Patent DE-4022049-A1 (DE)
Inventor: NETT HANS-PETER
IPC: B60K17/00
Filed: 1990-07-11
Abstract: In order to keep the sound emission of vehicle drives with a hydrostatic drive system within tolerable limits, it is customary to encapsulate the hydrostatic drive in a vehicle gearbox. The hydrostatic drive is supported in relation to the gearbox via structure-borne noise damping components seated in axial drillings of large diameter in the gearbox into which the hydrostatic drive is pushed axially with correspondingly large cylindrical bearing surfaces. Owing to his feature, if the damping components need repair or exchange, the hydrostatic drive can be dismantled only when the gearbox itself has been taken apart. In order to reduce the effort of such work, the hydrostatic drive (5) is insertable via a closable aperture (1a) in the gearbox (1) and is borne in the operative position by rods (14, 15) arranged obliquely to the drive shaft (8) and the output shaft (9) of the hydrostatic drive (5) which are supported at the end via annular, structure-borne noise damping components (17, 21) inserted in through holes (1b) in the gearbox and firmly secured to the casing of the hydrostatic drive (5).

Patent DE-4112633-A1 (DE)
Inventor: KULLBERG JUN WILHELM
IPC: B65D5/40
Filed: 1991-04-18
Abstract: A process and a device for closing an aperture in a tubular container designed especially for fluids and consisting of paper or cardboard with a sealing coating on at least one side, involve closing the upper container aperture by folding the four container sides at the top over one another and securing them. To allow the closure to be easily opened by pulling up one side of the closure to form a pouring lip and to sealingly secure the four folded container sides, a foil-like sealing component is adhesively secured to the inner surface of the front of the container after folding of the sides. Thus, in particular, the free folded edges of the container sides are sealed and firmly secured to the bordering regions of the adjacent sides without the surfaces folded on top of one another being stuck together. When the container is opened by pulling up the pouring lip side of the closure, the sealing component is easily separated along the folded sides to which the pulled-up side is attached, thus facilitating opening the closure.
