  • Patent number: 5245602
    Abstract: A front loading disc player for automatically delivering a disc onto a turntable and playing back the disc includes a disc delivery mechanism for delivering the disc. The disc delivery mechanisms has two trays for carrying respective discs, juxtaposed in a direction substantially normal to the disc carrying surface of the turntable and movable into a projected position out of the player housing and a retracted position in the player housing, and a guide and driver means for guiding and moving the trays into the playback position, the retracted position, and the projected position. While one of the trays is in the playback position, the other tray is positioned in either the stored position or the projected position. While the disc delivered by one of the trays onto the turntable is being played back, therefore, the disc on the other tray can be replaced with a new disc, so that a number of discs can successively be played back.

  • Patent number: 4189474
    Abstract: The present invention is directed to an iron complex used in treatment of iron-deficiency anemia. The complex is formed by reacting a reactive polyiron (III) olated compound with dextrin and at least one hydroxycarboxylic acid. A dextrin-hydroxycarboxylato-polyiron (III) olated complex is produced. The reaction product contains substantially no free iron. Iron concentration is between about 35 and 47%. The complex can be administered non-orally.The compound of the subject invention has advantages over prior art compounds. Specifically, the subject complex has a high iron content, is thermally stable, and can be preserved. It may be administered intravenously without accumulating in the blood of an animal or damaging its tissue. No serious side effects result from use of the subject complex.
