Abstract: A joint having a plurality of bars inserted through apertures into a metal casing adapted to be filled with a grout is disclosed. The casing has projecting members that taper in stepwise fashion from an enlarged portion covering the apertures.

Abstract: A process for forming a joint for connecting a plurality of bars in a metal casing includes the steps of pouring a granulated solid into the metal casing and prestressing the solid by driving in a mandrel through the filling aperture of the casing. Thereafter, an unsinkable or a low-shrinkage hardening fluid is injected into the metal casing and permitted to harden.

Abstract: In a joint including a plurality of bars linked thereby, the ends of the bars are inserted through apertures in a metal casing which is filled with a hardening grout. The ends of the bars received in the casing have necked-down portions having two tapered members therein which are oriented with their tapering sections facing in opposition and which are pretensioned toward each other by a tensioning member to contact the walls of the necked down portion in flatwise abutting engagement, in opposite sections of the necked down portion.

Abstract: An endless conveyor includes plural load bearing plates mounted for continual horizontal movement by two endless chains which run in spaced and parallel vertical planes. Each plate has at diagonally opposite corners thereof a pivotally connected main support which is driven by one of the chains. Each plate also has pivotally connected thereto, at only one of the other corners thereof, an auxiliary support which is not driven by a chain but which is laterally aligned with and rotationally connected with a laterally opposite main support. The remaining corner of each plate is unsupported. All of the three supports have rollers which are guided in endless guide rails, such that the plates maintain a constant horizontal alignment.

Abstract: The invention relates to a transfer joint for rigid frames comprising a solid joint member, the interior of which is made of hardened grout and has three or more bars joined to it with a non-positive and/or positive connection.
