The catch 8 is mounted in a through hole 10 of the catch yoke 2, the strongly inclined wall 11 of the said hole 10 being so situated that it enables the catch to be introduced only in a case when the connecting member 1 has been inclined relative to the conveyor axis.

Abstract: An inertial conveyor has at least one transporting surface or section slidably arranged on rails with the rear end of the section sliding over an immovable rest, shifting means, preferably an adjustable spring, which permits the section to shift toward the rest and drive means for delivering lateral driving impulses of acceleration in one direction with an acceleration which is more than the acceleration of the friction force of any material on the surface to the section. The shifting means in between the driving impulses delivering lateral movement to the section in the opposite direction with less acceleration than that of material thus causing a non-harmonic movement so that the friction force will be overcome and material on the surface will move toward the immovable rest. In a preferred embodiment the inertial conveyor includes a plurality of sections and is part of a grate stoker.

Abstract: An electromagnetically actuatable valve is proposed, which serves in particular to inject fuel into the intake tube of internal combustion engines operating with fuel injection systems. The fuel injection valve includes a valve housing, a shell-type core having a magnetic coil, and a flat armature. The flat armature is firmly connected with a spherical valve element which passes through a central guide opening in a guide diaphragm and cooperates with a fixed valve seat. The guide diaphragm guides the valve element in the radial direction toward the valve seat. The flat armature contacts the guide diaphragm via a concentric shoulder providing tension thereto so that the armature is guided in a plane parallel to the end face of the shell core. The fuel supply to the valve is effected via radial inlet openings in the valve wall.

In a second embodiment, which may be used with or without step bearing plates, raised curb members, which are attached to both sides of escalator step treads to minimize the gap between the moving escalator steps and adjacent stationary skirt panels, are shaped so that when an escalator passenger steps upon this curb member, it is firmly pressed against the adjacent skirt panel.

Abstract: Method and apparatus of conveying a sheet in a turning action to alter its path of movement. The operator has the option of conveying the sheet through a bump turn mode or a flow turn mode. In the bump turn mode, the original sheet leading edge on a first conveyor is not the leading edge on the second conveyor but instead the sheet side edge becomes the leading edge. In the flow turn mode, the operator can drive the conveyor members of the first conveyor so that the sheet is rotated ninety degrees on the first conveyor and is then deposited onto the second conveyor so that the sheet leading edge on the first conveyor is also the leading edge on the second conveyor. The apparatus consists of a first conveyor and a second conveyor with the first conveyor having individually driven members for the optional modes mentioned.
