Abstract: The gearbox includes a multi-shaft toothed-wheel planetary gearing and a continuously adjustable hydrostatic transmission having toothed-wheel auxiliary transmission stages and gear-changing clutches. The hydrostatic transmission is associated with a displacement-type machine with constant displacement volume. In the planetary gearing, one shaft forms the input shaft to which the adjustable displacement-type machine is connected. A second shaft of the planetary gearing is connected to the constant-volume displacement-type machine. Third and fourth shafts of the planetary gearing represent coupling shafts. The coupling shafts alternately act via at least two auxiliary transmission stages, also called gears, on the output shaft. The coupling shafts change their speeds in such a manner that one coupling shaft becomes steadily faster and the other one becomes steadily slower. They behave in such a manner that they exhibit equal speeds in one extreme position.

Abstract: The gearing consists of a four-shaft toothed-gear planetary (epicyclic) transmission and a parallel, infinitely variable hydrostatic transmission, as well as additional gear wheels; toothed clutches achieve the various gears (speeds), whereas the hydrostatic transmission effectuates the infinitely variable adjustment of the infinitely variable transmission of the entire gearing; the gear shifting takes place at a synchronous speed of rotation, load-free, and without interrupting the tractive force. The special characteristic consists in the design of the toothed clutches and the control that has been provided for the shifting action, the effect being that the shifting into a new gear and out of the previous one is completely smooth and free of jolts. Apart from provding this comfortable and easy shifting action, the gearing also possesses an extensive range, overall, of transmission adjustment capability, as well as a good efficiency factor. Thus, it is very suitable for application in motor vehicles.

Abstract: Manufacture of double or plural pane insulating packages by placing panes together with a spacer, thereby leaving an interspace at the periphery into which cement is injected. Two nozzles are used to inject cement into the interspace, starting from a common starting region and working in opposite directions around the periphery to a common terminal point. Conveyors and control systems are provided to mechanize the process.
