Patent DE-3221762-A1 (DE)
Title: Control device for a diesel-hydraulic drive
Inventor: MESIC IWAN
IPC: F02D29/04
Filed: 1982-06-09
Abstract: The diesel-hydraulic drive provided with a control device according to the invention has an axial piston pump (4) and a plurality of hydraulic motors (8), which have an absorbtion volume which can be switched over. The oscillating shaft of the axial piston pump (4) is provided with electric switches (10a, 10b, 10c, 10d) which, with increasing engine speed of the diesel engine (1) and the associated swinging out of the axial piston pump (4), switch the hydraulic motors (8) over one after the other to the smaller absorbtion volume and, with decreasing engine speed and the associated swinging back of the axial piston pump (4), switch the hydraulic motors (8) back one after the other to the full absorbtion volume again. This achieves the effect that the axial piston pump can operate longer with a relatively better efficiency. <IMAGE>

Patent DE-3227139-A1 (DE)
Title: Pallet for the storage of parts
Inventor: STOCKER HANS
IPC: B65D19/24
Filed: 1982-07-21
Abstract: The pallet (4) is of annular design and has cavities (4c) at the front for receiving the lower ends of elongate small mechanical parts. These cavities (4c) are arranged in radial rows (6) and on concentric circles (7) and alternate with clear spaces on which cavities are arranged on the back of the pallet, these appearing as projections (4d) at the front and being intended to receive the upper ends of the parts. The cavities (4c) and projections (4d) are offset from one row to the next and from one circle to the next. The pallets are mechanically loaded and unloaded. To this end, it is initially sufficient to move the pallet on through successive rotary movements about its centre in order to bring all the cavities (4c) of a circle (7) past a processing station, and then to adjust the pallet laterally in the direction of the arrow (10) so that further circles of cavities are successively moved to the processing stations. <IMAGE>

Title: Process and apparatus for the ignition of solid fuels in a heating boiler designed for solid and liquid or gaseous fuels
Inventor: GROESCHL JOSEF
IPC: F24C1/02
Filed: 1982-08-04
Abstract: In a process for the ignition of solid fuels in a heating boiler designed for solid, liquid and gaseous fuels, and having a filling shaft for the solid fuels and a burner for liquid or gaseous fuels, a reduced pressure field is built up by a flame emerging from the burner nozzle and extending outside the flow path of the combustion gases arising from the combustion of the solid fuels. The solid fuel is ignited by a portion of the flame gases, and the combustion gases are drawn off by the suction which is thus produced. In an apparatus for performing the process, the burner is arranged such that its flame extends, at least at its beginning, outside the flow path of the combustion gases arising from the combustion of the solid fuels.

Title: Textile sheet-like structures which are reinforced by plastics films, for composite materials which are able to withstand high loads
Inventor: KAPS RAINER DR RER NAT DIPL CH
IPC: B63H9/06
Filed: 1982-09-08
Abstract: The claimed process contains a production technology for dimensionally stable, tear-resistant and weathering-resistant sheet-like structures which are suitable for the production of weldable, sewable and bondable sheeting for tents, sails and tarpaulins. This high internal strength of the composite is achieved by using the dry lamination process, which has been modified so that it corresponds to a continuous impregnation process with analogous properties and build-up principle of the glass-fibre-reinforced polyester resins. The choice of woven fabrics and films allows production of a quality matched to the particular application.

Title: Arrangement for the releasable frictional connection between a gearbox input shaft designed as a hollow shaft and a drive shaft which can be inserted into the latter
Inventor: FALK CURT
IPC: F16H57/00
Filed: 1984-05-24
Abstract: The subject-matter of the invention is a releasable frictional connection between a gearbox input shaft designed as a hollow shaft and supported within a housing in spaced bearings and a drive shaft which can be inserted into the abovementioned shaft. To achieve a connection which can be cancelled easily in the event of overloading, an annular chamber (9) having a small radial width and filled with high-pressure fluid is formed in the gearbox input shaft (2). The wall of the gearbox input shaft expands and establishes the frictional connection between the shafts. In order to avoid damage in the bearings (3, 4), the annular chamber (9) extends axially only into the vicinity of the bearings (3, 4) and an arrangement (10), accessible from outside, for setting the pressure in the annular chamber (9) is connected to the annular chamber (9) via a duct (15). <IMAGE>
