Abstract: A connecting arrangement for a hard-material plate, block or other member, serving as a support for a liquid-permeable web in a paper making or similar machine, in which the hard-material body, e.g. an oxide ceramic, receives a clip which also engages a rigid support for the body. According to the invention slots are formed in the hard-material body and are of circular-arc configuration whose inner radius is at least 1/2% smaller than the curvature of the free shanks of the clip engaging in the grooves.

Abstract: A papermaking machine has a dewatering mesh that passes over and is supported by a plurality of parallel dewatering bars extending transversely of the displacement direction of the mesh. Each bar has an elongated ceramic upper surface formed with a sharp front edge directed into the mesh displacement direction and each bar is carried on and displaceable along a transversely extending support guide so that it can be drawn transversely out from underneath the mesh and can be reinserted transversely thereunder. The upper surface and the sharp front edge of the bar are rounded at one end of the bar so that this bar can be displaced transversely under the mesh with this one end out of contact with the mesh during the operation of the machine and passage of the mesh over the sharp edge of the guide bar.

Abstract: A solid or perforated plate, serving as a support for a screen conveyor in paper-making machinery or the like, consists of a multiplicity of juxtaposed coplanar sections of sintered refractory, predominantly ceramic material joined to one another by thin layers of a bonding agent. The ceramic component, e.g. alumina, may be admixed with a small proportion of a vitreous substance facilitating the use of a siliceous bonding agent, such as glass, enamel or silicon carbide. Alternatively, the bonding agent may be a solder (with preliminary metallization of the adjoining section edges) or an organic cement.

Alternatively, the bonding agent may be a solder (with preliminary metallization of the adjoining section edges) or an organic cement.A method for making the plate includes filling gaps between the sections with a bonding agent of silicon carbide formed by melting pieces of graphite in the gaps in an atmosphere of silicon vapor, thereby uniting the sections.
