Patent EP-0023037-A1 (EP)
Inventor: LANDGRAF HERMANN
IPC: H02K23/16
Filed: 1980-07-17
Abstract: The invention relates to a small D.C. motor with a permanent magnet stator. In order to be able to change the speed range of the motor within specific limits, according to the invention it is proposed that the stator (4, 5, 22-25) contains at least one bar (22-25), of permanent magnet material, supported in a rotatable manner about an axis (21) which is essentially parallel to the motor axis (20), and furthermore that means of adjustment (14, 15) are provided for twisting the bar (22-25) relative to the directly adjacent stator parts (16-19). By twisting the bar, an opposing field is produced which reduces the total flux and thus allows the speed to be changed. The arrangement is used, in particular, for being able to change the speed range of a small D.C. motor for the drive of dentists' tools (Figure 1). <IMAGE>

Abstract: This invention relates to an auger and to a plow including such auger (17). This specification discloses an auger (17) which when suitably mounted, is suitable for use even at the difficult terrain encountered in typical reforestation operations. An auger (17) in accordance with this disclosure has its axis extending in the direction of movement of the plowand is arranged to rotate in a direction opposing the forward movement of the plow. The auger (17) has a plurality of generally helical turns. Sections of the ground engaging portions around the periphery of the turns have an angle of attack in a plane at a selected angle to the axis of the auger (17) and other sections have angles of attack in planes at a different angle. These ground engaging sections of the periphery are preferably teeth (31) which because of the difference in angles discussed above attack the ground at different cutting angles. The dislodged earth will as is normal with an auger be flung sideways as a furrough is formed, but it will also have a component of motion which is either forward or backwards in relation to the direction of travel of the plow. When, as previously explained the auger (17) is rotating to oppose the direction of the plow, this forward or backward component of motion will depend on the rate of forward movement of the plow less the rearward displacement of particles caused by the auger (17). The motion will be forward if the result is positive and backward if the net result is negative.

Abstract: A driving belt for application on V-shaped pulleys comprising an endless carrier and a plurality of transverse elements abutting against each other with the head sides and slideably assembled on the carrier. The transverse elements are provided with coupling means comprising at least one projection (6) at one head side (2) and substantially corresponding recess(es) (7) at the other head side (3) of a transverse element. 
<??>Around the coupling means there is some clearance (8), i.e. the thickness of the transverse elements (distance between the two head sides of a transverse element) around the coupling means is smaller than the nominal thickness (n) of the transverse element (distance between corresponding head sides of successive transverse elements). In this way an improved engagement of the coupling means can be achieved.

Abstract: Es wird eine Stop-Start-Vorrichtung für einen Fahrzeug-Verbrennungsmotor beschrieben, welcher eine Stop-Taste (66) aufweist, deren Betätigung eine Motorbetriebsunterbrechungsschaltung (28) in einen den Betrieb des Motors unterbrechenden Zustand versetzt. Weiter ist eine Start-Taste (45, 46) vorgesehen, deren Betätigung die Motorbetriebsunterbrechungsschaltung zurücksetzt und einen Anlasserstromkreis (10, 12) so lange schließt, bis der Motor einen vorbestimmten, von einem Motorbetriebserkennungsschalter (20) erkannten Betriebszustand erreicht, bei dem der Anlasserstromkreis unterbrochen wird. Weiter ist eine Bereitschaftsschaltung (36) vorgesehen, welche die Start-Taste erst nach Schließen eines Zündschalters (4) und zusätzlichem Vorliegen des vorbestimmten Betriebszustandes des Motors zum Betätigen des Motorbetriebserkennungsschalters in Funktionsbereitschaft setzt. Damit kann ein versehentliches Anlassen des Motors vermieden werden. Desweiteren ist vorteilhafterweise in Reihe mit der Start-Taste ein Motorstillstandserkennungsschalter (42) geschaltet, mit dem erreicht wird, daß die Start-Taste erst dann zum Anlassen des Motors wirksam ist, wenn der Motor tatsächlich steht. Zusätzlich kann eine Anlasserbetätigungsschaltung (86, 88, 92) vorgesehen sein, welche nach einem Abstellen des Motors mittels der Stop-Taste oberhalb einer bestimmten Geschwindigkeit des Fahrzeugs den Anlasserstromkreis selbsttätig schließt.

Abstract: A branch pipe part is provided with a collar and a downwardly extending skirt, the free end of the branch pipe part comprising a first outwardly extending projection and the lower portion of said pipe part being provided with longitudinal incisions allowing deformation of said lower portion. The outer wall of the space formed by collar and skirt may have apertures for passing a lip of a sealing member. In order to avoid further deformation of the lower portion with incisions after connection with a main conduit, a deformation-preventing bush is pushed into the lower portion and locked by means of a cam. For decreasing the distance between the outer side of a main conduit connected with the branch pipe part, the skirt may be provided with a removable adapting ring, an intermediate part thereof decreasing the distance between the outer side of the main conduit and the free lower end of the skirt. The lower free end or the bottom side of the intermediate part and the outer side of the main conduit tightly engage a part of the sealing member, said sealing member comprising four legs.

Abstract: Control is provided over the casting of iron pipe in a centrifugal casting machine. The initial flow of molten iron from a pouring ladle (10) into a trough (15) actuates an electric eye (40). A second electric eye (42) is actuated when the molten iron has flowed to the end of the trough. The centrifugal casting machine (20) is rolled up to surround the trough, the bell end (32) of the pipe to be formed being at the end of the trough. A computer (44) is utilized to determine the velocity of the iron on a real time basis. This iron flow information is analyzed to calculate the bell flag time by a previously determined algorithm which takes into account the casting machine and the pipe size being cast. The bell flag time is the time in which the molten iron is allowed to flow into the bell section of the pipe being cast, before the casting machine is moved away from the trough end to form the rest of the pipe.

Abstract: Dispositif de distillation dans lequel un groupe de paires de tubes (7) de transfert de chaleur sont entraines de maniere a osciller autour d'un axe vertical passant au travers d'un centre d'oscillation (30), (64-67).

Le courant de fluide tend a adherer a la surface interieure du tube loin du centre d'oscillation pendant qu'il tourne par rapport au tube en reponse au mouvement d'oscillation. Le courant d'ecoulement tournant (6) essuie la surface interieure du tube (7) pour former une pellicule mince (5) qui offre une faible resistance thermique pour faciliter l'evaporation, emporte le residu par son mouvement lateral et emporte le reflux vers le bas avec une restriction moindre.
