Patent number: 4399931Abstract: A dry matter dispensing device comprising a hopper having a paddle pivoted between the front and rear walls, the paddle is oscillated to sweep the contents from the opposite ends of an arcuate, concave tray with each stroke thereof. The dry material slides down a pair of adjustably sloped panels on opposite sides of that paddle so that, as the paddle sweeps material in front of it on each stroke, more is dropping down the sloped panel behind it to pile up on the concave tray. Hence, a measured amount of the dry material is delivered by setting the length and number of paddle strokes. The adjustment of the sloping panels is made to ensure free flow to the concave tray without the material bridging or escaping prematurely from the tray.Type: GrantFiled: March 24, 1981Date of Patent: August 23, 1983Inventor: Richard E. Maddalena

Patent number: 4033730Abstract: Particulate solids are fed into a pressure reactor operated under a pressure of 5-150 bars by means of a guide cylinder which is secured to the reactor and surrounds the reactor inlet. The guide cylinder is adapted to be closed and a stationary feed conduit is directed towards the guide cylinder. A cylinder container, which is gastightly guided in the guide cylinder and has a bottom which is adapted to be closed, is moved up and down in the guide cylinder and when the bottom of the cylinder is open and the reactor inlet is closed the material flows out of the container into the guide cylinder whereas the bottom of the container is closed and the same is moved toward the open reactor inlet to displace gases into the reactor. The device for carrying out the process includes a guide cylinder secured to the reactor and surrounding the reactor inlet. The guide cylinder is adapted to be closed.Type: GrantFiled: June 4, 1976Date of Patent: July 5, 1977Assignee: Metallgesellschaft AktiengesellschaftInventors: Gerhard Baron, Carl Hafke, Dietrich Engler, Rainer Reimert, Eberhard Blaum
