Abstract: Device for dissipation of gases created in the event of a quench of a superconducting magnet has a quench tube and a front sealing element closing the quench tube on the magnet side. The quench tube is sealed by a rear sealing element, and at least one sensor is associated with the tube segment closed by the sealing elements. The measurement values of the sensor represent a measure for the impermeability of the tube segment. The sensor communicates with an alarm emitter via which an alarm signal can be output upon detection of a leakage of the tube segment.

Abstract: A trimming shears for sheets and strips having two shears frames arranged opposite one another and on supports and being rotatable about a central vertical axis. A pair of vertically stacked adjustable roll blades are mounted in each shears frame at diagonally opposite horizontal corners of the shears frames. The roll blade pairs are rotary driven by gears and couplings to cut the sheet or strip edges. The roll blade pairs are adjustable both vertically and horizontally to accommodate different material thicknesses and widths. The roll blade pairs are arranged in the shears frames such that when the shears frames rotate 180.degree. about the central vertical axis, the position of the roll blade pairs is transposed--with the first roll blade pair taking the position of the second roll blade pair.

Abstract: Self-extinguishing thermoplastic polyurethanes contain, as flameproofing agents, one or more organic phosphates and/or one or more organic phosphonates, preferably as a mixture together with melamine derivatives.

Abstract: A blade guide of a guillotine shear for flying transverse parting of strips, particularly steel strips. The shear having a shear housing in which blades fastened to blade supports are movable relative to one another on parallel guide paths for cutting and transversely to the guide paths in the running direction of the strip and at the running speed of the strip. The guide paths are arranged in a guide frame which is movable horizontally in the shear housing and the blade supports in the guide frame can be set in rotation by means of crank mechanisms which are supported in the shear housing and are associated with each blade support.
