Patent number: 8167598Abstract: A filling shoe for rotary tablet presses, comprising a filling shoe housing with at least one discharge opening for a starting product which is to be compressed and with a seal for sealing the gap between the die plate and filling shoe housing, which seal can be fastened exchangeably to a bottom wall of the filling shoe housing. In order to make it possible to achieve shorter downtimes when changing the seals, the seal in the mounted state is fastened to the bottom wall by means of magnetic force. Changing the seal can then take place, if appropriate even without any further aids, by overcoming the magnetic holding force and replacing the seal with a new seal. The invention also relates to the seal for sealing the gap, which seal can be fastened according to the invention by means of magnetic elements.Type: GrantFiled: February 6, 2008Date of Patent: May 1, 2012Assignee: IMA Kilian GmbH & Co. KGInventor: Hans Krämer

Patent number: 8162638Abstract: The apparatus may include moveable partitions that may be positioned in a side-by-side arrangement. The partitions may be moveable with respect to each other to facilitate installation of liners and reinforcing material and the removal of the concrete structures from the apparatus after the concrete has hardened. Cavities may be defined between the partitions for receiving concrete to form panels for use in barriers, walls and other structures. Removable liners may be temporarily secured to the partitions in a manner that does not comprise the integrity of the liners. Further, the liners may be secured to the partitions utilizing a combination of mechanical and magnetic coupling. The liners may also include a molded portion for forming surface treatments in the panels. Removable bulkheads placed into the cavities allow the dimensions of the cavities to be variable to thereby permit the formation of panels of different dimensions using the same partitions.Type: GrantFiled: January 8, 2009Date of Patent: April 24, 2012Assignee: Intellectual Property Management LLCInventors: Gale J.
