Patent LV-14271-B (LV)
Title: Synchronous generator with permanent magnets
Inventor: PUGAČEVS Vladislavs
IPC: H02K1/06
Filed: 2010-12-08
Abstract: The synchronous generator with permanent magnets on the rotor and concentrated coils 13 of the armature winding on the stator teeth 1-12 has been proposed. In this generator the number of magnets 15 and 16 on the rotor 14 is limited, for example, pm=2. Thus, on the poles of the magnets turned to the stator, pole pieces 17 with teeth 18 on them are located regularly with step tr. At width tr of slots between the teeth of pole piece, the width of a slots between teeth of adjacent pole pieces is increased by value ?b=tr(0,5+k) where k is integer, including zero. The specified increase of slots is necessary for the prevention of an additional phase shift of EMF in the coil at its transition from an operative range of a magnet of one polarity into an operative range of a magnet of the opposite polarity. The ratio of the stator's and the rotor's teeth number is chosen in order to provide an opportunity of formation of an armature winding with the necessary number of phases. For example, for formation of three-phase winding on twelve stator teeth (Zs=12), at two permanent magnets (pm=2) and three teeth on the pole piece (Zr=3), the number of pole pairs is equal to p=pm(Zr+0.5) In this case, the phase shift between EMF of neighbouring teeth is equal to ?=3600p/Zs=2100. At such a shift, at series-opposition connection of four coils in one phase a symmetric three-phase system can be generated. When the rotor with tooth-wise pole pieces ?is revolving, magnetic flux that is excited by linkage of permanet magnets with coil windings are pulsing from maximal value to minimal value, creating in these coils electromotive EMF. At the corresponding connection of coils shown in Fig.1 , three-phase EMF system is formed. Tooth-wise structure of pole pieces in conformity with the invention allows not only to increase the frequency of the current at limited number of magnets, but also to provide concentration of magnetic flux in the air-gap. In this case a possibility to decrease magnet sizes and to use cheaper magnets appears, e.g., on the base of barium ferrite. Thus, the offered technical solution provides the essential simplification of the design and manufacturing techniques of the generator, as well as its cost decrease.

Patent SE-360026-B (SE)
Inventor: SVANTESON S
IPC: B03D1/24
Filed: 1971-02-09
Abstract: In the purification of liquids by flotation, a mixture of gas and liquid is subjected to sufficient pressure for the gas to dissolve in the liquid and form a solution of the gas and the liquid. The solution of gas and liquid without any substantial change in pressure is introduced at a low velocity to the body of polluted liquid in a flotation tank. Initially no gas bubbles are formed. As the solution rises slowly in the tank and it is subjected to a gradually lower pressure, gas bubbles are formed in a gentle manner. Due to the slow rate at which this takes place the gas bubbles will be very small. Since a great quantity of gas is dissolved in the liquid, a large quantity of gas bubbles will be formed. All of these factors contribute to an effective purification of polluted liquids by flotation.

Abstract: A method of recovering fluorine, e.g. as hydrogen fluoride, from wastes of aluminum electrolysis furnaces, chemisorbents, adsorbents or absorbents, etc. in which the fluorine-containing material is subjected to pyrohydrolysis in an expanded fluid bed and the HF-containing gas is subjected to condensation or scrubbing for the removal of the HF therefrom. According to the invention, the exhaust gases from the fluidized bed are cooled by direct contact with solids which can be circulated in a separate cycle and are themselves cooled in a cooler, e.g. by contact with gas which is to be fed to the expanded fluidized bed. The circulated solids thus allow recovery of the sensible heat of the gas without diluting it.

Title: Splice cassette housing for optical waveguides
IPC: G02B6/44
Filed: 1987-11-27
Abstract: A splice cassette housing for optical waveguides has to be brought from an installation position, e.g. a socket-type housing, to a splice position. The incoming and outgoing optical waveguide cables fed with known splice cassette housings along the longitudinal sidewalls are disadvantageous for the free mobility of the splice cassette housing. In order to achieve a high degree of freedom in the mobility of the splice cassette housing, the incoming and outgoing optical waveguide cables 8 and 9 are usually fed separately from each other to the splice cassette housing in a common axis within a flexible hose. Further, a groove-type guide channel 11 in the shape of a member "9" is provided in the bottom 6 of the housing for a change in direction of one of the optical waveguide cables by 180 DEG , in order to be able to feed the individual optical waveguides again from opposed directions to the splice position. The splice cassette housing is suitable for applications especially in cable-terminal boxes, but also in cable distributors and the like for glass-fiber cables.
