Abstract: As a reversal of previous practice, the annular body of the mold in the unit has an annular case at the bottom thereof, rather than at the top thereof. The case is relatively thick axially of the mold, so as to form the greater portion of the axial length of the mold body at the outer periphery thereof; and at the top thereof, the case has an annular plate thereon, which forms a pair of flanges that overhang the case and enable the metal casting unit to be lowered into an aperture of a casting table from above, and supported on top of the table at the flanges. Meanwhile, the case defines the lower end opening of the mold cavity, and the outlet for liquid coolant that is discharged onto the molten metal body as it emerges from the unit. Commonly, the case is monolithic, and also has an annular sump at the top thereof which is covered by the plate to form a chamber for the coolant in the sump. A graphite casting ring may be circumposed about the inner periphery of the case, to form a liner for the upper end portion of the cavity; and a refractory top ring may be circumposed about the upper end opening of the cavity, to form a hot top for the ring.

Abstract: A fabric sign having a pair of parallel support elements ( 1, 2 ) and a fabric ( 3 ) with two parallel edge portions ( 4, 5 ) for assembly on one each of the support elements, at least one of the support elements comprising a frame profile ( 7 ) with a counter support ( 12 ) having an inner wall section ( 17 ) forming a continuation of said attachment part ( 14 ), an outer, flange-like wall section ( 19 ) with a free supporting end ( 20 ) to form a pivot (A), and an end wall section ( 18 ) connecting the inner and outer wall sections with each other, said wall sections defining between them a clamping pocket ( 25 ), and a clamping profile ( 8 ) for clamping the fabric to the frame profile, which clamping profile has a pressure part ( 28 ) for manual actuation, retaining devices ( 48, 49 ) for retaining the edge portion of the fabric, and an engagement part ( 27 ) arranged to cooperate with the inner and outer wall sections of the counter support when the pressure part is pressed against the attachment part while the clamping profile is turned about said pivot, at the same time creating tensile stress in the fabric. In accordance with the invention the outer wall section of the counter support has an extension that allows the clamping profile to exceed an equilibrium, at which exceeding of the equilibrium the tensile stress acts to move the clamping profile to a locked position in which the clamping profile is in locked engagement with the frame profile, said locked position being maintained by the tensile stress.
