Abstract: A drive point for a substantially tubular, in particular hollow cylindrical, driven pile having a pile core through which concrete can be introduced into the driven pile, wherein the drive point can be fitted onto a pile end of the driven pile, wherein at least one first supporting web with a first contact surface for an end face of the pile end is arranged on an inner wall of the drive point, wherein starting from a plane of a first bearing surface the drive point has a cavity which extends at least partially in a driving direction and into which concrete can be introduced through the pile core when the driven pile is fitted, wherein at least one concrete outlet channel is provided which connects the cavity to an upper edge of the drive point.

Abstract: The invention relates to a drive point for a substantially tubular, in particular hollow cylindrical, driven pile having a pile core through which concrete can be introduced into the driven pile, wherein the drive point can be fitted onto one end of the driven pile, wherein at least one first supporting web with a first contact surface for an end face of the pile end is arranged on an inner wall of the drive point, wherein starting from the plane of the first bearing surface the drive point has a cavity which extends at least partially in the driving direction and into which concrete can be introduced through the pile core when the driven pile is fitted, wherein at least one concrete outlet channel is provided which connects the cavity to an upper edge of the drive point.

Abstract: A spigot-and-socket joint for connecting two pipes, comprising a socket end assigned to one pipe and into which a spigot end of the other pipe, which has a support strip, can be inserted and which has a radially inward-protruding edge with at least one ring segment-shaped recess, and a locking device for locking the spigot end in the socket end. The support strip rests against the locking device and the locking device rests against the edge. The locking device comprises at least two ring segment-shaped locking elements. At least four recesses are provided and are arranged with uniform spacing circumferentially, and the two locking elements each have two ring segment-shaped locking parts which are joined together via a respective web. The spacing between the two locking parts of a locking element corresponds to the spacing between two recesses.

Abstract: The present invention relates to a spigot-and-socket joint for connecting two pipes, pipe fittings or the like, comprising a socket end (16) which is assigned to one pipe and into which a spigot end of the other pipe, which has a support strip (64), can be inserted and which has a radially inward-protruding edge (20) with at least one ring segment-shaped recess (26-29), and a locking device for locking the spigot end in the socket end, in that the support strip rests against the locking device and said locking device rests against the edge, the locking device comprising at least two ring segment-shaped locking elements.

Abstract: A casting device in particular a converter for pouring and/or treating of molten metal is provided with a tilting mechanism. A tilting arm with two turn- or tilting axles at least is provided for. A guiding segment allied to the tilting arm show--according to the relation to the tilting axle--different arc radii. The segment is motor-driven and spanned by one chain at least.

Abstract: A spigot and socket joint includes an annular locking member surrounding the spigot member, an annular part surrounding the locking member and a clamping collar engaging radial flanges on the annular part and on the socket member to hold the annular part against the locking member. The locking member can be releasably clamped to the spigot member or a stop can be secured to the circumference of the spigot member to limit axial movement of the locking member toward the socket member.
