Title: Discharge mechanism for rotary loader wheel - has horizontal adjustable deflector plate at bottom of chute overlapping the conveyor belt
Inventor: FIRLAY KARL-HEINZ
IPC: B65G65/20
Filed: 1973-06-19
Abstract: From the shovels of the loader wheel, the material slides down a fixed inclined shute. The distance and angle of the overlapping plate edge relative to the axis of the conveyor belt determines the parabola at which the material hits the conveyor. This in turn determines the even loading of the conveyor which improves the belt position on the rollers. This method allows the shute to be kept steeper and shorter, thus the loader wheel can be of smaller diameter which results in reduced machinery building costs.

Patent DE-2344263-A1 (DE)
Title: Shock absorber for rail mounted cranes - two telescopic parts in housing filled with gas filled cells
Inventor: KESSEL HEINRICH
IPC: B60R19/32
Filed: 1973-09-01
Abstract: The application is for use where particularly high shock loads are envisaged. Current designs use either closed cells filled with gas or cells with pores that allow the gases to escape with a throttling effect. This design overcomes the problem that sudden application of extremely high loads can cause the walls to collapse. The gas filled cells rest on one another with only part of their periphery in contact. As they are forced together the normal spherical shape is changed to a near rectangular shape. The zones between the cells remain of almost constant size as they are filled with pulverised material.

Title: Threader for looping yarns wholly or partly round rollers - pneumatic attachment feeds through enclosed roller banks
Inventor: LENK ERICH DR ING
IPC: D01D7/00
Filed: 1974-02-08
Abstract: Rollers in yarn handling and processing machines, rotating freely or positively driven, around which a thread is to be fully or partly looped, have a tub ular pneumatic attachment for laying on the thread, consisting of a tube curved in a plane at right angles to the axis of the roller so as to extend through the angle enclosed by the loop of yarn, and having a lengthways slot facing the roller surface. When a number of threads are to be looped around the roller, the tube may be movable on a support rail parallel to the axis of the roller, whilst for looping the yarn round rollers in different planes, the tubes enclose both angles and have a vertical slot. When the thread is presented to the tube, the compressed air is switched on and injectors transport the yarn which pulls through the slot into place. The simplified and improved arrangement of the rollers enables the thread to be laid on automatically. Lighter and smaller frames take higher tensile loading on the rollers.
