Abstract: An antibody preparation suitable for intravenous administration in humans includes IgG, IgA and at least 5% IgM antibodies by weight of the total amount of antibodies. The preparation is prepared from human plasma, has specific complement activating activity, and, in an in vitro assay with human serum suitable to determine the ability of the antibody preparation to activate complement unspecifically, the antibody preparation generates substantially no C5a and/or substantially no C3a. The antibody preparation can have medical uses.

Abstract: An audio distributor includes a rotor disc rotatably supported by a stationary base. The rotor disc includes a shaft extending within the stationary housing and supporting at least one light emitting diode. Each light emitting diode supported on the shaft is positioned to operably interact with a plurality of photo resistors. Each photo resistor is connected between an input port and an output port for controlling the transfer of the audio signal from the input port to one of a plurality of output ports based on the level of light sensed by the corresponding plurality of photo resistors connected to the circuit for operably receiving the light emitted from the diode supported by the shaft.
