Abstract: 299,357. Riebeck'sche Montanwerke Akt.-Ges., A. Oct. 24, 1057, [Convention date]. Wares, purifying.-The process of refining waxes by adsorbents while the wax is in solution is applied to the refining of carnauba and candelila waxes. In an example, a solution of 50 lb. of carnauba wax in 400 lb. of ethyl acetate is gently boiled and stirred with 1.25 lb. of " Carboraffin " for about an hour. The mixture is filtered or centrifuged to separate the carbon; the solvent is then distilled off. The decolorizing agent is freed from retained wax by solvents, and regenerated by heating to incandescence in a current of carbon dioxide or in other known manner. The carbon may also be added in stages, preferably on the counter-current principle. Solvents specified are methyl alcohol and its homologues, their esters and ethers, esters and ethers of glycol or other polyhydric alcohol, and butanone or other ketone. The Specification as open to inspection under Sect. 91 (3) (a) describes the treatment of like vegetable waxes. This subject-matter does not appear in the Specification as accepted.

Abstract: 911,189. Dielectric heating. RADYNE Ltd. May 4, 1961 [May 9, 1960], No. 16326/60. Class 39 (3). The upper electrode of a dielectric heating chamber, which is not mounted on the pivoted lid of the chamber, is movable between a lower working position, to which it is forced by lowering of the lid, and an upper position, towards which it is resiliently urged, the electrode being maintained horizontal throughout its movement between the two positions. The upper electrode 28 is biased upwards by spring 38 acting on the lower of its two support members, 32 and 34, which are pivoted on member 36, the upward movement being limited by stop 40. The lid 10, hinged along line 14, is urged open by spring 16, and forces electrode 28 to its lower position upon closure (Fig. 1, not shown), by the abutment of roller 44 on projection 50, wheel 52 permitting adjustment of the lower electrode position. The tendency of the springs 62, mounted in the continuous channel 56 of conductive material which runs round the edge of the lid, to force the lid open from the closed position by co-operation with the steel tube 60 mounted on the conductive lip 58, is counteracted, while heating is in progress, by the cooperation of electromagnet 62 with magnetizable member 66 on the lid. Panels 74 and 76, and similar panels in the lid, are of perforated metal, and permit observation and ventilation; electrical shielding along the hinge line 14 is provided by conductive strip 19. The lower, fixed, electrode 22 is mounted on conductors 27 which pass up through the four insulators 24. The glass cylinder 78 shields the operator from dirt.

The spring bar has transverse lugs 12 with slits 13 to receive tongues 21 on the lower edges of the transverse members, these tongues being riveted over to secure them. The longitudinal sections have bottom projections 28 fitting in longitudinal slits 14 in the spring bar and side tongues 26 fitting in overlapping relation in notches 19 in the transverse walls. In addition they are formed with hook-like projections 27 at the top to engage in overlapping relation over slots 18 in the upper edges of the transverse walls. The end longitudinal sections have projections and hooks on one edge only, the other edge fitting in slits in the end of the spring bar. Levers 16 pivoted in ears in the spring bar by pivots 15, Fig. 11, passing through the end longitudinal sections are shaped so as initially to force the tray rim away from the grid to release it and then to contact at 31 with the spring bar to flex it in the continued opening movement of the levers. In a modification the transverse members are of double thickness metal spot-welded together near their outer edges only. The upper edges spread apart when the grid is bowed, until the projecting hooks of the longitudinal sections bring them together again. The grid members are preferably of stainless steel, .but may be of brass, aluminium or of non-metallic material.
