Title: Total desalting of water
IPC: B01J47/026
Filed: 1953-11-23
Abstract: A method of treating water by total de-salting comprises passing the water through two beds of ion-exchange material connected in series, each bed, before exhaustion, being adequate in size and natural properties to purify the water completely and, when the first bed of the series has become practically completely exhausted, disconnecting it for regeneration and at the same time or shortly afterwards connecting a fresh bed in series with an after the second bed of the original series, which latter bed then becomes the first bed of the new series.  Three beds may be connected in series, the second and third being operated according to the above-described system; the first bed of such a three-bed arrangement may be regenerated at any time when the second and third are in circuit.  The term "bed" includes an arrangement comprising a cation-exchange bed and a separate anion-exchange bed, and also a mixed bed.  Specification 553,233 is referred to.

Patent GB-994729-A (GB)
Title: Redox-resins and a process for their production
IPC: B01J47/015
Filed: 1963-08-19
Abstract: A cross-linked redox resin is produced by polymerizing a vinyl anthraquinone together with a copolymerizable compound containing a >C=CH2 group in the presence of a cross-linking monomer in dimethyl sulphoxide at 100-200 DEG  C.  The anthraquinone may be 2-vinyl anthraquinone or 1-vinyl anthraquinone. Comonomers mentioned are styrene, methyl styrene, ethyl styrene and chlorostyrenes. Cross-linking agents are preferably aromatic divinyl and polyvinyl compounds, e.g. divinyl benzene or trivinyl benzene.  Polymerization catalysts used are the organic peroxides. The polymerization may take place in the presence of an organic liquid, e.g. butyl acetate, which dissolves the monomers but not the formed copolymer.  In exchanging groups such as sulphonic acid, carboxylic acid or phosphonic acid groups can be introduced into the copolymers by known methods.  The resins show a very low redox potential.

Title: Improvements in the treatment of iron-silicon alloys
IPC: C21D1/78
Filed: 1934-11-21
Abstract: The magnetic properties of iron silicon alloys are improved by subjecting the alloys to substantial deformation, e.g. to the extent of at least 40 per cent, in the cold or at a relatively low temperature and then annealing for a period of hours, e.g. from 4-100 hours, at 1000-1300 DEG  C., in a protecting gas such as pure hydrogen.  The alloys usually contain 0,5-5,0 per cent of silicon but with higher silicon contents the deformation may be effected at an elevated temperature, e.g. 100 DEG  C.  Intermediate annealing, e.g. at 800 DEG  C. for 1/2 hour may be employed if the cold working takes place in steps.  When the alloys are used in strip or bar form for the manufacture of ring cores, the strips &c. after the deformation may be built into rings of the desired shape to prevent sticking, separated by thin layers of clay, lime, &c.  The rings so produced are then annealed.

Title: Directional coupler cascading for signal enhancement

Filed: 1975-08-13
Abstract: 1526784 Directional couplers INTERNATIONAL BUSINESS MACHINES CORP 13 Aug 1975 [23 Dec 1974] 33647/75 Heading H1W A directional coupler system comprises a cascade of stripline couplers in which the output terminal of a coupler is connected directly to the input terminal of the succeeding coupler and the backward terminal of the said coupler is connected to the forward terminal of the said succeeding coupler. In the coupler A, the "input" terminal is denoted 55, the "output" terminal 52, the "forward" terminal 62 and the "backward" terminal 64. The input terminal of the system is 55 and the system output terminal is 72, terminals 60, 62 being terminated in the characteristic impedance of the striplines. The couplers have equal delay times and the connections 53, 57, 65, 69 are assumed to have negligible delay. The input signal to coupler A at 55 produces a delayed output signal at 52 which provides the input signal to coupler B at 54. The same input signal produces a backward wave at 64 which after delay in coupler B appears at terminal 68. Thus a backward wave at 68 consists of the last-mentioned signal added to the backward-coupled signal caused by the input at 54, which two signals are in phase. Thus the arrangement causes addition of the backward-coupled signals of each of the couplers. The forward-coupled (parasitic) signals are relatively displaced from each other by the time delay of the couplers and do not add to form a signal of significant amplitude. The Specification discusses the behaviour of the system in response to a ramp function, a step function, a periodic square-wave function and a non-periodic square-wave function. Where the input is periodic, the length of the coupler is made equal to a quarter wavelength at the input frequency.
