  • Patent number: 5558201
    Abstract: A conveyor apparatus for further transporting individually conveyed, flat products includes a rotatingly driven pulling element and spaced receiving apparatuses that can be loaded and emptied secured to the pulling element for being moved in a conveying direction. The receiving apparatuses each included two side walls which are respectively spaced in the conveying direction and form a receiving chamber having an opening for the products. A mechanism is provided for widening the opening in the receiving chamber of the respective apparatuses for loading product into the chamber and a further mechanism is provided for moving the receiving apparatuses into a hanging position with a predetermined inclination in which the openings are downwardly-oriented so that the product can be ejected through the opening.

  • Patent number: 4602906
    Abstract: A dental instrument for applying powdered polymers has a reservoir for the powdered polymer that is pressurized at least while the polymer is being applied and communicates with a polymer nozzle through a line for conveying the powdered polymer, which contains a polymer-blocking mechanism. A line for conveying liquid monomer connects a liquid-monomer container, which is also pressurized, with a liquid-monomer nozzle. The release of liquid monomer is controlled by another blocking mechanism. The nozzles are positioned at an interval while being aimed at the same operating area.
