Filed: 1991-05-14
Abstract: The invention relates to a transmission, in particular a transmission for agricultural or commercial vehicles, having at least two shafts (12, 60a, 60b) arranged parallel and adjacent to one another. In order to be able to use comparatively small shaft diameters, at least one of the shafts consists of two mutually aligned, axially spaced part-shafts (60a, 60b) which are connected positively to one another by a torsion shaft (71). The torsion shaft (71) is thus arranged without an offset of the axes between the two part-shafts (60a, 60b). 
<??>A particularly preferred area of application of a transmission of this kind is in a hydrostatic-mechanical split-torque transmission with a continuously variable transmission ratio for motor vehicles, in particular for agricultural or commercial vehicles. The transmission consists of a hydrostatic transmission continuously adjustable between two extreme positions and having one displacement machine (18) of variable volume and one displacement machine (24) of constant volume, and of a summing mechanism which contains at least two planetary gear trains (28, 32). Using a plurality of gear-changing clutches (68, 70), it is possible to set gearwheel shift stages (I, II, III, VI) by a procedure in which the output shafts (44, 52) of the planetary gear trains (28, 32) are connected via gear wheels with different transmission ratios to a transmission output shaft (60a, 60b). In order to permit a compact construction of the transmission, not only is a torsion shaft (71) used, but different individual setting ratios are provided for at least two shift stages.

Patent DE-4229317-A1 (DE)
Inventor: CHODORA JOSEF
IPC: H01J61/073
Filed: 1992-09-02
Abstract: To improve the operation of high-pressure discharge lamps by preventing premature deformation of the end face of an anode due to extremely high temperature, with subsequent vaporization of tungsten material from the electrode and deposition on the bulb or vessel of the high-pressure discharge lamp, the electrode is axially forged, for example by hammering, to compact and change the grain structure of the electrode towards a finer grain than elsewhere in the electrode and increase the hardness of the electrode across the end face surface. Both-higher density and finer grain structure-increase the parameters which characterize the lifetime of electrodes, and hence of the lamp, namely heat conductivity and resistance against deformation under heat stress.
