Abstract: 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.

Abstract: The technical field of the invention relates to magnetic sealing devices used for transfer of torque involving rotating parts. Industries that deal in chemicals and pharmaceutics have a requirement to mix materials such as gases and liquids. This is carried out by mixers and agitators and similar other equipment. All devices involve a shaft that comes out of the body of the equipment, that is to say it pierces the equipment. The location at which the shaft enters the equipment is a potential point of leakage. One of the technical problems that the present invention tackles is that of providing a secure sealing that will reduce leakage. The magnetic seal assembly disclosed in the present invention provides a magnetic sealing device that gives a safe, trouble- free, robust, and leak-proof contactless seal for agitator drives and similar equipment used for industrial scale applications.

Abstract: A device for preventing rattling of a door window glass for vehicles. In an activated condition, i.e. upon the upward and downward movement of the window glass, smoother upward and downward movement of the window glass is enabled, thereby eliminating noise due to frictional contact between the window glass and the weatherstrip. In an inactivated or stopped condition of the window glass, the inside walls of the weatherstrip are supportedly brought into close contact with the surfaces of the window glass, thereby also eliminating noise due to rattling of the window glass caused by external factors such as wind, etc.

Abstract: A sealing member to be attached along a periphery of a door with a continuous good sealing performance against a facing opening portion even in a corner of the periphery of the door. A bar-shaped magnet is provided in a tubular seal portion of the sealing member so as to extend in a longitudinal direction thereof in close contact with an inside surface of a contacting part of a seal wall, which contacts the facing opening portion. The bar-shaped magnet has a cross-sectional shape of which the width gradually decreases from the side of the contacting part of the seal wall inwardly of the tubular seal portion, thereby reducing the cross-sectional area of the magnet, and enabling the magnet to be readily bent along a corner of the periphery of the door. And the bar-shaped magnet has an outwardly curving contacting surface, which contacts the contacting part of the seal wall, thereby improving contacting properties between the sealing member and a corner of the opening portion.
