 500 DEG  C.  The acceptor consists of products containing free carbon, for example charcoal, animal charcoal, various activated carbons, peat charcoal, lignite charcoal and coke. The regeneration is preferably carried out in the presence of steam, in particular the reducing gas mixture containing from 3 to 10% by weight of steam. The reducing gas or gas mixture is preferably a hydrocarbon or a gas mixture containing a hydrocarbon, in particular methane or a gas mixture containing methane, for example natural gas. Preferably, the acceptor is heated and simultaneously regenerated with a gas mixture obtained by oxidation of a reducing gas with less air than that required for complete combustion.  The acceptor may be continuously withdrawn from the sulphur dioxide accepting zone, in which zone the gas or gas mixture is preferably preheated, and continuously regenerated, the regenerated acceptor being continuously recycled to the accepting zone.  The acceptor may have been used for the removal of sulphur trioxide, in addition to sulphur dioxide, from the flue gases.
