    摘要： The invention relates to a generator arrangement, particularly in ignition system for internal combustion engines. The arrangement is composed of a multi-leg core (9) of magnetically conducting material having its legs (10-17) radially projecting towards a cooperating magneto flywheel (1). The magneto flywheel has one section (5) of an extension corresponding to two core legs and with an unsymmetrical magnet flux (between 4 and 6), and one section having as many north poles as south poles. The legs carry windings (18-25) uniformly wound and connected into groups. One group comprises two windings (18, 25) interconnected such that they only emit an induced voltage (28, 29) when passing the borders or ends of the unsymmetrical section. The second group (19-24) emits an induced combined voltage. The voltage of said first mentioned group controls the ignition process, whereas the second group charges a condenser, component of the ignition system.

    摘要： Method and means of operating an adjusting apparatus (4) for an adjustable device by means of a tool (3), which is mechanically activated by a moving element (1) interacting magnetically with an electromagnet (2) energized by current pulses controlled by a computer program. Several tools (3) and associated electromagnets may be arranged to operate the adjusting apparatus (4) in one or more directions at different torques and operating speeds for different directions of operation and/or positions of adjustment.

    摘要： The invention relates to an arrangement in diaphragm pumps where a diaphragm (8) is to be set in vibration or oscillation by means of a driving element (9), e.g. of piezoelectrical or electromagnetical type, said diaphragm closing an open side of a casing (1) having an inlet (10) for fluid and said diaphragm (8) presenting at least one hole (11) through which on vibration of the diaphragm fluid is intended to be ejected. The novelty lies in that inside the casing (1) there is guidedly and displaceably arranged a spring biassed plunger or body (12) said plunger or body (12) being movable towards and from a portion (15) of the diaphragm presenting the hole or the holes (11), wherein the plunger of body (12) in its rest position is arranged to essentially sealingly engage the face of the diaphragm facing inwardly into the casing and close the hole or the holes (11) therein.

    摘要： This invention relates to a method and system for generating energy/power in a capacitive discharge ignition system, said system comprising at least one charge winding (L) which by means of a fly wheel and via a first rectifier device (D1) charges a charge capacitor (C1) connected to a primary winding (P) of an ignition voltage transformer (30) in order to provide said primary winding (P) with energy for generation of a spark via a secondary winding (S) of said transformer (30), wherein a voltage control/switching unit (10) is arranged to enable output of energy (Out21) from said primary winding (P).
