Title: Improvements relating to processes for the production of fatty acids
IPC: C11B13/02
Filed: 1955-08-24
Abstract: In the production of fatty acids by treating a soap-containing mass with mineral acid, a dispersing agent is introduced prior to or during acidulation to accelerate the action on the mass of the acid and the separation into phases of the resultant product. The soap-containing mass may comprise soap produced by saponification of fatty oils, soapstock, or saponified gumcontaining fatty oil produced in degumming fatty oils.  In the case of soapstock, the oil contained therein is also preferably saponified.  The soap may first be washed or grained in known manner with an electrolyte.  The mineral acid may be sulphuric or hydrochloric acid.  The dispersing agent is preferably used in aqueous solution and may be a naphthalene sulphonate in which two or more naphthalene nuclei are joined by an alkylene group, such as a product produced by heating naphthalene, formaldehyde and sulphuric acid; a tertiary acetylenic glycol, such as 2, 5 - dimethyl - 3 hexyne - 2, 5 diol or 3, 6 - dimethyl - 4 - octyne- 3, 6 diol; quebracho extract; a sodium hexametaphosphate type dispersing agent; or a liqnin derivative such as a liqnosulphonate. Specified anti-foaming agents may also be added, if necessary.  A detailed description of the process and suitable plant are given. The acidulation may take place between 100 DEG  and 350 DEG F.  The process may be batch or continuous, and the separation of the fatty acids from the reaction liquor may be effected by gravity or centrifuging.

Title: Moderator structure for the core of a molten-salt reactor

Filed: 1976-06-17
Abstract: 1505471 Molten-salt reactors ELECTRICITE DE FRANCE (SERVICE NATIONAL) and PECHINEY UGINE KUHLMANN 17 June 1976 [26 June 1975 9 Oct 1975] 25178/76 Heading G6C The moderator structure of a molten-salt nuclear reactor is composed of a stack of separate nodules arranged in contact with each other within the structure. The nodules may comprise graphite spheres arranged within the inner and outer cores of the moderator structure which is surrounded by bottom and lateral reflectors and a top shield, Fig. 1. The spheres may be fed into the moderator by means of a shoot and removed by a pneumatic or hydraulic sucking device. Alternatively the nodules may comprise prismatic blocks of hexagonal crosssection stacked in columns which are positioned adjacent each other within the moderator structure, Fig. 4. Each prismatic nodule has a series of channels 40, 42 which are aligned with similar channels in adjacent nodules in each column. A central channel 42 in each column permits a hollow rod 66, Fig. 7, to be inserted in a column the end of which has a releasable fastener to retain the nodules thereon for loading into the reactor. The rods may be mounted in a plate so that the nodules of all the columns may be raised or lowered from or into the reactor as a whole. The fastener means on the ends of the rods may be pneumatic or mechanical and capable of release to enable the rods to be removed after insertion of the nodules. The nodules can be removed by floating them in liquid, after the reactor control rods and their graphite columns have been removed, and by using a device, such as a grab, for removing them from the liquid. The bottom of the reactor has an inlet to permit the molten salt to flow into the moderator. In the case of the prismatic nodules the lower one of each column has a funnel opening 44 to permit the salt to flow into the channels 40, 42. A further modified moderator structure may comprise an inner core of prismatic nodules surrounded by an outer core of spherical nodules.

Title: Generator aggregate intended for variable speed operation

Filed: 1964-06-18
Abstract: 1,060,625. Induction generators. ALLM€NNA SVENSKA ELEKTRISKA A.B. June 18, 1964 [June 20, 1963], No. 25215/64. Headings H2A and H2F. [Also in Division H3] An induction generator which provides a constant frequency at bus-bars 5 at variable speed by means of slip-frequency excitation supplied by an inverter system on the rotor, consists of an output machine 1, 2 and excitation machine 3, 4, wound with different polenumbers in the same stator and rotor cores. The inverter system is fed from D.C. bars 12, 13 connected, through rectifiers 14, to the exciter output windings U, V, W. The exciter field windings r, t, are energized from a source 7 which is controlled partly by a frequency picked up by winding S and partly by a comparison made at 11 between the generated frequency at 5 and a reference frequency. The magnetizing current fed to windings r and t is arranged to be inversely dependent on the rotor speed so that the rectified output at 12 and 13 is uniformly above the back-e.m.f. of windings R, S and T. Speed-sensing is done by means of a resistive shunt 30 across one phase u of the exciter rotor to produce a singlephase asymmetry which is picked up by stator winding s. The inverter is controlled by intermediate D.C. potentials at bars 20, 21, 22 derived from resistance divider 16, 17, 18, 19 the central bar being neutral. The inverter consists of six identical sections, one, 23R-28R, being typical: when the voltage generated by phase R is greater than the potential across capacitor 23R derived from line 21, current flows through diode 24R to the ignition electrode of thyristor 26R which then ignites to allow current to flow from bar 12 via diode 25R into the winding R in opposition to its generated voltage. The thyristor ceases to be conducting when its current is drawn off by operation of the next phase thyristor 265, and it cannot re-ignite until condenser 23R is recharged through resistor 27R and diode 28R.
