Title: New crystalline sodium borate
IPC: C01B35/12
Filed: 1953-08-26
Abstract: <PICT:0737925/III/1> Sodium borate monohydrate is produced by heating a sodium borate or mixture of sodium borates having a molar ratio Na2O : B2O3 between 0.4 and 0.7 and a water content as hereinafter defined, in a closed vessel until equilibrium is attained or until a sufficient quantity of monohydrate crystals have deposited from solution, and to a working temperature which is dependent as hereinafter defined on the molar ratio and water content, filtering and washing the product. Fig. 1 is an isothermal diagram of the relevant part of the system Na2O-B2O3-H2O at 150 DEG C.: B represents pure sodium borate monohydrate, C a borate produced by Augers ("Augers sodium borate") and A the ternary point at which the solubility curves AD and AE of Augers sodium borate and the monohydrate, respectively, meet. The water content of the starting materials is so chosen that it lies within the area marked "1 : 2 : 1 + soln" on Fig. 1, or within the corresponding portions of similar isothermal diagrams. Below 115 DEG C., however, sodium diborate monohydrate is not formed. By adjusting the operating temperature and the water content, any ratio Na2O : B2O3 from 0.4-0.7 may be used. This ratio may be adjusted by adding sodium metaborate, boric acid, or caustic soda. Water in addition to that present in the crystalline material employed may be added. Preferred starting materials are mixtures of borax deca- or pentahydrate and crystalline sodium metaborate or caustic soda. The preferred process uses a molar ratio of 0.52, a total water content of 35 per cent by weight of the starting materials and a temperature of 170 DEG C. Other advantageous proportions and temperatures, and examples, are given.

Patent ES-301547-A1 (ES)
Title: Electromagnetic circuit breakers
IPC: H01H51/34
Filed: 1964-06-30
Abstract: The range of operating voltage is adjusted by altering the flexibility of biasing a blade spring 5 carried by armature 4 and the operating voltage within the selected range is altered by varying the tension of the spring. Adjustment of stop 18 carried by a spring 16 alters the tension of spring 5 and adjustment of screw 17 alters the effective length and hence flexibility of blade 5. In an alternative embodiment a member deformable lengthwise and perpendicular to the blade provides the two adjustments. Alternatively a rotary cam with three segments lying in different planes to bear on blade 5 at different points provides the necessary adjustments. In another arrangement the blade spring 5 is of triangular section and is adjustable on the armature to engage a rotary cam with different parts of its width. As a modification the range may be varied by using interchangeable rotary cams which engage blade 5 at different parts of its length.

Title: Process for producing high impact strength graft copolymers with low molecular weight rubbers
IPC: C08F291/02
Filed: 1967-06-14
Abstract: A graft interpolymer composition comprises a rigid polymeric matrix having particles of a graft polymer dispersed therethrough, said particles having a natural or synthetic rubber substrate having a viscosity average molecular weight of from 30,000 to 110,000 and a superstrate of a polymer of a monoethylenically unsaturated monomer, and a particle size of from 0À7 to 20À0 microns. It is formed by mixing the rubber with the superstrate monomer and a preformed polymer to obtain a two-phase system in which the continuous phase comprises a solution of the rubber in the monomer and the dispersed phase comprises a solution of the preformed polymer in said monomer, the rubber forming from 2À0 to 60% by weight of the admixture and the preformed polymer being present in an amount less than that which is required to produce irreversible inversion of phase and is also not more than 7% by weight of the combined total of the weights of said preformed polymer and said monomer less than that amount of polymer which is required to produce such an inversion of phases, and mass polymerizing said admixture at least until inversion of phase has occurred so that the rubber is then present in the disperse phase. Polymerization of the inverted phase admixture may be completed in aqueous suspension. The preferred rubbers are diene rubbers containing 75 to 100% of butadiene and up to 25% of a monoethylenic aromatic monomer and/or an unsaturated nitrile. Preferred superstrate monomers contain at least 5% of such an aromatic monomer and nitrile. The preformed polymer is derived from monomers the same as the graft monomers. The graft polymer may be blended with additional matrix, e.g. a rubber grafted with styrene and acrylonitrile is blended with a vinyl halide or vinyl ester polymer. In the examples, polybutadiene is grafted with styrene, in the presence of polystyrene, in bulk to 30% conversion and then in aqueous suspension to produce beads which are blended with additional polystyrene.

Patent ES-419128-A1 (ES)
Title: Frequency response modifier for fixed-tuned IF amplifiers
IPC: H04N5/44
Filed: 1973-09-27
Abstract: This disclosure depicts methods and apparatus for effectively varying the frequency response of a television IF amplifier whose selectivity is determined by non-variable tuning elements such as SWIFs (surface wave integratable filters). Specifically, a variable bandwidth means, capable of exhibiting either a narrow-band or wide-band frequency response, is coupled to the output of the fixed-tuned IF amplifier. This variable bandwidth means is responsive to a control voltage for selecting one of the frequency response characteristics to be cascaded with the fixed response of the IF amplifier. The selection of the wide-band response allows the overall frequency response characteristic to remain essentially that of the fixed-tuned IF amplifier itself the selection of the narrow-band response causes the overall frequency response characteristic to be changed to an extent dependent on the selectivity of the narrow-band response.
