Abstract: 352,254. Protractors. DAHLBERG, L. E. M. C., Kristianstad, Sweden. July 10, 1930, No. 20954. [Class 97 (iii).] An angle-measuring instrument comprising a transparent plate has a central hole preferably metal tipped, double angle-graduations extending for 360‹ in both directions from a zero-line, and means for accentuating the zero-line to enable marks along it to be made in any position of the instrument. As shown in Fig. 1 the instrument comprises a square celluloid plate 21 from the centre 22 of which run lines ending in the outer graduated circle 25. The slot 23, parallel to one side of the plate, rims from near the hole 22 to near the periphery, and has a distance scale 28. Lines 29 parallel to the slot 23 permit of adjustment along the meridian. Holes 30 at definite distances from the centre serve for fixing the plate, and the chequered portion 31, Fig. 5, for making sketches. Angles subtended by distant objects may be measured by holding the scale 34 graduated correspondingly to the scale 26 at a definite distance from the eye by means of a strap fastened to the hole 33. The scale 34 is completed by a toothed opening 37. A slot 24 is aligned with the slot 23. The instrument shown in Fig. 5 has a spiral scale 40, having one turn per unit of length and being subdivided into equal arcs by radii. Distances are measured on a map from the centre 22 to the appropriate point on the spiral. The slot 23 may be replaced by a stretched wire, the bevelled edge of an opening in the plate, or by a sharp edge formed on the underside of the plate. The plate may only comprise a portion of the whole circle.

The foam slab 16 is preferably acoustically transparent and extends over the whole of the backing member 11. The backing member 11 may be made of a number of perforated plates joined by adhesive tape 14. Fig. 4 shows a push-pull arrangement in which two membranes 7 are sandwiched between two backing members 11. A foam slab 16 bears against each backing member 11.

Abstract: A phospho-silicate complex of general formula <FORM:0852501/III/1> where R is zirconium, titanium, hafnium or thorium and wherein z is at least 5 x and y is less than x, is prepared by dissolving in water a soluble compound of zirconium, titanium, hafnium or thorium, a soluble phosphate and a soluble silicate and acidifying the solution. z is preferably at least 100 times as large as x and y may be as little as 1/10th of x.  For example a solution of sodium silicate, zirconyl nitrate and trisodium phosphate may be acidified with hydrochloric acid and the phospho-silicate precipitate is then washed with water and with concentrated nitric acid to remove impurities. The zirconium phospho-silicate complex is soluble in hydrofluoric acid; warm saturated oxalic acid will dissolve the zirconium phosphate component leaving sodium silicate.  The complexes are employed to separate plutonium from acid solutions of neutron irradiated uranium (see Group XL(a)).  Specification 826,910 is referred to.
