Title: Increasing the Bulk Density of Reconstituted Tobacco Sheet
IPC: A24B3/18
Filed: 1967-07-27
Abstract: 1,190,057. Embossing. PHILIP MORRIS Inc. 27 July, 1967 [1 Sept., 1966], No. 34656/67. Heading B6J. [Also in Division D2] The bulk density of constituted tobacco sheet material is increased by applying opposing compressive forces to areas occupying alternate bands in the sheet, the forces being applied in the plane of the sheet so as to cause the sheet to contract along the alternate bands. The sheet is prevented from thickening in the bands by applying pressure to the sheet in a direction normal to the sheet faces. Tobacco sheet 10 (preferably containing 12- 25% by weight of water) is passed between heated, smooth faced roller 12 and endless rubber belt 14, the outer surface 16 of which is contractible and bears a series of transversely spaced longitudinal ribs. In passing from drum 11 to drum 12, face 16 undergoes contraction, subjecting sheet 10 to compressive forces exerted parallel to its faces. The pressure of belt 14 against drum 12 prevents thickening of sheet 10 along the bands 40b, Fig. 5, whilst the non-compacted bands 41b assume an undulating contour, characteristic of a creped sheet. Instead of belt 14 and drum 12, a roller set having a speed differential therebetween, one of the rollers having a discontinuous surface, may be used.

Patent GB-376178-A (GB)
Title: Process for purifying phosphatic liquids
IPC: C05B11/04
Filed: 1931-12-15
Abstract: Phosphate liquors such as those obtained by the decomposition of crude phosphates with acids are purified by precipitating the impurities with organic colloids, for example glue, gelatine, or starch.  The invention may be applied to the process for obtaining diammonium phosphate by decomposing phosphates with sulphuric acid, treating the separated phosphoric acid of about 20 per cent strength with ammonia until neutral to methyl red, and further neutralizing the filtered solution after concentrating.  In this process, colloidal impurities, chiefly ferric phosphate and silica, remain in solution, retarding crystallization of di-ammonium phosphate and passing into the mother lye which is reintroduced into the process. By adding organic colloids to the mother lye before it is recirculated, the impurities and the organic colloids are precipitated together.  When very impure raw materials are <\>aused, it is necessary to effect the precipitation before crystallizing and centrifuging, but addition of the colloid to cold, saturated di-ammonium phosphate liquor gives the best results.  About 1 kgm. of starch, preferably in solution, is sufficient for 1 c. m. of mother lye.  The process is applicable to the recrystallization of contaminated soluble phosphates, or to the treatment of acid solutions or salts obtained by oxidizing phosphorus derived from crude phosphates.

Title: A process of dissolving fuel elements of nuclear reactors
IPC: C01G43/025
Filed: 1962-09-17
Abstract: An element having a core containing uranium dioxide clad with stainless steel or a zirconiumbase metal is immersed in molten lead chloride containing a copper catalyst, e.g. copper, cuprous chloride, or cupric chloride and chlorine is bubbled through to dissolve the element.  The quantity of lead chloride used may be three times that of the weight of uranium dioxide present and it may be maintained in the molten state at a temperature between 500 and 550 DEG C.  The uranium forms uranyl chloride or uranium tetrachloride and the zirconium forms the tetrachloride which volatilizes if the temperature is 550 DEG C.  The concentration of the copper catalyst may be as low as 0.003 M.  The amount of chlorine used is in excess of that stoichiometrically required for the total chlorination of the constituents of the element.  A chlorine flow rate of from 10 to 130 mg./min. is preferred.  Values of the dissolution rates of uranium dioxide and customary cladding materials, e.g. zirconium, stainless steel are given for varying reaction conditions. In a typical example, a zirconium-clad, uranium dioxide-containing fuel rod was dissolved in a molten mixture of lead chloride containing copper through which clorine was passed.  The fuel rod was immersed in stepwise fashion, the temperature of the melt being maintained at 550 DEG C.  Chlorination was continued until the melt solidified, the final composition of the melt being 20.6 mole per cent uranyl chloride, 11.8 mole per cent cuprous and cupric chlorides, and 67.6 mole per cent lead chloride.  Zirconium was separated from the uranium by volatilization as the tetrachloride at 550 DEG C.

Filed: 1972-07-28
Abstract: 1393698 Electro-photographic copying apparatus HOECHST AG 28 July 1972 [30 July 1971 2 June 1972(2)] 35426/72 Heading G2H A method of measuring or measuring and controlling the toner concentration of a developer circulating in an electro-photographic reproduction machine comprises preparing from the circulating developer a sample for measurement the sample being either the developer itself or a material composed of or enriched in the toner component of the developer. The sample is so arranged that the toner therein can be estimated as a proportion of the required toner concentration of the developer. In a measurement step the sample is irradiated by radio-active radiation that is affected by the toner in a manner measurable for estimation of the toner present. The effect of the sample on the radiation is measured and, in any subsequent controlling step, based on the measurement a quantity of further toner is added to the developer to raise the measured toner content to the required value. As shown in Fig. 1 the zone where developer collects in the cascade apparatus there is located on a holder 15 a radio-active preparation 16, radiation from which is reduced in strength by the collected developer material 8 and by the wall of the hopper which is thin at this point; the radiation then strikes a detector 18, and the arrangement is such that signals from this detector control the supply of toner. The reduction in the strength of the radiation depends upon the concentration of toner in the developer material.
