  • Patent number: 5755578
    Abstract: A vacuum-cleaner-hose assembly includes a vacuum-cleaner hose (6, 36) and a swivel coupling (3, 33) for coupling the vacuum-cleaner hose (6, 36) to a housing (4) of a vacuum cleaner so as to allow it to be swivelled about a swivel axis (5) and at an angle relative to said swivel axis (5). The swivel coupling (3, 33) has a hose guide (8, 38) which surrounds a flexible portion (24, 54) of the vacuum-cleaner hose (6, 36) and holds said portion of the vacuum-cleaner hose (6, 36) in a curved position. Since the vacuum-cleaner hose is held in a curved position, the connection of the vacuum-cleaner hose to the swivel coupling can be arranged closer to that end of the swivel coupling which is to be connected to the vacuum cleaner, as a result of which the swivel coupling can be smaller and the swivel coupling or at least a combination of the swivel coupling and an adjoining coupling portion of the vacuum-cleaner hose projects less far in relation to the swivel axis of the swivel coupling.

  • Patent number: 5691863
    Abstract: A power feeding device for VTR rotating drums coaxially provided on an end face of a rotating drum, which has magnetic heads in the vicinity of the outer circumferential surface thereof and is rotatably provided coaxially with a stationary drum, adapted to feed power to electronic components incorporated in the rotating drum, in which slits are provided on the slip rings making sliding contact with power feeding brushes in parallel with the axial line of the slip rings. Two slip rings are fixedly fitted to a rotating shaft made of an electrically conductive material in the axial direction in a mutually insulated state, and power is fed to the electronic components from the slip ring on the side remoter from the rotating drum via the rotating shaft.

  • Patent number: 5501604
    Abstract: A flexible band-gear system has an ring gear assembly with bands in electrical contact with and a ring gear in mechanical engagement with corresponding bands and gears of planet gear assemblies which are in turn in electrical contact and geared engagement with a sun gear assembly mounted to a rotating shaft. Electrical power and/or an electrical signal can thus be conducted across a rotating joint which also transfers mechanical power. The flexible band-gear system can also be used in linear applications to transfer electrical power/signal via rolling contact with a linear band. The geared aspect of the system simplifies axial alignment and maintains the relative positions (within the ring annulus) of the planet gears. Electrical power and signal capacity can be varied with the number of planet gears in the system. Multiple channels are added using segmented contact bands and/or multiple contact band layers.

  • Patent number: 5139281
    Abstract: An automotive steering column having slip rings rotatable with a steering shaft and contact brushes on a housing of the steering column for transferring electrical signals between the steering column and a steering wheel rotatable with the steering shaft. The steering shaft is supported on the housing by a pair of longitudinally spaced bearings including an outboard bearing having an inner race on an adapter sleeve rotatable as a unit with the steering shaft. The slip ring is on the adapter sleeve between the spaced bearings and the adapter sleeve defines an annular spacer between the inner race of the outboard bearing and the steering shaft. A passage is defined in the portion of the adapter sleeve defining the annular spacer and a conductor connected to the slip ring traverses the plane of the outboard bearing in the passage.
