Title: Method for minimising the dead space in the combustion chamber of an internal combustion engine
Inventor: HAAS ECKHARD DIPL ING
IPC: F02B23/00
Filed: 1985-08-29
Abstract: The invention relates to a method for minimising the dead space (4) in the combustion chamber (3) of an internal combustion engine, the combustion chamber (3) being defined by the cylinder tube (1), a fixed part such as the cylinder head (5) and a part axially moveable in the cylinder tube such as the piston head (7) and the piston head lying at the top dead centre of the piston (8) at a small distance from the cylinder head (5) and defining the dead space (4). According to the invention a layer of deformable, highly porous sintered metal (6) is applied, at least in areas, to at least one of the parts defining the dead space (4) and the piston (8) so inserted into the cylinder tube (1) that in the TDC position of the piston the dead space (4) is approximately filled and the internal combustion engine then put into service. By this method the compressed layer of sintered metal virtually fully fills the dead space in full load operation of the internal combustion engine. In partial load operation of the internal combustion engine the axial expansion of the piston (8) is less and the dead space increases slightly again. <IMAGE>

Title: Pneumatic or hydraulic shock absorber
Inventor: STOLL KURT DIPL ING
IPC: F16F9/46
Filed: 1985-10-15
Abstract: A pneumatic or hydraulic shock absorber is proposed which has a piston (10) which is longitudinally displaceable in a damping cylinder (11) and divides the latter into two chambers. A connecting channel (15, 16, 17) between the chambers constitutes a flow resistance for a liquid or gaseous working medium in the damping cylinder (11). For remote-controlled adjustment of the damping property, the flow resistance can be adjusted by an electrically controllable actuator (18). This permits, on the one hand, remote control of the damping properties from a control console and, on the other hand, adjustment of the damping properties during operation. <IMAGE>

Title: Printing on a paper sheet with a selectable image section
Inventor: SIMETH CLAUS DIPL ING
IPC: B41F13/48
Filed: 1986-10-06
Abstract: In sheet-fed offset printing machines, register adjustment devices are provided in order to rotate plate cylinders bearing printing plates relative to the other printing unit cylinders. In order to be able to utilise the printing machine better, a method utilising the said devices is to enable printing of changing sections from printing images present on the printing plate. For this purpose, the sheet-fed offset printing machine is moved into at least two different operating positions. A repositioning operation has to be carried out in each case between the two positions. The repositioning is carried out from a starting position with the aid of the register adjustment device in a rough adjustment mode and moves parts of the printing plate which were not previously involved in the printing process into the printing zone. The method can be used, in particular, for the changing impression of printing control strips for a colour regulating system.

Title: Charge-air cooler for internal-combustion engines
Inventor: ENGLER GUSTAV DIPL ING
IPC: F02B3/06
Filed: 1987-02-25
Abstract: A description is given of a charge-air cooler for internal-combustion engines, in particular for water-cooled diesel engines, which is provided with a finned pipe block through which the charge air and water flow and which is arranged between two cooling-water tanks and two side parts connecting the latter. The cooling-water tanks are in this case rigidly connected to the side parts. The material of the side parts is matched to that of the pipes in such a way that the ratio of the coefficients of thermal expansion are approximately inversely proportional to the ratio of the average temperatures in @C to be expected during operation. This configuration makes it possible to dispense with sliding bottoms, because the novel selection of material allows the occurrence of stresses to be reduced to a great extent, in particular in the corner regions between the side parts and the finned pipe block.
