St John Altarpiece The St John Altarpiece (German - "Johannesaltar", "Johannestafel" or "Johannesretabel") is a c. 1455 oil-on-oak wood panel altarpiece by the Early Netherlandish painter Rogier van der Weyden, now in the Gemäldegalerie, Berlin. The triptych is linked to the artist's earlier "Miraflores Altarpiece" in its symbolic motifs, format and intention. The panels show – from left to right – the birth of Saint John, the baptism of Christ by John in Jordan, and the beheading
Hinged expansion joint joints used in piping systems are restricted to pure angular rotation by its hinges. As a pair, hinged expansion joints will function together to absorb lateral deflection. Advantages of hinged expansion joints are that they are typically compact in size and structurally rigid. Hinged expansion joint A hinged expansion joint is a metallic assembly, that can rotate in a single plane, used to absorb changes resulting from piping thermal expansion or contraction. They include hinges, attached to the expansion joint ends with a pair of pins, which allow angular movement in a single plane, restrain the pressure thrust, and prevent
