Title: Gas cooled high temp. reactor has hot gas duct anchored - to side reflector, with piston ring type seal giving three=dimensional movement
Inventor: SCHOENING JOSEF DIPL ING
IPC: G21C1/07
Filed: 1980-10-10
Abstract: Gas-cooled, high-temp. reactor has a cylindrical side reflector (9) of graphite blocks around the core, an annular space (17) outside this reflector traversed by recycled, comparatively cool prim. circuit gas, and a thermally insulated hot gas duct (13) supplied with the gas from a collecting space underneath the core. To provide 3-dimensional movement of the hot gas duct (13) relative to the side reflector (9,19), a metal support frame (27), surrounding the connection point of the hot gas duct (13), is pressed by springs (24) against the side reflector (9), esp. with a close-fitting interface between these two components; this metal support frame (27) has an annular flange (28) projecting into the annular space (17) and encompassing the hot gas duct (13); a number of annular slide blocks (32) of grey cast iron are supported between discs (30) attached to a mounting system (31,33,29) resting on the annular flange (28), the slide blocks (32) being pressed by springs (34) radially towards the hot gas duct (13), where they bear closely against a tubular metal sealing sleeve (35) fitted around the end of the hot gas duct; thus a piston-ring type seal is formed around the end of this duct, which communicates freely with a portion (17) of the annular space, the seal isolating this portion of the annular space from the remaining portion in which cold coolant flows. Full movement in three dimensions between the hot gas duct and the adjacent side reflector, from which it is supported, is possible without unacceptable forces being transmitted to the graphite blocks of the side reflector. Adequate gas sealing is provided, a small leakage being desirable to cool the slide block system.

Title: Apparatus for shredding tyres
Inventor: SCHURR HANS
IPC: B29B17/02
Filed: 1981-03-28
Abstract: In order to increase the shredding output and to reduce the complexity of the equipment and the way of operating it, an approximately horizontal turntable is rotatably mounted by a bearing on a basic frame (12, 13, 14, 16) and has an approximately level supporting surface for bearing the tyre flanks of one side of the tyre. On the turntable there are at least two upright driver profiles, symmetrical with respect to the geometrical axis of rotation (42) of the turntable and perpendicular with respect to the turntable. The said profiles can be rotated with the turntable, are flexurally very rigid, lie on a circle concentric to the axis of rotation (42) and are of a length which is greater than the distance between the turntable and the upper bead. Of the driver profiles, at least one can be moved approximately radially with respect to the axis of rotation (42) and, during this movement, guided in a guide device on the turntable. The driver profiles have on their faces opposite the bead end face driver pins, which can penetrate into the bead end face. By means of a disconnectable power device (29), the driver profile can be urged outwards. A supporting device fixed to the apparatus bears a cutting device, the cutting instrument of which can be moved into the tyre flank facing away from the turntable. The driver profiles are preferably T-profiles, the middle piece of which is situated radially and the driver pins of which protrude from the outside of the crosspiece. The apparatus is suitable in particular for shredding steel belted tyres without undue stress on the equipment used. <IMAGE>
