Abstract: A pole for a hand pallet truck that includes a pole bar which is linked to a support for a steerable wheel at its lower end and connected to a loop-shaped handle at the other end. An operating device is disposed within the space defined by the handle. The operating device is attached to a holding extension projecting into the handle in prolongation of the bar, and is connectable to a lifting apparatus of the hand pallet truck via a traction and/or pushing element. If applicable, it is connectable via a second traction and/or pushing element to a brake of the hand pallet truck, wherein an operating lever is disposed on either side of the extension. The operating levers are pivotally mounted on the holding extension in a plane essentially defined by the handle.

Abstract: Pump assembly for the lift cylinder of a hand fork-lift truck includes a piston pump activated by a bar of a hand fork-lift truck and has a piston chamber and an annulus collector. A three stage control valve connects the lift cylinder with a tank in the lowered setting and connects the piston chamber with the tank in a neutral setting and in a pump setting, connects the piston chamber with the lift cylinder through a first check-valve, with the tank through a second check-valve, a third check-valve between the piston chamber and the annulus collector open to the piston chamber, and a reversing valve between the piston chamber and the annulus collector.

Abstract: In a textile spinning apparatus a yarn joining device (12) begins to work to join the end of a newly spun yarn with a retrieved yarn end after the breakage of a yarn (2). During the joining process draw-off rollers (3) continue, to supply the yarn (2) such that yarn storage members (4, 11) have to be implemented during the joining process. In order to draw the yarn (2) into the interior of the yarn storage members (4, 11), air suction is applied in a known manner. After the yarn (2) joining process is completed in the yarn joining device (12), the yarn storage members (4, 11) are successively emptied by use of an acceleration in yarn draw off speed effected by a yarn storage draw-off roller (7) and an auxiliary friction roller (14).
