Title: Combustible components adsorbed from gas mixt. - after making inert by raising combustible gas concn. above upper explosion limit
Inventor: WEYER HORST DIPL ING
IPC: B01D53/04
Filed: 1980-03-20
Abstract: A method of adsorptive removal of combustible constituents from gas mixts. consists of rendering the mixt. inert before it is treated by the further addn. of a combustible gas. Pref. the total concn. of combustible gases is raised to least 50% above the upper explosion limit. In a variant, additional components are added to raise the combustible gas concentration to this level. Pref. before each operation the adsorber bed is flushed through with a combustible gas. Whereas in prior art methods of rendering the mixt. inert before removing the combustible constituents, it was the practice to dilute with air to lower the concn. to below the lower explosion limit, the new method operates in the opposite direction by raising it to above the upper explosion limit. This results in a considerable redn. in the quantity to be treated and consequently in the size of the adsorber bed required.

Patent DE-3106769-A1 (DE)
Title: Device for the injection of liquid fuel for a reciprocating piston internal combustion engine
Inventor: FUCHS PETER
IPC: F02M55/02
Filed: 1981-02-24
Abstract: The device has an injection valve (6), which is connected to a pressure line (7) connected to a fuel pump (1), and contains a valve needle (8) interacting with a sealing seat (9). In the pressure line (7) a valve (15) maintaining the static pressure in the pressure line is arranged close to the injection valve (6). Between this valve (15) and the chamber (12) of the injection valve (6) to which fuel is admitted upstream of the sealing seat (9) a line (17) branches off, which leads to a chamber in which a pressure prevails which lies below the static pressure prevailing in the pressure line (7). A valve (19), which is controlled so that it opens towards the end of the injection sequence, is located in the line (17). By means of this device it is possible, after the valve needle has closed, to prevent a build-up of pressure in the fuel upstream of the valve seat of the injection valve, so that the valve needle no longer lifts off. The after-dribbling of fuel into the combustion chamber associated with such a lift-off is therefore eliminated. <IMAGE>

Title: Idle speed control device for internal combustion engines
Inventor: HAUBNER GEORG
IPC: F02D31/00
Filed: 1982-06-22
Abstract: The invention proposes an idle speed control device for internal combustion engines having a device (e.g. actuator) controlled by a microcomputer (10) and acting on the internal combustion engine to vary its speed. This variation can, for example, be effected by influencing the fuel/air mixture. Together with the internal combustion engine, the microcomputer forms a control circuit and, as a function of the actual engine speed signals applied and, if required, of further influencing variables, calculates in parallel an engine speed value and an output control signal sequence for the said device (17). This control signal sequence is output on the output side, likewise in parallel. The calculation of the engine speed value takes place in each case following sensor signal flanks and the calculation of a new control signal takes place following the subsequent control signal flank after which, depending on the duty cycle and/or the frequency for the control signal sequence, the larger interval relative to the subsequent control signal flank occurs. In the case of microcomputers without an interrupt and with a relatively slow processing time, this guarantees a rapid execution of the processing operations with the best possible exploitation of the available computation speed. <IMAGE>
