Abstract: MAGNETO-ALTERNATOR WITH MAGNETO ENERGY LIMITING     Abstract of the Disclosure A magneto-alternator has a plurality of alter-nator coils for lighting or the like and a main ignition coil for a breaker-point ignition.  Stator laminations are arranged so that the ignition coil is between two alternator coils and each coil is effectively on an E-shaped core with an outer leg of each E-shaped core being shared with an adjacent coil.  The flywheel has a plurality of ceramic magnets having a high potential energy so that a high alternator output is developed.  The center core leg of the E core on which the ignition coil is mounted has a large air gap relative to the air gaps at the other core legs to compensate for the high energy of the magnets and thereby limit current at the breaker points.  The large air gap also makes the magneto output insensitive to production tolerances in the air gap.     i.

Abstract: ABSTRACT            An electric motor having rotational speed regulation.       Electric motors which are used for instance as driving motors for drilling and cutting implements incorporated in the handle of such implements, are subjected to strongly varying loads. This puts heavy demands to the regulation system of the motor. In a regulation system the signals which are provided by detectors (22) for currently sensing the position of the rotor relative to the stator, are supplied to a pulse generator (44, 46) which provides a pulse frequency being uniquely associated with the period of the varying detector signal. This pulse signal is supplied to a frequency-to-voltage converter (48) which provides an output signal being supplied to a differential amplifier (50) as one input signal thereof, the other input signal being a reference DC voltage, and the output signal of the amplifier being supplied to a multiplier unit (40, 42) as one input signal thereof, the other input signal being said detector signal. The output signal of the multiplier unit is supplied to the exciting windings (16, 18) of the motor via a power amplifier (54, 56).

Abstract: ABSTRACT OF THE DISCLOSURE          A method of and an apparatus for the treatment of radioactive waste water from a nuclear electricity-generating power plant.  The radioactive waste water containing soluble solids, usually boric acid, is concentrated by evaporation to a solids concentration above that which will form a saturated solution at room temperature, whereupon the resulting con-centrate is introduced into a storage vessel and cooled therein to room temperature.  Solids precipitate and sediment in this vessel and water is decanted from the sediment and recycled to the evaporator where the process is repeated.  The process allows the amount of waste in terms of the original material treated which must be stored for a given prolonged period, say between one half and three quarters of a year, for radioactive decay prior to packaging of the waste to be significantly reduced by comparison with earlier systems.

Abstract: ABSTRACT OF THE DISCLOSURE     A spigot assembly for attaching a knuckle of a vehicle to a relatively movable part of the vehicle by way of a bushing having a bore and ends adapted to be held within the knuckle.  The major parts of the assembly include a spigot part having a base arranged to be rigidly secured to the vehicle part and a projection extending from the base.  The projection includes a first pair of annular surfaces facing axially outwardly of the projection and having a bore coaxial with the first pair of annular surfaces, the annular surfaces being spaced apart along the bore.  A cap part is provided having a second pair of annular surfaces complementary to and engageable with those of the projection and having a bore coaxial with the annular surfaces of the cap part.  Bolt means are receivable in the bores for fastening the spigot and cap parts tightly together with the first and second pairs of the annular surfaces engaged with one another.  These first and second annular pairs of surfaces, by virtue of their axially spaced relationship, serve to transmit any bending moments applied by the bushing to the cap part directly to the spigot part so that the bolt means is not subjected to bending stresses.

Abstract: ABSTRACT OF THE DISCLOSURE Carbonaceous solids are partially gaified in a primary fluidized bed gasification zone to form an effluent gas containing entrained fines, including carbon-containing fines.  The entrained fines are separated from the effluent gas and then introduced into a secondary fluidized bed gasification zone which contains a plurality of magnetizable particles, at least a portion of the fluidized bed within said secondary gasification zone being stabilized by the application of a magnetic field.  Unconverted solids from the primary gasification zone, e.g., char and ash, are also introduced into the secondary gasification zone and, along with the entrained fines, are retained and gasified therein.          Stabilizing the fluidized bed within the secondary gasification zone prevents loss of the carbonaceous solids from said zone which, in turn, results in substantially complete gasification of the carbon present in the carbonaceous solids feed introduced into the primary gasification zone.  In a preferred embodiment, the fluidized bed within the secondary gasification zone contains a plurality of separate discrete magnetizable particles and is stabilized by the application of a substantially uniform magnetic field oriented colinear with the direction of gas flow, said gas flow being maintained at a superficial velocity such that the fluidized bed is free of bubbles over essentially the entire bed volume.
