An electron beam generator, for example for electron beam furnaces with a power of at least 500 kw, comprises a cathode 2 having a concave ribbon-shaped emissive surface which is arcuately curved in two directions at right angles to one another out of a plane of the ribbon which extending transversely to the electron beam axis, the cathode being heated by a pulse cathode arrangement 1, pre-focusing of the beam being effected as a result of the concavity of the emissive surface of the cathode, the shape of the focusing electrode 20, the shape of the anode 4 and as a result of the spacing between the cathode and the focusing electrode, the electron beam being finally focused and guided by means of magnetic lenses 8, 11, 13 which are rotationally symmetrical and which do not subject the electron beam to an ultimate rotation. The emissive surface of the cathode has a radius of curvature r 1  transverse to the general axis of the strip-shaped cathode throughout the length of the cathode, and a radius of curvature r 2  in the direction of this axis either throughout the length or only at the two ends of the cathode with a straight portion therebetween. A beam of rectangular cross-section is produced, the pole shoe bores of the rotationally symmetrical magnetic lenses having a diameter equal to the longer side of the beam. A plurality of ribbonshaped cathodes are arranged alongside each other to form a composite cathode, the emissive surfaces being concentrically disposed relative to apertures formed in the focusing electrode and anode. The focusing electrode and anode are water cooled by pipes or holes arranged in or on the electrodes. The beam furnace is evacuated by several vacuum pumps with pressure stage diaphrams between envelope sections, the ions formed due to bombardment of residual gas molecules by the electron beam being collected by an ion trap 25 (Fig. 9, not shown) situated behind the pulse cathode.

Light control apparatus comprises a body having a boundary surface between two media of different refractive index, means for directing a beam of light through the body at such an angle of incidence to the boundary that total reflection takes place and means for varying the relative values of the refractive indices of the two media. In the embodiment shown a narrow parallel beam of light from source 1 is passed through a block 5 by internal reflection (see ray 6) and the emergent beam is reflected by a mirror 7 on to one or more photoconductor in an array 16. The block 5 is formed from a material e.g. carbon disulphide, potassium dehydrogen phosphate, which changes its refractive index in the presence of an electric field, and the block is placed between two electrodes 11,12 which will produce such a field when switch 13 is closed.

Abstract: Composition of an unsaturated polyester resin, sodium silicate and dolomite as in the parent Specification, characterized in that the amount of polyester resin is 10 to 50% by weight of the total composition and the amount of dolomite is 1 to 3 times the amount of polyester resin in the case of non-expanded material and up to 7 times the amount of polyester resin in the case of expanded material. The amount of sodium silicate is preferably 30 to 44% of the weight of the polyester resin.  When used in powder form the sodium silicate which may have a weight ratio of Si:Na of 2:1 to 3.5:1, is mixed with accelerator and polyester resin and to this mixture styrene may be added, followed by a silicone, dolomite, fluosilicate and a polymerization catalyst and the mixture is then polymerized. When floor coverings e.g. tiles, are required, silica is added to the above composition.  In an embodiment of the invention liquid sodium silicate in aqueous solution is used.  First the fluosilicate is diluted in the aqueous solution of sodium silicate, then the polyester resin, catalyst, accelerator and styrene are mixed and added dropwise with shaking to the aqueous solution. Silicone and dolomite are then added.  An expanded material can be prepared from the above compositions, for example by adding powdered aluminium in an amount of 1 to 5 gm. per 100 grams of liquid sodium silicate. Glass fibres may be added.

Suitable bacteria are selected from the species Bacillus and Bacteridium as defined by Prevot and Micrococcus and Brevibacterium as defined by Bergey; deposition numbers and morphological and phoprological characterics of suitable strains are listed; suitable strains may be obtained by selecting those that will grow on a medium containing 1À17% yeast 0À1% acetonitrile and 2À5% gelose. A variety of nitriles may be hydrolysed, e.g. simple nitriles (acetonitrile), α-aminonitriles (α-aminopropionitrile, α - amino - γ - methylthiobutyronitrile, α - aminobutyronitrile, aminoacetonitrile), α - hydroxynitriles (lactonitrile, hydroxyacetonitrile), # - aminonitriles (γ - aminopropionitrile), dinitriles (malonitrile), α - unsaturated nitriles (acrylonitrile) and benzonitriles (homoveratric nitrile). The solution is preferably rendered slightly basic (e.g. to pH 8) with potash or ammonia. In examples, glycine, a and # alanine lactic acid and methionine are prepared; the nitrile precursors of the last two are syntheized in situ (lactonitrile from acetaldehyde and hydrocyanic acid and α-amino-γ-methylthio-butyronitrile from γ-methylthiopropionaldehyde, ammonia and alkali cyanide). After removing the cells, e.g. by centrifuging, the product is recovered as free acid or salt (e.g. ammonium lactate) by conventional methods.
