  • Patent number: 4822300
    Abstract: The invention relates to a device for connecting cable wires to cutting/clamping contacts of dropwire connector banks of telecommunication sytems by means of a press-in tool provided with guide and press-in pieces and an actuating face. In order to allow a connection of a dropwire cable wire that thick insulation jacket in one single operation step to a cutting/clamping contact of the dropwire connector bank, the actuating face of the press-in tool is formed as an application body immediately adjacent to the guide and press-in pieces for a striking or lever tool, in particular a screwdriver. By exerting a striking or lever force on the press-in tool, a dropwire cable wire can, thus, be connected in one single operation step to a cutting/clamping contact of a dropwire connector bank. In a further embodiment of the invention, the press-in tool is formed as a part of the closing plug and serves for the fixation of the thin cable wires in dropwire connector banks.

  • Patent number: 4813328
    Abstract: In the production of a desired musical waveform by combining harmonic components corresponding to respective harmonic orders, each harmonic component value is controlled by a selected cut-off harmonic order qc, level Ha and slope of the formant filter characteristic. The cut-off harmonic order qc, the level Ha and the slope values can each be varied over a predetermined range. Therefore, the slope values of the formant filter characteristic are interpolated to raise resolution, by which it is possible to prevent an abrupt change in the formant filter characteristic and suppress the generation of noise.

  • Patent number: 4813303
    Abstract: A speed reducer construction for use with a drive motor which has a drive motor housing and a drive motor shaft which extends out of the housing comprises a reducer housing which is adapted to be coupled to the drive motor housing and encloses a portion of the motor drive shaft. The motor drive shaft is advantageously journalled in the reducer housing and it carries a worm made of a Nylatron material which is rotatable therewith. An output shaft extends transversely to the drive shaft and is journalled in the reducer housing and it carries a sleeve which is keyed thereto for rotation therewith. A gear is freely rotatable on the sleeve alongside a collar portion of the sleeve and is in meshing engagement with the worm. The drive of the motor through the worm to the gear and the output shaft is regulatable by a clutching device including a clutch spring which is biased against an end of the gear with a biasing force which is regulated by a torque adjusting wheel which is threaded on the sleeve.

  • Patent number: 4813140
    Abstract: A lawn and bush cutting device comprises a housing mounted for rotation about an axis with a drive shaft fixed to the housing and drivable by a motor for rotating the housing. A wire cylinder is coaxially mounted in the housing and can be held fixed with respect to the housing for rotation therewith. A supply of cutting wire is wound on the wire cylinder, or on a reel rotatably fixed to the wire cylinder. A length of the wire extends out of the housing to act as a cutting tool when the housing rotates. A sleeve member is axially movable in the housing and has helical coupling piece which are coupled to helical piece in the cylinder. Axial movement of the sleeve thus causes relative rotation between the wire cylinder and housing, thus paying out additional lengths of wire from the housing. A ring is axially moveable but rotationally fixed to the sleeve and can be moved downwardly by cable operated member.

  • Patent number: 4811907
    Abstract: A method and apparatus for improving the grinding result of a pressure chamber grinder includes a feeder for feeding material into a pressurized equalizing tank, then transferring the material into a pre-grinder where the material is fluidized by grinding-gas jets. The fluidized material-gas flow is divided by a bisecting device into two component flows and it is accelerated through two accelerating nozzles which are directed toward a impact point of a main grinding chamber. The grinding chamber has an outlet connected to an acceleration tube inlet which is connected at its discharge to a free-flow grinder provided with tangentially directed grinding-gas nozzles. The material which passes through the nozzles is in a ready ground final product form is removed constantly through a centrally located exhaust pipe.

  • Patent number: 4811644
    Abstract: The present invention is directed to an electronic musical instrument which has a circuit for calculating a harmonic function corresponding to a fundamental wave. The electronic musical instrument is provided with a circuit for generating, as the harmonic function, an in-tune function corresponding to an in-tune harmonic, a circuit for generating a phase function which imparts an arbitrary frequency number log to the in-tune harmonic and a circuit for multiplying the in-tune function and the phase function, whereby a tone close to a natural tone of an acoustic musical instrument can be created at a relatively low cost.
