Abstract: Rods or tubes are arranged in a first plurality of layers in which their number increases by one from layer to layer, and in a succeeding plurality of layers wherein they similarly decrease in number. A stack support can be lowered from an uppermost elevation in increments equal to the layer heights. A lateral backing stop comprising two superposed rollers is connected to the stack support and lateral backing arms are spaced from the stop and move relative to the stack support so that the extent of the arms above the support increases as it is lowered. The stop, stack support and arms define four successive sides of a regular hexagonal prism. A plurality of carrying arms are closely spaced above the uppermost elevation of the stack support to receive each layer and support it, the carrying arms being operable to move therewith to a position over a portion of the support between the stop and backing arms, and then to a position beyond the stop.

The valve member has a neck portion of reduced diameter between the valve seat and the piston and the annular cross section, being acted upon in closing direction, between the neck portion and the circumference of the piston is smaller than the annular cross section, being acted upon in opening direction, between the neck portion and the valve seat.

Abstract: In a method and apparatus for cutting minerals utilizing a cutting tool provided with cutting teeth, the tool rotates about an axis approximately parallel to the winning face and is moved at a feeding rate essentially in axial direction. Several grooves spaced from each other are carved in sequence, and in dependence on the mineral properties the feeding rate is increased with respect to the rotatory velocity when a brittle mineral is to be cut, while the feeding rate is diminished with a tough mineral.

Abstract: An arrangement for introducing a flexible starter bar with a starter bar head from above into a continuous casting plant including a mould, a strand guide and an introduction part and has a lifting mechanism for the starter bar, a transporting car. The transporting car contains a sliding or roller path having arcuate end parts for transporting the starter bar to the introduction part and a conveying device for the starter bar provided on the transporting car. The conveying device is designed as a displacement car and is movable on the transporting car in the longitudinal direction of the sliding or roller path for introducing the starter bar into the introduction part. First and second catches are provided on the displacement car for engagement with the starter bar.

Abstract: A cutting machine having a universally movable cutting arm and cutting head assembly and a movable loading ramp assembly thereunder and means operatively associated with the cutting arm and loading ramp for controlling the operation thereof so as to prevent contact between the cutting arm and loading ramp by maintaining the vertical spacing therebetween in excess of a predetermined minimum.

The lifting table is perpendicularly displaceable relative to the conveying-roller-path plane. An inclined sliding path extending transversely to the strand guide is formed when the lifting table has been lowered and the arms are pressed into the tilted position by the weight of the cut off strand piece.

Abstract: A releasable hub-shaft connection mechanism, in particular to be used in heavy machinery for transmitting strong torques, has a shaft, a hub surrounding the shaft and at least one bore with its axis parallel to the shaft and located at the junction of the shaft and the hub so as to penetrate each equally.
