Abstract: A vehicle supercharger assembly (110) comprises a dual generator comprising first and second co-axial relatively rotatable armatures (14a, 14b), and a first disengageable clutch (32) between the armatures (14a, 14), said first armature (14a) being adapted for permanent drive from a source of motive power, and said second armature (14b) being driven by said first armature (14a) on engagement of said first clutch (32); a supercharcharger impeller (24), the second armature (14b) driving the impeller (24) mechanically via a gear train; an electric motor coupled to the gear train and operable to adjust the rotational speed of the impeller (24); wherein, in use, the electric motor is electrically driven on demand from a generator comprising the second armature (14b).

Abstract: The present invention relates to a vehicle supercharger assembly (14) comprising a generator comprising a first armature (14) being adapted for permanent drive from a source of motive power; a supercharger impeller (24) arranged to be driven via a gear train; an electric motor comprising a second armature (28), said second armature (28) being coupled to the gear train; a first clutch (32) for selectively coupling the first armature (14) to the gear train for driving the supercharger impeller (24) in a first mode of operation in which the electric motor is operable to adjust the speed of the supercharger impeller (24); and a second clutch (34), operable when said first armature (14) is coupled to the gear train, for selectively locking the gear train so as to prevent relative rotation of the first and second armatures in a second mode of operation.

Abstract: A method of manufacturing a surface-mount encapsulated reed relay comprises providing metal lead-frame having conductors for connecting the relay to a circuit and insert-moulding a plastics material plate to the lead-frame so that the conductors extend through the plate and are bonded thereto. Unwanted lead-frame parts are cut away on at least one side of the plate, leaving the conductors exposed for the connection thereto of a reed relay capsule and operating coil, whereafter a housing is fitted to the plate so as to embrace the reed relay capsule and operating coil.
