Patent DE-3906565-A1 (DE)
Title: Arcuate structural element
Inventor: WULFERT KARL-LUDWIG
IPC: E04F11/18
Filed: 1989-03-02
Abstract: The invention describes an arcuate structural element (1) and a process and an apparatus for producing the same. The structural element (1) comprises a pre-bent metal insert (2) and portions (3, 4) of a plastic sheathing which have been pushed thereon. The metal insert (2) has a length corresponding to the length of the structural element (1), but each portion (3, 4) has, in contrast, a shorter length. Consequently, the mutually facing end surfaces of the portions (3, 4) would normally be separated by a wedge gap, even in the case of mutual abutment. In order, however, to obtain an extremely fine joint (12), once the portions (3, 4) have been pushed onto the metal insert (2), first of all said end surfaces are subjected to machining, in order to convert them into mutually parallel abutment surfaces, and then the portions (3, 4) are advanced towards one another until they abut (Fig. 3). <IMAGE>

Title: Method for the operation of an internal combustion engine and device for performing the method
Inventor: SCHWEINZER FRANZ DIPL ING
IPC: F02D15/04
Filed: 1989-03-14
Abstract: The invention is a method for the operation of an internal combustion engine, especially a four-stroke internal combustion engine, the gas being drawn from the cylinder during the compression and combustion stroke and fed to it again during the expansion phase. In this, relatively highly compressed gas, which still contains sufficient oxygen, is used for recombustion in the expansion phase in that it is stored in an intermediate reservoir from the compression and combustion phase until the expansion phase. Excessively high cylinder pressures are avoided but a higher pressure level is maintained in the cylinder as long as possible during the power stroke. In a preferred device for performing the method the intermediate reservoir (21) with a transfer port (10) to the cylinder is formed by a housing (11) seated on the cylinder head (3) of the internal combustion engine and two valves (15, 16) are provided in the housing (11) for controlling the transfer port (10), of which the main valve (15) of larger diameter is spring loaded, has its seat (22) inside the housing and opens in the direction of the intermediate reservoir (21), and the compensating valve (16) of smaller seat diameter has its seating face (30) on the end face of the main valve (15) and opens in the direction of the cylinder. <IMAGE>
