IPC: B03B5/62
Filed: 1961-04-27
Abstract: 924,327. Separating solids. SOC. GRENOBLOISE D'ETUDES ET D'APPLICATIONS HYDRAULIQUES SOGREAH, and COMMISSARIAT A L'ENERGIE ATOMIQUE. April 27, 1961 [May 10, 1960], No. 15216/61. Class 117. A mixture of lighter and heavier granular materials is separated into its two components by introducing it through an intake 8 into apparatus into which an upwardly ascending stream of liquid, e.g. water, is introduced through an inlet 7 and which comprises two compartments 1, 2 formed by inner and outer tubes and separated by the wall 3 of the inner tube, there being communication between the two compartments below the bottom end of the inner tube, at 5, and which comprises a perforated bottom 4 through which the liquid ascends, each of the compartments being provided in its upper portion with means for discharging a separated component. The stream of liquid is given a velocity slightly greater than the minimum fluidization velocity of the heavier component, with the result that the part of the stream which ascends the compartment 1 carries the lighter components M2 to the top of the outer tube, leaving an intermediate zone 9 containing a mixture of the two ingredients M1 and M2 near the material intake 8. If the hydrostatic pressures at the lower portions of the fluidized mixtures in the two compartments are substantially equal, the heavier component of the materials sinks to the bottom of the compartment 1, passes through the space 5 and is carried upwards by the part of the liquid stream which ascends the compartment 3. The tops of the inner and outer tubes form weirs D 1 , D 2  over which the separated light and heavy components are discharged respectively. To achieve the required condition, the difference in the levels h 1  and h 2  must be such that the apparent weight per unit cross-sectional area is the same in both compartments. The heights of the weirs D 1 , D 2  are adjustable by slidable portions 10, 11 respectively. The weirs may be replaced by discharge pipes having means for regulating their output, their intakes being at a suitable height whereby the apparent weights per unit cross-sectional area in the two columns may be balanced by increasing or reducing the output from the pipes.

Title: Improvements in means for regulating the voltage of asynchronous generators and in the excitation and control of synchronous generators
IPC: H02K17/42
Filed: 1937-06-07
Abstract: 479,260. Automatic control systems and regulation; induction generators; inductances. BRITISH THOMSON-HOUSTON CO., Ltd. June 7, 1937, No. 15738. Convention date, June 6, 1936. [Classes 35, 38 (ii), and 38 (iv)] A capacity-excited induction generator has its terminal voltage stabilized by means of a saturable-core reactor connected in parallel, its impedance being high at the maximum voltage but being reduced by D.C. saturation to control the effective exciting current. The winding effecting saturation may be supplied from a source responsive to the generator voltage or current, or both. Parallel connected inductances magnetically biassed in opposite senses by the saturating current avoid asymmetry of the A.C. output. Fig. 3 shows an arrangement of windings LD on a single core and connected in parallel to the A.C. terminals of the machine M and at equipotential points to a saturating source G. A reactor may be saturated by a winding connected across the machine terminals in series with a rectifier which may be grid controlled or connected to the secondary winding of a transformer in series with the exciting capacity. Fig. 6 shows an alternator M excited by a coupled self-excited induction generator m through rectifiers GM. The A.C. output is regulated automatically as regards voltage by a saturating winding Ve, and as regards current by a second winding Vi, two grid-controlled rectifiers Gi, oppositely connected, determining the sense of the compounding.

Title: Improvements in or relating to the manufacture of soap and apparatus therefor
IPC: C11D13/04
Filed: 1938-05-27
Abstract: 519,516. Soap ; glycerine. REFINING, Inc. May 27, 1938, No. 15870. Convention date, May 28, 1937. [Class 91] Soap and glycerine are obtained by saponifying at a temperature sufficiently low to prevent discoloration due to traces of unsaponified fat or like, working or otherwise treating the scap-while still below discoloration temperature-to saponify all fat completely, and then heating to a much higher temperature and discharging into a chamber, preferably evacuated, to separate the water and glycerine as vapours. For example, proportioned quantities of fat and alkali are drawn by pumps 7, 8 from containers 5, 6 through preheaters 11, 12 to a mixer 18, and passed by a pump 20 through a heated coil 24 ; the soap is forced through a pipe 28 and a mixer or pump 30 where any residual fat is saponified, and then through a pipe 29 and a heated coil 69 to a pipe 75 and discharged, e.g., from a nozzle 81, into an evacuated chamber 80 ; the soap is withdrawn by air-tight conveyers 103, 106 provided with cooling jackets 109, 110 ; the vapours flow by a pipe 87 to glycerine and water condensers 91, 96 connected to a vacuum pump 100. The mixer 30 may be a, rotary or reciprocating pump, or may be a jacketed screw-conveyer preferably fitted with a perforated transverse plate ; it may be replaced or assisted by increasing the turbulence in the soap stream, e.g., by flowing the soap from the coil 24 to the pipe 28 through the thermostatic control 27 so as suddenly to reverse its direction. Suitable temperatures in the coil 24 are 350-425F., with pressure of 50-250 lb. at a gauge 63. The fat is usually preheated, as by the coil 11, to 200-350F., but it may be 100-400F. ; the alkali is usually preheated to 100-220F. Temperatures of 455-600F. are suitable in the coil 69, preferably such as to vaporize water and at least part of the glycerine at the pressure therein. The soap may be further heated in the chamber 80 by the jacket 83 or/and by injecting steam or gas. Preferably the heat supply in the coil 69 and chamber 80 is such that the anhydrous soap in the conveyer 103 is molten or plastic, but the soap may be removed as powder. A vacuum of 27-28 in. in the chamber 80 is satisfactory when all glycerine is to be removed. Water, perfumes, fillers, and other materials may be added to the soap in the conveyer 106 or later.
