Abstract: 200,482. Colas, L. J. B. A., Colas, A. P. J., and L'Alfa, Soc. Anon. pour la Fabrication des PÔtes de Cellulose. July 5, 1922, [Convention date]. Alkali-metal compounds, recovering from liquors containing organic matter.-The " black liquor " obtained in the boiling with alkali of vegetable materials such as alfa grass for the production of cellulose pulp is treated with a flocculating agent namely an organic acid such as oxalic or acetic acid or a salt of these acids so as to flocculate the coarser suspended particles which are then removed by suitable means. The separated material referred to as saponified " fatty substances " are treated with an acid, preferably oxalic acid, to liberate the " fatty substances " which are then separated by a solvent such as alcohol, carbon tetrachloride or trichlorethylene and the extracted material containing pectic and vascular substances is separated into its constituents in known ways. The original liquor is then treated with a base such as lime or magnesia or with powdered animal black which absorbs most of the impurities remaining in colloidal or true solution. The separated lime is treated with a solvent to remove a part of the adsorbed matter and is then distilled to remove the remainder. The original liquor is then distilled fractionally to recover volatile substances and when sufficiently concentrated is fed to a calcining furnace in which the soda is recovered in a more or less caustified form. The Specification as open to inspection under Sect. 91 (3) (a), states that the concentrated residual liquor may be mixed with carbon before feeding to the calcining-furnace and is not limited to the particular flocculating agents mentioned. This subject-matter does not appear in the Specification as accepted.

Abstract: 615,916. Electrically - propelled vehicles. BABAT, G. I. March 26, 1946, No. 9267. [Classes 79 (iii) and 79 (iv)] [Also in Group XXXV] An electrically -propelled vehicle which receives current by induction from an outside high-frequency supply system, e.g. an underground network, comprises a frame supported on wheels with steering gear and one or more traction motors, and one or more pick-up loops arranged so as to be in a high frequency electro-magnetic field provided in the line of travel of the vehicle and connected to the motors through suitable rectifying and smoothing means. As shown in Fig. 1, the vehicle comprises a trough-shaped screen 9, of a metal of high electrical conductivity, conductors 10 parallel to the ground, in which the highfrequency currents are induced and which are connected to the lower edge of the end flanges of the screen, together with steering gear, electric motor or motors 5, 6, transmission and wheels, all disposed outside the main screen. The induced H.F. current in the conductors 10 is preferably rectified and passed to a D.C. motor. Various arrangements are described for controlling the speed of the motor, e.g. the closed loop forming the pick-up circuit may comprise several turns or, as shown in Fig. 5, it may be divided into four quarters by two right-angles to one another, the frequency of each quarter being adjustable by variable condensers C1-C4, the current induced in each quarter being separated, rectified and fed through separate variable inductances to a common motor M, variation of the condensers and/or inductances producing the required variation in speed. Instead of using D.C. motors, high frequency A.C. motors may be used, one for each quarter loop, or one motor with four separate windings connected to the four quarter loops. In a further modification, Fig. 10, the pick-up coil may be divided into four quarter loops insulated from one another, each loop being tuned by variable condensers C1-C4, the induced current in each loop being separately rectified and connected in series to the motor 1\1.
